Buckle for restraint belts, particularly for car safety seats for children

摘要

A buckle includes a snap coupling mechanism including a locking element pivotable between a locked and an unlocked position for engaging and disengaging two tongues, respectively; a release button movable between a raised position and a lowered position corresponding to the locked and unlocked positions, respectively; a spring tending to keep the release button in the raised position; and two sliders opposing the insertion of the tongues. The sliders are configured to come between a body of the buckle and the locking element, when the locking element is moved into the unlocked position, so as to prevent the locking element from moving from the unlocked position to the locked position. The release button is connected to the locking element so that when the release button is pressed, the locking element moves into the unlocked position, whereas when the release button is released, the locking element moves into the locked position.
