The invention relates to a device for adjusting a seat position for a vehicle seat, wherein the device comprises at least one support element for a seat part and can be connected to a seat substructure, wherein the device comprises at least one first leg and at least one second leg, the legs being rotatably arranged on the seat substructure and the at least one support element, wherein a first angle α can be adjusted between the first leg and the support element by means of an angle adjustment device, wherein the at least one first leg and the at least one second leg are mechanically coupled, wherein a change of the angle α causes a displacement of the at least one support element along a height axis Z and along a longitudinal axis X.

The invention relates to a device 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, the device comprising at least one first leg and at least one second leg, the legs being rotatably arrangeable on the seat substructure and the at least one support element, the at least one first leg and the at least one second leg being mechanically coupled by a connecting element, the length of which can be modified, wherein a modification of the length of the connecting element causes a change in an angle of inclination θ of the support element.

A seat apparatus for a vehicle is provided, wherein a base bracket and a moving bracket are mounted to a body floor to lift and lower a seat, and a seat track is mounted to the moving bracket to move the seat in forward and rearward directions, so that the seat is moved and lifted and lowered. Accordingly, since the lifting/lowering structure of the seat is mounted to the body floor, space is secured below the seat, so indoor atmosphere is improved due to the increase of the space efficiency.

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.

The present invention provides a horizontal instrument, a supporting device and a method for adjusting the bearing surface of the supporting device to be horizontal. The horizontal instrument in the present invention is used for maintaining a bearing surface parallel to a horizontal plane, wherein the horizontal instrument comprises a slide-swing assembly, and a monitoring assembly, when the monitoring assembly detects that the bearing surface is not parallel to the horizontal plane, the controller instructs the driving unit to drive the slider to slide, which leads the lower end of the swinging rod to slide, and then drives the swinging rod to swing, thereby, the upper end of the swinging rod drives the bearing surface to rotate for an angle so that the bearing surface is maintained parallel to the horizontal plane.

A seat assembly includes a base frame and first and second guide brackets coupled to opposed sides of the base frame. The first and second guide brackets each include slots disposed therethrough. First and second support brackets are slideably mounted to the slots of the first and second guide brackets, respectively. A seat portion includes a seat frame that is pivotally coupled to the first and second support brackets at opposed first and second ends of the seat frame. The seat frame is configured to pivot with respect to the first and second support brackets between use and upright non-use positions. The base frame is rotatably supported on a swivel mechanism for rotation of the seat assembly between forward-facing and rearward-facing configurations.

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 a vehicle seat with at least one laterally positioned operating device for operating the vehicle seat functions and/or vehicle functions and an adjustment device for adjusting a vertical position and/or an inclination of the at least one operating device with respect to a rest of the vehicle seat, wherein the adjustment device comprises a rotational axis extending in the seat width direction and a shaft which is connected to the operating device, positioned at a distance from the rotational axis and rotatable together with the operating device about the rotational axis, wherein the adjustment of the vertical position and/or of the inclination of the operating device is feasible by means of a rotational movement of a spindle element which is in operative contact with the shaft, wherein a central axis of the spindle element is perpendicular to a central axis of the shaft.

A device for adjusting a seat of a vehicle is capable of implementing functions including adjusting a position of the seat back and forth, a height of the seat up and down, and tilting or the like by using a plurality of actuators having pistons. The functions of adjusting the position of the seat back and forth, the height of the seat up and down, and tilting or the like are carried out by providing connections between a floor panel and a seat cushion frame through a plurality of actuators and a single link, and selectively moving a piston of each actuator back and forth.
