Patent ID: 8876158

Claim:
An air bag apparatus, comprising: a base plate; gas generators including a first gas generator and a second gas generator, fixed to a first side of the base plate; a cover member covering the gas generators, the cover member facing the first side of the base plate; and an air bag accommodated in contact with the base plate; the base plate having a hollow formed in the first side of the base plate and provided with a communication hole, the gas generators being arranged in the hollow and opposing end surfaces of adjacent gas generators defining a space therebetween, and a first gap, for communicating with the communication hole, is formed between the hollow and a gas discharge port of the respective gas generators, the cover member covering the adjacent gas generators and defining a second gap, in communication with the first gap, between the cover member and the gas discharge port of the respective gas generators, the air bag being accommodated such that a gas inlet thereof encloses the communication hole in the hollow from a second side, opposite to the first side, of the base plate, the air bag, the base plate and the cover member being integrally fixed by fastening, with a fastening member, the base plate, the cover member and a frame shaped air bag attachment member which is arranged to abut against the gas inlet in an inside of the airbag, the adjacent gas generators being fixed by the hollow of the base plate and the cover member, and a sealed gas discharge path being formed by the first and second gaps defined by the cover member and the base plate, and leading gas from each gas discharge port of the adjacent gas generators to the gas inlet of the air bag.
