Abstract

In an air belt device which has the gas-supply portion, such as an inflator, fixed therein, a connection between an air belt and a gas supply portion is simplified. A lap anchor 13 coupled to an end of a lap bag 15 is pivotally supported by a support shaft 13p such that the lap anchor 13 can turn back and forth with respect to a seat frame 2. The inflator 12 is fixed to be disposed on a side face of the seat frame 2. A substantially tubular gas-introducing path extends from the lap bag 15. The gas-introducing path 16 is connected to a pipe 17 extending from the inflator 12 in a slack state.

Claims

1. An air belt device comprising a gas supply portion having an inflator, and a bag to which gas is supplied from the gas supply portion to inflate the bag, the bag including a bag body folded into a belt shape, and a tubular gas-introducing path extending from the bag body,

wherein the gas-introducing path is connected to the gas supply portion in a slack state.

2. The air belt device according to claim 1, wherein an end of the gas supply portion is inserted into the gas-introducing path, a soft tube is connected to the end of the gas supply portion, and the gas is supplied from the gas supply portion through the soft tube to the bag body.

3. The air belt device according to claim 1, wherein the gas supply portion is the inflator.

4. The air belt device according to claim 1, wherein the gas supply portion includes the inflator and a pile connected to the inflator.

5. The air belt device according to claim 1, wherein the bag is a lap bag and the gas supply portion is disposed on a seat frame of a seat.

6. The air belt device according to claim 5,

wherein the lap anchor is attached to the seat frame so as to turn back and forth with respect to the seat, and

the lap bag is connected to the lap anchor.

7. The air belt device according to claim 6,

wherein the gas supply portion is arranged in front of the lap anchor, and

even when the lap anchor turns to a backward turn limit, the gas-introducing path is in a slack state.
