1. Collision safety device for a vehicle, which comprises:
- a) an air bag inflatable by means of compressed gas;
b) means for inflating said air bag including at least one compressed gas source, andc) outlet valve means communicating the interior of said air bag with the outside atmosphere, said outlet valve means being adapted to be opened and to be closed, said outlet valve means being initially closed and further being adapted to be opened at a predetermined time after said means for inflating said air bag is actuated and if the pressure difference between the interior of said air bag and the outside atmosphere exceeds a predetermined value, said outlet valve means adapted to be closed when said pressure difference between the interior of said air bag and the outside atmosphere no longer exceeds said predetermined value.

Abstract
An air bag collision safety device (air bag) for the occupants of a vehicle has an air bag (3) being inflatable by means of a compressed gas source (1, 2). In order to render possible a soft immersion of the body in the air bag (3), between the air bag interior (51) and the ambiance (52) an outlet valve (53) is arranged which is opened when a predetermined pressure difference between the air bag interior (51) and the ambiance (52) is exceeded (FIG. 1).
