<p>PROBLEM TO BE SOLVED: To apply a knee cushion which is soft for a knee by deforming a cover in the direction of an occupant's knee by a gas bag when an automobile collides. SOLUTION: At the time of collision, pyrotechnics material stored in a gas generator 9 is ignited to discharge an amount of gas which is stored and gas passes through several discharge ports 19 of a housing of the gas generator and flows out into a gas bag 5 to inflate the gas bag. Upon completion of inflation, the gas bag 5 is applied to an inner side of a gas bag cover 13 so that the gas bag cover 13 is deformed in the direction of an occupant's knee lastly. The gas bag cover 13 is not ruptured and removed by a hinge, comes into contact with the gas bag 5, and forms a knee cushion together with the gas bag 5. The knee of the occupant in a vehicle collides against this knee cushion to prevent plunging into of the occupant into a zone around the knee. Since the travel of the knee into the zone around the knee which occurs at the time of collision is suppressed early, the knee collides against a knee binding device at comparatively low speed.</p> |
