VEHICLE SEAT PROVIDED WITH SIDE AIRBAG DEVICE

摘要

The present invention can improve initial passenger restraining performance of an airbag, and reduce 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.
