Summary of the Invention

Problems to be Solved by the Invention

[0004] In the case of an automobile seat, it is necessary to satisfy the requirements for internal protrusions stipulated in the UN / ECE regulations (United Nations Economic Commission for Europe regulations), which are regulations for protecting rear seat passengers. Therefore, when the resin engaging tool and the engaged tool as described above do not satisfy the requirements for internal protrusions, it is necessary to appropriately cover them using a covering member such as felt.

[0005] In that case, if a covering member is set individually for the engaging tool and the engaged tool, the number of parts may increase and the assemblability may deteriorate. Therefore, the present invention provides a seat cover capable of reasonably covering each edge of the engaging tool and the engaged tool for fixing the cover terminals to each other with a covering member.

Means for Solving the Problems

[0006] As means for solving the above problems, the seat cover of the present invention takes the following means.

[0007] That is, a first invention of the present invention is a seat cover having one cover terminal and the other cover terminal that are attracted to and fixed to each other, the base being sewn so as to extend in the cover width direction along the one cover terminal, and a hook portion extending so as to be bent back from the tip of the base in the pulling direction to the outer surface side of the cover, and the other cover terminal is sewn so as to extend in the cover width direction on the inner surface side of the cover, and the other cover portion including the other cover terminal is inserted between the base and the hook portion of the hook member with inversion so as to be bent back to the inner surface side of the cover, and the hook portion is hooked against the tension caused by the pulling of the other cover terminal, and a covering member sewn to the other cover portion and having a first covering portion extending so as to cover one edge in the cover width direction of the hook portion, the base portion, and the hooked member from the outer surface side of the cover along the inner peripheral surface of the bent-back surface portion of the other cover portion that is bent back.

[0008] According to the first invention, the covering member provided only on the other cover portion can appropriately cover each edge on one side in the seat width direction of the hooking member and the hooked member together from the outer surface side of the cover.

[0009] A second invention of the present invention is the seat cover according to the first invention, wherein the covering member further has a second covering portion extending so as to cover the edge of the base from the outer surface side of the cover along an insertion region inserted between the base and the hook portion of the bent-back surface portion from the first covering portion.

[0010] According to the second invention, the edge of the base of the hooking member can be covered by both the first covering portion and the second covering portion.

[0011] The third invention of the present invention is, in the second invention, a sheet cover in which the other cover terminal is sewn along the tip in the insertion direction of the hooked member together with the second covering portion.

[0012] According to the third invention, the second covering portion can be provided so as to widely cover the edge of the base of the hooking member from the tip side in the insertion direction. Further, the covering member and the hooked member can be sewn with reference to the edge of the other cover terminal. Furthermore, since these sewing portions are located at the tip of the hooked member inserted between the base and the hook portion of the hooking member, it is possible to make it difficult to expose the sewing portions to the outside.

[0013] The fourth invention of the present invention is, in any one of the first to third inventions, a sheet cover in which the first covering portion protrudes to the one side in the cover width direction from the hooked member, and the hooked member protrudes to the one side in the cover width direction from the hooking member.

[0014] According to the fourth invention, since the first covering portion is configured to protrude further than the hooked member that protrudes to one side in the cover width direction from the hooking member, it is possible to more reliably cover the edges of the hooking member and the hooked member from the outside of the cover.

[0015] The fifth invention of the present invention is, in any one of the first to third inventions, a sheet cover in which the covering member is provided separately on both sides excluding the central portion in the cover width direction of the other cover portion so as to cover each of the hook portion, the base portion of the hooking member, and each of the edges on one side and the other side in the cover width direction of the hooked member from the outside of the cover.

[0016] According to the fifth invention, while appropriately covering the edges of the hooking member and the hooked member with the covering member, it is possible to appropriately suppress the enlargement of the covering member.

Mode for Carrying Out the Invention

[0018] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

[0019] 《First Embodiment》 (Schematic Configuration of Seat Cover 1) First, the configuration of the seat cover 1 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 6. In the following description, when indicating directions such as front, rear, up, down, left, and right, the respective directions shown in each figure shall be referred to. Further, in the following description, when no specific reference figure is shown, or when there is no reference numeral corresponding to the reference figure, any one of FIGS. 1 to 6 shall be appropriately referred to.

[0020] As shown in FIGS. 1 to 2, the seat cover 1 according to the present embodiment is applied to a seat back SB that forms the backrest portion of an automotive seat. The seat back SB has a seat cover 1 made of synthetic leather that is placed on the seat surface. The seat cover 1 is formed in a bag shape so as to be placed on the seat back SB from above.

[0021] Specifically, the seat cover 1 is sewn such that a plurality of cover pieces cut according to the shape of each surface of the seat back SB form a single bag shape. The seat cover 1 has a back cover piece 2 that is placed on the back surface of the seat back SB and a bottom cover piece 3 that is placed so as to be drawn backward through the lower surface of the seat back SB, and they are joined to each other at the lower part of the back surface of the seat back SB.

[0022] As shown in FIGS. 3 to 4, specifically, a hook 4 made of a resinous horizontally long plate-like member is sewn to the back cover piece 2 along the lower cover terminal 2A thereof. Further, a hooked member 5 made of a resinous horizontally long plate-like member is sewn to the bottom cover piece 3 along the upper cover terminal 3A thereof. Here, the bottom cover piece 3 corresponds to the "other cover part" of the present invention. Also, the cover terminal 2A corresponds to the "one cover terminal" of the present invention, and the cover terminal 3A corresponds to the "other cover terminal" of the present invention.

[0023] The back cover piece 2 and the bottom cover piece 3 are fixed in a state where the respective cover terminals 2A and 3A are drawn close to each other by inserting the hooked member 5 into the hook 4 from the rear upper side and hooking it. The hook 4 and the hooked member 5 are each formed by punching an injection-molded resin part into a predetermined length.

[0024] As shown in FIG. 5, accordingly, the hook 4 and the hooked member 5 have punched cross-sectional surfaces that can form internal protrusions at the respective edges E1 to E3 in the cover width direction (the left-right direction in the drawing). Therefore, in order to configure the respective edges E1 to E3 that can form these internal protrusions to satisfy the requirements of the internal protrusions, a felt covering member 6 that can cover the respective edges E1 to E3 with a thick layer is sewn to the bottom cover piece 3 that covers them from the outside.

[0025] As shown in Fig. 4, the engaging tool 4 is formed of a horizontally long plate-shaped member with a reverse J-shaped cross section. Specifically, the engaging tool 4 has a flat plate-shaped base portion 4A that extends straight in the height direction, and a curved plate-shaped hook portion 4B that extends so as to be bent backward and upward from the lower end shown in the figure of the base portion 4A to the outer surface side of the cover, and has a reverse J-shaped cross-sectional plate shape.

[0026] The engaging tool 4 is stitched so that its base portion 4A extends in the cover width direction along the lower cover terminal 2A of the back cover piece 2 (stitching portion S1). Specifically, the engaging tool 4 has the rear surface shown in the figure of its base portion 4A applied to the inner surface of the cover of the back cover piece 2 and is stitched along the cover terminal 2A. Thereby, the engaging tool 4 is in an attached state where the hook portion 4B extends so as to be bent backward and upward from the cover terminal 2A of the back cover piece 2.

[0027] A return 4C that protrudes claw-like toward the base portion 4A is formed at the end of the bent tip of the hook portion 4B. The engaging tool 4 is shaped to extend with a constant cross section in the cover width direction. As shown in Fig. 2, the engaging tool 4 is stitched so as to continuously extend in the cover width direction over substantially the entire area excluding both ends in the cover width direction of the back cover piece 2.

[0028] As shown in Figs. 4 and 6, the engaged tool 5 is formed of a flat plate-shaped member that extends with a uniform cross-sectional shape in the cover width direction. The engaged tool 5 is stitched so as to extend in the cover width direction along the upper cover terminal 3A of the lower cover piece 3 (stitching portion S2).

[0029] As shown in Fig. 4, specifically, the engaged tool 5 has the rear surface shown in the figure applied to the inner surface of the cover of the lower cover piece 3, and its tip is stitched along the cover terminal 3A. Thereby, the engaged tool 5 is in an attached state where it extends in the cover width direction on the inner surface of the cover along the cover terminal 3A of the lower cover piece 3.

[0030] The engaged fitting 5 is inserted into and fixed to the engaging fitting 4 according to the following procedure. First, the lower surface cover piece 3 is pulled upward, and while the engaged fitting 5 is inverted forward, it is inserted between the base 4A and the hook portion 4B of the engaging fitting 4 from the tip side (the side of the stitching portion S2 stitched to the cover terminal 3A).

[0031] Thereby, as shown in FIG. 3, the engaged fitting 5, together with the cover terminal 3A stitched to its tip, is inserted between the base 4A and the hook portion 4B of the engaging fitting 4. Then, the insertion force applied to the engaged fitting 5 is removed. Thereby, the engaged fitting 5 is tilted and locked so as to be applied to both the base 4A and the hook portion 4B of the engaging fitting 4 by the action of the tension against the pulling-in of the lower surface cover piece 3.

[0032] Specifically, after the above insertion and removal of the load, the engaged fitting 5 has a return 5A that protrudes claw-like from the middle of the surface facing the hook portion 4B, and the return 5A is hooked on the return 4C of the hook portion 4B. Thereby, the engaged fitting 5 is locked in a state where it is prevented from coming off the engaging fitting 4. As a result, the cover terminal 3A of the lower surface cover piece 3 is fixed in a state of being pulled along the cover terminal 2A of the back cover piece 2.

[0033] By inserting the engaged fitting 5 into the engaging fitting 4 with the above-mentioned inversion, the lower surface cover piece 3 has the surface portion that contacts the engaged fitting 5 bent back to the inner surface side of the cover with the contact surface with the engaged fitting 5 as a fulcrum (the bent-back surface portion 3B). Due to this bending-back, the action of the tension applied from the lower surface cover piece 3 to the engaged fitting 5 acts as a force to hook the return 5A of the engaged fitting 5 on the return 4C of the engaging fitting 4 from below in the drawing, and also acts as a force to tilt the engaged fitting 5 so as to press it against the base 4A with the contact surface with the hook portion 4B as a fulcrum.

[0034] Therefore, by these actions, the hooked member 5 can be fixed in a state of being hooked on the hooking member 4. At the upper end shown in the figure, which is the proximal end of the hooked member 5, a ball edge 5B is formed to guide the bending of the bent surface portion 3B of the lower surface cover piece 3 so as to be a curved bending without the edge standing up. By the guidance of this ball edge 5B, the bent surface portion 3B of the lower surface cover piece 3 is bent without causing scratches due to rubbing against the hooked member 5.

[0035] As shown in FIG. 6, the hooked member 5 is stitched so as to continuously extend in the cover width direction over substantially the entire area except for both ends in the cover width direction of the lower surface cover piece 3. The covering members 6 are provided at two positions near both ends in the cover width direction of the lower surface cover piece 3. Each covering member 6 is made of a felt material cut into a rectangular shape.

[0036] Each covering member 6 is set and stitched so that their upper edges shown in the figure are joined along the upper cover terminal 3A of the lower surface cover piece 3. Specifically, each covering member 6 is provided at positions where both ends of the hooked member 5 are located on the inner surface of the cover of the lower surface cover piece 3. That is, each covering member 6 is not provided at a position corresponding to the center in the cover width direction of the hooked member 5, but is provided only at positions corresponding to both ends.

[0037] Each covering member 6 is set on the inner surface of the cover before the hooked member 5 is stitched to the inner surface of the lower surface cover piece 3. Then, after each covering member 6 is set, the hooked member 5 is set so as to be bridged between the inner surfaces of each covering member 6, and the hooked member 5 is stitched to the lower surface cover piece 3 together with each covering member 6.

[0038] Specifically, each covering member 6 and the hooked member 5 are stitched so that their upper edges shown in the figure have a sewing line extending in the cover width direction along the cover terminal 3A of the lower surface cover piece 3 (sewing portion S2). By this stitching, the hooked member 5 is provided such that each edge E3 in its cover width direction (left - right direction shown in the figure) is covered from the outer side of the cover by each covering member 6.

[0039] Each covering member 6 extends from a position inside the cover width direction than each edge E3 of the hooking member 5 to a position protruding outward. Further, each covering member 6 extends from a position aligned with the upper edge in the drawing of the hooking member 5 to a position protruding downward in the drawing.

[0040] In other words, each covering member 6 is provided such that the region on the upper corner side inside the cover width direction thereof overlaps the hooking member 5 in the in-plane arrangement, and other portions extend outward in the cover width direction or downward in the drawing from the hooking member 5. As shown in FIG. 3, thereby, when the hooking member 5 is inserted into the hooking tool 4 with inversion, each covering member 6 is bent along the inner peripheral surface of the cover of the bent surface portion 3B of the lower surface cover piece 3.

[0041] And by this bending, a first covering portion 6A that extends so as to be bent backward and downward with the ball edge 5B of the hooking member 5 as a fulcrum of each covering member 6 covers each edge E1 of the hook portion 4B of the hooking tool 4, each edge E3 of the hooking member 5, and each edge E2 of the base portion 4A of the hooking tool 4 from the rear side (cover outer surface side) in the drawing as shown in FIG. 5. As shown in FIG. 3, the first covering portion 6A is shaped to extend to a position beyond the hook portion 4B of the hooking tool 4 downward in the drawing.

[0042] Furthermore, each covering member 6 is in a state where a second covering portion 6B extending from the lower edge stitched to the tip (lower end in the drawing) of the hooking member 5 to the ball edge 5B covers each edge E2 of the base portion 4A of the hooking tool 4 from the rear side (cover outer surface side) in the drawing as shown in FIG. 5.

[0043] Here, the hooking member 5 is longer in the cover width direction than the hooking tool 4. And the hooking member 5 is configured to be hooked such that both ends in the cover width direction thereof protrude outward in the cover width direction from the hooking tool 4.

[0044] Accordingly, each covering member 6 is also provided so as to project outward from both ends in the cover width direction of the engaging tool 4 by engaging the engaged tool 5 with the engaging tool 4. As a result, each covering member 6 can appropriately cover each of the above-mentioned edges E1 to E3 from the rear side (cover outer surface side) in the drawing.

[0045] As shown in FIG. 3, since each covering member 6 is stitched to the tip (lower end in the drawing) of the engaged tool 5 inserted into the engaging tool 4, the stitching portion (stitching portion S2) thereof is covered by the hook portion 4B and is less likely to be exposed to the outside. Therefore, the appearance of the seat cover 1 is less likely to be spoiled.

[0046] The second covering portion 6B of each covering member 6 extends from the tip (lower end in the drawing) of the insertion region 3C where the engaged tool 5 is inserted into the engaging tool 4 to the bead edge 5B that crosses the hook portion 4B upward in the drawing. Therefore, the second covering portion 6B of each covering member 6 can appropriately cover each edge E2 (see FIG. 5) of the base portion 4A of the engaging tool 4 over a wide range in the height direction.

[0047] Summarizing the above, the seat cover 1 according to the present embodiment is configured as follows. The reference numerals in parentheses below correspond to the respective configurations shown in the above embodiment.

[0048] That is, the seat cover (1) is a seat cover (1) having one cover terminal (2A) and the other cover terminal (3A) that are attracted to and fixed to each other. The seat cover (1) includes an engaging tool (4), an engaged tool (5), and a covering member (6). The engaging tool (4) has a base portion (4A) stitched so as to extend in the cover width direction along one cover terminal (2A), and a hook portion (4B) extending so as to be bent back to the cover outer surface side from the tip in the retracting direction of the base portion (4A).

[0049] The engaged member (5) is stitched so as to extend in the cover width direction along the inner surface side of the cover along the other cover terminal (3A). The engaged member (5) is inserted between the base portion (4A) and the hooked portion (4B) of the hooking member (4) with inversion so as to bend back the other cover portion (3) including the other cover terminal (3A) to the inner surface side of the cover. Thus, the hooked portion (4B) is hooked against the tension caused by the pulling-in of the other cover terminal (3A).

[0050] The covering member (6) is stitched to the other cover portion (3). The covering member (6) has a first covering portion (6A) that extends so as to cover, from the outer surface side of the cover, each edge (E1 to E3) on one side in the cover width direction of the hooked portion (4B), the base portion (4A) of the hooking member (4), and the engaged member (5) along the inner peripheral surface of the cover of the bent-back surface portion (3B) of the other cover portion (3).

[0051] According to the above configuration, the covering member (6) provided only on the other cover portion (3) can appropriately cover each edge (E1 to E3) on one side in the sheet width direction of the hooking member (4) and the engaged member (5) from the outer surface side of the cover.

[0052] Further, the covering member (6) further has a second covering portion (6B) that extends so as to cover the edge (E2) of the base portion (4A) from the outer surface side of the cover along the insertion region (3C) inserted between the base portion (4A) and the hooked portion (4B) of the bent-back surface portion (3B) from the first covering portion (6A). According to the above configuration, the edge (E2) of the base portion (4A) of the hooking member (4) can be covered by both the first covering portion (6A) and the second covering portion (6B).

[0053] Also, the other cover terminal (3A) is stitched along the tip in the insertion direction of the engaging member (5) together with the second covering portion (6B). According to the above configuration, the second covering portion (6B) can be provided so as to widely cover the edge (E2) of the base portion (4A) of the engaging member (4) from the tip side in the insertion direction. Further, the covering member (6) and the engaged member (5) can be stitched with reference to the edge of the other cover terminal (3A). Furthermore, since these stitching portions (stitching portion S2) are located at the tip of the engaged member (5) inserted between the base portion (4A) and the hook portion (4B) of the engaging member (4), it is possible to make it difficult for the stitching portions (stitching portion S2) to be exposed to the outside.

[0054] Also, the first covering portion (6A) protrudes in one direction in the cover width direction from the engaged member (5). The engaged member (5) protrudes in one direction in the cover width direction from the engaging member (4). According to the above configuration, since the first covering portion (6A) is configured to protrude further in one direction in the cover width direction than the engaged member (5) that protrudes in one direction in the cover width direction from the engaging member (4), it is possible to more reliably cover the respective edges (E1 to E3) of the engaging member (4) and the engaged member (5) from the cover outer surface side.

[0055] Also, the covering member (6) is provided separately on both sides excluding the central portion in the cover width direction of the other cover portion (3) so as to cover the hook portion (4B), the base portion (4A) of the engaging member (4), and the respective edges (E1 to E3) on one side and the respective edges (E1 to E3) on the other side in the cover width direction of the engaged member (5) from the cover outer surface side. According to the above configuration, while appropriately covering the respective edges (E1 to E3) of the engaging member (4) and the engaged member (5) with the covering member (6), it is possible to appropriately suppress the increase in size of the covering member (6).
