Head-protecting airbag device
First Claim
1. A head-protecting airbag device having an airbag that is adapted to be housed in a folded-up configuration in a housing area located at an upper periphery of a window of a vehicle on an inboard side of a vehicle, the airbag being inflatable with an inflation gas and deployable over an inboard side of the window, the airbag comprising:
- a folded-up body that is a state of the airbag obtained as a result of folding the airbag in such a fashion as to bring a lower edge of the airbag close to an upper edge of the airbag, the folded-up body being so elongated as to extend generally along a front and rear direction of a vehicle, and being to be wrapped by a tearable tape member that is formed into a flexible band and is wrapped generally along a circumferential direction of the folded-up body in order to prevent a folded-up configuration of the folded-up body from collapsing;
a gas admissive portion that is inflatable with an inflation gas in such a fashion as to separate an inboard side wall deployable at an inboard side from an outboard side wall deployable at an outboard side;
a non-admissive portion that admits no inflation gas, the non-admissive portion including a peripheral portion that constitutes an outer peripheral edge of the airbag; and
displacement-preventing means for preventing the tape member from being displaced relative to the folded-up body, the displacement-preventing means being formed at an upper end region of the peripheral portion which will be an upper edge of the airbag at deployment, the displacement-preventing means comprising a recessed region or a projecting region that is formed on the airbag itself at least either in front of or at the rear of a location at which the tape member is to be wrapped so as to be engageable with an end edge of the tape member and prevent the tape member from being displaced.

Abstract
An airbag is housed in a housing area in the shape of a folded-up body which is obtained as a result of folding the airbag by bringing the lower edge close to the upper edge and elongated in a front and rear direction. A displacement-preventing means is provided at a peripheral portion of the airbag constituting an outer peripheral edge of the airbag for preventing a tape member wrapped around the folded-up body from supping against the folded-up body. The means is formed at an upper end region of the peripheral portion which will be an upper edge of the airbag at deployment and at least either in front of or at the rear of the tape member. The means is comprised of a recessed region or a projecting region that is formed on the airbag itself so as to be engageable with an end edge of the tape member.
