Abstract

A seat base frame has pairs of tracks, each having an upper rail longitudinally displaceably guided relative to a lower rail and lockable by means of a locking device on the lower rail. A seat structure is connected to the upper rails, and a transverse support extends substantially perpendicular to the upper rails and is connected thereto. The transverse support is fixed in the axial direction thereof relative to the upper rails and rotatably connected thereto, wherein an actuating lever and a control lever are disposed rotationally fixed relative to each other and spaced apart from each other on the transverse support such that each can be engaged by a locking device for adjusting the locking device between a locked position fixing the upper rail relative to the lower rail and a release position releasing the upper rail relative to the lower rail.

Claims

1. A seat base frame for a motor vehicle seat, with

pairs of tracks disposed in parallel spaced apart from each other

each having an upper rail longitudinally displaceably guided relative to a lower rail and lockable by means of a locking device on the lower rail,

a seat structure connected to the upper rails and

a transverse support extending substantially perpendicular to the upper rails and connected thereto,

wherein

the transverse support fixes the pairs of tracks in a crash-stable manner against each other supportingly in its axial direction with respect to upper rails and is rotatably connected with it, wherein, for the adjustment of the locking device, an actuating lever and a control lever are arranged in a twist-proof manner at a distance from each other and each engageable with a locking device between a locked position fixing the upper rail on the lower rail and a release position releasing the upper rail with respect to the lower rail on the transverse support.

2. The seat base frame according to claim 1, wherein at least one of a front and a rear mounting linkage is arranged in a jointed manner on the upper rail.

3. The seat base frame according to claim 1, wherein at least one of the front and the rear mounting linkage is respectively connected in a jointed manner with a mounting linkage holder arranged on the upper rail.

4. The seat base frame according to claim 1, wherein the transverse support is rotatably connected and fixed in the axial direction on the end side with two oppositely arranged mounting linkage holders.

5. The seat base frame according to claim 2, wherein the mounting linkages of the door-side and vehicle-center pair of tracks have a differing geometry.

6. The seat base frame according to claim 5, wherein the mounting linkage of at least one seat rail, has a door-side or vehicle-center-aligned bend.

7. The seat base frame for a motor vehicle seat according to claim 2, wherein at least one front mounting linkage is engageable with the transverse support.

8. The seat base frame according to claim 7, wherein the front mounting linkage engageable with the transverse support has a contact surface adjusted to the contour of the transverse support.

9. The seat base frame according to claim 1, wherein the transverse support is formed by a cross tube.

10. The seat base frame according to claim 9, wherein the cross tube rests on the upper rails via end-side front surfaces.

11. The seat base frame according to claim 1, wherein the actuating lever and the control lever, respectively engageable with a locking device, are welded.
