## Abstract

The present invention provides an airbag cushion and a method of folding the same, in which the airbag cushion covers a lateral side and a front side of a seat by being deployed forward in a state in which the airbag cushion is folded at a lateral side of a seatback, a first lateral section of a lateral chamber, which is deployed from the lateral side of the seatback before the first lateral section reaches a passenger's shoulder, is folded by a tuck-in method that pushes the airbag cushion inward and folds the airbag cushion, and a second lateral section of the lateral chamber, which is deployed from the first lateral section while passing over the passenger's shoulder, is folded by an out-board roll method that folds the airbag cushion toward the outside of the passenger.

## Claims

### Claim 1

An airbag cushion stored folded at a lateral side of a seatback of a seat and configured to, when inflated, deploy forward to cover lateral and front sides of the seat, the airbag cushion including a lateral chamber divided into a plurality of lateral sections including:
a first lateral section stored tucked-in to push the airbag cushion inwardly and configured to, when deployed, extend forward from the lateral side of the seatback without reaching a shoulder of a passenger seated at the seat, and
a second lateral section stored out-board rolled to fold the airbag cushion away from the passenger and configured to, when deployed, extend forward from the first lateral section and beyond the passenger's shoulder.

### Claim 2 (depends on 1)

The airbag cushion of claim 1, wherein the plurality of lateral sections further includes a third lateral section stored in-board rolled to fold the airbag cushion toward the passenger and configured to, when deployed, extend forward from the second lateral section.

### Claim 3 (depends on 2)

The airbag cushion of claim 2, wherein the airbag cushion further includes a front chamber stored tucked in to push the airbag cushion inwardly and configured to, when deployed, extend laterally from the third lateral section.

### Claim 4

A method of folding an airbag cushion stored at a lateral side of a seatback of a seat, the airbag cushion configured to, when inflated, deploy forward to cover lateral and front sides of the seat and comprising a lateral chamber divided into a plurality of lateral sections including (1) a first lateral section configured to, when deployed, extend forward from the lateral side of the seatback without reaching a shoulder of a passenger seated at the seat and (2) a second lateral section configured to, when deployed, extend forward from the first lateral section and beyond the passenger's shoulder, the method comprising:
a first folding step of tucking-in the first lateral section to push the airbag cushion inwardly; and
a second folding step of out-board rolling the second lateral section to fold the airbag cushion away from the passenger.

### Claim 5 (depends on 4)

The method of claim 4, wherein:
the plurality of lateral sections of the lateral chamber further includes a third lateral section configured to, when deployed, extend forward from the second lateral section, and
the method further comprises a third folding step of in-board rolling the third lateral section to fold the airbag cushion toward the passenger.

### Claim 6 (depends on 5)

The method of claim 5, wherein:
the airbag cushion further comprises a front chamber configured to, when deployed, extend laterally from the third lateral section, and
the method further comprises tucking-in the front chamber to push the airbag cushion inwardly.

### Claim 7 (depends on 6)

The method of claim 6, wherein the airbag cushion is folded in an order of the front chamber, the third lateral section, the second lateral section, and the first lateral section.
