ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connecting structure between an airbag and an inflator used for an automobile or other vehicle. More particularly, the present invention relates to connecting structure between an airbag and a rod-type inflator having a rod-like shape in which gas is spouted out from one end of the inflator.
2. Description of the Related Art
A rod-type inflator is employed in a side airbag device arranged on a side of a vehicle seat, a head protecting airbag device of which an airbag is inflated on a side of a vehicle occupant's head, a torso/lap protecting airbag device (sometimes referred to as “inflatable belt device”) which is assembled in a webbing of a seat belt, or other airbag device.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a connecting structure between an airbag and a rod-type inflator which can provide high strength in the connection.
A connecting structure between an airbag and an inflator according to the present invention comprises: a rod-type inflator having gas ports formed in an end portion thereof; an airbag having a gas inlet fitted onto the inflator; a binding member for fixing the gas inlet of the airbag to the inflator; and a securing member for preventing the airbag from coming off the binding member.
The securing member may be disposed on the airbag and may comprise stitches which rise from the outer surface of the airbag.
The securing member may comprise a cloth or resin sewn to the outer surface of the airbag.
The securing member may comprise a bar member which is inserted into a through portion formed in the airbag.
In the connecting structure between the airbag and the inflator, the securing member is disposed on the airbag and the securing member is caught by the binding member when the airbag is about to come off the spaces between the binding member and the inflator, thereby preventing the airbag from further sliding in a detaching direction.
In the present invention, the inflator may have a groove formed in the outer surface thereof to extend in the circumferential direction and the securing member may comprise a portion of the airbag which is pushed into the groove.
The connecting structure between an airbag and an inflator according to the present invention may comprise a holder for fixing the inflator to a vehicle body. The holder may comprise a plurality of holding portions and the binding member may be arranged between the holding portions.
