PROBLEM TO BE SOLVED: To ensure the thickness of a pad material near an air bag unit to ensure cushioning performance by providing, in a part near the air bag unit within a seat, a guide member for guiding an air bag in a prescribed expanding direction when the air bag is expanded in a specified direction. SOLUTION: An air bag unit 20 is arranged in a housing part 25 formed in a pad material 9 toward a specified direction inclined left about 45 deg. to the front which is a prescribed expanding direction for expanding an air bag 23 so that the thickness of the pad material 9 is not reduced. This device has a deflecting plate 26 for guiding the air bag 23 so as to be expanded forward in the expansion of the air bag, and the deflecting plate 26 is set to a height about 2 times the height of the air bag unit 20, and extended from a seat back frame 8 forward so as to be laid along about the left end of a swollen part 3a, and its rear end is fixed to the seat back frame 8 by spot welding. Thus, cushioning performance can be ensured. |
