Abstract
Abstract A buffering air-bag means adapted to inflate a normally folded air-bag on the occasion of a collision by the generation of gas by a box-like gas generating means having gas ejecting openings formed in a substantially flat end, wherein a gas deflecting plate is provided to traverse the front of the gas ejecting openings in a manner to control the composite reaction force exerted by the gas jets ejected from the gas generating means so that the force properly balances by itself to relieve a steering column from compression.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
178 words
A bufferng air-bag means comprising a gas generating means having a completely hollow outer shell box which is mounted to the hub of a steering wheel, said outer shell box being formed of two substantially U-shaped cup members, the open ends of said cup members engaging with each other so that the open ends thereof close on each other to form a closed, substantially flat bottom wall, a cylindrical perforated sidewall and a perforated, substantially flat top wall, an air bag folded around said outer shell box and adapted to be inflated by gas generated by said gas generating means, and a deflecting plate spaced apart from said top wall of said outer shell box, said deflecting plate having a substantially flat, disc-shaped body which is provided with a plurality of leg portions spaced along the peripheral edge of said disc body, said leg portions being firmly connected to the upper peripheral edge portions of said cylindrical outer shell box so as to hold the substantially flat disc-shaped body relative to said outer shell box in spaced-apart relationship.

Claim 3
Dependent Claim
155 words
A buffering air-bag means comprising a gas generating means having a completely hollow outer shell box which is mounted to a hub of a steering wheel, said outer shell box having a relatively short cylindrical body with a closed, substantially flat bottom wall, a perforated cylindrical sidewall and a perforated, substantially flat top wall, an air bag folded around said outer shell box and adapted to be inflated by gas generated by said gas generating means, and a deflecting plate spaced apart from said top wall of said outer shell box, said deflecting plate having a substantially flat, disc-shaped body which is provided with a plurality of leg portions spaced along the peripheral edge of said disc body, said leg portions being firmly connected to the upper peripheral edge portions of said cylindrical outer shell box so as to hold the substantially flat disc-shaped body relative to said outer shell box in said spaced-apart relationship.
