Air bag system
First Claim
1. An air bag system, comprising:
- a primary air bag and a secondary air bag, said primary air bag being inflatable and deployable by a high-pressure gas; and
said secondary air bag being disposed on a side of the primary air bag facing an occupant, said secondary air bag being inflatable and deployable by the high-pressure gas which is introduced into the secondary air bag through said primary air bag, each of said primary air bag and said secondary air bag having at least one vent hole through which the high-pressure gas used to inflate and deploy the primary air bag and the secondary air bag is exhausted, an amount of the high-pressure gas exhausted from said at least one vent hole in the secondary air bag being larger than another amount of the high-pressure gas exhausted from said at least one vent hole in the primary air bag.

Abstract
Provided is a safer air bag system which relieves shock to the head and face of an occupant when an air bag inflates and deploys. An air bag body 1 consists of a primary air bag 2 and a secondary air bag 3 which is provided on the front surface of the primary air bag 2. When an inflator 4 is actuated, the high-pressure gas is introduced into the primary air bag 2 to inflate and deploy the primary air bag 2 and then fed into the secondary air bag 3 through gas introducing ports 6 of the primary air bag 2 so that the secondary air bag 3 inflates and deploys more slowly than the primary air bag 2. The secondary air bag 3 thus absorbs shock to the face of the occupant caused by the inflation and deployment of the primary air bag 2.
