It is provided an adjusting device for the longitudinal adjustment of a vehicle seat, comprising at least one rail for defining a longitudinal seat axis along which a seat base of the vehicle seat is adjustable, and for supporting at least one adjusting unit of the adjusting device, and at least two shiftably guided adjusting units arranged one behind the other along the longitudinal seat axis, to which the seat base is to be fixed in order to be adjustable along the longitudinal seat axis. The at least two adjusting units are adjustable relative to each other along the longitudinal seat axis, and each adjusting unit is assigned a separate drive for the power-operated adjustment along the longitudinal seat axis.

A relaxation comfort seat for a vehicle is equipped with a mechanism for realizing a relaxation comfort mode to enable an occupant to take a relaxed comfortable posture for providing comfort and stability to the occupant. In addition, even in a state in which a height of the seat is increased according to a body shape of the occupant, it is possible to easily realize the relaxation comfort mode of the seat.

A rear seat for a vehicle is provided, in which when the seat back is reclined. The angle of the seat cushion is adjusted by following the operation of the seat back to provide an optimal posture for fatigue reduction of a passenger. When the seat back is folded, the seat cushion is not operated.

A linear actuator for adjusting a seat component of a motor vehicle seat includes a lead screw having a rod head. A fastening means is connected to the rod head and connectable to a first seat component of the motor vehicle seat. The first seat component has a bearing, with the fastening means being insertable into the bearing in a first orientation and lockable in the bearing in a second orientation.

A lifting device for raising and lowering a cushion frame of a vehicle seat includes: a lifter link configured to be rotationally displaced to thereby raise or lower the cushion frame; a swing link configured to transmit a force for rotating the lifter link to the lifter link; a screw rod rotatably coupled to the swing link; a driving device configured to displace the screw rod along a first axis; and a first restricting portion configured to restrict displacement of a coupling portion between the swing link and the screw rod beyond a predetermined dimension in a second axis.

The invention relates to an apparatus for adjusting a seat position for a vehicle seat, which comprises at least one support element for a seat part and can be connected to a seat substructure, wherein the apparatus comprises at least one first limb and at least one second limb, wherein the limbs can be rotatably arranged on the seat substructure and the at least one support element, wherein a first angle α between the first limb and the support element can be adjusted by an angle adjustment device, wherein the at least one first limb and the at least one second limb each have a lever portion, and these are mechanically coupled, and wherein a change in the angle α causes a displacement of the at least one support element along a height axis Z, and a change in an angle of inclination θ of the support element.

The present disclosure provides a seat control system for a vehicle, which may sense whether passengers have been seated on a front seat and a rear seat, and easily implement sleep and rest postures of the front seat and the rear seat through the height adjustment, the reclining adjustment, and the like of the front seat and the rear seat according to the sensed result.

A rear seat for a vehicle is provided, in which when the seat back is reclined. The angle of the seat cushion is adjusted by following the operation of the seat back to provide an optimal posture for fatigue reduction of a passenger. When the seat back is folded, the seat cushion is not operated.
