Problems solved by technology

[0009] However, in the case of the above-mentioned prior art, the bracket, which is a component that is not originally related to the side airbag device, is required, and the number of components increases.
In addition, since the bracket is provided, the installation work of the seat back side frame including the side airbag device and the seat back panel is complicated accordingly.
In addition, the above-mentioned increase in the number of parts and the complexity of the installation man-hour lead to an increase in cost

Abstract

The present invention provides a vehicle seat provided with a side airbag device and capable of improving the initial passenger restraining performance of an airbag, and reducing costs. A seat backboard (16) made of a plastic material is fitted from the rearward side of the seat into a seat frame (26) of a seat back frame (14). A case section (102) for accommodating a side airbag device (100) secured to the outside surface of the side frame (20) is integrally formed in the side section of the seat backboard (16) on the outer side in the seat width direction. The presence of a side wall section (102B) of the case section (102) inhibits the side airbag (106) from roundly bulging to the outer side of the seat back in the initial stage of expansion.

Description

technical field [0001] The present invention relates to a vehicle seat provided with a side airbag device. Background technique [0002] Patent Document 1 below discloses a vehicle seat including a side airbag device that inflates and deploys a side airbag between a door trim of a side door and a side portion of a seated passenger during a side collision. In this prior art, there is provided a bracket that covers a part of the side airbag from the vehicle rear side and is open on the front side. The bracket is fixed to the outer side in the seat width direction of the seat back side frame, and the seat back board is fixed to the seat back side frame via the bracket. In addition, when viewed from the side of the seat, the front end of the airbag case is located on the vehicle front side with respect to the front ends of the seat back panel and the bracket. According to the above structure, since the seat back board is fixed to the seat back side frame via the bracket, the s...
