Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a clip for attaching a panel to a seat bag, etc., which is used, for example, when attaching a panel to a seat bag of an automobile. This relates to an improved connection with a wire.

[Prior art]

Conventionally, when attaching a panel to a car seat bag with clips, for example, as shown in FIG. 3, a pipe frame 2 and a bracket 3 welded to the pipe frame 2 are provided inside the seat 1. The legs of the clip 5 are press-fitted into the fitting holes 4 formed in the clip 3. A protrusion 6 is formed on the circumferential surface of the leg portion of the clip 5 and is crushed when the clip 5 is fitted into the fitting hole 4. In this conventional structure for attaching the panel to the seat bag, when a force is applied to the clip 5 to pull the clip 5 out of the fitting hole 4, the outer circumferential surface of the clip 5 comes into close contact with the circumferential surface of the fitting hole 4. A frictional resistance is created that attempts to prevent the clip from being pulled out, and when this frictional resistance is greater than the force that attempts to pull the clip 5 out of the fitting hole 4, the clip 5 is prevented from being pulled out.

[Problem that the invention attempts to solve]

However, once this protrusion 6 is crushed, it is deformed to the extent that it is almost impossible to recover. Therefore, the clip 5 that was once fitted into the fitting hole 4 is pulled out from the fitting hole 4, and the clip 5 is inserted into the fitting hole 4 again. If used together, the adhesion force of the leg to the fitting hole 4 will not be obtained,
The clip 5 easily falls out of the fitting hole 4. Therefore, such a conventional clip 5 has the disadvantage that it cannot be reused. Furthermore, the fitting between the clip 5 and the bracket 3 is maintained only by the frictional resistance generated from the adhesion of the legs of the clip 5 to the circumferential surface of the fitting hole 4, and the clip 5 is relatively easily fitted. It also has the disadvantage that it can be pulled out from the fitting hole 4. The present invention was devised under these circumstances; it can be attached to and detached from seat bags etc. with a simple operation, and it can be reused repeatedly.
Moreover, the present invention aims to provide a clip for attaching a panel to a seat bag or the like, which will not be easily pulled out by a simple pulling force.

[Means to solve the problem]

In this invention, in order to solve the above problems,
The following technical measures will be taken: That is, the leg of the clip has an inclined guide surface extending obliquely from the distal end of one side of the leg toward the proximal end of the other side, and the inclined guide surface and a predetermined wire on the other side of the leg. an insertion/extraction guide surface disposed at a location with an insertion space and extending from the distal end of the leg in the axial direction toward the proximal end of the leg relative to the other side of the inclined guide surface; and the one side of the leg. an engagement surface that receives a wire disposed on a seat bag or the like from the distal end side of the inner end of the insertion/extraction guide surface; An engagement guide surface for guiding is provided.

[Effect]

When the clip is pushed toward the trimming wire of a seat bag, for example, the trimming wire is guided by the inclined guide surface into the trimming wire insertion space, and from this trimming wire insertion space, it advances further toward the proximal end along the insertion/extraction guide surface. .
Then, the trimming wire, which has been displaced from one side of the leg to the other side by the inclined guide surface, moves the clip from one side to the other side by its self-restoring force. By moving it toward the engagement surface, it is guided by the engagement guide surface. In this way, the engagement surface of the clip is brought into engagement with the trimming wire. Since the clip receives the trimming wire from the tip side of the leg, it will not be easily pulled out even if an external force is applied in the direction of simply pulling out the clip. Rather, when a force is applied to the clip in the pulling direction, such as the elastic restoring force of the trimming wire or the tension of the seat skin member, the engaging surface is located at the one side of the leg and further forward than the inner end of the insertion/extraction guide surface. Since the side is configured to receive the trimming wire of a seat bag or the like from the distal end side, the engagement between the clip and the trimming wire becomes more reliable. When the clip engaged with the trimming wire is pushed in and moved from the other side to the one side, the trimming wire is received at the rear end of the insertion/extraction guide surface. When the clip is pulled out as it is, the trimming wire passes through the trimming wire insertion space and comes out to the outside of the clip.

【effect】

As explained above, according to the present invention, the clip can be attached to and detached from a seat bag etc. by a simple operation such as pushing the clip in or pushing it in and simultaneously moving it in one direction, thereby improving serviceability. Further, since the clip and the wire are connected by engaging the clip with the wire, the clip does not undergo plastic deformation, and the clip can be repeatedly reused. Furthermore, since the clip is engaged with the wire, there is no fear that the clip will be pulled out even if an external force is applied to the clip in the pulling direction. is obtained. In addition, it is possible to omit a bracket such as a seat bag, thereby making it possible to reduce the cost of the seat bag.

[Explanation of Examples]

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. In this example, the present invention is applied to a clip for attaching a back panel using a trimming wire for fixing the skin to the back of the backrest of an automobile seat. First, the backrest 10 of an automobile seat includes a pipe frame 11, a cushion material 12, a front fabric 13, and a trimming wire 14 for pressing the periphery of the front fabric 13. The panel 15 attached to the rear surface of the backrest 10 of this seat is
The clips are extended further to the peripheral edge of the backrest 10 than the trimming wire 14, and clip insertion holes 1 are provided at a plurality of locations facing the trimming wire 14.
6. The clip 17 consists of a leg part 18 and a head part 19 formed with a larger diameter than the leg part 18. The distal end surface of the leg portion 18 forms an inclined guide surface 20 that is inclined toward the proximal end from one side toward the other side. A trimming wire insertion space 21, which is slightly smaller than the wire diameter of the trimming wire 14, is disposed on the inclined guide surface 20 on the other side of the leg 18, and is arranged from the tip of the leg 18 to the axial center. An insertion/extraction guide surface 22 is formed that extends in the direction toward the proximal end of the leg section 18 from the other side edge of the inclined guide surface 20. An engagement surface 23 is formed on one side of the leg 18 to receive the trimming wire from the tip at a position that is further back toward the tip of the leg than the edge of the other side of the inclined guide surface 20. This engagement surface 23 is connected to the engagement guide surface 2 from the other side edge of the inclined guide surface 20.
It is made consecutive with 4. Further, an engagement release guide surface 25 is provided opposite the engagement guide surface 24 . Further, on one side of the head 19 there is a marking 2 indicating the direction of the engaging surface 23 of the clip 17.
6 is formed. The leg portion 18 of the clip 17 passes through the clip insertion hole 16 to the trimming wire 14 of the backrest 10.
He was forced into the room. As this pushing progresses, the trimming wire 14 is received by the inclined guide surface 20, slides on this inclined guide surface 20, is guided into the trimming wire insertion space 21, and is guided from this trimming wire insertion space 21 along the insertion/extraction guide surface 22. Proceed to the proximal end of this. The trimming wire 14 is elastically deformed by being guided by the inclined guide surface 20, and when it passes through the trimming wire insertion space 21 and reaches the base end of the insertion/extraction guide surface 22, it is engaged by its elastic restoring force. Amen 2
Displaced to the 3rd side. When the clip 17 is released, the clip 17 is pushed in the pulling direction by the panel 15 which is pushed backward by the tension of the outer fabric 13. However, since the trimming wire 14 is already positioned on the head side of the engagement guide surface 24, the trimming wire 14 is
4, and the clip 17 is not pulled out from the clip insertion hole 16. Furthermore, when the clip 17 continues to be pushed backward, the trimming wire 14 is moved between the engagement surfaces 24 and 24 by the engagement guide surface 24.
3, the engaging surface 23 of the clip 17 is brought into engagement with the trimming wire 14. When the clip 17 is engaged with the trimming wire 14, the clip 17 receives the trimming wire 14 from the tip side of the leg, so even if an external force is applied in the direction of simply pulling out the clip 17, the clip 17 will not be pulled out. There isn't. Rather,
When force is applied to the clip 17 in the pulling direction through the panel 15 due to the elastic restoring force of the trimming wire 14 or the tension of the sheet skin member,
The contact pressure between the engagement surface 23 and the trimming wire 14 is increased, and the engagement between the clip 17 and the trimming wire 14 becomes more reliable. When the clip 17 engaged with the trimming wire 14 is pushed in, the trimming wire 14 is received by the disengagement guide surface 25, guided by this, and received by the inner end of the insertion/extraction guide surface 22. In this position, the trimming wire insertion space 21 is opened at the tip end of the leg of the trimming wire 14, so that the clip 17 can be pulled out. Note that if the clip 17 is pushed in and moved simultaneously in the direction of the marking 26, the trimming wire 14 can be moved from the engagement surface 23 of the trimming wire 14 to the inner end of the insertion/extraction guide surface 22. This allows for easier and faster movement. In this way, the clip 17 can be easily engaged with the trimming wire 14 by simply pushing the clip 17, and can be easily engaged with the trimming wire 14 by simply pressing the clip 17 in the direction of the marking 25 on the head 19. The clip 17 can be pulled out by releasing the engagement. By attaching and detaching the clip 17, the clip 17
does not cause any plastic deformation, so this clip 1
7 can be reused over and over again. Moreover, the clip 17 is attached to the trimming wire 14.
Therefore, even if an external force acts in the direction of simply pulling out the clip 17, the clip 17 will not be pulled out, and a strong holding force can be obtained. Of course, the present invention is not limited to the above embodiment; for example, the inclined guide surface 20 and the engagement guide surface 24 may be formed parallel to each other.
Furthermore, the engagement surface 23 may be recessed further toward the distal end side of the leg portion 18 than the engagement guide surface 24 . Furthermore, the clips of the present invention can be used to attach panels, etc., regardless of the object; in addition to attaching panels using the trimming wire of the seat backrest as in the embodiment, this invention also applies when attaching panels using S springs. included in the scope of invention.
