An inflator for an air bag, includes, a tubular housing including a gas discharge portion, a first fixing member provided in an outer circumferential surface of the tubular housing for fixing the inflator to a vehicle, the first fixing member including a contacting surface fixed to the outer circumferential surface, and a non-contacting surface extending in a direction tangential to the outer circumferential surface from one end of the first fixing member without contacting the outer circumferential surface. The first fixing member has a rib that extends from the contacting surface to the non-contacting surface.

Inflator for air bag

An air bag apparatus having a constitution of developing an air bag folded to contain in a case to a rear side of a vehicle by making an expanding gas flow from a gas flow inlet in expanding to develop the air bag. The air bag is arranged with a through hole. The air bag is constituted by a ring-like member arranged with a lower expanded portion arranged with a gas flow inlet, an upper expanded portion arranged to an upper side of the lower expanded portion to communicate with a front side of the lower expanded portion, and a rear expanded portion arranged to connect to a rear part of the lower expanded portion and a rear part of the upper expanded portion at a surrounding of the through hole. The air bag is constituted to finish to expand by closing the through hole.

Air bag apparatus

In the airbag device of the present invention, a cylinder-shaped inflator includes a discharge side end portion having a plurality of gas discharge ports. The discharge side end is connected with the airbag utilizing a clamp by being inserted into a tubular gas inlet port of the airbag. Each of gas discharge ports includes a circumferential opening and an end face opening. The end face opening emits inflation gas in an axial direction of the inflator when the inflator is connected with the gas inlet port. Between each of the circumferential openings is a supporting plane for supporting an inner surface of the gas inlet port. The discharge side end includes a guide portion for redirecting inflation gas flowing from inside to directions perpendicular to the axis of the inflator when the gas inlet port is not connected with the inflator, such that inflation gas is discharged from the circumferential openings of the gas discharge ports. The airbag of the present invention dispenses with a diffuser and facilitates a connecting work of a cylinder-shaped inflator and an airbag.

Airbag device

The airbag device for pedestrian protection includes an airbag to be inflated in front of the vehicle and then be disposed between a pedestrian and the vehicle. The airbag includes a front cover portion and two fall preventing portions. The front cover portion covers the front side of the vehicle. The fall preventing portions cover the vicinities of the left and right edges of the top surface of the hood panel, respectively, and are projected upward so as to prevent the pedestrian from falling down. The airbag device for pedestrian protection is able to prevent the pedestrian mounted on a hood panel from falling down on road surface.

Airbag device for pedestrian protection

An air bag device comprises at the center a bag provided with a gas flowing orifice, a pad for receiving the bag in its folded state, an inflator arranged so as to permit gas to be jetted toward the gas flowing orifice of the bag and an inflator insertion hole into which a holding cylinder below the inflator can be inserted and further provided with a retainer for holding the inflator and the bag in their inner periphery and the pad in its outer periphery. The air bag device further includes a holding cloth surrounding the lower holding cylinder of the inflator and formed continuously below the gas flowing orifice of the bag, and a coupling is formed between the peripheral surface of the inflator and peripheral edge of the inflator insertion hole of the retainer.
