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 mec
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).

The invention claimed is: 1. A gearing mechanism for adjusting two reciprocally adjustable parts adjustable relative to one another, suitable for use with vehicle parts including a seat adjustment device, a window lifter or a sunroof, the gearing mechanism comprising: a nonrotating spindle fixable
The invention claimed is: 1. A gearing mechanism for adjusting two reciprocally adjustable parts adjustable relative to one another, suitable for use with vehicle parts including a seat adjustment device, a window lifter or a sunroof, the gearing mechanism comprising: a nonrotating spindle fixable to a first of the two reciprocally adjustable parts; a wormwheel, which has a spindle nut non-rotatingly connected thereto in order to drive the spindle and which has a wormwheel shaft; a worm positioned to transfer a driving force to the wormwheel and which has a worm shaft; a gear housing formed as a single-piece gear body; a gear housing closure; the gear housing receiving the worm and the wormwheel by insertion of the worm and wormwheel in a common direction into the gear housing, and the gear housing holding the worm and the wormwheel in a supporting manner, with the gear housing fixable to the second of the two reciprocally adjustable parts; the gear housing having two first facing walls, each of the two first facing walls having a worm support for receiving the worm shaft; the gear housing having two second facing walls, each having a wormwheel support for receiving the wormwheel shaft; the gear housing configured to receive the worm and wormwheel rotatably positioned about their respective longitudinal axes with the worm securely mounted in the gear housing and supported by the wormwheel, wherein each worm support has a worm support access opening with a distance between walls of the worm support access opening being less than a diameter of the worm shaft, and wherein each wormwheel support has a wormwheel support access opening with a distance between walls of the wormwheel support access opening being less than a diameter of the wormwheel shaft, and wherein the gear housing closure comprises support surfaces for supporting the wormwheel shaft. 2. A gearing mechanism according to claim 1, wherein each worm support access opening opens in a mounting direction of the worm. 3. A gearing mechanism according to claim 1, wherein the each wormwheel support extends through the respective second facing wall. 4. A gearing mechanism according to claim 1, in which the two first facing walls with the worm supports are formed between the two second facing walls with the wormwheel supports. 5. A gearing mechanism according to claim 1, wherein the two first facing walls and the two second facing walls further comprise legs, with spacing between the legs on the two second facing walls forming the wormwheel support access opening. 6. A gearing mechanism according to claim 5, wherein the gear housing closure is affixed to the legs to close the gear housing. 7. A gearing mechanism according to claim 1, wherein the worm support access opening further comprises at least one retaining ridge.
