  The skin-integrated foam molded product shown in FIGS. 1 and 2 is a pull-out armrest 10 for a vehicle seat, and FIG. 1 shows a state where the armrest 10 is pulled out from a seat back.

  The armrest 10 includes a skin 11, a resin foam 12 filled inside the skin 11, and a cup holder 13 as a component mounted on the skin 11.

  The skin 11 of the armrest 10 is formed by sewing a plurality of skin pieces in a bag shape, turning over with a return opening 14 so that a seam allowance is on the inside, and forming the return opening 14 by binding. A mounting hole 18 for mounting the cup holder 13 is formed on the upper surface of the skin 11 on which the occupant's arm is placed with the armrest 10 pulled out.

  The cup holder 13 has a flange portion 13 a arranged outside the outer skin 11 so as to overlap the opening edge of the mounting hole 18, and a buried portion 13 b 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 formed integrally.

  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 formed 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 forms an upper surface on which the occupant's arm can be placed in a state where the armrest 10 shown in FIG. 1 is pulled out, a skin piece 11b that forms a lower surface, and 11c that forms left and right side surfaces. 11d, and these four pieces of skin are sewn into 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 a cushioning property. 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 wading 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 wading material 16. It is cut out from the raw material and formed.

  The mounting hole 18 is formed in a skin piece 11a constituting the upper surface, and the skin piece 11a has a sealing 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 are 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, and the seal portion 17 can be, for example, a resin foam such as a flexible polyurethane foam. In this example, the wadding material 16 is made of a resin foam such as a flexible polyurethane foam, and the seal portion 17 is formed using a wadding material. In particular, the wadding material 16 constituting the skin piece 11a is In this example, the sealing portion 17 is formed separately from the wadding material 16 constituting the skin piece 11a. By forming the seal portion 17 using a wadding material, the material can be effectively used.

  The sealing portion 17 which is separate from the wadding material 16 constituting the skin piece 11a is formed in an annular shape corresponding to the shape of the mounting hole 18. The outer edge of the seal portion 17 is superimposed on the opening edge of the mounting hole 18 on the back side of the skin piece 11a, and is joined to the opening edge of the mounting hole 18 by sewing or bonding.

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

  The manufacturing process of the armrest 10 will be described with reference to FIGS.

  First, as shown in FIG. 5, the sewing margin of the outer skin 11 sewn in a bag shape is turned over at the return opening 14 so that the sewing margin is on the inside, and the return opening 14 is stitched. A seal portion 17 is joined to the skin piece 11a, and an inner edge portion of the seal portion 17 is disposed so as to extend inside the mounting hole 18 from an 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 inside of the skin 11 through the mounting hole 18. At this time, the inner edge of the seal portion 17 that extends from the opening edge of the mounting hole 18 to the inside of the mounting 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 of the seal portion 17 drawn into the skin 11 is easily deformed according to the shape of the outer peripheral surface of the embedded portion 13b. Therefore, the insertion resistance of the embedded portion 13b into the mounting hole 18 is reduced, and the crushing and deformation of the skin 11 due to the insertion of the embedded portion 13b into the mounting hole 18 are suppressed. Thereby, the work of mounting the cup holder 13 into the mounting hole 18 becomes easy.

  Next, an injection nozzle of a foamed resin material is mounted on a nozzle insertion port (not shown) provided on the skin 11, and the skin 11 is integrally foamed with the cup holder 13 and the injection nozzle mounted. Is loaded into the cavity. Then, the foamed resin material is injected into the inside of the skin 11 through the injection nozzle. The foamed resin material foams inside the skin 11, and the resin foam 12 is formed.

  Here, the foamed resin material injected into the inside of the skin 11 infiltrates the wadding material 16 and the seal portion 17 of each of the skin pieces 11a to 11d exposed inside the skin 11, and infiltrates the wadding material 16 and the seal portion 17. The foamed resin material thus formed also foams. At this time, the seal portion 17 expands in response to the foaming of the foamed resin material infiltrated into the seal portion 17, and the inner edge 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. Adhere tightly 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, the skin 11, the resin foam 12, and the cup holder 13 are removed from the integrated foam molding die, and the injection nozzle is removed from the nozzle insertion port. The armrest 10 is obtained through the above steps.

  By providing the flexible sealing portion 17 that can be impregnated with the foamed resin material in the mounting hole 18 of the skin 11 in which the cup holder 13 is mounted, the mounting operation of the cup holder 13 into the mounting hole 18 is facilitated. In addition, 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 concave portion 20 is provided on the outer peripheral surface of the buried portion 13 b of the cup holder 13 where the inner edge portion of the seal portion 17 is in close contact, and at least a part of the inner edge portion of the seal portion 17 is formed by the concave portion 20. Is housed in As a result, an uneven labyrinth seal is formed between the buried portion 13b and the seal portion 17, the sealing property is enhanced, and the 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, of the skin pieces 11 a to 11 d forming the skin 11, the skin piece 11 a constituting the upper surface on which the occupant's arm can be placed with the armrest 10 pulled out, and the state where the armrest 10 is stored. A skin piece 11b constituting a lower surface in contact with the occupant's back 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 wading material 16 are in a non-face-bonded state, and the surface material 19 and the wading material 16 are separated except for the edge sewn to another skin piece. I have. The “non-surface bonding state” refers to 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 to the edge of the other skin pieces 11b to 11d. The surface material 19 and the wadding material 16 are locally bonded by a seam or a state in which the surface material 19 and the wadding material 16 are linearly joined, or a decorative stitch provided at the center of the skin piece 11a excluding the edge. This includes the state where they are joined in a point-like or linear manner.

  The wadding material 16 that is in a non-planar joining state with the surface material 19 can be formed in a shape different from the surface material 19. Therefore, in the present embodiment, the sealing 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 forming the skin piece 11a, and a through hole smaller than the mounting hole 18 is formed in the wadding material 16 also forming the skin piece 11a. The wadding member 16 has an extension portion extending from the opening edge of the mounting hole 18 to the inside of the mounting hole 18, and the extension portion serves as a seal portion 17.

  In this manner, by forming the seal portion 17 integrally with the wadding material 16 constituting the skin piece 11a, the operation of joining the seal portion 17 formed separately from the wadding material 16 to the skin piece 11a is omitted. As a result, the manufacturing efficiency of the armrest 10 can be improved.

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

  The skin-integrated foam molded product shown in FIG. 9 is a vehicle seat cushion 30 to which a child seat 50 can be attached and detached. A pair of fixing hooks 51 are provided on the child seat 50, 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, for example, a vehicle floor, and reaches the seat surface from a side opposite to the seat surface of the seat cushion 30 through a cut formed in the seat cushion 30.

  The seat cushion 30 includes a skin 31, a resin foam 32 filled inside the skin 31, and a pair of guide cups 33 as components mounted on the skin 31. The guide cups 33 respectively 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 in a bag shape. The skin piece 31a 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 wading 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 33 a arranged outside the skin 31 so as to overlap the opening edge of the mounting hole 38, and a buried portion 33 b housed inside the skin 31 through the mounting hole 38. The skin piece 31a is provided with a seal portion 37 which is in close contact with the outer peripheral surface of the buried portion 33b 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 forming the resin foam 32, and is formed in an annular shape corresponding to the shape of the mounting hole 38. The outer edge of the seal portion 37 is overlapped with the opening edge of the mounting hole 38 on the back side of the skin piece 31a, and is joined to the opening edge of the mounting hole 38. When the wadding material 36 forming the skin piece 31a is flexible and can be impregnated with a foamed resin material, the seal portion 37 may be formed using a wadding material.

  The inner edge of the seal portion 37 is disposed to extend inside the mounting hole 38 beyond the opening edge of the mounting hole 38. The inner edge portion of the seal portion 37 is drawn into the inside of the skin 31 along the outer peripheral surface of the embedded portion 33b of the guide cup 33 housed inside the skin 31 through the mounting hole 38, and the embedded portion is retracted. 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 seam allowance of the outer skin 31 sewn in a bag shape is turned inside out, and then the embedded portion of the guide cup 33 is buried. 33 b is inserted into the inside of the skin 31 through the mounting hole 38. At this time, the inner edge portion of the seal portion 37 extending to the inside of the mounting hole 38 from the opening edge of the mounting hole 38 is drawn into the inside of 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 according to 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 collapse and deformation of the skin 31 due to the insertion of the embedded portion 33b into the mounting hole 38 are suppressed. This facilitates the work of mounting the guide cup 33 into the mounting hole 38.

  Subsequently, a foamed resin material is injected into the skin 31. The foamed resin material foams 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 the 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. Adhere tightly 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 into 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 concave portion is provided on the outer peripheral surface of the embedded portion 33 b of the guide cup 33 where the inner edge of the seal portion 37 is in close contact, and at least the inner edge of the seal portion 37 is provided. A part may be accommodated in the recess. Thereby, leakage of the foamed resin material from the mounting hole 38 can be further suppressed.

  Further, similarly to the modification of the armrest 10 shown in FIG. 8, when the surface material 35 forming the skin piece 31a is made of natural leather, and the surface material 35 and the wading material 36 are in a non-plane joint state, The mounting hole 38 is formed in the surface material 35, and the through hole smaller than the mounting hole 38 is formed in the wadding material 36, so that the mounting hole 38 extends from the opening edge of the mounting hole 38 to the inside of the mounting hole 38. An extended portion may be provided on the wadding material 36, and the extended portion may serve as a seal portion 37, and the seal portion 37 may be formed integrally with the wadding material 36. Thereby, the operation of joining the sealing portion 37 formed separately from the wadding material 36 to the skin piece 31a can be omitted, and the production efficiency of the seat cushion 30 can be increased.

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

  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 41a constituting a side surface of the seat back 40 into a bag shape. The skin piece 41a 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 wading material 46 are joined over the entire surface.

  A mounting hole 48 into which the lever housing 43 is mounted is formed in the skin piece 41a. The lever housing 43 has a flange portion 43a arranged outside the outer skin 41 so as to overlap the opening edge of the mounting hole 48, and a buried portion 43b housed inside the outer skin 41 through the mounting hole 48. The skin piece 41a is provided with a seal portion 47 that is in close contact with the outer peripheral surface of the embedded portion 43b of the lever housing 43 mounted on 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 forming the resin foam 42, and is formed in an annular shape corresponding to the shape of the mounting hole 48. The outer edge of the seal portion 47 is overlapped with the opening edge of the mounting hole 48 on the back side of the skin piece 41a, and is joined to the opening edge of the mounting hole 48. When the wading material 46 forming the skin piece 41a is flexible and can be impregnated with a foamed resin material, the seal portion 47 may be formed using a wadding material.

  The inner edge 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. The inner edge of the seal portion 47 is drawn into the inside of the skin 41 along the outer peripheral surface of the embedded portion 43b of the lever housing 43 housed inside the skin 41 through the mounting hole 48, and the embedded portion is retracted. 43b is in close contact with the entire outer circumference.

  The manufacturing process of the seat back 40 is the same as the manufacturing process of the armrest 10 described above. First, the sewing margin of the sewn skin 41 is turned inside out, and then the embedded portion of the lever housing 43 is installed. 43 b is inserted into the skin 41 through the mounting hole 48. At this time, the inner edge of the seal portion 47 that extends from the opening edge of the mounting hole 48 to the inside of the mounting 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 of the seal portion 47 drawn into the skin 41 is easily deformed according to 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 collapse and deformation of the skin 41 due to the insertion of the embedded portion 43b into the mounting hole 48 are suppressed. This facilitates the mounting operation of the lever housing 43 into the mounting hole 48.

  Subsequently, a foamed resin material is injected into the inside of the skin 41. The foamed resin material foams inside the skin 41, and the resin foam 42 is formed. The foamed resin material injected into the inside of the skin 41 infiltrates the seal portion 47, and the foamed resin material infiltrated into the seal portion 47 also foams. At this time, the seal portion 47 expands in response to the foaming of the foamed resin material infiltrated into the seal portion 47, and the inner edge portion of the seal portion 47 is pressed against the outer peripheral surface of the embedded portion 43b, and the entire outer peripheral surface of the embedded portion 43b is pressed.
