PROBLEM TO BE SOLVED: To make developing directivity of an airbag constant with stability by forming sewing seams to a breaking part of a trim cover by sewing one terminal of stay cloth together with terminals of a front surface cover part and a side surface cover part and sticking and fixing the other terminal together with each terminal of the front surface cover part and the side surface cover part. SOLUTION: A trim cover 2 is provided at the inside of a front surface cover part 2a and a side surface cover part 2b from sewing seams 2c in which stay cloth 7, 8 form a breaking part 3. In the stay cloth 7, 8, sewing seams 2c to be the breaking part 3 of the trim cover 2 are formed by sewing the trim cover 2 into a bag-shape and by sewing one terminal together with each terminal of the front surface cover part 2a and the side surface cover part 2b. By pulling and sticking the other terminal to a cushion spring 10 by a hanging wire 9 in the front surface cover part 2a and sticking the other terminal to a retainer 4b of a seat back frame 4 by a wire in the side surface cover part 2b, the other terminal is strongly connected and fixed to stand expanding pressure of an airbag. |
