Abstract
A vehicle seat having a drive device for driving a adjustment kinematics of the vehicle seat may have an adjustment arm, and a tensioning device. The drive device may have a pinion which can be rotated about a pinion rotation axis and which is in toothed engagement with a tooth segment of the adjustment arm. The tensioning device pretensions the adjustment arm so that the tooth segment is pretensioned in the direction of the pinion. The tensioning device has at least one sliding element which is in abutment with the adjustment arm. During an actuation of the height adjustment kinematics, the at least one sliding element slides along the adjustment arm. The sliding element is resiliently pretensioned by a resilient element.
