[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The invention relates, for example, to a seat cover which rests on a car seat, in particular a bucket type seat.

[0002]

[Prior art]

 FIG. 7 is a perspective view showing a conventional seat cover placed on a bucket seat. The seat cover includes a backrest central portion 1 and a frame-shaped backrest outer peripheral portion 2 surrounding the outer periphery of the backrest central portion 1. The central portion 1 of the backrest is formed in a so-called bead cover body in which a number of wooden peas are knitted in the vertical and horizontal directions by inserting a thread. The backrest outer peripheral portion 2 is a bag body filled with a core material such as urethane foam, and is formed in a rectangular frame shape having a constant width and a constant thickness.

The central portion 1 of the backrest is located in the space of the outer peripheral portion 2 of the rectangular frame shape, and the central portion 1 of the backrest and the outer peripheral portion 2 of the backrest are fixed (sewed) by the inner edge tape 1A. It is formed. In FIG. 7, the rear side of the seat B is continuous with the lower end of the backrest A, and is integrally sewn with the outer edge tape 26.

As shown in FIG. 8, this seat cover is mainly placed on a bucket-type seat. Bucket-type seats are generally installed in the seats of automobiles, etc., and have a structure in which a certain width on both the left and right sides of the seat backrest is bulged forward. I am embracing.

[0005]

[Problems to be solved by the invention]

 As shown in FIG. 8, in the conventional seat cover, the outer periphery upper part, the outer periphery lower part, the outer periphery left part, and the outer periphery right part forming the backrest outer part 2 are formed in a continuous rectangular frame shape. In other words, the rectangular frame-shaped backrest outer peripheral portion 2 is configured to enclose a continuous rectangular frame-shaped elastic core material. Accordingly, when the backrest portion A is placed on the backrest C of the bucket type seat, the outer right and left portions of the outer periphery portion 2 of the backrest are bent inward by the left and right bulging portions C1 and C1 of the backrest C. Bend.

At this time, the bending force pulls the outer periphery upper part and the outer periphery lower part, particularly the corner part, which are continuous with the outer periphery right part and the outer periphery left part, inward, so that the outer periphery upper part is bent and deformed in a wave shape. As a result, there is a disadvantage that the backrest portion A does not fit the seatbackrest C, and if the occupant sits in the deformed state, the cover body easily collapses.

An object of the present invention is to solve the above-described problems and to provide a seat cover which is not allowed to be fitted properly to a bucket-type seat, and which does not easily lose its shape even after many years of use. I do.

[0008]

[Means for Solving the Problems]

 To achieve this purpose, the seat cover of the present invention has the following configuration. The seat cover is a seat cover including a central portion of the backrest and an outer peripheral portion of a frame-like backrest fixed to an outer periphery of the central portion of the backrest. The outer peripheral portion of the backrest is covered with a hard elastic core material. It consists of a wrapped outer periphery upper part, an outer periphery lower part, an outer periphery left part and an outer periphery right part. The inner part is fixed to the upper part of the outer periphery upper and lower left end upper parts, and the outer part right part is the outer part. It is characterized in that the inner part is fixed by polymerization to the upper surface of the right end of the upper and lower parts.

The seat cover having such a configuration is mainly placed on a bucket type seat. In the bucket-type seat, the left and right sides of the backrest have a constant width and bulge forward. In other words, it wraps around the flank of the occupant. Now, when the seat cover is placed on the bucket-type backrest, the center portion of the backrest corresponds to the center of the backrest of the seat, and the outer periphery of the backrest corresponds to the bulging portion of the backrest. With the center portion of the backrest in contact with the center of the seat backrest, the outer left portion and the outer right portion constituting the outer portion of the backrest are bent inward.

[0010] At this time, the outer peripheral left portion and the outer peripheral right portion are formed in a bag independent of the outer peripheral upper portion, and the outer peripheral left portion and the outer peripheral right portion overlap with the upper peripheral end upper surface (lower peripheral portion). It is sewn. Therefore, even if the outer left part (outer right part) is bent inward, this bending force does not act on the upper part of the outer periphery which is intermittent (not continuous). Therefore, the outer periphery upper part (outer periphery lower part) is correctly fitted to the center of the seat backrest, and only the outer periphery left part and the outer periphery right part are bent inward, so that the bulging part is properly fitted and mounted. Therefore, the correct appearance of the seat is maintained, and it is hard to lose its shape after many years of use.

[0011]

The backrest portion A includes a backrest central portion 1 and a backrest outer peripheral portion 2. In the embodiment, as shown in FIG. 3, the backrest central portion 1 is formed by inserting a tough thread 1b into a large number of wooden beads 1a provided with through holes in the axial direction, and arranging and fixing the peas 1a in the vertical and horizontal directions. To form a flat plate having a predetermined area. As shown in FIG. 2, a net-like sheet 2c of polypropylene or the like is joined and fixed to the back surface of the backrest central portion 1 as a reinforcing member.

As shown in FIG. 2, the backrest outer peripheral portion 2 includes an outer peripheral upper portion 21 having a predetermined width and length, an outer peripheral lower portion 22, an outer peripheral left portion 23, and an outer peripheral right portion 24. In the embodiment, the backrest outer peripheral portion 2, that is, the independent upper portion 21, lower portion 22, left portion 23, and right portion 24 are each made of a cloth (fabric) 2 a and have a predetermined thickness of an elastic core body (for example, hard urethane foam). ) 2b.

The outer peripheral upper part 21, the outer peripheral lower part 22, the outer peripheral left part 23, and the outer peripheral right part 24 are arranged so as to form a rectangular frame, and form a space part 25 in which the backrest central part 1 is appropriately fitted. I do. Then, an inner portion (inner edge) of the outer left portion 23, that is, an inner edge portion bordered by the folding tape 28 is superimposed on the upper surfaces of the left ends of the upper outer portion 21 and the lower outer portion 22, and sewn (stitching line). 28a).

Further, the inner part (inner edge) of the outer right part 24, that is, the inner edge part bordered by the bending tape 28 is superimposed on the upper surfaces of the right ends of the outer peripheral upper part 21 and the outer peripheral lower part 22, and sewn (suture line 28 a). )doing. As the folding tape 28, a synthetic resin tape having a fixed width or a hard cloth tape or the like is used in a two-fold shape.

A backrest disposed in a space 25 surrounded by an outer peripheral upper portion 21, an outer peripheral lower portion 22, an outer peripheral left portion 23, and an outer peripheral right portion 24 in which the inner elastic core material 2 b is discontinuously fastened. As shown in FIG. 3, the central portion (thread 1 b) 1 includes a fixing tape 27 sewn (sewn line 21 a) to the inner portion of the outer peripheral upper portion 21 and a fixing tape sewn to the inner portion of the outer peripheral lower portion 22. Sewn to the tape 27 and the folding tape 28 and fixed.

As shown in FIG. 1, the backrest A and the seat B are sewn by the outer edge tape 26 in a state where the rear end of the seat B is joined to the lower end (the outer peripheral lower part 22) of the backrest A. (The suture line 26a) is fixed.

Further, in the embodiment, as shown in FIG. 3, a bending preventing core bar (wire) 29 is provided inside each of the outer peripheral left portion 23 and the outer peripheral right portion 24. Specifically, it is wrapped around the tip of a folding tape 28 having a U-shape in cross section, which constitutes a rim of an inner portion (inner edge) of an outer left portion (right portion 24) 23. Has been fixed by.

The bend preventing core rod 29 is set to have a length from substantially the upper end to the lower end of the outer peripheral left portion 23 (outer peripheral right portion 24) excluding the outer edge tape 26. The core rod 29 prevents the backrest central portion 1 from being bent inward and breaking.

FIG. 5 is an exploded perspective view showing another embodiment of the backrest portion A. In the above embodiment, the backrest central portion 1 is a mat-like one in which beads 1a are knitted with yarns 1b in the vertical and horizontal directions. In this embodiment, the backrest has a four-layer structure of upper and lower layers. The central part 1 is illustrated.

The center portion 1 of the backrest includes a decorative mesh sheet 1c and a plate-like spring spring body 1e interposed between the upper and lower reinforcing mesh sheets 1d and 1f. A plate-shaped spring spring body 1e in which a flat linear spring is provided in the plane of a thin wire frame is formed in an area of the size of the space 25, and the decorative mesh sheet 1c, the upper and lower reinforcing mesh sheets 1d, 1e is formed in an enlarged shape so that the left and right widths are wider than the space portion 25 and extend over the outer peripheral left portion 23 and the outer peripheral right portion 24.

As shown in FIG. 6, in a state where the decorative mesh sheet 1c and the upper and lower reinforcing mesh sheets 1d and 1f are integrally laminated, the outer edge tape 26 (stitching) of the outer peripheral left portion 23 (outer peripheral right portion 24) is formed. The sewn at the line 26a) and the sewn with the bending tape 28 (sewn line 28a) inside the outer peripheral left portion 23 (the outer peripheral right portion 24). Therefore, the backrest center portion 1 is sewn and fixed on four sides in the vertical direction (left / right outer edge tape 26, left / right bending tape 28). Therefore, the surface of the central portion 1 of the backrest, which is formed by bending the outer peripheral left portion 23 and the outer peripheral right portion 24 inward via the folding tape 28, is prevented from rising forward and bulging.

The seat cover having such a configuration is mainly placed on a bucket-type seat. As shown in FIG. 4, the bucket-type seat is provided with bulging portions C1 and C1 bulging in a forward direction with a fixed width on both right and left sides of the backrest C. In other words, it wraps around the flank of the occupant.

Now, when the seat cover is placed on the bucket-type backrest C, the backrest central portion 1 is located at the center of the seatback, and the backrest outer peripheral portion 2 corresponds to the bulging portion C1 of the backrest C. To position. With the backrest central portion 1 in contact with the center of the seat backrest C, the outer peripheral left portion 23 and the outer peripheral right portion 24 forming the backrest outer peripheral portion 2 are each bent inward. That is, it is bent inward from the bending tape 28 as a starting point.

At this time, the outer peripheral left portion 23 and the outer peripheral right portion 24 are formed in the bag body (elastic core 2b) 2a independent of the outer peripheral upper portion 21 (the outer peripheral lower portion 22), and the outer peripheral left portion 23 and the outer peripheral right portion 24 are formed separately. And an outer peripheral right portion 24 is overlap-sewn on the upper surface of the end of the outer peripheral upper portion (outer peripheral lower portion 22) 21. Therefore, even if the outer peripheral left portion (outer peripheral right portion 24) 23 is bent inward, the bending force is in an intermittent state (not in a continuous state) and the outer peripheral upper portion 21 located on the opposite side to the bending direction. It does not act on (the outer peripheral lower part 22) at all.

Therefore, the outer periphery upper part (outer periphery lower part 22) 21 is correctly fitted to the center of the seat backrest, and only the outer periphery left part 23 and the outer periphery right part 24 are bent inward, so that the bulge part C 1 is correctly fitted. Fit fit. Therefore, the correct appearance of the seat is maintained, and it is hard to lose its shape after many years of use.
