Air bag apparatus for vehicle
First Claim
1. An air bag apparatus for vehicle, comprising:
- an inflator arranged in a vehicle body to generate air-bag gas at a vehicle collision;
an air bag body connected with the inflator, the air bag body having a plurality of chambers juxtaposed in a fore-and-aft direction of the vehicle, the air bag body being folded and accommodated in a space defined between an interior side face of a roof-side rail forming the vehicle body and a trim for covering the interior side face of the roof-side rail; and
a preventive mechanism for preventing the air bag body from being incompletely inflated at a specified chamber of the chambers, the specified chambers being arranged corresponding to a center pillar forming the vehicle body;
whereby, at the vehicle collision, the air bag body can be completely inflated by the air-bag gas downwardly from the space while springing an lower end of the trim backwardly.

Abstract
An air bag apparatus is capable of inflating an air bag body downwardly and appropriately in spite of the collapse deformation of a center pillar toward a vehicle'"'"'s interior. The air bag apparatus includes a plurality of inflatable chambers juxtaposed in a fore-and-aft direction of the vehicle. In these chambers, the chamber 3A corresponding to the center pillar 13 is provided, on its upper side, with a hooking part 21 for joining an inside cloth 1a of the chamber 3A to its outside cloth 1b. Owing to the provision of the hooking part 21, since the expansion thickness of the chamber 3A is partially restricted, the air bag body 1 being folded in two has its lower end capable of passing under a lower end of a roof trim 16 with ease and without being caught by an upper part of the center pillar 13, accomplishing the expansion of the air bag body 1 in the form of a curtain.
