Embodiment Construction
[0046] The adjusting device 1 exemplified and schematically shown in the drawings comprises a ribbed housing 2 , for example made of plastic 2 , from which a drive shaft 3 provided with fine gear teeth and mounted in the housing 2 drives from the housing 2 protrude( figure 1 ). A handwheel for manual actuation of the adjusting device 1 can then be attached to the tooth, or a motor can be attached to the tooth. The housing 2 further comprises holes 4 for fixing the adjustment device 1 eg to a lateral support of the metal structure of the seat part.
[0047] Such as figure 2 It can be seen that the housing 2 is provided on the inside with an inner gear 5 extending coaxially with the drive shaft 3 , in which three planetary gears 6 rotate around the outer gear 7 of the drive shaft 3 inserted into the housing 2 . Thus, as the drive shaft 3 turns, the axes 8 of the planet gears 6 travel on circular orbits in the housing 2 at a lower rotational speed relative to the drive shaf...
