Abstract
An air bag device for use with a motor vehicle has an inflatable bag on the inner surface of which is provided a thin film-like layer of gas generating agent. At least one igniter is mounted in a part of the thin gas generating agent layer. When the vehicle encounters a collision, the gas generating agent is ignited by the igniter to generate gas. The gas fills up and thereby inflates the bag to restrain an occupant of the vehicle.
Claims7
An air bag device for protecting a vehicle occupant, comprising:
- a gas generating agent for generating gas when burned;
- an igniter for igniting said gas generating agent;
- an inflatable bag to be inflated by the gas generated by said gas generating agent, said inflatable bag including a base cloth and a heat-resistive coating provided on an inner surface of said base cloth;
- and
- a substantially imperforate protector cover provided inside of said inflatable bag;
- said gas generating agent being provided in the form of a thin layer of a gelatinous material on an inner surface of said heat resistive coating;
- said protector cover being disposed on an inner surface of said thin layer of said gas generating agent for isolating parts of said thin layer which face each other when said bag is folded up and for preventing said thin layer from coming off;
- said igniter being provided in a part of said thin layer of said gas generating agent wherein said protective cover is melted and/or torn down when gas is generated by said gas generating agent.
