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.
