Problems solved by technology

Since there is only a small gap between the occupant and the door, it may be difficult to inflate the lower end of the airbag into a desired shape if the lower end of the airbag is largely inflated before being deployed toward the side of the occupant's abdomen.

Abstract

The purpose of the present invention is to provide a side airbag device which is configured so that the entire airbag can be promptly and accurately expanded to a correct position and so that the entire airbag can be inflated into a desired shape after the expansion. A side airbag device can be mounted in a seat side section of a vehicle and comprises: a long-shaped inflator (22); and an airbag including an inflatable bag-like section (20) and a partition section (for example, a partition wall section (40)) which divides the bag-like section (20) into a first gas chamber (50) and a second gas chamber (60). The first gas chamber (50) includes: a supporting inflation section (52) which can be expanded into a shape which gradually expands from the lower end to the upper end along the seat side section; and a protective inflation section (54) which can be expanded on the other end side of the supporting inflation section (52). The inflator (22) is disposed so as to be capable of supplying gas into the supporting inflation section (52). At least one gas flow hole (42h) is provided in the portion of the partition section, which separates the second gas chamber (60) and the supporting inflation section (52) of the first gas chamber (50). The second gas chamber (60) is provided below the first gas chamber (50).

Description

technical field [0001] The present invention relates to a side airbag device incorporated in a side portion of a seat of a vehicle. Background technique [0002] Patent Document 1 discloses a side airbag provided on a vehicle outer side portion of a seat back of a vehicle seat. [0003] Inside the side airbag, a first flow path and a second flow path are formed. The first flow path allows the gas ejected from the gas outlet of the inflator to flow to the upper portion of the airbag that protects the occupant's head side, The second flow path allows gas to flow from the upper portion of the airbag to the lower portion of the airbag that protects the chest side of the occupant. The airbag has a structure in which gas is flowed from the inflator into the first flow path during a side collision of the vehicle to inflate and expand the upper portion of the airbag toward the side of the head, and at the same time, gas is flowed into the second airbag from the upper portion of the...
