摘要： A gas bag module for use in vehicles has a housing and an inflator arranged on the bottom of the housing. A normally folded gas bag is accommodated within the housing. A diffusor is arranged between the inflator and the folded gas bag. The diffusor consists of a first diffusor part fixed to the bottom of the housing and a second diffusor part movably mounted on the first diffusor part. The second diffusor part is movable with respect to the first diffusor part from a normal retracted position closer to the bottom of the housing to an advanced position further away from the bottom of the housing under the action of gas pressure generated by the inflator.
