Abstract

A head-protecting airbag device includes: an airbag including: an airbag body; and a connecting tab connected with a mounting bracket, wherein the mounting bracket includes: a mounting piece mounted on the body with a fixing means; and a connecting piece formed to project to both sides from a lower end of the mounting piece, and connected with the airbag; in the connecting tab, an insertion hole, into which the mounting piece is inserted, is disposed in a folded portion; the connecting tab includes a front side portion and a back side portion which extend from the folded portion to the airbag body and cover a font side and a back side of the connecting piece; and a loop coupling portion is disposed in a position where the mounting piece having the connecting piece stored in the connecting tab is prevented from coming off the insertion hole.

Claims

1. A head-protecting airbag device comprising:

an airbag which is stored in an upper edge on an indoor side of a vehicle and is inflated to cover an indoor side of a window when inflation gas is allowed to flow inside; and

a mounting bracket which mounts an upper edge of the airbag on a body on an upper edge side of the window, wherein;

the airbag includes;

an airbag body; and

a connecting tab having a loop-shape, protruding upward from an upper edge of the airbag body, being connected with the mounting bracket and having flexibility;

the mounting bracket includes;

a mounting piece being mounted on the body with a fixing means; and

a connecting piece being formed to be wider than the mounting piece to project to both sides from a lower end of the mounting piece, and being connected with the airbag;

in the connecting tab, an insertion hole, into which the mounting piece of the mounting bracket is inserted, is disposed in a folded portion of a tip separated from the airbag body;

the connecting tab includes a front side portion and a back side portion which extend from the folded portion to the airbag body and cover a font side and a back side of the connecting piece; and

a loop coupling portion of the front side portion and the back side portion which form the connecting tab in a loop shape is disposed in a position where the mounting piece of the mounting bracket having the connecting piece stored in the connecting tab is prevented from coming off the insertion hole.

2. The head-protecting airbag device according to claim 1, wherein

the loop coupling portion of the connecting tab is disposed in a position, which is separated from the upper edge of the airbag body, of the front side portion and the back side portion.

3. The head-protecting airbag device according to claim 1, wherein

the loop coupling portion of the connecting tab is disposed in a position, which is in the airbag body, of the front side portion and the rear side portion as a position where the front side portion and the back side portion are couplable with the airbag body.

4. The head-protecting airbag device according to claim 2, wherein

the loop coupling portion of the connecting tab is formed of a linear sewing portion along a projecting direction of the connecting piece from the mounting piece of the mounting bracket.

5. The head-protecting airbag device according to claim 3, wherein

the loop coupling portion of the connecting tab is formed of a linear sewing portion along a projecting direction of the connecting piece from the mounting piece of the mounting bracket.

6. The head-protecting airbag device according to claim 2, wherein

the loop coupling portion of the connecting tab is formed such that linear sewing portions are provided in parallel to each other to be orthogonal to a projecting direction of the connecting piece from the mounting piece of the mounting bracket.

7. The head-protecting airbag device according to claim 3, wherein

the loop coupling portion of the connecting tab is formed such that linear sewing portions are provided in parallel to each other to be orthogonal to a projecting direction of the connecting piece from the mounting piece of the mounting bracket.
