An occupant protection device for a vehicle, the occupant protection device comprising:
- a right bag body and a left bag body, the right and left bag bodies being accommodated along at least both right and left side portions of a seat back portion of a seat of the vehicle, each of the right and left bag bodies being configured to be deployed between both ends thereof fixed to the seat;
- and
- an inflator configured to deploy the right bag body and the left bag body,
- wherein, while being accommodated along at least both of the right and left side portions of the seat back portion of the seat of the vehicle, each of the right bag body and the left bag body comprises a bent portion between the both ends,
- wherein the right bag body is accommodated in the seat back portion i) in a state where the right bag body is wound with the both ends located outside and the bent portion located inside and ii) in a state where the right bag body is wound clockwise from the both ends to the bent portion when viewed from above,
- wherein the left bag body is accommodated in the seat back portion i) in a state where the left bag body is wound with the both ends located outside and the bent portion located inside when viewed from above and ii) in a state where the left bag body is wound counterclockwise from the both ends to the bent portion when viewed from above, and
- wherein the right bag body and the left bag body are configured to be deployed in such a manner that the right bag body and the left bag body are unwound from a state of being accommodated to reach positions in front of an upper body of an occupant to be seated on the seat.
An occupant protection device for a vehicle, the occupant protection device comprising:
- a right bag body and a left bag body, the right and left bag bodies being accommodated along right and left side portions of a seat of the vehicle, the seat comprising a seat back portion and a seat portion, each of the right and left bag bodies being fixed to an upper portion of the seat back portion at an upper end, each of the right and left bag bodies being fixed to a front portion of the seat portion at a lower end, each of the right and left bag bodies being configured to be deployed between the upper end and the lower end;
- and
- an inflator configured to deploy the right bag body and the left bag body, wherein, while being accommodated along the right and left side portions of the seat, each the right bag body and the left bag body comprises a bent portion between the upper ends and the lower ends,
- wherein a part of the right bag body is accommodated in the seat back portion i) in a state where the right bag body is wound with the upper end located outside and the bent portion located inside and ii) in a state where the right bag body is wound clockwise from the upper end to the bent portion when viewed from above,
- wherein a part of the left bag body is accommodated in the seat back portion i) in a state where the left bag body is wound with the upper end located outside and the bent portion located inside and ii) in a state where the left bag body is wound clockwise from the upper end to the bent portion when viewed from above, and
- wherein the right bag body and the left bag body are configured to be deployed, after the right bag body and the left bag body expand outward from the right and the left sides of the seat from a state of being accommodated, to reach positions in front of an upper body of an occupant to be seated on the seat due to an inertial force generated by unwinding of the wounded parts of the right and the left bag bodies.
