Abstract: A support inclination device for a seat face of a vehicle seat may have a drive unit and a support which is bent multiple times and is designed as an inclination support, the latter on one side being rotatably mounted without play, and on the other side being rotatably mounted with play on a bracket and by way of the bracket being coupled to the drive unit for inclination adjustment. A seat part and a vehicle seat with the device are also provided.

Abstract: A protection module for limiting and/or blocking a movement between at least two structural parts and/or a seat function of a vehicle seat in the event of a crash or during normal use may have one control unit, one protection unit and one coupling element arranged between the control unit and the protection unit. The coupling element may be formed to be variable in its length and couples the control unit and the protection unit to one another in such a way that a movement of the control unit can be transmitted to the protection unit. An adjustable vehicle seat may use the protection module.

Abstract: A vehicle seat may have height-adjustment kinematics where the kinematics may have a four-joint arrangement and an adjustment arm. The four-joint arrangements may have a base, a side part, a front swing arm and a rear swing arm as transmission elements of the four-joint arrangement. A first revolute joint may connect the base in a pivotable manner to the rear swing arm, a second revolute joint may connect the rear swing arm in a pivotable manner to the side part, a third revolute joint may connect the side part in a pivotable manner to the front swing arm, and a fourth revolute joint may connect the front swing arm in a pivotable manner to the base. Each of the two four-joint arrangements can be adjusted by one of the two adjustment arms, and a drive device, having exactly one transmission motor, drives the two adjustment arms.
