Abstract
The invention relates to a buckle for a safety belt for vehicles comprising a tongue-shaped insertion part (1) and a sleeve-shaped receiving part (2), a primary lock (10) being provided in the receiving part, which lock is pivoted on a shaft (9), which is parallel to the plane of the insertion part and perpendicularly arranged relative to the direction of insertion of said insertion part, the primary lock exhibiting one or several projections, which cooperate with corresponding stop dogs (11) on the insertion part. According to the invention the primary lock comprises a double armed lever, of which the end located nearest to the insertion opening of the receiving part, i.e. one of its arms exhibits said stop dog (11) cooperating with the insertion part (1) and of which lever the arm extending in opposite direction cooperates with a secondary lock (18), which tends to maintain the primary lock in its engaging position, the secondary lock against the bias of a spring being displaceable substantially in the longitudinal direction of the arm belonging to the primary lock into a position, in which the arm can freely pivot towards the neutral position of the primary lock.
