Description

[Technical Field]

[0001] The present invention relates to a vehicle seat, and more particularly to a trim cover. [Background technology]

[0002] The vehicle seatback disclosed in Patent Document 1 below includes a seatback frame having a pluma (spring mat) for elastically supporting the back of an occupant, a seatback main body having a seatback pad that covers the seatback frame, and a bag-shaped seat covering (trim cover) that covers the surface of the seatback main body. The trim cover has first and second hanging portions (pulling members), and hooks (fastening devices) attached to the tip of each hanging portion are fastened to the spring mat. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] No. No. 3196872 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned prior art, for example, when a part of the seat back frame is positioned around the pull-out material of the trim cover inside the seat back, there is little space to fasten the fastening device attached to the tip of the pull-out material to an internal structure such as a spring mat, making it difficult to work.

[0005] An object of the present invention is to provide a trim cover that makes it easy to fasten a fastening device attached to the tip of a pull member to an internal structure of the vehicle seat, and a vehicle seat equipped with the trim cover. [Means for solving the problem]

[0006] The trim cover of the first embodiment comprises a cover body that is placed over the seat pad of a vehicle seat, and a pull-out member that extends from the cover body to the inside of the vehicle seat and is formed in a bag shape that opens toward the outside of the vehicle seat, with a fastening device attached to the tip that is fastened to the internal structure of the vehicle seat.

[0007] In the trim cover of the first aspect, a pull-up member extends from a cover main body that covers the seat pad of the vehicle seat toward the inside of the vehicle seat. The pull-up member is formed in a bag shape that opens toward the outside of the vehicle seat, and a fastening device attached to the tip is fastened to an internal structure of the vehicle seat. When fastening this fastening device to an internal structure of the vehicle seat, a finger can be inserted inside the bag-shaped pull-up member from the outside of the vehicle seat and hooked onto the pull-up member, making it easy to fasten the fastening device.

[0008] In the second aspect of the trim cover, in the first aspect, the seat pad is a seat back pad, the pull member extends from the portion of the cover body that covers the back of the seat back pad, and the fastening device is fastened to the internal structure of the seat back.

[0009] In the second embodiment, the trim cover is placed over the seatback pad, and a pull-out member extends from the portion covering the back of the seatback pad, with a fastener attached to the tip of the pull-out member fastening to the internal structure of the seatback. While a portion of the seatback frame may be located inside the seatback on the back side of the seatback, making space narrow, this embodiment allows a finger or the like to be inserted inside the bag-shaped pull-out member, making it easy to fasten the fastener.

[0010] In a trim cover of a third aspect, in the first or second aspect, the internal structure is an insert wire embedded in the seat pad.

[0011] In the trim cover of the third embodiment, a fastener attached to the tip of the pull-out material is fastened to an insert wire embedded in the seat pad. Although a spring mat is placed on the back side of the seat back pad, which can sometimes make space narrow, this embodiment allows a finger or other object to be inserted inside the bag-shaped pull-out material, making it easy to fasten the fastener.

[0012] The vehicle seat of the fourth aspect comprises a seat frame which is a skeletal member, a seat pad attached to the seat frame, and a trim cover of any one of the first to third aspects in which the cover body is placed over the seat pad.

[0013] In the vehicle seat of the fourth aspect, the cover body of the trim cover is placed over the seat pad attached to the seat frame, which is a framework member. This trim cover is any one of the first to third aspects, and therefore the above-mentioned effects can be obtained. [Effects of the Invention]

[0014] As described above, the trim cover and vehicle seat according to the present invention facilitate the task of fastening the fastener attached to the tip of the pull member to the internal structure of the vehicle seat. [Brief explanation of the drawings]

[0016] First Embodiment A trim cover 30 according to a first embodiment of the present invention will be described below with reference to Figures 1 to 3. Note that in each figure, some reference numerals may be omitted to make the drawings easier to see. Furthermore, the arrows FR and UP shown in Figures 1 and 2 indicate the front and top of a vehicle seat 10 equipped with the trim cover 30 according to this embodiment. Hereinafter, when the front-rear, left-right, top-bottom directions are used in the description, they will indicate directions relative to the vehicle seat 10.

[0017] 1, a vehicle seat 10 includes a seat cushion 12 on which a 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 floor of the vehicle via a slide mechanism 18.

[0018] 1 and 2, the seat back 14 has a seat back frame 20 which is a framework member, a seat back pad 22 which is a cushioning material attached to the seat back frame 20, a spring mat 26 which is an elastic member attached to the seat back frame 20, and a trim cover 30 which is a surface covering the seat back pad 22. The seat back frame 20 corresponds to the "seat frame" in the present invention, and the seat back pad 22 corresponds to the "seat pad" in the present invention.

[0019] The seatback frame 20 is formed by combining, for example, press-formed metal plates and metal pipes. The seatback frame 20 includes an upper bracket 20A that extends in the left-right direction on the rear side of the upper part of the seatback 14. The upper bracket 20A is formed from press-formed metal plates and is disposed with its thickness direction aligned approximately in the front-to-rear direction.

[0020] The seatback pad 22 is made of a foam such as urethane foam, and covers the seatback frame 20 from above and from the front. The upper part of the seatback pad 22 faces the upper bracket 20A from the front side with a gap therebetween. An insert wire 24 is embedded in the rear side of the upper part of the seatback pad 22. This insert wire 24 is, for example, foamed integrally with the seatback pad 22, and extends in the left-right direction. This insert wire 24 faces the lower end of the upper bracket 20A from the front side with a gap therebetween. This insert wire 24 corresponds to the "internal structure" in this invention.

[0021] The spring mat 26 is made of, for example, a bent metal wire and is disposed on the rear side of the seat back pad 22. For example, both vertical ends of the spring mat 26 are engaged with the seat back frame 20, and the spring mat 26 elastically supports the seat back pad 22 from the rear side. The spring mat 26 is configured to include a spring portion 26A disposed slightly below the upper bracket 20A and the insert wire 24.

[0022] The trim cover 30 includes a cover body 32 that covers the seat back pad 22, a pull material (pull cloth) 36 attached to the cover body 32, and a J hook 38 attached to the pull material 36. The J hook 38 corresponds to the "fastening device" in this invention. The cover body 32 is configured into a bag shape by sewing together multiple sheets of cover material made of cloth, leather, or synthetic leather, and is placed over the seat back pad 22 from above. The cover body 32 has a front cover material 32A that covers the front surface of the seat back pad 22 and a back cover material 32B that covers the back surface of the seat back pad 22. The upper bracket 20A and the spring mat 26 described above are arranged between the seat back pad 22 and the back cover material 32B.

[0023] A pull-up material 36 extends from the back surface material 32B toward the inside of the seat back 14. The pull-up material 36 is made of a long cloth material such as nonwoven fabric, and is arranged with its longitudinal direction in the left-right direction. The pull-up material 36 is arranged near the lower side of the upper bracket 20A. The cloth material that makes up the pull-up material 36 is folded in half in the width direction, and the pull-up material 36 is bag-shaped (generally V-shaped with an opening on the rear side) when viewed from the left-right direction, and is open toward the outside of the seat back 14.

[0024] Both widthwise ends of the fabric material constituting the pull member 36 are sewn to the back cover material 32B at seams S1 and S2 shown in FIG. 2. A slit 34 is formed in the back cover material 32B at a location facing the pull member 36. This slit 34 extends in the left-right direction. The internal space of the pull member 36 communicates with the space behind the seat back 14 through this slit 34. In other words, the bag-shaped pull member 36 opens to the outside of the seat back 14 through the slit 34. The slit 34 is configured to be closed by a closing member (e.g., a slide fastener, a Velcro fastener (registered trademark), etc.) (not shown) attached to the back cover material 32B.

[0025] The pull member 36 extends forward through the gap between the upper bracket 20A and the spring portion 26A. A fold is formed at the front end (tip) of the pull member 36, where the fabric material constituting the pull member 36 is folded in half. A J hook 38 is attached to the tip of the pull member 36. The J hook 38 is formed into an elongated shape by, for example, extrusion molding of resin, and is disposed with its longitudinal axis in the left-right direction. The J hook 38 is J-shaped when viewed from the left-right direction, and is fixed to the front end of the pull member 36 at the stitching portion S3. The pull member 36 is hooked onto and engaged with the insert wire 24. This allows the back cover material 32B to be pulled into the seat back pad 22 via the pull member 36 and the J hook 38.

[0026] In the vehicle seat 10 configured as described above, the cover body 32 of the trim cover 30 is placed over the seat back pad 22 attached to the seat back frame 20. In this trim cover 30, a pull member 36 extends from the back surface material 32B of the cover body 32 toward the inside of the seat back 14. The pull member 36 is formed in a bag shape that opens toward the outside (here, the rear side) of the seat back 14, and a J hook 38 attached to the tip thereof is engaged with the insert wire 24, which is an internal structure of the seat back 14.

[0027] 3, when engaging the J hook 38 with the insert wire 24, a finger F can be inserted into the inside of the bag-shaped pull member 36 from the outside of the seat back 14 through the slit 34, and the pull member 36 can be hooked onto the finger F. In this case, by pushing the pull member 36 diagonally upward and forward with the finger F, the J hook 38 can be hooked onto the insert wire 24, making the operation of engaging the J hook 38 easier.

[0028] The above-described effects will be further explained using a comparative example shown in Figures 4 and 5. In this comparative example, the fabric material constituting the pull member 40 is not folded in half, and the pull member 40 is not formed in a bag shape. In order to hook the J hook 38 attached to the tip of the pull member 40 onto the insert wire 24, it is necessary to grasp the J hook 38 with fingers F, as shown in Figure 5. However, because the upper bracket 20A and the like get in the way and the working space is narrow, it is difficult to grasp the J hook 38 with fingers F, making the operation of engaging the J hook 38 complicated; however, this problem can be solved in this embodiment.

[0029] In particular, at the back of the seat back 14, it is necessary to pull the rear surface material 32B of the trim cover 30 forward to ensure legroom for rear seat passengers, but the upper bracket 20A and other components are arranged inside the seat back 14 on the rear side of the seat back 14, making the working space narrow. However, in this embodiment, the finger F can be inserted inside the bag-shaped pulling member 36, making it easier to engage the J hook 38. As a result, the degree of freedom in the arrangement of the upper bracket 20A and other components is improved.

[0030] In this embodiment, a J hook 38 attached to the tip of the pull member 36 is engaged with an insert wire 24 embedded in the seat back pad 22. The spring mat 26 is disposed on the back side of the seat back pad 22, narrowing the space for the J hook 38 engagement operation. However, in this embodiment, the bag-shaped pull member 36 can improve the workability of the J hook 38 engagement operation.

[0031] <Second embodiment> Next, a second embodiment of the present invention will be described. The same components and functions as those of the first embodiment are designated by the same reference numerals as those of the first embodiment, and the description thereof will be omitted. As shown in Figures 6 and 7, in this embodiment, the rear surface material 32B of the trim cover 30 is provided with a stitching portion S4 extending in the left-right direction instead of the slit 34.

[0032] As shown in FIG. 6, the rear edge of the upper portion 36A of the folded pull-up material 36 is sewn to the seam S4 on both the left and right sides and the left and right central portions of the seat back 14, and the pull-up material 36 opens toward the rear of the seat back 14. As shown in FIG. 7, the rear edges of the upper portion 36A and the lower portion 36B of the pull-up material 36 are sewn to the seam S4 on both the left and right sides and the left and right central portions of the seat back 14. The upper portion 36A and the lower portion 36B may be sewn to each other at locations other than the rear edge, but at least a portion of the pull-up material 36 must be open toward the rear of the seat back 14. Slits (not shown) extending in the up-down direction of the seat back 14 are formed on both the left and right sides of the seat back 14. These slits are configured to be closed by closing members (e.g., slide fasteners, hook-and-loop fasteners, etc.) attached to the back cover material 32B.

[0033] When engaging the J hook 38 with the insert wire 24, as shown in FIG. 8 , a finger F can be inserted from the outside of the seat back 14 into the inside of the bag-shaped pull member 36 through the slit and the pull member 36 can be hooked onto the finger F. In this case, the pull member 36 can be pushed diagonally upward and forward with the finger F to hook the J hook 38 with the insert wire 24. Once the engagement of the J hook 38 is complete, the slit is closed by a closing member attached to the back cover material 32B. As with the first embodiment, the engagement of the J hook 38 is also facilitated in this embodiment.

[0034] In the above-described embodiments, the J hook 38 is configured to be engaged with the insert wire 24 embedded in the seat back pad 22, but this is not limiting and the J hook 38 may be configured to be engaged with the spring mat 26. In this case, the spring mat 26 is the "internal structure" of the present invention.

[0035] Furthermore, in each of the above embodiments, the present invention has been described as being applied to the trim cover 30 of the seat back 14, but this is not limited thereto, and the present invention may also be applied to the trim cover of the seat cushion 12.

[0036] In addition, the present invention can be implemented in various modifications without departing from the spirit and scope of the present invention. Furthermore, it goes without saying that the scope of the present invention is not limited to the above-described embodiments. [Explanation of symbols]
