Motorgetriebene Vorrichtung zur Verstellung eines Satzes von Elementen, insbesondere der verstellbaren Teile eines Fahrzeugsitzes.

摘要

This device comprises a motor (1), the output shaft (2) of which carries two coaxial worms (5, 6), offset axially and with opposite pitches, two pairs of wheels, (7, 9, 8, 11) meshing with the worms, mutually in pairs, at the rate of two wheels (7, 8; 9, 11) per worm, which wheels are arranged on either side of the worms, an output shaft (12, 13, 14, 15) traversing each wheel (7, 8; 9, 11) freely and intended to control an associated element at one or other of its opposite ends, and on each shaft (12 . . . 15) and facing each wheel (7 . . . 11), a clutch (E1, E2, E3, E4) independent of the other clutches and adapted in order to be able to link the selected shaft in rotation to the corresponding wheel. This arrangement makes it possible to produce a compact control assembly distributing, from a single location, multiple functions from a lightweight divider box ensuring the switching of the functions, with a reduced overall size and a simplified single connection.
