Abstract: A vehicle occupant re-straining device, comprising, an air bag inflated and deployed on both sides of a vehicle occupant; tension cloth housed so as to extend from the inside of the seat back of a seat into a seat cushion; an angle detection means for detecting the reclining angle of the seat back; and an inner pressure control means for controlling, depending on the reclining angle, pressure in the air bag at the time of inflation and deployment thereof, wherein the tension cloth is deployed on the sides of the seat when the surface material of the seat is broken open by the inflation and deployment of the air bag, thereby holding the surfaces of the air bag, which are located on the opposite sides of the vehicle occupant, and wherein the inner pressure control means reduces pressure in the air bag.

Abstract: [Problem] To provide a passenger restraint apparatus capable of suppressing the movement of an airbag away from a passenger without requiring a complex structure. [Resolution Means] A passenger restraint apparatus according to the present invention is configured to include a seat of a vehicle and restrain a passenger seated in this seat, wherein this passenger restraint apparatus includes: an airbag which is stored in a seat back part of the seat, and expanded and deployed to the side of the passenger seated in this seat; and a tension fabric which passes through the side opposite the passenger of the stored airbag so as to be stored from the seat back part of the seat to the seat cushion part, wherein, when the airbag is expanded and deployed, at least a portion of the tension fabric is configured so as to be deployed to the outside of this seat by the cleaving of the skin of the seat, in addition to being stretched from the position in the vicinity of the shoulder of the passenger in the seat back to the position on the front side of the vehicle on the side of the seat cushion, and wherein this tension fabric includes a part for holding the surface of the airbag opposite the passenger.

Abstract: An occupant restraint device including: right and left airbags stored inside right and left sides of a seat back of a vehicle seat, respectively; right and left tension cloths connected to outer surfaces of the right and left airbags, respectively; and a lower tension cloth disposed inside a seat cushion of a vehicle seat, the lower tension cloth being continuously connected between lower parts of the right and left tension cloths. The lower tension cloth is movable in right and left directions with respect to an occupant sitting in the vehicle seat. When the right and left airbags are expanded and deployed, the right tension cloth, the left tension cloth, and the lower tension cloth are configured to push the expanded and deployed right and left airbags toward the occupant.
