Abstract

An air bag device includes an air bag cushion to expand at a lateral surface of a seat back, a first tether that extends through an upper region of the air bag cushion from a lower portion of the seat back to define a loop, and a second tether connected to the first tether and that extends through the air bag cushion at an upper portion of the seat back.

Claims (16)

1 . An air bag device, comprising:

an air bag cushion configured to expand at a lateral surface of a seat back;

a first tether that extends through an upper region of the air bag cushion from a lower portion of the seat back to define a loop; and

a second tether that extends from an upper portion of the seat back and is connected to the first tether,

wherein a first through hole is disposed in a front end portion of the air bag cushion, and the first tether extends through the first through hole,

wherein a second through hole is disposed in a center portion of the air bag cushion, and the first tether sequentially extends through the first through hole and the second through hole and is mounted on the lower portion of the seat back,

wherein the first tether comprises a first portion connected between a first inflator stud disposed at the lower portion of the seat back and the second through hole, and

wherein the second tether is directly connected to the first portion of the first tether.

2 . The air bag device of claim 1 , wherein two end portions of the first tether are mounted on the lower portion of the seat back, and

an end portion of the second tether is mounted on the upper portion of the seat back such that the first tether and the second tether are mounted on the upper and lower portions of the seat back at three points to support the air bag cushion.

3 . The air bag device of claim 1 , wherein the first tether comprises:

a second portion connected between the second through hole and the first through hole; and

a third portion connected between the first through hole and a second inflator stud disposed adjacent to the first inflator stud.

4 . The air bag device of claim 1 , wherein a point at which the second tether is mounted on the seat back is positioned higher than the first through hole and the second through hole.

5 . The air bag device of claim 1 , wherein the second tether is connected to the first tether, which extends from an inner lateral surface of the air bag cushion.

6 . The air bag device of claim 1 , wherein a third through hole is disposed in a rear end portion of the air bag cushion and the second tether extends through the third through hole.
