Abstract

A side airbag apparatus is provided between a vehicle body and a back seat, and includes a base housing configured to house an airbag and an inflator, a base member having upper and lower base attachment portions provided to sandwich the base housing in an upper-to-lower direction and attached to a portion of the vehicle body, and a retainer member configured to hold the base housing from a vehicle back side. Right and left engagement claws at an upper end of a back wall of the retainer member are arranged to engage respectively with engagement holes provided at a portion of the vehicle body on the vehicle back side. A virtual plane passing through the upper and lower base attachment portions and extending along a vehicle front-to-back direction passes between the right and left engagement claws.

First claim

What is claimed is:

1. A side airbag apparatus installed in a vehicle between a door of the vehicle and a back seat of the vehicle, the side airbag apparatus comprising:
an airbag that is inflatable;
an inflator configured to supply gas into the airbag;
a base member comprising,
a base housing configured to house therein the airbag in a folded state and the inflator, and
attachment portions attached to a vehicle body provided between the door of the vehicle and the back seat; and

a retainer member disposed along a back side of the base housing and configured to hold the base housing from the back side thereof in a vehicle front-to-back direction,
wherein the retainer member on a back side thereof has right and left engagement claws at locations apart from each other in a vehicle width direction, the right and left engagement claws protruding toward the vehicle body which faces the back side of the retainer member and being configured to engage respectively with engagement holes formed at the vehicle body.

2. The side airbag apparatus according to claim 1 ,
wherein the retainer member comprises,
a back wall elongated generally in a vehicle upper-to-lower direction and disposed along the back side of the base housing, the back wall having side edges in the vehicle width direction, and
right and left side walls each extending forward from one of the side edges of the back wall in the vehicle front-to-back direction, and

wherein the right and left engagement claws are provided at one of vertical ends of the back wall, the vertical ends being vertical in the vehicle front-to-back direction and in the vehicle width direction.

3. The side airbag apparatus according to claim 2 ,
wherein the base member comprises as the attachment portions upper and lower base attachment portions such that the base housing is disposed between the upper and lower base attachment portions in the vertical direction and along a virtual plane which passes through each of the upper and lower base attachment portions and extends along the vehicle front-to-back direction, and
wherein the right and left engagement claws are positioned such that the virtual plane passes between the right and left engagement claws.

4. The side airbag apparatus according to claim 3 ,
wherein the vehicle body further comprises a lower engagement hole at a position lower than the engagement holes which engage with the right and left engagement claws,
wherein the right and left engagement claws are integral portions of the retainer member such that an upper vertical end of the back wall has been partially cut and bent up so as to form each of the right and left engagement claws, and
wherein the retainer member further comprises a lower engagement claw that is provided at a position lower than the right and left engagement claws and corresponding to the position of the lower engagement hole of the vehicle body, thereby engaging therewith.

5. The side airbag apparatus according to claim 4 , wherein the lower engagement claw is provided at one of the side edges of the back wall in such a position that the one of the side edges is closer to the virtual plane than an other of the side edges in the vehicle width direction.

6. The side airbag apparatus according to claim 2 , further comprising:
a shaft member provided with the inflator for assembling the inflator, the base housing, and the retainer member together, the shaft member being provided with an assembly member engageable with the shaft member; and
a hole formed at each of the base housing and the retainer member and axially aligned with the shaft member so as to allow the shaft member to penetrate therethrough from a side of the inflator and engage with the assembly member at an axial end of the shaft member,
wherein the hole of the retainer member is formed in at least one of the side walls thereof such that the shaft member is assembled at the at least one of the side walls.
