Patent abstract
An air bag apparatus includes: a supporting plate; an air bag case mounted on the supporting plate such that a space is formed therein; an air bag cushion installed in the space and attached to the supporting plate; an inflator for supplying a gas to the air bag cushion, the inflator being mounted at the supporting plate; and a clamping device for clamping a middle portion of the air bag cushion, the clamping device being coupled with the supporting plate. The inflator may supply the gas to side portions of the air bag, such that the side portions expand for a predetermined time while the middle portion is clamped by the clamping device, and when the inflating force of the air bag overcomes the clamping force, the middle portion expands.
