Abstract: A vehicular rear impact sensor mounting structure includes a pair of rear side members which are parallel to one another in a vehicle width direction; a rear bumper reinforcement that is connected to rear end portions of the rear side members; a lower back panel that is fitted to the rear side members at a predetermined distance from the rear bumper reinforcement, and that is forward of the rear bumper reinforcement in a vehicle longitudinal direction. A rear impact sensor for detecting a rear, impact to a vehicle is provided on the inside surface of the lower back panel.

Abstract: An occupant protection apparatus includes an airbag provided at a seat portion of a vehicle seat. The airbag is inflatable in such manner as to push up at least a part of a cushion body of the seat portion. At the time of collision of the vehicle, an ECU permits inflation of the airbag if a sensor senses that an occupant is seated on the seat, and inhibits inflation of the airbag if the sensor senses that no occupant is seated on the seat. Therefore, when no occupant is seated on the seat, inflation of the airbag is inhibited at a vehicle collision.

Abstract: An air bag deployment apparatus for a seat back includes a support bracket and deployment strap. The support bracket has a reaction surface which extends behind the air bag inflator. The deployment strap is sewn to the inside of a seam line, a trim cover, and extends from the front of the seat along the side to an aperture formed in a foam cushion. The strap passes through the cushion to the reaction surface of the support bracket. The support bracket may be formed with panels which parallel the alignment of the strap. The strap is supported without slack to reduce the gas force necessary for stable deployment of the air bag.
