Title:
Air bag device
Document Type and Number:
Japanese Patent JP5915481
Kind Code:
B2
Abstract:
Inside of an airbag is partitioned by a partitioning member into an upstream inflation portion, which is inflated by a supply of gas, and a downstream inflation portion, which is inflated by inflow of the gas from the upstream inflation portion. The partitioning member includes a wide portion where an external force to be applied accompanying an occupant restraint by the airbag becomes largest. In the partitioning member, slits are formed at portions other than the wide portion. The slits cause the gas to flow into the downstream inflation portion from the upstream inflation portion upon the inflation of the airbag. The slits are opened by the force to increase the flow rate of the gas into the downstream inflation portion from the upstream inflation portion during the occupant restraint by the airbag compared to the gas flow rate before the occupant restraint by the airbag.
