Problems solved by technology

[0013] However, for the connection structure between the interface part and the inflator using only the clamp, in the case where the output of the inflator increases with the volume of the airbag, there is a risk that the interface part will be damaged when the inflator is triggered. Disengaged from the inflator, therefore, can still be improved in terms of increased connection strength

Abstract

The invention discloses a head protective airbag, which can be folded and contained at the upper of vehicle window and be unfolded downward and expanded from the upper of vehicle window to cover the inner side of vehicle window. In the airbag, expansion air longitudinally in an air channel, a plurality of parallel air chambers are arranged below the air channel, which can unfold and expand when being injected via expansion air. The ones of parallel air chambers that needs quick unfolding are arranged with front and back separation portions to set the ascending separation portion of the air inthe air channel to form an inlet between the end extended upward from the lower flange and the end of the horizontal portion of the descending separation portion.

Description

technical field [0001] The present invention relates to an airbag device comprising an airbag connected to a housing portion of an automobile. In particular, the present invention relates to a head protection airbag configured to house the folded airbag in the upper part of a vehicle window in a state where the outer periphery of the airbag is covered by a synthetic resin protective cover after folding, so that when inflation gas is injected therein, the The airbag is inflated to protrude downward from the accommodating portion so as to cover the inside of the window. Background technique [0002] Conventionally, a head protection airbag which is completed to inflate to cover the inner side of a vehicle window is made to include: a gas injection portion which inflates by allowing inflation gas to be injected thereinto to separate the inner wall portion and the outer wall portion from each other; A non-injection portion that keeps the inner and outer wall portions joined to ...
