Seat base frame for a motor vehicle seat
First Claim
1. A seat base frame for a motor vehicle seat comprising:
- a parallel pair of tracks extending in a longitudinal direction and spaced apart from each other in a latitudinal direction,wherein each track has an upper rail and a lower rail,wherein the upper rails are movable in the longitudinal direction relative to the lower rails;
locking devices, each of the lower rails having one of the locking devices mounted thereon and configured to lock the upper rail relative to the lower rail in a locked position to prevent movement of the upper rail in the longitudinal direction, and configured to release the upper rail relative to the lower rail in a release position to allow movement of the upper rail relative to the lower rail in the longitudinal direction,wherein the upper rails are configured to connect to a seat structure;
mounting linkage holders, each of the upper rails having one of the mounting linkage holders attached thereto;
a transverse support extending in an axial direction that is substantially perpendicular to the upper rails,wherein each end of the transverse support is attached to a respective one of the mounting linkage holders,wherein the transverse support fixes the parallel pair of tracks together in the axial direction such that collapse of the seat base frame in the event of a car crash is prevented by the transverse support,wherein the transverse support is rotatable about the axial direction relative to the upper rails and the mounting linkage holders,wherein the transverse support is fixed in the longitudinal direction relative to the mounting linkage holders;
an actuating lever attached to the transverse support;
a control lever attached to the transverse support and spaced apart from the actuating lever in the latitudinal direction,wherein the actuating lever and the control lever are attached to the transverse support such that the actuating lever and the control lever are rotatably fixed relative to one another,wherein the actuating lever and the control lever are each engageable with a respective one of the locking devices to move the locking devices between the locked position and the release position; and
mounting linkages, each of the mounting linkage holders having one of the mounting linkages pivotably attached thereto,wherein the mounting linkages are at least one of a front mounting linkage and a rear mounting linkage.

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.
