摘要

The fastener has a seat cross beam (1) with a component (2) that is fastened at a motor vehicle body base (5), and a component (3) that is arranged over the component (2). The components form two chambers (10, 12), which are arranged one above the other. The chambers are separated from each other by a cover (9) of the component (2). The yield strength of the component (3) is twice as large as the yield strength of the component (2). The component (3) is provided with a clamping hole (13) for fastening a seat rail.
