A displacing device (28, 29) having a rotary actuator (8) and a gearing is used for displacing a component (17) of a seat (14), particularly of a seat (14) in a motor vehicle. The gearing consists of a planetary gearing with a central wheel (7), which is driven by the rotary actuator (8), of at least one planet wheel (4) rotationally mounted on a planet carrier (6), and of a fixed ring gear (1). The at least one planet wheel (4) meshes with the central wheel (7) and the ring gear (1). The output of the gearing ensues via the planet carrier (6) that is provided, in particular, in the form of a cable drum, in order to displace the component of the seat by means of a sheathed cable that is fixed on said cable drum and can be wound thereon. This type of gearing makes it possible to obtain a particularly small overall size thereby significantly facilitating the installation of the displacing device (28, 29) in a seat (14). |
