Abstract

A curtain airbag apparatus is provided with a bag disposed along the upper edge of an opening of a vehicle body in a folded state, a plurality of protectors disposed along a lengthwise direction of the bag, which prevent the bag from interfering with the vehicle body; and brackets intervening between the bag and the vehicle body, which attach the bag to the vehicle body and support the protectors, wherein protectors adjacent to each other are spaced from each other in the lengthwise direction of the bag.

Claims

1. A curtain airbag apparatus comprising:

a bag disposed along an upper edge of an opening of a vehicle body in a folded state;

a plurality of protectors disposed along a lengthwise direction of the bag, said protectors partially surrounding said bag and preventing the bag from interfering with the vehicle body; and

a plurality of brackets intervening between the bag and the vehicle body, at least one of said plurality of brackets partially surrounding an associated one of the protectors and serving to attach the bag to the vehicle body and support the associated protector;

wherein protectors adjacent to each other are spaced from each other in a lengthwise direction of the bag, and said bag projects beyond said associated protector and is directly affixed to said at least one bracket.

2. The curtain airbag apparatus of claim 1, wherein each of said protectors extend between two of said plurality of brackets.

3. The curtain airbag apparatus of claim 1, wherein the bag further comprises a lug portion and the associated protector defines a slit through which the lug portion extends, said lug portion being directly secured to said at least one bracket.

4. The curtain airbag apparatus of claim 1, wherein said associated protector includes a bracket portion defining a stopping hole, wherein the at least one bracket further includes a stopping finger that is received in the stopping hole, whereby the associated protector is secured to the at least one bracket by engagement of the stopping finger with the bracket portion.
