FITTING FOR AN ADJUSTMENT DEVICE OF A MOTOR VEHICLE SEAT

摘要

A fitting (1) for an adjustment device, in particular inclination adjustment of a motor vehicle seat, includes a fitting upper part (2) having a first internal toothing (4), a fitting lower part (3) which is adjustable relative to the fitting upper part about a fitting axis and has a second internal toothing (5) arranged coaxially with respect to the first internal toothing, at least two, preferably, three, rotatably arranged planet gears (7) which are in engagement with the first and second internal toothings, and a drive shaft (6) which is in operative connection with the at least two planet gears by means of a pinion (23). Noise loads and buckling effects are avoided even after a relatively long period of operation, with a spring element (11) prestressing the planet gears (7) in the direction of the axis of rotation onto the fitting lower part (3) or fitting upper part (2).
