Abstract

Disclosed is a buckle apparatus for a seat belt. The buckle apparatus Includes an upper cover including a front plate formed with an opening part; a lower cover engaged with a lower portion of the upper cover and provided therein with a base frame; a latch member including one end rotatably supported on the base frame and locked with a tongue plate inserted through the opening part; an ejector assembly provided on the base frame for locking and releasing between the tongue plate and the latch member; and a release button slidably provided on both sides of the base frame and disposed in an upper portion of the opening part so that one side of the release button is exposed. At least one elastic member is integrally provided on an upper end of the front plate to elastically press a bottom surface of the tongue plate.

First claim

The invention claimed is:

1. A buckle apparatus for a seat belt, the buckle apparatus comprising:
an upper cover including a front plate formed with an opening part;
a lower cover engaged with a lower portion of the upper cover and provided therein with a base frame;
a latch member including one end rotatably supported on the base frame and locked with a tongue plate inserted through the opening part;
an ejector assembly provided on the base frame for locking and releasing between the tongue plate and the latch member; and
a release button slidably provided on both sides of the base frame and disposed in an upper portion of the opening part so that one side of the release button is exposed,
wherein at least one elastic member is integrally provided on an upper end of the front plate to elastically press a bottom surface of the tongue plate.

2. The buckle apparatus of claim 1 , wherein the elastic member comprises:
a support part protruding from the upper end of the front plate toward an inner side of the upper cover, and the support part being movable up and down; and
a pressing protrusion protruding from a free end of the support part and coming into contact with the bottom surface of the tongue plate.

3. The buckle apparatus of claim 2 , wherein the pressing protrusion comprises:
a contact surface coming into contact with the bottom surface of the tongue plate; and
an inclined surface inclined downward from the contact surface toward a proximal end of the support part.

4. The buckle apparatus of claim 2 , wherein the front plate is inclined toward the opening part to guide an insertion operation of the tongue plate.

5. The buckle apparatus of claim 1 , wherein the opening part is defined by transverse walls protruding from inner surfaces of both side walls of the upper cover; and longitudinal walls extending downward from each distal end of the transverse walls by a predetermined distance, and
the elastic member protrudes from the upper end of the front plate located between the longitudinal walls.
