Rivets form the pivot of the seat belt buckle.

Abstract

A seatbelt buckle with a rivet pivot includes a buckle base, which is a flat housing comprising a first half-shell and a second half-shell. Along the insertion direction, it sequentially forms an insertion port, a chamber, and a belt threading hole. The first half-shell has two first pivot holes, and the second half-shell has two second pivot holes corresponding to the two first pivot holes. Two pivot rivets are inserted into the corresponding first and second pivot holes. Each pivot rivet has a shaft, and the shafts of the two pivot rivets are located on both sides of the chamber. Two limit buttons are accommodated on both sides of the chamber. Each limit button has a pivot portion and a buckle arm, and is rotatably fitted onto the corresponding shaft through the pivot hole of the pivot portion. Two return springs are provided on both sides of the chamber to provide a return force to the buckle arm. Thus, the shaft forms a pivot for the rotation of the limit buttons, improving the smoothness and stability of the limit button rotation.

Claims

1. A seatbelt buckle with a rivet forming a pivot, comprising: A fastener, a flat box-shaped housing comprising a first half-shell and a second half-shell, defines an insertion direction, and sequentially forms a socket, a chamber, and a strap hole along the insertion direction. The first half-shell has two first shaft holes, and the second half-shell has two second shaft holes corresponding to the two first shaft holes. Two pivot rivets, each pivot rivet passing through a corresponding first shaft hole and a corresponding second shaft hole, and each pivot rivet comprising a head, a shaft, and a riveting rod connected in sequence, each head abutting against the outer periphery of the corresponding first shaft hole, each shaft passing through the chamber on a corresponding side in a direction perpendicular to the insertion direction, and each riveting rod exiting the corresponding second shaft hole and forming a riveting portion at its outer end, each riveting portion abutting against the outer periphery of the corresponding second shaft hole. Two limiting buttons are housed in the chamber on both sides perpendicular to the insertion direction. Each limiting button has a pivot portion, and each pivot portion forms a pivot hole. Each pivot hole is rotatably fitted onto a corresponding shaft, so that each shaft constitutes a pivot for the corresponding limiting button to rotate relative to the buckle. A lever and a buckle arm are connected to each pivot portion. Each lever extends out of the insertion port, and each buckle arm extends from the corresponding pivot portion in a direction away from the insertion port. Two return springs are respectively disposed on both sides of the chamber in a direction perpendicular to the insertion direction, and each return spring is disposed between the buckle and the corresponding buckle arm, providing a return force to the corresponding buckle arm.

2. The rivets as described in claim 1 constitute a pivotal seatbelt buckle, wherein the second half-shell is connected to a ring at the inner periphery of each of the second shaft holes, and each ring protrudes toward the chamber; the outer diameter of the shaft of each pivot rivet is the same as the outer diameter of the corresponding ring, and the outer diameter of the riveting rod of each pivot rivet is smaller than the outer diameter of the corresponding shaft, such that each pivot rivet forms an annular shoulder between the shaft and the riveting rod, each annular shoulder abuts against the end of the corresponding ring facing the shaft, and the outer peripheral surface of each shaft is flush with the outer peripheral surface of the corresponding ring; each pivot hole is rotatably fitted onto the corresponding shaft and the corresponding ring.

3. The seat belt buckle constituting a pivot as described in claim 1, wherein the seat belt buckle further includes a sliding pressure bar, the sliding pressure bar being movably disposed in the buckle in the insertion direction, and including a bar body and two end bars respectively connected to both ends of the bar body, the bar body being at least partially located in the belt hole, and the two end bars respectively extending into the buckle.

4. The rivet as described in claim 3 constitutes a pivot seat belt buckle, wherein the buckle has a connecting portion on each side of the strap hole in a direction perpendicular to the insertion direction, the two connecting portions respectively connecting the strap hole and the interior of the buckle, and the two end rods respectively extend into the buckle through the two connecting portions.

5. A seatbelt buckle with a pivot as described in claim 3, wherein the first half-shell forms a first opening, the second half-shell forms a second opening, and the first opening and the second opening together form the belt hole; the rod body forms a first protrusion and a second protrusion on its sides facing the first opening and the second opening, respectively, the first protrusion extending into the first opening and the second protrusion extending into the second opening.

6. A seatbelt buckle constituting a pivot as described in claim 3, wherein the first half-shell has a first inner wall and two first side walls, the two first side walls being respectively connected to the two side edges of the first inner wall in a direction perpendicular to the insertion direction; the first half-shell forms a stop block on the side of the buckle facing away from the insertion port, the stop block being connected between the two first side walls and forming a stop surface facing the insertion port; the first half-shell has two first riveting holes, the two first riveting holes respectively passing through the stop block; the second half-shell has two second riveting holes respectively corresponding to the two first riveting holes; two buckle rivets are provided in conjunction with the two first riveting holes, each buckle rivet passing through the corresponding first riveting hole and the corresponding second riveting hole, so as to rivet the first half-shell and the second half-shell together.

7. A seatbelt buckle constituting a pivot as described in claim 6, wherein the second half-shell has a second inner wall disposed opposite to the first inner wall, and the chamber is formed between the first inner wall and the second inner wall and located between the two first side walls.

8. The rivet constituting the pivot seat belt buckle as described in claim 7, wherein the first half-shell forms a first central stop block in the middle region of the first inner wall adjacent to the belt hole, the first central stop block protruding toward the chamber; and the second half-shell forms a second central stop block in the middle region of the second inner wall adjacent to the belt hole, the second central stop block protruding toward the chamber.

9. A seatbelt buckle with a pivot as described in claim 8, wherein the first half-shell forms two ribs on the first inner wall adjacent to the belt insertion hole on both sides, the two ribs protruding toward the chamber, and the first central stop block is located between the two ribs, the two ribs being located on the side of the sliding pressure bar facing the insertion port; the stop surface is located on the side of the sliding pressure bar away from the insertion port, so that the two ribs and the stop surface limit the range of movement of the sliding pressure bar along the insertion direction.
