System including a vehicle seat comprising a seating portion, a backrest pivotally mounted on the seat by a lockable hinge mechanism, the seat further comprising a motorized adjustment device connected to the backrest independently of the hinge mechanism. An electric control device synchronously controls the hinge mechanism and the motorized adjustment device.

A vehicle seat comprising: seatback; a seat bottom mounted pivoting relative to the seatback and a track comprising a fixed element and a mobile element moveable relative to the fixed element. The seat bottom pivots relative to the mobile element of the track. The seatback slides relative to the fixed element of the track. The seatback pivots relative to the fixed element of the track, around the mobile transverse axis. A stop limits the movement of the seatback. The seat bottom is shaped for pulling on the seatback and causing the rotation of the seatback, in case of movement of the mobile element of the track relative to the fixed part once the stop blocks the movement of the seatback.

A seat assembly includes a five-bar linkage for moving the seat assembly between a plurality of positions in an automotive vehicle. A first link is rotatably coupled to a seat back at a second pivot point disposed coaxial to a first pivot point, and to a seat base defining a fifth link at a third pivot point. A second link extends axially between the first and second pivot points. A third link is defined by a lower seat back portion and a seat cushion and extends between the first pivot point and a fifth pivot point disposed adjacent a front portion of the seat cushion. A fourth link is rotatably coupled to the third link at the fifth pivot point and the seat base at a fourth pivot point. The seat assembly is capable of moving to both a pitched easy entry position and a stow flat to floor position.

Adjustable seat device for a vehicle, comprising: -a base portion (10), -a seat portion (20) that is movable with respect to the base portion (10) between a first position, referred to as retracted, and a second position, referred to as extended, -an articulation system (30) forming a deformable parallelogram, which is connected to the base portion (10) and to the seat portion (20) and comprises at least one diagonal support arm (31) connected diagonally to the deformable parallelogram, characterized in that the diagonal support arm (31) is designed to have a first length when the seat portion (20) is in the first position and a second length when the seat portion (20) is in the second position.

A vehicle seating assembly includes a frame movable between a sitting position and a standing position and pivotably coupled to a vehicle floor at a pivotable coupling defining a first axis of rotation. The vehicle seating assembly has a pivot bracket coupled to the vehicle floor, a linkage assembly with a link extending between the pivot bracket and the frame, and a shaft extending through the pivot bracket and the link in a direction transverse to the link, and defining a second axis of rotation. The vehicle assembly also includes a gear assembly with a sector gear and a pinion gear operable to move the sector gear from a first position to a second position, and a pawl assembly coupled to the sector gear and selectively engageable with the shaft to position the shaft in fixed and unfixed positions.

A lift mechanism for a vehicle seating assembly comprises a gear assembly that includes a first gear and a second gear. A mounting bracket is fixedly coupled to a vehicle and shares a common axis with the first gear, wherein the first and second gears are positionable in a fixedly coupled arrangement at an initial location relative to the mounting bracket or at a final location relative to the mounting bracket, such that, when the first and second gears are in the fixedly coupled arrangement at the initial location relative to the mounting bracket, the seating assembly is in a sitting position, and when the first and second gears are in the fixedly coupled arrangement at the final location relative to the mounting bracket, the seating assembly is in a standing position.

A vehicle seat is provided having a track assembly to allow a seat bottom to slide in a fore-aft direction. A lock assembly is connected to the track assembly and moveable between a locked status and an unlocked status, wherein in the locked status the seat bottom is prevented from sliding, and in the unlocked status, the seat bottom is allowed to slide. A seatback is pivotally connected to the seat bottom. When the seatback is pivoted forward to a first inclined position, the seatback engages and moves the lock assembly to the unlocked status. In the unlocked status, the seat bottom is biased to slide rearward to a rear storage position. In the rear storage position, the lock assembly is moved to the locked status.

A vehicle seat comprising a seat back with a seat back frame, a seat cushion with a seat cushion frame and one first and second links. The first link is mounted pivoting relative to the seat cushion frame around a first transverse axis, and relative to a seat support around a second transverse axis. The second link is mounted pivoting relative to the seat cushion frame around a third transverse axis, and relative to a seat support around a fourth transverse axis. The first and second links are configured in order to allow lifting a rear part of the seat cushion frame relative to said seat support.

A vehicle seat device includes a seat cushion having a cushion front side and cushion rear side both running in the transverse direction of the seat device. The device also includes a seat back having two backrest edge sides opposite each other and each running in the transverse direction of the seat device. The seat back is arrangeable on the cushion front and rear sides of the seat cushion in order to change a seat direction. The seat back is mounted so as to be rotatable by at least 180° around a transverse axis in order to change the seat direction. At least one headrest unit is arranged on the seat back in a displaceable manner in such a way that it can be displaced beyond the backrest edge side facing away from the seat cushion in each case and can be displaced back under this backrest edge side.

Various vehicle seat improvements are enabled herein. For instance, a kinematic seat for a vehicle comprises a seat base connected to the vehicle. A first side member is affixed to a base at a first side of the base. A second side member is affixed to the base at a second side of the base, opposite the first side of the base. A slider is slidably received in the base. A seat back assembly is rotatably coupled to the first side member and rotatably coupled to the second side member. A linkage is rotatably coupled to the seat back assembly and rotatably coupled to the slider, whereby sliding of the slider rotates the seat back assembly. A first lower seat lifting mechanism comprises a lifting bracket, wherein the lifting bracket is rotatably coupled to the first side member at a first end of the lifting bracket, and wherein the lifting bracket is slidably received in a channel of the first side member at a second end of the lifting bracket. A second lower seat lifting mechanism comprises a bracket rotatably coupled to the base and a link arm rotatably coupled to the bracket and rotatably coupled to the slider.
