Abstract
An automobile seat is provided with a side impact air bag accommodated within a seat back. To permit prompt burst-out of the side impact air bag precisely at a predetermined position in a predetermined direction without the need for the arrangement of a member different in nature from a surface of the seat back on the surface of the seat back, an air bag module is arranged within a cushion pad of the seat back. Further, the cushion pad is provided, on a surface of a surrounding portion thereof with which the air bag is brought into contact upon spreading, with a guide member which increases breaking strength of the cushion pad and specifies the cushion pad to be broken at a break portion under inflating force of the air bag.
