## Abstract

A side airbag device with a base member for an inflator to be easily fixed thereto, and a method for manufacturing same is provided. The side airbag device includes: an airbag; an inflator configured to supply the airbag with gas; a base member configured to accommodate the airbag and the inflator, and to be fixed to a vehicle body; an outer covering member configured to cover at least a front side of the base member to form a front-facing interior surface; and a mounting bracket. The mounting bracket includes an inflator fixing portion to which the inflator is fixed and a base member fixing portion which is located in a position different from a position of the inflator fixing portion and fixed to the base member. The base member includes, at a left or right side portion thereof, a bracket fixing portion to which the mounting bracket is fixed.

## Claims

### Claim 1

A side airbag device disposed between a vehicle body and a seat, the side airbag device comprising:
an airbag;
an inflator configured to supply the airbag with gas; and
a base member fixed to the vehicle body, the base member having a storage space in which the airbag and the inflator are accommodated;
wherein the base member comprises:
a wire frame made of a metal rod; and
a guide plate made of a metal plate and located on a storage-space side of a front edge portion of the wire frame, and
wherein the guide plate is fixed to the front edge portion of the wire frame.

### Claim 2 (depends on 1)

The side airbag device according to claim 1, wherein
the base member comprises an outer portion located laterally outward, with respect to the vehicle body, relative to the airbag, and
the guide plate comprises a first guide plate provided along a front edge portion of the outer portion.

### Claim 3 (depends on 2)

The side airbag device according to claim 2, wherein the first guide plate is provided along a length of the outer portion from an upper end to a lower end of the outer portion.

### Claim 4 (depends on 2)

The side airbag device according to claim 2, wherein the first guide plate includes, at a rear end portion thereof, a flange extending outward in a lateral direction as defined with respect to the vehicle body.

### Claim 5 (depends on 4)

The side airbag device according to claim 4, wherein the flange is in contact with the vehicle body.

### Claim 6 (depends on 2)

The side airbag device according to claim 2, wherein
the base member comprises an inner portion located laterally inward, with respect to the vehicle body, relative to the airbag, and
the guide plate comprises a second guide plate provided along a front edge portion of the inner portion.

### Claim 7 (depends on 6)

The side airbag device according to claim 6, wherein the second guide plate is provided along a length of the inner portion from an upper end to a lower end of the inner portion.

### Claim 8 (depends on 6)

The side airbag device according to claim 6, wherein the second guide plate is parallel to the first guide plate.

### Claim 9 (depends on 1)

The side airbag device according to claim 1, further comprising:
an outer covering member configured to cover at least a front side of the base member; and
a hook member provided at an end portion of the outer covering member to fasten the outer covering member,
wherein the base member includes an outer covering anchorage portion on which the hook member is hooked, the outer covering anchorage portion being located on a side of the guide plate opposite to the storage space.
