Abstract

A vehicle body 10 equipped with an airbag system has a side curtain airbag 20 provided on a roof side rail 12 . The side curtain airbag 20 includes: a bag body 51 that is disposed along the roof side rail 12 ; a central protector 59 that holds the bag body 51 ; and an inflator 52 that is configured to feed gas to the bag body 51 . The central protector 59 has a contact end part 65 that is opposed to a reinforcement member 48 with a gap L 2 left therebetween. The contact end part 65 is moved toward the reinforcement member 48 by a deployment force of the bag body 51 , and the contact end part 65 is thus supported by the reinforcement member 48.

First claim

The invention claimed is:

1. A vehicle body equipped with an airbag device, comprising:
a side panel and an upper panel each disposed in a wall part of said vehicle body to which said airbag device is installed, said upper panel being disposed inside a roof of the vehicle body;
a bag body that is disposed along said wall part of said vehicle body;
an inflator that is configured to feed gas to said bag body and deploy said bag body with the gas thus fed; and
a protector with a deformable body that holds said bag body so as to receive a deployment force of said bag body, the protector comprising a support part fastened to the side panel so as to support the said bag body and an edge part located on a vehicle inner side of the support part in a vehicle widthwise direction, the edge part facing upward and toward said upper panel and being movable toward said upper panel, wherein
said protector is configured to leave a gap between the edge part thereof and said upper panel when installed to said wall part, and
when said bag body is deployed, said protector is capable of deformation upon receiving the deployment force of said bag body such that said edge part moves toward said upper panel and becomes in contact with said upper panel, thereby causing said upper panel to support the protector along with said airbag body that is being deployed.

2. The vehicle body equipped with the airbag device according to claim 1 , wherein said protector comprises:
said edge part;
a receiving part that is provided outside said edge part in the vehicle widthwise direction and configured to hold said bag body when it is deployed; and
a curve part that is formed between said receiving part and said edge part and connects said receiving part and said edge part to each other.

3. The vehicle body equipped with the airbag device according to claim 2 , wherein
said vehicle body includes a body component that is provided inside said airbag device in the vehicle widthwise direction, and
said body component has a mounting part that is disposed inside said airbag device in the vehicle widthwise direction so as to be adjacent to said airbag device with a clearance therebetween and that is fastened to said vehicle body with a fastening member.

4. The vehicle body equipped with the airbag device according to claim 2 , wherein said edge part extends upward from an inner side end of said curve part such that a deployment force of the bag body causes said edge part to move upward and toward the upper panel.

5. The vehicle body equipped with the airbag device according to claim 1 , further comprising a roof panel of said vehicle body, wherein the upper panel is provided to the roof panel.
