摘要

The invention relates to a seat underframe for motor vehicle seats, with two pairs of rails arranged at a distance from each other and each having a seat rail (2) and a floor rail (3), a seat carrier (7), in each case two pivoting arms (4, 5) which are connected at one end in an articulated manner to the seat carrier (7) and at the other end in an articulated manner to the seat rails (2) and fix the maximum distance between the seat carrier (7) and the seat rails (2), and a drive unit (6) adjusting the seat carrier (7) between a lower starting position and an end position. In order to provide a seat underframe for motor vehicle seats, in particular for passenger seats, which enables the motor vehicle seat to be transferred into a position in which the seating comfort, which arises owing to the leg room, can be increased in a complementary manner behind the motor vehicle seat, the drive unit (6) for adjusting the seat carrier (7) is formed beyond a height end position which is fixed during normal operation.
