Abstract

An impact protection system for an occupant of a motor vehicle with a prefabricated constructional unit that is fastened at parts of the vehicle body and which includes a generator housing, a base plate, a gas cushion, a generator and a cover provided with a tearing seam, is provided with a receiving frame that is adjustably connected with a support part of a dashboard. The prefabricated constructional unit is fastened at the receiving frame. The support partg delimits a recess of the dashboard that is closed off by a recess cover. The cover, via a releasable snap-in connection and an additional fastening, interacts with the receiving frame such that when the gas cushion unfolds, the snap-in connection opens up and the cover, via a desired bending point formed by the receiving frame, is swivelled preferably upward in the direction of a windshield.
