Abstract
Description
- This patent application relates to U.S. Ser. No. 60/175,076, filed Jan. 7, 2000.
- 1. Field of the Invention
- The present invention generally pertains to motor vehicles. More particularly, the present invention pertains to a vehicle seat assembly. More specifically, but without restriction to the particular embodiment and/or use which is shown and described for purposes of illustration, the present invention relates to a rear seat assembly for a motor vehicle including a portion longitudinally translatable under a source of power.
- 2. Discussion
- Within a motor vehicle including multiple rows of seats, it is often desirable to transport people or cargo in various configurations. In particular, small children and infants are often transported in a center, rear seat position, because the center, rear seat position is frequently recommended based on safety considerations. In general, to accommodate different configurations for transporting people or cargo, vehicle seats are often translatable in the fore-aft direction of the vehicle. Middle and rear rows of seats, however, typically do not provide for the translation of the center seat portion independent of adjacent seats. In order to address situations where this is desirable, various designs have been proposed.
- For example, U.S. Pat. No. 6,135,529 discloses a center console, rather than a seat, that is adapted to store various items and is translatable between the center position of the rear row of seats and the center position of the front row of seats. The center console disclosed, however, is not adapted to retain a child or a child seat, and fully translates into the front portion of the vehicle, which is more dangerous for children because of airbags and other safety considerations.
- U.S. Pat. No. 5,951,084 discloses a center seat that is fore-aft slidable between the front row and a rear row of seats. The center seat is adapted to transport a person and includes a console box adapted to retain beverages or other items. The center seat disclosed, however, fully translates into the more dangerous front row of the vehicle, which does not comport with safety considerations for children.
- U.S. Pat. No. 5,611,589 discloses a vehicle having three rows of seats, and a center seat slidably mounted on a rail extending between the center portion of the middle and rear row of seats. The center seat is adapted to provide a variety of seat arrangements by translating into the middle or rear row of seats. The center seat, however, does not translate forward of the middle row of seats to provide occupants in the front row improved access to a child or items retained in the center seat.
- Location of a small child or infant in a standard center seat position, or one that does not translate forward of the middle or rear row of seats, renders access to the child by adults in a front row seat difficult if not impossible. Access is further complicated where the small child or infant is being transported in a rearwardly facing child seat. In order to generally improve access by those in the front row seat of a vehicle and to provide variable seat arrangements within a vehicle, various seat structures and designs have been developed.
- It is a general object of the present invention to provide a rear seat assembly for a motor vehicle including a portion translatable under a source of power in a fore direction and an aft direction.
- In one form, the present invention provides a motor vehicle including a passenger compartment having a floor. The motor vehicle has a front row of seats and a rear row of seats. The front row of seats is disposed in a forward portion of the passenger compartment and is interconnected to the floor. The rear row of seats is disposed in a rear portion of the passenger compartment, behind the front row of seats, and is interconnected to the floor. The rear row of seats includes a seat assembly having at least a portion linearly translatable in a fore direction and an aft direction under a source of power. In an alternative aspect of the invention, the portion translatable includes an integrated child safety seat. A switch assembly is located in the forward portion of the passenger compartment for selectively controlling linear translation of the portion of the seat assembly in the fore and aft directions.
- In another form, the present invention provides a motor vehicle seat assembly kit. The kit includes a seat assembly having at least a portion linearly translatable in a fore direction and an aft direction under a source of power. A switch assembly is adapted to be located in the forward portion of the passenger compartment for selectively controlling linear translation of the portion of the seat assembly in the fore and aft directions.
- In yet another form, the present invention provides a motor vehicle seat having a selectively translatable child safety seat attached thereto. The child safety seat includes a seat portion linearly translatable in a fore direction and an aft direction under a source of power. A switch assembly is also located in the forward portion of the passenger compartment for selectively controlling linear translation of the seat portion of the child safety seat in the fore and aft directions.
- Additional benefits and advantages of the present invention will become apparent to those skilled in the art to which this invention relates from a reading of the subsequent description of the preferred embodiment and the appended claims, taken in conjunction with the accompanying drawings.

Various types of mounting arrangements are known in the art for adjustably interconnecting thecentral seat segment 24 to thefloor 19. One suitablepower slide mechanism 25 is commercially available for front seat applications in vehicles sold by DaimlerChrysler Corporation, such as the 300M. - The
central seat segment 24 is independently translatable between an aft position and a fore position. The aft position is shown in FIG. 2A. The fore position is shown in FIG. 2B. In the aft position, thecentral seat segment 24 is rearwardly positioned so as to provide sufficient space between the front and rear rows of seats to facilitate ingress and egress for rear seat occupants. In the fore position, an infant or small child positioned on thecentral seat segment 24 can be more easily accessed by an adult from the front rows of seats, for example when the vehicle 12 is at rest but the adults in the front rows of seats remain belted. - The power slide mechanism of the
central seat segment 24 is powered by thevehicle battery 30 in a conventional manner. In the embodiment illustrated, translation of thecentral seat segment 24 is selectively controlled by a remotely positionedswitch assembly 32. As shown, theswitch assembly 32 is disposed on aconsole 34 located in the forward portion of thepassenger compartment 14 between the driver's and passenger'sseats switch assembly 32 can be mounted in various other positions accessible by one or both of the front seat occupants. Movement of theswitch assembly 32 in a first direction operates to translate thecentral seat segment 24 in the fore direction A. Conversely, movement ofswitch assembly 32 in a second direction operates to translate thecentral seat segment 24 in the aft direction. - Optionally, the
switch assembly 32 may include a plurality of preset seat position selectors (not shown) for selectively controlling linear translation of the central seat to preset fore and aft positions. For example, it may be desirable to include a full forward position preset selector switch and a full aft position preset selector switch. These switches would allow an operator to simply activate the full forward position preset selector switch in order to gain the most access to a child retained in the central seat, or to simply activate the full aft position preset selector switch to gain the most amount of ingress and egress to adjacent seats. Additional preset selector switches may be included to translate the central seat to desired intermediate positions. The preset selector switches may also be programmable by an operator, thus allowing the operator to quickly translate the central seat to a frequently used position. - In one question, the vehicle12 includes a
controller 33 for automatically translating thecentral seat segment 24 to the aft position in response to a predetermined vehicle condition. For example, the controller may be in operation to translate thecentral seat segment 24 to the aft position when the transmission is shifted out of a park mode. In such a manner, thecentral seat segment 24 would default to the rear or aft position during vehicle operation. - Referring now to FIG. 4, a second preferred embodiment of the seat assembly constructed in accordance with the teachings of the present invention is generally identified at110. The second preferred embodiment includes all aspects and preferences of the first preferred embodiment except as specified herein.
