Abstract
Abstract Belt-lock and plug-in tongue for safety belt having movable spring loaded latch and slideable member to move latch out of engagement by pressing push button. A wire spring is disposed in the push button with a bent portion of the spring banked at the lock housing to effect counter-action for the pressure against the push button and a free, bent-spring ending abutting against the slide member to keep it fixed and prevent rattling. The spring arrangement also relieves pressure on the sliding member when the push button is pressed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
147 words
Belt-lock and plug-in tongue for a safety belt comprising a lock-housing having a plug-in opening for insertion of a plug-in tongue, a movable spring-loaded latch disposed in said opening in the path of said plug-in tongue effecting locking of the inserted tongue, a slide member slideable in a guide in the lock-housing to move said latch out of engagement with said tongue to permit separation of the tongue from the belt-lock, a push-button mounted on the housing over the slide-member with pressure on the push-button activating the slide-member to slide and move the latch out of engagement with the tongue, a spring made of spring-wire disposed in the push-button with a bent portion of the spring banked at the lock-housing to effect an elastic, springy counter-action against pressure for the push button, and with the spring having a free, bent-spring ending abutting elastically against the slide member.

Belt-lock according to claim 1, wherein the spring is essentially U-shaped with the bent portion in form of a spring loop, wherein a portion of the wire which precedes the spring ending is constrained in the push button, and wherein the spring ending which abuts against the slide-member rotates together with the rotation of the spring loop and the torsion of the wire which is constrained which precedes the spring ending.
Claim 4
Dependent Claim
38 words
Belt-lock according to claim 2, wherein at the bottom side of the push button are lateral hollow spaces in which said constrained wire, and also a bent support end extending from the spring portion are supported and secured.
