Patent ID: 8579377

Claim:
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 first 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 from said rolling body during pivoting movement back into the initial position, said transmission means further comprising a second rolling body which, in the initial position, is in frictional contact both with the drive input and simultaneously also with the drive output, and which, during the driving pivoting movement of the drive input, is driven along, with the simultaneous frictional contact being eliminated, by a driver of the drive input.
