A vehicle seat has a seat base, a carriage, and an adjusting device. The adjusting device is formed in such a way that the vehicle seat is adjustable vertically or the inclination is adjustable by the adjusting device. The adjusting device has a rotation device arranged on the carriage such that the seat base is rotatable relative to the carriage about a vertical axis by the rotation device. The adjusting device includes a strut, a first end of which is pivotably attached to the carriage or to a rotation base fixed to the carriage and a second end of which is pivotably attached to the seat base. The adjusting device has first and second linear actuators. The seat base is supported on the first linear actuator, the second linear actuator, and/or the strut. The first and second linear actuators cooperate to adjust the vehicle seat.

A vehicle seat is provided with a wire that, in the event of a vehicle frontal collision, enables a pulling load applied by a vehicle occupant to a webbing to be transmitted between a cushion frame of a seat cushion and a movable rail of a sliding device. One end portion of the wire is anchored to a first anchoring member of the movable rail, while another end portion of the wire is anchored to a second anchoring member of the cushion frame.

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.

An assembly of a vehicle seat comprises a seat part assembly, a floor assembly, a front swivel element that is pivotally coupled to the seat part assembly at a front, upper pivot point, and a rear swivel element that is pivotally coupled to the seat part assembly at a rear, upper pivot point. A drive device includes a linear element and a transmission element operatively connected to the linear element. In a first end position, the linear element takes a first angle to an imaginary line extending through the front, upper pivot point and the rear, upper pivot point, and in a second end position takes a second angle to the line, in an intermediate position the linear element is arranged at a right angle to the line and exceeds the right angle when adjusted between the first end position and the second end position.

An embodiment is a seat height gear system including a monopost apparatus configured to be mounted under a seat, the monopost apparatus comprising a lower post and an upper post, and a direct drive motor apparatus within the monopost apparatus, the direct drive motor apparatus including a motor and a gear unit, the gear unit including a pinion and a rack bar, the rack bar being configured to be engaged with the pinion, the motor being fixed to the lower post of the monopost apparatus, the pinion being coupled to the motor, the rack bar being fixed to an upper post of the monopost apparatus, the motor being configured to rotate the pinion, and the rack bar being configured to convert the rotation of the pinion into the linear motion.

A vehicle seat comprises: a seat base; 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 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 rotatably coupled to the seat back assembly and rotatably coupled to the slider; a first lower seat lifting mechanism comprising a lifting bracket, wherein the lifting bracket is rotatably coupled to the first side member at a first end of the lifting bracket; and a second lower seat lifting mechanism comprising a bracket rotatably coupled to the base and a link arm rotatably coupled to the bracket and rotatably coupled to the slider.

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 suspension system (1), preferably a driver seat (1), comprising a first suspension part (10), preferably a frame (10) of the driver seat (1); a second suspension part (11), preferably a seat surface (11) of the driver seat (1), wherein the two suspension parts (10, 11) are movable relative to each other in at least one first spatial direction (Z), preferably in the vertical direction (Z); a kinematic system (12), preferably a scissor kinematic system (12) which is designed to connect the two suspension parts (10, 11) in a movable manner relative to each other at least in the first spatial direction (Z); a suspension device (13) which is designed to support the static load of the second suspension part (11); and an actuator (2) which is designed to introduce a force bidirectionally between the two suspension parts (10, 11) and thereby actively damp the relative movement between the two suspension parts (10, 11). The suspension system (1) is characterized in that the actuator (2) has a bearing (28), preferably a ball bearing (28), which is arranged within the power flow between the two suspension parts (10, 11) such that an axial load can be kept away from the driven axle of the actuator (2) at least partly, preferably completely.

A vehicle seat that includes a support intended to be rigidly fixed to the frame of a vehicle, a seating portion, a backrest extending the rear end of the seating portion, and a connecting mechanism which connects the seating portion to the support. The connecting mechanism has a primary mechanism which allows forward tilting of the seating portion and backrest relative to the support between a rest position and a forward-tilted position. The seat includes a first motor able to tilt the seating portion from its rest position to its tilted position, and a control member for the first motor.

A seat support assembly has a lower member with a first channel extending in a front-back direction of the seat support assembly and an upper member positioned above the lower member and having a second channel extending in the front-back direction. A first linkage has a lower end pivotably coupled to the lower member and translatable in the front-back direction by way of the first channel and an upper end pivotably coupled to the upper member. A second linkage has a lower end pivotably coupled to the lower member and an upper end pivotably coupled to the upper member and translatable in the front-back direction by way of the second channel. The first and second channels are offset from one another in the front-back direction.
