Abstract: Connecting pins are provided at connecting portions on the airbag device side in such a manner as to project therefrom, whereas connecting parts adapted to rotate in directions normal to an axial direction of the connecting pins are disposed on the main body side. The hook portions of the connecting parts interfere with a guide surfaces of the connecting pins which are forced in along the axial direction thereof to thereby be disposed at waiting positions where the hook portions can rotate in the lock releasing direction.

Abstract: A pad or cover for an air bag assembly formed of a thermoplastic elastomer and having an outer wall that includes a substantially H-shaped thin-walled breaking seam designed to break when the air bag is actuated. The breaking seam is H-shaped, as viewed in a vertical direction, and the cover includes an ordinary portion outside of the breaking seam. A horizontal seam portion of the substantially H-shaped portion has straight line portions respectively connected to two vertical seam portions lying on both left and right sides of the substantially H-shaped configuration and a curved U-shaped portion that is interposed between the straight line portions. The thickness of the ordinary portion at the outer peripheral side of the U-shaped portion is thicker than the thickness of the ordinary portions in the vicinities of intersections between the vertical seam portions and the straight line portions.

Abstract: An air bag apparatus includes a pad provided with a mounting piece portion extending downwardly from a bottom surface of the pad and having mounting holes. The mounting piece portion is fixed to a side wall of a bag holder in a state in which the mounting piece portion is held between a backplate and the side wall of the bag holder by rivets inserted into the mounting holes of the mounting piece portion and into mounting holes of the side wall of the bag holder and mounting holes of the backplate. Engagement portions for regulating an upward movement of the mounting piece portion are formed at a lower end portion of the mounting piece portion and the backplate except at those portions below the mounting holes. The engagement portions are formed to be recesses and projections which are adapted to engage are another.

Abstract: 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).

Abstract: A pad for an air bag apparatus is provided which assures that a part of the pad between a breakage portion and a side wall portion is not scattered away in pieces when the air bag expands. The pad includes an upper wall portion and side wall portions extending downward from the periphery of the upper wall portion. Cover portions adapted to be opened upon breakage of a breakage portion at the time of expansion of the air bag are formed over the upper wall portion. A predetermined number of vertically extending triangular plate-shaped ribs are integrally molded with the upper wall portion and the side wall portions along the periphery of the breakage portion and extend from the side wall portions to the breakage portion.
