  1 and 2 show an example of a skin-integrated foam-molded product for describing an embodiment of the present invention.

  1 and 2 is a pull-out type armrest 10 for a vehicle seat, and FIG. 1 shows a state in which the armrest 10 is pulled out from a seat back.

  The armrest 10 includes an outer skin 11, a resin foam 12 filled inside the outer skin 11, and a cup holder 13 as a component attached to the outer skin 11.

  The skin 11 of the armrest 10 is formed by sewing a plurality of skin pieces into a bag shape, turning it upside down with the return opening 14 so that the seam allowance is on the inside, and stitching the return opening 14 together. A mounting hole 18 in which the cup holder 13 is mounted is formed on the upper surface of the skin 11 on which the arm of the occupant is placed with the armrest 10 being pulled out.

  The cup holder 13 has a flange portion 13 a that is arranged outside the outer skin 11 so as to overlap the opening edge portion of the mounting hole 18, and an embedded portion 13 b that is housed inside the outer skin 11 through the mounting hole 18. The cup holder 13 is made of, for example, a synthetic resin material, and the flange portion 13a and the embedded portion 13b are integrally formed.

  The resin foam 12 is formed by foaming a foamed resin material inside the skin 11 in a state where the cup holder 13 is mounted in the mounting hole 18, and is molded integrally with the skin 11 and the cup holder 13. The foamed resin material is not particularly limited, and examples thereof include foamed polyurethane.

  3 and 4 show a cross section of the armrest 10.

  The skin 11 of the armrest 10 includes a skin piece 11a that constitutes an upper surface on which an occupant's arm is placed in a state in which the armrest 10 shown in FIG. 11d and these four skin pieces are sewn together in a bag shape.

  Each of the skin pieces 11a to 11d is formed by two layers of a surface material 15 made of synthetic leather or fabric and a wadding material 16 laminated on the back side of the surface material 15. The wading material 16 is a sheet material having cushioning properties. As the wading material 16, for example, a resin foam such as a flexible polyurethane foam can be used.

  The surface material 15 made of synthetic leather or fabric and the wadding material 16 are joined over the entire surface by, for example, laminating, and the skin pieces 11a to 11d are formed by joining the surface material 15 and the wadding material 16. It is cut out from the original fabric.

  The mounting hole 18 is formed in the skin piece 11a constituting the upper surface, and the skin piece 11a has a seal portion that is in close contact with the outer peripheral surface of the embedded portion 13b of the cup holder 13 mounted in the mounting hole 18 over the entire circumference. 17 is provided.

  The seal portion 17 is made of a sheet material that is flexible and can be impregnated with a foamed resin material that forms the resin foam 12. As the seal portion 17, for example, a resin foam such as a flexible polyurethane foam can be used. In this example, the wading material 16 is made of a resin foam such as a flexible polyurethane foam, and the seal portion 17 is formed using the wadding material. In particular, the wading material 16 constituting the skin piece 11a is the surface material 15. In this example, which is bonded over the entire surface, the seal portion 17 is formed separately from the wading material 16 constituting the skin piece 11a. By forming the seal portion 17 using the wadding material, the material can be effectively used.

  The seal portion 17, which is a separate body from the wadding material 16 constituting the skin piece 11 a, is formed in an annular shape corresponding to the shape of the mounting hole 18. And the outer edge part of the seal | sticker part 17 is piled up on the opening edge part of the mounting hole 18 in the back side of the skin piece 11a, and is joined to the opening edge part of the mounting hole 18 by sewing or adhesion | attachment.

  The inner edge portion of the seal portion 17 is disposed so as to extend inside the mounting hole 18 from the opening edge of the mounting hole 18. And the inner edge part of the seal | sticker part 17 is drawn in the inside of the skin 11 along the outer peripheral surface of the embedded part 13b of the cup holder 13 accommodated in the inside of the skin 11 through the mounting hole 18, and is embedded in the retracted state. It is in close contact with the outer peripheral surface of 13b over the entire circumference.

  With reference to FIG.5 and FIG.6, the manufacturing process of the armrest 10 is demonstrated.

  First, as shown in FIG. 5, the bag 11 is turned upside down at the return port 14 so that the seam allowance of the skin 11 is inward, and the return port 14 is stitched. A seal portion 17 is joined to the skin piece 11 a, and the inner edge portion of the seal portion 17 is disposed so as to extend inside the mounting hole 18 from the opening edge of the mounting hole 18.

  Next, as shown in FIG. 6, the embedded portion 13 b of the cup holder 13 is inserted into the outer skin 11 through the mounting hole 18. At this time, the inner edge portion of the seal portion 17 arranged to extend to the inside of the attachment hole 18 from the opening edge of the attachment hole 18 is drawn into the skin 11 along the outer peripheral surface of the embedded portion 13b. Since the seal portion 17 is flexible, the inner edge portion of the seal portion 17 drawn into the skin 11 is easily deformed following the shape of the outer peripheral surface of the embedded portion 13b. Accordingly, the insertion resistance of the embedded portion 13b into the mounting hole 18 is reduced, and the crushing and deformation of the epidermis 11 accompanying the insertion of the embedded portion 13b into the mounting hole 18 is suppressed. This facilitates the mounting operation of the cup holder 13 in the mounting hole 18.

  Next, an injection nozzle made of a foamed resin material is attached to a nozzle insertion opening (not shown) provided in the skin 11, and the skin 11 is molded into an integral foaming mold in a state where the cup holder 13 and the injection nozzle are attached. Loaded into the cavity. Then, the foamed resin material is injected into the skin 11 through the injection nozzle. The foamed resin material foams inside the skin 11 and the resin foam 12 is molded.

  Here, the foamed resin material injected into the inside of the skin 11 infiltrates the wading material 16 and the seal portion 17 of each of the skin pieces 11 a to 11 d exposed inside the skin 11, and infiltrates the wading material 16 and the seal portion 17. The foamed resin material also foams. At this time, the seal portion 17 expands in response to foaming of the foamed resin material infiltrated into the seal portion 17, and the inner edge portion of the seal portion 17 is pressed against the outer peripheral surface of the embedded portion 13b, and the entire outer peripheral surface of the embedded portion 13b is pressed. It adheres firmly over the circumference. Thereby, leakage of the foamed resin material from the mounting hole 18 is suppressed.

  After the molding of the resin foam 12 is completed, the skin 11, the resin foam 12, and the cup holder 13 are taken out from the integral foam molding die, and the injection nozzle is removed from the nozzle insertion port. The armrest 10 is obtained through the above steps.

  Thus, by providing the mounting hole 18 of the skin 11 in which the cup holder 13 is mounted with the flexible seal portion 17 that can be impregnated with the foamed resin material, the mounting operation of the cup holder 13 in the mounting hole 18 is facilitated. And leakage of the foamed resin material from the mounting hole 18 can be suppressed.

  FIG. 7 shows a modification of the armrest 10.

  In the example shown in FIG. 7, an annular recess 20 is provided on the outer peripheral surface of the embedded portion 13 b of the cup holder 13 where the inner edge of the seal portion 17 is in close contact, and at least a part of the inner edge of the seal portion 17 is the recess 20. Is housed in. Thereby, an uneven labyrinth seal is formed between the embedded portion 13 b and the seal portion 17, the sealing performance is improved, and leakage of the foamed resin material from the mounting hole 18 can be further suppressed.

  FIG. 8 shows another modification of the armrest 10.

  In the example shown in FIG. 8, among the skin pieces 11 a to 11 d that form the skin 11, the skin piece 11 a that constitutes the upper surface on which the arm of the occupant is placed and the armrest 10 are housed. The skin piece 11b constituting the lower surface in contact with the back of the occupant is formed by two layers of a surface material 19 made of natural leather and a wadding material 16 laminated on the back side of the surface material 19.

  In order to maintain the texture of natural leather, the surface material 19 and the wadding material 16 are in a non-surface-bonded state, and the surface material 19 and the wadding material 16 are separated from each other except for the edge that is sewn together with other skin pieces. Yes. The “non-surface bonded state” means a state in which two adjacent layers are not bonded over the entire surface, for example, the edge of the skin piece 11a is sewn with the edges of the other skin pieces 11b to 11d. The surface material 19 and the wadding material 16 are locally bonded by a state in which the surface material 19 and the wadding material 16 are linearly joined by a seam, or a decorative stitch provided at the center of the skin piece 11a excluding the edge. In particular, the state of being joined in the form of dots or lines shall be included.

  The wadding material 16 in a non-surface-bonded state with the surface material 19 can be formed in a shape different from that of the surface material 19. Therefore, in this example, the seal portion 17 is formed integrally with the wadding material 16 constituting the skin piece 11a. That is, a mounting hole 18 is formed in the surface material 19 constituting the skin piece 11a, and a through-hole smaller than the mounting hole 18 is formed in the wading material 16 also constituting the skin piece 11a. An extending portion that extends from the opening edge to the inside of the mounting hole 18 is provided in the wading material 16, and this extending portion is used as a seal portion 17.

  Thus, by forming the seal portion 17 integrally with the wadding material 16 constituting the skin piece 11a, the work of joining the seal portion 17 formed separately from the wadding material 16 to the skin piece 11a is omitted. The manufacturing efficiency of the armrest 10 can be increased.

  FIG. 9 shows another example of a skin-integrated foam-molded product for explaining an embodiment of the present invention.

  The skin-integrated foam-molded product shown in FIG. 9 is a vehicle seat cushion 30 to which the child seat 50 can be attached and detached. The child seat 50 is provided with a pair of fixing hooks 51, and a pair of anchors 34 with which the hooks 51 are respectively engaged are arranged at the rear end of the seating surface of the seat cushion 30. The anchor 34 is fixed to the vehicle floor, for example, and reaches the seating surface from the side opposite to the seating surface of the seat cushion 30 through a notch formed in the seat cushion 30.

  The seat cushion 30 includes an outer skin 31, a resin foam 32 filled inside the outer skin 31, and a pair of guide cups 33 as components attached to the outer skin 31. The guide cups 33 surround the anchors 34 arranged at the rear end of the seating surface of the seat cushion 30.

  FIG. 10 shows a cross section of the seat cushion 30.

  The skin 31 of the seat cushion 30 is formed by sewing a plurality of skin pieces including a skin piece 31a constituting a seating surface of the seat cushion 30 into a bag shape. The skin piece 31 a is formed by two layers of a surface material 35 and a wadding material 36 laminated on the back side of the surface material 35. In this example, the surface material 35 is made of synthetic leather or fabric, and the surface material 35 and the wadding material 36 are joined over the entire surface.

  A mounting hole 38 in which the guide cup 33 is mounted is formed in the skin piece 31a. The guide cup 33 has a flange portion 33a that is disposed outside the outer skin 31 so as to overlap the opening edge of the mounting hole 38, and an embedded portion 33b that is accommodated in the outer skin 31 through the mounting hole 38. The skin piece 31 a is provided with a seal portion 37 that is in close contact with the outer peripheral surface of the embedded portion 33 b of the guide cup 33 mounted in the mounting hole 38 over the entire circumference.

  The seal portion 37 is made of a sheet material that is flexible and can be impregnated with a foamed resin material that forms the resin foam 32, and is formed in an annular shape corresponding to the shape of the mounting hole 38. The outer edge portion of the seal portion 37 is superimposed on the opening edge portion of the mounting hole 38 on the back side of the skin piece 31 a and is joined to the opening edge portion of the mounting hole 38. In addition, when the wading material 36 constituting the skin piece 31a is flexible and can be impregnated with the foamed resin material, the seal portion 37 may be formed using a wadding material.

  The inner edge portion of the seal portion 37 is disposed so as to extend inside the mounting hole 38 from the opening edge of the mounting hole 38. And the inner edge part of the seal | sticker part 37 is drawn in the inside of the skin 31 along the outer peripheral surface of the embedding part 33b of the guide cup 33 accommodated in the inside of the skin 31 through the mounting hole 38, and is embedded in the retracted state. It is in close contact with the outer peripheral surface of 33b over the entire circumference.

  The manufacturing process of the seat cushion 30 is the same as the manufacturing process of the armrest 10 described above. First, the seat 31 is turned upside down so that the seam allowance of the skin 31 sewed in a bag shape is inside, and then the embedded portion of the guide cup 33 33 b is inserted into the skin 31 through the mounting hole 38. At this time, the inner edge portion of the seal portion 37 disposed so as to extend to the inside of the attachment hole 38 from the opening edge of the attachment hole 38 is drawn into the skin 31 along the outer peripheral surface of the embedded portion 33b. Since the seal portion 37 is flexible, the inner edge portion of the seal portion 37 drawn into the skin 31 is easily deformed following the shape of the outer peripheral surface of the embedded portion 33b. Therefore, the insertion resistance of the embedded portion 33b into the mounting hole 38 is reduced, and the crushing and deformation of the epidermis 31 accompanying the insertion of the embedded portion 33b into the mounting hole 38 is suppressed. Thereby, the mounting work of the guide cup 33 to the mounting hole 38 is facilitated.

  Subsequently, a foamed resin material is injected into the skin 31. The foamed resin material is foamed inside the skin 31 and the resin foam 32 is formed. The foamed resin material injected into the inside of the skin 31 infiltrates the seal portion 37, and the foamed resin material infiltrated into the seal portion 37 also foams. At this time, the seal portion 37 expands in response to foaming of the foamed resin material infiltrated into the seal portion 37, and the inner edge portion of the seal portion 37 is pressed against the outer peripheral surface of the embedded portion 33b, and the entire outer peripheral surface of the embedded portion 33b is pressed. It adheres firmly over the circumference. Thereby, leakage of the foamed resin material from the mounting hole 38 is suppressed.

  The seat cushion 30 is obtained through the above steps. Thereafter, a cut through which the anchor 34 is inserted is formed across the skin 31, the resin foam 32 and the guide cup 33.

  As in the modification of the armrest 10 shown in FIG. 7, an annular recess is provided on the outer peripheral surface of the embedded portion 33 b of the guide cup 33 where the inner edge portion of the seal portion 37 is in close contact, and at least the inner edge portion of the seal portion 37 is provided. A part may be accommodated in the recess. Thereby, the leakage of the foamed resin material from the mounting hole 38 can be further suppressed.

  Similarly to the modification of the armrest 10 shown in FIG. 8, when the surface material 35 constituting the skin piece 31a is made of natural leather, and the surface material 35 and the wadding material 36 are in a non-surface bonded state, A mounting hole 38 is formed in the surface material 35, and a through hole smaller than the mounting hole 38 is formed in the wading material 36, thereby extending the inner side of the mounting hole 38 from the opening edge of the mounting hole 38. The protruding portion may be provided in the wading material 36, the extending portion may be a seal portion 37, and the seal portion 37 may be formed integrally with the wadding material 36. Thereby, the operation | work which joins the seal | sticker part 37 formed separately from the wading material 36 to the skin piece 31a can be abbreviate | omitted, and the manufacturing efficiency of the seat cushion 30 can be improved.

  FIG. 11 shows another example of a skin-integrated foam-molded product for explaining an embodiment of the present invention.

  The skin-integrated foam-molded product shown in FIG. 11 is a vehicle seat back 40 having a walk-in mechanism.

  The seat back 40 includes an outer skin 41, a resin foam 42 filled inside the outer skin 41, and a lever housing 43 as a component attached to the outer skin 41. The lever housing 43 accommodates the flange portion of the lever 44 by exposing the operation portion of the lever 44 disposed at the upper end portion of the side surface of the seat back 40.

  FIG. 12 shows a cross section of the seat back 40.

  The skin 41 of the seat back 40 is formed by sewing a plurality of skin pieces including a skin piece 41 a constituting the side surface of the seat back 40 into a bag shape. The skin piece 41 a is formed by two layers of a surface material 45 and a wadding material 46 laminated on the back side of the surface material 45. In this example, the surface material 45 is made of synthetic leather or fabric, and the surface material 45 and the wadding material 46 are joined over the entire surface.

  A mounting hole 48 in which the lever housing 43 is mounted is formed in the skin piece 41a. The lever housing 43 has a flange portion 43a that is arranged outside the outer skin 41 so as to overlap the opening edge portion of the mounting hole 48, and an embedded portion 43b that is housed inside the outer skin 41 through the mounting hole 48. The skin piece 41 a is provided with a seal portion 47 that is in close contact with the outer peripheral surface of the embedded portion 43 b of the lever housing 43 mounted in the mounting hole 48 over the entire circumference.

  The seal portion 47 is made of a sheet material that is flexible and can be impregnated with a foamed resin material that forms the resin foam 42, and is formed in an annular shape corresponding to the shape of the mounting hole 48. The outer edge portion of the seal portion 47 is overlapped with the opening edge portion of the mounting hole 48 on the back side of the skin piece 41 a and joined to the opening edge portion of the mounting hole 48. When the wading material 46 constituting the skin piece 41a is flexible and can be impregnated with the foamed resin material, the seal portion 47 may be formed using a wadding material.

  The inner edge portion of the seal portion 47 is disposed so as to extend inside the mounting hole 48 from the opening edge of the mounting hole 48. And the inner edge part of the seal | sticker part 47 is drawn in the inside of the outer skin 41 along the outer peripheral surface of the embedding part 43b of the lever housing 43 accommodated in the inside of the outer skin 41 through the mounting hole 48, and is embedded in the retracted state. It is in close contact with the outer peripheral surface of 43b over the entire circumference.

  The manufacturing process of the seat back 40 is the same as the manufacturing process of the armrest 10 described above. First, the bag 41 is turned upside down so that the seam allowance of the skin 41 is inside, and then the embedded portion of the lever housing 43 43 b is inserted into the outer skin 41 through the mounting hole 48. At this time, the inner edge portion of the seal portion 47 arranged so as to extend from the opening edge of the attachment hole 48 to the inside of the attachment hole 48 is drawn into the skin 41 along the outer peripheral surface of the embedded portion 43b. Since the seal portion 47 is flexible, the inner edge portion of the seal portion 47 drawn into the skin 41 is easily deformed following the shape of the outer peripheral surface of the embedded portion 43b. Therefore, the insertion resistance of the embedded portion 43b into the mounting hole 48 is reduced, and the crushing and deformation of the epidermis 41 accompanying the insertion of the embedded portion 43b into the mounting hole 48 is suppressed. Thereby, the mounting operation of the lever housing 43 in the mounting hole 48 is facilitated.

  Subsequently, a foamed resin material is injected into the skin 41. The foamed resin material is foamed inside the skin 41, and the resin foam 42 is molded. The foamed resin material injected into the skin 41 infiltrates the seal portion 47, and the foamed resin material infiltrated into the seal portion 47 also foams.
