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...

Abstract

The present invention relates to an adjustment device (1) for carrying out at least one adjustment function, in particular for adjusting a motor vehicle seat, having a planetary gear mechanism (A) which has a drive and an output (25), and a brake device (B) which keeps torques acting on the planetary gear mechanism (A) largely away from the output (25), wherein the planetary gear mechanism (A) hasa planet carrier (9) which is also part of the brake device (B).

Description

technical field [0001] The invention relates to an adjusting device, in particular for a vehicle seat, for carrying out at least one adjusting function, the adjusting device having a planetary gear with a drive (Antrieb) and a braking device. Output shaft (Abtrieb), the braking device prevents as much as possible the torque acting on the planetary gear from the output shaft. Background technique [0002] Such adjustment devices are known, for example, from US 4,211,451, DE 3201309 and US 2005 / 0245348 A1 and are suitable, for example, for electric or preferably manual drive of a device for adjusting the height of a motor vehicle seat. In this regard, the adjusting device converts the input drive torque into a higher output torque for angular adjustment of components connected thereto, such as the seat height adjuster. At least in order to reduce the torque acting on the planetary gear from the drive unit, the adjusting device includes a braking device. However, the adjustin...
