Embodiment Construction

[0031] figure 1 and 2 Assembled and exploded views of a particularly preferred embodiment transmission mechanism and its components are shown. The integral transmission mechanism housing 1 is used to receive the worm 3 and the worm wheel 4 . Preferably, the mechanism is closed from below by a housing closure 2 or a housing cover.

[0032] The transmission housing 1 comprises an upper part 10 , in the lower corner region of which downwardly forms legs 11 or bridges. Since the assembled transmission can ultimately be used in any spatial orientation of the drive, the upper and lower spatial orientations are mainly used only for visual description.

[0033]For mounting the worm 3 , the upper part 10 of the transmission housing 1 forms a receiving chamber or worm chamber 12 . The worm 3 is formed in a known manner from a worm shaft 30 and worm teeth 31 , which are formed around the worm shaft 30 in its central region. The end of the worm shaft 30 preferably has a drive shaft b...

Abstract

The invention relates to a gearing mechanism for the adjustment of two reciprocally adjustable parts ( 60, 61 ), especially vehicle parts of a seat adjustment device, a window lifter or a sunroof, wherein the first of the parts ( 60 ) has a nonrotating spindle ( 62 ) or a fixed tooth rack. The gearing mechanism is formed with a wormwheel ( 4, 41 ), which has a spindle nut ( 42 ) non-rotatingly connected thereto in order to drive the spindle ( 62 ) or a worm non-rotatingly connected thereto in order to drive the tooth rack, with a worm ( 3, 31 ) that can be driven so as to transfer a driving force to the wormwheel ( 4, 41 ), and with a gear housing ( 1 ), which houses the worm ( 3 ) and wormwheel ( 4 ) in a supporting manner, and which can be connected immovably with the second of the parts ( 61 ) in its adjusting direction, wherein the gear housing ( 1 ) is formed of a single-piece body with a worm support ( 14 ) and a wormwheel support ( 19 ).

Description

technical field [0001] The invention relates to a gear mechanism for adjusting two mutually adjustable first and second parts, in particular automotive parts of a seat adjustment device, a window regulator or a sliding sunroof of a motor vehicle, Wherein the first part has a screw that cannot rotate relative to the first part or has a rack that is fixed relative to the first part, wherein the transmission mechanism includes: [0002] a worm wheel having a screw nut for driving the screw which is non-rotatable relative to the worm wheel or a worm for driving the rack which is non-rotatable relative to the worm wheel; [0003] a drivable worm for transmitting drive force to the worm wheel; [0004] a transmission housing, which accommodates and supports the worm and the worm wheel, and is non-adjustably connected to the second part in the direction of adjustment, and [0005] The transmission mechanism housing is integrally formed, and is provided with a worm screw support par...
