First Claim
1. A safety belt buckle, comprising:
- a buckle member having a chamber therein and a lateral opening on a side, wherein the lateral opening is communicated with the chamber;
a hook provided in the chamber of the buckle member to be moved between a first position and a second position, wherein the hook stays at the first position under a normal condition, and the hook is moved along a moving trace between the first position and the second position;
a stop member provided in the chamber of the buckle member to be moved between a third position and a fourth position, wherein the stop member stays at the third position under a normal condition, and when the stop member is moved to the fourth position, the stop member is on the moving trace of the hook to stop the hook from being moved to the second position from the first position;
a latch member having a tongue plate to be detachably inserted into the chamber of the buckle member through the lateral opening, wherein when the tongue plate enters the chamber of the buckle member, the tongue plate engages the hook and moves the stop member to the fourth position from the third position to hold the hook at the first position; and

Abstract
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.
