DEVICE FOR A MOTOR VEHICLE SEAT
First Claim
1. A drive device for a vehicle seat, the drive device comprising:
- a frame;
a drive input mounted on the frame so as to be pivotable about a first axis;
a drive output mounted on the frame so as to be rotatable about a second axis; and
a transmission means for transmitting a driving pivoting movement of the drive input, which causes the drive input to be moved from an initial position into a deflected position, to the drive output and for generating a rotational movement of the drive output, the transmission means comprising a rolling body which, in an initial position and during the driving pivoting movement of the drive input, is in frictional contact with and rolls on both the drive input and also at the same time the drive output, and which disengages during the pivoting movement back into the initial position.

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.

12. A motor vehicle seat comprising:
-
a geared fitting provided in one or more of a height adjuster, an inclination adjuster and a backrest adjuster of the vehicle seat; and a drive device connected to the geared fitting, the drive device comprising; a frame; a drive input mounted on the frame so as to be pivotable about a first axis; a drive output mounted on the frame so as to be rotatable about a second axis; and a transmission transmitting a driving pivoting movement of the drive input, from an initial position into a deflected position, to the drive output and generating a rotational movement of the drive output, the transmission comprising a rolling body in frictional contact with and rolling on both the drive input and the drive output, and which disengages during pivoting movement back into the initial position. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
