Abstract: In a head portion protecting air bag apparatus in which an air bag (11) housed along a roof side rail (21) is inflated and deployed in a curtain-like shape along a vehicle compartment side wall by a gas supplied from an inflator (14) so as to protect a head portion of an occupant, the air bag (11) is provided with a front seat inflating portion (11c), a rear seat inflating portion (11d), and a gas passage (11b) communicated with inflating chambers of both of these inflating portions (11c, 11d), a gas supply port (11a) for supplying the gas supplied from the inflator (14) downward is provided corresponding to the gas passage (11b), and an auxiliary inflating chamber (11e1) is provided corresponding to the gas supply port (11a).

Abstract: In an inflator including a plurality of gas feed portions (gas chambers for storing high-pressure gases, gas sealing plates for sealing the gas chambers, and initiators for fracturing the gas sealing plates) in a single casing, an airtight partition integrated with the casing airtightly separates the gas chambers of the gas feed portions from each other, and the casing is provided with a plurality of gas feed passages that individually communicate with the gas chambers.

Abstract: An air bag system is provided which includes an inflator serving as a gas generator, an air bag which is stored in a folded state in a certain portion of a vehicle and is adapted to be inflated by the gas supplied from the inflator to protect a vehicle occupant or occupants, and a diffuser serving to guide gas from the inflator into the air bag. In the air bag system, a preliminary inflatable portion is formed in a gas supply port of the air bag and a gas distribution portion formed in the end of the diffuser is arranged within the preliminary inflatable portion.

Abstract: A structure absorbs impact energy in an upper vehicle body portion provided with a vehicle body structural member and an interior trim spaced inward from the structural member. The structure includes an energy absorbing member disposed in the interval between the structural member and the interior trim and extending along the structural member in a lengthwise direction of the structural member, and a spacer substantially filling a gap formed between the energy absorbing member and the interior trim. The energy absorbing member is formed so that a section thereof taken on an imaginary plane perpendicular to the lengthwise direction has a substantially uniform shape along the lengthwise direction. The energy absorbing member may be an extended pipe or a hybrid pipe including a core member formed from a metal foil, and sheets of a different material laminated on opposite surfaces of the core member.

Abstract: A head protection airbag system for a vehicle with a roof side rail includes an airbag stored in the vehicle along the roof side rail, and an inflator mounted to the roof side rail. The inflator is operable to supply a gas that inflates the airbag so that the airbag deploys into a curtain-like shape along a side wall of a passenger compartment. A bracket, which is formed of an energy absorbing material, is interposed between the roof side rail and the inflator for mounting the inflator to the roof side rail such that the inflator is movable over a predetermined distance, whereby an external force applied to the inflator is mitigated by the bracket.

Abstract: A structure for securing a hollow energy absorber to a vehicle body structural member includes a joint member. The joint member has two fitting end portions fittable to an end portion of one of two adjacent energy absorbers and an end portion of the other energy absorber, respectively, the end portions facing each other. The joint member is mountable to a structural member.

Abstract: An automotive impact energy absorbing structure has a structural member having an inner panel, and an interior member spaced from the inner panel by an interval extending therefrom toward the inside of a compartment A hollow body is disposed within the interval. Impact energy applied to the hollow body from inside the compartment is absorbed by deformation of the hollow body.

Abstract: An impact absorbing member is provided that can absorb impact energy in an upper vehicle body portion. The member may be provided in n interval between a vehicle body structural member and an interior trim spaced from the structural member. The energy absorbing member is a hybrid pipe having a metal foil core member and sheets laminated on opposite surfaces of the core member, each sheet being formed from a material other than metal. The core member and the sheets on the opposite surfaces of the core member are shaped so that the hybrid pipe has protruded portions and recessed portions that are contiguous in a direction of an axis of the hybrid pipe. Various configurations are provided to adjust and control energy absorbing characteristics of the energy absorbing member.
