The invention relates to a gear for adjusting two parts (60, 61) that can be displaced in relation to each other, particularly vehicle parts of a seat adjustment device, of a window lifter or of a sliding roof, wherein the first one of the parts (60) comprises a non-rotatable spindle (62) or a fixed
The invention relates to a gear for adjusting two parts (60, 61) that can be displaced in relation to each other, particularly vehicle parts of a seat adjustment device, of a window lifter or of a sliding roof, wherein the first one of the parts (60) comprises a non-rotatable spindle (62) or a fixed toothed rack. The gear comprises a worm wheel (4, 41), with a spindle nut (42) non-rotatable thereto for driving the spindle (62) or a worm non-rotatable thereto for driving the toothed rack, a drivable worm (3, 31) for transmitting a driving force to the worm wheel (4, 41) and a gear housing (1), which accommodates and supports the worm (3) and the worm wheel (4) and which can be non-rotatably connected to the second one of the parts (61) in the displacement direction thereof, the gear housing (1) being formed by a single-piece body with a worm bearing (14) and a worm wheel bearing (19).

The invention claimed is: 1. A gear for adjusting two parts that can be displaced in relation to each other, particularly vehicle parts of a seat adjustment device, of a window lifter or a sliding roof, the first one of the parts comprising: a non-rotatable spindle and the gear comprising a worm wheel, which has a spindle nut non-rotatable thereto for driving the spindle, a drivable worm for transmitting a driving force to the worm wheel, the worm having first and second opposing sides with each side having a square socket, and with the worm having a driveshaft running axially through the worm, and a single-piece elastic gear housing, which receives and supports the worm and the worm wheel and which can be connected non-displaceably to the second one of the parts in the displacement direction thereof, wherein the gear housing comprises a worm bearing and a worm wheel bearing, the worm bearing is configured in two opposite walls of the gear housing and comprises a worm bearing access opening and the worm wheel bearing is configured in two opposite walls of the gear housing and comprises a worm wheel bearing access opening, the gear housing is formed by a single-piece body with the worm bearing and the worm wheel bearing, first and second opposing drive shaft mounts are provided on the first and second sides of the worm in the axial direction with the first and second drive shaft mounts each configured to receive the drive shaft, and the worm bearing access opening or a section in the transition region between the worm bearing access opening and the worm bearing has a smaller distance (d4) than the diameter (d3) of a worm shaft of the worm and the worm wheel bearing access opening or a section in the transition region between the worm wheel bearing access opening and the worm wheel bearing has a smaller distance (d2) than the diameter (d1) of a worm wheel shaft of the worm wheel, wherein the single-piece elastic gear housing receives both the drivable worm and the worm wheel from beneath the single-piece elastic gear housing. 2. The gear according to claim 1, the worm bearing being configured in one or two opposite walls of the gear housing in the upper section of the gear housing, wherein the worm bearing access opening extends through the corresponding side wall to the bottom of the side wall and/or of the gear housing. 3. A gear according to claim 1, the worm wheel bearing being configured in one or two opposite walls beneath the upper worm, wherein the worm wheel bearing access opening extends through a corresponding side wall to the bottom of the side wall and/or of the gear housing. 4. A gear according to claim 1, wherein the side walls with the worm bearing are configured between the side walls with the worm wheel bearing. 5. A gear according to claim 1, the side walls in the bottom section of the gear housing being formed by mutually spaced legs, wherein the distances of two adjoining legs as worm bearing access openings for the purpose of guiding through a worm shaft and/or as worm wheel bearing access openings for guiding through a worm wheel shaft are dimensioned wide enough and/or elastic enough. 6. A gear according to claim 5, with a housing closure element for closing the bottom of the gear housing, wherein the housing closure element fixes the legs against each other after inserting the housing closure element. 7. A gear according to claim 1, with a housing closure element for closing the bottom of the gear housing, wherein the housing closure element supports the worm wheel and/or the worm in the gear housing from beneath. 8. A gear according to claim 1, wherein at least one inside side wall towards the worm bearing access opening and/or towards the worm wheel bearing access opening has an insertion taper. 9. A gear according to claim 1, wherein at least one drive shaft mount is configured to have the profile of a square socket in the worm. 10. A spindle or worm drive, comprising a gear according to claim 1. 11. A vehicle seat, comprising a gear according to claim 1. 12. A gear for adjusting two parts that can be displaced in relation to each other, particularly vehicle parts of a seat adjustment device, of a window lifter or a sliding roof, the first one of the parts comprising; a non-rotatable spindle and the gear comprising a worm wheel, which has a spindle nut non-rotatable thereto for driving the spindle, a drivable worm for transmitting a driving force to the worm wheel, the worm having first and second opposing sides with each side having a square socket, and with the worm having a driveshaft running axially through the worm, and a single-piece elastic gear housing, which receives and supports the worm and the worm wheel and which can be connected non-displaceably to the second one of the parts in the displacement direction thereof, wherein the gear housing comprises a worm bearing and a worm wheel bearing, the worm bearing is configured in two opposite walls of the gear housing and comprises a worm bearing access opening or the worm wheel bearing is configured in two opposite walls of the gear housing and comprises a worm wheel bearing access opening, the gear housing is formed by a single-piece body with the worm bearing and the worm wheel bearing, first and second opposing drive shaft mounts are provided on the first and second sides of the worm in the axial direction with the first and second drive shaft mounts each configured to receive the drive shaft, and the worm wheel bearing access opening or a section in the transition region between the worm wheel bearing access opening and the worm wheel bearing has a smaller distance (d2) than the diameter (d1) of a worm wheel shaft of the worm wheel wherein the single-piece elastic gear housing receives both the drivable worm and the worm wheel from beneath the single-piece elastic gear housing. 13. A gear for adjusting two parts that can be displaced in relation to each other, particularly vehicle parts of a seat adjustment device, of a window lifter or a sliding roof, the first one of the parts comprising: a non-rotatable spindle and the gear comprising a worm wheel, which has a spindle nut non-rotatable thereto for driving the spindle, a drivable worm for transmitting a driving force to the worm wheel, the worm having first and second opposing sides with each side having a square socket, and with the worm having a driveshaft running axially through the worm, and a single-piece elastic gear housing, which receives and supports the worm and the worm wheel and which can be connected non-displaceably to the second one of the parts in the displacement direction thereof, wherein the gear housing comprises a worm bearing and a worm wheel bearing, the worm bearing is configured in two opposite walls of the gear housing and comprises a worm bearing access opening or the worm wheel bearing is configured in two opposite walls of the gear housing and comprises a worm wheel bearing access opening, the gear housing is formed by a single-piece body with the worm bearing and the worm wheel bearing, first and second opposing drive shaft mounts are provided on the first and second sides of the worm in the axial direction with the first and second drive shaft mounts each configured to receive the drive shaft, and the worm bearing access opening or a section in the transition region between the worm bearing access opening and the worm bearing has a smaller distance (d4) than the diameter (d3) of a worm shaft of the worm wherein the single-piece elastic gear housing receives both the drivable worm and the worm wheel from beneath the single-piece elastic gear housing.
