  • Patent number: 8579377
    Abstract: A drive device for a motor vehicle seat (1) has a mount (22), a drive (24) which is mounted to the mount (22), so as to be pivoted about a first axis (A), an output (25) which is mounted to the mount (22), so as to be rotated about a second axis (B), and a transmission. The transmission transmits a driving pivot movement of the drive (24), which moves the drive (24) from an initial position into a deflected position, to the output (25) and causes a rotating movement of the output (25). At least one rolling body (26) is provided as the transmission. The rolling body (26), in the initial position and during the driving pivot movement of the drive (24), is in friction contact both with the drive (24) and simultaneously with the output (25) and rolls along same, and releases during the pivot movement back into the initial position.
