A height adjustment apparatus for a vehicle seat may include a pinion gear mounted in a side frame having a front portion and a rear portion are connected to a seat bracket by links; a rack gear engaged with a top end of the pinion gear and coupled with the seat bracket via an hinge, the rack gear moving according to driving of the pinion gear to raise and lower the side frame; and a play adjustment bracket for guiding up and down motion of the moving rack gear by providing repulsive force to a top portion of the rack gear, the play adjustment bracket being fixedly positioned by being fastened with a plurality of support pins provided in the pinion gear and the side frame.

A vehicle seat (11) includes a seat frame (22a) having an opening (46) in a plate-shaped part (43), andan actuator (31) mounted on the plate-shaped part (43). Accordingly, it is possible to provide a vehicle seat that further contributes to quietness in the interior of a vehicle.

The invention relates to a device for influencing a backward movement of a seat (1), in particular a backrest part (1.1) of the seat (1), with at least one deformation element (4) arranged in a hinged area (7) of the seating part (1.2) of the seat (1), the deformation element (4) being configured such that the deformation element can be deformed due to a force acting on the seating part (1.2) and/or the back part (1.1) at a predefined torque curve. The invention also relates to a seat (1), in particular a vehicle seat, comprising a seating part (1.2), a backrest part (1.1) and the type of device.

An adjustment mechanism for a seat, the adjustment mechanism permitting the seat to be adjusted along a motion path that provides adjustment of height and/or back inclination of the seat, the mechanism comprising: a base part; a side part for attaching to the seat; a forward link mounted between the base part and the side part such that the forward link can rotate with respect to both the base part and the side part; a rear link mounted to the base part at a first position, the rear link mounted between the base part and the side part such that the rear link can rotate with respect to both the base part and the side part; an adjustment link attached to the rear link at a second position such that the adjustment link and rear link move in unison; and an adjustable strut mounted between the side part and the adjustment link such that the adjustable strut can rotate with respect to both the side part and the adjustment link, the adjustable strut being mounted to the adjustment link at a third position remote from the second position and mounted to the side part at a fourth position, the adjustable strut having a length running between the third position and the fourth position, the length being changeable between a minimum length and a maximum length to move the seat along the motion path by rotation of the forward and rear links with respect to the base part and side part.

Aspects of the present disclosure include a vehicle having a passenger assistance system for facilitating ingress and egress of passengers. The vehicle may include a plurality of wheels. The vehicle may include a body including at least one doorway supported on the plurality of wheels via a suspension. The vehicle may include a door movable between an open position and a closed position covering the at least one doorway. The vehicle may include a first platform movable between a horizontal position beneath a bottom of the doorway and a stowed position parallel to the door. The vehicle may include an occupant compartment within the body. The occupant compartment may include a seat rotatable to face the doorway in an ingress or egress mode. The occupant compartment may include a robotic arm configured to extend along an ingress or egress path through the doorway.
