An air bag includes a main body formed by sewing up the respective peripheries of two fabrics, a front panel and a rear panel with a thread, first tether belts and second tether belts for connecting the central portion of the front panel and the central portion of the rear panel. Each of the first tether belts has a low strength portion structured by forming notches on both sides. Stud bolts are inserted into through holes of the first tether belts, through holes of the air bag, bolt holes of the retainer, and bolt holes of a flange. The air bag deploys to the outside of the steering wheel quite rapidly in the initial stage of the deployment, and the front panel extends suitably forward in the latter stage of the deployment.

An inflator is formed of a cylindrical casing filled with propellant, booster filled in a tube, and auto ignition material situated inside the tube. An electrical ingitor is disposed in the casing. First gas outlet holes are disposed on the front surface of the casing and second gas outlet holes are disposed on the rear surface of the casing. The first gas outlet holes are covered by a first film member and the second gas outlet holes are covered by a second film member. As the booster is ignited by the electrical ignitor, a gas pressure of 20.about.25 MPa is applied to break only the first film member. In fire, a gas pressure of 30.about.35 MPa is applied to break both of the first and second film members.

Inflator for air bag device

Passenger's air bag assembly

An air bag device has a retainer, an air bag, a module cover and an inflator. The retainer has a flat plate portion and an erected piece projecting from the plate portion. The cover has a leg faced and fixed to the erected portion. A projection is provided at the leg which is engaged with an opening provided at the erected piece so that the module cover is held at a predetermined position during a process of fixing the leg to the erected piece.

A woven fabric is wove using warps (6) and wefts (7) having coated threads (6a) and (7a), respectively, every other thread, with the remaining threads being uncoated threads (6b), (6c). The coated threads (6a), (7a) are melted by a heat setting treatment, thereby fusing the coated threads (6a) in the warps (6) to the wefts (7) and the coated threads (7a) in the wefts (7) to the warps (6). The woven fabric becomes an uncoated woven fabric on which a thin coating film has not been formed. Accordingly, the uncoated woven fabric has a predetermined amount of air permeability. The threads will not become frayed or tattered and the amount of air permeability will not change even when the uncoated woven fabric is cut.

Uncoated woven fabric and method of manufacturing same

Herein disclosed is an air bag for an air bag system to be mounted on a vehicle for protecting a vehicle passenger. The air bag comprises an air-impermeable cloth disposed at least at the side facing the passenger, and an air-permeable cloth at least at the side of the vehicle body. The air-permeable cloth can be covered from the inside of the air bag with a free member which is made of an air-impermeable or low-permeable cloth.

Air bag

A cover for accommodating an air bag, which is provided at its inner surface with a tear line for starting tear at a start of an operation of the air bag. The tear line is extended up to edges of the cover.

Cover for accommodating an air bag

An automotive air bag system has an air bag and inflators for inflating the bag. The bag and the inflators are held in a holder. A modular cover surrounding the bag engages the holder via clearance such that the cover is held by the holder so as to be movable for a given distance toward and/or away from the passenger.

Air bag system

A mounting arrangement for a vehicle air bag comprises a mounting bracket affixed to a component of the vehicle, a base plate having a mounting portion on which an air bag and an inflator are mounted, and a plurality of fasteners connecting the base plate to the bracket. Plastically deformable structures associated with the fasteners and the base plate are arranged such that the mounting portion of the base plate is displaceable in a direction away from the mounting bracket in response to the forces imposed on the base plate at the end of the development of the air bag.
