The invention is an improvement in inflatable air cushion systems for use as devices to protect passengers in vehicles. Pressure is transferred from an elongated gas container through a nozzle to an inflatable bag or envelope for inflating it. Openings are formed for transferring gas from the container through the nozzle by means of an explosive charge. The improvements of the herein invention reside in that the gas container and transfer means or nozzle are fabricated as separate parts. Spaced openings are provided in the nozzle along its length with solid portions or ribs between the openings. These openings are in the nozzle rather than in part of the elongated tank. The elongated tank and the nozzle are formed as extrusions. These parts are joined together by way of tongue and groove joints that form a strong joint preventing failure of the tank resulting from pressure.
