## Abstract

The present invention relates to a seat airbag apparatus for a vehicle, in which a raw cushion fabric 210 provided in the form of a single flat panel is coupled by sewing to an inner cushion part 110 provided in the form of a flat panel, and a front cushion 200 is formed by using the raw cushion fabric 210 provided in the form of a flat panel. Therefore, the sewing coupling may be easily and smoothly performed, and particularly the tolerance in respect to the sewing coupling may be reduced, thereby improving quality.

## Claims

### Claim 1

A seat airbag for a vehicle, comprising:
a lateral cushion including:
an inner part configured to face in a first direction toward a passenger when the lateral cushion is deployed;
an outer part superimposed with the inner part and configured to face in a second direction opposite to the first direction when the lateral cushion is deployed, wherein an outer periphery of the outer part is coupled to that of the inner part; and
a first inner space between the inner and outer parts, wherein the lateral cushion is configured to inflate and cover a side of the passenger when airbag gas is supplied to the first inner space; and
a front cushion having a second inner space connected to the first inner space of the lateral cushion and configured to inflate and cover a front of the passenger when the airbag gas is supplied to the second inner space,
wherein an outer periphery of a front portion of the lateral cushion is coupled to an outer periphery of the front cushion,
wherein the front cushion includes a raw cushion fabric provided in a form of a flat panel, and
wherein the raw cushion fabric is folded in a pocket shape and is coupled to the inner part.

### Claim 2 (depends on 1)
