Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above prior art, when inserting the tip of the first hook portion of the first fastener member into the second hook portion of the second fastener member, it is a groping operation, so there is room for improvement from the viewpoint of improving workability.

[0005] An object of the present invention is to obtain a fastener for a trim cover and a trim cover that facilitate the operation of temporarily holding a second fastener member by a first fastener member.

Means for Solving the Problems

[0006] The fastener for the trim cover in the first embodiment comprises a plate-shaped first fastening portion fixed to the edge of the first surface material, and a first hook portion extending from one end of the first fastening portion in the width direction to one side in the thickness direction of the first fastening portion and extending to the other side in the width direction of the first fastening portion, with a first claw portion formed on the portion of the first fastening portion facing the tip of the first hook portion, and a plate-shaped second fastening portion fixed to the edge of the second surface material, a bent portion that is substantially crank-shaped in the middle of the width direction of the second fastening portion, and the width of the second fastening portion The device comprises a second fastening member having a second hook portion that protrudes from one end of the second fixing portion toward one side in the thickness direction, and which is inserted between the first fixing portion and the first hook portion so that the bent portion catches on the first claw portion and is fixed to the first fastening member, wherein the second fastening member is slid toward one side in the width direction of the first fixing portion with the second hook portion abutting against the surface of the first fixing portion toward one side in the thickness direction, so that the tip of the first hook portion is inserted into the second hook portion and temporarily held by the first fastening member.

[0007] According to the first embodiment of the trim cover fastener, the first fastening member has a plate-shaped first fixing portion fixed to the edge of the first surface material, and a first hook portion extending from one end of the first fixing portion in the width direction to one side in the thickness direction of the first fixing portion and extending to the other side in the width direction of the first fixing portion. A first claw portion is formed in the portion of the first fixing portion that faces the tip of the first hook portion. The second fastening member has a plate-shaped second fixing portion fixed to the edge of the second surface material, a bent portion that is bent in a substantially crank shape in the middle of the second fixing portion in the width direction, and a second hook portion that protrudes from one end of the second fixing portion in the width direction to one side in the thickness direction of the second fixing portion.

[0008] The second fastening member described above is inserted between the first fixing portion and the first hook portion of the first fastening member, and is fixed to the first fastening member by the bending portion catching on the first claw portion. Furthermore, the second fastening member is temporarily held in place by the first fastening member when the second hook portion is slid toward one side in the width direction of the first fixing portion of the first fastening member with the second hook portion abutting against one side of the first fixing portion in the thickness direction, so that the tip of the first hook portion is inserted into the second hook portion. In other words, the insertion is guided by the sliding of the second hook portion relative to the first fixing portion, making it easier to temporarily hold the second fastening member in place by the first fastening member.

[0009] In the second embodiment of the trim cover fastener, the tip of the first hook portion is bent diagonally toward the other side in the thickness direction and the other side in the width direction of the first fixing portion, and when the second fastening member is temporarily held by the first fastening member, the two surfaces formed on the tip of the first hook portion contact the second fastening member.

[0010] According to the trim cover fastener of the second embodiment, when the second fastening member is temporarily held by the first fastening member, the two surfaces formed at the tip of the first hook portion come into contact with the second fastening member, thereby stabilizing the temporary holding of the second fastening member with respect to the first fastening member.

[0011] In the third embodiment of the trim cover fastener, when the second fastening member is temporarily held by the first fastening member, the tip of the second hook portion fits between the tip of the first hook portion and the first claw portion, thereby restricting the displacement of the second fastening member relative to the first fastening member in the other direction in the width direction of the first fixing portion.

[0012] According to the trim cover fastener of the third embodiment, when the second fastening member is temporarily held by the first fastening member, the tip of the second hook portion fits between the tip of the first hook portion and one claw portion of the first hook portion. This restricts the displacement of the second fastening member relative to the first fastening member in the other direction in the width direction of the first fixing portion, thereby preventing the temporary holding state from being unintentionally released.

[0013] In the fourth embodiment of the trim cover fastener, when the second fastening member is fixed to the first fastening member in any one of the first to third embodiments, the second fastening member is elastically sandwiched between the first fixing portion and the first hook portion.

[0014] According to the trim cover fastener of the fourth embodiment, when the second fastening member is fixed to the first fastening member, the second fastening member is elastically sandwiched between the first fixing portion and the first hook portion of the first fastening member, thereby preventing the second fastening member from rattling relative to the first fastening member.

[0015] The trim cover of the fifth embodiment comprises a cover body having a first surface material and a second surface material, and a trim cover fastener of any one of the first to fourth embodiments, wherein the first fixing portion of the first fastening member is fixed to the edge of the first surface material, and the second fixing portion of the second fastening member is fixed to the edge of the second surface material.

[0016] In the trim cover of the fifth embodiment, the first fixing portion of the first fastening member of the fastener is fixed to the edge of the first surface material of the cover body. The second fixing portion of the second fastening member of the fastener is fixed to the edge of the second surface material of the cover body. Since this fastener is of any one embodiment from the first to fourth embodiments, the effects described above are obtained. [Effects of the Invention]

Mode for Carrying Out the Invention

[0019] Hereinafter, a trim cover 30 according to one embodiment of the present invention will be described with reference to Figures 1 to 13. In each figure, some reference numerals may be omitted for the sake of clarity. Also, the arrows FR and UP shown in Figures 1 and 2 indicate the front and above the vehicle seat 10 equipped with the trim cover 30 according to this embodiment. Hereafter, when simply referring to the front, rear, left, right, up, and down directions, these directions will be in relation to the vehicle seat 10.

[0020] As shown in Figure 1, the vehicle seat 10 includes a seat cushion 12 on which the vehicle occupant sits, a seat back 14 that supports the occupant's back, and a headrest 16 that supports the occupant's head. The seat cushion 12 is connected to the vehicle floor via a sliding mechanism 18.

[0021] As shown in Figures 1 and 2, the seat back 14 includes a seat back frame (not shown), which is a skeletal member; a seat back pad 20, which is a cushioning material attached to the seat back frame; and a trim cover 30, which is a surface covering the seat back pad 20.

[0022] The seat back frame is constructed by combining, for example, press-formed metal plates or metal pipes. The lower end of the seat back frame is reclinedly connected to the rear end of a seat cushion frame (not shown), which is a skeletal member of the seat cushion 12, via a well-known reclining mechanism 22. This reclining mechanism 22 includes a reclining rod 24 located at the lower end of the seat back 14. The reclining rod 24 is made of, for example, a metal pipe and is oriented with its axis in the left-right direction.

[0023] The seat back pad 20 is made of a foam material such as urethane foam and is placed over the seat back frame from above and in front. A slit 26 is formed at the lower end of the seat back pad 20, which opens toward the rear and extends in the left-right direction. The reclining rod 24 is housed in this slit 26.

[0024] The trim cover 30 comprises a cover body 32 formed in a bag shape by sewing together multiple surface materials made of cloth, leather, or synthetic leather, and fasteners 34 attached to the cover body 32. The cover body 32 is placed over the seat back pad 20 from above. The cover body 32 has a front surface material 32A that covers the front of the seat back pad 20 and a back surface material 32B that covers the back of the seat back pad 20. The back surface material 32B corresponds to the "first surface material" in this invention, and the front surface material 32A corresponds to the "second surface material" in this invention.

[0025] The lower end of the front surface material 32A is wrapped around the lower end of the seat back pad 20 from below. The lower edge of the front surface material 32A is positioned on the back side of the seat back 14. The lower edge of the front surface material 32A and the lower edge of the back surface material 32B are fastened together using fasteners 34.

[0026] As shown in Figures 3 to 13, the fastener 34 is composed of a first fastening member, a J-hook 36, and a second fastening member, an arrow 38. Note that the front surface material 32A is not shown in Figures 4, 6 to 8, and 10 to 13. The arrow 38 is fitted inside the J-hook 36. The J-hook 36 is manufactured, for example, by resin extrusion molding and has a long shape with its longitudinal side in the left-right direction. This J-hook 36 has a plate-shaped first fixing part 36A and a first hook part 36B extending from one end (in this case, the lower end) in the width direction of the first fixing part 36A, and has a roughly J-shape when viewed from the left-right direction.

[0027] The first fixing portion 36A is positioned with its front-to-back direction as the thickness direction. At the other end of the first fixing portion 36A in the width direction (in this case, the upper end), the lower edge of the back surface material 32B is folded in half and superimposed on the surface of the first fixing portion 36A on one side in the thickness direction (in this case, the rear side). The folded portion of the lower edge of the back surface material 32B is fixed (sewn in this case) to the first fixing portion 36A at the sewing portion T1.

[0028] The first hook portion 36B extends from the lower end of the first fixing portion 36A toward the rear (i.e., one side in the thickness direction of the first fixing portion 36A) and also extends toward the upper (i.e., the other side in the width direction of the first fixing portion 36A). The tip of the first hook portion 36B is positioned at a distance from the rear of the upper and lower middle portion of the first fixing portion 36A. The tip (upper end) of the first hook portion 36B is bent diagonally toward the front and upward (i.e., the other side in the thickness direction and the other side in the width direction of the first fixing portion 36A).

[0029] A first claw portion 36C is formed in the first fixing portion 36A at the portion facing the tip of the first hook portion 36B. The first claw portion 36C protrudes in a stepped manner from the rear surface of the upper-middle portion of the first fixing portion 36A toward the rear, and the upper-middle portion of the first fixing portion 36A where the first claw portion 36C is formed is bent in a roughly crank shape. The rear surface of the first fixing portion 36A is positioned such that the portion above the first claw portion 36C is offset toward the rear relative to the portion below the first claw portion 36C. An opening 40 is formed between the first claw portion 36C and the tip of the first hook portion 36B.

[0030] The arrow 38 is manufactured, for example, by resin extrusion molding and has a long shape with its length in the left-right direction. The arrow 38 has a plate-shaped second fixing portion 38A, a bent portion 38C which is bent in a roughly crank shape in the middle of the width direction (middle of the vertical direction) of the second fixing portion 38A, and a second hook portion 38B which protrudes from one end of the second fixing portion 38A in the width direction (in this case, the lower end) to one side of the second fixing portion 38A in the thickness direction (in this case, the rear side).

[0031] The second fixing portion 38A is positioned with its front-to-back direction as the thickness direction. On the other side of the second fixing portion 38A in the width direction (in this case, the upper part), the lower edge of the front surface material 32A is overlapped with the other side of the second fixing portion 38A in the thickness direction (in this case, the front side). The lower edge of the front surface material 32A is wrapped around the upper part of the second fixing portion from the rear and above, and is fixed (sewn in this case) to the second fixing portion 38A at the sewing portion T2. ​​The second hook portion 38B extends from the lower end of the second fixing portion 38A toward the rear (i.e., one side of the second fixing portion 38A in the thickness direction), and its tip is bent toward the upward side (i.e., the other side of the second fixing portion 38A in the width direction).

[0032] A bent portion 38C is formed in the middle of the second fixing portion 38A in the width direction, and is bent in a roughly crank shape toward the other side in the thickness direction of the second fixing portion 38A. The portion of the second fixing portion 38A above the bent portion 38C (the other side in the width direction) is offset to the rearward side relative to the portion below the bent portion 38C (one side in the width direction). A part of this bent portion 38C is designated as the second claw portion 38C1. The second claw portion 38C1 protrudes in a stepped manner forward from the front surface of the middle of the second fixing portion 38A in the vertical direction. The front surface of the second fixing portion 38A (i.e., the surface on the other side in the thickness direction) is positioned such that the portion above the second claw portion 38C1 is offset to the rearward side relative to the portion below the second claw portion 38C1.

[0033] In the above configuration, the arrow 38 has a portion below the second claw portion 38C1 that is inserted (fitted) between the first fixing portion 36A and the first hook portion 36B of the J-hook 36, and the second claw portion 38C1, which is part of the bent portion 38C, catches on the first claw portion 36C, thereby fixing (locking) it to the J-hook 36. The portion of this arrow 38 that is inserted between the first fixing portion 36A and the first hook portion 36B is elastically sandwiched between the first fixing portion 36A and the first hook portion 36B.

[0034] When the arrow 38 is inserted between the first fixing portion 36A and the first hook portion 36B of the J-hook 36, as shown in Figure 4, the second hook portion 38B of the arrow 38 abuts against one side of the first fixing portion 36A in the thickness direction (in this case, the rear surface) S1, and the arrow 38 slides toward one side of the first fixing portion 36A in the width direction (in this case, downward). As shown in Figure 5, the tip of the second hook portion 38B of the arrow 38 has an inclined surface S2 that abuts against the rear surface of the first fixing portion 36A when the arrow 38 slides as described above. This inclined surface S2 is inclined at, for example, 45 degrees with respect to the tip surface S3 of the second hook portion 38B. When this inclined surface S2 abuts against one side of the first fixing portion 36A in the thickness direction (S1), the arrow 38 slides at an angle of approximately 45 degrees relative to the J-hook 36. This configuration guides the insertion of the tip of the first hook portion 36B into the second hook portion 38B.

[0035] As shown in Figure 6, when the arrow 38 is slid upright at an angle greater than 45 degrees (for example, 60 degrees) relative to the J-hook 36, the tip of the second hook portion 38B comes into contact with the tip of the first hook portion 36B. As a result, the arrow 38 rotates around this contact point as a pivot, and is positioned in the temporary holding position shown by the dashed line in Figure 6. Also, as shown in Figure 7, when the arrow 38 is slid at an angle less than 45 degrees (for example, 30 degrees) relative to the J-hook 36, the second hook portion 38B comes into contact with the corner between the inclined surface S7 and the rearward-facing surface S8 of the first hook portion 36B, which will be described later. As a result, the arrow 38 rotates around this contact point as a pivot, and is positioned in the temporary holding position shown by the dashed line in Figure 7.

[0036] The tip surface S3 of the second hook portion 38B is on the same plane as the surface S4 on one side in the thickness direction of the portion of the second fixing portion 38A on the other side in the width direction. Furthermore, the tip surface S3 of the second hook portion 38B and the surface S5 on the other side in the thickness direction of the portion of the second fixing portion 38A on the other side in the width direction are arranged parallel to each other. The dimension W2 between the tip surface S3 of the second hook portion 38B and the surface S5 on the other side in the thickness direction of the portion of the second fixing portion 38A on the other side in the width direction is set to be the same as the dimension W1 between the first fixing portion 36A and the first hook portion 36B of the J-hook 36.

[0037] As described above, the arrow 38, which is slid relative to the J-hook 36, is configured to be temporarily held by the J-hook 36 by inserting the tip of the first hook portion 36B into the second hook portion 38B, as shown in Figure 8. The dimension W4 (see Figure 8) between the inner surface S6 (see Figure 5) and the inclined surface S2 of the second hook portion 38B is set to be slightly larger than the width dimension W3 (see Figure 8) of the opening 40 of the J-hook 36. Therefore, when the arrow 38 is temporarily held by the J-hook 36 (hereinafter sometimes simply referred to as the "temporarily held state"), the tip of the second hook portion 38B fits between the tip of the first hook portion 36B and the first claw portion 36C. As a result, in the temporarily held state, the arrow 38 is configured to restrict upward displacement relative to the J-hook 36.

[0038] As shown in Figure 9, the tip of the first hook portion 36B of the J-hook 36 has an inclined surface S7 facing approximately rearward and upward, and a rearward-facing surface S8 facing approximately rearward. The inclined surface S7 is inclined at, for example, 45 degrees with respect to the rearward-facing surface S8. Also, as shown in Figure 5, an inclined surface S9 is formed on the side of the bent portion 38C of the arrow 38 that is opposite to the second claw portion 38C1. This inclined surface S9 is formed parallel to the inclined surface S2 at the tip of the second hook portion 38B. When the tip of the first hook portion 36B is inserted into the second hook portion 38B and temporarily held by the J-hook 36, the inclined surface S9 of the bent portion 38C slides against the rearward-facing surface S8 of the first hook portion 36B, thereby guiding the insertion.

[0039] Furthermore, in the temporary holding state described above, the surface S10 (see Figure 5) on one side in the thickness direction of the second fixing portion 38A on one side in the width direction makes surface contact with the inclined surface S7 of the first hook portion 36B, and the inclined surface S9 of the bending portion 38C makes surface contact with the rearward-facing surface S8 of the first hook portion 36B. In other words, in the temporary holding state described above, the two surfaces (inclined surface S7 and rearward-facing surface S8) formed at the tip of the first hook portion 36B are configured to contact the arrow 38.

[0040] As shown in Figures 10 to 13, the arrow 38 is rotated from the temporary holding state described above around the tip of the first hook portion 36B relative to the J-hook 36 and inserted between the first fixing portion 36A and the first hook portion 36B. As shown in Figure 10, when the arrow 38 is positioned perpendicular to the J-hook 36, the width dimension W6 of the second hook portion 38B is larger than the width dimension W5 of the opening 40 of the J-hook 36 shown in Figure 10. This prevents the second hook portion 38B from slipping out from between the tip of the first hook portion 36B and the first claw portion 36C. Similarly, as shown in Figure 11, when the arrow 38 is tilted diagonally upward relative to the J-hook 36, the width dimension W8 of the second hook portion 38B is larger than the width dimension W7 of the opening 40 of the J-hook 36 shown in Figure 11. This configuration prevents the second hook portion 38B from slipping out from between the tip of the first hook portion 36B and the first claw portion 36C.

[0041] As shown in Figure 12, when the arrow 38 is inserted between the first fixing portion 36A and the first hook portion 36B of the J-hook 36, the J-hook 36 elastically deforms so that the opening 40 of the J-hook 36 widens. Then, the second claw portion 38C1 of the arrow 38 catches on the first claw portion 36C of the J-hook 36, causing the J-hook 36 to elastically return to its original position, and the bent portion 38C of the arrow 38 is elastically sandwiched between the tip of the first hook portion 36B and the first claw portion 36C. As a result, the arrow 38 is fixed to the J-hook 36.

[0042] In the trim cover 30 with the above configuration, the first fixing portion 36A of the J-hook 36 of the fastener 34 is fixed to the lower edge of the back surface material 32B of the cover body 32. The second fixing portion 38A of the arrow 38 of the fastener 34 is fixed to the lower edge of the front surface material 32A of the cover body 32. From one end of the first fixing portion 36A in the width direction, the first hook portion 36B extends to one side of the first fixing portion 36A in the thickness direction and also extends to the other side of the first fixing portion 36A in the width direction. A first claw portion 36C is formed in the portion of the first fixing portion 36A that faces the first hook portion 36B. A bent portion 38C that is bent in a roughly crank shape is provided in the middle of the second fixing portion 38A in the width direction of the arrow 38. From one end of the second fixing portion 38A in the width direction, the second hook portion 38B protrudes toward one side in the thickness direction of the second fixing portion 38A.

[0043] The arrow 38 described above is inserted between the first fixing portion 36A and the first hook portion 36B of the J-hook 36, and is fixed to the J-hook 36 by the bending portion 38C catching on the first claw portion 36C. Furthermore, the arrow 38 is temporarily held on the J-hook 36 by sliding the second hook portion 38B toward one side in the width direction of the first fixing portion 36A with the second hook portion 38B abutting against one side of the first fixing portion 36A of the J-hook 36, so that the tip of the first hook portion 36B is inserted into the second hook portion 38B. In other words, the insertion is guided by the sliding of the second hook portion 38B relative to the first fixing portion 36A, making it easier to temporarily hold the arrow 38 on the J-hook 36.

[0044] Furthermore, in this embodiment, the tip of the first hook portion 36B is bent diagonally toward the other side in the thickness direction and the other side in the width direction of the first fixing portion 36A, so that when the arrow 38 is temporarily held by the J-hook 36, the two surfaces (inclined surface S7 and rearward-facing surface S8) formed on the tip of the first hook portion 36B come into contact with the arrow 38. This stabilizes the temporary holding of the arrow 38 with respect to the J-hook 36.

[0045] Furthermore, in this embodiment, when the arrow 38 is temporarily held by the J-hook 36, the tip of the second hook portion 38B fits between the tip of the first hook portion 36B and the first claw portion 36C. This restricts the displacement of the arrow 38 relative to the J-hook 36 to the other side in the width direction of the first fixing portion 36A, thereby preventing the temporary holding state from being unintentionally released.

[0046] Furthermore, in this embodiment, when the arrow 38 is fixed to the J-hook 36, the arrow 38 is elastically sandwiched between the first fixing portion 36A and the first hook portion 36B, thereby preventing the arrow 38 from rattling relative to the J-hook 36.

[0047] In the above embodiment, the case in which the present invention is applied to the trim cover 30 of the seat back 14 was described, but the present invention is not limited to this and can also be applied to the trim cover of the seat cushion or headrest.

[0048] Furthermore, although the above embodiment described the case in which the present invention is applied to seats for vehicles, the present invention is also applicable to seats for vehicles other than vehicles (for example, aircraft and ships).

[0049] Furthermore, the present invention can be implemented with various modifications without departing from its spirit. Of course, the scope of the present invention is not limited to the embodiments described above. [Explanation of symbols]
