Head protecting airbag device

摘要

A head protecting airbag device includes: an airbag configured to cover a window of a vehicle; a winding band wound around a folded body which is formed by folding the airbag, the winding band including: an attachment portion being pressed and locked to an attachment target portion; a band body wound around the folded body; an engaging claw portion formed at one end of the band body; and an engaging target portion disposed at the other end of the band body; and a pressing portion, having a pressing operation surface configured to press-fit the engaging claw portion into an engaging concave portion, disposed at a claw-side end of the band body, wherein the attachment portion is disposed at a concave-side end of the band body so that the press-fit direction to the attachment target portion at the time of locking is substantially perpendicular to the pressing operation surface.

1. A head protecting airbag device comprising:
an airbag configured to cover a window of a vehicle when the airbag is unfolded and inflated, the airbag being folded and received on a vehicle-inside upper edge side of the window; a winding band, formed of flexible synthetic resin, configured to prevent folding collapse of the airbag, wound around a folded body which is formed by folding the airbag so as to release a wound state of the airbag in unfolding and inflating the airbag, the winding band including:
attachment portion being pressed and locked to an attachment target portion to attach the folded body to the attachment target portion;a band body having a belt-like shape, the band body being wound around the folded body;an engaging claw portion formed at one end of the band body; andan engaging target portion disposed at the other end of the hand body, the engaging target portion including an engaging concave portion into which the engaging claw portion is inserted to engage therewith; and a pressing portion having a pressing operation surface configured to press-fit the engaging claw portion into the engaging concave portion, the pressing portion being disposed at a claw-side end of the band body so that the pressing operation surface is substantially perpendicular to a press-fit direction of the engaging claw portion, wherein the attachment portion is disposed at a concave-side end of the band body so that the press-fit direction to the attachment target portion at the time of locking is substantially perpendicular to the pressing operation surface so as to press and lock the pressing operation surface to the attachment target portion.
