[0002] A seat such as a car seat has a structure in which a cushion pad formed of a resin material or the like is covered with a decorative member formed of leather or vinyl leather, etc. in a seat cushion supporting the buttocks of a seated person and / or a seat back supporting the back of a seated person. The decorative member is fixed to the cushion pad on the back side (the side opposite to the side contacting the buttocks or the back) of the cushion pad.

[0003] Patent document 1 discloses the following structure, which is a structure in which a plurality of grooves are provided on the back of a cushion, and a resin clamp is inserted into the plurality of grooves respectively to fix the decorative part. The resin clamp used in the structure of patent document 1 has a structure in which a decorative part fixing part, a plate-shaped base part and a pressing part are integrally formed, the decorative part fixing part fixes the end edge of the decorative part, the plate-shaped base part is inserted into the groove of the cushion, and the pressing part extends from the lower end of the base part (the end part inserted into the groove) toward the opening side of the groove and has flexibility. Moreover, in a state in which the base part and the pressing part of the resin clamp have been inserted into the groove, the pressing part will add an outward pressing force (outward in the cross-sectional direction of the groove) to the side wall surface of the groove. The structure disclosed in patent document 1 can install and remove decorative parts from the cushion with high operability.

[0004] However, the structure disclosed in the above-mentioned Patent Document 1 is in a state where tension always acts on the resin clamp in the state where it is inserted into the groove of the cushion in the fixing direction (cross-sectional direction of the groove) of fixing the decorative part to the decorative part fixing part. In addition, there is a possibility that the resin clamp is heated. For example, there is a situation where the resin clamp is heated by direct sunlight irradiating the seat arranged indoors, or the resin clamp is heated by the seat arranged in the car as the temperature in the car rises.

[0005] As described above, when the resin holder is heated, the resin holder, which is a member made of a resin material, has the characteristic of being easily plastically deformed by heat, and therefore the resin holder may fall off from the groove of the cushion pad. Furthermore, when the resin holder falls off from the groove, a part of the decorative member also leaves the cushion pad together with the resin holder.

In addition, a plurality of grooves 11c are provided on the back side 11b of the cushion pad 11 along the outer edge of the hard pad 111. Each of the plurality of grooves 11c has a long rectangular opening.

[0034] 2. Structure of the groove 11c and its surroundings

[0035] use Figure 3 The structure of the groove portion 11c and its surrounding portion will be described. Figure 3 One of the grooves 11c provided on the back surface 11b of the cushion pad 11 is selected and shown in the figure, and the other grooves 11c also have the same structure. Figure 3 The relationship between the X direction and the Y direction in φ and the direction of the groove 11 c changes depending on the arrangement position of the groove 11 c.

[0036] like Figure 3 As shown, the groove portion 11c has a rectangular opening that is long in the Y direction. The groove portion 11c is provided so as to be recessed from the back surface 11b of the cushion pad 11 in the Z direction (toward the upper surface 11a side).

[0037] The cushion pad 11 has two communicating grooves 11e disposed adjacent to the groove 11c and in the longitudinal direction (Y direction) of the groove 11c. The communicating grooves 11e are disposed on the back side 11b of the cushion pad 11 at a portion opposite to the edge portion and have a semicircular opening.

[0038] The two connecting grooves 11e are arranged at a distance from each other along the longitudinal direction (Y direction) of the groove 11c. The connecting groove 11e is provided at substantially the same depth as the groove 11c and is provided to be continuous with the groove 11c over the entire depth direction.

[0039] In addition, the purpose of forming the communication groove portion 11e will be described later.

[0040] 3. Structure for fixing the decorative part 12 to the cushion 11

[0041] use Figure 4 and Figure 5 The structure of fixing the decorative member 12 to the cushion pad 11 in the seat cushion 10 will be described. Figure 5 It is magnified Figure 4 An enlarged cross-sectional view of part A.

[0042] like Figure 4 and Figure 5As shown, in the back side 11b of the cushion pad 11, the hard pad 111 is exposed to the outside at the edge portion of the back side 11b. The decorative member 12 is arranged so as to cover the area from the upper surface 11a of the cushion pad 11 to the edge portion of the back side 11b. And, the edge portion 12a of the decorative member 12 arranged on the back side 11b of the cushion pad 11 is fixed to the resin clamp 13. In the seat 1, the same number of resin clamps 13 as the number of grooves 11c provided in the cushion pad 11 is provided.

[0043] like Figure 5 As shown, as an example, the resin clamp 13 is formed of polypropylene and has a decoration fixing portion 13a, a base portion 13b and a bent portion 13d in a continuously formed manner. The decoration fixing portion 13a is a portion to which the end edge portion 12a of the decoration 12 is fixed, and is provided in a manner extending toward the edge of the cushion pad 11 along the back surface 11b of the cushion pad 11.

[0044] The upper end in the Z direction of the base portion 13b is continuous with the right end in the X direction of the decoration fixing portion 13a, and the base portion 13b is formed so as to extend in the Z direction and be inserted into the groove portion 11c. In addition, the length of the base portion 13b in the Z direction is set to a length that allows the bottom end 13c to approach the bottom of the groove portion 11c.

[0045] The bent portion 13d is continuous with the bottom end 13c of the base portion 13b and is provided in a cross-sectional shape that is curved in an arc shape toward the opening side of the groove portion 11c. The bent portion 13d is provided at a distance from the base portion 13b to the left in the X direction except for the portion continuous with the base portion 13b. Furthermore, the bent portion 13d can be provided in a flexural manner with the portion continuous with the base portion 13b as a base point.

[0046] In addition, Figure 4 and Figure 5 , the left direction of the X direction corresponds to the "first direction", the right direction of the X direction corresponds to the "second direction", the Z direction corresponds to the "third direction", and the direction perpendicular to the paper surface (the long side direction of the groove 11c) corresponds to the "fourth direction".

[0047] 4. Detailed Structure of Resin Clamp 13

[0048] use Figure 6 The detailed structure of the resin clamp 13 is described. Figure 6 In the figure, one of the multiple resin clamps 13 is also selected for illustration. Figure 6 The relationship between the X direction and the Y direction in FIG. 1 and the direction of the resin holder 13 varies depending on the arrangement position of each resin holder 13 .

[0049] like Figure 6As shown, the resin clamp 13 has a long strip shape whose dimension in the Y direction is longer than the dimensions in the X direction and the Z direction, and is formed to match the dimensions of the inserted groove 11c. The dimension in the Y direction of the resin clamp 13 is set to 50 mm to 150 mm, for example. Moreover, the dimension in the X direction of the resin clamp 13 is set to 15 mm to 25 mm, for example. In addition, the dimension in the Z direction of the resin clamp 13 is set to 15 mm to 25 mm, for example.

[0050] As described above, the bent portion 13d is continuous with the base portion 13b at the bottom end 13c of the base portion 13b, and is provided in a manner that bends and extends in an arc shape from the continuous portion toward the distal end 13i upward in the Z direction. In the bent portion 13d, the portion continuous with the base portion 13b corresponds to "one end", and the distal end 13i corresponds to "the other end".

[0051] A recessed portion 13j is provided at a portion where the curved portion 13d and the base portion 13b are continuous. The recessed portion 13j is a portion that is recessed from the junction of the outer surface of the base portion 13b on the left side in the X direction and the outer surface of the curved portion 13d on the right side in the X direction toward the bottom end 13c. The purpose of providing the recessed portion 13j is to make it easier for the curved portion 13d to bend with the portion where the base portion 13b and the curved portion 13d are continuous as a base point.

[0052] The distal end 13i of the bent portion 13d is disposed at a distance G1 from the outer surface of the lower side in the Z direction of the garnish fixing portion 13a and at a distance G2 from the outer surface of the left side in the X direction of the base portion 13b, and is a free end.

[0053] The thickness of the curved portion 13d is set to be thinner than the thickness of the base portion 13b. Thus, by setting the thickness of the curved portion 13d to be thinner than the thickness of the base portion 13b, when the base portion 13b and the curved portion 13d are inserted into the groove portion 11c, the curved portion 13d is bent due to the reaction force from the side wall surface of the groove portion 11c, and the base portion 13b is not bent. In addition, in the present embodiment, the thickness of the base portion 13b is set to a range of 1.0 mm to 4.0 mm, and the thickness of the curved portion 13d is set to be thinner than the base portion 13b within a range of 1.0 mm to 2.5 mm.

[0054] The resin clamp 13 further includes a recess 13e, a barb (third barb) 13f, a barb (second barb) 13g, and a barb (first barb) 13h. The recess 13e is a portion of the garnish fixing portion 13a that is formed so as to be recessed from the outer surface on the lower side in the Z direction to the upper side in the Z direction, and is used when fixing the garnish 12.

[0055] The barb 13h is continuous with the portion between the portion of the curved portion 13d that is continuous with the base portion 13b and the distal end 13i, and is formed so as to extend obliquely upward to the left. The portion of the curved portion 13d that is continuous with the barb 13h is the portion of the curved portion 13d that is located on the leftmost side in the X direction, and is the middle portion between the portion that is continuous with the base portion 13b and the distal end 13i in the Z direction. The distal end portion 13h1 of the barb 13h is formed in a tapered shape so as to point obliquely upward to the left (the back surface 11b of the cushion pad 11).

[0056] The barb portion 13g is formed to extend from the vicinity of the bottom end 13c in the base portion 13b toward the right in the X direction (the direction opposite to the side where the bent portion 13d is located) and toward the upper side in the Z direction. The distal end portion 13g1 of the barb portion 13g is formed to be tapered so as to point to the upper right side (the back side 11b of the cushion pad 11). In the Z direction, the distal end portion 13h1 of the barb portion 13h and the distal end portion 13g1 of the barb portion 13g are arranged at positions with substantially the same height.

[0057] The barb portion 13f is provided in a portion slightly below the portion of the base portion 13b that is continuous with the decorative member fixing portion 13a. The barb portion 13f is formed in a manner extending toward the right in the X direction (the direction opposite to the side where the curved portion 13d is located) and toward the upper part in the Z direction, similarly to the above-mentioned barb portion 13g. The distal end portion 13f1 of the barb portion 13f is also formed in a gradually tapering shape so as to point to the upper right (the back side 11b of the cushion 11). In addition, the barb portion 13f has a planar portion 13f2 extending in a direction orthogonal to the Z direction near the distal end portion 13f1. The planar portion 13f2 is formed in a manner extending in a direction approximately orthogonal to the outer surface of the right side of the base portion 13b in the X direction.

[0058] 5. Structure for mounting the resin clamp 13 in the groove 11c of the cushion pad 11

[0059] use Figure 7 The structure for attaching the resin clamp 13 to the groove 11c of the cushion pad 11 will be described. Figure 7 In the figure, one group of the plurality of grooves 11c and the plurality of resin clamps 13 is selected and shown. Figure 7 The relationship between the X direction and the Y direction and the direction of the groove portion 11 c and the resin clamp 13 varies depending on each position.

[0060] like Figure 7As shown, in the seat cushion 10, the base portion 13b and the bent portion 13d of the resin clamp 13 are inserted into the groove portion 11c of the cushion pad 11 in a state where the end edge portion 12a of the decorative member 12 is fixed to the decorative member fixing portion 13a. In addition, a recessed portion 11f is provided on the back surface 11b of the cushion pad 11, which is continuous with the left side of the groove portion 11c in the X direction. The depth of the recessed portion 11f in the Z direction is set to be substantially the same as the thickness of the decorative member fixing portion 13a of the resin clamp 13. Therefore, in a state where the base portion 13b and the bent portion 13d of the resin clamp 13 are inserted into the groove portion 11c, the decorative member fixing portion 13a is accommodated in the recessed portion 11f.

[0061] The base 13b inserted into the groove 11c is arranged so that the bottom end 13c approaches the bottom of the groove 11c. The base 13b is arranged so that both outer surfaces in the X direction are separated from both side wall surfaces 11c1 and 11c2 of the groove 11c.

[0062] Here, when the base 13b and the bent portion 13d are inserted into the groove 11c, they are subjected to a pressing force in the groove width direction (X direction) that causes the distal end 13i of the bent portion 13d to approach the base 13b, compared to a free state in which the resin holder 13 is not inserted into the groove 11c. Furthermore, in the groove 11c, the base 13b and the bent portion 13d always exert a reaction force in the X direction that opposes the pressing force.

[0063] The curved portion 13d is arranged with a distance from the recessed portion 11c3 and the portion below the recessed portion 11c3 relative to the side wall surface 11c2 on the left side in the X direction of the groove portion 11c, and the recessed portion 11c3 is provided in the middle portion of the side wall surface 11c2 in the Z direction. The curved portion 13d is formed into a shape in which the distal end 13i points to the side wall surface 11c2 side (first direction) and gradually tapers from the vicinity of the distal end 13i to the distal end 13i. Moreover, the distal end 13i of the curved portion 13d is in a state (inserted state) slightly pressed into the hard pad 111 at the portion above the recessed portion 11c3 in the side wall surface 11c2 (arrow B6).

[0064] The distal end 13h1 of the barb 13h is pressed into the hard pad 111 from the recess 11c3 of the side wall 11c2 (inserted state) (arrow B5). In addition, the distal end 13h1 of the barb 13h is pressed to the left in the X direction and firmly inserted into the hard pad 111 due to the above-mentioned reaction force.

[0065] The distal end 13g1 of the barb 13g is pressed into the hard pad 111 from the side wall surface 11c1 (inserted state) (arrow B4). The distal end 13g1 of the barb 13g is also pressed rightward in the X direction by the reaction force and firmly penetrates the hard pad 111.

[0066] The barb 13f is in a state where the distal end 13f1 is pressed into the hard pad 111 from the side wall surface 11c1 (inserted state) (arrow B3). However, the distal end 13f1 of the barb 13f is inserted into the hard pad 111 in a state where a part of the flat surface 13f2 is not pressed into the hard pad 111 and remains in the groove 11c.

[0067] Here, the decorative member 12 is fixed to the cushion pad 11 under tension so that the upper surface 11a or the front surface 11d of the cushion pad 11 is not wrinkled. Therefore, the resin clamp 13 to which the decorative member 12 is fixed is always under tension as indicated by the arrow B1. The resin clamp 13, which is always under tension as indicated by the arrow B1, generates a rotational moment (arrow B2) that moves the bottom end 13c of the base portion 13b toward the side wall surface 11c1 on the right side in the X direction.

[0068] If the resin clip having no barb portion is heated and plastically deformed in a state where the rotational moment acts as described above, there is a possibility that the resin clip will fall off from the groove portion 11 c.

[0069] However, the seat 1 involved in this embodiment is in the following state, that is, three barbs 13f~13h are provided at the above-mentioned position of the resin clamp 13, and the distal end portions 13f1, 13g1, 13h1 of each barb 13f~13h pierce the hard pad 111, so that even if the resin clamp 13 is heated, it is possible to suppress the resin clamp 13 from falling off from the groove portion 11c.

[0070] 6. Function of the flat surface portion 13f2 of the barb portion 13f in the resin holder 13

[0071] The barb portion 13f of the resin clamp 13 is provided with a flat surface portion 13f2. Figure 8 The function of the flat surface portion 13f2 will be described.

[0072] like Figure 8As shown, when the base portion 13b of the resin clamp 13 is inserted into the groove portion 11c, a portion of the flat portion 13f2 of the barb portion 13f is exposed to the inner side of the groove portion 11c from the side wall surface 11c1 of the groove portion 11c. The flat portion 13f2 is arranged to face the opening side of the groove portion 11c, and there is no member that becomes an obstacle above the flat portion 13f2. Therefore, when the operator observes the inside of the groove portion 11c from the opening of the groove portion 11c, the flat portion 13f2 can be visually identified. In addition, by confirming the distance D from the opening of the groove portion 11c to the flat portion 13f2, the operator can visually confirm whether the resin clamp 13 is inserted to the appropriate position in the groove portion 11c.

[0073] 7. Removal of the resin clamp 13

[0074] Regarding the seat 1, it is assumed that the end user wants to replace the garnish 12. In this case, when the garnish 12 is replaced, the resin clip 13 needs to be removed from the cushion pad 11. Fig. 9 A method of removing the resin clip 13 from the cushion pad 11 will be described.

[0075] If used Figure 3 As described above, the cushion pad 11 is provided with a connecting groove portion 11e which is continuous with the groove portion 11c. Fig. 9 As shown, when the resin holder 13 is to be removed from the cushion pad 11 , a rod-shaped tool (for example, a flat-blade screwdriver) is inserted into the communication groove portion 11 e from the distal end 500 a side (arrow C1 ).

[0076] After the distal end 500a of the tool 500 is inserted near the bottom of the connecting groove 11e, the distal end 500a of the tool 500 is pried (arrow C3) by moving toward the side wall surface 11c2 using the opening edge 11e1 of the connecting groove 11e indicated by arrow C2 as a fulcrum.

[0077] By prying the tool 500 as described above, the distal ends 13f1, 13g1 of the barbs 13f, 13g which have penetrated into the hard pad 111 from the side wall surface 11c1 are pulled out from the hard pad 111 (arrows C4, C5). Then, while the barbs 13f, 13g of the resin holder 13 are kept elastically deformed, the base 13b of the resin holder 13 is moved rightward in the X direction, and the resin holder 13 is taken out from the groove 11c together with the tool 500.

[0078] As described above, the removal of the resin holder is completed.

[0079] 8. Effect

[0080] In the structure in which the garnish 12 is fixed to the cushion pad 11 by inserting the resin clip 13 into the groove 11c of the cushion pad 11, the tension is Figure 7 The tension always acts on the decorative member fixing portion 13a of the resin clamp 13 in the X direction. In addition, in the resin clamp 13 subjected to the tension, a tension is generated that causes the bottom end 13c of the base portion 13b to move to the left. Figure 7 When the rotational moment is generated, if the resin holder 13 is heated, the resin holder 13 is easily softened and plastically deformed, and may fall off from the groove 11c.

[0081] However, the seat 1 involved in this embodiment is provided with three barbed portions 13f~13h in the resin clamp 13, and the distal ends 13f1, 13g1, and 13h1 of the barbed portions 13f~13h are in a state of piercing the hard pad 111 of the cushion pad 11. Therefore, even when the resin clamp 13 is heated, the barbed portions 13f~13h can be used to prevent the resin clamp 13 from falling off.

[0082] In addition, in Figure 7 When the rotational torque indicated by the arrow B2 acts on the resin clamp 13, the distal ends 13f1, 13g1 of the barbs 13f, 13g penetrate more deeply into the hard pad 111 of the buffer pad 11, thereby effectively preventing the resin clamp 13 from falling off.

[0083] In addition, the resin holder 13 is provided with a barb portion 13h which is continuous with the middle portion of the curved portion 13d in the longitudinal direction. Therefore, the reaction force maintains a state in which the force acts in a direction in which the distal end portion 13h1 of the barb portion 13h penetrates deeper into the hard pad 111 of the cushion pad 11 to the left in the X direction. Therefore, the posture of the base portion 13b of the resin holder 13 in the groove portion 11c of the cushion pad 11 is stably maintained, and the base portion 13b and the curved portion 13d are less likely to shake in the groove portion 11c.

[0084] Furthermore, in the seat 1 according to the present embodiment, the distal end portion 13g1 of the barb portion 13g and the distal end portion 13h1 of the barb portion 13h in the resin clamp 13 are arranged at the same height position in the depth direction of the groove portion 11c, thereby facilitating the maintenance of the posture of the base portion 13b in the groove portion 11c and the posture of the resin clamp 13 in an appropriate posture.

[0085] In the seat 1 according to the present embodiment, the distal ends 13f1, 13g1, 13h1 of the barbs 13f to 13h of the resin holder 13 are arranged so as to point to the back surface 11b side of the opening of the groove 11c in the cushion pad 11. Therefore, when a force is applied to cause the resin holder 13 to fall off from the groove 11c, the distal ends 13f1, 13g1, 13h1 of the barbs 13f to 13h penetrate deeper into the cushion pad 11. Therefore, in the seat 1, it is more advantageous to suppress the resin holder 13 from falling off from the groove 11c of the cushion pad 11.

[0086] In addition, the cushion pad 11 of the seat 1 according to the present embodiment is provided with the communicating groove 11e, so that by inserting a tool (for example, a rod-shaped tool such as a flat-blade screwdriver) 500 into the communicating groove 11e, the distal ends 13f1 and 13g1 of the barbs 13f and 13g are released from the state of being inserted into the cushion pad 11, and the resin clamp 13 can be removed from the groove 11c. Thus, when the end user wants to replace the decorative member 12, for example, it is possible to prevent the periphery of the groove 11c in the cushion pad 11 from being peeled off.

[0087] Here, in the seat 1 according to the present embodiment, the distal end portions 13f1, 13g1, and 13h1 of the barbs 13f to 13h in the resin clamp 13 are formed into a gradually tapered shape. Figure 7 As shown in the figures, the distal end shape of each distal end portion 13f1, 13g1, 13h1 is set to a shape with rounded corners (curved surface), so that when the resin clamp 13 is removed from the groove portion 11c using the tool 500, it can be ensured to be easy to pull out. In addition, when the resin clamp 13 is removed from the groove portion 11c, the side wall surfaces 11c1 and 11c2 around the groove portion 11c can be suppressed from being peeled off, and the decorative member 12 on the cushion pad 11 can be replaced while ensuring high maintainability.

[0088] Furthermore, when the distal ends 13f1, 13g1, 13h1 of the barbs 13f to 13h in the resin holder 13 are sharp, even if the tension generated by the decorative member 12 is Figure 7 Even when the rotational torque shown above acts on the resin holder 13 , the resin holder 13 can be prevented from being easily removed from the groove portion 11 c .

[0089] Furthermore, in the seat 1 according to the present embodiment, at least the groove portion 11 c and the surrounding area of ​​the cushion pad 11 are formed by a hard pad 111 made of a bead foam, so that the distal end portions 13f1, 13g1, 13h1 of the barbed portions 13f to 13h of the resin clamp 13 can be reliably inserted into the cushion pad 11.

[0090] In addition, the seat 1 according to the present embodiment uses a hard pad 111 made of beads with low recovery properties. Therefore, even if a hard pad 111 is used, Figure 6 and Figure 7 The barbed portions 13f to 13h with rounded corners at the distal ends can also reliably pierce the distal ends 13f1 , 13g1 , 13h1 into the hard pad 111 .

[0091] In the seat 1 according to the present embodiment, the barb 13f has the flat surface 13f2 near the distal end 13f1, so when the operator inserts the resin clip 13 into the groove 11c, the operator can confirm that the resin clip 13 is inserted to an appropriate depth based on the position of the flat surface 13f2 in the depth direction of the groove 11c. As a result, the seat 1 can prevent the resin clip 13 from being inserted into the groove 11c in an incomplete state, and can more effectively prevent the resin clip 13 from falling out of the groove 11c.

[0092] In addition, in the seat 1 involved in the present embodiment, the distal end 13i of the curved portion 13d in the resin clamp 13 is also formed in a manner pointing to the side wall surface 11c2, and is formed in a shape that gradually tapers from the vicinity of the distal end 13i to the distal end 13i. The distal end 13i is slightly pressed into the hard pad 111 of the cushion pad 11 from the side wall surface 11c2. Therefore, the resin clamp 13 inserted into the groove portion 11c can be suppressed from shaking in the groove portion 11c, and the posture of the resin clamp 13 can be maintained in a stable state.

[0093] As described above, the seat 1 according to the present embodiment can suppress the resin clip 13 from falling off the cushion pad 11 even when the resin clip 13 is softened by heat, and can stably maintain the fixing of the garnish 12 to the cushion pad 11 .

[0094] [Modifications]

[0095] In the above embodiment, although the distal end 13i of the bent portion 13d in the resin clamp 13 is pressed into the cushion pad 11 as an example, in the present invention, the distal end of the bent portion does not necessarily need to be pressed into the cushion pad. For example, the distal end of the bent portion may be spaced apart from the side wall surface of the groove portion.

[0096] In the above embodiment, the cushion pad 11 has the communicating groove portion 11 e in addition to the groove portion 11 c . However, in the present invention, the communicating groove portion is not necessarily required.

[0097] In the above embodiment, although the cushion pad 11 has a hard pad 111 made of bead foam, in the present invention, the hard pad does not necessarily need to be made of bead foam. In addition, the cushion pad has a laminated structure of a soft pad and a hard pad, which is not a necessary structure. For example, a single-layer cushion pad can be used, or a cushion pad with a laminated structure of three or more layers can be used.

[0098] In the above embodiment, although the flat surface 13f2 is provided on the barb 13f of the resin clamp 13, the flat surface 13f2 is not necessarily provided on the barb 13f in the present invention. Instead of providing the flat surface 13f2 on the barb 13f, a mark for confirming the insertion depth may be added to the base or the like.

[0099] In the above embodiment, the three barbs 13f to 13h are provided in the resin holder 13. However, in the present invention, four or more barbs may be provided in the resin holder.

[0100] [Summarize]

[0101] A seat according to a technical solution of the present invention includes a cushion pad, a decorative member, and a resin clamp. The cushion pad has a support area and other areas, the support area supports a seated person, and the other areas are areas other than the support area and are provided with a groove in the thickness direction. The decorative member has a covering area and an end edge, the covering area covers the support area in the cushion pad, and the end edge is arranged near the groove. The resin clamp is formed of a resin material, is used to fix the end edge of the decorative member, and fixes the decorative member and the cushion pad by being inserted into the groove.

[0102] In the seat involved in the present technical solution, the resin clamp includes a base portion, a decorative part fixing portion, a bent portion, a first barb portion, a second barb portion, and a third barb portion. The base portion is a portion inserted into the groove portion of the cushion pad. The decorative part fixing portion is formed to be continuous with the upper end of the base portion and extends from the continuous portion along the surface of the cushion pad in one of the width directions of the groove portion, that is, in the first direction, and fixes the end edge portion of the decorative part. The bent portion is a portion that is continuous with the base portion at one end and a free end at the other end, and has a shape that is bent in a manner of moving away from the base portion from the one end to the other end along the first direction, and is inserted into the groove portion together with the base portion in a state along the base portion, and has a flexible portion.

[0103] The first barb portion is a portion that is continuous between the one end and the other end of the curved portion, and extends from the continuous portion toward the first direction, and has a distal end portion that is tapered. The second barb portion is a portion that is continuous with the base portion, and extends from the continuous portion toward a second direction that is opposite to the first direction in the width direction of the groove portion, and has a distal end portion that is tapered. The third barb portion is a portion that is continuous with the base portion between a portion that is continuous with the second barb portion and a portion that is continuous with the decorative member fixing portion, and extends from the continuous portion toward the second direction, and has a distal end portion that is tapered.

[0104] Moreover, in the seat involved in the present technical solution, the base portion and the bent portion in the resin clamp are in a state where the base portion and the bent portion are inserted into the groove portion, and are subjected to a pressing force that causes the other end to approach the base portion, compared to a free state outside the groove portion.

[0105] In addition, in the seat involved in the present technical solution, in the groove portion of the cushion pad: the distal end portion of the first barb portion is pressed into the cushion pad from the wall surface of the groove portion located on the side of the first direction, i.e., the first side wall surface, based on the reaction force against the pressing force; and the distal end portions of the second barb portion and the third barb portion are pressed into the cushion pad from the wall surface of the groove portion located on the side of the second direction, i.e., the second side wall surface, based on the reaction force against the pressing force.

[0106] As described above, in the structure where the decorative member is fixed to the cushion by inserting the resin clamp into the groove, tension in the first direction always acts on the decorative member fixing portion. Moreover, in the resin clamp subjected to such tension, a rotational moment is generated in a direction in which the bottom end (the end inserted deep into the groove) in the base portion moves in the second direction. When this rotational moment is generated, if the resin clamp is heated, the resin clamp may fall off from the groove.

[0107] However, in the seat involved in the above technical solution, the resin clamp is provided with the first to third barb portions, and the distal ends of the barb portions are in a state of piercing into the cushioning pad (being pressed in). Therefore, even when the resin clamp is heated, the barb portions are utilized to prevent the resin clamp from falling off.

[0108] Furthermore, when the above-mentioned rotational torque acts on the resin holder, the distal ends of the second barb portion and the third barb portion penetrate deeper into the buffer pad, thereby facilitating effective suppression of the resin holder from falling off.

[0109] In addition, the resin holder is provided with a first barb portion continuous with a portion between one end and the other end of the curved portion, so that the reaction force against the pressing force maintains a state in which a force in a direction in which the distal end of the first barb portion penetrates deeper into the cushion pad in the first direction continues to act on the resin holder. Therefore, the posture of the base portion in the groove portion is stably maintained, and the base portion and the curved portion are less likely to shake in the groove portion.

[0110] In the seat involved in the above technical solution, the distal end portion of the first barb portion and the distal end portion of the second barb portion may be arranged so that the distal ends thereof are at the same height position in the groove depth direction of the groove portion.

[0111] In the seat involved in the above technical solution, the distal end portion of the first barb portion and the distal end portion of the second barb portion in the resin clamp are arranged in a manner that they are at the same height position in the depth direction of the groove portion. Therefore, it is beneficial to maintain the posture of the base portion in the groove portion in an appropriate posture, and further maintain the posture of the resin clamp in the groove portion in an appropriate posture.

[0112] In the seat involved in the above technical solution, the first barb portion, the second barb portion and the third barb portion may be arranged so that the distal end portion of each barb portion points to the surface side of the opening of the groove portion in the cushion.

[0113] In the seat according to the above technical solution, the distal end of each of the first to third barbs in the resin clamp is arranged to point to the surface of the side of the opening of the groove in the cushion pad, so that when a force is applied to cause the resin clamp to fall off from the groove, the distal end of each barb penetrates deeper into the cushion pad. Therefore, the seat according to the above technical solution is more conducive to preventing the resin clamp from falling off from the groove of the cushion pad.

[0114] In the seat involved in the above technical solution, it can also be that: the groove portion of the buffer pad and the resin clamp are formed to extend along a fourth direction orthogonal to the insertion direction of the base portion, that is, the third direction and the first direction, and the buffer pad also has a connecting groove portion, and the connecting groove portion is arranged to be continuous with the groove portion in an area of ​​a portion in the fourth direction in the groove portion and in an area in the third direction up to the portion where the second barb portion is located; and, is recessed from the second side wall surface.

[0115] In the seat involved in the above technical solution, the cushion pad is provided with a connecting groove portion, so that by inserting a tool (for example, a rod-shaped tool such as a flat-blade screwdriver) into the connecting groove portion, the second and third barbs are released from the cushion pad, thereby enabling the resin clamp to be removed from the groove portion. Thus, when the end user wants to replace the decorative part, for example, it is possible to prevent the periphery of the groove portion in the cushion pad from being peeled off.

[0116] In the seat according to the above technical solution, the cushion pad may include a portion formed of bead foam, and the groove portion and its surrounding area may be provided in the portion formed of bead foam.

[0117] In the seat according to the above aspect, at least the groove portion and its surrounding portion are provided in the portion formed of the bead foam body, so that the distal end portions of the barbs of the resin clip can be reliably inserted into the cushion pad.

[0118] In the seat according to the above technical solution, the third barb portion may include a planar portion, which is a portion near the distal end portion and intersects with a groove depth direction of the groove portion and faces an opening side of the groove portion.

[0119] In the seat according to the above technical solution, the third barb has a flat surface near the distal end portion, so when the operator inserts the resin clamp into the groove, the operator can confirm that the resin clamp is inserted to an appropriate depth based on the position of the flat surface in the depth direction of the groove. As a result, the seat according to the above technical solution can prevent the resin clamp from being inserted into the groove in an incomplete state and can more effectively prevent the resin clamp from falling out of the groove.

[0120] In the seat involved in the above technical solution, it can also be that: the bent portion is formed so that the other end points to the first direction, and is formed into a shape that gradually becomes thinner from the vicinity of the other end to the other end, and the other end of the bent portion is pressed into the cushioning pad from the first side wall surface.

[0121] In the seat involved in the above technical solution, the other end of the resin clamp from the bent portion is formed into a shape that gradually becomes thinner from the vicinity of the other end to the other end, and the other end is pressed into the cushioning pad from the first side wall surface. Therefore, the resin clamp inserted into the groove portion can be prevented from shaking in the groove portion and the posture of the resin clamp can be maintained in a stable state.

[0122] As described above, the seat according to each of the above-mentioned aspects can suppress the resin clip from falling off from the cushion pad even if the resin clip is heated, and can stably maintain the fixing of the garnish to the cushion pad.
