Claim 0:
1. A passenger restraining device for restraining a passenger sitting on a seat of a vehicle, comprising:
an airbag at least partially stored in a seat back portion of the seat and expandable and deployable to a side of the passenger sitting on the seat; and
a plurality of tension cloths each extending from a seat back attachment point at a top of the seat back portion to a seat cushion attachment point; wherein:
the plurality of tension cloths is deployable to an outside of the seat by expanding and deploying the airbag and stretchable from an upper surface of the seat back portion to a seat cushion portion,
wherein the airbag when viewed in plan view from above during expansion and deployment, includes four regions demarcated by a first imaginary line extending in a front-rear direction of a vehicle through a center of a widest portion of the airbag on a straight line perpendicular to a left-right direction of the airbag and a second imaginary line orthogonal to the first imaginary line and extending in the left-right direction through a center of the first imaginary line in the left-right direction of the airbag, the four regions including a first region on a rear side of the second imaginary line and on a first side of the first imaginary line, the first side of the first imaginary line configured to be closer to the passenger, a second region on a front side of the second imaginary line and on the first side of the first imaginary line, a third region on the front side of the second imaginary line and on a second side of the first imaginary line, the second side opposite to the first side, and a fourth region on the rear side of the second imaginary line and on the second side of the first imaginary line,
wherein the plurality of tension cloths diagonally extends over the airbag and passes through at least the first region to the third region upon deployment of the airbag,
wherein the plurality of tension cloths has a collective width that increases from the first region to the third region upon deployment of the airbag,
wherein the plurality of tension cloths extends over and contacts an upper surface of the airbag upon deployment of the airbag, and
wherein the collective width of the plurality of tension cloths, upon deployment, has a maximum width at an area contacting the airbag; and
wherein an attachment point width at both of a point of the seat back attachment point and the seat cushion attachment point is less than the maximum width.
