  • Patent number: 9969348
    Abstract: Influence from a rear bag section is prevented or suppressed from being applied to an occupant out of position. In a state in which a side airbag inflates and deploys frontward of a side support section of a seat back, a front-rear partition cloth that partitions a bag body into a front bag section and a rear bag section brings an intermediate portion in a vehicle width direction of a front surface of the rear bag section to be recessed toward a vehicle rearward direction so as to be a valley-shaped recessed portion. Through this, even if the side airbag inflates and deploys while the occupant is located frontward of the side support section, it is possible to prevent or suppress influence from the rear bag section to this occupant.

  • Patent number: 9849857
    Abstract: In the side airbag device, in an inflation and deployment state of the side airbag, a tension cloth extendingly disposed across between a front-rear partition and a rear end of the rear bag section is stretched, thereby restricting inflation in the vehicle front-rear direction of the rear bag section. An inflating width in a vehicle width direction of the rear bag section can be increased without significantly changing a position in the vehicle front-rear direction of the front-rear partition. In a flat developed state of the side airbag, the tension cloth is extendingly disposed across between the front-rear partition so folded into two as to protrude toward the rear bag section, and the rear end of the rear bag section. Accordingly, dimensions of each component can be so defined as to cause no redundancy in the rear bag section in the flat developed state, thus compactly folding the side airbag.
