Abstract

A mounting structure of air bag device on vehicle body includes: a seat side block long in a vertical direction disposed on a side of a backrest portion of a seat; and an air bag unit including an inflator that injects high pressure gas at a time of application of an impact and a bag body that is deployed upon receiving the high pressure gas of the inflator. The airbag unit is built in the seat side block. The air bag unit along with the seat side block is mounted on a vehicle body side member. Retaining pieces are protrudingly provided in a retainer of the seat side block that holds the inflator and are inserted in openings of the vehicle body side member.

First claim

What is claimed is:

1 . A mounting structure of air bag device on vehicle body, the mounting structure comprising:
a seat side block disposed generally in a vertical direction on a side of a backrest portion of a seat and having a longitudinal direction along the vertical direction; an air bag unit housed in the seat side block and comprising an inflator that injects high pressure gas at a time of application of an impact and a bag body that is deployed upon receiving the high pressure gas of the inflator, the air bag unit and the seat edge block being mounted on a vehicle body side member; and a rotation restriction member provided to the vehicle body side member in a vicinity of the inflator of the seat edge block in a manner that restricts a rotation of the air bag unit around an axis substantially parallel to the longitudinal direction.

2 . The mounting structure of air bag device on vehicle body according to claim 1 ,
wherein the seat side block comprises a housing having a recessed portion in which the air bag unit is housed, and a metal retainer that is provided to a backside of the recessed portion of the housing and supporting the inflator housed in the recessed portion, and the rotation restriction member comprises one or more support members that protrude from the retainer and extend to the vehicle body side member, the support members being inserted in one or more openings of the vehicle body side member.

3 . The mounting structure of air bag device on vehicle body according to claim 2 ,
wherein the one or more support members are provided at a plurality of locations spaced apart in a direction crossing the longitudinal direction of the seat side block.

4 . The mounting structure of air bag device on vehicle body according to claim 3 ,
wherein at least one of the one or more support members is bent thereof in a manner that engages with an edge of the one or more openings.

5 . The mounting structure of air bag device on vehicle body according to claim 2 ,
wherein the seat side block has a first engagement portion and a second engagement portion, the first engagement portion is inserted in the vehicle body side member to engage therewith, the first engagement portion being movable from a disengagement position to an engagement position in the longitudinal direction, the second engagement portion is fastened and fixed to the vehicle body side member in a direction crossing the longitudinal direction in a state where the first engagement portion is in the engagement position, and the one or more openings of the vehicle body side member have such a length in the longitudinal direction that the first engagement portion is movable from the disengagement position to the engagement position in a state where the one or more support members are inserted in the one or more openings of the vehicle body side member.
