Patent attributes
A safety belt buckle, which includes a buckle member, a hook, a stop member, a latch member and a release button, wherein the latch member has a tongue plate which enters a chamber of the buckle member through a lateral opening of the buckle member, and pushes the stop member to a predetermined position; when the stop member stays at the predetermined position, the hook is restricted by the stop member, and stopped at another predetermined position to engage the tongue plate, which makes the latch member unable to separate from the buckle member. By pushing the release button connected to the stop member, the hook can pivot unrestrictedly, therefore the tongue plate is no longer engaged by the hook, and the latch member and the buckle member can separate from each other.
