PURPOSE: To reduce the cost of manufacture by cutting intake flaps into housing walls as part of a receiving housing and enabling them to pivot about a lateral edge existing in the receiving housing in the direction of the housing interior. CONSTITUTION: Intake flaps 10 can be opened by the underpressure generated in the unfolding of a gasbag casing 6 by virtue of which an escape of internal gases from a receiving housing 2 through apertures 7 is prevented. Each intake flap 10 is cut into the housing wall 8 as part of the receiving housing 2 and is hinged pivotably about a lateral edge 11 existing on the receiving housing 2 in the direction of the housing interior 12. Its pivot is formed of linear thin parts 14 and 14' or a linear thick part 15 positioned near them. Such a pivot can be especially easily realized at the time of manufacture of a receiving housing 2 when it is made of synthetic resin. |
