HEAD PROTECTION AIRBAG APPARATUS
First Claim
1. A head protection airbag apparatus comprising:
- an airbag which is configured to be folded and accommodated on an upper edge side of a window on an inner vehicle side, of which the upper edge side is fixedly attached onto a vehicle body side, and which allows inflation gas to flow in to deploy and inflate so as to protrude downward and cover the inner vehicle side of the window; and
an inflator which supplies the inflation gas to the airbag,wherein the airbag includes a flexible bag-like airbag body of which the upper edge side is fixed to the vehicle body side on the upper edge side of the window at a plurality of places along a front-rear direction, and a flexible sheet material-made tension cloth of which a base portion side is joined to one end portion side in the front-rear direction in the airbag body and of which a leading end side is fixed to the vehicle body side on a peripheral edge of the window away from the end portion of the airbag body,wherein the airbag body includes an end side inflation portion arranged at an end portion in the front-rear direction which becomes the tension cloth side at the time of completion of inflation,wherein the end side inflation portion is divided from other general inflation sections in the airbag body by a division portion which is positioned on a central side of the airbag body in the front-rear direction and arranged substantially along a vertical direction, andwherein the tension cloth is disposed in an arranged state so as to cover the inner vehicle side of the end side inflation portion, allows the base portion side to be joined to an end edge side of the end side inflation portion in the front-rear direction, is inserted into a slit formed in the division portion while being inverted so as to cover an outer vehicle side of the end side inflation portion, and allows the leading end side to be fixed to the vehicle body side.
