[0007] Hereinafter, an armrest 10 of the present disclosure will be described with reference to Figs. 1 to 10. As shown in Fig. 1, the armrest 10 has a rectangular parallelepiped shape that is long in the front-rear direction, and is attached, for example, to the center of the rear seat of the vehicle. The armrest 10 is rotatable around the rear side, and when not in use, is stored in the backrest of the rear seat and used as part of the seat. Note that the armrest 10 may be configured to be attached to a location other than the rear seat, or may be configured to be non-rotatable.

[0008] As shown in Fig. 2, armrest 10 has a support frame 20 that serves as the framework of armrest 10 inside a bag-shaped skin material 15 formed into a bag shape by sewing multiple skin materials together, and the support frame 20 is covered with a pad 12 (corresponding to a "foamed product" in the claims) made of foamed resin. Armrest 10 also has a cup holder 30 (corresponding to a "cup container" in the claims) and a bezel 40 that fits around the outside of cup holder 30, embedded in pad 12. Bag-shaped skin material 15 is stretchable.

[0009] As shown in Fig. 3, the support frame 20 includes a pair of side frames 21, a rear end connecting member 22 that connects the rear ends of the pair of side frames 21, a front end connecting member 24 that connects the front ends of the pair of side frames 21, and an intermediate connecting member 25 that connects the intermediate portions of the pair of side frames 21. The front end connecting member 24 is formed into a substantially C-shape from a round bar, and is disposed so that the slit of the C faces rearward. A rotating shaft 23 that serves as the rotating shaft of the armrest 10 is fixed to the rear end of each side frame 21.

[0010] As shown in Fig. 2 and Fig. 3, the bezel 40 includes a bezel body 41 formed in a rectangular frame shape, a frame-shaped protruding wall 43 extending along the inner edge of the bezel body 41 inside the bezel body 41, and a bezel connecting portion 42 connecting the bezel body 41 and the frame-shaped protruding wall 43. The bezel body 41 has a frame-shaped upper wall portion 41A, an inner wall 41B hanging down from the inner edge of the upper wall portion 41A, and an outer wall 41C hanging down from the outer edge of the upper wall portion 41A, and has a double-wall structure. The outer wall 41C and the inner wall 41B are connected by a plurality of engagement ribs 41L. The lower end of the outer wall 41C is located lower than the lower end of the inner wall 41B, and a step 41M that positions the outer side downward is provided at the lower end of the engagement rib 41L.

[0011] 2, bezel connecting portion 42 protrudes inward from the vertical center of inner side wall 41B of bezel main body 41, and frame-shaped protruding wall 43 protrudes upward from the inner edge of bezel connecting portion 42. The upper end of frame-shaped protruding wall 43 is located slightly below the upper end of bezel main body 41. A frame groove 40M is formed between frame-shaped protruding wall 43, inner side wall 41B of bezel main body 41, and bezel connecting portion 42, and the inner portion of frame-shaped protruding wall 43 forms insertion opening 40A through which cup holder 30 is inserted.

[0012] The bezel 40 has a hanging wall 44 that hangs down from the inner edge of the bezel connecting portion 42. A part of the hanging wall 44 serves as an extension wall portion 44A that extends to a position near the lower end of the cup holder 30. A through hole 45 is formed in the extension wall portion 44A.

[0013] The bezel 40 is fixed by fitting an engagement portion (not shown) from the outside into the front end connecting member 24 of the support frame 20. In addition, as shown in Fig. 2, a step 41M of the bezel main body 41 sandwiches the front end connecting member 24 in the left-right direction, thereby restricting misalignment of the bezel 40 in the left-right direction.

[0014] 1, cup holder 30 has a structure in which flange portion 33 protrudes outward from the upper opening edge of cup receiving portion 31 formed in a container shape. Cup receiving portion 31 is formed in a dumbbell shape in a plan view, with two single cup receiving portions 35 lined up on the left and right and connected by a communication path 36.

[0015] In detail, the single cup receiving portion 35 has a container side wall 35B rising from the outer edge of a bottom wall 35A that is rectangular in plan view. The container side wall 35B of the single cup receiving portion 35 is inclined so that the opening becomes larger toward the top. The communication path 36 penetrates and connects adjacent container side walls 35B of the two single cup receiving portions 35, and has a communication wall 36B that connects the container side walls 35B of the two single cup receiving portions 35, and a communication bottom wall 36A that extends flush with the bottom wall 35A of the single cup receiving portion 35.

[0016] 2, a flange groove 34 that opens downward is formed in the flange portion 33. Specifically, the flange portion 33 includes a protruding wall 33A that extends outward from the upper end of the cup receiving portion 31, and an outer facing wall 33B that hangs down from the outer edge of the protruding wall 33A and faces the cup receiving portion 31. The flange groove 34 is formed between the outer facing wall 33B and the cup receiving portion 31.

[0017] Cup holder 30 is fixed to bezel 40 with cup receiving portion 31 inserted from above into insertion opening 40A of bezel 40. In the state in which cup holder 30 is fixed to bezel 40, frame-shaped protruding wall 43 of bezel 40 is received in flange groove 34 of cup holder 30, and outer facing wall 33B of cup holder 30 is received in frame groove 40M of bezel 40.

[0018] 1 and 2, the edge of the bag opening 15A of the bag-shaped skin material 15 is sandwiched between the flange portion 33 of the cup holder 30 and the bezel 40. Specifically, the edge of the bag opening 15A is sandwiched between the groove bottom wall of the flange groove 34 (i.e., the protruding wall 33A) and the frame-shaped protruding wall 43, and is also sandwiched between the groove bottom wall of the frame groove 40M (i.e., the bezel connecting portion 42) and the outer facing wall 33B. As a result, the bag-shaped skin material 15 is stretched so as to abut against the inner side wall 41B and the upper wall portion 41A of the bezel main body 41 of the bezel 40, and the bag opening 15A is formed into a rectangular shape.

[0019] The armrest 10 of this embodiment is provided with an abutment protrusion 37 that protrudes inward from the container side wall 35B in the single cup receiving portion 35 of the cup holder 30. In detail, as shown in Figs. 1 and 2, a circular side wall opening 37A is formed through the center of the container side wall 35B of the single cup receiving portion 35. Also, the bag-shaped skin material 15 is formed with an extension 15E (corresponding to the "membrane body" in the claims) that is folded back inwardly and downwardly from a portion sandwiched between the groove bottom wall of the flange groove 34 and the frame-shaped protruding wall 43 and overlaps the container side wall 35B from the outside. This extension 15E bulges toward the inside of the cup holder 30 (the inside of the single cup receiving portion 35) through the side wall opening 37A and is recessed toward the pad 12, and the portion of the extension 15E that protrudes from the side wall opening 37A toward the inside of the cup holder 30 serves as the above-mentioned abutment protrusion 37. The side wall opening 37A and the contact protrusion 37 are not provided on the container side wall 35B that is connected by the communication path 36.

[0020] Recess 37U on the pad 12 side of contact protrusion 37 is filled with cup-holding elastic portion 12A, which is part of pad 12. As shown in Fig. 4, when a cylindrical body 100 such as a cup or a bottle is inserted into cup holder 30 (single cup receiving portion 35), cup-holding elastic portion 12A elastically deforms via contact protrusion 37, and the elastic force of this elastic portion 12A stably holds cylindrical body 100 accommodated in cup holder 30 (single cup receiving portion 35).

[0021] The extension portion 15E of the bag-shaped skin material 15 is held so as to overlap the container side wall 35B by being sandwiched between the extension wall portion 44A of the bezel 40 and the container side wall 35B. The extension wall portion 44A of the bezel 40 extends downward from a portion of the hanging wall 44 that faces the container side wall 35B where the abutment protrusion 37 is provided. The through hole 45 of the extension wall portion 44A is disposed at a position substantially facing the side wall opening 37A, and the cup-holding elastic portion 12A enters the recessed portion 37U of the abutment protrusion 37 through the through hole 45.

[0022] In addition, a locking hole 16 is formed at the end of the extension portion 15E of the bag-shaped skin material 15, and a locking claw 44B formed at the lower end of the extension wall portion 44A is inserted into the locking hole 16 (see Figure 2).

[0023] The armrest 10 of this embodiment is manufactured as follows.

[0024] First, prepare the cup holder 30. The cup holder 30 has a side wall opening 37A formed in the container side wall 35B (see FIG. 6).

[0025] 5, the support frame 20 incorporated in the pouch-shaped skin material 15 is set in the first die 70A of the foam molding die 70, and then the bezel 40 is inserted into the pouch-shaped skin material 15 and fixed to the support frame 20. At this time, the locking claws 44B of the bezel 40 are hooked into the locking holes 16 of the pouch-shaped skin material 15 to fix the pouch-shaped skin material 15 to the bezel 40. In this embodiment, the foam molding die 70 is configured so that the front portion of the armrest 10 is located on the lower side.

[0026] 6, the cup receiving portion 31 of the cup holder 30 is pushed into the bag opening 15A and fixed. Then, the frame-shaped protruding wall 43 of the bezel 40 enters the flange groove 34 of the cup holder 30, and the bag-shaped skin material 15 is sandwiched between the groove bottom wall of the flange groove 34 and the frame-shaped protruding wall 43, and the outer facing wall 33B of the cup holder 30 enters the frame groove 40M of the bezel 40, and the bag-shaped skin material 15 is sandwiched between the groove bottom wall of the frame groove 40M and the outer facing wall 33B. In this state, the extension portion 15E of the bag-shaped skin material 15 overlaps the container side wall 35B of the cup holder 30 from the outside, closing the side wall opening 37A. The side wall opening 37A of the cup holder 30 and the through hole 45 of the bezel 40 are arranged next to each other with the extension portion 15E of the bag-shaped skin material 15 sandwiched therebetween.

[0027] Next, as shown in Fig. 7, the second die 70B of the foam molding die 70 is closed. A recess 70C is formed in the second die 70B at a position adjacent to the side wall opening 37A. Then, as shown in Fig. 8, raw material for foaming resin 12Z that will become the pad 12 (see Fig. 2) is injected into the bag-shaped skin material 15 and foamed.

[0028] Here, as shown in Fig. 9, when the foamed resin 12Z foams up to the vicinity of the through-hole 45 of the bezel 40, the extension 15E of the bag-shaped skin material 15 is pushed by the foamed resin 12Z that has passed through the through-hole 45 of the bezel 40 and expands in the recess 70C of the second mold 70B through the side wall opening 37A of the cup holder 30 (i.e., expands inwardly of the cup holder 30). As shown in Fig. 10, the foamed resin 12Z in the recess 70C expands up to a point where the extension 15E abuts against the inner surface of the recess 70C of the second mold 70B. As a result, the extension 15E forms the abutment protrusion 37 that protrudes from the side wall opening 37A of the cup holder 30 to the inside of the cup holder 30, and the foamed resin 12Z (pad 12) forms the cup-holding elastic portion 12A that fills the recess 37U of the abutment protrusion 37.

[0029] When the foaming of the foamed resin 12Z is ​​completed, the pad 12 is formed in the bag-shaped skin material 15, and the armrest 10 is completed in which the pad 12, the bag-shaped skin material 15, the support frame 20, the cup holder 30, and the bezel 40 are integrated (see FIG. 2). The second mold 70B of the foam molding die 70 of this embodiment is a split mold in which the periphery of each recess 70C is split. In detail, as shown in FIG. 10, in the second mold 70B, the split parts 70G around each recess 70C are connected to the main body part 70H, which is the majority, via pins 70P extending at an angle with respect to the mold opening direction. When the second mold 70B is opened, the split parts 70G move sideways away from the contact protrusions 37 in conjunction with the movement of the second mold 70B. This allows the armrest 10 to be removed from the foam molding die 70 without applying a large load to the contact protrusions 37. The foam molding die is not limited to the configuration of this embodiment as long as the armrest 10 can be removed from the foam molding die without applying a large load to the contact protrusion 37. For example, the foam molding die may have a configuration in which the pin 70P does not exist and the divided portion 70G is not connected to the main body portion 70H.

[0030] The configuration of armrest 10 of this embodiment has been described above. Next, the action and effect of armrest 10 will be described. Armrest 10 of this embodiment is provided with abutment protrusion 37 that protrudes inward from container side wall 35B in single cup receiving portion 35 of cup holder 30, and cup-holding elastic portion 12A, which is a part of pad 12, is filled on the pad 12 side of abutment protrusion 37. With this, when a cylindrical body 100 such as a cup or bottle is inserted into cup holder 30 (single cup receiving portion 35), cup-holding elastic portion 12A is elastically deformed via abutment protrusion 37 pressed by cylindrical body 100, and the elastic force of this elasticity stably holds cylindrical body 100 accommodated in cup holder 30 (single cup receiving portion 35).

[0031] In addition, because cup-holding elastic part 12A, which applies a resilient force to hold cylindrical body 100, is formed from a part of pad 12, the number of parts can be reduced compared to a configuration in which other elastic members are incorporated. Moreover, because cup-holding elastic part 12A is formed at the same time as foaming resin 12Z for forming pad 12 is foamed, an increase in the amount of work required during manufacturing is prevented.

[0032] Furthermore, since the contact protrusion 37 is formed by the extension 15E extending from the bag opening 15A of the bag-shaped skin material 15, an increase in the number of parts is prevented. Also, since the extension 15E is sandwiched between the extension wall 44A of the bezel 40 and the container side wall 35B, the extension 15E is prevented from being displaced due to the pressure of the foamed resin 12Z during foaming.

[0033] [Other embodiments] (1) In the above embodiment, the contact protrusion 37 is formed by the extension 15E which is an extension of a part of the bag-shaped skin material 15, but it may be formed by another film body. In this case, for example, the other film body may be arranged only near the side wall opening 37A in the container side wall 35B, or the other film body may be joined integrally to the bag-shaped skin material 15. It is also possible to change the appearance of the armrest 10 by giving the other film body a different color or texture from the bag-shaped skin material 15. Also, the other film body may be arranged inside the container side wall 35B.

[0034] (2) In the above embodiment, the abutment protrusion 37 was formed by expanding the planar extension portion 15E by foaming the foam resin 12Z, but it may also be formed by a pre-formed expanded shape (which may be the extension portion 15E).

[0035] (3) As shown in FIG. 11, the contact protrusion 37 may be formed by thinning a portion of the container side wall 35B of the cup holder 30 and bulging it inward to make it elastically deformable.

[0036] (4) The contact protrusion 37 may be formed of an elastomer blocking member. In this case, the elastomer blocking member may be overlapped on the outside of the container side wall 35B, or may be configured to protrude from the opening edge of the side wall opening 37A of the container side wall 35B.

[0037] (5) The contact protrusion does not have to be a membrane, and may be, for example, a lever 38 hinged to the side wall of the container as shown in Fig. 12, or may have a structure including a membrane and a lever 38 stacked on the inside of it as shown in Fig. 13. Also, the contact protrusion may have a structure including a membrane having an outer recess and a reinforcing member fitted into the recess, and the reinforcing member presses against the foamed resin.

[0038] (6) The number of single cup receiving portions 35 may be one, or three or more.

[0039] (7) The single cup receiving portions 35 do not have to be connected to each other by the communication paths 36 .

[0040] (8) The single cup receiving portion 35 may be circular in plan view.

[0041] (9) The bag-shaped covering material 15 and the cup holder 30 may be assembled to the pad 12 that has been foamed in advance.

[0042] (10) In the above embodiment, the extension portion 15E was fixed by clamping it between the extension wall portion 44A of the bezel 40 and the container side wall 35B, but this is not limited to this. For example, a locking claw for fixing the lower end portion of the extension portion 15E may be provided on the lower end portion of the container side wall 35B of the cup holder 30, or the extension portion 15E may be adhered to the container side wall 35B.

[0043] In addition, although this specification and drawings disclose specific examples of the technology included in the scope of the claims, the technology described in the claims is not limited to these specific examples, but includes various modifications and variations of the specific examples, as well as parts of the specific examples taken alone.
