  According to the first aspect of the present invention, when the clip is made of resin, the clip is fixed to the pad or the frame, and the corresponding portion of the pull-in member on the skin material side is inserted between the two pieces, the restriction protrusion and the engagement Since it is possible to retain and lock through the joint piece, compared to the conventional structure, the insert wire is not used, so the separation work at the time of disposal can be abolished, the weight increase caused by the insert wire can be reduced, and hoggling can be reduced. Compared to the conventional structure used, skill is not required and workability can be improved. In addition, the clip has first and second piece portions erected on the base portion, a restriction protrusion on the first piece portion side, and an engagement piece portion on the second piece portion side. The part can be passed to the base part side with the elastic displacement of the engaging piece part between the engaging piece part and the restricting projection, and after passing, it is elastically restored and prevented from coming off, so it is simple and the retracting member Can be restrained in a stable state.

  In the invention of claim 2, the engaging piece portion extends downward from the restricting projection, and the load is applied via the retracting member that enters the base portion side from between the restricting projection and the engaging piece portion and is prevented from coming off. In response, when the engaging piece is elastically displaced in the direction of escaping the retracting member, the engaging piece is constrained by the restricting projection, so that the retracting member can be constrained with a weak insertion force, and once constrained, it is difficult to come off.

  In the invention of claim 3, since the first piece portion is higher than the second piece portion, and the upper surface side of the restricting projection is a downward inclined guide surface, when the retracting member is inserted in the restraining direction as shown in FIG. First, since it is guided to the engagement piece portion side that is elastically displaced along the inclined surface of the restricting projection and is retained and locked, stable workability can be maintained.

  In the invention of claim 4, since the restricting projection is provided on the swingable small plate portion partitioned by the first piece portion through the slit, for example, when the base portion of the clip is insert-molded to the pad, the restricting projection is restricted. The protrusion and the engaging piece are forcibly displaced by a core or the like constituting the mold as shown by a two-dot chain line in FIG. 3A, and a pad is provided at least between the restricting protrusion and the engaging piece. It can be prevented from being formed. Further, if the lower surface side of the restricting projection is formed on a stopper surface substantially perpendicular to the small plate portion, when the engagement piece portion is elastically displaced as shown by a two-dot chain line in FIG. Therefore, inadvertent detachment of the retracting member can be surely eliminated.

  The inventions of claims 5 and 6 have been specified for confirmation. The retractable member according to claim 5 has a hole portion as compared with that of Patent Document 2, and the engaging piece portion is inserted into the hole portion, so that the clip can be restrained more stably and firmly. On the other hand, the clip according to claim 6 is versatile because it can be fixed in the state where the base portion is substantially embedded in the pad, that is, by the insert, or in the state where the base portion is in contact with the frame, that is, by welding. .

  The best mode of the present invention will be described below with reference to the drawings. In this description, the structure of the clip, its usage example, and modification examples will be described in detail.

(Structure) The skin locking clip 1 is fixed to the cushioning pad 3 or the frame 5 holding the pad as illustrated in FIG. 1 and covered on the pad 3 as shown in FIGS. The skin member 4 can be constrained to the pad 3 or the frame 5 side holding the pad in a state where the pull-in member 2 provided on the inner surface side of the material 4 is engaged by an insertion operation, that is, is locked out. .

  The pull-in member 2 is a resin-molded product, as shown in FIG. 2, a thin plate-like mounting portion 20, a bulging portion 21 provided along the lower edge of the mounting portion 20, and the mounting portion 20 and the bulging portion. It has a plurality of hole portions 22 provided at the boundary with the protruding portion 21. The attachment portion 20 is designed in a preferable mode for sewing processing such as a mesh or a non-woven fabric. The bulging part 21 should just be formed thicker than the attachment part 20, and a shape like the retainer 23 of patent document 2 may be sufficient as it. Each hole portion 22 may have a hole shape that allows the distal end portion of the engagement piece portion 17 to be described later to pass therethrough, and may be provided at a location other than the boundary between the attachment portion 20 and the bulging portion 21, that is, on the attachment portion 20 side. Good.

  The details of the clip are as follows. The clip 1 is an injection-molded product of resin, and includes a fixing base portion 10, a first piece portion 14 and a second piece portion 16 erected on the base portion 10 with a space therebetween, and a first piece portion. 14 is provided on the second piece 16 and protrudes toward the second piece 16 and extends diagonally downward, and the corresponding portion of the retracting member 2 is more elastic than the restriction projection 15. It has an engagement piece portion 17 that can pass to the base portion 10 side with displacement, and that is elastically restored after passage and is prevented from coming off.

  As shown in FIG. 4, the base portion 10 includes a substantially rectangular frame portion 11 provided at the center portion, hook-like or flange-like wing portions 12 and 12 provided on the left and right sides of the frame portion 11, and each wing portion 12. The reinforcing piece 13 connects the inside of both ends of the frame 11 and the left and right sides of the frame 11 or the first and second pieces 14 and 17 that are erected on the frame 11. Each wing part 12 is provided with a plurality of openings 12a penetrating vertically. An opening 13 a penetrating vertically is also provided inside the reinforcing piece 13.

  The 1st piece part 14 and the 2nd piece part 16 are maintaining the space | interval of the magnitude | size in which the above-mentioned bulging part 21 fits with a margin. The first piece 14 protrudes on the front and rear pieces of the frame 11 and is higher than the second piece 16. Further, the first piece portion 14 is substantially U-shaped as shown in FIG. 5C, and has a small plate portion 18 that is partitioned from both sides of the U-shaped intermediate portion through slits 14a on both sides and can swing. In addition, the restricting protrusion 15 is provided on the small plate portion 18. As shown in FIG. 4B, the restricting projection 15 is formed on a guide inclined surface 15a that is inclined downward so that the upper surface side is closer to the tip, and the lower surface side is a horizontal shape that is substantially perpendicular to the small plate portion 18. It is formed on the stopper surface 15b.

  As shown in FIG. 5 (b), the second piece 16 has a substantially U-shaped portion protruding on the front and rear pieces of the frame portion 11, and a connecting plate portion 16a provided so as to fill the inside of the U-shaped portion. have. And the above-mentioned engaging piece part 17 is extended diagonally downward from the upper end of the connecting plate part 16a, and the protruding end is located below the restricting protrusion 15 as shown in FIG. There is a slight gap between them. When the engagement piece 17 is elastically displaced in a direction in which the pull-in member 2 is released by receiving a load via the pull-in member 2 which is inserted between the restricting protrusions 15 and is prevented from coming off, that is, in an upward direction, the restricting protrusion 17 15 stopper surfaces 15b are abutted and regulated.

(Usage example) Although the above-mentioned clip 1 assumes a seat or a seat as in Patent Documents 1 and 2, it can be used in a field where a cushioning pad is covered with a skin material other than the seat. Further, the clip 1 is not limited to the mode of being fixed to the pad 3 as shown in FIG. 1B, and may be fixed to the frame 5 holding the buffer pad as shown in FIG. 1C.

  1B, the clip 1 is schematically illustrated in FIG. 2, for example, on the bottom surface 32 side of the concave groove 30 provided between the pad main portion and the pad side portion of the pad 3. It is fixed by the insert at the time of pad molding. The groove portion 30 is partitioned by both side surfaces 31 and a bottom surface 32. Normally, the base portion 10 of the clip 1 is inserted into the pad corresponding portion when the pad 3 is formed of urethane foam resin or the like as shown in FIG. In this structure, the wing parts 12 on both sides of the base part 10 are completely embedded in the pad 3, and the resin stock solution enters the frame part 11 and the openings 12a and 13a so as to be firmly fixed and integrated. It has become. When the clip 1 is insert-molded into the pad 3, the restricting protrusion 15 and the engaging piece 17 are forcibly formed by a core constituting the forming die as shown by a two-dot chain line in FIG. So that a pad is not formed at least between the restricting projection 15 and the engaging piece 17.

  In the embodiment of FIG. 1C, the clip 1 is fixed to the side wall 50 of the frame 5 holding the pad by welding. The frame 5 is assumed to be a pan-type frame as shown in FIG. 7, for example, but may be any core material that holds a buffer pad.

  The target skin material 4 is omitted in detail, but usually has a structure in which the skin layer is lined with a wadding layer or the like as in the prior art, and the corresponding end portion 40a of the skin portion 40 and the corresponding end portion of the other skin portion 41 It has the connection part 44 which joined 41a by sewing etc. In the pulling member 2 described above, the attachment portion 22 is attached to the connection portion 44 by the sewing portion 23 or the like.

  2 and 3 show an operation example in which the skin material 4 is engaged with the clip 1 fixed to the pad 3 via the retracting member 2. In this case, the retracting member 2 has a corresponding hole 22 on each of the clips 1 on the pad side, and a bulging portion 21 between the first piece portion 14 and the second piece portion 16 on the clip side. It is pushed in the direction of the arrow in FIG. Then, in this structure, the bulging part 21 pushes the engaging piece part 17 and is inserted between the two piece parts 14 and 16 while elastically displacing the engaging piece part 17 downward, that is, in the direction of narrowing the projection angle, In the process, as shown in FIG. 3B, the tip of the engagement piece 17 is inserted from one side of the hole 22 to the other side.

  In other words, the engagement piece 17 holds and locks the retracting member 2 in a state of being inserted into the hole 22 as shown in FIG. In this structure, the engaging piece 17 extends downward from the restricting projection 15 as shown in the figure. For example, the pulling member 17 is applied to the skin material 4 due to the tension in the direction of the arrow in the figure. When it is elastically displaced in the direction of widening the angle in response to a load in the unlocking direction, it is restricted from hitting the restricting protrusion 15 and being excessively deformed. As a result, in this structure, the retracting member 17 is inserted and engaged with a relatively weak insertion force between the restricting protrusion 15 of the first piece portion and the engaging piece portion 17 of the second piece portion 16, so that the skin material 4 is It can be restrained to the pad 3 side, and once restrained, it is difficult to come off.

(Modification) FIG. 6 shows a modification in which a plurality of the clips 1 described above are integrally provided. In this description, the same reference numerals are assigned to the same portions as those in the above-described embodiment, and only the changed points with the new reference numerals are described in detail. That is, this clip 6 has a mode in which the clip 1 and the clip 1 are connected by the intermediate piece 12b. Each wing 12 and each intermediate piece 12b are provided with openings 12a penetrating vertically at substantially equal intervals. The opening 12a is designed to be larger than the above form. In this clip 6, since the plurality of clips 1 can be handled at the same time, the handling property and the operability of being integrated to the pad or the frame side are excellent.

  It should be noted that the present invention is only required to have the configuration specified in the claims, and the details can be variously changed as necessary as in the modification.
