  Hereinafter, an embodiment in which the present invention is applied to an armrest of a rear seat of an automobile will be described with reference to the drawings.

  As shown in FIG. 1, the three-seat rear seat of an automobile has a seat 1 constituting a left seat 1L and a central seat 1C and a seat 2 constituting a right seat so as to be continuous from side to side. The sheet 1 and the sheet 2 are independent of each other.

  The seat 1 includes a seat back 3, a seat cushion 4, a headrest 5, and an armrest 6. An accommodation recess 8 in which the armrest 6 is disposed is formed in the front part of the portion constituting the central seat 1C of the seat back 3 so as to be recessed rearward. The armrest 6 is disposed in the housing recess 8 and is supported by the seat back 3 so as to be rotatable about a rotation axis extending in the left and right directions. The armrest 6 is disposed inside the housing recess 8 with the use position in which the distal end protrudes forward with respect to the base end supported by the seat back 3 and the distal end located above the base end. Rotate to and from the storage position. In the following description, the state where the armrest 6 is in the use position is used as a reference.

  As shown in FIG. 2, the armrest 6 includes a frame 11, a pad 12 supported by the frame 11, and a skin material 13 and an outer shell member 14 that cover the pad 12 in cooperation. The frame 11 includes a pair of left and right side frames 16 and a pan frame 17 spanned between the left and right side frames 16. Each side frame 16 is a sheet metal member, and has a transverse cross section formed in a groove shape, and is disposed so that the groove-shaped openings face each other. Each side frame 16 is supported at the base end portion (rear end portion in the use state) so as to be rotatable about the rotation axis extending in the left and right directions on the frame of the seat back 3. The pan frame 17 is formed of a steel plate, has a main surface that extends in the front-rear direction, and is coupled to upper portions of the left and right side frames 16 at left and right edges. A central portion in the left-right direction of the pan frame 17 projects upward to form a pedestal portion 17A. A support hole 17B penetrating vertically is formed in the center of the base portion 17A. The support hole 17B is formed in a long hole shape that is long in the front-rear direction.

  The outer shell member 14 is a member that covers at least a part of the surface of the pad 12, and includes a substrate portion 21 having two cup housing portions 21 </ b> A in the center portion and a loop portion 22 provided at an edge portion of the substrate portion 21. And a skin support portion 23 provided on the outer edge of the loop portion 22. The outer shell member 14 is made of a flexible resin material and is integrally formed by injection molding or the like. It is preferable that the outer shell member 14 has a hardness capable of penetrating a staple 26 described later. The outer shell member 14 may be a relatively soft resin such as an olefin elastomer or vinyl chloride, or a relatively hard resin such as polypropylene.

  21 A of cup accommodating parts are the recessed parts which protruded from the center of the board | substrate part 21 to the back surface side of the board | substrate part 21, and opened to the surface side of the board | substrate part 21. As shown in FIG. In the present embodiment, each cup housing portion 21A is formed in a bottomed cylindrical shape.

  The loop portion 22 extends along the edge of the substrate portion 21 and is formed in an annular shape so as to surround the two cup housing portions 21A. The loop portion 22 includes an inner wall 22A extending in the direction orthogonal to the substrate portion 21 from the edge of the substrate portion 21 and extending to the back side of the substrate portion 21, and an end portion on the side opposite to the substrate portion 21 side of the inner wall 22A. A bottom wall 22B extending in a direction perpendicular to the inner wall 22A from the side opposite to the substrate part 21 and a direction perpendicular to the substrate part 21 from the end of the bottom wall 22B opposite to the inner wall 22A side. And an outer wall 22 </ b> C extending to the surface side of the substrate portion 21. The loop portion 22 has a U-shaped (hairpin shape) cross section by an inner wall 22A, a bottom wall 22B, and an outer wall 22C. Inside the loop portion 22, an insertion groove 22 </ b> D (wood grain groove) that is defined by the inner wall 22 </ b> A, the bottom wall 22 </ b> B, and the outer wall 22 </ b> C and opens on the surface side of the substrate portion 21 is formed.

  The skin support portion 23 protrudes from the end portion on the side opposite to the bottom wall 22B side of the outer wall 22C to the side opposite to the substrate portion 21. The skin support portion 23 is a plate-like portion extending in parallel with the substrate portion 21 and extends in an annular shape along the outer wall 22C (loop portion 22). The surface 23 </ b> A of the skin support part 23 is formed in parallel with the surface 21 </ b> B of the substrate part 21. In addition, the end surface of the outer wall 22C opposite to the bottom wall 22B side and the surface 23A of the skin support portion 23 are formed by the thickness of the skin material 13 with respect to the surface 21B of the edge portion of the substrate portion 21. It is shifted and arranged on the back side.

  The skin material 13 is a member that covers at least a part of the surface of the pad 12, and may be a known skin material such as genuine leather, synthetic leather, fabric such as jersey or jacquard. The skin material 13 is formed in a bag shape from a single member or a plurality of members sewn together, and covers the frame 11 and the pad 12. The skin material 13 has an opening at a portion corresponding to the substrate portion 21 of the outer shell member 14. The opening of the skin material 13 is formed smaller than the size of the outer edge of the substrate portion 21. The edge portion 13A of the opening of the skin material 13 is inserted into the insertion groove 22D by a technique such as graining. A plurality of slits may be formed at appropriate positions on the edge 13 </ b> A of the skin material 13. By opening each slit when the skin material 13 is inserted into the insertion groove 22D, the skin material 13 is prevented from being pulled and the generation of wrinkles is suppressed.

  The width of the insertion groove 22D, which is the distance between the inner wall 22A and the outer wall 22C, is set slightly smaller than the thickness of the skin material 13 before the edge portion 13A of the skin material 13 is inserted. Accordingly, when the edge portion 13A of the skin material 13 is inserted into the insertion groove 22D, the insertion groove 22D is expanded by elastic deformation of the loop portion 22. The edge portion 13A of the skin material 13 is inserted into the insertion groove 22D and is sandwiched between the loop portions 22 (the inner wall 22A and the outer wall 22C) by the restoring force of the loop portion 22, and the slipping out of the insertion groove 22D is suppressed. Is done.

  In a state where the edge portion 13A of the skin material 13 is inserted into the insertion groove 22D, the inner wall 22A, the edge portion 13A of the skin material 13 and the outer wall 22C serve as holding members for suppressing the opening of the loop portion 22. Of staples 26 (stapler staples) are coupled. The staple 26 penetrates the inner wall 22A, the edge 13A of the skin material 13, and the outer wall 22C, and fastens them together. The staple 26 is attached to the inner wall 22A, the edge 13A of the skin material 13, and the outer wall 22C by a known stapler. The staple 26 reliably prevents the edge 13A of the skin material 13 from coming out of the insertion groove 22D. The staple 26 functions as a holding member that further strengthens the coupling structure between the loop portion 22 and the edge portion 13A of the skin material 13. The number and position of the staples 26 can be set as appropriate. For example, the staples 26 may be provided at a plurality of locations at equal intervals in the circumferential direction of the loop portion 22. Instead of the staple 26, a rivet that penetrates the inner side wall 22A, the edge 13A of the skin material 13, and the outer side wall 22C and fastens them together may be used.

  The back surface of the edge outer peripheral portion 13B, which is an annular outer peripheral portion surrounding the edge portion 13A of the skin material 13, is in contact with and supported by the surface 23A of the skin support portion 23. Thereby, the edge outer peripheral part 13B of the skin material 13 forms the planar surface 13C parallel to the skin support part 23, and an aesthetics improves. Further, the surface 13C of the edge outer peripheral portion 13B of the skin material 13 is arranged flush with the surface 21B of the substrate portion 21, and the integrity of the substrate portion 21 and the skin material 13 is improved, and the aesthetic appearance is improved.

  The skin material 13 and the outer shell member 14 that are coupled to each other and form a bag shape are arranged so as to cover the frame 11 and the pad 12, and constitute the outer surface of the armrest 6. The skin material 13 and the outer shell member 14 are arranged with respect to the frame 11 so that the cup housing portion 21A is fitted in the support hole 17B and the back surface of the substrate portion 21 is in contact with the upper surface of the pedestal portion 17A.

  The pad 12 is made of a flexible material such as urethane foam. The pad 12 is formed with a recess 12A corresponding to the cup housing portion 21A, and the cup housing portion 21A is fitted to the recess 12A.

  A method for manufacturing the armrest 6 configured as described above will be described. First, the outer shell member 14 and the skin material 13 are assembled together. When the skin material 13 is composed of a plurality of members, the outer shell member 14 may be assembled to the skin material 13 before the skin materials 13 are stitched together, and the skin materials 13 are stitched together to form a bag. After that, the outer shell member 14 may be assembled to the skin material 13.

  The outer shell member 14 and the skin member 13 are assembled by first inserting the edge 13A of the skin member 13 into the insertion groove 22D of the outer shell member 14 and subsequently receiving the edge 13A of the skin member 13 by the stapler. The staple 26 is driven into the portion 22, and the inner wall 22 </ b> A, the edge 13 </ b> A of the skin material 13, and the outer wall 22 </ b> C are joined together by the staple 26. The graining of the edge portion 13A of the skin material 13 into the insertion groove 22D may be performed using the assembling apparatus 30 shown in FIG. The assembling apparatus 30 includes a base 31, a skin support block 33 supported by the base 31 via a biasing member 32 that is a compression coil spring, a wood grain piece 34 projecting from the base 31, An outer shell member support base 35 slidably provided with respect to the base 31.

  The outer shell member support base 35 has a support recess 35 </ b> A into which the rear surface side of the outer shell member 14 is fitted. The outer shell member 14 is positioned relative to the outer shell member support 35 by fitting the back surface side of the outer shell member 14 into the support recess 35A. A space 35 </ b> B that allows the loop portion 22 to expand and the skin support portion 23 to move is formed in a portion corresponding to the loop portion 22 and the skin support portion 23 of the support recess 35 </ b> A. The outer shell member 14 is supported by the outer shell member support 35 and the surface side faces the base 31 side.

  The skin support block 33 is supported by the base 31 so as to be slidable in the same direction as the sliding direction of the outer shell member support 35. The biasing member 32 biases the skin support block 33 toward the outer shell member support base 35 (in a direction away from the base 31). On the skin support block 33, the edge outer peripheral portion 13B of the skin material 13 is placed. A plurality of skin support blocks 33 may be provided corresponding to the outer peripheral edge portion 13B of the skin material 13, or one ring-shaped member corresponding to the outer peripheral edge portion 13B of the skin material 13 may be provided. When the skin material 13 is formed in a bag shape, the skin material 13 may be disposed so as to receive the outer shell member 14 and the outer shell member support base 35 therein, or the base material 31 and the skin support block are turned upside down. 33 and wood grain 34 may be arranged to be received inside.

  The wood grain piece 34 is arranged at a position corresponding to the insertion hole of the outer shell member 14 supported by the outer shell member support base 35. Above the grained piece 34, an edge 13A of the skin material 13 supported by the skin support block 33 is disposed.

  In the assembling apparatus 30, when the outer shell member support base 35 moves to the base 31 side, the skin support block 33 first comes into contact with the outer shell member support base 35 via the edge outer peripheral portion 13 </ b> B of the skin material 13, The outer peripheral edge portion 13B of the skin material 13 is sandwiched between the skin support block 33 and the outer shell member support base 35. Thereafter, the outer skin support block 33 moves to the base 31 side together with the outer shell member support 35 while the biasing member 32 is compressed. Furthermore, when the outer shell member support base 35 moves to the base 31 side, the grained piece 34 enters the insertion groove 22D while winding the edge portion 13A of the skin material 13. At this time, the loop portion 22 expands by elastic deformation in the space. Further, since the skin material 13 is sandwiched between the skin support block 33 and the outer shell member support base 35 at the edge outer peripheral portion 13B, only the edge portion 13A is grained into the insertion hole. Thereafter, when the outer shell member support base 35 moves away from the base 31, the grained piece 34 comes out of the insertion groove 22 </ b> D, the loop portion 22 is restored, and the edge portion 13 </ b> A of the skin material 13 is between the loop portions 22. It is pinched.

  After the edge portion 13A is inserted into the insertion groove 22D, the outer shell member 14 and the skin material 13 are removed from the assembling apparatus 30, and the staple 26 is driven into the loop portion 22 using a stapler. Thereby, the loop portion 22 and the edge portion 13A of the skin material 13 are integrally coupled by the staple 26. In this way, the outer shell member 14 and the skin material 13 are coupled to each other.

  The outer shell member 14 and the skin material 13 that are coupled to each other are formed in a bag shape, and after the frame 11 is disposed therein, the outer shell member 14 and the skin material 13 are disposed in the mold. Thereafter, the outer shell member 14 and the skin material 13 are filled with a foam material such as urethane to form the pad 12. The armrest 6 is formed as described above.

  In the armrest 6 configured as described above, since the coupling structure between the skin material 13 and the outer shell member 14 does not require a sewing operation, the work load is small. Further, since the loop portion 22 and the edge portion 13A of the skin material 13 are coupled by the staple 26, the slippage of the skin material 13 from the insertion groove 22D is reliably suppressed. Further, in the structure in which the edge portion 13A of the skin material 13 is inserted into the insertion groove 22D, the appearance of the boundary portion between the outer shell member 14 and the skin material 13 is stabilized, and the aesthetic appearance is improved. Further, since the loop portion 22 and the insertion groove 22D are annularly formed along the edge portion of the outer shell member 14, the edge portion 13A of the skin material 13 is inserted into the insertion groove 22D over the entire circumference, and the outer shell member. 14 and the appearance of the joint portion of the skin material 13 are improved.

  Next, the armrest 50 according to the second embodiment will be described with reference to FIG. The armrest 6 according to the second embodiment is different from the armrest 6 according to the first embodiment only in that a clip 51 is provided instead of the staple 26 as a holding member. In the following description of the armrest 6 according to the second embodiment, the same components as those of the armrest 6 according to the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the armrest 6 according to the second embodiment, the clip 51 holds the loop portion 22 in which the edge portion 13A of the skin material 13 is inserted into the insertion groove 22D from the outside. The clip 51 is made of metal or resin and has a U-shaped cross section. The clip 51 receives the loop portion 22 inside, and sandwiches the inner wall 22A and the outer wall 22C together with the edge 13A of the skin material 13 from the thickness direction. The clip 51 further prevents the edge portion 13A of the skin material 13 from coming out of the insertion groove 22D. The number of the clips 51 is arbitrary, and the clips 51 may be attached to the loop portion 22 at appropriate positions in the circumferential direction. The clip 51 may be a long member extending along the loop portion 22.

  Although the description of the specific embodiment is finished as described above, the present invention is not limited to the above embodiment and can be widely modified. For example, although the above embodiment is an example applied to the armrest 6, the surface structure including the skin material 13 and the outer shell member 14 may be applied to the seat back 3 and the seat cushion 4.

  Various shapes can be applied to the outer shell member 14. For example, the cup accommodating portion 21A may be omitted from the substrate portion 21, and a planar outer surface may be formed. In this case, the outer shell member 14 can constitute a table by the substrate portion 21. Moreover, the outer shell member 14 can be used as a protective member by disposing the outer shell member 14 in a portion where the skin material 13 is likely to be worn. In addition, by changing the shape of the cup housing portion 21 </ b> A to a shape suitable for various desired products, a housing unit suitable for the product can be formed.
