Abstract: An adjustable memory track assembly for a vehicle seat has a lower rail (18) adapted to be secured relative to a vehicle frame, and an upper rail (20) adapted to support the seat for fore/aft sliding movement relative to the lower rail (18). The adjustable memory track assembly (24) also has a track lock assembly (24) operable via a first actuator (28) between a locked, engaged state wherein relative movement between the lower (18) and upper rails (20) is resisted, and an unlocked, disengaged state wherein the seat can be slid to and then locked in a user-selected position. The adjustable memory track assembly (24) is characterized in that the memory module (24) is provided with a blocking element to prevent rearward movement of the seat past the user-selected position independent of the locking state of the track lock assembly (24).

Abstract: A seat adjustment apparatus comprises a first rail (24) and a second rail (26) each having a plurality of openings that extend along a longitudinal axis, the openings being defined by spaced-apart locking surfaces. A locking mechanism having first (56) and second (58) locking portions is configured to engage the first and second rails. The first (56) and second (58) locking portions are selectively rotatable between a released position and a locked position. In the locked position, the first and second locking portions are configured for relative axial movement along the longitudinal axis such that the interaction of the first and second locking portions of the locking mechanism with the spaced-apart locking surfaces of the openings of the first and second rails attenuates longitudinal freeplay therebetween.

Abstract: An adjustable memory track assembly for a vehicle seat has a lower rail adapted to be secured relative to a vehicle frame, and an upper rail adapted to support the seat for fore/aft sliding movement relative to the lower rail. The adjustable memory track assembly also has a track lock assembly operable via a first actuator between a locked, engaged state wherein relative movement between the lower and upper rails is resisted, and an unlocked, disengaged state wherein the seat can be slid to and then locked in a user-selected position. A memory module is operable via a second actuator to record the user-selected position. The second actuator is also operatively connected to disengage the track lock assembly to allow forward movement of the seat from the user-selected location to a forward location, and thereafter allow rearward movement of the seat back to, but not past, the user-selected location.

Abstract: A seat assembly having a recliner mechanism and a memory module. The recliner mechanism facilitates pivotal movement of a seat back. The memory module controls operation of the recliner mechanism.

Abstract: A vehicle seat track assembly includes a first track having first and second spaced apart walls. Each of the first and second walls include a plurality of openings formed therein. A second track is slidably mounted relative to the first track. The vehicle seat track assembly further has a locking mechanism including a first pin carried by the second track and slidably movable between an engaged position such that the first pin extends through one of the plurality of openings formed in the first wall of the first track and a disengaged position such that the first pin is retracted from the plurality of openings formed in the first wall of the first track. A second pin is carried by the second track and is slidably movable between an engaged position such that the second pin extends through one of the plurality of openings formed in the second wall of the first track and a disengaged position such that the second pin is retracted from the plurality of openings formed in the second wall of the first track.

Abstract: A longitudinal seat adjustment apparatus for a vehicle seat includes a first seat support member that is attachable to a vehicle. A second seat support member that is movable with respect to the first seat support member and configured to support the seat such that the seat is movable with the second seat support member is also provided. A locking member that is movable generally vertically with respect to the first and second seat support members between a locked position and an unlocked position for locking and unlocking the second seat support member with respect to the first seat support member is additionally provided. The locking member is a substantially planar two-part locking member and includes a first part generally horizontally movable with respect to a second part.

Abstract: A longitudinal seat adjustment apparatus for a vehicle seat includes a first support member that is attachable to a vehicle, and a second support member that is moveable with respect to the first support member and configured to support the seat such that the seat is movable with the second support member. One of the support members has first and second lock portions that face each other, and the other support member has a third lock portion that is configured to be located between the first and second lock portions. The apparatus further includes a locking member that is movable generally vertically with respect to the support members between a locked position and an unlocked position for locking and unlocking the second support member with respect to the first support member. When the locking member is in the locked position, the locking member extends into the first, second and third lock portions.

Abstract: An automobile seat includes seat frame and backrest frame portions, each of which includes a pair of opposite side braces of generally U-shaped configuration which face away from the seating surfaces of their respective side frame and back rest frame portions. The side braces of the side frame and back frame portions define open channel-like areas for accommodating adjusting units of the seat.

Abstract: An actuating device for controlling the operation of a vehicle seat includes a central block movable about a central block shaft in four different directions to execute four distinct adjustment functions. A handle housing is mounted on a shaft perpendicular to the central block shaft. The handle housing is rotatable in fifth and sixth directions to execute distinct fifth and sixth adjustment functions.

Abstract: An air-sprung vehicle seat includes an air spring and a scissors linkage which are operative for adjusting the vertical height of the seat. The vehicle seat also includes a locking device for adjustably fixing the vertical height of the seat, the locking device including a fixing element which is articulated to the scissors linkage and a fixing device which is engageable with the fixing element for fixing the relative position thereof in the seat. The seat also includes a non-return valve which is responsive to actuation of the fixing device for controlling the admission of compressed air into and the escape of compressed air from the air spring.

Abstract: The invention concerns a vehicle seat having pneumatic suspension with automatic regulation of the seat height and an integrated height adjustment system. The height adjustment is designed in such a way that it can be used, even in the rest position of the vehicle seat, for the direct and precise setting of the selected static height of the seat. There is provided that, during the adjustment of the static height, tappet stops of control member are changed in such a way that during the adjustment process they render the valve tappets substantially free from play.
