Seat structure having a side impact air bag apparatus

摘要

A seat structure having a side impact air bag apparatus, constructed such that the air bag apparatus, which is integrated into a side portion of a seat back which side portion opposes a vehicle door, is activated at the time of a side impact such that a sewn portion of a seat surface layer, which is formed by sewing a front seat surface layer for covering the front of the seat back to a side seat surface layer for covering the side of the seat back, breaks and an air bag body inflates between a side portion of a vehicle body and the side of a vehicle occupant, comprising a sheet member provided inside the side seat surface layer integrally with the side seat surface layer, the sheet member being harder to stretch than the side seat surface layer, and one end of the sheet member being sewn to the sewn portion; and a fixing member provided inside the seat back, the fixing member being engaged with another end of the sheet member which is provided on the opposite side of the one end of the sheet member.
