Abstract
Abstract An air bag apparatus for a vehicle according to the present invention includes a bracket secured to an arbitrary position of the vehicle and an air bag module attached to the bracket. The air bag module has a base attached to the bracket, an inflator for generating gas, an air bag body which is unfolded with gas generated by the inflator and a guide for restricting a direction in which the air bag body is unfolded. The base and the guide are individual elements arranged to be assembled to create a space. The base and the guide are arranged to be assembled so as to be disposed in the space created by the base and the guide. Therefore, the guide can be disposed in a limited space in the air bag module without obstructing the other units. Moreover, the guide is able to appropriately guide the direction in which the air bag body is unfolded.
