Abstract
A gear stage (10), in particular of a vehicle seat (3), is embodied as a friction wheel gear stage. The gear stage (10) includes a housing (5), a drive (12), an output (14) that is set off from the drive (12) by an excentricity (e) and at least one sphere or another rolling body (15) for the transmission of force between the drive (12) and t he output (14). According to the invention, the position of the excentricity (e) relative to the housing (5) is arranged in a spatially fixed manner and the gear stage has at least two different direction-dependent and/or shiftable gear ratios.
Claims25
A gear stage of a vehicle seat, the gear stage being a friction wheel gear stage comprising:
- a housing;
- at least a drive input;
- at least one drive output spaced apart from the drive input by an eccentricity;
- and
- at least one ball or some other rolling body for transmitting force between the drive input and drive output, a position of the eccentricity with respect to the housing is being spatially fixed and the gear stage having at least two different, direction-dependent or switchable transmission ratios.
19-24. (canceled)
An actuating drive comprising:
- a housing;
- a drive input;
- a drive output spaced apart from the drive input by an eccentricity;
- a rolling body provided for transmitting force between the drive input and drive output to form a friction wheel first gear stage, a position of the eccentricity with respect to the housing being spatially fixed and the first gear stage having at least two different, direction-dependent or switchable transmission ratios;
- and
- a second gear stage.
