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 2It 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 shaft...

Abstract

An adjustment device is disclosed for carrying out at least one adjustment function, such as for a motor vehicle seat. The device includes a drive in the form of a planetary gear mechanism. The mechanism has a planet carrier and an output. The output is stopped by a brake device when the drive is not actuated. The planet carrier cooperates with the brake device to release the brake device.

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 32 01 309 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 adjust...
