Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a spring connection clip for an automobile seat.

(Prior Art) Conventionally, as shown in FIGS. 14 and 15, frames 1,
Clips 5 are used to connect adjacent S-shaped spring wires 3, 3 attached to 2 directly or indirectly via wires 4. As shown in FIGS. 12 and 13, this clip 5 is designed to be wound and fastened around, for example, two spring wires 3, 3.

(Problem to be solved by the invention) However, in the clip 5, the two spring wires 3, 3 made of a hard material such as spring steel are in direct contact with each other, so they rub against each other and produce abnormal noise. There was a problem.

Furthermore, even when the clip 5 is tightly tightened, the spring wires 3, which are the members to be tightened, are curved and have a circular cross section, so there is a problem that they tend to loosen.

Furthermore, when tightening the clip 5, the spring wires 3, 3 must be brought together to meet each other, otherwise the clip 5 cannot be tightened, resulting in poor workability.

The present invention was devised in view of the above problems, and an object of the present invention is to provide a spring connection clip for an automobile seat that does not generate abnormal noise.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a spring connection clip for an automobile seat that is wound around two spring wires and fastened. A tongue piece is provided in between.

(Operation) When the tongue piece at one end of the clip is inserted between the two spring wires and then wrapped and tightened, the two spring wires are separated via the tongue piece, so they do not touch each other and rub. No sound will be generated.

Also, since the two spring wires are tightened from both sides by the tongue and base of the clip,
It is tightly bound without loosening.

(Example) Next, an example of the present invention will be described according to the drawings.

The clip 6 shown in FIG. 1 has a convex tongue 7 formed at one end, and a recess 8 into which the tongue 7 can be engaged at the other end. As shown in FIG. 2, this clip 6 is fastened by inserting the tip of the tongue piece 7 between the two spring wires 3, 3, and then wrapping it around it. Alternatively, the tongue piece 7 may be wrapped around one of the spring wires 3 in advance, and in this case, the workability when tightening the other spring wire 3 is improved. When the clip 6 is wound, the base of the tongue piece 7 is located inside the recess 8 as shown in FIG. 3, so there is no overlapping part and the clip is securely fastened. And two spring wires 3,3
Since they are separated via the tongue piece 7, they do not come into contact with each other, and generation of abnormal noise is prevented.

The clip 9 shown in FIG. 4 has a protrusion 10 provided on the tongue 7 side of the clip 6 shown in FIG. The protrusion 10 is formed by protruding the edge of a slit cut in the width direction. When the tongue piece 7 of this clip 9 is inserted between the two slit wires 3, 3, and wound and tightened, the protrusion 10 comes into pressure contact with one of the spring wires 3, as shown in FIG. rotation is prevented. This prevents the spring wire 3 and the clip 9 from rubbing against each other due to rotation, thereby further preventing the occurrence of abnormal noise.

The clip 11 shown in FIG. 6 has a tongue piece 12 with a curved portion 13 at its base. When the tongue piece 12 of this clip 11 is inserted between the two spring wires 3, 3 as shown in FIG. 7, and then wrapped and tightened, the curved part 1
3 is crushed and presses one spring wire 3.
As a result, the spring wire 3 is prevented from rotating more reliably, and the occurrence of abnormal noise is more reliably prevented.

The clip 14 shown in FIG. 9 has two tongue pieces 15a, 15b arranged side by side at one end, and a tongue piece 15a, 15b at the other end.
A convex portion 16 that can be engaged is formed between the tongue pieces 15b, and cuts 17a and 17 are formed between the tongue pieces 15a and 15b.
b is provided to form the projecting piece 18. Even if these two tongue pieces 15a, 15b are inserted between the two spring wires 3, 3 and wound around them, the protruding piece 18 is not bent and is pressed against one spring wire 3, as shown in FIG. Therefore, the spring wire 3
rotation is prevented, further preventing the occurrence of abnormal noise.

The clip 19 shown in FIG. 11 has cuts 21a and 21b on both sides of the base of the tongue piece 20, and
2a and 22b, and has the same effect as that shown in FIG.

(Effects of the invention) As is clear from the above explanation, if the spring wires are connected using the clip according to the invention, there is no contact between the spring wires, the occurrence of abnormal noise is prevented, and the spring wires are firmly secured without loosening. It has the effect of being tied together.
