Abstract

Abstract A buckle for safety seat belts in vehicles comprises a locking tongue and a locking housing. The housing has a spring-loaded operating arm with a locking member which is arranged to engage the locking tongue in the position thereof when inserted in the locking housing. Further, the locking housing has a spring-loaded cam which tends to push the locking tongue out of the housing from the position therein. The cam coacts with a latch which blocks the operating arm in the open position of the buckle. The cam, however, is adapted to release the latch when the locking tongue occupies its position in the locking housing.
