AIRBAG APPARATUS

An occupant (P) is restrained to a passenger scat (28) by a seat belt apparatus (30). A passenger-seat side airbag (44) is constructed of a first airbag (40) that is deployed along a windshield (46), and a second airbag (42) that is deployed along an upper surface (12A) of an instrument panel (12). A gap opening is formed between the first and second airbags. That is, since the hip and the chest of the occupant (P) are restrained by the seat belt apparatus (30), the airbag apparatus is intended to specifically restrain the head of the occupant (P), which undergoes a larger inertial movement to a vehicular front side, by the first airbag (40) and the second airbag (42). Therefore, the gas capacity of the passenger-seat side airbag (44) as a whole can be reduced.

AIRBAG AND METHOD OF FORMING AN AIRBAG

A airbag for protecting the driver of a vehicle in the event of a frontal collision is designed for early coupling with the driver whilst initially allowing the driver's head to move forwardly sufficiently to minimize the risk of neck injury. The airbag is made by first providing a flat fabric construction (10) in which first and second superimposed fabric layers are secured together along seams (30, 32, 34, 36) to provide an elongated single bag which is then folded about a fold line (26) intermediate its ends to provide first (20) and second (22) cells, which are connected by triangular gussets (27, 29) on either side. One of the cells (20) is connected with an inflator in the steering wheel hub to be inflated directly from the inflator whilst the other cell (22), nearer the driver, is inflated from the first cell (20) via the restriction afforded by the fold (22), and additionally by seams (35) extending partially along the fold, so that the other cell (22) inflates more slowly and provides ...

SIDE AIRBAG DEVICE FOR VEHICLE

In the side airbag device, in an inflation and deployment state of the side airbag, a tension cloth extendingly disposed across between a front-rear partition and a rear end of the rear bag section is stretched, thereby restricting inflation in the vehicle front-rear direction of the rear bag section. An inflating width in a vehicle width direction of the rear bag section can be increased without significantly changing a position in the vehicle front-rear direction of the front-rear partition. In a flat developed state of the side airbag, the tension cloth is extendingly disposed across between the front-rear partition so folded into two as to protrude toward the rear bag section, and the rear end of the rear bag section. Accordingly, dimensions of each component can be so defined as to cause no redundancy in the rear bag section in the flat developed state, thus compactly folding the side airbag. 1.

AIRBAG DEVICE FOR PASSENGER SEAT

An airbag is configured using a rear surface side when inflation is completed as an occupant protection section. The occupant protection section includes a frontal collision restriction surface, oblique collision restriction surfaces formed both on the left and right sides of the frontal collision restriction surface, and restriction recessed portions installed between the frontal collision restriction surface and each of the oblique collision restriction surfaces. The airbag installs a recessed portion tether that links a tip end side of a recess of each of the restriction recessed portions and a front end side of the airbag to each other to the inside thereof, and when inflation is completed, at the time of substantially dividing the region into two in the left-right direction around the vicinity of the attachment center to the storage part, a remote side region on a side away from a driver seat and a driver seat side region on the driver seat side are provided.
