ATTACHMENT SYSTEM FOR MODULES IN A VEHICLE

CROSS-REFERENCE TO RELATED PATENT APPLICATIONS

[0001] The present Application claims the benefit of priority, as available under 35 U.S.C. § 119(e)(1), to U.S. Provisional Patent Application No. 60/52S,906 titled "Attachment System for Modules in a Vehicle" filed on December 11, 2003 (which is incoiporated by reference in its entirety).

BACKGROUND

[0002] The present invention relates to an attachment system for modules for a vehicle. The present invention relates more particularly to a system for interchangeably attaching modules for use in a vehicle. The present invention relates more particularly to a system for attaching modules for use in an overhead system for a vehicle.

[0003] Placement of modules for use in an overhead location or other location of a vehicle are generally known and may include one or more modules such as storage compartments, bins, instrumentation, entertainment devices and the like. Such modules are typically formed with (or attached to) a console or other trim piece, in which the modules are often permanently, or semi-permanently, attached to the internal structure of the vehicle by attachment devices such as threaded fasteners, spring-clips, "Christmas tree" fasteners, or the like.

[0004] However, such known attachment devices typically are not intended to permit a user to conveniently remove one module and replace it with another module. Such known attachment devices also do not usually provide a user with the capability to rearrange the position of several modules, or to customize the content and position of the modules within the vehicle in a convenient manner.

[0005] Accordingly, it would be advantageous to provide an attachment system for modules that provides secure retention of the module within the vehicle. It would also be advantageous to provide an attaclinient system for a vehicle that provides secure retention of the module in a vertical direction and a horizontal direction. It would also be advantageous to provide an attachment system for modules that permits the module to be easily and conveniently installed, removed, or replaced with other modules. It would be further advantageous to provide an attachment system for modules that is configured for concealment within the module to enhance the aesthetic appearance of the module. It would be further advantageous to provide an attachment system for modules that is configured to fit within a compartment along a surface of the module to minimize inadvertent contact with the attachment system. It would be further advantageous to provide an attachment system for modules that provides an indication when the module is not properly attached.

[0006] Accordingly, it would be advantageous to provide an attachment system for a module having any one or more of these or other advantageous features.

SUMMARY

[0007] One embodiment relates to an attachment system for a module configured to be coupled to at least one rail member in a vehicle. The system includes a latch member coupled to the module and movable between an engaged position to secure the module to the rail member and a released position to permit removal of the module from the rail member. An actuator portion on the latch member is configured for movement in a first direction and a second direction by a user. An engagement portion on the latch member is configured to engage the rail member, whereby the module is attachable to the rail member by moving the actuator portion in the first direction so that the engagement portion engages the rail member and the module is releasable from the rail member by moving the actuator portion in the second direction to disengage the engagement portion from the rail member.

[0008] Another embodiment relates to a latching apparatus for coupling a module to at least one rail member in a vehicle. The apparatus includes a first latch member coupled to the module and for movement between an engaged position to couple the module to the rail and a released position to permit removal of the module from the rail. A second latch member coacts with the first latch member and the module so that the second latch member is movable between a locked position where the first latch member is locked in the engaged position and an unlocked position where the first latch member is movable to the released position.

[0009] A further embodiment relates to a latching device for coupling a module to at least one rail member. The device includes a primary latch member coupled to the module and having a hook member for movement between an engaged position to couple the module to the rail and a released position to permit removal of the module from the rail. A secondary latch member is coupled to the module to coact with the primary latch member so that the hook member engages the rail member when a handle portion of the secondary latch member is moved to the engaged position and the hook member disengages the rail member when the handle portion is moved to the released position.

[0019] The attachment system for a module (e.g. articles, components, objects, etc.) is shown and described for modules configured to attach to structure disposed on an overhead portion of a vehicle (shown schematically as "rails" or other elongated members positioned on an "A" surface of a "headliner" or other panel) according to the illustrated embodiments. However, the description of the various embodiments of the attachment system for a module are equally applicable to attachment systems for other locations within a vehicle (such a floor areas, cargo storage areas, seat backs, side panels, etc.) and to other suitable structures (e.g. other trim components, structural members of doors, floors, roofs, etc.)

[0020] Referring to FIGURE 1, one example of a representative module 10 for use in a veliicle is shown schematically positioned on an overhead panel 12 (such as the A surface of a headliner, etc.) within the vehicle and attached to elongated members shown schematically as extrusions, tracks, rail members or "rails" 20. The modules are intended to be conveniently installed, removed, replaced and repositioned along the rails by the attachment system.

[0021] Referring to FIGURES 2 and 4, one embodiment of rail 20 is shown schematically as including recesses 22 that extend longitudinally along a side area, and a receptacle 24 (e.g. pocket, well, channel, etc.) configured to retain an insert 26, such as a positioning insert (also shown schematically in FIGURE 3), and an opening 28 that extends longitudinally along a lower surface, and a trim member 30 configured to fit within opening 28 for selective access to an interior space 32 within rail 20.

[0022] Referring to FIGURES 2-4, the insert (shown schematically as a positioning insert 26) is configured for placement in connection with rail 20 and to interface with a module 10. According to one embodiment, positioning insert 26 may slide longitudinally into receptacle 24 and is retained by a lip 34 extending inward adjacent recess 22. The positioning insert 26 is shown having a module interface portion with engagement structure 36 configured to operably engage corresponding structure on the attachment system of the module and intended to prevent the module from moving longitudinally along rail 20. The engagement structure 36 provides a surface contour shown schematically to include a series of peaks and valleys (e.g. ridges, saw tooth, etc.). According to one embodiment, the positioning insert is made from a polycarbonate material, but may be made of any suitable material such as plastic, glass-filled polypropylene, rubber, or a metallic material such as aluminum, steel, etc. According to an alternative embodiment, the positioning insert may be integrally formed with the rail, or provided in any suitable location on the rail. For example, "saw teeth" may be cut or otherwise formed in the rail or apertures such as holes, slots, windows, etc may be foπned in the rail and configured to engage a portion of a latch member. According to another alternative embodiment, the engagement stmcture may have any suitable shape and form (e.g. a series of apertures, pegs, a roughly- textured frictional surface, etc.).

[0023] According to any preferred embodiment of the attachment system, the recesses, openings and/or contour on the positioning insert of the rail are configured to coact with structure provided on or with the modules to permit the modules to be conveniently and securely attached or coupled to the vehicle interior (e.g. such as via the rails).

[0024] Referring to FIGURES 2 and 4 through 6, an attaclinient system for a module is shown according to one embodiment. The attachment system includes a latch member 40 shown as positioned on each side of the module. The latch member 40 is movable between an "engaged" position to secure module 10 to rail 20 and a "released" position to permit removal of the module from the rail.

[0025] The latch member 40 is shown to include an actuator portion 42, an engagement portion 44 and a pivot portion 46. The actuator portion 42 has a pad 48 (e.g. push button, etc.) shown to be generally "flush" with an outer surface 50 of the module when latch member 40 is in the engaged position to provide a smooth and relatively uniform appearance. The actuator portion 42 may be deployed or actuated by moving (e.g. depressing) pad 48 inwardly (relative to the module) to move latch member 40 from the engaged position to the released position. According to an alternative embodiment, the actuator portion and/or pad may be configured in a suitable relationship with the wall of the module (e.g. recessed, projecting, etc.).

[0026] According to an alternative embodiment, the actuator portion may be configured to provide an indication in the event that the latch member is not fully or positively engaged for attachment of the module to the rail. For example, the indication may provide a visually perceptible signal that the latch member is not completely engaged with the rail. The visually perceptible signal may be a marker (such as a "flag" or a "pop-up button" or the like) having a color (e.g. red, orange, yellow, etc.) intended to attract the attention of a user. The marker is configured to be visible (e.g. extended, projected, etc.) to a user when the latch member is not completely engaged with the rail, and to be relatively hidden (e.g. withdrawn, retracted, etc.) when the latch member is completely or positively engaged with the rail.

[0027] The engagement portion of the latch member 40 is shown to include a hook member 52 having stmcture configured to enter recess 22 and engage positioning insert 26. The stmcture may be a tapered surface or other suitably contoured surface intended to facilitate self-engagement or alignment with the recess and/or the engagement stmcture. The hook member 52 is sized for a relatively "snug" fit within recess 22 to minimize movement of the module in a vertical direction (e.g. along a Z axis). The end of the hook member 52 is shown as having a tapered surface to facilitate entry of hook member 52 into recess 22. The end of the hook member may also be contoured (e.g. peaks and valleys, apertures, pegs, ridges, etc. - not shown) to correspond with the engagement stmcture of the positioning insert so that when the latch member is in the engaged position, the end of the hook member and the engagement stmcture of the positioning insert are configured to coact to prevent movement of the module along the length of the rail (e.g. along an X axis). According to alternative embodiments, the hook member may be configured to engage recesses, apertures or other stmcture formed on the rail.

[0028] According to any preferred embodiment, the hook member may be provided with stmcture intended to engage (e.g. mate, interlock, intermesh, fit, etc.) with the stmcture or contour of the rail or a positioning insert provided with,the rail. The hook member of the engagement portion is configured to move between a first position where the module is intended to be removable from the rail(s) and a second position where the module is not intended for removal from the rail(s).

[0029] The pivot portion 46 of latch member 40 is shown as being located between actuator portion 42 and engagement portion 44 and is configured to permit pivotal movement of actuator portion 42 and engagement portion 44 about the pivot portion (e.g. "seesaw" or "rocker arm" type motion, etc.). According to an alternative embodiment, the pivot point may be provided at any suitable location, such as above the engagement portion, below the actuator portion, etc. [0030] The pivot portion 46 is further shown to include a biasing member 54 (such as a compression spring, or alternatively a coil spring, torsion spring, etc.) configured to bias hook member 52 into engagement with rail 20 and to bias pad 48 into position within the housing of the module. According to an alternative embodiment, other biasing members may be provided such as tension or compression springs positioned at an offset from the pivot point, or leaf-type springs, etc.

[0031] According to any preferred embodiment, the latch member of the attachment system is intended to provide a portion that may be easily and conveniently actuated by a user for attaclinient or removal of a module, and an engagement portion that positively engages stmcture on the rail to prevent movement of the module along at least an X axis and a Z axis. (The stmcture of the module housing is shown abutting a side of the rail opposite the latch member for restraining motion of the module along a Y axis).

[0032] Referring to FIGURES 7-8C, an attachment system for a module is shown according to another exemplary embodiment. The attachment system includes a latch device 60 having a first (e.g. primary, etc.) latch member 62 and a second (e.g. secondary, back-up, lock, etc.) latch member 64. The primary latch 62 and secondary latch 64 are each movable between a released (e.g. disengaged, etc.) position (see FIGURE 8C) to permit removal of a module from a rail, and an engaged (e.g. latched, retained etc.) position (see FIGURE 8A) to secure the module to the rail. The primary latch member 62 is intended to provide a positive latching engagement with the engagement stmcture on rail 20. The secondary latch member 64 is intended to secure primary latch member 62 in the engaged position and prevent inadvertent or unintentional release or disengagement of the primary latch member 62 from the recess 22 shown along an "outward" surface or side of the rail. In operation, the module may be attached to the rail by positively engaging the primary latch member 62 with the rail 20 by moving primary latch member 62 from the released position to the engaged position, and then securing primary latch member 62 in the engaged position by moving secondary latch member 64 from the released position to the engaged position.

[0033] The primary latch member 62 includes a body member having an actuation portion 66, a pivot portion 68 and an engagement portion 70. The engagement portion 70 includes a hook member 72 having contoured stmcture configured to enter recess 22 and engage (e.g. intermesh, coact, etc.) the engagement stmcture on the positioning insert (or rail) as previously described.

[0034] The pivot portion 68 of primary latch member 62 is shown positioned at a point that permits operation of actuation portion 66 and engagement portion 70 in a pivoting manner (e.g. "seesaw" or "rocker arm" type movement about a pivot point).

[0035] The actuation portion 66 of primary latch member 62 is shown as a "ledge" beneath pivot portion 68 which may be pushed downwardly and/or inwardly in a pivoting manner about pivot portion 68 to actuate primary latch member 62 from the engaged position (see FIGURE 8A) to the released position (see FIGURE 8B). In operation, downward or inward movement of actuator portion 66 tends to pivot primary latch member 62 about pivot portion 68 so that engagement portion 70 is moved between the engaged position and the released position in relation to the rail.

[0036] The secondary latch member 64 includes a retainer portion 74 and a release portion 76. The secondary latch member 64 is configured to pivot about a pivot point 78 on primary latch member 62 between an engaged position (see FIGURE 8 A) and a released position (see FIGURE 8B). The retainer portion 74 includes an end 80 that is configured to abut an inside surface of a wall 82 of the module when secondary latch member 64 is in the engaged position, to prevent hook member 72 on primary latch member 62 from withdrawing from recess 22 in the rail. When retainer portion 74 is moved from the engaged position to the released position (as shown in FIGURES 8B-8C), the end 80 moves toward an opening and is no longer restricted by wall 82 of the module, so that hook member 72 of primary latch member 62 is free to move toward the released position.

[0037] A biasing member 84 (shown for example as a tension type spring) is shown connected between secondary latch member 64 and pivot point 68 on primary latch member 62 to provide a biasing force that tends to retain secondary latch member 64 in the engaged position and is intended to prevent primary latch member 62 from inadvertently or unintentionally disengaging from the rail. According to alternative embodiments, the biasing member may be any suitable spring device, connected to suitable stmcture in any desirable arrangement to provide retention of either the primary latch member or the secondary latch member. [0038] Referring to FIGURES 9A-9D, an attachment system for attaching a module to one or more rails in a vehicle is shown according to a further exemplary embodiment. The attachment system includes a latch device 90 having a primary latch member 92 and a secondary latch member 94 and a third latch member 96.

[0039] The primary latch member 92 includes a hook member 98. The secondary latch member 94 includes a handle portion 100, and a catch stmcture 102. The hook member 98 is pivotally coupled to the module at a pivot point 104 for movement between an engaged position (see FIGURES 9A-9B) and a released position (see FIGURE 9D) with the engagement structure of the rail (as previously described). The hook member 98 further includes a peg member 106 (e.g. pin, axle, projection, etc.) extending therefrom and configured to engage a slot 108 on the secondary latch member 94 in a sliding relationship.

[0040] The handle member 100 is pivotally coupled to the module at a pivot point 110 for movement of the handle member 100 between an engaged position (see FIGURES 9A-9C) where the hook member 98 is moved into engagement with the recess 22 along an "outside" surface of rail 20, and a released position (see FIGURE 9D) where the hook member 98 is withdrawn from (e.g. disengaged from) recess 22 of rail 20. The slot 108 is configured to_> coact with the peg member 106 in a sliding relationship, so that when the handle portion 100 is moved to the released position, the slot 108 and peg member 106 coact to disengage the hook member 98 from the recess in the rail, hi a similar manner, when the handle portion 100 is pivoted about the pivot point 110 to the engaged position, the peg member 106 and slot 108 coact to move the hook member 98 into engagement with the rail. The secondary latch member 94 includes a catch stmcture (shown located near a lower portion of the handle member 100) configured to coact with the third latch member 96 and intended to retain the primary latch member 92 in the engaged position and to prevent inadvertent or unintentional disengagement of the hook member 78 from the rail.

[0041] The third latch member 96 is coupled to the module at a pivot point 112 for pivoting movement between an engaged position and a released position. A catch 114 (protmsion, projection, finger, etc.) is provided on the third latch member and configured to engage catch stmcture 102 of handle portion 100 when the handle portion is moved to the engaged position, so that the secondary latch member 94 is retained in a position that is intended to prevent the hook member 98 from disengagement with the rail. To release the module 10 from the rail 20, the third latch member 96 may be moved (e.g. pivoted, etc.) to the released position (shown for example as an upward direction in FIGURE 9B) to release catch 114 from catch stmcture 102 so that handle portion 100 may be pivoted from the engaged position to the released position. The third latch member 96 is shown as including a biasing member 116 (e.g. tension spring, etc.) configured to bias the third latch member toward the engaged position to retain the handle portion 100 in the engaged position so that the hook member 98 remains engaged with the recess 22 of rail 20, until released by a user. According to alternative embodiments, the biasing members such as springs or elastic members may operably engage the primary and/or secondary latch members for biasing the latch device toward either a latched position and/or a released position.

[0042] According to any preferred embodiment, the attachment system for a module for a vehicle is intended to provide an attachment system that is easily and conveniently accessible and operable by a wide variety of users to remove, replace, reposition, and/or install one or more modules within a vehicle, such as within or in connection with, an overhead system for a vehicle having one or more elongated members such as rails. The components of the various embodiments of the attachment system are intended to provide a lightweight, rugged, reliable and durable stmcture for attaching the modules to the rails (or other stmcture) within the vehicle. The components may be made of any suitable material such as plastic (e.g. ABS, plastic, polycarbonate, polypropylene, etc.), metal (e.g. aluminum, steel, etc.) or other materials that provide the desired strength to retain the modules on the rails during all appropriate loading conditions and scenarios. The components of the attachment system may be formed by any suitable process such as molding (e.g. injection molding, etc.), stamping, forming, extrusion, etc.

[0043] It is important to note that the construction and arrangement of the elements of the various embodiments of the attachment system provided herein is illustrative only. Although only a few exemplary embodiments of the present inventions have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible in these embodiments (such as variations in rail and latch member configurations, shape and size and orientation of engagement stmcture, mounting arrangements, rotational and pivoting arrangements, use of colors, combinations of shapes, etc.) without materially departing from the novel teachings and advantages of the inventions. Further, the attachment system may be used in any type of veliicle such as tmcks, recreational vehicles, minivans, sport utility vehicles, passenger automobiles, etc. and at any suitable location within the vehicle (such as floors, cargo storage areas, etc.). Accordingly, all such modifications are intended to be witliin the scope of the invention as defined in the appended claims.
