A protective device for motor vehicle airbag systems to protect the vehicle occupants utilizes a vessel whose wall piece, which can break out, is configured as part of the wall of a hollow valve block provided with the outflow orifice. The wall piece is equipped with an extension projecting into the interior of a valve block. The piston rod is guided displaceably, transversely relative to the extension in the valve block, and moved by a pyrotechnic propellent charge. The rod serves to break out the wall part and is provided with a collar which, in the event of ignition, strikes against the extension and thus leads not to a violent breaking-out, but to a pivoting of the wall piece before the final breaking-out.

Motor vehicle occupant protective device

A pressure vessel for storing a gas for use in airbag protection systems in passenger transport has an outflow valve connected to the housing of the pressure vessel at a predetermined breaking zone and contains a piston which extends to a pyrotechnic system arranged in the vessel interior. Influencing the outflow characteristic of the gas flowing out of a pressure vessel into an airbag in a controlled manner during the opening movement of the outflow valve is attained because the outflow valve contains a control body which adjoins the predetermined breaking zone and extends in the direction of the pyrotechnic system and the cross-section of which changes in the axial direction of the outflow valve.

Pressure vessel for the storage of a gas having an outflow valve

A pressure vessel for storing a highly pressurized pressure medium for use with motor vehicle air bags and the like has an elongated, pressure-tightly closable hollow body as well as at least one opening for the flowing-out of the pressure medium. The vessel can be made small and light by surrounding the circumference of the hollow body with a fiber composite winding.
