ABSTRACT:
The housing of a seat belt buckle is comprised of C-shaped one-piece stamping having upper and lower legs which are spaced apart to receive the apertured latch plate therebetween. A detent is formed integral with the lower leg and projects upwardly into the path of entry of the apertured latch plate so that the latch plate interacts with the detent to forcibly cam the lower leg downwardly away from the upper leg as permitted by integral elastic yielding of the lower leg relative to the upper leg. The push button is mounted for movement relative to the upper leg and engages the lower leg so that depressing the push button forces the lower leg downwardly to remove the detent from the engagement with the aperture latch plate. The housing is preferably enclosed in a plastic cover which has an entry port aligning the aperture plate for insertion between the upper and lower legs. The upper leg may have a downturned integral tab extending from the end thereof into closely spaced proximity with the end of the lower leg so that upon a forced removal of the apertured latch plate carries the lower leg is carried into engagement with the downturned integral tab to restrain further yielding of the lower leg by the occupant restraining force.
