Abstract: An airbag module removal structure includes a pair of brackets which extends from an instrument panel and is disposed with a space to sandwich an airbag module, a first hook member secured to one side of the airbag module and a second hook member secured to the other side of the airbag module, and each of the first and second hook members includes an engagement part capable of being inserted into a hole provided in each of the brackets, and a clearance between the brackets and sizes of the engagement parts of the first and second hook members are set such that the first hook member is removed from the hole corresponding to the first hook member, and then the second hook member is removed from the hole corresponding to the second hook member.

Abstract: A cover structure for an air bag device comprises a cover including a first member having a plane-like portion and a second member having a vertical portion connected through a curved part with the plane-like portion at an angle, and a rupturable groove formed on a surface of the cover opposite to an air bag in the air bag device to rupture in response to inflation of the air bag and to form an opening for causing the air bag to expose. The rupturable groove is formed throughout the first and second members in such a manner that it extends to coincide substantially with a direction of shearing force applied on the cover when the rupturable groove is ruptured.

Abstract: An airbag apparatus comprises an airbag lid (5) which is provided by a fragile line (3) on a resin instrument panel (2) and a door for holding (8) disposed in the back surface of the airbag lid (5) by fixing a boss (15) projected from the back surface of the airbag lid (5), and the holding door (8) includes an door body portion (9), an installation portion (10), and a hinge portion (11). In the airbag apparatus, a longitudinal bead (21) extending from the hinge portion (11) side to the leading end side of the door body portion (9) is provided, and lateral beads (22, 23) positioned between the hinge portion (11) and an installation portion (hole 16) to the boss disposed in the vicinity of the hinge portion (11) are provided; furthermore, the damage between the holding door and the airbag lid at the time of expanding the airbag can be prevented by constructing the longitudinal bead (21) and the lateral beads (22, 23) to be crossed.

Abstract: An air bag unit includes a restrictive element, affixed within the air bag unit, which restricts lateral expansion of the air bag unit. The lateral restriction increases longitudinal expansion toward an occupant position.

Abstract: A retainer case (4) has a lower portion (4a) defining a gas diffusion chamber (5), and an upper portion (4c) cooperating with an intermediate portion (4b) to define an accommodation chamber (6), a diffuser member (15) separates the gas diffusion chamber (5) from the air bag accommodation chamber (6), with gas communication allowed therebetween through a gas inlet (16) of the diffuser member (15), an infaltor (11) is disposed in the gas diffusion chamber (5), an airbag (8) is accommodated in the accommodation chamber (6), having a retained part (8b) in a space (S1) between the intermediate portion (4b) and the diffuser member (15), and an inward projection (18) of the intermediate portion (4b) and an inward projection (17) of the diffuser member (15) constitute a gas invasion restricting structure (17+18) for restricting a gas invasion from the gas diffusion chamber (5) into the space (S1).

Abstract: A front and a back cloth body are bonded at the edges to form a bag. The bag is inflated from an air bag device disposed on a seat back so that it expands between a seat and a side door, thus protecting a passenger over a range from a torso to a head. The bag contains a supply section which holds an inflator that injects a pressurized fluid into the bag. A torso protection section, contiguous with the supply section, extends forward from the supply section. A head protection section, contiguous with the torso protection section, extends upward from the torso protection section. When the inflator is activated pressurized fluid is injected to expand head protection section. The resulting inflation pressure tends to make front side air bag pivot around the supply portion. To prevent this, in one embodiment an auxiliary section is inflated with a pressure in a direction opposite to the rotation at roughly the same time as the expansion of the head protection section.

Abstract: An airbag for an airbag device includes a primary cloth and a secondary cloth constrainingly attached by way of least one tether strip. Primary cloth, secondary cloth, and reinforcement cloth are layered together. The edges of the primary cut cloth and the secondary cut cloth, and the reinforcement cloth except for a cut edge, are bonded together. By using the opening that results from the absence of bonding at the edge of the reinforcement cloth, an object comprised of the primary and the secondary cloths and the reinforcement cloth can be turned inside out by passing the primary and secondary cloths through the opening at the cut edge of the reinforcement cloth.

Abstract: A base member which is formed into an approximately non-planar shape in a plan view so that the lateral width of the base member is relatively reduced is placed together with the air bag body into an air bag cover. Thereafter, the lateral width of the base member is increased by flattening the base member, so that engaging claws disposed on the base member engage with the air bag cover, thereby joining the base member to the air bag cover.
