Abstract

In an impact protection cushion which can be accommodated in the steering wheel region for protection of the vehicle driver, a tearing seam is provided which joins the cushion upper part, which moves forward upon inflation, to the cushion lower part fastened to a fixed vehicle part. This arrangement prevents any radiating forward movement of parts of the cushion upper part, in particular, of a central region laying opposite the gas inflow opening in the cushion lower part without restraining straps.
