Armrest

Abstract

To provide an armrest capable of making a housing member hardly come off from a frame while suppressing deterioration of assemblability of the housing member to the frame.SOLUTION: In a state in which the extension portion 42 of the second engagement portion 40 is elastically deformed with the base portion 41 side as a fulcrum from a state in which the claw portion 43 of the second engagement portion 40 is hooked on the second portion to be engaged 25 and the extension portion 42 is brought into contact with the 31a of the outer peripheral surface of the main body portion 31, there is an engagement margin A in which the claw portion 43 and the second portion to be engaged 25 face each other in the first direction (arrow U-D direction). The engagement margin A makes it difficult for the claw portion 43 to be disengaged from the second engaged portion 25. Since it is not necessary to increase the rigidity of the extending portion 42 in order to make the second engaging portion 40 less likely to come off, it is possible to suppress deterioration of the assemblability of the second engaging portion 40 to the second engaged portion 25 due to the increase in rigidity.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] The present invention relates to an armrest, and more particularly to an armrest that can prevent a housing member from coming off the frame while suppressing deterioration in the ease of assembling the housing member to the frame. [Background technology]

[0002] Armrests constructed by supporting a foam pad on a frame are known, with a recess in the pad accommodating a cup holder or other storage member. In Patent Document 1, the storage member is accommodated in a recess in the upper surface of the armrest, and the storage member is surrounded by the wire of the frame. A first engagement portion that is U-shaped when viewed from the left and right protrudes from the front side of the main body of the storage member, and a hook-shaped second engagement portion is provided on the rear side of the main body. The second engagement portion includes a base portion connected to the main body, an extension portion that extends downward from the base and is positioned rearward away from the main body, and a claw portion that protrudes rearward from the lower end of the extension portion.

[0003] To assemble this housing member to the frame, the U-shaped first engaging portion is fitted onto the wire (first engaged portion), and then the housing member is rotated downward around the first engaging portion, pressing the underside of the claw portion against the wire (second engaged portion).Further downward rotation causes the claw portion to slide against the wire, elastically deforming the extension portion toward the housing member, causing the claw portion to climb over the wire and catch on it, completing the assembly.

[0004] [Patent Document 1] Japanese Patent Publication No. 2023-010766 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned conventional technology, if the extension portion of the second engagement portion has low rigidity, it can be elastically deformed with a small force when assembling the accommodating member to the frame, but the extension portion easily elastically deforms when the accommodating member is pulled upward, making it easy for the claw portion to come off the wire (the accommodating member to come off the frame).In contrast, if the extension portion has high rigidity, it is difficult for the claw portion to come off the wire, but a large force is required when assembling the accommodating member, making it difficult to assemble.

[0006] The present invention has been made to solve the above-mentioned problems, and aims to provide an armrest that can prevent the accommodating member from coming off the frame while suppressing deterioration in the ease of assembling the accommodating member to the frame. [Means for solving the problem]

[0007] In order to achieve this object, the armrest of the present invention comprises a frame, a foam pad supported by the frame, and a storage member accommodated in a recess recessed from an outer surface of the pad toward one side in a first direction, the frame comprising a first engaged portion located on one side of the storage member in a second direction perpendicular to the first direction, and a second engaged portion located on the other side of the storage member in the second direction, the storage member comprising a main body portion having an outer peripheral surface facing an inner peripheral wall surface of the recess, and a pivot provided on the outer peripheral surface and attached to the first engaged portion so as to be rotatable in the first direction around the first engaged portion. and an elastically deformable second engaging portion hooked onto the second engaged portion, wherein the second engaging portion comprises a base connected to the main body, an extension portion extending from the base to one side in the first direction and positioned away from the outer circumferential surface in the second direction, and a claw portion protruding from the extension portion to the side opposite the outer circumferential surface and hooking the second engaged portion onto a surface on the other side in the first direction, and when the extension portion is elastically deformed with the base side as a fulcrum from a state in which the claw portion is hooked onto the second engaged portion and the extension portion is brought into contact with the outer circumferential surface, there is an engagement allowance where the claw portion and the second engaged portion face each other in the first direction. [Effects of the Invention]

[0008] According to the armrest of claim 1, when the claw portion is hooked onto the second engaged portion and the extension portion is elastically deformed around the base portion as a fulcrum, and the extension portion is brought into contact with the outer circumferential surface of the main body, there is an engagement margin where the claw portion and the second engaged portion face each other in the first direction. Therefore, this engagement margin makes it difficult for the claw portion to come off the second engaged portion, almost regardless of the rigidity of the extension portion (even when the extension portion is significantly elastically deformed). Furthermore, since the extension portion does not need to be made highly rigid to make it difficult to come off, it is possible to prevent the deterioration of the ease of assembling the second engaging portion to the second engaged portion that would otherwise be caused by increasing the rigidity. As a result, it is possible to prevent the housing member from coming off the frame while preventing the deterioration of the ease of assembling the housing member to the frame.

[0009] The armrest of claim 2 achieves the following effects in addition to the effects of the armrest of claim 1. When viewed from a third direction perpendicular to the first and second directions, the thickness of the base of the extension side of the claw is 5 mm or more and 10 mm or less. At the base of the base side of the extension, the second moment of area in a cross section perpendicular to the first direction is 100 mm. 4 As a result, the rigidity of the claw portion and the extension portion can be well balanced, making it even more difficult for the accommodating member to come off the frame, and further improving the ease of assembling the accommodating member to the frame.

[0010] The armrest of claim 3 achieves the following effect in addition to the effect achieved by the armrest of claim 1. The second engaged portion is formed in a round bar shape extending in a third direction perpendicular to the first and second directions. The engagement between the claw portion and the second engaged portion is equal to or greater than half the diameter of the second engaged portion. This ensures the engagement, making it more difficult for the storage member to come off the frame.

[0011] The armrest of claim 4 achieves the following effect in addition to the effect achieved by the armrest of any one of claims 1 to 3. Because the length of the extension in the first direction is greater than the length of the base in the first direction, the extension can be easily elastically deformed to bend over its entire length in the first direction during assembly, improving the ease of assembly of the housing member to the frame. On the other hand, because the base is small, stress during elastic deformation of the extension can be easily concentrated on the connection portion between the base and the main body, which may reduce the durability of the connection portion.

[0012] Here, the main body has a flange that protrudes outward from the upper end of the outer peripheral surface. Because the base of the second engagement part is connected to the outer peripheral surface of the main body and the flange, stress applied to the connecting part during elastic deformation of the extension part is more easily dispersed than when the base is connected to only one of the outer peripheral surface or the flange, ensuring the durability of the connecting part. [Brief explanation of the drawings]

[0013] [Figure 1] 1 is a perspective view of a seat provided with armrests in one embodiment. FIG. [Figure 2] FIG. 2 is a cross-sectional view of the armrest taken along line II-II in FIG. [Figure 3] FIG. [Figure 4] 10A and 10B are schematic diagrams showing a method of assembling the housing member to the frame. DETAILED DESCRIPTION OF THE INVENTION

[0014] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Fig. 1 is a perspective view of a seat 10 provided with an armrest 20 in one embodiment. In each drawing, the arrow U direction (the other side of the first direction), the arrow D direction (one side of the first direction), the arrow L direction, the arrow R direction, the arrow F direction (one side of the second direction), and the arrow B direction (the other side of the second direction) indicate the upward, downward, leftward, rightward, forward, and backward directions of the seat 10, respectively. These directions are the same as those seen by a person sitting in the seat 10. The up-down direction (first direction), the left-right direction (third direction), and the front-to-back direction (second direction) are perpendicular to one another.

[0015] The seat 10 is a seat installed in a vehicle (for example, an automobile). The seat 10 mainly comprises a seat cushion 11 that forms the seat surface, a seat back 12 that is rotatably supported by the seat cushion 11 and forms the backrest, and an armrest 20 whose base end is rotatably supported by the seat back 12 and can form an armrest.

[0016] The seat cushion 11 is formed by supporting a cushion pad (not shown) made of a foam such as soft polyurethane foam on a cushion frame (not shown) made of metal or synthetic resin, and covering the cushion pad with a cover material (not shown). In this embodiment, the seat cushion 11 forms a seating surface for two passengers in the rear seats of the vehicle.

[0017] Similarly, the seat back 12 is formed by supporting a back pad (not shown) made of a foam such as soft polyurethane foam on a back frame (not shown) made of metal or synthetic resin, and covering the back pad with a skin material (not shown).

[0018] The seat back 12 in this embodiment can form a backrest for two of the rear seats of the vehicle. Of these two seats, a portion of the backrest for the left seat is formed with an armrest 20 in a stored state that is raised upward from the state shown in FIG. 1. A storage recess 13 for storing this armrest 20 is formed in the front of the seat back 12. The storage recess 13 also opens to the left side surface of the seat back 12.

[0019] 1, the armrest 20 is in use when it is folded down so that it is approximately parallel to the seat cushion 11. In use, the armrest 20 can be placed on the arm of an occupant sitting on the right side of the seat 10 or on a separate seat provided on the left side of the seat 10.

[0020] The armrest 20 will be described below basically using each direction in use. A storage member 30 is embedded in the upper surface of the front end of the armrest 20. In this embodiment, the storage member 30 is a cup holder for receiving and holding a cup for a drink or the like.

[0021] Fig. 2 is a cross-sectional view of armrest 20 taken along line II-II in Fig. 1. Fig. 3 is a bottom view of storage member 30. Armrest 20 is formed by supporting pad 22 made of a foam such as soft polyurethane foam on frame 21 made of metal or synthetic resin, and covering pad 22 with cover material 23.

[0022] An opening 23a into which the storage member 30 is inserted is formed on the upper surface of the skin material 23. Furthermore, a recess 22a is formed in the pad 22 by recessing downward from the upper surface (outer surface) of the pad 22. The storage member 30 is stored in this recess 22a.

[0023] Frame 21 is configured by joining a wire to a frame body by welding or the like, and is embedded in pad 22. The wire is a round metal rod-shaped member that surrounds housing member 30 in recess 22a. The wire has a first engaged portion 24 located in front of housing member 30 and a second engaged portion 25 located in the rear of housing member 30.

[0024] The first engaged portion 24 and the second engaged portion 25 extend parallel to each other in the left-right direction, and their relative positions are fixed. In Fig. 2, the first engaged portion 24 and the second engaged portion 25 are exposed within the recess 22a, but they may be embedded in the pad 22 without being exposed within the recess 22a as long as they are located near the inner circumferential wall surface of the recess 22a.

[0025] The accommodating member 30 includes a main body 31 formed in a generally rectangular cylindrical shape with an open upper end and a closed lower end, a first engaging portion 33 attached to the first engaged portion 24, a restricting portion 34 for preventing the first engaging portion 33 from coming off the first engaged portion 24, and an elastically deformable second engaging portion 40 hooked onto the second engaged portion 25. All of these portions are integrally molded from synthetic resin.

[0026] The main body 31 has an outer peripheral surface 31a facing the inner peripheral wall surface of the recess 22a and facing each of the front, rear, left, and right directions, and a flange 32 extending outward from the entire periphery of the upper end of the outer peripheral surface 31a (main body 31). The flange 32 is a portion that is placed on the upper surface of the skin material 23 so as to close the opening 23a.

[0027] The first engaging portions 33 are portions that protrude from the front side of the outer peripheral surface 31a of the main body 31, and two of them are provided spaced apart in the left-right direction. Each first engaging portion 33 is formed in a U-shape that opens forward when viewed from the left-right direction. The round-bar-shaped first engaged portion 24 is inserted into and attached to the inside of the U-shaped first engaging portion 33. Therefore, when the second engaging portion 40 is not hooked onto the second engaged portion 25, the accommodating member 30 can rotate up and down around the first engaged portion 24.

[0028] The restricting portions 34 are portions that rise substantially vertically from the rear side of the outer peripheral surface 31a of the main body 31, and two of them are provided spaced apart in the left-right direction. The restricting portions 34 are formed to extend downward from the flange 32 and are connected to the outer peripheral surface 31a over their entire length in the up-down direction. The lower edge 34a of the restricting portions 34 is inclined upward as it extends rearward.

[0029] If the second engaging portion 40 is elastically deformed to approach the outer peripheral surface 31a of the main body portion 31 and the accommodating member 30 is moved rearward relative to the first engaged portion 24 and the second engaged portion 25, there is a risk that the first engaging portion 33 will come off the first engaged portion 24. However, before this happens, the second engaged portion 25 comes into contact with the rear end edge of the restricting portion 34, restricting the relative movement of the accommodating member 30 rearward. In this way, the restricting portion 34 can prevent the first engaging portion 33 from coming off the first engaged portion 24.

[0030] The second engagement portions 40 are provided on the rear side of the main body 31, and two of them are provided spaced apart in the left-right direction with the two restriction portions 34 sandwiched between them. Each second engagement portion 40 includes a base 41 connected to the outer circumferential surface 31a and flange 32 of the main body 31, an extension 42 extending downward from the base 41, a claw 43 protruding from the lower end of the extension 42 rearward on the side opposite the outer circumferential surface 31a, and a protrusion 44 protruding rearward from the extension 42 above the claw 43.

[0031] The base 41 has a U-shaped cross section perpendicular to the up-down direction, formed by a pair of left and right side plates 41a that rise approximately vertically from the outer peripheral surface 31a and the underside of the flange 32, respectively, and a connecting plate 41b that connects the rear ends of the side plates 41a. The side plates 41a are flat plates that are perpendicular to the left-right direction, and the connecting plate 41b is a flat plate that is perpendicular to the front-rear direction.

[0032] The extension portion 42 is disposed rearwardly from the outer peripheral surface 31a over the entire length in the vertical direction, and the upper end of the extension portion 42 is connected to the rear side of the lower end of the base portion 41. The extension portion 42 has a U-shaped cross section perpendicular to the vertical direction, formed by an extending side surface plate 42a that extends downward from the side surface plate 41a of the base portion 41, and an extending connecting plate 42b that extends downward from the connecting plate 41b of the base portion 41. The upper half of the extending connecting plate 42b is formed as a flat plate that is perpendicular to the front-to-rear direction, and the lower half is formed as a flat plate that slopes rearward as it extends downward.

[0033] The base of the claw portion 43 is connected to the lower end of the extending connecting plate 42b, and slopes upward from the base to the rear tip. The lower surface of the claw portion 43 is a convex curved surface when viewed from the left and right. The upper surface of the claw portion 43 is a concave curved surface when viewed from the left and right. The thickness of the claw portion 43, which is the dimension from the lower surface to the upper surface, decreases from the base of the claw portion 43 to the tip. In this embodiment, the dimension in the direction parallel to the lower rear surface of the extending connecting plate 42b is defined as the thickness of the claw portion 43.

[0034] The claw portion 43 is hooked onto the second engaged portion 25 so that the second engaged portion 25 abuts against the upper surface of the claw portion 43 and the rear surface of the extended connecting plate 42b of the extension portion 42. This restricts upward rotation of the accommodating member 30 around the first engaged portion 24. Furthermore, with the claw portion 43 hooked onto the second engaged portion 25, the flange 32 is pressed against the upper surface of the pad 22 via the skin material 23, so that downward rotation of the accommodating member 30 is also restricted by the elastic reaction force of the pad 22. As a result, the accommodating member 30 is assembled to the frame 21.

[0035] The protrusion 44 is located above the second engaged portion 25 hooked onto the claw portion 43. When the accommodating member 30 is strongly pressed downward so as to rotate, the protrusion 44 comes into contact with the second engaged portion 25, thereby restricting further downward rotation. As a result, the accommodating member 30 can be prevented from entering too deeply into the recess 22a.

[0036] Next, a method for assembling the accommodating member 30 to the first engaged portion 24 and the second engaged portion 25 (frame 21) will be described with reference to Fig. 4. Fig. 4 is a schematic diagram showing this assembling method, and shows a cross section similar to that of Fig. 2.

[0037] First, with the front side of the accommodating member 30 tilted downward, the first engaging portion 33 is fitted into the first engaged portion 24. Next, the rear side of the accommodating member 30 is rotated downward around the first engaged portion 24, and the lower end of the second engaging portion 40 is brought into contact with the second engaged portion 25.

[0038] Even if the accommodating member 30 attempts to move rearward relative to the first engaged portion 24 before this contact is made, the lower edge 34a of the restricting portion 34 abuts against the second engaged portion 25, thereby restricting the relative movement. This makes it possible to prevent the first engaging portion 33 from coming off the first engaged portion 24 due to the relative movement, and also to prevent the second engaged portion 25 from getting caught between the extending portion 42 and the outer peripheral surface 31a of the main body 31. Furthermore, because the lower edge 34a of the restricting portion 34 is inclined upward toward the rear, it is possible to easily guide the second engaged portion 25 along the lower edge 34a to the lower end of the second engaging portion 40.

[0039] After the lower end of the extension portion 42 of the second engaging portion 40 contacts the second engaged portion 25, the extension portion 42 is pressed against the second engaged portion 25, and the rear side of the accommodating member 30 is rotated further downward. At this time, with the first engaged portion 24 fully inserted into the first engaging portion 33, the lower end of the extension portion 42 that contacts the second engaged portion 25 is inclined upward toward the rear. This inclination continues to the tip of the claw portion 43. Therefore, with further downward rotation, the second engaging portion 40 elastically deforms toward the outer peripheral surface 31a of the main body 31, and the second engaged portion 25 is guided along the inclination to the tip of the sliding claw portion 43. As a result, the claw portion 43 rides over and catches the second engaged portion 25, completing the assembly of the accommodating member 30 to the frame 21.

[0040] 4, the second engaging portion 40 is elastically deformed such that the extending portion 42 is elastically deformed toward the outer peripheral surface 31a (forward) with the base portion 41 side as a fulcrum. Furthermore, the claw portion 43 is elastically deformed such that it is folded upward with the base side as a fulcrum, i.e., toward the extending portion 42 side.

[0041] 2 , if an upward force is applied to the accommodating member 30, for example, when attempting to lift a cup fitted in the accommodating member 30, the rear side of the accommodating member 30 will attempt to rotate upward around the first engaged portion 24. If this upward force is strong, the second engaging portion 40, which is hooked on the second engaged portion 25, will elastically deform. Specifically, as in the case of assembly, the extension portion 42 elastically deforms toward the outer peripheral surface 31a, mainly with the base portion 41 side as a fulcrum. Conversely to the case of assembly, the claw portion 43 elastically deforms downward, with the root side as a fulcrum. If the amount of this elastic deformation becomes large and the hooking between the second engaged portion 25 and the claw portion 43 is released, the accommodating member 30 will come off the frame 21.

[0042] Therefore, if the rigidity of the extension portion 42, which is mainly elastically deformed when the accommodating member 30 is assembled or when the accommodating member 30 is about to be removed, is low, the force required during assembly can be reduced, improving the ease of assembly of the accommodating member 30 to the frame 21. On the other hand, the engagement between the second engaged portion 25 and the claw portion 43 may be more easily released, which may make the accommodating member 30 more likely to come off the frame 21. Conversely, if the rigidity of the extension portion 42 is high, the accommodating member 30 will be less likely to come off, but this may worsen the ease of assembly of the accommodating member 30.

[0043] In contrast, in this embodiment, when the claw portion 43 is disengaged from the second engaged portion 25 after being hooked thereon, the extension portion 42 is elastically deformed around the base portion 41 as a fulcrum and abuts against the outer peripheral surface 31a of the main body portion 31, as shown by the two-dot chain line in FIG. 2 , and the claw portion 43 and the second engaged portion 25 face each other in the vertical direction. Therefore, the engagement amount A makes it difficult for the claw portion 43 to disengage from the second engaged portion 25, almost regardless of the rigidity of the extension portion 42 (even when the extension portion 42 is significantly elastically deformed). Furthermore, since the rigidity of the extension portion 42 is not required to achieve this disengagement, it is possible to prevent deterioration in the ease of assembling the second engaging portion 40 to the second engaged portion 25, which would otherwise be associated with increased rigidity. As a result, it is possible to prevent deterioration in the ease of assembling the housing member 30 to the frame 21 while preventing the housing member 30 from disengaging from the frame 21.

[0044] This engagement allowance A (dimension in the front-rear direction) is equal to or greater than half of the diameter C (dimension in the front-rear direction) of the second engaged portion 25. This ensures an appropriate engagement allowance A for the size of the second engaged portion 25, making it more difficult for the accommodating member 30 to come off the frame 21.

[0045] The vertical length L2 of the extension portion 42 is greater than the vertical length L1 of the base portion 41. Therefore, the extension portion 42 can be easily elastically deformed so as to bend over its entire vertical length during assembly, improving the ease of assembly of the housing member 30 to the frame 21. On the other hand, because the base portion 41 is small, stress during elastic deformation of the extension portion 42 is likely to concentrate on the connection portion between the base portion 41 and the main body portion 31, which may reduce the durability of the connection portion.

[0046] However, in this embodiment, since the base 41 is connected to the outer peripheral surface 31a and flange 32 of the main body 31, the stress applied to the connecting portion during elastic deformation of the extension portion 42 is more easily dispersed than when the base 41 is connected to only one of the outer peripheral surface 31a or the flange 32, and the durability of the connecting portion can be ensured.

[0047] Furthermore, because the extension portion 42 is also formed with a U-shaped cross section so as to extend downward from the U-shaped base portion 41, the extension side plates 42a are more likely to open and the rigidity of the extension portion 42 decreases toward the lower end of the extension portion 42, which is farther from the base portion 41 restrained by the main body portion 31. This allows the extension portion 42 to undergo greater elastic deformation toward the lower end, and suppresses stress concentration at the boundary between the base portion 41 and the extension portion 42 during this elastic deformation. As a result, the durability of the second engagement portion 40 can be improved.

[0048] Since both the upper and lower surfaces of the claw portions 43 are inclined upward toward the rear, when the claw portions 43 climb over the second engaged portions 25 during assembly, the claw portions 43 are likely to elastically deform so as to be folded toward the extending portions 42. This makes it possible to easily hook the claw portions 43 onto the second engaged portions 25 even if the claw portions 43 are made longer for the engagement allowance A. Therefore, the length of the claw portions 43 makes it difficult for the accommodating member 30 to come off the frame 21, while the shape and thickness of the claw portions 43 can improve the ease of assembling the accommodating member 30 to the frame 21.

[0049] Furthermore, as viewed from the left and right, the thickness of the claw portion 43 decreases from the base to the tip, so that the claw portion 43 is more likely to elastically deform in the thickness direction as it approaches the tip. As the lower surface of the claw portion 43 is a convex curved surface that is curved as viewed from the left and right, the claw portion 43 is less likely to bend downward and more likely to bend upward.

[0050] As a result, the claw portions 43 are more easily elastically deformed so as to be folded toward the extension portions 42, and even if the claw portions 43 are made longer, they can be more easily hooked onto the second engaged portions 25. Therefore, the length of the claw portions 43 makes it even more difficult for the accommodating member 30 to come off the frame 21, and the shape and thickness of the claw portions 43 can further improve the ease of assembling the accommodating member 30 to the frame 21.

[0051] As shown in Fig. 4, it is preferable that the thickness T1 of the base of the claw portion 43 is 5 mm or more and 10 mm or less when viewed from the left-right direction. If the thickness T1 is 5 mm or more, the claw portion 43 will not easily come off the second engaged portion 25 even if a force of about 100 N is applied to the accommodating member 30. If the thickness T1 is 10 mm or less, the claw portion 43 can be easily elastically deformed so as to be folded toward the extending portion 42. Therefore, if the thickness T1 is 5 mm or more and 10 mm or less, the accommodating member 30 will not easily come off the frame 21 and the ease of assembling the accommodating member 30 to the frame 21 can be further improved.

[0052] In addition, at the base of the extension portion 42 on the base portion 41 side, the second moment of area in a cross section M perpendicular to the direction in which the extension portion 42 extends (the vertical direction in FIG. 2 in which the housing member 30 is assembled to the frame 21) is 100 mm 4 It is preferable that the length is 300 mm or more. 4 The position of cross section M is below the curve that smoothly connects the base of extension portion 42 to the lower end of base portion 41, and is more preferably the above.

[0053] The second moment of area above is 100mm 4 If the distance is more than 300 mm, the housing member 30 is more unlikely to come off the frame 21. 4 If the second moment of area is 100 mm or more, the housing member 30 is more unlikely to come off the frame 21. 4 As described above, if the thickness T1 is 5 mm or more and 10 mm or less, the rigidity of the claw portion 43 and the extension portion 42 can be well balanced, making it even more difficult for the accommodating member 30 to come off the frame 21, and further improving the ease of assembling the accommodating member 30 to the frame 21.

[0054] While the present invention has been described above based on the above embodiment, it is not limited to the above embodiment, and it is readily apparent that various modifications and improvements are possible without departing from the spirit of the present invention. For example, the shape, dimensions, and number of each part, such as the frame 21, pad 22, and housing member 30, may be appropriately changed. The first engaged part 24 may be a U-shaped member, and the first engaging part 33 may be a round bar-shaped member.

[0055] In the above embodiment, the armrest 20 is rotatably supported on the left side of the seat back 12, but this is not necessarily limited to this. For example, the seat 10 may be reversed left and right, and the armrest 20 may be provided on the right side of the seat back 12. Furthermore, the armrest 20 in the stored state does not necessarily have to form part of the backrest, and the armrest 20 does not have to form part of the backrest. The seat 10 equipped with the armrest 20 may be a front seat or a rear seat of a vehicle, and may be one that is installed in a vehicle other than a vehicle, or one that is not installed in a vehicle.

[0056] In the above embodiment, the case where the storage member 30 is a cup holder has been described, but this is not necessarily limited to this. For example, the storage member 30 may be an ashtray, a small item holder, or an operating device for in-vehicle equipment. Furthermore, the storage member 30 is not limited to being integrally molded, and for example, the main body 31 and the first engaging portion 33 and the second engaging portion 40 may be formed from separate members. Furthermore, part or all of the storage member 30 may be made of metal.
