[0003] [Patent Document 1] JP 2016-88458 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-mentioned prior art, the number of beverage containers that can be held in the cup holder is limited to the number of holes formed in the cup holder housing, and while it is possible to increase the number of holes, increasing the number of holes in the cup holder would result in a corresponding increase in the size of the cup holder.

[0005] In consideration of the above, an object of the present invention is to provide a cup holder, an armrest, and a vehicle seat that can increase the number of containers that can be held while maintaining the size of the cup holder. [Means for solving the problem]

[0006] The cup holder of the first aspect comprises a storage section having a hole formed therein capable of accommodating a container, a tray overlying the storage section and having a through hole formed therein capable of communicating with the hole, and an unfolding mechanism that enables the tray to be unfolded relative to the storage section and, when unfolded, protrudes beyond the outer contour of the storage section in a plan view, allowing a container to be held relative to the through hole.

[0007] The cup holder according to the first aspect includes a container, a tray, and an unfolding mechanism. The container has a hole formed therein capable of accommodating a container, and the tray is placed on top of the container. The tray has a through hole formed therein capable of communicating with the hole, and the container can be accommodated in the hole through the through hole.

[0008] In addition, the tray can be deployed into the storage section by the deployment mechanism, and when the tray is deployed, the tray protrudes (expands) beyond the outer shape of the storage section in a plan view, and the through-holes can hold containers. In other words, in this embodiment, the number of containers that can be held can be increased while the size of the cup holder is maintained.

[0009] The cup holder of the second aspect is the cup holder of the first aspect, wherein the hole portions are provided in a direction intersecting the unfolding direction of the tray, and a communication portion is formed that connects the multiple hole portions and includes the multiple hole portions, making it possible to store small items.

[0010] In the cup holder according to the second aspect, the holes are provided in a direction intersecting the unfolding direction of the tray, so that the storage section can hold a plurality of containers. The holes are connected by communication sections, and the communication sections allow the storage of small items including the holes. This allows the storage of rectangular plate-shaped members such as smartphones, for example.

[0011] A cup holder according to a third aspect is a cup holder according to the first or second aspect, wherein the through hole and the hole portion are circular, and the inner diameter dimension of the through hole is set to be smaller than the inner diameter dimension of the hole portion.

[0012] In the cup holder of the third aspect, the through hole and the hole portion are circular, the inner diameter dimension of the through hole is set to be smaller than the inner diameter dimension of the hole portion, and the inner diameter dimensions of the through hole and the hole portion are different.

[0013] For example, containers with large external dimensions (or external diameters, the same applies below) such as plastic bottles are held by the storage unit, and containers with small external dimensions such as canned coffee are held by the tray. In other words, it is possible to select the storage unit or tray according to the size of the container.

[0014] A cup holder according to a fourth aspect is a cup holder according to any one of the first to third aspects, wherein the hole has a circular shape and is formed in a stepped shape so that the inner diameter dimension on the back side of the hole is smaller than the inner diameter dimension on the opening side of the hole.

[0015] In the cup holder of the fourth aspect, the hole is circular and is formed in a stepped manner so that the inner diameter dimension at the back of the hole is smaller than the inner diameter dimension at the opening side of the hole, thereby making it possible for the hole to hold containers of different outer dimensions.

[0016] For example, a container with a small external dimension, such as a can of coffee, is held in contact with the bottom wall of the hole, and a container with a large external dimension, such as a plastic bottle, is held in contact with the side wall of a stepped section provided above the bottom wall of the hole. In other words, one hole can hold containers with different external dimensions.

[0017] A cup holder according to a fifth aspect is the cup holder according to any one of the first to fourth aspects, wherein the deployment mechanism is a hinge member that rotatably supports the tray relative to the storage portion.

[0018] In the cup holder of the fifth aspect, the deployment mechanism is a hinge member, and the tray is rotatably supported relative to the storage portion via the hinge member, making it possible to deploy the tray with a simple configuration.

[0019] A cup holder according to a sixth aspect is a cup holder according to any one of the first to fourth aspects, wherein the unfolding mechanism is a sliding member that supports the tray so that it can slide horizontally relative to the storage section.

[0020] In the cup holder of the sixth aspect, the deployment mechanism is a sliding member that supports the tray so that it can slide horizontally relative to the storage section via the sliding member, making it possible to deploy the tray with a simple configuration.

[0021] The armrest of the seventh aspect is configured to be storable or deployable, has a cup holder of any one of the first to sixth aspects provided at its tip, and has a plurality of holes provided along a width direction intersecting the storage or deployment direction.

[0022] In the armrest according to the seventh aspect, the armrest is provided so as to be storable or deployable, and a cup holder is provided at the tip of the armrest. Therefore, by deploying the armrest, the cup holder at the tip can be used. Also, the cup holder has a plurality of holes provided along the width direction of the armrest, which intersects with the storable or deployable direction. Here, it is possible to enjoy the effects obtained by the cup holder according to any one of the first to sixth aspects.

[0023] The vehicle seat of the eighth aspect is provided in the rear seat and comprises a seat cushion on which an occupant sits, a seat back supporting the back of the occupant seated on the seat cushion, and an armrest of the seventh aspect supported rotatably around an axis portion extending along the seat width direction at the center of the seat width direction of the seat back.

[0024] The vehicle seat according to the eighth aspect includes a seat cushion, a seat back, and an armrest, the seat cushion is provided in the rear seat, an occupant sits on the seat cushion, and the seat back supports the back of the occupant seated on the seat cushion. The armrest is supported at the center of the seat back in the seat width direction so as to be rotatable about an axis extending in the seat width direction. Here, it is possible to enjoy the effects obtained by the armrest according to the seventh aspect. Effect of the Invention

[0027] Hereinafter, a vehicle seat according to the present embodiment will be described with reference to the drawings. Note that the arrow FR shown as appropriate in the following drawings indicates the forward direction (the direction in which the seated person faces) in the seat front-rear direction of the vehicle seat, the arrow UP indicates the upward direction in the seat vertical direction, and the arrow IN indicates the inward direction in the seat width direction. Hereinafter, when the directions of front-rear, up-down, and inside-outside are simply used for the description, they refer to front-rear in the seat front-rear direction, up-down in the seat vertical direction, and inside-outside in the seat width direction when facing the traveling direction of the vehicle, unless otherwise specified.

[0028] (Vehicle seat configuration) As shown in FIG. 1, a vehicle seat 10 according to this embodiment is a rear seat for seating three people.

[0029] The seat includes a seat cushion 12 on which a vehicle occupant sits, a seat back 14 that supports the occupant's back, and three head rests 16 that support the occupant's head.

[0030] The seat back 14 is, for example, a 6:4 split folding type, and is divided into a right seat back 14R for two-seater use and a left seat back 14L for one-seater use. Two headrests 16 are attached to the upper end of the right seat back 14R, and one headrest 16 is attached to the upper end of the left seat back 14L.

[0031] An armrest 18 according to this embodiment is attached to the left side of the right seatback 14R. The armrest 18 is rotatable about an axis P (axis) that is provided along the seat width direction relative to the right seatback 14R between a deployed position shown in Fig. 1 and a storage position where the armrest 18 is stored in a recess 20 formed in the left side of the right seatback 14R.

[0032] When the armrest 18 is in the deployed position, the front-rear, left-right, up-down and up-down directions of the armrest 18 coincide with the front-rear, left-right, up-down and up-down directions of the vehicle seat 10. When the armrest 18 is in the stored position, the front-rear direction of the armrest 18 coincides with the height direction of the seat back 14, the left-right direction of the armrest 18 coincides with the left-right direction of the vehicle seat 10, and the up-down direction of the armrest 18 coincides with the front-rear direction of the seat back 14.

[0033] First Embodiment (Cup holder configuration)

[0034] Here, the configuration of the cup holder according to the first embodiment will be described.

[0035] 1, a storage recess 24 is formed in the tip of armrest 18, and cup holder 22 is stored in storage recess 24. Cup holder 22 is manufactured, for example, by injection molding of resin, and has a rectangular box shape with an open upper side. Cup holder 22 is disposed in tip 18A of armrest 18 with the left-right direction (width direction of armrest 18) as the longitudinal direction, and is stored in storage recess 24 with the open upper side.

[0036] 2A and 2B, for example, two (plural) holes 28 are formed in the storage section 26 of the cup holder 22, and beverage containers 23, 25 (see FIG. 3B) can be held side-by-side in the left-right direction. A communication section 30 having a substantially rectangular shape in a plan view penetrates the two holes 28, and the two holes 28 are connected by the communication section 30. Small items can be stored including the two holes 28 and the communication section 30. The number of holes 28 does not necessarily have to be two, and one or more may be sufficient.

[0037] Also, a plate-shaped tray 32 is provided in the storage section 26 so as to overlap thereon. For this reason, for example, when the armrest 18 is unfolded, the upper surface 26A of the storage section 26 is set to be lower than the upper surface 18B of the armrest 18 by the plate thickness of the tray 32. When the tray 32 overlaps the upper surface 26A of the storage section 26, the upper surface 32A of the tray 32 and the upper surface 18B of the armrest 18 are set to be approximately flush with each other. However, this is not limited to this, and it goes without saying that when the tray 32 overlaps the upper surface 26A of the storage section 26, the upper surface 32A of the tray 32 may protrude from the upper surface 18B of the armrest 18.

[0038] In addition, the tray 32 is formed with two through holes 34 that can communicate with the two hole parts 28 formed in the storage section 26 when the tray 32 is overlapped with the storage section 26. The hole parts 28 and the through hole 34 are each formed in a circular shape, and the inner diameter dimension of the through hole 34 is set to be smaller than the inner diameter dimension of the hole part 28. Therefore, when the tray 32 is overlapped with the upper surface 26A of the storage section 26, the communication part 30 is blocked by the tray 32. Note that the hole parts 28 and the through hole 34 do not necessarily have to be circular, and may be angular. In addition, the inner diameter dimension of the through hole 34 does not necessarily have to be set to be smaller than the inner diameter dimension of the hole part 28.

[0039] 3A and 3B, a step 36 may be provided in the accommodation portion 26. The step 36 is formed to have a larger diameter than the bottom wall 28B of the hole 28 on the upper side of the bottom wall 28B. Note that a plurality of step portions 36 may be provided along the height direction of the hole 28 so that the diameter becomes larger toward the inlet side of the hole 28.

[0040] On the other hand, in this embodiment, as shown in Figures 2A and 2B, the tray 32 is rotatably supported on the upper surface 26A of the storage section 26 via a hidden hinge (hinge member, deployment mechanism) 38. The hidden hinge 38 is provided along the width direction of the armrest 18, one side of the hidden hinge 38 is provided on the left and right of the tip of the upper surface 26A of the storage section 26, and the other side of the hidden hinge 38 is provided on the left and right of the rear end of the storage section 26 in the deployed state. As shown in Figure 2B, when the tray 32 is deployed via the hidden hinge 38, the upper surface of the tray 32 and the upper surface 26A of the storage section 26 are set to be at approximately the same height.

[0041] In this embodiment, since a hidden hinge 38 is used as the hinge member, the hidden hinge 38 is not visible when the tray 32 overlaps with the upper surface 26A of the storage section 26 as shown in Fig. 2A. Note that, as long as the tray 32 can be rotatably supported with respect to the upper surface 26A of the storage section 26, the hinge member is not limited to the hidden hinge 38. Therefore, a normal hinge may be used as the hinge member.

[0042] (Cup holder function and effects) Next, the operation and effects of the cup holder according to the first embodiment will be described.

[0043] 2A and 2B, cup holder 22 includes storage section 26, tray 32, and hidden hinge 38. Storage section 26 is formed with hole 28 capable of storing containers 23, 25 (see FIG. 3B), and tray 32 is placed on storage section 26. Tray 32 is formed with through-hole 34 capable of communicating with hole 28, and containers 23, 25 can be stored in hole 28 through through-hole 34.

[0044] Further, the tray 32 can be unfolded into the storage section 26 by means of a hidden hinge 38, and when the tray 32 is unfolded, the tray 32 protrudes (expands) from the outer shape of the storage section 26 in a plan view, and containers can be held in the through holes 34. In other words, in this embodiment, the number of containers that can be held can be increased while the size of the cup holder 22 is maintained.

[0045] In this embodiment, two holes 28 are provided along a direction intersecting the unfolding direction of the tray 32, so that two containers can be held in the storage section 26. The two holes 28 are connected by a communication section 30, and the communication section 30 allows the storage of small items including the two holes 28. This allows the storage of rectangular plate-like members such as smartphones, for example.

[0046] Furthermore, in this embodiment, the through hole 34 and the hole portion 28 are circular, the inner diameter of the through hole 34 is set to be smaller than the inner diameter of the hole portion 28, and the inner diameters of the through hole 34 and the hole portion 28 are different. For example, containers with large outside dimensions (outer diameters) such as plastic bottles are held by the storage portion 26, and containers with small outside dimensions such as canned coffee are held by the tray 32. In other words, the storage portion 26 or the tray 32 can be selected according to the size of the container.

[0047] In addition, in this embodiment, as shown in Figures 3A and 3B, hole portion 28 has a circular shape and may be formed in a stepped shape so that the inner diameter dimension on the back side of hole portion 28 is smaller than the inner diameter dimension on the opening 28A side of hole portion 28. In this case, for example, container 25 having a small outer dimension such as a canned coffee is held in contact with bottom wall 28B of hole 28, and container 23 having a large outer dimension such as a plastic bottle is held in contact with side wall 36A of step-like staircase 36 provided above bottom wall 28B of hole 28. That is, in this embodiment, one hole 28 can hold containers having different outer dimensions.

[0048] In this embodiment, as shown in Figures 2A and 2B, the unfolding mechanism is a hidden hinge 38, and the tray 32 is rotatably supported relative to the storage section 26 via the hidden hinge 38, making it possible to unfold the tray 32 with a simple configuration.

[0049] In addition to the hinge, an integral hinge (hinge member) 40 may be used as the deployment mechanism as shown in Fig. 4B as Modification 1. By using an integral hinge as the deployment mechanism in this way, the part is completed with resin only, eliminating the need for a hinge as a part and making it possible to reduce the number of parts.

[0050] Also, for example, by providing a positioning recess 42 on the storage section 26 side and a positioning pin 44 on the tray 32 side, as shown in Fig. 4A, when the tray 32 overlaps the storage section 26, the positioning pin 44 may be accommodated in the positioning recess 42, and the tray 32 may be positioned with respect to the storage section 26. Although not shown, the positioning pin 44 may be provided on the storage section 26 side, and the positioning recess 42 may be provided on the tray 32 side.

[0051] Furthermore, in the case of the integral hinge 40, unlike the hidden hinge 38, it becomes necessary to maintain the expanded position of the tray 32. For this reason, as shown in Fig. 4B, abutment portions 46, 48 may be provided at the rear end of the tray 32 and at the site corresponding to the front end of the storage section 26 when the tray 32 is expanded. When the tray 32 is expanded, the abutment portion 46 provided on the tray 32 side may abut against the abutment portion 48 provided on the storage section 26 side, thereby maintaining the expanded position of the tray 32.

[0052] 5A and 5B, a hinge member 54 using links 50, 52 may be used as the deployment mechanism. For example, the hinge member 54 is composed of links 50, 52 and pins 56, 58, 60, with the pin 56 being provided on the tray 32 side and the pin 60 being provided on the armrest 18 side.

[0053] The tray 32 and the link 50 are rotatable about a pin 56, and the link 52 is rotatable about a pin 60. When the tray 32 is unfolded, the angle formed by the link 50 and the link 52 may be set to be approximately 90 degrees, so that the tray 32 is maintained in the unfolded state. In this way, in the second modification, the strength retention performance of the tray 32 is improved by providing the hinge member 54.

[0054] Second embodiment Next, the configuration of the cup holder according to the second embodiment will be described.

[0055] 6A and 6B, in this embodiment, the deployment mechanism constituting part of cup holder 62 is a slide member 64, which supports tray 32 so that it can slide horizontally relative to storage section 26. For example, as shown in Figures 7A and 7B, tray 32 is disposed at tip portion 66A of armrest 66 above storage section 26 such that upper surface 32A of tray 32 and the upper surface of armrest 66 are substantially flush with each other.

[0056] An outer rail (slide member) 68 is provided on the armrest 66 along the longitudinal direction of the armrest 66 above the storage section 26. Meanwhile, an inner rail (slide member) 70 is provided on the tray 32 side, which is engaged with the outer rail 68 and can slide along the outer rail 68. A stopper (not shown) is provided on the outer rail 68, and the tray 32 is set to slide to a stop at a predetermined stroke.

[0057] In this manner, by using the slide member 64 as the unfolding mechanism, the tray 32 is supported so as to be slidable along the horizontal direction relative to the storage section 26 via the slide member 64, so that in this embodiment, as in the first embodiment, it is possible to unfold the tray 32 with a simple configuration.

[0058] In the above embodiment, as shown in FIG. 1, for example, a cup holder 22 applied to an armrest 18 provided on a vehicle seat 10 has been described. However, the cup holder of the present invention does not necessarily have to be provided on a vehicle seat and can also be used as a cup holder alone.

[0059] Although the present invention has been described above by way of the embodiment, the present invention can be modified and embodied without departing from the spirit and scope of the present invention. Furthermore, the scope of the present invention is not limited to the above embodiment. [Explanation of symbols]
