Abstract
An air bag apparatus for a vehicle is characterized in that an air bag, an inflator and acceleration sensors for controlling the inflator are closely disposed in a single place to constitute an air bag unit. The acceleration sensors in the air bag unit are made up of a plurality of acceleration sensors of different kinds. The air bag unit is disposed on a steering wheel and each of the acceleration sensors is disposed such that the direction of movement of a movable element to be provided in each of the acceleration sensors is parallel to an axis of rotation of the steering wheel. The inflator is electrically ignited and each of the acceleration sensors controls the electric current supply to the inflator.
