  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated using drawing.

  First, the configuration of the clip 50 according to the first embodiment will be described with reference to FIGS. As shown in FIG. 1, the clip 50 of the present embodiment has a part of the skin material 30 covered on the surface of the seat back 2 of the vehicle seat 1 fixed to the back frame 10 that forms the skeleton of the seat back 2. It functions as a device for hooking and fixing to the horizontal wire 16A. Here, the vehicle seat 1 is configured as a rear seat of a vehicle having two rows of seats, and includes a seat back 2 that serves as a backrest for a seated occupant, a seat cushion 3 that serves as a seating portion, and a headrest. The headrest 4 which becomes.

  The seat back 2 described above is supported by connecting the lower end portions of the left and right sides thereof to the rear end portions of the left and right sides of the seat cushion 3. The seat cushion 3 is connected and supported on the floor. The headrest 4 is attached and fixed to the upper part of the seat back 2. The back frame 10 that forms the skeleton of the seat back 2 described above is configured by bending a circular steel pipe into a square frame shape and joining it in an endless manner, and both side frames forming the skeleton on both the left and right sides of the seat back 2. 12, an upper frame 11 that forms the skeleton of the upper portion of the seat back 2, and a lower frame 13 that forms the skeleton of the lower portion of the seat back 2.

  On the above-described upper frame 11, square cylindrical holders 15 are integrally welded and fixed at two positions on the left and right sides of the center. These holders 15 are portions for mounting and fixing cylindrical support members 14 for inserting and mounting two rod-like stays 4A provided so as to protrude from the lower surface portion of the headrest 4 respectively. ing. By inserting and mounting the stays 4A of the headrest 4 on the support members 14 mounted on the holders 15, the headrest 4 is held in a state of being fixed to the upper portion of the seat back 2. .

  The back frame 10 is provided with a plurality of linear horizontal wires 16A extending in the sheet width direction and a plurality of linear vertical wires 16B extending in the height direction. It has been. These horizontal wires 16A and vertical wires 16B support a mat-type back pad 20 serving as a cushioning material that covers the front surface of the back frame 10 from the rear side, or a resin back that covers the rear surface of the back frame 10. The board 40 functions as one that is hooked and fixed using clips 50 and 60 described later. Here, the horizontal wire 16A corresponds to the “hanging wire” of the present invention, and the vertical wire 16B corresponds to the “obstacle” of the present invention.

  The vertical wire 16B that is bent into an inverted U shape extending from the lower side toward the center side inside the frame of the back frame 10 has an anchor portion whose tip is bent in an inverted U shape on the rear side. It is configured as 16C and functions as a top tether anchorage for hooking a strap (top tether) for fixing a child seat (not shown). The anchor portion 16C is directed so as to protrude rearward and obliquely upward, and is passed from the through hole 43 formed in the backboard 40 that covers the rear surface of the back frame 10 to the rear side of the backboard 40. After that, the cap 44 is fitted into the through-hole 43 so that the gap around the cap 44 is filled, and the cap 44 is projected from the back board 40 to the rear side.

  The back pad 20 described above is formed of urethane foam, and is set from the front side so as to straddle the square frame of the back frame 10, so that it extends to the rear side formed in each of the upper, lower, left and right peripheral portions. Each extending portion 20A to be extended is set so as to cover the back frame 10 as being turned from the outside of each frame portion of the back frame 10 to the rear side. By the above assembly, each frame portion of the back frame 10 is covered from the front surface side by the back pad 20 and is also covered from the outer peripheral surface side and the rear surface side by each extension portion 20A of the back pad 20 respectively. It has become so.

  After the back pad 20 is assembled to the back frame 10, a cloth skin material 30 is applied to cover the entire surface of the back pad 20. Specifically, as shown in FIGS. 1 to 2, the skin material 30 includes a front side skin 31 that covers the front surface of the seat back 2 and a back side skin 32 that covers the rear surface of the seat back 2. The front-side skin 31 is placed on the front surface of the seat back 2 (the front surface of the back pad 20), and its upper, lower, left, and right peripheral edges are turned to the rear side and are provided integrally with the back frame 10. The hooks are hooked and fixed respectively.

  Among these, as shown in FIG. 5, the edge portion 31A of the front side skin 31 that is turned from the upper side of the seat back 2 to the rear side is more specifically, the upper edge portion 32A of the back side skin 32 on the same edge portion 31A. And the resin clip 50 are sewn together (stitched portion 30A), and the hook portion 52 of the clip 50 is hooked and fixed to the horizontal wire 16A spanned on the upper region in the back frame 10 described above. As a result, the rear side of the seat back 2 is pulled into the front lower side and is fixed. Thereby, the front side skin 31 is made into the state coat | covered in the state closely_contact | adhered to each extension part 20A of the back pad 20, without producing a float and a wrinkle. Further, after the back board 40 is attached to the rear surface of the back frame 10, the back side skin 32 is covered so as to cover the entire back surface of the back board 40, and the lower edge thereof is pulled downward. Thus, the state is fixed by being hooked on the frame structure of the seat cushion 3 (not shown).

  The back board 40 described above is attached and fixed to the back frame 10 as follows. That is, the backboard 40 inserts the upper edge portion 41 into the above-described clip 50 from below and sandwiches it, and the clips 60 attached to the left and right portions of the lower portion are placed in the lower region in the back frame 10. The upper and lower portions are fixed to the back frame 10 by being pushed and elastically hooked into the crossed horizontal wire 16A. Specifically, the two clips 60 attached to the lower portion of the backboard 40 described above are inserted into attachment holes 42 formed at two positions on the left and right sides of the lower portion of the backboard 40 as shown in FIG. Each is inserted and attached, and each side wire 16A is elastically received and clamped by being pushed into a horizontal wire 16A spanned in a lower region in the back frame 10, respectively. It has become.

  On the other hand, the clip 50 that holds the upper edge portion 41 of the backboard 40 is formed in a horizontally long shape that is long in the sheet width direction in which the horizontal wire 16A extends (see FIGS. 2 to 4). Thus, it is configured to be hooked and fixed in a widely engaged state in the sheet width direction. Specifically, as shown in FIG. 5, the clip 50 is integrally formed by injection molding of a polypropylene resin, and is joined together by stitching together with the stitching portion 30 </ b> A of the skin material 30 described above. And a hook-like hook portion 52 that is hooked and fixed to the horizontal wire 16A from the lower side, and a planar cover portion 53 that is formed at a position facing the back side portion 52B of the hook portion 52. Are formed in a vertically long cross-sectional shape.

  The above-described skin joint portion 51 is formed in a vertically long surface shape, and along the upper edge portion of the surface portion extending in a long shape in the sheet width direction, the above-described stitched edge portion 31A of the skin material 30, 32A is widely applied in the sheet width direction and stitched and joined. The hook portion 52 is formed in a stepped shape from the lower end side portion of the skin coupling portion 51 to the front lower side, and from there, the shape warps in a bowl shape toward the front end side portion 52A. ing. The tip side portion 52A is formed to be bent obliquely upward and obliquely upward, and this inclined shape widens a bowl-shaped opening for receiving the horizontal wire 16A from the upper side, so that the horizontal wire 16A is positioned on the upper side. Makes it easy to accept inside.

  Further, the hook portion 52 is formed with a planar fin portion 52C extending downward along a lower end side portion of the flange-like portion extending in the sheet width direction. As shown in FIG. 5, when the hook 52 is hooked and fixed to the horizontal wire 16A, the fin portion 52C is another horizontal portion provided in parallel with the lower position of the horizontal wire 16A. It is applied to the wire 16 </ b> A from the rear side and functions to maintain the posture of the clip 50.

  That is, by pulling the clip 50 in a state in which the skin material 30 is stitched to the above-described skin joint portion 51 to the front lower side and hooking the hook portion 52 to the lateral wire 16A and fixing it, Due to the tension action of the skin material 30, the skin coupling portion 51 is applied with a force that is obliquely pulled upward in the rear upper direction, which is the direction in which the skin material 30 is stretched, with the horizontal wire 16A hooked by the hook portion 52 as a fulcrum. . By this pulling force, a force that is pushed forward is applied to the fin portion 52C around the horizontal wire 16A on which the hook portion 52 is hooked. However, the fin portion 52C is prevented from rotating in the forward direction by being applied to the horizontal wire 16A arranged on the front side thereof, and the posture of the clip 50 by being pressed against the horizontal wire 16A. Is held at a fixed position.

  The covering portion 53 is formed in a vertically long surface shape that hangs straight down from the lower end side portion of the above-described skin joint portion 51 and forms one surface shape with the skin joint portion 51. As a result, the upper edge 41 of the backboard 40 is inserted and fitted between the cover 53 and the back portion 52B (and fin 52C) of the hook 52 described above. A holding space 54 having a front and rear width that can be formed is formed. By inserting the upper edge portion 41 of the backboard 40 from the lower side into the sandwiching space 54 described above, the upper edge portion 41 of the backboard 40 is moved back and forth by the rear portion 52B of the hook portion 52 and the cover portion 53. Is held in an elastically sandwiched state. That is, the upper edge portion 41 of the backboard 40 is held in a fixed position without fluttering by being sandwiched and held between the clips 50 held in a posture by engaging the two horizontal wires 16A described above. Are to be held.

  Further, the clip 50 has rectangular through windows 52D and 53B penetrating the hook portion 52 and the cover portion 53 by punching with a press at various locations in the sheet width direction (see FIG. 2 to FIG. 4). As shown in FIGS. 6 to 8, these through windows 52 </ b> D and 53 </ b> B cross the hook portion 52 close to the horizontal wire 16 </ b> A when the hook portion 52 is hooked and fixed to the horizontal wire 16 </ b> A from the lower side. In order to avoid interference with a plurality of vertical wires 16B provided in the state and various equipment (not shown) provided in the back frame 10, it is formed as a lightening portion that avoids interference with these obstacles. It is what. In the region where the through windows 52D and 53B are formed, the protruding shape protruding in a hook shape of the hook portion 52 is removed, so that the hook portion 52 does not interfere with an obstacle such as the vertical wire 16B. .

  As shown in FIGS. 6 to 8, the cover portion 53 described above is further formed with an opening 53 </ b> A that communicates with the through window 53 </ b> B and widens the opening shape of the through window 53 </ b> B in the width direction. In the present embodiment, the opening 53A is formed so as to communicate with each of the through windows 53B (see FIG. 4), and the back side portion 52B of the hook portion 52 covers the back surface of the portion 53 by each opening 53A. You can see from the side. More specifically, each of the openings 53A is formed in a shape that opens wider in the height direction than the through windows 52D and 53B that are penetrated through the hook shape of the hook portion 52 and the cover portion 53. Through the opening 53A, the state when the hook portion 52 is hooked on the horizontal wire 16A and the state after the hook are hooked can be seen from the rear side.

  Specifically, the hook portion 52 has a translucent structure because the clip 50 is formed of polypropylene resin, and the hook portion 52 is viewed from the back side through each opening 53A. It is easy to visually check whether 52 is hooked on the horizontal wire 16A. Further, since each of the openings 53A is formed to communicate with each of the through windows 53B, the shape of the end portion cut by each of the through windows 52D of the hook portion 52 can be seen from each of the openings 53A. ing. Therefore, the shape of the horizontal wire 16A itself and the shape of each end portion of the hook portion 52 facing each through window 52D, 53B can be seen through these through windows 52D, 53B. It is possible to appropriately visually check whether or not the hook is hooked on the hook portion 52.

  As described above, according to the clip 50 of the present embodiment, the opening 53A for visualizing the rear side portion 52B of the hook portion 52 is formed in the cover portion 53, so that the hook portion 52 is pulled to the horizontal wire 16A through the opening 53A. Whether or not it is hung can be seen from the back side of the covering portion 53. Thereby, it is possible to easily visually check whether or not the hook portion 52 is hooked on the object (the horizontal wire 16 </ b> A) from the back side of the cover portion 53.

  In addition, since each opening 53A is formed to communicate with each through window 53B formed in the cover 53, the end facing the through window 52D of the hook 52 is hooked to the horizontal wire 16A from each opening 53A. You will be able to peek at the status of whether or not This makes it possible to more appropriately visually check whether or not the hook portion 52 is hooked on the object (the horizontal wire 16A). Further, the configuration in which the opening 53A is formed in communication with the through windows 52D and 53B for avoiding interference formed through the hook portion 52 and the cover portion 53, the end portion of the hook portion 52 as described above is formed. The structure which exposes a shape and can perform visual confirmation more appropriately can be rationally formed in one place. Further, by forming each opening 53A larger than the hook shape of the hook portion 52, it is possible to more appropriately visually check whether the hook portion 52 is hooked on the horizontal wire 16A.

  The clip 50 uses the flexibility, for example, when the horizontal wire 16A to which the hook portion 52 is hooked is routed in a curved state, in accordance with the shape of the horizontal wire 16A. It may be bent and bent so as to be hooked. In this way, even when it is difficult to hook the hook portion 52 on the horizontal wire 16A while bending back, it is possible to look into the rear side portion 52B of the hook portion 52 as in this embodiment. As a result, the operation of hooking the hook portion 52 to the horizontal wire 16A can be performed while visually confirming, the hooking operation can be easily performed, and the hook portion 52 is attached to the horizontal wire 16A. It is possible to appropriately check whether or not it has been caught.

  As mentioned above, although the embodiment of the present invention has been described using one example, the present invention can be implemented in various forms in addition to the above example. For example, the object to which the hook portion of the clip is hooked is not limited to the linear wire (lateral wire 16A) as shown in the above embodiment. The hook portion may be hooked on a frame edge or a hole formed in the frame. Further, the clip may have a short shape regardless of whether or not the shape of the object to be hooked is a long shape. For example, when the structure shown in the above embodiment is described as an example, a plurality of clips having a short shape in the sheet width direction are coupled to the skin material 30, and the plurality of clips are hooked and fixed to the lateral wire 16A. It may be a thing.

  In addition, the clip of the present invention is used for hooking and fixing the skin material of the vehicle seat to the frame structure, the other parts in the seat back 2 shown in the above embodiment, the seat cushion 3 and the headrest 4. It can be applied to various locations such as the inside location. Moreover, the opening formed in the clip does not necessarily need to be formed in communication with a through window formed through the hook portion and the cover portion. An opening may be formed in a part without a through window or in a place away from the through window. Moreover, the opening may be formed to have the same opening width as the through window or smaller than the through window. In addition to the rectangular shape, various shapes such as a circle, an inverted triangle, and a bowl shape can be applied to the shape of the opening. Moreover, in the said Example, although what formed the clip 50 translucent with the polypropylene resin was illustrated, resin which is not translucent may be sufficient and it may be formed with the metal material.
