Air bag for steering wheel

摘要

An air bag mounted in an automotive steering wheel and having a bag body and flow regulation fabric mounted within the bag body. The bag body includes a front panel and a rear panel and is a horizontally symmetrical, planar bag body. The front panel is provided with a gas inlet port. The flow regulation fabric branches from the gas inlet port into radially extending right and left passages that run to the outer fringes of the bag body. Circumferentially extending passages of the flow regulation fabric extend from the front ends of the radially extending passages along the fringes of the bag body vertically, and are each provided with upper and lower opening ends at which gas can be ejected toward the vertical centerline of the bag body. Upon expansion, the air bag quickly enters between the occupant's abdomen and the rim of the steering wheel.
