PROBLEM TO BE SOLVED: To sufficiently provide breakage of a projecting port of a trim cover in case of expansion of a side air bag by directly and fixedly connecting a side face rear end of a gusset of a trim cover to fixing member of a squab. SOLUTION: A suspension wire 40 extendingly arranged in the vertical direction of a squab 12 is provided integrally with the boundary part between an end plate part, 14b-1 and a frame part, 14b-2 of a trim cover under an integral sewing of a covering cloth 42 and fixedly connected to a fixing member such as a squab frame 8. A hook piece 44 provided inside the trim cover 14 in the side rear end of the gusset part 14a is locked by a lock piece 46 provided in the squab frame 28 and the side rear end of the gusset part 14a is directly and fixedly connected to the squab frame 28. This constitution prevents the force caused by expansion of a side air bag 18 from being transmitted to the back rear face 14c of the trim cover 14 so as to secure the expansion of the side air bag 18 without any elongation of the back rear face 14c. |
