Description

[Technical Field]

[0001] The present invention relates to a seat having a hanging portion in which a cover material is hung. [Background technology]

[0002] In a seat having a pad and a cover material covering the pad, a linear recessed suspending portion may be provided on the seating surface of the seat cushion and seat back to maintain the external shape. The cover material is suspended into this suspending portion and fixed to an engaging member fixed to the pad. For example, Patent Document 1 describes a suspending portion formed by engaging a suspending edge portion (suspender) of the cover material with a clip installed in a groove in the pad. The clip includes a base and a pair of engaging portions extending from the base, and the pair of engaging portions engage the suspending edge portion of the cover material.

[0003] The pad is made of a foam resin with cushioning properties, such as urethane foam. After being foam-molded in a mold, the pad is removed from the mold and crushed by roller crushing. Roller crushing is a process performed to break the membranes (cells) of air bubbles that are generated during foam molding of the foam resin, and to stabilize the hardness and sag characteristics of the pad. In the clip described in Patent Document 1, raised portions provided on the outside of the pair of engaging parts abut against the pair of engaging parts that are elastically deformed by the rollers during roller crushing, thereby preventing the pair of engaging parts from being excessively deformed.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-186324 Summary of the Invention

[0005] The structure described in Patent Document 1 can prevent excessive deformation of the clip during roller crushing, but the force applied to the clip from the roller applies force between the clip and the pad, causing the clip to shift from its specified position or reducing the fixing force of the clip from the pad, which could result in insufficient hanging of the covering material and a decrease in the design.In addition, when attaching the hanging edge to the clip, excessive force could be applied from the hanging edge to the clip, causing the clip to shift position relative to the pad and a decrease in the design of the hanging part. [Problem to be solved by the invention]

[0006] In view of the above background, an object of the present invention is to provide a sheet in which clips are prevented from shifting in position. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, one aspect of the present invention is a sheet (1) having a hanging portion (5), comprising: a pad (6) having a surface provided on one side in a thickness direction and a back surface provided on the other side in the thickness direction, the pad (6) containing a foamed resin with cushioning properties; a cover material disposed on at least the surface of the pad (6) and including a hanging edge portion (11) extending toward the pad (6); a hanging groove (8) provided on the surface of the pad (6) for receiving the hanging edge portion (11); a base (15) embedded in the bottom of the hanging groove (8); The hanging groove (8) includes a locking portion (16) extending toward the hanging edge portion (11), a plurality of clips (9) for locking the hanging edge portion (11), a first hook-and-loop fastener (31) attached to the bottom of the hanging groove (8), a second hook-and-loop fastener (32) attached to the hanging edge portion (11) and engaged with the first hook-and-loop fastener (31), and a positioning protrusion (14) protruding from the bottom of the hanging groove (8) toward the surface side in the thickness direction, and the positioning protrusion (14) and the clips (9) are positioned to sandwich the first hook-and-loop fastener (31) in the extending direction of the hanging groove (8). The pad (6) may include the positioning protrusion (14), and the first hook-and-loop fastener (31) may be arranged in the vicinity of the positioning protrusion (14). The clip (9) includes an extension (17) extending from the base (15) and the engaging portion (15) in the extension direction, and the extension (17) may not extend into the positioning protrusion (14) or a portion of the pad (6) near the positioning protrusion (14). The length of the first hook-and-loop fastener (31) in the extension direction may be longer than the length of the second hook-and-loop fastener (32) in the extension direction. The side of the positioning protrusion (14) facing the clip (9) may include, on the front surface side in the thickness direction, an inclined surface (23) that is inclined away from the clip (9), and the second hook-and-loop fastener (32) may be disposed on the back surface side in the thickness direction relative to the inclined surface (23).The hanging edge portion (11) may include an engaged portion (13) that is engaged with the clip (9), and the second hook-and-loop fastener (32) may be arranged on the back surface side of the engaged portion (13) in the thickness direction. The first hook-and-loop fastener (31) may be arranged above the base portion (15) of the clip (9). The length of the clip (9) along the extension direction may be longer than the length of the first hook-and-loop fastener (31) along the extension direction. The first hook-and-loop fastener (31) and the second hook-and-loop fastener (32) may be arranged at a position offset from the clip (9) in the extension direction. The portions of the pad (6) that form the bottom of the hanging groove (8) corresponding to each of the clips (9) are provided with individual easily deformable portions (25) that are more easily deformable than the surrounding portions of the pad (6), and the first hook-and-loop fastener and the second hook-and-loop fastener may be positioned at positions offset from the easily deformable portions in the extension direction.

[0008] According to this aspect, by engaging the first and second hook-and-loop fasteners with each other and then engaging the hanging edge with the clip, it is possible to prevent the clip from shifting position relative to the pad and suppress deterioration of the design of the hanging portion. According to the aspect including the easily deformable portion, when the pad is roller crushed during the manufacturing process, the easily deformable portion is provided around the clip, so that the clip is displaced toward the easily deformable portion, suppressing excessive force being applied to the clip. This suppresses deterioration of the design of the hanging portion.

[0009] In the above aspect, the easily deformable portion (25) may include a recess provided on the back surface of the pad (6).

[0010] According to this aspect, the easily deformable portion can be easily formed.

[0011] In the above aspect, both ends of the clip (9) may be located inward of both ends of the easily deformable portion (25) in the extension direction and / or width direction of the hanging groove (8).

[0012] According to this aspect, the clip is more likely to be displaced toward the easily deformable portion during roller crushing, thereby preventing excessive force from being applied to the clip.

[0013] In the above aspect, the contour of the clip (9) may be located inside the contour of the easily deformable portion (25) when viewed in the thickness direction.

[0014] According to this aspect, the clip is more likely to be displaced toward the easily deformable portion during roller crushing, thereby preventing excessive force from being applied to the clip.

[0015] In the above aspect, the distance from the bottom surface of the clip (9) to the bottom surface of the corresponding easily deformable portion (25) may be longer than the depth of the easily deformable portion (25).

[0016] According to this aspect, it is possible to prevent the thickness of the bottom of the hanging groove in which the clip is embedded from becoming thin, and therefore it is possible to prevent a decrease in the holding force of the clip by the pad.

[0017] In the above aspect, the pad (6) may include a positioning protrusion (14) protruding from the bottom of the hanging groove (8) toward the surface, the clip (9) may include an end clip (9a) provided adjacent to the positioning protrusion (14), and the end clip may include an extension (17) that protrudes into the positioning protrusion and / or a portion of the pad adjacent to the positioning protrusion on the back side.

[0018] According to this aspect, the extension is supported by the pad, and therefore the holding force of the pad on the clip is improved.

[0019] In the above embodiment, the locking portion (16) includes a pair of locking pieces (19) extending from the base (15), and each of the pair of locking pieces (19) includes a locking claw (20) that extends from its free end in a direction approaching each other in the width direction of the hanging groove and locks the hanging edge portion (11), and the extension portion (17) includes a free end extension portion (22) that extends from each of the locking claws (20) in directions away from each other in the extension direction of the hanging groove (8), one of which protrudes into the positioning protrusion (14).

[0020] According to this aspect, the free end extension is supported by the positioning protrusion, which improves the holding force of the clip by the pad. Also, because the free end extension extends in both directions of the extension of the hanging groove, it is possible to prevent the clip from being attached in the wrong direction when assembling the clip to the pad.

[0021] In the above aspect, a part of the pad is present between the pair of locking pieces.

[0022] According to this aspect, the pad inserted between the pair of locking pieces prevents the hanging member from moving backward in the thickness direction.

[0023] In the above aspect, the positioning protrusion (14) may at least partially overlap the easily deformable portion (25) corresponding to the end clip (9a) when viewed in the thickness direction.

[0024] According to this aspect, the positioning protrusion at least partially overlaps the easily deformable portion when viewed from the thickness direction, so that the positioning protrusion can compensate for the reduction in cushioning properties of the pad caused by the provision of the easily deformable portion, and the pad can be made more compact in the extension direction of the hanging groove compared to when the positioning protrusion and the easily deformable portion do not overlap each other.

[0025] In the above aspect, the side surface of the positioning protrusion (14) on the side of the end clip (9a) may include an inclined surface that is inclined so that the surface side is away from the end clip (9a).

[0026] According to this aspect, the positioning protrusion is provided with an inclined surface, which prevents the portion of the hanging edge on the surface side in the thickness direction (skin extension portion) from hitting the positioning protrusion. [Effects of the Invention]

[0027] According to the above-mentioned aspects, by engaging the first and second hook-and-loop fasteners with each other and then engaging the hanging edge with the clip, it is possible to prevent the clip from shifting position relative to the pad, and it is possible to provide a sheet in which deterioration of the design of the hanging part is suppressed. According to the aspect in which the easily deformable part is provided, it is possible to provide a sheet in which excessive force is suppressed from being applied to the clip when the pad is roller crushed.

[0028] According to an aspect in which the easily deformable portion includes a recess, the easily deformable portion can be easily formed.

[0029] According to an embodiment in which both ends of the clip are located inward of both ends of the easily deformable portion, it is further possible to prevent excessive force from being applied to the clip during roller crushing.

[0030] According to an embodiment in which the contour of the clip is located inside the contour of the easily deformable portion when viewed in the thickness direction, application of excessive force to the clip during roller crushing is further suppressed.

[0031] In an embodiment in which the distance from the bottom surface of the clip to the bottom surface of the corresponding easily deformable portion is longer than the depth of the easily deformable portion, it is possible to suppress a decrease in the holding force of the clip by the pad.

[0032] According to the aspect in which the extension portion projects into the positioning protrusion and / or its periphery, the holding force of the clip by the pad is improved.

[0033] In an embodiment including free end extensions on both sides of the extension direction, the holding force of the clip by the pad is improved and the clip is prevented from being attached in the wrong direction when assembled to the pad.

[0034] In the embodiment in which a part of the pad is present between the pair of locking pieces, movement of the hanging member toward the rear side in the thickness direction is suppressed.

[0035] According to an embodiment in which the positioning protrusion at least partially overlaps the easily deformable portion, it is possible to suppress a decrease in the cushioning properties of the pad and to make the pad more compact.

[0036] According to the aspect in which the positioning protrusion is provided with an inclined surface, the portion of the hanging edge on the surface side in the thickness direction is prevented from hitting the positioning protrusion. [Brief explanation of the drawings]

[0038] Hereinafter, a sheet 1 according to an embodiment of the present invention will be described with reference to the drawings.

[0039] As shown in Fig. 1, the seat 1 is a vehicle seat that includes a seat cushion 2 that supports the buttocks of a seated occupant, a seat back 3 that supports the back of the seated occupant, and a headrest 4 that supports the head of the seated occupant. The seating surfaces of the seat cushion 2 and the seat back 3 are each provided with a plurality of linearly recessed hanging portions 5.

[0040] As shown in Figures 2 to 5, the seat cushion 2 and the seat back 3 each include a metal frame (not shown), a support member 26 supported by the metal frame, a pad 6 supported by the support member 26, a cover material 7 covering the pad 6, a hanging groove 8 provided in the pad 6 to form the hanging portion 5, and a plurality of clips 9 that engage the cover material 7 within the hanging groove 8 to form the hanging portion 5.

[0041] The pad 6 contains a foamed resin having cushioning properties, such as urethane foam. The pad 6 has a front surface provided on one side in the thickness direction and a back surface provided on the other side in the thickness direction. The back surface of the pad 6 is supported by a support member 26. In the seat cushion 2 (see FIG. 1), the thickness direction generally coincides with the up-down direction, and the front surface is the upper surface. In the seat back 3, the thickness direction generally coincides with the front-rear direction of the vehicle, and the front surface is the front surface.

[0042] The cover material 7 is disposed on the surface of the pad 6. In the seat cushion 2 (see FIG. 1), the cover material 7 is disposed not only on the surface (top surface) of the pad 6 but also on the front surface and left and right side surfaces. In the seat back 3, the cover material 7 is disposed not only on the surface (front surface) of the pad 6 but also on the left and right side surfaces and top surface. The cover material 7 includes a cover main body portion 10 that covers the surface of the pad 6, and a hanging edge portion 11 that extends toward the pad 6 and is received in the hanging groove 8. The hanging edge portion 11 is received in the hanging groove 8 and is engaged with the clip 9, thereby forming the hanging portion 5.

[0043] The hanging edge 11 extends in the extension direction of the hanging groove 8. The hanging edge 11 has a cloth-like skin extension 12 connected to the ends of the two skin main body portions 10 by sewing or the like, and includes a locking portion 13 connected to the end of the skin extension 12 on the back side in the thickness direction and locked by the clip 9. The locking portion 13 has a shape that bulges out on both sides in the width direction of the hanging groove 8 relative to the skin extension 12. For example, the skin extension 12 may be made of nonwoven fabric, and the locking portion 13 may be formed by injection molding, and the skin extension 12 may be connected to the locking portion 13 by being attached to a cavity of a mold during molding of the locking portion 13. Alternatively, for example, the skin extension 12 and the locking portion 13 may be formed from the same resin, and the hanging edge 11 may be formed by extrusion molding.

[0044] The hanging groove 8 is provided on the surface of the pad 6 and receives the hanging edge 11. The pad 6 includes a positioning protrusion 14 that protrudes from the bottom of the hanging groove 8 toward the surface. The positioning protrusion 14 abuts against the end of the engaging portion 13 of the hanging edge 11 in the extension direction, thereby restricting displacement of the hanging edge 11 in the extension direction.

[0045] The clip 9 includes a base 15 embedded in the bottom of the hanging groove 8 and a locking portion 16 extending from the base 15 toward the surface in the thickness direction to lock onto the locked portion 13 of the hanging edge portion 11. The clip 9 includes an end clip 9a located near the end of the hanging groove 8 in the extension direction, and a middle clip 9b located in the middle of the hanging groove 8 in the extension direction. The end clip 9a includes an extension portion 17 extending from the base 15 and the locking portion 16 in the extension direction of the hanging groove 8. The middle clip 9b may have the same structure as the end clip 9a, or may have a structure omitting the extension portion 17. The clip 9 is made of resin and manufactured by injection molding or the like. The clip 9 is embedded in the pad 6 by being placed in a mold for the pad 6 during foam molding of the pad 6.

[0046] The base 15 has a generally flat plate shape perpendicular to the thickness direction and has a plurality of through holes 18 penetrating in the thickness direction. The through holes 18 are filled with foam resin that constitutes the pad 6. The locking portion 16 includes a pair of locking pieces 19 that are arranged offset from each other in the extension direction and width direction of the hanging groove 8. The base ends of the pair of locking pieces 19 are embedded in the pad 6, and the free ends of the pair of locking pieces 19 protrude from the pad 6. Each of the pair of locking pieces 19 includes a locking claw 20 that extends from its free end in directions approaching each other in the width direction of the hanging groove 8 and locks the locked portion 13 of the hanging edge portion 11. When viewed in the thickness direction, the extending edges of the pair of locking claws 20 are parallel to each other, and the distance between the extension lines of the extending edges is equal to or greater than the width of the locked portion 13. Furthermore, the shortest distance between the pair of locking claws 20 in the width direction of the hanging groove 8 is less than the width of the locked portion 13. It is preferable that the distance from the bottom surface of the hanging groove 8 to the locking claws 20 is approximately equal to the height of the locked portion 13 (the length from the surface facing the bottom surface of the hanging groove 8 to the surface abutting against the locking claws 20).

[0047] The extensions 17 include base extensions 21 that extend from the base 15 in both directions in the extension direction of the hanging groove 8, and free end extensions 22 that extend from each of the locking claws 20 in directions that are opposite to each other in the extension direction of the hanging groove 8. Of the two base extensions 21 in each end clip 9a, the tip of the base extension 21 that extends toward the positioning protrusion 14 protrudes into a portion of the pad 6 that is adjacent to the back side of the positioning protrusion 14. Of the two free end extensions 22 in each end clip 9a, the tip of the free end extension 22 that extends toward the positioning protrusion 14 protrudes into the positioning protrusion 14.

[0048] The side surface of the positioning protrusion 14 on the end clip 9a side includes an inclined surface 23 that is inclined so that the surface side is away from the end clip 9a, on the surface side in the thickness direction from the portion where the free end extension 22 protrudes. The end of the hanging edge 11 in the extension direction of the skin extension 12 includes an inclined edge 24 that faces the inclined surface 23.

[0049] The pad 6 has, corresponding to each clip 9, an individual easily deformable portion 25 in the portion of the pad 6 that forms the bottom of the hanging groove 8, which is more easily deformable than the surrounding portion of the pad 6. The easily deformable portion 25 includes a recess provided on the back surface of the pad 6. The recess is defined in the foamed resin that constitutes the pad 6. In the extension direction and width direction of the hanging groove 8, both ends of the clip 9 are located more inward than both ends of the easily deformable portion 25. Preferably, when viewed in the thickness direction, the outline of the clip 9 is located inside the outline of the easily deformable portion 25. Therefore, the easily deformable portion 25 is also present on the back surface in the thickness direction of the portion of the positioning protrusion 14 into which the extension portion 17 of the end clip 9a protrudes. In addition, the bottom surface of the recess that constitutes the easily deformable portion 25 is parallel to the bottom surface of the base 15 of the corresponding clip 9 and the bottom surface around the easily deformable portion 25 on the pad 6, and the distance from the bottom surface of the base 15 of the clip 9 to the bottom surface of the recess that constitutes the corresponding easily deformable portion 25 is longer than the depth of the recess that constitutes the easily deformable portion 25.

[0050] If a member (not shown) for preventing noise from being generated between the pad 6 and a metal frame (not shown) arranged on the back side of the pad 6 is provided on the back side of the pad 6, the easily deformable portion 25 may include a through-hole provided in the noise generation prevention member. Moreover, instead of a recess, the easily deformable portion 25 may be made of foamed resin that is more easily deformed than the surrounding portion of the pad 6.

[0051] As shown in FIG. 5 , in the seat back 3, the clip 9 and the easily deformable portion 25 are positioned to avoid the center of the seat back 3 in the left-right direction. Furthermore, the wire 27 supporting the support member 26 includes a bent portion 28 for increasing the amount of deflection of the wire 27 at a position that is approximately aligned with the easily deformable portion 25 in the up-down and left-right directions. When the vehicle collides with another vehicle or another object and a large load is applied to the seat back 3 by the occupant, the pad 6 compresses, causing the occupant's back to sink into the seat back 3, thereby absorbing the impact on the occupant. At this time, since the easily deformable portion 25 is positioned to avoid the center of the seat back 3 in the left-right direction, the easily deformable portion 25 does not impede the impact-absorbing function of the pad 6. Furthermore, the presence of the bent portion 28 of the wire 27 at a position that is approximately aligned with the easily deformable portion 25 in the up-down and left-right directions also contributes to increasing the amount of sinking of the occupant into the seat back 3.

[0052] A method of attaching the hanging edge portion 11 to the clip 9 will be described with reference to FIG. 6. First, as shown in FIG. 6(A), the worker tilts the locked portion 13 in the width direction relative to the extending direction of the hanging groove 8 (see FIGS. 2 to 4). Next, as shown in FIG. 6(B), the worker inserts the locked portion 13 between a pair of locking claws 20. Because the distance between the extension lines of the parallel extending edges of the pair of locking claws 20 is equal to or greater than the width of the locked portion 13, tilting the locked portion 13 in the width direction makes it easy to insert the locked portion 13 between the pair of locking claws 20. Next, as shown in FIG. 6(C), the worker rotates the locked portion 13 about an axis that passes through the center of the clip 9 and is parallel to the extending direction of the hanging groove 8. Since the shortest distance between a pair of locking claws 20 in the width direction of the hanging groove 8 is less than the width of the locked portion 13, in the state shown in Figure 6 (C), even if the hanging edge portion 11 is pulled toward the surface, the locked portion 13 is locked by the pair of locking claws 20.

[0053] The effects of the sheet 1 according to the embodiment will be described. During roller crushing in the manufacturing process, the pad 6 receives force in the thickness direction from the roller. At this time, the easily deformable portion 25 is provided on the back side of the clip 9 in the thickness direction, so the clip 9 displaces toward the easily deformable portion 25. This prevents excessive force from being applied to the clip 9 from the roller. After the roller passes, the clip 9 returns to its original position due to the elasticity of the pad 6. Furthermore, both ends of the clip 9 are positioned inward of both ends of the easily deformable portion 25 in the extension direction and / or width direction of the hanging groove 8. Preferably, the contour of the clip 9 is positioned inside the contour of the easily deformable portion 25 when viewed from the thickness direction. This makes it easier for the clip 9 to displace toward the easily deformable portion 25 during roller crushing, thereby reducing the force applied to the clip 9 from the roller. This prevents deformation and misalignment of the clip 9 and prevents a reduction in the design of the hanging portion 5.

[0054] Because an individual easily deformable portion 25 is provided for each clip 9, the reaction force of the pad 6 against the roller is greater in areas where there are no clips 9 than in areas where there are clips 9. This reduces the force applied from the roller to the clips 9. Furthermore, because an individual easily deformable portion 25 is provided for each clip 9, the ratio of the area where the easily deformable portion 25 is formed to the entire pad 6 is reduced when viewed in the thickness direction, and this reduces the decrease in cushioning properties.

[0055] The inclusion of a recess in easily deformable portion 25 makes it easy to form easily deformable portion 25 on pad 6. Furthermore, the distance from the bottom surface of base 15 of clip 9 to the bottom surface of the corresponding recess constituting easily deformable portion 25 is longer than the depth of the recess constituting easily deformable portion 25, thereby preventing easily deformable portion 25 from reducing the holding force of clip 9 by pad 6.

[0056] By providing the positioning protrusion 14, when inserting the hanging edge portion 11 into the hanging groove 8, it becomes easy to position the hanging edge portion 11 in the hanging groove.

[0057] The tip of the base extension 21 of the end clip 9a protrudes into the portion of the pad 6 adjacent to the positioning protrusion 14 on the back side, and the tip of the free end extension 22 of the end clip 9a protrudes into the positioning protrusion 14, thereby improving the support force of the end clip 9a by the pad 6. In addition, the support force of the pad 6 for the end clip 9a is also improved by filling the through hole 18 provided in the base 15 of the clip 9 with the foam resin that constitutes the pad 6.

[0058] Since the extensions 17 are provided on both longitudinal sides of the end clip 9a, it is possible to prevent the end clip 9a from being attached to the pad 6 in the wrong direction.

[0059] Since the positioning protrusion 14 partially overlaps the easily deformable portion 25 in the thickness direction of the pad 6, the positioning protrusion 14 can compensate for the decrease in cushioning properties of the pad 6 caused by the provision of the easily deformable portion 25, and the pad 6 can be made more compact in the extension direction of the hanging groove 8 compared to when the positioning protrusion 14 and the easily deformable portion 25 do not overlap each other.

[0060] Since the positioning protrusion 14 is provided with the inclined surface 23, the skin extension 12 of the hanging edge 11 can be prevented from hitting the positioning protrusion 14.

[0061] The base ends of the pair of locking pieces 19 are embedded in the pad 6, and the foam resin constituting the pad 6 also fills in between the pair of locking pieces 19. Therefore, the portion of the pad 6 that fills in between the pair of locking pieces 19 prevents the locked portion 13 from moving toward the back surface in the thickness direction.

[0062] First to third modified examples of the above embodiment will be described with reference to Figures 7 to 9. The same components as those in the above embodiment will be given the same reference numerals and the description thereof will be omitted.

[0063] 7 and the second modified example shown in FIG. 8 differ from the above embodiment in that they include a first hook-and-loop fastener 31 attached to the bottom of the hanging groove 8 and a second hook-and-loop fastener 32 attached to the back surface of the hooked portion 13 of the hanging edge 11 in the thickness direction and engaged with the first hook-and-loop fastener 31. The first and second hook-and-loop fasteners 31, 32 are arranged at positions offset from the clips 9 in the extending direction of the hanging groove 8. In the first modified example, the first hook-and-loop fastener 31 is arranged near the positioning protrusion 14, and the second hook-and-loop fastener 32 is arranged at the end of the hanging edge 11 in the extending direction, and the extension portion 17 of the end clip 9a does not extend into the positioning protrusion 14 or its vicinity. In the second modified example, the first hook-and-loop fastener 31 is arranged midway between adjacent clips 9, and the second hook-and-loop fastener 32 is arranged midway in the extending direction of the hanging edge 11.

[0064] When attaching hanging edge 11 to clip 9, excessive force may be applied from hanging edge 11 to clip 9, causing clip 9 to shift position relative to pad 6 and deteriorating the design of hanging portion 5. Therefore, by attaching hanging edge 11 to clip 9 after engaging first and second hook-and-loop fasteners 31, 32 with each other, it is possible to prevent excessive force from being applied to clip 9 from hanging edge 11, prevent clip 9 from shifting position relative to pad 6, and suppress deterioration in the design of hanging portion 5.

[0065] 9 differs from the above embodiment in that a slit 33 is provided in the positioning protrusion 14, through which the hanging edge 11 is inserted. In the extension direction of the hanging groove 8, the tip of the base extension 21 is preferably located distal to the end of the slit 33. By providing the slit 33, the end of the hanging edge 11 is stabilized.
