PROBLEM TO BE SOLVED: To efficiently prevent a seat skin material having a weak part from stretching too much and deforming owing to an expanding air bag by a low extending member, and to conceal a seam part between the skin material and the low extending member. SOLUTION: A slit 21a is formed on a seat skin material 32 of a side end part 2L of a seat bag 2, and closed by suturing. An air bag 13, expanding from an air bag unit U in the side end part 2L, spreads to the outside of a seat through the slit 21a. Between the skin material 32 and a cushion member 31 formed on the back side thereof, low extending members 51, 52 extending by lower degree than the skin material 32 are arranged. The skin material 32 is provided with a folded back part to the back side on the weak part 21. The one end portions of the low extending member 51, 52 are joined to only the folded back parts of the skin material, and the other end portions are joined to reinforce members (frame) 42, 43a in the seat bag 2. |
