Abstract
A seat frame is disclosed for a height-adjustable and tiltable seat pan of a motor vehicle seat. The seat frame has two side rails, a first cross bar, a second cross bar, and a drive unit. The first cross bar is supported in the two side rails and the second cross bar serves to support the seat pan. The second cross bar is mounted so as to be rotatable about fixed first axis in the two side rails. The second cross bar is rotated by the drive unit. The drive unit has an actuating motor and an actuator that is displaceable via the actuating motor and connected to the second cross bar outside the first axis. The drive unit is mounted on the first cross bar and rotatable about a second axis of the first cross bar which is fixed in the two side rails.
