Abstract: A gas cushion on the passenger side for motor vehicles, especially for passenger motor vehicles, includes two mutually oppositely disposed approximately trapezoidally shaped surface or boundary areas. The unique shape of the cushion provides a particularly safe protection effect in the critical upper impact area without increase of the overall volume of the gas cushion. One of the trapezoidally shaped boundary areas serves as impact surface facing the passenger while the other trapezoidally shaped boundary area includes at least one opening serving the gas admission. The gas cushion is so arranged in the motor vehicle that the trapezoidally shaped boundary areas taper from top to bottom.
