Adjustable device for motor vehicle seat
View Patent ↗Disclosed is an adjustment device for a motor vehicle seat having an adjusting element adjustably disposed in its longitudinal direction and in the area of one end, connectable in an articulated manner to a vehicle seat structure, and a drive unit driving the adjusting element. In order to provide an adjustment device of the initially named type, that can be disposed at a vehicle seat component in a simple and reliable manner, it is provided that the drive unit comprises means for the articulated, particularly pivotal, connection to a vehicle seat component, particularly a side member of a seat base frame.
1. An adjustment device for a motor vehicle seat, having
an adjusting element adjustably disposed in its longitudinal direction and in the area of one end, connectable in an articulated manner to a vehicle seat structure, and
a drive unit driving the adjusting element, comprising a detachably connected retaining element for pivotal connection of the drive unit to a vehicle seat component,
wherein the retaining element comprises a through opening for receiving the adjusting element in a displaceable manner.
2. The adjustment device according to claim 1 , wherein the retaining element comprises a bore, in particular a threaded bore for receiving a bearing bolt that can be disposed so as to rotate at a vehicle seat component.
3. The adjustment device according to claim 2 , wherein the bore and the adjusting element are disposed so that their longitudinal axes run essentially at right angles to each other and in a common plane.
4. The adjustment device according to claim 1 , wherein the retaining element comprises a stop body that can be brought into contact with the vehicle seat component.
5. The adjustment device according to claim 4 , wherein the stop body is disposed coaxially to the bore.
6. The adjustment device according to claim 4 , wherein the stop body is formed integrally with the retaining element.
7. The adjustment device according to claim 4 , wherein the stop body comprises a slide coating.
8. The adjustment device according to claim 1 , wherein the retaining element is constructed such that it encompasses the drive unit at least partially in a U-shape.
9. The adjustment device according to claim 1 , wherein the drive unit comprises a motor unit and a transmission unit, wherein the adjusting element is in engagement with the transmission unit.
10. The adjustment device according to claim 9 , wherein the motor unit is coupled via a worm disposed on an output shaft to a worm gear mounted so as to rotate in a transmission housing, wherein the worm gear is constructed as a spindle nut for driving a spindle disposed axially in the worm gear.
11. The adjustment device according to claim 10 , wherein the spindle comprises a connecting link at the first end for the articulated connection to a lever, and a stop element at its second end opposite to the first end.
12. A motor vehicle seat having a seat base frame and an assembly adjustable with respect to the seat base frame, wherein the adjustment device according to claim 1 is disposed in a pivotal manner at the seat base frame.
13. The motor vehicle seat according to claim 12 , wherein the adjustment device is mounted in an articulated manner via a bearing bushing disposed in an opening of the vehicle seat component.
14. The motor vehicle seat according to claim 13 , wherein the vehicle seat component is a side member.
