Side air bag device

摘要

A side air bag device for embedding in a compartment wall side of a vehicle seat, wherein seat covering materials (22,24) are stitched so as to be joined together in the vicinity of an air bag case opening (16a), the stitching part (26) being adapted to be split open by means of a predetermined deployment pressure of the air bag (14) and a seat pad (72) of a predetermined thickness is interposed between the air case (16) and the covering materials (22,24). Either a slit part (74) for allowing the air bag (14) to pass through on deployment is formed in the pad on the inner side of the covering material stitching part (26), or a weak part (82) split open by deployment pressure of the air bag (14) to allow the air bag to pass through is formed in the pad on the inner side of the covering stitching part (26).
