Abstract
A buckle for vehicle safety belt systems equipped with a belt pretensioner engaging on the buckle is provided. The buckle has a release button with a cutout wherein a pushbutton is slidably received. The release button carries a two-armed blocking lever pivotally mounted thereon. In normal use, the blocking lever, when the pushbutton is depressed, is pivoted away from a stop member on the buckle housing to permit the release button to be moved until the buckle opens. When after activation of the belt pretensioner the buckle has reached the end of its stroke the release button tends to continue its movement, but the two-armed lever will hit on the stop member to prevent the release button from moving towards its release position.
