Abstract

The disclosed airbelt apparatus may provide an airbelt capable of being connected to an anchor. The airbelt apparatus may comprise an anchor and an airbelt with a bag and a mesh webbing covering the bag. The anchor may have an opening, wherein only a tip end side of a portion of the airbelt is inserted into the opening. The portion of the airbelt can be the mesh webbing only or a combination of the mesh webbing and a webbing. The portion of the airbelt inserted into the opening can be folded back so as to overlap onto a base end side of the airbelt, and the tip end side of the portion of the airbelt and the base end side of the airbelt are stitched together.

Claims

1. An airbelt apparatus comprising:

an airbelt including a webbing, a bag connected to an end of the webbing, and a mesh webbing covering the webbing and the bag, wherein the airbelt is expandable by gas introduced into the bag;

an anchor including an opening, wherein only a tip end side of a portion of the airbelt is inserted into the opening; and

a protecting cover,

wherein the portion of the airbelt inserted into the opening is an extended portion of the mesh webbing that extends past the bag and the protecting cover, wherein the extended portion of the mesh webbing is folded back and overlaps onto a base end side of the airbelt,

wherein the tip end side of the portion of the airbelt and the base end side of the airbelt are stitched together, and

wherein the protecting cover covers the tip end side of the portion of the airbelt and the base end side of the airbelt that are stitched together and a tip end side of the webbing.

2. The airbelt apparatus according to claim 1, wherein the extended portion of the mesh webbing overlapping the base end side of the airbelt is stitched on the mesh webbing and the bag at the base end side of the airbelt.

3. The airbelt apparatus according to claim 2, wherein the extended portion of the mesh webbing overlapping the base end side of the airbelt is stitched on the webbing, the bag and the mesh webbing at the base end side of the airbelt.

4. The airbelt apparatus according to claim 1, wherein the webbing is connected to rear end sides of the mesh webbing and the bag.

5. The airbelt apparatus according to claim 4, wherein the rear end side of the mesh webbing extends out relatively longer toward the webbing in relation to the rear end side of the bag, and wherein the mesh webbing is stitched on the webbing at a portion in the mesh webbing, which is spaced apart from the rear end side of the bag at a predetermined distance.

6. The airbelt apparatus according to claim 5, wherein a stitching work for the mesh webbing and the webbing is performed such that a seam of the stitching work substantially extends in a direction across a longitudinal direction of the mesh webbing.

7. The airbelt apparatus according to claim 1, wherein a stitching work for the tip end side of the portion of the airbelt overlapping the base end side of the airbelt is performed such that a seam of the stitching work substantially extends in a direction across the longitudinal direction of the airbelt.

8. The airbelt apparatus according to claim 1, further comprising a gas generator.

9. An airbelt apparatus comprising:

an airbelt comprising a bag and a mesh webbing covering the bag, wherein the airbelt is expandable by gas introduced into the bag;

an anchor with an opening; and

a protecting cover,

wherein a tip end side of the mesh webbing extends out more than a tip end of the bag and a tip end of the protecting cover,

wherein only the tip end side of the mesh webbing is inserted into the opening,

wherein the mesh webbing is folded back so as to overlap onto a base end side of the airbelt,

wherein the tip end side of the mesh webbing and the base end side of the airbelt are stitched together, and

wherein the protecting cover covers the tip end side of the mesh webbing and the base end side of the airbelt that are stitched together.

10. The airbelt apparatus according to claim 9, wherein a tip end portion of the mesh webbing overlapping the base end side of the airbelt is stitched on the bag and the mesh webbing at the base end side of the airbelt.

11. The airbelt apparatus according to claim 9, wherein the airbelt further includes a webbing connected to rear end sides of the mesh webbing and the bag.

12. The airbelt apparatus according to claim 11, wherein the rear end side of the mesh webbing extends out relatively longer toward the webbing in relation to the rear end side of the bag, and wherein the mesh webbing is stitched on the webbing at a portion in the mesh webbing, which is spaced apart from the rear end side of the bag at a predetermined distance.

13. The airbelt apparatus according to claim 9, wherein a stitching work for the tip end side of the mesh webbing and the base end side of the airbelt is performed such that a seam of the stitching work substantially extends in a direction across the longitudinal direction of the mesh webbing.
