Head protecting airbag system
First Claim
1. A head protecting airbag system comprising:
- an inflator located in a predetermined position on a vehicle, that is activated upon at least one of a side collision and a rollover of the vehicle;
an airbag including a gas supply path connected to the inflator, and an inflation section connected to the gas supply path to protect a head of an occupant, wherein the airbag is folded up in a vehicle height direction and stored along a roof side rail section of the vehicle, and is deployed by gas from the inflator downward along a side of a vehicle body in a passenger compartment;
a pillar garnish provided on a side of the vehicle body in the passenger compartment; and
an airbag guide mechanism, provided at a location above the pillar garnish, that guides the deployment of the airbag toward the passenger compartment, wherein;
the gas supply path includes a pillar covering part provided at a location corresponding to an upper part of the pillar garnish and a window covering part provided at a location corresponding to an upper part of a side window of the vehicle; and
when the airbag is deployed, the pillar covering part protrudes further into the passenger compartment than the window covering part.

Abstract
A supplemental inflation part is formed in a portion of an upper-end side inflation section of an airbag, the portion overlapping a B-pillar garnish. The supplemental inflation part has a semicircular shape that forms a push-out part. Folding the push-out part allows the upper-end side inflation section to be inflated largely at the initial stage of deployment of the airbag. Thus, the airbag is pushed toward the passenger compartment with greater force upon its deployment. Therefore, a terminal part of a headliner that covers the folded airbag is largely opened so that the airbag deploys smoothly downward along the side of the vehicle body in the passenger compartment without interference from the top end of the B-pillar garnish.
