A power adjuster (30) for adjusting the position of an upper track (16) relative to a lower track (18) of a seat track assembly (10). The power adjuster includes a lead screw (22) fixedly secured to the upper track, a drive assembly (32) operatively coupled to the upper track and selectively coupled to the lead screw, a driven assembly (34) operatively coupled to the lead screw and selectively coupled to the drive assembly, and a release mechanism (36) coupled to the upper track. The release mechanism is operable between a locked condition coupling the driven assembly to the drive assembly and the upper track wherein the driven assembly and the drive assembly move longitudinally along the lead screw with the upper track relative to the lower track and an unlocked condition wherein the driven assembly is decoupled from the upper track and retained along the lead screw during movement of the upper track relative to the lower track.

Provided is a vehicle seat having a pitching function, which not only has an assist function for bringing a main frame to a seated position or a forward tilted position, but also prevents the increase in the width and the increase in the weight of the seat. The vehicle seat includes: a base frame; a main frame disposed on the base frame and having a back frame and a cushion frame; and a link mechanism that allows the main frame to swing to the seated position and the forward tilted position with respect to the base frame. A third rotating shaft of the link mechanism is provided with a torsion spring that urges the main frame to swing from the forward tilted position to the seated position.

A seat assembly secured to a floor in an automotive vehicle has a seat cushion, a seat back, a seat track assembly, a latch mechanism, a memory mechanism, and an interlock assembly. The seat back is operatively coupled to the seat cushion, and is movable between an upright position and a folded position. The seat track assembly includes a fixed track adapted to be fixedly secured to the floor and a movable track fixedly secured to the seat cushion. The movable track is slidably coupled to the fixed track. The latch mechanism is operatively coupled between the fixed and movable tracks. The latch mechanism prevents sliding movement of the movable track, and is (17) selectively unlocked from the fixed track to allow sliding movement of the seat cushion between a plurality of positions. The memory mechanism is operable between a home position and a memory position. In the home position, the memory mechanism is coupled and moves with the movable track. In the memory position, the memory mechanism is coupled with the fixed track and defines a previously selected one of the plurality of positions. The interlock assembly comprises a hook lever, an interlock lever, and a cable. The hook lever is pivotally connected to the seat cushion. The interlock lever is pivotally coupled to the movable track for movement between a disengaged position and an engaged position. The cable is operatively coupled between the hook lever and the interlock lever, and is configured for moving the hook lever into and out of engagement with the seat back. Moving the seat back to the folded position actuates the memory mechanism to the memory position, which unlocks the latch mechanism from the fixed track to allow sliding movement of the seat cushion in a first direction away from the previously selected one of the plurality of positions to the easy-entry position. Actuation of the memory mechanism to the memory position also allows the interlock lever to rotate into the engaged position to cause the cable to move the hook lever into engagement with the seat back to maintain the seat back in the folded position.

A vehicle seating assembly is provided that includes a seat rotatable about an axis of rotation disposed at a front of the seat between a sitting position and a standing position, a latch assembly rotatably coupled to the rear of the seat and releasably coupled to a track assembly disposed below the seat, wherein if the seat is in a sitting position, the latch assembly is in a locked position relative to the track assembly, and wherein if the seat is in a standing position, the latch assembly is in an unlocked position relative to the track assembly, and a connecting bar extending through the latch assembly, wherein the latch assembly is rotatable around the connecting bar as the seat moves between the sitting position and the standing position.

A memory module includes a pressure tongue rotatably mounted on a fixed block through a reset spring providing a first driving force for rotation of the pressure tongue. A rotating block is rotatably mounted on a slider through a torsion spring providing a second driving force for rotation of the rotating block, and the slider is slidably mounted on a guide rail. When the rotating block projects forwards under the action of the second driving force, a locking block is inserted into a locking hole, and an upper retaining surface is separated from a first lower retaining point. When the pressure tonguepresses the rotating block downwards under the action of the first driving force to overcome the second driving force to force the rotating block to raise backwards, the locking block is separated from the locking hole, and the upper retaining surface is contact with the first lower retaining point.

Disclosed is a vehicle seat adjustment device including a seat-cushion-tilting frame disposed on a moving rail, the moving rail being coupled to a fixed rail so as to be movable forwards and backwards, and connected to a seatback frame, a tilting device hingedly coupled to a base bracket on the moving rail and to a rear end of the seat-cushion-tilting frame to perform forward tilting of the seat-cushion-tilting frame, a locking device connected to the tilting device to lock and unlock the tilting device, and a probe rotatably disposed between the seatback frame and the tilting device, the probe including a stopper capable of being inserted into a locking groove formed in the seatback frame. Rotation of the probe is restricted when the stopper is inserted into the locking groove.

The present disclosure relates to a vehicle seat with a frame formed by a seating portion and a back rest, upper rails longitudinally adjustable on lower rails and lockable by means of a longitudinal rail locking mechanism, a coupling system for adjustment of the frame in relation to the upper rails, said coupling system comprising a coupling member with a coupling member pivot axis, a seat locking mechanism for locking the vehicle seat in an upright seating position, where said frame, upon operation of an easy entry actuator and unlocking of the seat locking mechanism, can be tilted forward starting from the upright seating position.

A vehicle seating assembly is provided that includes a pivot bracket coupled to a vehicle floor and disposed at a front of a seat frame, a gear assembly and a locking disk assembly disposed around an axis of rotation defined by the pivot bracket, wherein the gear assembly and the locking disk assembly are configured to each alternatively move the seating assembly from a sitting position to a standing position, and a track assembly disposed on the vehicle floor and between opposing side brackets of a seat frame. The track assembly includes a cam assembly movable between a locked position and an unlocked position. The vehicle seating assembly further includes a crank assembly extending between the pivot bracket and the cam assembly and configured to move the cam assembly from the locked position to the unlocked position.
