ABSTRACT:
An airbag restraint system for an automotive vehicle includes an airbag made up of front and rear sheets which are generally circular and sewn together at their peripheral portions. When retracted in a central part of a steering wheel, the airbag is folded in a deflated condition along two lines which are parallel and separate from each other and located such that a central opening for an inflator is positioned therebetween. A region of the rear sheet between the two bending lines is coated with a coating material to prevent gas flow therethrough. When retracted in the steering wheel, the airbag has a space which is formed between the coated section of the rear sheet and the front sheet, which is coated at its whole surface with the coating material, so that the space is confined by the coated sections of the front and rear sheets. When gas is ejected from an inflator into the space, the airbag can be effectively developed to ensure inflation of the airbag.
