Abstract

An inflatable impact cushion for passengers of a motor vehicle, which in case of an accident is adapted to be selectively filled with the available gas by the increasing pressure by means of several sequentially triggerable ignition stages depending on the strength of the deceleration; in the starting condition, a portion of the protective cushion is separated off by a seam or the like, while the seam or the like is destroyed by the increasing pressure in such a manner that in the end condition the entire volume of the protective cushion is available.
