Description

[Technical Field]

[0001] The present invention relates to a seat. [Background technology]

[0002] A structure in which a trim cover is attached to a seat pad by assembling a plurality of clips provided on the trim cover to a wire integrally molded with the seat pad has been known for some time (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-008488 Summary of the Invention [Problem to be solved by the invention]

[0004] In a seat with such a configuration, when dismantling the seat to remove the trim cover from the seat pad, it is necessary to remove each of the clips from the wire. However, because the clips are designed to be difficult to remove from the wire, it may be difficult for the worker to remove them without tools, which could make the dismantling process cumbersome.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a seat that allows for easy disassembly work of removing the trim cover from the seat pad. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, a first aspect of the seat according to the present invention comprises a seat pad, a trim cover that covers the seat pad and has a clamped portion on its back side opposite to the front side of the seat pad, and a plurality of clips that are provided on the seat pad and clamp the clamped portion, wherein the clamped portion extends along the pulling direction when the trim cover is removed from the seat pad, and the plurality of clips are arranged in a line in the pulling direction.

[0007] According to the first aspect of the invention, the trim cover that covers the seat pad has a clamped portion on the back side opposite the front side of the seat pad, and the seat pad is provided with a plurality of clips that clamp the clamped portion. Here, the clamped portion extends along the pulling direction when the trim cover is removed from the seat pad, and the plurality of clips are arranged side by side in the pulling direction. Therefore, without having to remove the plurality of clips from the clamped portions one by one, it is possible to remove the clamped portions from the plurality of clips simply by pulling the trim cover in the pulling direction. This facilitates the disassembly work of removing the trim cover from the seat pad.

[0008] A sheet according to a second aspect of the present invention is the sheet according to the first aspect, wherein the plurality of clips are connected by a support member extending in the pulling-out direction.

[0009] According to the second aspect of the invention, the clips are connected by a support member that extends in the direction of removal when removing the trim cover from the seat pad. This makes it easy to attach the clips to the seat pad. Furthermore, during disassembly work to remove the trim cover from the seat pad, the clips are less likely to come off the seat pad, making it easier to remove the clamped portion from the clips.

[0010] In addition, a third aspect of the seat according to the present invention is a seat according to the first or second aspect, wherein the seat pad has a hole portion penetrating in the thickness direction, and the trim cover has a lock portion that is inserted into the hole portion from the front side of the seat pad and is locked on the back side of the seat pad to prevent it from coming out.

[0011] According to the third aspect of the invention, the seat pad has a hole penetrating through it in the thickness direction, and the locking portion of the trim cover is inserted into the hole from the front side of the seat pad and locked on the back side of the seat pad so as not to come off. Therefore, when dismantling the seat pad to remove the trim cover, it is only necessary to work on the back side of the seat pad, improving workability.

[0012] In addition, a fourth aspect of the seat according to the present invention is a seat according to the third aspect, wherein the locking portion is inserted into the hole portion and then rotated so as to extend in a direction intersecting the thickness direction in a side view from the seat width direction, thereby becoming a locking portion that is locked to the back side of the seat pad.

[0013] According to the fourth aspect of the invention, the locking portion is inserted into the hole and then rotated so as to extend in a direction intersecting the thickness direction in a side view seen from the seat width direction, thereby becoming a locking portion that is locked to the back side of the seat pad. Therefore, when dismantling the seat pad to remove the trim cover, it is only necessary to rotate the locking portion so as to extend in the thickness direction, improving workability.

[0014] In addition, a fifth aspect of the seat according to the present invention is a seat of the third aspect, wherein the locking portion is a locking portion that is locked to a wire member provided on the back side of the seat pad.

[0015] According to the fifth aspect of the invention, the locking portion is a locking portion that is locked to a wire member provided on the back side of the seat pad. Therefore, when disassembling the seat pad to remove the trim cover, it is only necessary to detach the locking portion from the wire member, improving workability. [Effects of the Invention]

[0016] As described above, according to the present invention, the disassembly work of removing the trim cover from the seat pad can be easily performed. [Brief explanation of the drawings]

[0018] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. For ease of explanation, the arrow UP shown in each drawing indicates the upward direction of the seat, the arrow FR indicates the forward direction of the seat, and the arrow RH indicates the rightward direction of the seat. Furthermore, in the following description, unless otherwise specified, when the directions of up / down, front / rear, and left / right are mentioned, they refer to the up / down, front / rear, and left / right of the seat. Furthermore, the left / right direction is synonymous with the seat width direction.

[0019] First Embodiment First, a first embodiment will be described. As shown in Fig. 1, a seat back 12 constituting a seat 10 has a seat pad 20 that is placed on a seat back frame (not shown) and a trim cover 30 that serves as a cover that is placed on the seat pad 20. The seat pad 20 is formed to a size that can support the back of an occupant (not shown), and has a seat pad main body 22 made of urethane foam or the like, and a plurality of grooves 24, 26 formed on the surface side of the seat pad main body 22.

[0020] Specifically, a pair of first grooves 24 of a predetermined depth are formed extending vertically at a predetermined distance from the approximate vertical center of the seat pad main body 22 downward. Each first groove 24 separates the center side and the side side of the seat pad 20. In other words, the portions of the seat pad 20 that are further outward in the seat width direction than each first groove 24 form the side portions of the seat back 12 that protrude slightly forward.

[0021] Second grooves 26 of a predetermined depth extending in the seat width direction (left-right direction) are formed above each first groove 24 in the seat pad main body 22, with the right end of each second groove 26 continuing with the first groove 24 on the right side and the left end of each second groove 26 continuing with the first groove 24 on the left side. The seat pad main body 22 also has grooves 25 of a predetermined depth that are generally in an inverted U-shape when viewed from the front and continue with the upper ends of each first groove 24. Furthermore, a pair of left and right holes 23 are formed in the upper end surface 22A of the seat pad main body 22, into which headrest stays of a headrest (not shown) are inserted.

[0022] The trim cover 30 has a trim cover main body 32 made of fabric or the like, and first groove portions 34 and second groove portions 36 corresponding respectively to the first groove portions 24 and second groove portions 26 of the seat pad main body 22. As shown in Fig. 2, tongue-shaped clamped portions 35 are integrally provided along each of the first groove portions 34 on the back side of the trim cover main body 32, which faces the front side of the seat pad main body 22.

[0023] 1 is pulled out (peeled off) from the seat pad 20 is downward. The clamped portion 35 is made of the same material as the trim cover main body 32, e.g., is formed by extending a portion of the trim cover main body 32, and extends in the pulling direction when the trim cover 30 is peeled off from the seat pad 20.

[0024] 1, a plurality of (six in each shown) resin clips 14 are embedded in the seat pad main body 22 at predetermined intervals (for example, at equal intervals) along each first groove portion 24. As shown in FIG. 2, each clip 14 (more specifically, a clip main body 14A described later) is integrally connected by a rod-shaped support member 16 extending in the pull-out direction along the first groove portion 24, and is arranged side by side at predetermined intervals in the pull-out direction.

[0025] Each clip 14 has a clip body 14A having an approximately rectangular column shape connected by a support member 16, a pair of protrusions 14B having an approximately obtuse triangular shape when viewed from the front and extending significantly outward in the left-right and up-down directions from the rear side of the outer periphery of the clip body 14A, and a pair of claws 14C extending in a bifurcated manner from the front side of the outer periphery of the clip body 14A toward the front.

[0026] A pair of overhanging portions 14B of each clip 14 is embedded inside the seat pad main body 22 (on both the left and right sides of the first groove portion 24), and the embedded pair of overhanging portions 14B makes it difficult for each clip 14 to come off the seat pad main body 22. Also, a pair of claw portions 14C of each clip 14 extends in a curved shape such that tip portions 14D on the opposite side from the clip main body 14A side approach each other, and the tip portions 14D are configured to be slightly elastically deformable in directions separating from each other.

[0027] A resin guide portion 35A having a generally spindle-shaped cross section is integrally attached to the tip of the clamped portion 35 to make it easier to insert the clamped portion 35 between the pair of claw portions 14C, and the pair of claw portions 14C are configured to be able to clamp the guide portion 35A of the clamped portion 35 from its thickness direction. This makes it easy for the clamped portion 35 (guide portion 35A) to come out of each clip 14 when a force is applied in the pull-out direction along each first groove portion 24 (along the extension direction of the support member 16), but difficult for a force applied in any other direction to come out of each clip 14.

[0028] 3 (the second groove portion 36 in the trim cover 30 is not shown in FIGS. 3 to 6), a hole portion 27 penetrating in the thickness direction is formed in a predetermined region on the seat width direction central side of the second groove portion 26 of the seat pad main body 22. A resin plate portion 40 is inserted into the hole portion 27 from the front side of the seat pad main body 22 and is provided on the back side of the trim cover main body 32 as a locking portion (a locking portion that locks so as not to come off) that is locked on the back side of the seat pad main body 22.

[0029] Specifically, a tongue-shaped insertion portion 37 extending upward is integrally provided below the second groove portion 36 (see FIG. 1) on the back surface side of the trim cover main body 32, and a resin holding member 39 that is generally U-shaped in plan view and open toward the rear is integrally attached to the tip of the insertion portion 37. A generally rectangular, flat plate portion 40 with the seat width direction as its longitudinal direction is supported on the seat width direction inner side of the holding member 39 so as to be rotatable about its axial direction. In other words, central portions of short side portions 40A of the plate portion 40 are pivotally connected to the inner sides of the left and right sides extending toward the rear of the holding member 39, respectively.

[0030] Therefore, after being inserted into the hole 27, the plate portion 40 is rotated so as to extend in a direction intersecting the thickness direction of the seat pad main body 22 (the vertical direction in the drawing) in a side view seen from the seat width direction, thereby being engaged with the rear surface side of the seat pad main body 22. As a result, the clips 14 are clamped by the clamped portions 35, and the trim cover 30 is held so as not to come off the seat pad 20. After the plate portion 40 has been engaged, the guide portions 35A of the clamped portions 35 are inserted between the pair of claw portions 14C of each clip 14.

[0031] Next, the operation (disassembly process) of the seat 10 according to the first embodiment configured as above will be described.

[0032] When dismantling the seat back 12 of the seat 10, specifically when removing the trim cover 30 from the seat pad 20 of the seat back 12, the worker first releases the engagement of the plate portion 40 of the trim cover 30 that is engaged with the back side of the seat pad main body 22 of the seat pad 20.

[0033] This plate portion 40 is inserted from the front side of the seat pad main body 22 into the hole portion 27 that penetrates the thickness direction of the seat pad main body 22, and then, when viewed from the side in the seat width direction, is rotated so that it extends in a direction that intersects with the thickness direction of the seat pad main body 22, thereby engaging with the back side of the seat pad main body 22.

[0034] Therefore, the worker first rotates the plate portion 40 so that it extends in the thickness direction of the seat pad main body 22 in a side view seen from the seat width direction, as shown in Fig. 4, and then passes the rotated plate portion 40 through the hole portion 27, as shown in Figs. 5 and 6. This allows the plate portion 40 to be released from the lock.

[0035] In this way, during disassembly work to remove the trim cover 30 from the seat pad 20, the worker only needs to work on the back side of the seat pad 20 (seat pad main body 22), thereby improving workability. Moreover, the worker only needs to rotate the plate portion 40 so that it extends in the thickness direction of the seat pad 20 (seat pad main body 22) in a side view seen from the seat width direction, and pass it through the hole portion 27, thereby further improving workability.

[0036] After passing the plate portion 40 through the hole portion 27 in this way, the worker pulls downward the trim cover 30 that covers the seat pad 20. Here, a clamped portion 35 is provided on the back side of the trim cover 30 (trim cover main body 32) that faces the front side (first groove portion 24) of the seat pad 20 (seat pad main body 22), and a plurality of clips 14 provided on the seat pad 20 (seat pad main body 22) clamp the clamped portion 35 (guide portion 35A).

[0037] The clamped portions 35 (guide portions 35A) extend along the first groove portions 34, and extend in the pulling direction (downward) when the trim cover 30 is removed from the seat pad 20. The multiple clips 14 are also arranged side by side in the pulling direction (downward). Therefore, by pulling the trim cover 30 in the pulling direction (downward), the plate portions 40 come out of the holes 27, and the clamped portions 35 come out of the multiple clips 14.

[0038] That is, according to the seat 10 according to the first embodiment, when dismantling the seat back 12, it is not necessary to remove each of the clips 14 (one by one) from the clamped portions 35, but rather, by simply pulling out the trim cover 30 in the pulling-out direction (downward), the clamped portions 35 can be removed from the clips 14. This makes it easy to perform the dismantling work of removing the trim cover 30 from the seat pad 20.

[0039] Moreover, the multiple clips 14 are connected by support members 16 that extend in the pulling direction (downward) when removing the trim cover 30 from the seat pad 20. Therefore, during the disassembly work of removing the trim cover 30 from the seat pad 20, the multiple clips 14 are more unlikely to come off the seat pad 20, and the clamped portions 35 are more likely to come off the multiple clips 14. Note that connecting the multiple clips 14 by the support members 16 also has the advantage of making it easier to attach the multiple clips 14 to the seat pad 20.

[0040] Second Embodiment Next, a second embodiment will be described. Note that the same reference numerals are used to designate the same parts as those in the first embodiment, and detailed descriptions (including common functions) will be omitted as appropriate.

[0041] 7, the seat pad main body 22 of the seat pad 20 in this seat back 12 has slit-shaped elongated holes 28 (with the vertical direction as the longitudinal direction) formed along the first groove 24 in a predetermined region excluding the upper and lower ends of the first groove 24. A plurality of clips 14 (five in the figure) are embedded in the seat pad main body 22 along the second groove 26 at predetermined intervals (for example, at equal intervals).

[0042] Although not shown, a clamped portion 35 (see FIG. 2) is integrally provided along the second groove portion 36 on the back side of the trim cover main body 32 (trim cover 30) that faces the front side of the seat pad main body 22. That is, the pull-out direction in this second embodiment is leftward or rightward, and the support member 16 that integrally connects the clips 14 extends in the pull-out direction (left-right direction) along the second groove portion 26.

[0043] 8, a pair of hook portions 38 serving as engaging portions (locking portions) that protrude in the thickness direction of the seat pad main body 22 are integrally provided on the back surface side of the trim cover main body 32 (trim cover 30) along each of the first groove portions 34. Each hook portion 38 is formed of a metal or resin plate whose longitudinal direction is the up-down direction, and its tip portion (rear end portion) is curved in a substantially semicircular arc to form a substantially "J" shape in plan view.

[0044] Each hook portion 38 is adapted to be inserted into a corresponding long hole portion 28, and each hook portion 38 inserted into each long hole portion 28 is adapted to be locked to a pair of wire members 18 provided to extend in the vertical direction on the back surface side of the seat pad main body 22 (for example, installed between the upper and lower portions of a seat back frame not shown). As a result, the clips 14 are clamped by the clamped portions 35, and the trim cover 30 is held so as not to come off the seat pad 20.

[0045] Therefore, during disassembly work to remove the trim cover 30 from the seat pad 20, first, the hook portions 38 are detached from the wire members 18. At this time, the removal may be performed from the back side of the seat pad main body 22 (seat pad 20), or the first groove portions 34 of the trim cover 30 may be removed by pressing the front side in the thickness direction of the seat pad main body 22 (seat pad 20). In either case, the hook portions 38 can be easily detached from the wire members 18, thereby improving workability.

[0046] Once the hook portions 38 are disengaged from the wire members 18, the trim cover 30 is pulled out to the left or right. Here, the clamped portions 35 extend along the second groove portions 36, i.e., the pulling direction (left or right) when removing the trim cover 30 from the seat pad 20, and the multiple clips 14 are also arranged side by side in that pulling direction (left or right). Therefore, simply by pulling the trim cover 30 out in the pulling direction (left or right), the hook portions 38 can pass through the elongated hole portions 28, and the clamped portions 35 are released from the multiple clips 14.

[0047] That is, in the seat 10 according to the second embodiment, too, when dismantling the seat back 12, it is not necessary to remove each of the clips 14 (one by one) from the clamped portions 35, which facilitates the dismantling work of removing the trim cover 30 from the seat pad 20. Moreover, when dismantling the seat 10 to remove the trim cover 30 from the seat pad 20, it is only necessary to remove the hook portion 38 from the wire member 18, which further improves the workability.

[0048] While the seat 10 according to this embodiment has been described above with reference to the drawings, the seat 10 according to this embodiment is not limited to the one shown in the drawings, and the design can be modified as appropriate within the scope of the gist of the present invention. For example, the holding member 39 and the plate portion 40 are not limited to being provided as a single unit, but may be provided as a pair on the left and right, or as a plurality of separate units.

[0049] Furthermore, the number of clips 14 is not limited to the number shown in the figure. Furthermore, the clips 14 and locking portions (engaging portions such as the plate portion 40 and the hook portion 38) are not limited to those provided on the seat back 12 shown in the figure, but may be provided on a seat cushion (not shown). Therefore, the pulling direction of the trim cover 30 is not limited to downward, leftward, or rightward. Furthermore, the locking portions are not limited to those that are engaged.
