US 6,012,659 A · Method for discriminating between used and unused gas generators for air bags during car scrapping process

Abstract

To provide a method for easily discriminating used and unused gas generators from among gas generators for air bags separated from used cars in a car scrapping process. A method for discriminating between used and unused gas generators according to the present invention is a method for discriminating used and unused gas generators from among gas generators for air bags separated from used cars in a car scrapping process, and this method comprises the steps of: a) crushing used cars mounted with gas generators each having on a surface thereof a material discoloring according to the surface temperatures in actuating the gas generator to separate the gas generators, and b) discriminating the gas generators in which surfaces are discolored and the gas generators in which surfaces are not discolored from among the separated gas generators.

A method for discriminating between used and unused gas generators in a process for scrapping cars mounted with gas generators each having on a surface thereof, a material that discolors according to the surface temperatures in actuating the gas generators, comprising:

a) crushing the used cars to separate used or unused gas generators for air bags from the cars;
and
b) discriminating the gas generators, in which surfaces are discolored, and the gas generators, in which surfaces are not discolored, from among the separated gas generators.

Dependencies are inferred from the claim text.
