Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for fixing a buckle stalk supporting a buckle to a vehicle body in an automobile seat belt.

Conventionally, when fixing a buckle stalk to a vehicle body, a metal sleeve is fitted to the tip of the wire of the buckle stalk, the sleeve is caulked and fixed to the wire, and the tip of the sleeve is further deformed into a flat shape. A hole was drilled in the flat part and it was fixed to the vehicle body with bolts and nuts. However, such a structure does not have sufficient strength,
Another disadvantage is that the length of the part required for fixing becomes long.

In view of the above circumstances, it is an object of the present invention to provide a new mounting structure with high mounting strength and small dimensions of the mounting portion.

Therefore, the present invention has a box-shaped part formed by bending a metal plate into a substantially rectangular shape, and a mounting part in which both ends of the metal plate are extended to the sides of the box-shaped part. ,
A frame having locking holes and support holes drilled in the upper and lower parts of the box-shaped portion, respectively, is fixed to the mounting surface of the vehicle body at the mounting portion, and the wire of the buckle stalk is inserted into the locking hole. A sleeve is fitted onto the tip of the wire and secured by crimping, and the sleeve is positioned within the box-shaped portion, and its tip is fitted into the support hole, and both edges of both sides of the box-shaped portion are caulked to secure the sleeve. It is characterized in that the sleeve is held within a box-shaped part.

1 and 2 show an embodiment of the present invention. In the drawing, 1 is a frame,
It is formed by bending a metal plate, and an extension part 3 and a lower part 4 are formed along the mounting surface 2 of the vehicle body.
The lower part 4 is bent upward from the end to form a side part 5, and the upper end of the side part 5 is further bent to face the lower part 4 to form an upper part 6. It is bent downward again to form a side part 7, and the lower end of the side part 7 is bent so as to overlap with the extension part 3 to form an overlapping part 8, thereby forming an integral frame 1. The lower part 4, the side parts 5, 7, and the upper part 6 form a substantially rectangular box-shaped part 9, and the extension part 3 extends from the lower part 4 of the box-shaped part 9.
The overlapping portion 8 extends laterally to form a mounting portion 10. A locking hole 11 and a support hole 12 are formed in the upper part 6 and lower part of the box-shaped part 9, respectively, and a bolt hole 13 is also formed in the mounting part 10. 14 is a buckle stalk, and a flexible rubber or soft plastic tube 16 is fitted onto a wire 15. At the tip of the buckle stalk 14, a wire 15 is exposed from the tube 16.
passes through a locking hole 11 in the upper part 6 of the frame 1, and a metal sleeve 17 is fitted to the tip thereof and fixed to the wire 15 by caulking. The sleeve 17 is housed in the box-shaped part 9, and its tip is fitted into the support hole 12 in the lower part 4 of the frame 1.

Further, the frame 1 includes both sides 5 and 7 of the box-shaped portion 9.
Both edges are caulked to form a recess 20, which holds the sleeve 17 within the box-shaped portion 9 and holds it in place.

In the present invention, the periphery of the locking hole 11 in the upper part 6 of the box-shaped portion 9 of the frame 1 and the upper end of the sleeve 17 lock with each other to support the tensile force applied to the buckle stalk 14. Therefore, the strength of the attachment part of the buckle stalk is sufficiently large and can support a huge force. Further, the height of the mounting portion is approximately equal to the length of the sleeve 17, and can be made significantly smaller than that of the conventional one. Further, since the sleeve 17 is held within the box-shaped portion 9 of the frame 1 and its tip is fitted into the support hole 12, the buckle stalk 14 is prevented from inadvertently swinging or rattling. There isn't.

In addition, the present invention has a box-shaped part and a mounting part integrally formed by bending a single metal plate, so the structure is extremely simple and strong, ensuring greater safety for the occupants. This is possible.

FIG. 3 shows another embodiment of the present invention, in which when the sleeve 17 is fixed to the wire 15 of the buckle stalk 14, the tip of the wire 15 is made to protrude from the tip of the sleeve 17 to form a protrusion 21. ,
The protrusion 21 is fitted into a through hole 22 formed in the mounting surface 2 of the vehicle body. In the previous embodiment, the frame 1 and the mounting surface 2 of the vehicle body are connected by bolts 18.
And since it is fixed only by nut 19,
There was a possibility that the frame 1 would rotate around the bolt 18 when a large force was applied to the buckle stalk 14, but in this embodiment, the protrusion 21
Since the frame 1 is fitted into the through hole 22, the frame 1 does not rotate.

Furthermore, the sleeve 17 may also be fitted into the through hole 21 as shown in FIG. Since it is possible to increase the contact area, the mounting strength is further increased.

FIG. 5 shows still another embodiment of the present invention,
The frame 1 consists of a lower plate 23 and an upper plate 24, and the lower plate 23 has a central portion forming a lower portion 4 and extension portions 3, 3' on both sides thereof. The center part of the upper plate 24 is bent up into a substantially U-shape to form side plates 5, 7 and an upper part 6, and overlapping parts 8, 8' project laterally from the lower ends of the side plates 5, 7, respectively. The lower part 4, side parts 5, 7 and upper part 6 form a box-shaped part 9, and the extension parts 3, 3' and overlapping parts 8, 8' form attachment parts 10, 10'. The mounting portion 10,
It is fixed to the mounting surface 2 of the vehicle body by bolts 18, 18' and nuts 19, 19' in bolt holes 13, 13' drilled in 10'.

In this embodiment, the box-shaped part 9 is fixed on both sides with bolts 18, 18' and nuts 19, 19', so that the mounting strength is greater, and the frame 1 can be rotated around the bolts. Never happened.

Further, in this embodiment, the lower plate 23 can be omitted as shown in the modification shown in FIG. That is, the side parts 5 and 7 of the upper plate 24, the upper part 6, and the mounting surface 2 of the vehicle body form a box-shaped portion 9, and a support hole 12 is bored in the mounting surface 2 of the vehicle body, into which the sleeve 17 is inserted.
The tips of the two are fitted.

What is shown in FIG.
A mounting portion 10 extends laterally from the top, and the box-shaped portion 9 is fitted into a hole 25 drilled in the mounting surface 2 of the vehicle body, with only the upper portion 6 and the mounting portion 10 extending from the mounting surface 2 of the vehicle body. is exposed and fixed with bolts 18 and nuts 19. FIG. 8 shows a modification of the lower plate 23, in which the central portion of the lower plate 23 is bent into a substantially U-shape to form side portions 5, 7 and a lower portion 4, and the upper ends of both side portions 5, 7 are bent toward the sides. extending to form extension parts 3, 3',
Superimposed thereon is a flat top plate 24, which forms the upper part 6 and the overlapping parts 8, 8'. The upper part 6, side parts 5, 7, and lower part 4 form a box-shaped part 9, and the box-shaped part 9 is fitted into a hole 25 formed in the mounting surface 2 of the vehicle body.

In this embodiment, most of the frame 1 and the sleeve 17 are buried under the mounting surface 2 of the vehicle body, so the height of the mounting portion exposed on the mounting surface 2 is extremely low. There is an advantage.

In the present invention, when the sleeve 17 is caulked, it is preferable to caulk it into a prismatic shape (hexagonal column in the drawing) as shown in FIG. . Thereby, when the sleeve 17 is fitted into the support hole 12, the buckle stalk 4 is prevented from rotating relative to the frame 1, and the posture of the buckle can be maintained correctly.

In addition, in the embodiment, the locking hole 11 is simply a hole bored in the upper part of the box-shaped portion 9, but if the strength of the locking hole 11 is not sufficient with this configuration, the locking hole 11 may be The locking hole 11 can be reinforced by squeezing the periphery downward into a cylindrical shape and supporting the sleeve 17 with the cylindrical portion.
