Abstract
An occupant protection device comprises a pair of bag bodies, that is provided in left and right side support sections in a seat width direction of a seatback of a vehicle, and that displace the side support sections by inflating when supplied with gas; a first gas supply mechanism that supplies gas to the pair of bag bodies during everyday use; and a second gas supply mechanism that supplies gas to at least one out of the pair of bag bodies and that inflates the bag body earlier than in cases in which the pair of bag bodies are inflated by gas supplied by the first gas supply mechanism, in the event that a collision has been predicted or detected.
Claims8
An occupant protection device comprising:
- a pair of bag bodies, that are provided in left and right side support sections in a seat width direction of a seatback of a vehicle, and that displace the side support sections by inflating when supplied with gas, the pair of bag bodies including:
- an outer side bag body provided in an outer side support section that is disposed on a window side of a vehicle;
- and
- an inner side bag body provided in an inner side support section that is disposed on an opposite side to the outer side support section;
- a first gas supply mechanism that supplies gas to the pair of bag bodies during everyday use, the first gas supply mechanism including:
- a pump provided in the inner side support section;
- an outer side bag body first connection member that is connected to the pump and the outer side bag body, and that supplies gas from the pump to the outer side bag body;
- and
- an inner side bag body first connection member that is connected to the pump and the inner side bag body, and that supplies gas from the pump to the inner side bag body;
- and
- a second gas supply mechanism that supplies gas to at least the outer side bag body and that inflates at least one of the bag bodies more quickly than in cases in which the pair of bag bodies are inflated by gas supplied by the first gas supply mechanism, in the event that a collision has been predicted or detected, the second gas supply mechanism including a reserve tank that:
- is connected to the outer side bag body;
- contains high pressure gas at a higher pressure than a pressure in the at least one bag body;
- and
- is capable of supplying the high pressure gas to the at least one bag body.
