[0025] Hereinafter, a vehicle seat surface according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0026] Furthermore, in this specification, "front-to-back direction" refers to the direction that extends in the same direction as the end edge 30a of the skin material 30 described later, and is designated as the X-axis direction.

[0027] Additionally, "vertical direction" refers to the insertion and removal direction of the skin material fastener 40 relative to the locking hole 11 of the plate 10 (described later). Within the vertical direction, the direction in which the skin material fastener 40 is inserted into the locking hole 11 is called the insertion direction, and the direction in which the skin material fastener 40 is removed from the locking hole 11 is called the removal direction. The vertical direction is the Z-axis direction, orthogonal to the X-axis direction, and coincides with the thickness direction of the cushioning material 20 (described later).

[0028] Additionally, the "left-right direction" refers to the direction that intersects with the X-axis (forward / backward) and the Z-axis (upward / downward), and is designated as the Y-axis direction. The direction parallel to this left-right direction is also called the lateral direction.

[0029] Figure 1 This is a schematic diagram showing a vehicle seat surface that uses fasteners made of skin material.

[0030] The seat 1 for vehicles has a plate 10, a cushioning material 20 stacked on the plate 10, a skin material 30 covering the surface of the cushioning material 20, and a skin material fastener 40 for fixing the skin material 30 covering the cushioning material 20 to the plate 10.

[0031] The upper surface of the seat surface 1 is formed by laminating a cushioning material 20, which is cut into a shape slightly larger than the plate 10 and has a specified thickness, on the surface 10a of the plate 10.

[0032] The inner surface 10b of the plate 10 becomes the lower surface of the seat 1, and is provided with a plurality of locking holes 11 for mounting the skin material fasteners 40.

[0033] The locking hole 11 is a through hole that penetrates the plate 10 in the thickness direction and is formed into a cylindrical shape. In addition, the locking hole 11 can be any shape that allows the skin material fastener 40 to pass through and be fixed, and is not limited to a cylindrical hole.

[0034] The skin material 30 overlaps the surface of the cushioning material 20 provided on the surface 10a of the plate. A locking end member 31 that can be installed on the skin material fastener 40 is integrally provided at the end edge 30a of the skin material 30.

[0035] The end edge 30a of the skin material 30 can be detachably held to the skin material fastener 40 via the locking end member 31.

[0036] The locking end member 31 is molded from synthetic resin, for example, with a cross-sectional shape approximately V-shaped, and is formed along the length of the end edge 30a. The locking end member 31 is disposed along the end edge 30a of the skin material 30 by being embedded in the end edge 30a formed in the skin material 30.

[0037] The cross-sectional shape of the locking end member 31 in the plane (YZ plane) orthogonal to the end edge 30a is formed into a generally arrowhead shape by the base end portion 31a formed on the side of the end edge 30a of the skin material 30, a pair of inclined portions 31b, 31b inclined from the base end portion 31a toward the top end direction, and the top end portion 31c which is generally parallel to the base end portion 31a.

[0038] (Skin material fasteners)

[0039] Next, based on Figures 2-8 The specific structure of the skin material fastener 40 is described. Figure 2 This is a diagram showing the deformed shape of the insertion part of the fastener in the skin material. Figure 3 This is a rear-view perspective view of the fasteners for the skin material. Figure 4 This is a front-view perspective view of the fasteners for the skin material. Figure 5 This is the front view of the fasteners for the skin material. Figure 6 This is a side view of the fastener made of skin material. Figure 7 This is a top view of the fasteners for the skin material. Figure 8 This is a bottom view of the fasteners made of skin material.

[0040] The skin material fastener 40 has a clamping head 50 and a locking part 60, and is integrally formed from a synthetic resin or the like that that can be elastically deformed.

[0041] The clamp head 50 detachably mounts the end edge 30a of the skin material 30 by retaining (locking) the locking end member 31. The locking part 60 is detachably mounted to the plate 10 by inserting into the locking hole 11. The skin material 30 covering the cushioning material 20 can be mounted to the side of the plate 10 using the skin material fastener 40.

[0042] The clamp head 50 has a retaining part 51 for holding the locking end member 31 in a removable manner, an abutting surface 56 that abuts against the plate 10, and an insertion pressing surface 57 used when inserting the skin material fastener 40 into the locking hole 11. The clamp head 50 is formed in a box shape.

[0043] The retaining part 51 forms a receiving part 55 for storing the locking end member 31 by means of a pair of clamping parts 52, 52 provided in such a way as to clamp the arrow-shaped locking end member 31 in the vertical direction. Each clamping part 52, 52 has a first locking piece 53 and a second locking piece 54.

[0044] A pair of clamping parts 52, 52 have opposing clamping surfaces 52a, 52a and are formed to be elastically deformable in the direction of separation.

[0045] A pair of clamping surfaces 52a, 52a are inclined surfaces that are inclined from the base end to the top end in a direction that separates them from each other. Their base ends are connected to each other, while their top ends are open to each other.

[0046] Thus, the storage portion 55 is formed in a wedge shape, extending in the front-rear direction of the locking end member 31 and opening on the left-right direction (top end side) where the skin material 30 connects to the locking end member 31. For more information on this structure, please refer to... Figure 1 and Figure 2 .

[0047] The first locking piece 53 is respectively provided at the top end of a pair of clamping surfaces 52a, and is used to lock the base end 31a of the locking end member 31 stored in the storage part 55.

[0048] A pair of first locking tabs 53, 53 protrude toward each other in a direction close to each other (Z-axis) and extend along a front-back (X-axis) direction. A space is formed between the pair of first locking tabs 53, 53 for the end edge 30a of the skin material 30 to pass through.

[0049] Thus, the locking end member 31 can be stored in the storage part 55 from the left or right side of the clamp head 50 (holding part 51).

[0050] The second locking piece 54 is respectively disposed at the center of the front-back direction and the left-right direction of the pair of clamping surfaces 52a.

[0051] The pair of second locking tabs 54, 54 extend in the same direction as the first locking tab 53, approaching each other. The pair of second locking tabs 54, 54 clamp the inclined portion 31b of the locking end member 31 housed in the storage portion 55.

[0052] Alternatively, a groove (not shown) for locking the second locking piece 54 may be formed in the inclined portion 31b of the locking end member 31.

[0053] In the above example, the clamp head 50 is a so-called lifting rod method in which the clamping end member 31 provided at the end of the skin material 30 can be easily attached and detached to clamp (hold). However, it is not limited to the above structure as long as the skin material 30 can be connected to the clamp head 50.

[0054] In addition, the clamp head 50 does not need to be a structure that allows the end of the skin material 30 to be easily attached and detached; it can also be a structure that directly fixes the end of the skin material 30 by sewing, gluing, or other means.

[0055] The abutment surface 56 is the side of the clamping portion 52 near the plate 10 opposite to the side where the first locking piece 53 and the second locking piece 54 are formed. When the skin material fastener 40 is inserted into the locking hole 11, the abutment surface 56 abuts against the plate 10. In other words, the abutment surface 56 is a plane formed at the end of the box-shaped clamping head 50 in the insertion (Z-axis) direction.

[0056] The insertion pressing surface 57 is a pressing surface formed at the end of the box-shaped clamp head 50 on the disengagement side in the insertion / removal (Z-axis) direction. The insertion pressing surface 57 is an XY plane that is approximately orthogonal to the insertion / removal direction, and has a curved portion 57a ​​that bends in the left-right (Y-axis) direction toward the disengagement direction as it moves toward the locking portion 60.

[0057] like Figure 1 and Figure 2 As shown, the curved portion 57a ​​is formed such that it protrudes towards the locking portion 60 from the back surface 58 of the retaining portion 51. Furthermore, the back surface 58 of the retaining portion 51 is formed continuously in a straight line from the inner surface of the first portion 61a of the insertion portion 61, which will be described later.

[0058] The locking part 60 has: a letter V-shaped insertion part 61 that is elastically deformable; a stepped part 62 for locking the insertion part 61 inserted into the locking hole 11; a disassembly operation part 63 for operating the elastic deformation of the insertion part 61; and a limiting piece 64 for limiting the elastic deformation of the insertion part 61.

[0059] The insertion part 61 has a first part 61a extending from the clamp head 50 in the insertion direction, a bent part 61b formed by bending the insertion end of the first part 61a into a letter V shape, and a second part 61c extending from the bent part 61b toward the disengagement direction in an inclined direction.

[0060] A clamp head 50 is connected to the detachment side end of part 1 61a, and a disassembly operation part 63 is connected to the detachment side end of part 2 61c.

[0061] The step portion 62 is formed at the end of the second part 61c on the other side of the insertion portion 61, and is formed on the left-right outer side of the second part 61c in such a way that the insertion portion 61 inserted into the locking hole 11 can be locked in the locking hole 11.

[0062] The disassembly operation section 63 is provided at the disengagement side end of the second part 61c that constitutes the insertion part 61. The disassembly operation section 63 has a disassembly operation surface 63a for pressing the second part 61c toward the first part 61a and a limiting surface 63b for preventing the insertion part 61 from deforming to a predetermined degree or more.

[0063] When the disassembly operation surface 63a is pressed, the second part 61c smoothly and elastically deforms in a manner close to the first part 61a, with the bent part 61b as the fulcrum. In other words, it elastically deforms in the direction where the width of the V-shaped insertion part 61 decreases in the left-right (Y-axis) direction.

[0064] The limiting piece 64 is an arc-shaped protrusion provided on the upper part of the back surface 58 of the retaining part 51. When the disassembly operation surface 63a is pressed, the limiting piece 64 abuts against the limiting surface 63b of the disassembly operation part 63, thereby limiting further deformation of the insertion part 61. The deformation limit position of the disassembly operation part 63 can be adjusted by the size of the limiting piece 64.

[0065] Based on the above, the skin material fastener 40 can be switched to the initial state where no elastic force is applied to the insertion part 61. Figure 2 1) By inserting the skin material fastener 40 into the locking hole 11, the V-shaped insertion part 61 is elastically deformed in the narrowing direction, thereby locking the stepped part 62 into the locking state of the locking hole 11. Figure 2 2), and the disassembly operation part 63 is pressed into the disassembly state where it abuts against the limiting piece 64. Figure 2 3).

[0066] (Function and Effect)

[0067] based on Figure 1 and Figure 2 The method of using skin material fasteners 40 to tighten cushioning material 20 and skin material 30 onto plate 10 to form seat surface 1 will be described.

[0068] First, skin material fasteners 40 are installed at any position on the locking end member 31 mounted on the skin material 30. Multiple skin material fasteners 40 are installed at predetermined intervals along the length of the locking end member 31, and each skin material fastener 40 is configured to match the position of the locking hole 11 of the plate 10.

[0069] At this time, by inserting the locking end member 31 into the receiving part 55 of the clamp head 50, the skin material fastener 40 is installed on the locking end member 31.

[0070] Specifically, since the pair of clamping portions 52, 52 constituting the storage portion 55 can elastically deform in a direction of separation, the locking end member 31 can be pressed into the storage portion 55 through the gap formed between the pair of first locking pieces 53, 53. After the locking end member 31 is stored in the storage portion 55, the elastic deformation of the clamping portions 52, 52 returns to normal. Therefore, the locking end member 31 is fitted into the storage portion 55 without coming out, thanks to the pair of first locking pieces 53, 53 and second locking pieces 54, 54.

[0071] Next, the skin material 30, to which the skin material fastener 40 is installed, is overlapped on the cushioning material 20, and the end edge 30a of the skin material 30 is wound around the end edge of the plate 10 and overlapped on the inside 10b of the plate 10. Thus, the cushioning material 20 is pressed against the surface 10a of the plate and fixed in place.

[0072] Next, the skin material fastener 40 of the end edge 30a of the skin material 30 overlapping the inner 10b of the plate is inserted into the locking hole 11 from the inner 10b of the plate, thereby fixing it to the plate 10 (see reference). Figure 1 ).

[0073] At this time, the insertion pressing surface 57 functions as a pressing (operating) surface for smoothly and efficiently pressing the skin material fastener 40 toward the insertion direction that locks into the locking hole 11, thus enabling the skin material fastener 40 to be smoothly pressed into the locking hole 11.

[0074] Furthermore, the curved portion 57a ​​formed at the end of the insertion pressing surface 57 protrudes towards the locking portion 60 in the left-right (Y-axis) direction than the back surface 58 of the holding portion 51, and is thus positioned on the extension line of the first part 61a constituting the insertion portion 61 in the insertion-removal (Z-axis) direction. Therefore, the pressing force applied by the curved portion 57a ​​can be transmitted more efficiently to the top end (bent portion 61b) of the insertion portion 61.

[0075] The operation of the locking part 60 when the skin material fastener 40 is inserted into the locking hole 11 will be explained in detail. First, when the insertion part 61 is inserted into the locking hole 11, the second part 61c of the insertion part 61 is pressed by the locking hole 11 and elastically deforms in a direction closer to the first part 61a. At this time, the greater the insertion depth into the locking hole 11, the greater the deformation of the insertion part 61.

[0076] Next, when the step portion 62 formed in the second part 61c passes the locking hole 11, the skin material fastener 40 is locked in place. Figure 2 2) The stepped portion 62 is hooked onto the locking hole 11. Thus, the skin material fastener 40 is securely fixed to the plate 10. For details on this structure, please refer to... Figure 1 .

[0077] At this time, when the step portion 62 passes the locking hole 11, the elastic deformation of the insertion portion 61 will slightly recover and produce a clicking sensation, so the operator can feel that the skin material fastener 40 is fixed to the plate 10.

[0078] For the skin material fastener 40 fixed to the plate 10 via the locking hole 11, such as Figure 1 As shown, the contact surface 56 of the clamp head 50 abuts against the inside 10b of the plate, the first part 61a of the insertion part 61 abuts against the left and right sides of the locking hole 11, and the stepped part 62 abuts against the other left and right sides of the locking hole 11. Thus, the skin material fastener 40 fixed to the locking hole 11 is firmly fixed to the side of the plate 10 without wobbling.

[0079] In other words, even when the skin material 30 is pulled and a shear force is applied to the skin material fastener 40 which is fixed to the plate 10 in a direction parallel to the plate 10, the skin material fastener 40 will not tilt, but will remain stable.

[0080] By removing the skin material fastener 40, which is fixed to the plate 10 via the locking hole 11, from the plate 10, it is also possible to easily perform maintenance such as re-tightening and cleaning of the skin material 30, as well as changes in its installation position.

[0081] according to Figure 2 The disassembly method for removing the skin material fastener 40 from the plate 10 is explained.

[0082] For the skin material fastener 40 installed on the plate 10, the insertion part 61 is elastically deformed by pressing the disassembly operation surface 63a, so that the left and right width of the insertion part 61 is smaller than the locking hole 11.

[0083] Specifically, when the disassembly operation surface 63a is pressed, the insertion part 61 elastically deforms in such a way that the second part 61c approaches the first part 61a. Figure 2 2→ Figure 2 3). Thus, the insertion part 61 can be smoothly pulled out (disassembled) from the locking hole 11 without resistance.

[0084] At this time, as Figure 2 As shown, the skin material fastener 40 can be held by pinching the insertion pressing surface 57 (bent portion 57a) of the clamp head 50 and the disassembly operation surface 63a of the locking portion 60. Thus, the operator can simultaneously hold the skin material fastener 40 and switch to the disassembly state with one hand, thereby smoothly removing the skin material fastener 40 from the plate 10.

[0085] Furthermore, the present invention is not limited to the above-described embodiments, but can be appropriately modified or improved within the scope of implementation.

[0086] As stated above, the following matters are disclosed in this specification.
