Abstract

A safety belt buckle includes a base and a latch. The base includes a chamber with at least one positioning member disposed therein, and an opening communicating with the chamber. The latch includes a tongue with at least one recess with one open side, is adapted to be inserted into the chamber through the opening. The at least one positioning member is introduced into the at least one recess through the open side thereof to be engaged with the at least one recess when the tongue is inserted into the chamber. By the design mentioned above, the latch could be engaged with the positioning member of the base through the recess. Whereby, the latch still could be engaged with the base securely and would not be released easily and accidentally when any one of the latch and the base is laterally pushed or pulled.

Claims

1. A safety belt buckle, comprising:

a base, including a chamber and an opening, wherein the chamber is disposed with at least one positioning member therein, and the opening communicates with the chamber; and

a latch, including a tongue with at least one recess and adapted to be inserted into the chamber through the opening, wherein the at least one recess has an open side;

the at least one positioning member is introduced into the at least one recess through the open side to be engaged with the at least one recess;

wherein when the tongue is located in the chamber and an exterior force is exerted from a lateral direction with respect to an inserting direction of the latch, the latch tilts with respect to the base so far as the at least one positioning member abuts against a lateral surface of the at least one recess;

wherein the at least one positioning member integrally protrudes from an inner surface of the chamber of the base;

wherein the tongue has two opposite surfaces, each of which includes one recess respectively;

the open sides of the two recesses are positioned toward the same direction;

wherein inside of the chamber is disposed with two positioning members which are located respectively on two opposite sites in the chamber;

the two positioning members are respectively introduced into and engaged with the two recesses when the tongue is inserted into the chamber.

2. The safety belt buckle of claim 1, wherein a top portion of the at least one positioning member is adapted to abut against a bottom surface of the at least one recess.

3. The safety belt buckle of claim 2, wherein a side portion of the at least one positioning member is adapted to abut against a sidewall surface of the at least one recess.

4. The safety belt buckle of claim 3, wherein the side portion has a convex curved surface which is adapted to abut against the sidewall surface of the at least one recess.

5. The safety belt buckle of claim 1, wherein a side portion of the at least one positioning member is adapted to abut against a sidewall surface of the at least one recess.

6. The safety belt buckle of claim 5, wherein the side portion has a convex curved surface which is adapted to abut against the sidewall surface of the at least one recess.

7. The safety belt buckle of claim 1, wherein the at least one positioning member is formed by stamping the base.

8. The safety belt buckle of claim 1, wherein the base includes an aperture which communicates with the chamber;

the tongue of the latch includes a labelling part which could be exposed by the aperture when the tongue is inserted into the chamber.

9. The safety belt buckle of claim 1, wherein the safety belt buckle further comprises a position limiting member located in the chamber of the base, which could be moved between a first position and a second position, and a stopper disposed inside of the chamber of the base;

when the position limiting member is at the first position, an edge portion of the position limiting member abuts against the latch so as to restrict the latch from being detached from the base;

when the position limiting member is at the second position, the edge portion of the position limiting member is apart from the latch so that the latch could be detached from the base.

10. The safety belt buckle of claim 9, wherein the stopper is formed by stamping the base.

11. A safety belt buckle, comprising:

a base, including a chamber and an opening, wherein the chamber is disposed with at least one positioning member therein, and the opening communicates with the chamber; and

a latch, including a tongue with at least one recess and adapted to be inserted into the chamber through the opening, wherein the at least one recess has an open side;

the at least one positioning member is introduced into the at least one recess through the open side to be engaged with the at least one recess;

wherein when the tongue is located in the chamber and an exterior force is exerted from a lateral direction with respect to an inserting direction of the latch, the latch tilts with respect to the base so far as the at least one positioning member abuts against a lateral surface of the at least one recess;

wherein the at least one positioning member integrally protrudes from an inner surface of the chamber of the base;

wherein the at least one positioning member includes two positioning posts which are respectively adapted to abut against two sidewall surfaces of the at least one recess via two side portions thereof.

12. A safety belt buckle, comprising:

a base, including a chamber and an opening, wherein the chamber is disposed with at least one positioning member therein, and the opening communicates with the chamber; and

a latch, including a tongue with at least one recess and adapted to be inserted into the chamber through the opening, wherein the at least one recess has an open side;

the at least one positioning member is introduced into the at least one recess through the open side to be engaged with the at least one recess;

wherein when the tongue is located in the chamber and an exterior force is exerted from a lateral direction with respect to an inserting direction of the latch, the latch tilts with respect to the base so far as the at least one positioning member abuts against a lateral surface of the at least one recess;

wherein an end of the at least one positioning member integrally protrudes from an inner surface of the chamber of the base, and another end of the at least one positioning member is a free end which does not contact with the inner surface of the chamber of the base;

wherein the tongue has two opposite surfaces facing opposite directions;

at least one of the two opposite surfaces of the tongue has the at least one recess which does not penetrate through the two opposite surfaces of the tongue.
