An air bag apparatus to be mounted in a vehicle in order to protect an on-board passenger by unfolding and inflating a bag body when the bag body is activated. The air bag apparatus is equipped with an inflator, the bag body which is mounted in folded-up condition in such a way that the gas emitted from the inflator can flow into the bag body and equipped with gas vent holes, and a cover body for covering the bag body in the folded-up condition. Each gas vent hole is fitted with a gas-vent quantity regulating valve capable of decreasing the open quantity of the gas-vent hole during the time the bag body is inflating.

Air bag apparatus

An air bag system for a navigator's or passenger's seat includes a casing with an opening arranged in an instrument panel below an inclined windshield. An air bag, having a gas inlet port and accommodated in a folded shape in the casing, is held at the peripheral edge of the gas inlet port by the casing. When inflated, the air bag will extend a great distance toward the passenger's seat and will also interfere with the windshield. The inflator is arranged in the casing for feeding the gases to the gas inlet port of the air bag which is offset from the center of one of the base cloths, and the opening of the casing is covered but opens upon inflation. The air bag is shaped by sewing the peripheral edges of two circular base cloths.

Circular air bag mounted to an instrument panel

A pad of air bag apparatus which, as a molded part, has an enhanced soft touch and which is protected against accelerated time-dependent changes in the physical properties of the pad's core and skin layers, wherein the pad covers the upper surface of an air bag apparatus which is to be mounted on the steering wheel of an automobile or in any other necessary areas. The pad includes of a skin layer formed of a soft first resin material and a core layer formed of a second resin material harder than the first resin material. The first resin material is a styrenic thermoplastic elastomer (TPE) or olefinic TPE having a hardness (JIS A) of 70 and less whereas the second resin material is a polyester based TPE having a flexural modulus of 1,000-4,000 kgf/cm.sup.2 (98-392 MPa) or a polyurethane based TPE having a flexural modulus of 1,000-2,500 kgf/cm.sup.2 (98-245 MPa).

Pad for air bag apparatus

An air bag device having the need of only four securing bolts, one at each corner of the retaining and mounting plates, since in between corners there are two protrusions extending from one of those plates into holding holes in the other.

Air bag device

A pad for covering an inflatable air bag for use in an air bag device includes an insert member of a generally box-shape made of a synthetic resin. The insert member has an upper wall openable upon inflation of the air bag and four side walls extending downwardly from an peripheral edge of the upper wall. A reinforcing metallic member is embedded in at least the front and rear side walls of the insert member. A covering member made of a soft synthetic resin covers the insert member.

Pad for air bag device

A cover for an inflatable air bag is provided which has an upper portion adapted to break upon inflation of the air bag and a side portion which extends downwardly from the peripheral edge of the upper portion. An insert is embedded in the cover and includes a flexible net and a flexiblle reinforcing band assembly. The net includes a side portion embedded in the side portion of the cover and upper portions which are embedded in upper portions of the cover. Coupling portions vertically couple the side portion of the net to the upper portions thereof. The reinforcing band assembly includes a horizontal band which is coupled by for example sewing to the side portion of the net along the entire perimeter of the side portion of the net and vertical bands which are sewn to the horizontal band and to the side edges of the upper portion and/or the coupling portions of the net. The vertical bands of the reinforcing band assembly are bent back at their lower ends so that the lower portions surround the horizontal band are are connected thereto. Since the vertical bands are wrapped around and sewn to the horizontal band, forces which act on the vertical bands when the air bag is inflated are distributed to the horizontal band so that the strength of the cover is great enough to withstand tensile forces which act on the coupling portions of the net.

Cover for air bag unit

A pad covering an inflatable air bag for use in an air bag device provided with an upper wall which is broken by inflation of the air bag, and side walls which extend downward from the peripheral edges of the upper wall. A base insert made of metal is disposed next to the side walls, and a flexible net insert is connected to the inner surface side of the upper side of the base insert through the attaching plate. The base insert, the net insert and the attaching plate are covered by the coating layer made of soft synthetic resin. The net insert is connected to the attaching plate by means of sewing, and the attaching plate is fixed to the base insert preferably by rivets.

There is disclosed a pad for use in an air bag device enclosing an air bag which inflates in case of an accident. The device is mounted to mount members disposed around the bag. The pad is shaped like a box, and comprises an upper wall and side walls extending downward from the fringes of the upper wall. The pad is molded integrally with an insert on which a coat layer is formed out of a soft synthetic resin. The coat layer has a thin-walled portion that breaks when the air bag inflates. The thin-walled portion is disposed at a given position on the upper wall. The insert comprises a rectangular tubular base portion made from a synthetic resin and a plurality of flexible nets disposed on opposite sides of the thin-walled portion. The base portion is disposed inside the side walls. The nets are disposed on the upper wall and connected to the top of the base portion. An attachment portion for mounting the pad to the mount members and setting portions for setting the pad in a mold used to mold the coat layer are formed on the base portions.
