Abstract

A side airbag is inflated and deployed in a space between a side wall portion of a vehicle body and an occupant seated on a seat disposed inside the vehicle body. The side airbag includes an airbag body having a base end side and a tip end side opposite to the base end side, an accordion-shape folded portion in the airbag body folded into an accordion shape when folded, and a roll-shape folded portion in the airbag body folded into a roll shape when folded, at one side of the according-shape folded portion.

Claims

1. A side airbag to be inflated and deployed in a space between a side wall portion of a vehicle body and an occupant seated on a seat disposed inside the vehicle body, comprising:

an airbag body having a base end side and a tip end side opposite to the base end side,

an accordion-shape folded portion in the airbag body folded into an accordion shape when folded, and

a roll-shape folded portion in the airbag body folded into a roll shape when folded, at one side of the accordion-shape folded portion.

2. The side airbag according to claim 1, wherein the accordion-shape folded portion is arranged at the base end side, and the roll-shape folded portion is arranged at the tip end side under the accordion-shape folded portion to thereby form an elongated shape.

3. The side airbag according to claim 1, wherein said airbag body further includes an inward-folded portion where a bag outer edge portion at the tip end side is folded inwardly between two outer panel portions of the side airbag.

4. The side airbag according to claim 1, further comprising a double folded-back portion where an end portion of the airbag body folded into an elongated shape by the according-shape folded portion and the roll-shape folded portion is folded toward one side, and further folded toward the other side.

5. The side airbag according to claim 1, wherein said airbag body includes a first chamber forming a first bag portion for receiving a chest portion of the occupant, and a second chamber forming a second bag portion for limiting a movement of a waist portion of the occupant.

6. The side airbag according to claim 5, wherein the first bag portion and the second bag portion are connected at the base end side.

7. The side airbag according to claim 1, further comprising a through hole for inserting an inflator supplying gas into an inside of the airbag body, a first cover member disposed at one side of the through hole for covering the passing through hole from an outside of the airbag body, and a second cover member disposed at the other side of the through hole for covering the through hole from the outside of the airbag body.

8. A side airbag apparatus comprising:

the side airbag according to claim 1;

an inflator supplying the gas for inflating and deploying the side airbag; and

a casing for housing the side airbag and the inflator.

9. A motor vehicle seat comprising:
