Abstract: A crash protection device for use in a vehicle has a housing including an opening. An inflatable bag and inflator means are contained within the housing and arranged such that, on activation of the device, the bag inflates and protrudes through the opening. The housing has at least one flap pivotally attached to the remainder of the housing, and flap retainment means for retaining the at least one flap in a position overlying the opening such that (a) before activation of the device, the at least one flap is held in a position in which it retains the bag within the housing and (b) upon activation of the device, the flap retainment means releases said at least one flap to permit protrusion of the bag through the opening. The device has a front cover overlying said housing and mounted on the or one of the flaps.
