When attaching an ornament to an upholstery, there are cases where the ornament is attached so as not to protrude from the surface of the upholstery. However, in this case, if the skin material is composed of a plurality of layers and formed relatively thick, wrinkles are likely to occur in the skin material near the periphery of the ornament, and the appearance quality around the ornament is impaired. There is a risk that

Accordingly, it is an object of the present invention to provide a mounting structure for an ornament that can suppress the occurrence of wrinkles in the skin material near the periphery of the ornament even when the ornament is attached so as not to protrude from the surface of the skin material. With the goal.

In order to achieve the above object, the mounting structure for an ornament according to claim 1 of the present invention comprises a main body portion having a design surface and a fixed portion protruding from the back surface of the main body portion. , a through hole through which the fixed portion is inserted, and a slit portion that continues from the through hole toward a portion where the peripheral edge portion of the main body portion is arranged; A recess having a depth equal to or greater than the thickness of the main body and a through hole through which the fixed portion is inserted are provided. and a back plate sandwiching a part of the body with the main body.

According to the first aspect of the invention, the main body of the accessory and the back plate sandwich a part of the skin material, that is, the main body of the accessory is accommodated in the recess of the back plate together with a part of the skin material. In this state, the ornament is attached to the upholstery material. At this time, since the depth of the concave portion of the back plate is set to be greater than or equal to the thickness of the main body, the design surface of the ornament does not protrude from the surface of the upholstery material. Further, the skin material is formed with a slit continuous from the through-hole through which the fixed part is inserted to the part where the peripheral part of the main body of the accessory is arranged. Therefore, even if the skin material is formed relatively thick, the pressure applied to the skin material is relieved by the widening of the slit portion, and the occurrence of wrinkles in the skin material near the peripheral edge of the ornament is suppressed.

In addition, the attachment structure for an ornament according to claim 2 is the attachment structure for an ornament according to claim 1, wherein a fixing member capable of fixing the portion to be fixed inserted through the through hole of the back plate is provided. It has

According to the second aspect of the invention, the fixed portion inserted through the through hole of the back plate is fixed by the fixing member. Therefore, it is possible to more reliably prevent the accessory from coming off the skin material (back plate).

Further, the attachment structure for an ornament described in claim 3 is the attachment structure for an ornament according to claim 1 or claim 2, wherein the main body has an arc-shaped corner when viewed from the thickness direction. It is formed in a substantially rectangular shape having a portion and is made of a resin material having a parting line in a substantially central portion in the thickness direction, and when viewed from a direction perpendicular to the thickness direction of the main body portion, at least the corner portions of the party are formed. The back surface side from the ground line is formed in an arc shape.

According to the third aspect of the invention, the main body of the ornament is formed in a substantially rectangular shape with arcuate corners when viewed from the thickness direction, and when viewed from the direction orthogonal to the thickness direction At least the back side from the parting line at the corner portion is formed in an arc shape. Therefore, at least at the corner portion, compared to the case where the peripheral edge portion on the back side from the parting line and the back surface are formed in a shape in which the back surface intersects at a substantially right angle, the corner portion of the main body portion exists near the corner portion. The pressing force for pushing the skin material into the recess is reduced. As a result, when the main body of the ornament is accommodated in the recess of the back plate together with part of the skin material, wrinkling of the skin material in the vicinity of the peripheral edge of the ornament is effectively suppressed. In addition, in the appearance of the design surface of the ornament, only the parting line is visible at most. Therefore, there is no fear that the design of the decorative article will be spoiled by the shape of the back side from the parting line.

In addition, the mounting structure for a decorative device according to claim 4 is the mounting structure for a decorative device according to claim 3, wherein the parting line at the corner portion is formed on the back surface of the main body portion at the corner portion. A ridgeline portion having a curvature smaller than the curvature is formed.

According to the fourth aspect of the invention, the ridgeline portion having a smaller curvature than the curvature of the parting line at the corner portion is formed on the back surface of the corner portion of the main body portion of the accessory. Therefore, compared to the case where the back surface of the corner portion is formed with a ridgeline portion having a curvature larger than the curvature of the parting line of the corner portion, the curvature of the back surface side of the corner portion becomes gentler, and the main body portion is curved. The corner portion further reduces the pressing force that pushes the skin material present in the vicinity of the corner portion into the recess. As a result, when the main body of the ornament is housed in the recess of the back plate together with part of the skin material, wrinkling of the skin material near the periphery of the ornament can be more effectively suppressed. In addition, in the appearance of the design surface of the ornament, only the parting line is visible at most. Therefore, there is no fear that the design of the ornament will be spoiled by the ridge line.

As described above, according to the present invention, even if the ornament is attached so as not to protrude from the surface of the upholstery, it is possible to suppress the occurrence of wrinkles in the upholstery near the periphery of the ornament. .

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. As an example, the ornament 30 according to the present embodiment is attached to the upholstery material 12 of a vehicle seat (not shown). Therefore, for convenience of explanation, the arrow UP shown in each drawing is the upward direction of the vehicle seat, the arrow FR is the front direction of the vehicle seat, and the arrow RH is the right direction of the vehicle seat. That is, in the following description, when the directions of up and down, front and rear, left and right are indicated without any particular description, they indicate the up and down, front and rear, and left and right of the vehicle seat.

As shown in FIGS. 1 to 5, the mounting structure 10 according to the present embodiment includes a skin material 12 of a vehicle seat and a resin-made structure that is attached to the skin material 12 by sandwiching the skin material 12. A decorative device 30 and a back plate 20 made of resin are provided. The back plate 20 is arranged on the back side of the upholstery material 12 , and the ornament 30 is arranged on the front surface of the upholstery material 12 . As an example, the ornament 30 is provided on the right side of the vehicle seat.

The accessory 30 has a substantially rectangular plate-shaped body portion 32 whose longitudinal direction is the front-rear direction. The surface of the body portion 32 is a design surface 34 on which logos, patterns, etc. are displayed. , are formed in an arc shape (see FIG. 3).

In addition, a pair of substantially cylindrical protrusions 36 as fixed portions are provided on the planar rear surface 32C (see FIGS. 5, 7, and 8) of the main body 32 of the accessory 30. are spaced apart in the longitudinal direction of the main body 32 and integrally protrude so as to extend along the thickness direction of the main body 32 (see FIGS. 2 and 5).

On the rear surface 32C of the main body 32 and behind the central portion in the longitudinal direction, there is a substantially rectangular flat plate-shaped positioning protrusion 38 whose longitudinal direction is the longitudinal direction and whose normal direction is the vertical direction. , are integrally projected so as to extend along the thickness direction of the body portion 32 (see FIGS. 2, 4, and 5).

The positioning protrusion 38 is for positioning the accessory 30 so that it is not placed upside down, and is shifted to one longitudinal direction side (front side or rear side) with respect to the longitudinal direction central portion of the main body portion 32 . It is protruded. Therefore, contrary to the illustrated one, it may protrude from the central portion of the main body portion 32 in the longitudinal direction.

Further, as shown in FIG. 5, a plurality (for example, five) of substantially conical shapes are provided at a predetermined interval in the longitudinal direction at a substantially central portion in the vertical direction of the back surface 32C of the main body portion 32 of the accessory 30. A small protrusion 37 is provided. Each of the small projections 37 bites into the surface of the skin material 12 when the accessory 30 (main body part 32) is attached to the back plate 20 with the skin material 12 interposed therebetween, and the skin material 12 is attached to the main body part 32. It is designed to press toward the back plate 20 along the thickness direction.

As shown in FIGS. 2 to 5, the back plate 20 has a substantially rectangular bathtub-shaped main body portion 22 whose longitudinal direction is the front-rear direction and which is one size larger than the main body portion 32 of the accessory 30. . That is, the surface side of the main body portion 22 has a depth equal to or greater than the thickness of the main body portion 32 of the accessory 30, preferably equal to or greater than the sum of the thickness of the main body portion 32 and the thickness of the upholstery material 12. A concave portion 24 is formed that can accommodate a portion of the body portion 32 and the skin material 12 .

Therefore, the design surface 34 of the ornament 30 does not protrude from the peripheral edge 23 of the main body 22 when the main body 32 of the ornament 30 is accommodated in the recess 24 of the back plate 20 together with a part of the skin material 12.例文帳に追加(so as to be flush with the peripheral edge portion 23 even in the most projected state). In other words, the design surface 34 of the ornament 30 does not protrude from the surface of the upholstery material 12 (see FIG. 5).

In addition, a pair of substantially circular through holes 26 are formed in the body portion 22 (recessed portion 24) of the back plate 20 so as to correspond to each projection portion 36 of the ornament 30 (so that each projection portion 36 can be inserted). ), and are spaced apart in the longitudinal direction of the body portion 22 . On the rear surface of the body portion 22, a metal push nut 40 as a fixing member is fitted to each protrusion 36 inserted through each through hole 26. As shown in FIG.

As shown in FIGS. 2 and 4, each push nut 40 has an annular plate-shaped body portion 42 with a substantially circular opening 46 formed in the center. , a plurality of (for example, six) slits 48 extending radially from the opening 46 are formed at regular intervals in the circumferential direction.

In other words, the body portion 42 of each push nut 40 is formed with a plurality of (for example, six) substantially isosceles trapezoidal claw portions 44 at regular intervals in the circumferential direction. A substantially circular opening 46 is formed (see FIG. 4). The inner diameter of the opening 46 is made smaller than the outer diameter of the protrusion 36 .

Therefore, when the push nut 40 is fitted into the protrusion 36 inserted through the through hole 26 (when the protrusion 36 is inserted into the opening 46), the claws 44 expand downstream in the insertion direction of the protrusion 36. It is elastically deformed so as to open, and the outer peripheral surface of the protruding portion 36 is held by the restoring force of each claw portion 44 . As a result, even if the protrusion 36 is pulled in the direction opposite to the insertion direction, the tips (edge portions) of the claws 44 are relatively hooked on the outer peripheral surface of the protrusion 36 , and the protrusion 36 is pulled into the opening 46 . It is configured so that it cannot be pulled out (see FIG. 5).

Further, as shown in FIGS. 2, 4, and 5, in the body portion 22 (recessed portion 24) of the back plate 20 and rearward of the central portion in the longitudinal direction, there is an approximation in which the longitudinal direction is the longitudinal direction. A rectangular through hole 28 is formed. In other words, the through hole 28 is formed corresponding to the positioning protrusion 38, and is formed to have a size that allows the positioning protrusion 38 to be inserted therein. By inserting the positioning projection 38 into the through-hole 28, the accessory 30 is positioned so as not to be placed upside down.

As shown in FIGS. 1 and 2, the upholstery material 12 to which the ornament 30 is attached is not composed of one layer but of multiple layers. To give a specific example, the skin material 12 is based on a slab urethane 12A, which is a sponge body with a thickness of several mm. and a thin cloth-like back base cloth 12C adhered to the three-layer structure.

Further, as shown in FIG. 2, an area 14 (indicated by imaginary line K) for attaching the ornament 30 is defined on the surface of the upholstery material 12, and a pair of projections are provided in the area 14. A pair of substantially circular through-holes 16 through which the portion 36 is inserted is formed. The skin material 12 has a pair of slits 17 extending from each through-hole 16 toward a portion where the peripheral portion (specifically, each corner portion 33) of the main body portion 32 of the ornament 30 is arranged. formed.

Specifically, in the area 14, the front upper slit portion 17Fu is continuously formed from the through hole 16F on the front side in the longitudinal direction to the vicinity of the portion where the upper front corner portion 33Fu is arranged. A small hole portion 17Fs having a diameter smaller than that of the through hole 16F is continuously formed at the upper end portion (the portion farthest from the through hole 16F) of the front upper slit portion 17Fu.

In the area 14, a front lower slit portion 17Fd is continuously formed from the through hole 16F on the front side in the longitudinal direction to the vicinity of the portion where the corner portion 33Fd on the front lower side is arranged. A small hole portion 17Fs having a diameter smaller than that of the through hole 16F is continuously formed at the lower end portion of the portion 17Fd (the portion farthest from the through hole 16F).

Similarly, in the area 14, the rear upper slit portion 17Ru is continuously formed from the through hole 16R on the rear side in the longitudinal direction to the vicinity of the portion where the corner portion 33Ru on the rear upper side is arranged. A small hole portion 17Rs having a diameter smaller than that of the through hole 16R is continuously formed at the upper end portion (the portion farthest from the through hole 16R) of the portion 17Ru.

In the area 14, a rear lower slit portion 17Rd is continuously formed from the through hole 16R on the rear side in the longitudinal direction to the vicinity of the portion where the corner portion 33Rd on the rear lower side is arranged. A small hole portion 17Rs having a smaller diameter than the through hole 16R is continuously formed at the lower end portion of the portion 17Rd (the portion farthest from the through hole 16R).

The small holes 17Fs and 17Rs are for preventing the skin material 12 from breaking any further. Further, a through hole 18 through which the positioning projection 38 is inserted is formed in the area 14 . The through hole 18 is formed in a substantially rectangular shape with the longitudinal direction being the longitudinal direction corresponding to the positioning projection 38, and is formed in a size that allows the positioning projection 38 to be inserted therein.

Further, as shown in FIGS. 6 to 8, a parting line PL is formed in a substantially central portion in the thickness direction of the main body portion 32 of the accessory 30, projecting in a direction orthogonal to the thickness direction. The parting line PL is formed by the boundary between the core and the cavity of the molding die (not shown).

Then, as shown in FIG. 7, the peripheral portion (at least each corner portion 33) of the main body portion 32 is arcuate from the parting line PL toward the rear surface 32C when viewed from the direction orthogonal to the thickness direction of the main body portion 32. The surface (design surface 34) side from the parting line PL is formed in a straight line. In other words, the arc-shaped peripheral edge portion 32B is formed on the back surface 32C side from the parting line PL, and the linear (tapered) peripheral edge portion 32A is formed on the front surface (design surface 34) side from the parting line PL.

Further, as shown in FIG. 8, each corner portion 33 has a rear surface 32C of the main body portion 32, more specifically, a boundary portion between an arc-shaped peripheral edge portion 32B and a planar rear surface 32C at each corner portion 33. A ridgeline portion 35 having a smaller curvature than the curvature of the parting line PL in the portion 33 is formed. In other words, a ridge line portion 35 having a radius of curvature larger than the radius of curvature of the parting line PL at each corner portion 33 is formed at each corner portion 33 at the boundary portion between the arc-shaped peripheral edge portion 32B and the back surface 32C. ing.

Next, the operation of the mounting structure 10 for the accessory 30 according to this embodiment configured as described above will be described.

As shown in FIGS. 1 to 5, a portion of the skin material 12 is sandwiched between the main body 32 of the accessory 30 and the back plate 20; The ornament 30 is attached to the upholstery 12 by being accommodated in the concave portion 24 of the back plate 20 together with the ornament 30 . The depth of the concave portion 24 of the back plate 20 is greater than or equal to the thickness of the body portion 32 , preferably greater than or equal to the sum of the thickness of the body portion 32 and the thickness of the skin material 12 . Therefore, the design surface 34 of the ornament 30 does not protrude from the surface of the upholstery 12 .

In addition, the skin material 12 has a slit portion 17 continuous from the through hole 16 through which the protrusion 36 is inserted to the portion where the peripheral edge portion (specifically, each corner portion 33) of the main body portion 32 of the ornament 30 is arranged. is formed. Therefore, even if the skin material 12 is formed relatively thick (for example, having a three-layer structure as described above), the pressure applied to the skin material 12 can be relieved by widening the slit portion 17 . Therefore, it is possible to suppress the occurrence of wrinkles in the upholstery material 12 near the periphery of the accessory 30 (specifically, each corner 33).

In addition, since a small hole portion 17Fs and a small hole portion 17Rs are formed at the end of each slit portion 17 (the portion farthest from the through hole 16), when the projection portion 36 is inserted into the through hole 16, Even if the skin material 12 is distorted so that the slit part 17 widens, the skin material 12 continues from the slit part 17 and can be prevented from being broken beyond the length of the slit part 17.例文帳に追加

A push nut 40 is fitted to the protrusion 36 inserted through the through hole 26 of the back plate 20 . That is, the protrusion 36 is fixed by the push nut 40 . Therefore, for example, the outer diameter of the protrusion 36 is formed to be larger than the inner diameter of the through hole 26, and the protrusion 36 is press-fitted into the through hole 26 and fixed to the back plate 20. It is possible to more reliably prevent the 30 from coming off the skin material 12 (back plate 20).

Further, as shown in FIG. 7, the parting line PL formed on the peripheral edge portion (at least each corner portion 33) of the main body portion 32 when viewed from the direction perpendicular to the thickness direction of the main body portion 32 of the accessory 30 A linear peripheral edge portion 32A is formed on the front surface (designed surface 34) side, and an arcuate peripheral edge portion 32B is formed on the rear surface 32C side from the parting line PL.

Therefore, in at least each corner portion 33, for example, when the peripheral portion on the side of the back surface 32C from the parting line PL and the back surface 32C are formed in a shape in which the back surface 32C intersects at a substantially right angle (the corner portion 33 is formed in a substantially quarter cylinder shape), In comparison, the pressing force for pushing the upholstery material 12 present near each corner portion 33 into the concave portion 24 is reduced by the ornament 30 (each corner portion 33 of the main body portion 32).

As a result, even if the skin material 12 is formed relatively thick (for example, in a three-layer structure), when the main body part 32 of the ornament 30 is housed in the concave part 24 of the back plate 20 together with part of the skin material 12, , the occurrence of wrinkles in the upholstery material 12 in the vicinity of the periphery of the accessory 30 (specifically, each corner 33) can be effectively suppressed.

In addition, as shown in FIG. 8, the back surface 32C of each corner portion 33 of the main body portion 32 of the accessory 30, more specifically, the boundary portion between the arc-shaped peripheral edge portion 32B and the back surface 32C of each corner portion 33, each A ridgeline portion 35 having a curvature smaller than the curvature of the parting line PL at the corner portion 33 is formed (at the boundary portion between the arc-shaped peripheral portion 32B and the back surface 32C at each corner portion 33, each corner portion 33 A ridgeline portion 35 having a radius of curvature larger than the radius of curvature of the parting line PL is formed).

Therefore, compared to the case where a ridgeline portion (not shown) having a larger curvature than the curvature of the parting line PL is formed at the boundary portion between the arc-shaped peripheral edge portion 32B and the back surface 32C in each corner portion 33, The curvature of the arc-shaped peripheral edge portion 32B at each corner portion 33 becomes gentle (becomes a gentle spherical shape), and the skin material existing near each corner portion 33 due to the ornament 30 (each corner portion 33 of the main body portion 32) The pressing force for pushing 12 into recess 24 is further reduced.

As a result, even if the skin material 12 is formed relatively thick (for example, in a three-layer structure), when the main body part 32 of the ornament 30 is housed in the concave part 24 of the back plate 20 together with part of the skin material 12, , the occurrence of wrinkles in the upholstery material 12 in the vicinity of the peripheral edge portion (specifically, each corner portion 33) of the accessory 30 can be more effectively suppressed.

In addition, in the appearance of the design surface 34 of the ornament 30, at most, the parting line PL is visible. Therefore, even if the back surface 32C side from the parting line PL is the arc-shaped peripheral edge portion 32B, the design of the ornament 30 is not impaired by the arc-shaped peripheral edge portion 32B. Similarly, even if a ridgeline 35 is formed at the boundary between the arc-shaped peripheral edge 32B and the back surface 32C, the ridgeline 35 does not impair the design of the accessory 30.

Further, when the accessory 30 (body portion 32) is attached to the back plate 20 with the skin material 12 interposed therebetween, the plurality of small projections 37 provided on the back surface 32C of the accessory 30 (body portion 32) Since it bites into the surface of the skin material 12 , the skin material 12 can be sandwiched more effectively between the ornament 30 (body part 32 ) and the back plate 20 . Therefore, it is possible to suppress or prevent misalignment of the ornament 30 with respect to the upholstery 12 compared to a configuration in which the plurality of small projections 37 are not provided on the back surface 32C of the ornament 30 (main body portion 32). can.

The attachment structure 10 for the accessory 30 according to the present embodiment has been described above with reference to the drawings. The design can be changed as appropriate without departing from the gist of the invention. For example, the shape of the positioning protrusion 38 is not limited to the illustrated shape, and may be formed in a substantially cylindrical shape, for example. Also, the number and positions of the small protrusions 37 are not limited to those illustrated.

Although not shown, an enlarged diameter portion having a larger diameter than the inner diameter of the through hole 26 of the back plate 20 is formed at the tip of the protrusion 36, and the axial center portion of the protrusion 36 is hollowed out to form the protrusion. The expanded diameter portion 36 may be configured to be elastically deformable radially inward. With such a configuration, the protruding portion 36 is inserted into the through-hole 26 in a state in which the enlarged diameter portion is elastically deformed radially inward, and then restored, thereby being locked so as not to come off from the through-hole 26 . be. Therefore, in this case, the push nut 40 can be omitted.
