PURPOSE: To facilitate a structure, so as to enable after-attachment, by fixing the upper end side to an attaching leg of a head rest, fixing the lower end side to the floor in a housing case of an air bag module, and attaching a collision sensor to the car chamber side surface. CONSTITUTION: In a housing case 6a of an air bag module 6, the upper end side is fixed to an attaching leg 8 of a head rest 3, and the lower end side is fixed to the floor, so that a jumping-out part 13 may face the front part and may be positioned along the side surface of a seat 2. A collision sensor 12 is attached to a car chamber side surface 11. As a result, an air bag module 6 can be after-attached as to be positioned on the side surface of the seat 2 in case of a type in which a head rest 3 is attached on the seat 2 upper surface by an attaching leg 8 with a clearance (d). When the collision sensor 12 is attached to the car chamber side surface, the air bag 7 can be operated in a very short time from the generation of the collision. |
