Side air bag device
First Claim
1. A side air bag device which is an air bag device embedded in a compartment wall side of a seat of a vehicle wherein a seat covering material has in the vicinity of an air bag case opening a stitching part where a case side covering material covering the opening and an occupant side covering material are stitched together by said stitching part and this stitching part is to be split open by means of a predetermined deployment pressure of an air bag,said side air bag device characterized in that a seat pad of a predetermined thickness is interposed between the air bag case and the seat covering material and a slit part or a weak part for allowing the air bag to pass through on deployment is formed in the pad on the inner side of the stitching part,and also a band for suppressing elongation of the occupant side covering material on deployment of the air bag is provided extending between the occupant side covering material at the stitching part and a fixed member such as a seat frame, one end of the band is fixed to the fixed member and the other end of the band is co-stitched to the occupant side covering material by means of stitching thread of the stitching part.

Abstract
The invention relates to a side air bag device embedded in a seat side which splits open a stitching part 26 of a seat covering material 20 by means of deployment pressure of an air bag 14 and deploys the air bag 14. In this device, a band 28 for concentrating deployment pressure of the air bag 14 on deployment of the air bag 14 is disposed, and a start to the stitching part 26 splitting open is made by means of this band 28. As a result, the stitching part 26 can be split open rapidly. Also, in the device, a seat pad 72 was interposed between an air bag case 16 and the seat covering material 20. As a result, the softness and feeling of the seat feel is not lost.
