Description

[Technical Field]

[0001] The present invention relates to a vehicle seat, and more particularly to an armrest with a cup holder. [Background technology]

[0002] Patent Document 1 below discloses an armrest provided on a vehicle seat. This armrest has a main body and an article holding part. The article holding part is a cup holder and has a bottom plate part provided in a through hole and a string that supports the bottom plate part. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-23741 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned prior art, if the cup to be held in the cup holder is large, the center of gravity of the cup is high and unstable, resulting in unstable holding of the cup while the vehicle is moving.

[0005] An object of the present invention is to provide an armrest and a vehicle seat equipped with a cup holder that can stably hold cups of various sizes. [Means for solving the problem]

[0006] The armrest of the first aspect comprises an armrest main body portion attached to the seat back of a vehicle seat, a cylindrical cup holder main body portion provided on the armrest main body portion and opening on both sides in the vertical direction of the armrest, and a cup holder bottom portion removably attached to the lower end of the cup holder main body portion.

[0007] In the armrest of the first aspect, a cup holder main body is provided on an armrest main body attached to the seat back of a vehicle seat. The cup holder main body is cylindrical with openings on both sides in the vertical direction of the armrest. A cup holder bottom is attached to the lower end of the cup holder main body. In this armrest, if the cup size is normal or small, the cup holder bottom can be attached to the lower end of the cup holder main body and used as usual. In addition, if the cup size is large, the cup holder bottom can be removed from the lower end of the cup holder main body and the cup can be fitted into the cup holder main body. This allows cups of various sizes to be stably held.

[0008] The armrest of the second aspect is the same as that of the first aspect, except that the lower end of the cup holder main body is provided with a main body flange that extends inward of the cup holder main body, and the upper end of the cup holder bottom is provided with a bottom flange that hooks onto the main body flange from above the armrest.

[0009] In the armrest of the second aspect, a bottom flange provided at the upper end of the cup holder bottom hooks onto a main body flange provided at the lower end of the cup holder main body. This allows the cup holder bottom to be held in the cup holder main body with a simple structure. When removing the cup holder bottom from the cup holder main body, the above-mentioned hooking can be released by pushing the cup holder bottom upward relative to the cup holder main body.

[0010] The armrest of the third aspect is the armrest of the second aspect, in which the cup holder bottom is inverted upside down and inserted into the cup holder main body from above the armrest with the bottom flange positioned at the lower end, so that the bottom flange hooks onto the main body flange from above the armrest.

[0011] In the armrest of the third aspect, the cup holder bottom is inverted as described above, and the bottom flange located at the lower end is hooked onto the main body flange from above the armrest, so that it is attached to the cup holder main body in an inverted state. This allows the cup holder bottom to be raised above the armrest, making it easier to hold small items such as smartphones.

[0012] The armrest of a fourth aspect is the armrest of the second or third aspect, in which a fitting portion formed on the bottom flange fits into a fitted portion formed on the main body flange.

[0013] In the armrest of the fourth aspect, a fitting portion formed on the bottom flange of the cup holder bottom fits into a mating portion formed on the main body flange of the cup holder main body, thereby preventing the cup holder bottom from accidentally coming off the cup holder main body.

[0014] A vehicle seat of the fifth aspect comprises a seat cushion on which a vehicle occupant sits, a seat back that supports the back of the occupant, and an armrest of any one of the first to fourth aspects, in which the armrest main body portion is attached to the seat back.

[0015] In the vehicle seat of the fifth aspect, the back of an occupant seated on a seat cushion is supported by a seat back. An armrest main body provided with an armrest is attached to the seat back. This armrest is one of the first to fourth aspects, and therefore the above-mentioned effects can be obtained. [Effects of the Invention]

[0016] As described above, the armrest and vehicle seat according to the present invention can stably hold cups of various sizes. [Brief explanation of the drawings]

[0018] A vehicle seat 10 according to one embodiment of the present invention will be described below with reference to Figures 1 to 14. Note that in each figure, some reference numerals may be omitted to make the drawings easier to understand.

[0019] As shown in Fig. 1, the vehicle seat 10 according to this embodiment is a rear seat for seating three passengers, and includes a seat cushion 12 on which vehicle occupants sit, a seat back 14 that supports the backs of the occupants, and three headrests 16 that support the heads of the occupants. The arrows FR, RH, and UP shown in Fig. 1 indicate the front, right, and top of the vehicle seat 10, respectively. Hereinafter, when the front-rear, left-right, top-bottom directions are used in the description, they will indicate directions relative to the vehicle seat 10.

[0020] The seatback 14 is, for example, a 6:4 split folding type, and is divided into a right seatback 14R for two-seater use and a left seatback 14L for one-seater use. Two headrests 16 are attached to the upper end of the right seatback 14R, and one headrest 16 is attached to the upper end of the left seatback 14L.

[0021] An armrest 20 according to this embodiment is attached to the left side of the right seatback 14R. The armrest 20 is rotatable relative to the right seatback 14R between an unfolded position shown in Fig. 1 and a stored position where it is stored in a recess 18 formed in the left side of the right seatback 14R.

[0022] When the armrest 20 is in the extended position, the front-rear, left-right, up-down directions of the armrest 20 coincide with the front-rear, left-right, up-down directions of the vehicle seat 10. When the armrest 20 is in the stowed position, the front-rear direction of the armrest 20 coincides with the height direction of the seat back 14, the left-right direction of the armrest 20 coincides with the left-right direction of the vehicle seat 10, and the up-down direction of the armrest 20 coincides with the front-rear direction of the seat back 14. Hereinafter, when the front-rear, left-right, up-down directions are used to describe the armrest 20, these directions refer to the armrest 20 in the extended position.

[0023] 2 to 7, the armrest 20 includes an armrest main body 22 rotatably attached to the right seat back 14R, and a cup holder 50 attached to the armrest main body 22. The armrest main body 22 includes a trim cover 24 (see FIG. 4) which is a surface layer, a pad 30 (see FIG. 5) which is a cushioning material, and a frame 34 (see FIGS. 6 and 7) which is a framework member. Note that in FIGS. 2 to 14, the arrows FR, UP, and RH indicate the directions when the armrest 20 is in the deployed position.

[0024] The trim cover 24 is formed into a bag-like shape by sewing together multiple pieces of fabric, leather, synthetic leather, or the like. The pad 30 is formed from a foam such as urethane foam and has a long rectangular parallelepiped shape with its length extending in the front-to-rear direction, its width extending in the left-to-right direction, and its thickness extending in the vertical direction of the armrest. The trim cover 24 is placed over the pad 30.

[0025] A cup holder accommodating hole 32 is formed in the front part of the pad 30, penetrating the pad 30 in the vertical direction, and the trim cover 24 is formed so that the cup holder accommodating hole 32 opens in the vertical direction of the armrest 20. The pad 30 is formed by integral foam molding with a frame 34, for example, and the frame 34 is embedded within the pad 30.

[0026] The frame 34 has a pipe frame 36 made of a bent metal pipe material, a pair of left and right rear brackets 38 made of a press-formed metal plate material, and an intermediate frame 40 made of a bent metal wire material. In Figures 6 and 7, 42 denotes an insert wire embedded in the pad 30.

[0027] The pipe frame 36 has a rectangular frame shape with its longitudinal direction extending in the front-to-rear direction of the armrest when viewed from the top-to-bottom direction of the armrest. The left and right rear brackets 38 are disposed at the rear of the armrest 20 and are fixed to the pipe frame 36 by means of welding or the like.

[0028] Connecting shafts 44 that protrude outward in the left-right direction of the armrest are fixed to the rear ends of the left and right rear brackets 38. The left and right connecting shafts 44 are cylindrical with their axial direction aligned with the left-right direction of the armrest and are arranged coaxially. The left and right connecting shafts 44 are rotatably supported by a frame (not shown) of the right seat back 14R. This allows the frame 34, i.e., the armrest main body 22, to be connected to the right seat back 14R so as to be rotatable around the left and right connecting shafts 44. In Figures 6 and 7, reference numeral 46 denotes a stopper pin that limits the rotation range of the armrest main body 22 relative to the right seat back 14R.

[0029] Intermediate frame 40 is disposed in the front-to-rear intermediate portion of armrest 20 with its longitudinal direction aligned with the left-to-right direction of the armrest, and is fixed to pipe frame 36 by means of welding or the like. As shown in Figure 6, cup holder main body 52, which constitutes the main body of cup holder 50, is disposed between the front end of pipe frame 36 and intermediate frame 40.

[0030] Cup holder 50 is composed of cup holder main body 52 and cup holder bottom 68 detachably attached to cup holder main body 52. ​​Cup holder main body 52 is fitted into cup holder accommodating hole 32 (see FIG. 5) formed in the front part of pad 30. Cup holder accommodating hole 32 is open on both sides in the vertical direction. Openings 26 and 28 are formed in trim cover 24 at the location where cup holder main body 52 is provided.

[0031] As shown in Figure 8, cup holder main body 52 is manufactured by, for example, resin injection molding, and has a cylindrical shape that is open on both the top and bottom sides and is longitudinal in the left-right direction. An engagement portion (not shown) that engages with the front end of pipe frame 36 is provided on the front surface of cup holder main body 52, and two engagement portions 54 (left and right) that engage with intermediate frame 40 are provided on the rear surface of cup holder main body 52. ​​In this way, cup holder main body 52 is fixed to frame 34.

[0032] A flange 56 is provided on the edge of the opening at the upper end of the cup holder main body 52. ​​The flange 56 extends from the edge of the opening of the cup holder main body 52 to both sides in the front-to-rear direction and both sides in the left-to-right direction. The flange 56 covers the edge of the upper opening of the cup holder accommodating hole 32 in the pad 30. Although the trim cover 24 is not shown in Figure 10, the edge of the opening 26 of the trim cover 24 is sandwiched between the flange 56 and the pad 30.

[0033] A pair of front and rear partitions 58 are formed in the center of the cup holder main body 52 in the left-right direction. This divides the cup holder main body 52 into two left and right holder sections 60, allowing two beverage containers to be held side by side in the left-right direction. Each holder section 60 is generally cylindrical with its axis extending vertically. A main body flange 62 is formed at the lower end of each holder section 60, extending radially inward of the holder section 60 (i.e., toward the inside of the cup holder main body 52).

[0034] 9, cup holder bottom 68 is made up of a pad portion 72 covered with a skin 70 (not shown in FIG. 10) and a resin plate 74 attached to the upper surface of pad portion 72. Skin 70 is made of the same material as trim cover 24, pad portion 72 is made of the same material as pad 30, and resin plate 74 is made of, for example, injection-molded resin.

[0035] This cup holder bottom 68 has two left and right bottom plate portions 76 that close the lower end openings of each holder portion 60, and a connecting portion 78 that connects the left and right bottom plate portions 76 in the left-right direction. The left and right bottom plate portions 76 are cylindrical with their axis directed vertically. The lower end of the cup holder accommodating hole 32 has the same shape as the cup holder bottom portion 68 when viewed from the vertical direction, and the cup holder bottom portion 68 is configured to fit into the lower end of the cup holder accommodating hole 32.

[0036] Resin plate 74 is formed slightly larger than pad portion 72 when viewed in the vertical direction, and its outer periphery protrudes outward from pad portion 72. As a result, a bottom flange 80 (see FIG. 10) is provided at the upper end of cup holder bottom 68, which hooks from above onto main body flange 62 of cup holder main body 52. ​​This hook prevents cup holder bottom 68 from falling downward from the lower end of cup holder main body 52.

[0037] As shown in Figures 10 and 11, a plurality of holes 64 are formed in the main body flange 62 of the cup holder main body 52. ​​The plurality of holes 64 are arranged at intervals in the circumferential direction of each holder portion 60. The plurality of holes 64 are formed in a circular shape, for example. A plurality of protrusions 82 that protrude downward are formed on the underside of the bottom flange 80 corresponding to the plurality of holes 64. The plurality of protrusions 82 are arranged at intervals in the circumferential direction of each bottom plate portion 76. For example, each protrusion 82 has a cylindrical shape with its axis extending in the up-down direction. The plurality of protrusions 82 fit into the plurality of holes 64, thereby engaging the cup holder bottom 68 with the cup holder main body 52. ​​The protrusions 82 correspond to the "fitting portion" in this invention, and the holes 64 correspond to the "fitted portion" in this invention.

[0038] In the vehicle seat 10 configured as described above, the back of an occupant seated on the seat cushion 12 is supported by the seat back 14. An armrest main body 22, which is the main body of the armrest 20, is attached to the right seat back 14R. A cup holder main body 52, which constitutes the main body of the cup holder 50, is provided in front of the armrest main body 22. The cup holder main body 52 is tubular and opens on both sides of the armrest main body 22 in the vertical direction.

[0039] A cup holder bottom 68 is attached to the lower end of the cup holder main body 52. ​​When the cup size of this armrest 20 is normal or small, it can be used as usual with the cup holder bottom 68 attached to the lower end of the cup holder main body 52. ​​When the cup size is large, the cup holder bottom 68 can be removed from the lower end of the cup holder main body 52 and the cup can be fitted into the cup holder main body 52. ​​This allows cups of various sizes to be held stably.

[0040] That is, as shown in FIG. 12, if a large cup C (for example, a 30-ounce tumbler) is held in cup holder 50 with cup holder bottom 68 attached to the lower end of cup holder main body 52, the center of gravity of cup C will be high and unstable, making the cup C unsteady while the vehicle is moving. In such a case, as shown in FIG. 13, cup holder bottom 68 can be removed from the lower end of cup holder main body 52 and the cup can be fitted into cup holder main body 52 for use. This allows cup C to be stably held while the vehicle is moving, making it possible to accommodate cups of various sizes. Moreover, because it is only necessary to divide the bottom of the cup holder in an existing armrest, it is possible to avoid major design changes or enlarging the armrest.

[0041] Furthermore, in this armrest, bottom flange 80 provided at the upper end of cup holder bottom 68 hooks onto main body flange 62 provided at the lower end of cup holder main body 52. ​​This makes it possible to hold cup holder bottom 68 in cup holder main body 52 with a simple configuration. When removing cup holder bottom 68 from cup holder main body 52, the above-mentioned hooking can be released by pushing cup holder bottom 68 upward toward armrest main body 22 relative to cup holder main body 52, making it easy to remove cup holder bottom 68.

[0042] Furthermore, in this armrest 20, multiple protrusions 82 formed on bottom flange 80 of cup holder bottom 68 fit into multiple holes 64 formed on main body flange 62 of cup holder main body 52. ​​This makes it possible to prevent cup holder bottom 68 from accidentally coming off cup holder main body 52.

[0043] Next, a modified example of this embodiment will be described with reference to Fig. 14. In this modified example, as shown in Fig. 14, cup holder bottom 68 is turned upside down and inserted into cup holder main body 52 from above with bottom flange 80 positioned at the lower end, so that bottom flange 80 hooks onto main body flange 62 from above the armrest.

[0044] The upper surface of bottom flange 80 (the lower surface in FIG. 14 ) is formed with a plurality of protrusions 82 that fit into the plurality of holes 64 of main body flange 62. This fit causes cup holder bottom 68 to engage with cup holder main body 52. ​​In this modified example, cup holder bottom 68 can be used with its height raised upward, making it easier to hold small items such as a smartphone in cup holder 50.

[0045] Although the present invention has been described above with reference to the embodiments, the present invention can be practiced with various modifications without departing from the spirit of the invention. Furthermore, it goes without saying that the scope of the present invention is not limited to the above-described embodiments. [Explanation of symbols]
