Abstract

Drive of a seat adjusting device, especially for motor vehicles, with a spindle that is fastened on a first of two rails, which are adjustable with respect to each other, by means of at least one mounting located at the end of the spindle and with a transmission driven by a motor that is mounted on the second rail, whereby the mounting has one part as a base plate, from which two walls at a distance from each other extend upward and that at least one end of the spindle is fastened between these two walls.

First claim

I claim:

1. A drive of a seat adjusting device, especially for motor vehicles, comprising a spindle that is fastened on a first of two rails, which are adjustable with respect to each other, by means of a two-part mounting, comprising a base plate and a U-strap, located at the end of the spindle and with a transmission driven by a motor that is mounted on the second rail, further comprising wherein two walls at a distance from each other extend upward from the base plate and that at least one end of the spindle is fastened between these two walls, wherein the two walls are two longitudinal legs of the U-strap, the base plate has two slots at a distance from each other that run at least approximately parallel to a spindle axis of the spindle and the two longitudinal legs of the U-strap are slid from below the base plate through the slots such that a transverse leg of the U-strap is in contact with the underside of the base plate wherein the base plate has a recess on its underside, in which the transverse leg of the U-strap engages so the mounting has an at least approximately flat underside and wherein the upper side of the base plate comprises a formed elevation that is opposite the recess on the underside of the base plate, such elevation and recess each extending across the width of the base plate.

2. The drive of claim 1 , further comprising wherein the walls have at least approximately half the length of the base plate.

3. The drive of claim 1 , further comprising wherein the base plate and the U-strap are tightly connected to each other by one of the processes taken from the group consisting of welding, bonding, toxing and clinching.

4. The drive of claim 1 , further comprising wherein the base plate and the transverse leg consist of metal taken from the group consisting of steel, sheet steel and metal casting.

5. The drive of claim 1 , further comprising wherein the base plate has at least one hole, and such holes, if a plurality, are arranged next to each other and are collinear with the axial direction of the spindle.

6. The drive of claims 1 , further comprising wherein the base plate has a rectangular outer contour.

7. A drive of a seat adjusting device, especially for motor vehicles, comprising a spindle that is fastened on a first of two rails, which are adjustable with respect to each other, by means of a two-part mounting, comprising a base plate and a U-strap, located at the end of the spindle and with a transmission driven by a motor that is mounted on the second rail, further comprising wherein two walls at a distance from each other extend upward from the base plate and that at least one end of the spindle is fastened between these two walls, wherein the two walls are two longitudinal legs of the U-strap, the base plate has a rectangular outer contour and two slots at a distance from each other that run at least approximately parallel to a spindle axis of the spindle and the two longitudinal legs of the U-strap are slid from below the base plate through the slots such that a transverse leg of the U-strap is in contact with the underside of the base plate and such that the two longitudinal legs are each located at a set distance within the edges of the rectangular outer contour of the base plate, wherein the base plate has a recess on its underside, in which the transverse leg of the U-strap engages so the mounting has an at least approximately flat underside and the base plate, such elevation and recess each extending across the width of the base plate.

8. The drive of claim 7 , further comprising wherein the walls have at least approximately half the length of the base plate.

9. The drive of claim 7 , further comprising wherein the base plate and the U-strap are tightly connected to each other by one of the processes taken from the group consisting of welding, bonding, toxing and clinching.

10. The drive of claim 7 , further comprising wherein the base plate and the transverse leg consist of metal taken from the group consisting of steel, sheet steel and metal casting.

11. The drive of claim 7 , further comprising wherein the base plate has at least one hole, and such holes, if a plurality, are arranged next to each other and are collinear with the axial direction of the spindle.

12. The drive of claim 7 , further comprising wherein the base plate has a rectangular outer contour.
