[0003] [Patent Document 1] JP 2006-327329 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-mentioned prior art, in order to slide the armrest body, it is necessary to disengage the cam follower that constitutes the heart cam mechanism from the cam groove. In this case, the armrest body needs to be pulled toward the rear of the seat first, which is not very convenient to use.

[0005] SUMMARY OF THE PRESENT INVETION The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide an armrest and a vehicle seat that are easy to use and whose length in the front-rear direction of the seat can be easily adjusted. [Means for solving the problem]

[0006] The armrest of the first aspect comprises a base member arranged along the fore-and-aft direction of the seat, a slide member provided on the base member and slidable along the fore-and-aft direction of the seat relative to the base member, and a slide mechanism that enables the slide member to slide along the fore-and-aft direction of the seat when a pressing portion provided on the slide member is pressed from above in the up-and-down direction of the seat, and restricts the sliding movement of the slide member when the pressed state of the pressing portion is released.

[0007] The armrest according to the first aspect includes a base member, a slide member, and a slide mechanism. The base member is disposed along the front-rear direction of the seat. The slide member is provided on the base member and is slidable along the front-rear direction of the seat relative to the base member. When a pressing portion provided on the slide member is pressed from above in the up-down direction of the seat, the slide mechanism allows the slide member to slide along the front-rear direction of the seat, and when the pressing portion is released, restricts the sliding movement of the slide member.

[0008] In this manner, in this embodiment, the length of the armrest can be easily adjusted to match the arm length according to the difference in physique by sliding the slide member along the front-rear direction of the seat. Also, in this embodiment, the pressing portion can be pressed from above in the vertical direction of the seat with the wrist while the hand is placed on the armrest. Then, since the slide member can be slid along the front-rear direction of the seat simply by pressing the pressing portion, this is easier to operate and more convenient to use than the comparative example in which the slide member is slid along the front-rear direction of the seat by pulling the slide member rearward in the front-rear direction of the seat.

[0009] The armrest of the second aspect is the armrest of the first aspect, wherein the slide mechanism includes a plurality of engaged portions provided on the base member and formed along the fore-and-aft direction of the seat, and an engaging member provided on the slide member and adapted to engage with or disengage from the engaged portions.

[0010] In the armrest according to the second aspect, the slide mechanism includes a plurality of engaged parts and an engaging member. The engaged parts are provided on the base member and are formed along the front-rear direction of the seat. Meanwhile, the engaging member is provided on the slide member and engages with or disengages from the engaged parts.

[0011] That is, in this embodiment, the engaging member is engaged with the engaged portion, thereby restricting the sliding movement of the slide member, and the engaging member is disengaged (so-called disengagement) to allow the slide member to slide. Here, since a plurality of engaged portions are provided, it is possible to set positions along the front-rear direction of the seat on the slide member in the number of engaged portions. In other words, fine adjustment of the length of the armrest is possible.

[0012] The armrest of the third aspect is the armrest of the first or second aspect, wherein the pressing portion is provided on the upper side of the slide member in the up-down direction of the seat, and the engaging member is supported rotatably around an axis portion arranged along the width direction of the seat, and the engaging member includes a pressing plate arranged on the slide member side and pressed downward in the up-down direction of the seat around the axis portion when the pressing portion is pressed, and an engaging portion arranged on the base member side and rotates upward in the up-down direction of the seat around the axis portion when the pressing plate is pressed downward in the up-down direction of the seat and disengages from the engaged portion.

[0013] In the armrest according to the third aspect, the pressing portion is provided on the upper side of the slide member in the vertical direction of the seat, and the engaging member is supported rotatably around a shaft portion arranged along the width direction of the seat. The engaging member includes a pressing plate and an engaging portion. The pressing plate is arranged on the slide member side, and when the pressing portion is pressed, it is pressed downward in the vertical direction of the seat around the shaft portion. On the other hand, the engaging portion is arranged on the base member side, and when the pressing plate is pressed downward in the vertical direction of the seat, it moves (rotates) upward in the vertical direction of the seat around the shaft portion and is released from engagement with the engaged portion.

[0014] That is, the engaging member includes a pressing plate arranged on the sliding member side and an engaging portion arranged on the base member side, with the shaft portion between them. When the pressing plate is pressed downward in the seat vertical direction via the pressing portion, the engaging portion moves (rotates) upward in the seat vertical direction. As a result, the engaging portion is disengaged from the engaged portion, and the sliding member becomes slidable along the seat front-rear direction.

[0015] On the other hand, when the state in which the pressing portion is pressed (pressing state) is released, the pressing plate moves (rotates) toward the upper side in the vertical direction of the seat, and the engaging portion moves (rotates) toward the lower side in the vertical direction of the seat. As a result, the engaging portion engages with the engaged portion, and the sliding movement of the sliding member is restricted.

[0016] The armrest according to a fourth aspect is an armrest according to any one of the first to third aspects, wherein the slide mechanism has one end provided on the base member side and the other end provided on the slide member side, and further includes a first biasing member that biases the slide member toward the base member side.

[0017] In the armrest according to the fourth aspect, the slide mechanism further includes a first biasing member having one end provided on the base member side and the other end provided on the slide member side, and biases the slide member towards the base member side.

[0018] For this reason, when the slide member is slid forward in the seat front-rear direction, elastic energy is stored in the first biasing member. In this state, when the engaging portion is moved (rotated) upward in the seat up-down direction via the pressing portion to disengage the engaging portion from the engaged portion, the biasing force of the first biasing member enables the slide member to slide backward in the seat front-rear direction (toward the base member).

[0019] The armrest according to the fifth aspect is an armrest according to any one of the first to fourth aspects, wherein the engaging member is provided with a second biasing member which biases the engaging member in a direction to engage the engaging portion with the engaged portion.

[0020] In the armrest according to the fifth aspect, the engaging member is provided with a second biasing member. The second biasing member biases the engaging member in a direction in which the engaging portion engages with the engaged portion, thereby maintaining the state in which the engaging member is engaged with the engaged portion.

[0021] When the pressing portion provided on the slide member is pressed, the pressing plate is pressed downward in the vertical direction of the sheet via the pressing portion, and the engaging portion is disengaged from the engaged portion. In this embodiment, the engaging member is urged in a direction in which the engaging portion engages with the engaged portion by the second urging member provided on the engaging member, so that elastic energy is accumulated in the second urging member while the pressing portion is being pressed. Therefore, when the pressing state of the pressing portion is released, the pressing force of the second urging member causes the pressing plate to move (rotate) upward in the vertical direction of the sheet and return to its original state.

[0022] The armrest of the sixth aspect is an armrest of any one of the first to fifth aspects, wherein a front end of the sliding member in the seat fore-and-aft direction is provided with an operation panel that is connected to a vehicle ECU mounted in the vehicle and can operate devices connected to the vehicle ECU.

[0023] In the armrest according to the sixth aspect, an operation panel is provided at the front end of the sliding member in the seat front-rear direction. This operation panel is connected to a vehicle ECU mounted on the vehicle, and can operate devices connected to the vehicle ECU. This makes it possible to operate, for example, the devices connected to the vehicle ECU, such as the seat sliding, reclining, vehicle air conditioning, audio, and navigation systems.

[0024] The armrest of the seventh aspect is an armrest of any one of the first to sixth aspects, wherein the device is at least a sliding device that slides the vehicle seat along the front-to-rear direction of the seat and a reclining device that tilts the seat back.

[0025] In the armrest of the seventh aspect, the devices connected to the vehicle ECU are at least a sliding device and a reclining device, and the operation panel provided at the front end of the armrest allows the vehicle seat to be slid or reclined while the user places their hands on the armrest, which is convenient.

[0026] A vehicle seat according to an eighth aspect is provided with the armrest according to any one of the first to seventh aspects.

[0027] In the vehicle seat according to the eighth aspect, it is possible to enjoy the effects obtained by using the armrest according to any one of the first to seventh aspects. Effect of the Invention

[0028] As described above, according to the armrest of the present invention, the length in the fore-aft direction of the seat can be easily adjusted, and the usability of the armrest body can be improved. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In each drawing, the arrow UP indicates the seat upper direction, the arrow FR indicates the seat front direction, and the arrow RH indicates the seat right direction. In other words, in the following description, when the up-down, front-rear, and left-right directions are described without special mention, the up-down, front-rear, and left-right directions are based on the up-down, front-rear, and left-right directions of the vehicle seat 10 shown in FIG. 1. In addition, the short side direction described later is synonymous with the left-right direction.

[0031] (Armrest configuration) First, the configuration of the armrest according to this embodiment will be described.

[0032] As shown in Figures 5(A) and (B), a vehicle seat 10 provided in a vehicle (not shown) has a seat cushion 12 on which an occupant sits (supporting the occupant's thighs and buttocks), a seat back 14 that supports the occupant's back, a headrest (not shown) that supports the occupant's head, and an armrest 16 that supports the occupant's forearm (mainly from the elbow to the wrist).

[0033] As shown in Figures 5(A) and (B), the armrest 16 is provided on the right side of the vehicle seat 10 and is fixed, for example, to the tip of an arm 15 extending in the up-down direction of the seat cushion 12.

[0034] In this embodiment, the armrest 16 is provided on the right side of the vehicle seat 10, but may be provided on the left side of the vehicle seat 10, or may be provided on the left or right side of the vehicle seat 10. In this embodiment, the armrest 16 is fixed to an arm 15 fixed to the seat cushion 12, but this is not limited thereto. For example, although not shown, the armrest 15 may be fixed to the vehicle body floor. Alternatively, the armrest 16 may be provided directly on the seat back 14 side.

[0035] As shown in FIG. 1, the armrest 16 of this embodiment is configured to include a base frame (base member) 18 with its longitudinal direction aligned with the fore-and-aft direction of the seat, and a subframe (slide member) 20 provided on a front portion 22 of the base frame 18.

[0036] 2, the base frame 18 is generally box-shaped with an opening on the upper side, and the sub-frame 20 is generally box-shaped with openings on the upper and rear sides. As described above, the sub-frame 20 is provided on the front part 22 of the base frame 18.

[0037] For this reason, the height of the front wall 18A of the base frame 18 and the pair of side walls 18B on the front 22 side of the base frame 18 are formed to be lower than the height of the rear wall 18C of the base frame 18 and the side walls 18D on the central portion 24 and rear 26 sides of the base frame 18. A rectangular plate-shaped top cover 28 is fixed to the upper ends of the rear wall 18C and side walls 18D of the base frame 18.

[0038] A pair of angles 32 supporting a power spring (first biasing member) 30 wound around an axis along the width direction of the armrest 16 are fixed to the rear 26 of the bottom wall portion 18E of the base frame 18 at the center along the width direction of the armrest 16.

[0039] In addition, at both ends of the armrest 16 in the width direction, a rack member 34 is provided in the central portion 24 of the bottom wall portion 18E of the base frame 18, and constitutes part of the slide mechanism 35. The rack member 34 has a plurality of plate-shaped engaged portions 34A arranged along the longitudinal direction of the base frame 18.

[0040] Furthermore, a slide unit 36 ​​is fixed along the front-rear direction of the seat to the front part 22 of the bottom wall part 18E of the base frame 18 at the center in the width direction of the armrest 16. The slide unit 36 ​​has a substantially rectangular parallelepiped shape, and a substantially rectangular parallelepiped-shaped protrusion 36A is provided to protrude from the center in the width direction of the slide unit 36.

[0041] Here, a slide portion 38 having a recess (not shown) formed therein that engages with the protrusion 36A is protruded from the underside of the bottom wall portion 20A of the subframe 20. The slide portion 38 is engaged with the slide unit 36, whereby the subframe 20 is made slidable along the longitudinal direction of the base frame 18 via the slide portion 38 and the slide unit 36.

[0042] In a state in which the sub-frame 20 is engaged with the base frame 18, the heights of the side walls 20B of the sub-frame 20 and the side walls 18D of the base frame 18 are set to be substantially the same.

[0043] A generally rectangular top cover 42 is fixed to the upper end of the side wall portion 20B of the subframe 20. An opening 42A having an elliptical shape is formed in the center of the top cover 42 in the longitudinal direction of the armrest 16. A pressing pad (pressing portion) 44 made of, for example, urethane can be inserted into this opening 42A, allowing the pressing pad 44 to be pressed.

[0044] An operation panel 46 is provided on the front end of the top cover 42. The operation panel 46 is provided with an operation unit that is connected to, for example, a vehicle ECU 56 (see FIG. 5(A)) and that slides the seat cushion 12 in the front-rear direction of the seat and reclines the seat back 14. The operation panel 46 is disposed so as to incline upward as it approaches the front side of the armrest 16, and is configured to be easy for the occupant to operate.

[0045] Meanwhile, a rotating shaft (shaft portion) 40 is fixed along the width direction of the armrest 16 to the upper side of the rear end portion of the side wall portion 20B of the subframe 20. A lock unit (engagement member) 48 which constitutes another part of the slide mechanism 35 is supported on the rotating shaft 40 so as to be rotatable (pivotable).

[0046] The lock unit 48 includes a pressing plate 50 and an engaging portion 52. The pressing plate 50 is provided on the front side of the lock unit 48, and is disposed on the subframe 20 side. On the other hand, the engaging portion 52 is provided on the rear end portion of the lock unit 48, and is disposed on the base frame 18 side.

[0047] The pressure plate 50 is formed in a rectangular plate shape and is disposed substantially horizontally below the pressure pad 44. When the pressure pad 44 is pressed, the pressure plate 50 moves downward around the rotating shaft 40. The tip of the power spring 30 is fixed by a screw or the like to the center of the pressure plate 50 in the width direction of the armrest 16, and the pressure plate 50 and the rotating shaft 40 bias the subframe 20 toward the base frame 18 (toward the rear of the seat).

[0048] Furthermore, a linear member 54 having a substantially rectangular frame shape extends from both ends of the pressure plate 50 in the width direction of the armrest 16. This linear member 54 is inclined downward as it approaches the rear side of the pressure plate 50, and an engagement portion 52 is provided at the tip of the linear member 54, and the engagement portion 52 is bent so as to be substantially parallel to the pressure plate 50. This engagement portion 52 is capable of engaging with the engaged portion 34A of the rack member 34.

[0049] The linear member 54 has three bending points 54A, 54B, and 54C, and the bending point 54A is provided at a location where the rotating shaft 40 is disposed. Although not shown, for example, a support portion through which the rotating shaft 40 can be inserted is formed at the bending point 54A, and the rotating shaft 40 passes through the support portion. The lock unit 48 is rotatably supported via the rotating shaft 40. The bending points 54B and 54C are formed in accordance with the height dimension of the engaged portion 34A, and the distance between the two is set so that the engaging portion 52 is engaged with the engaged portion 34A.

[0050] On the other hand, a torsion spring (second biasing member) (not shown) is provided on the rotating shaft 40. One end of the torsion spring is connected to the support portion, and the other end of the torsion spring is connected to the side wall portion 20B of the subframe 20, and the torsion spring biases the lock unit 48 in a direction to engage the engaging portion 52 with the engaged portion 34A. In other words, when the state in which the pressing pad 44 is pressed (pressing state) is released, the pressing plate 50 moves upward around the rotating shaft 40, and the engaging portion 52 engages with the engaged portion 34A.

[0051] (Action and effect of armrest) Next, the function and effect of the armrest according to this embodiment will be described.

[0052] As shown in FIG. 2, in this embodiment, the armrest 16 includes a base frame 18, a subframe 20, and a slide mechanism .

[0053] The base frame 18 is disposed along the front-rear direction of the seat, and the subframe 20 is provided on the base frame 18 and is slidable along the front-rear direction of the seat relative to the base frame 18. In addition, the slide mechanism 35 allows the subframe 20 to slide along the front-rear direction of the seat when a push-in pad 44 provided on the subframe 20 is pressed, and restricts the sliding movement of the subframe 20 when the pressed state of the push-in pad 44 is released (described later).

[0054] In this manner, in this embodiment, as shown in Figures 5(A) and (B), the length of the armrest 16 can be easily adjusted to suit arm lengths according to differences in physique by sliding the subframe 20 along the fore-aft direction of the seat.

[0055] In this embodiment, the push-in pad 44 can be pressed from above with the wrist while the hand is placed on the armrest 16. Then, the subframe 20 can be slid along the seat front-rear direction simply by pressing the push-in pad 44 from above. For this reason, in this embodiment, the armrest 16 can be easily operated and is convenient to use, as a comparative example (not shown) in which the subframe 20 is slid along the seat front-rear direction by pulling it rearward in the seat front-rear direction.

[0056] Here, the slide mechanism 35 will be specifically described.

[0057] 2, in this embodiment, the slide mechanism 35 includes a plurality of engaged parts 34A and a lock unit 48. The plurality of engaged parts 34A are provided on the base frame 18 and are formed along the front-rear direction of the seat. On the other hand, the lock unit 48 is provided on the subframe 20 side, and an engaging part 52 constituting a part of the lock unit 48 is disposed on the base frame 18 side and is capable of engaging with or disengaging from the plurality of engaged parts 34A.

[0058] In this embodiment, as shown in Figures 6 and 8, the engaging portion 52 engages with the engaged portion 34A, thereby restricting the sliding movement of the subframe 20, and as shown in Figure 7, the engaging portion 52 is disengaged (so-called disengagement), thereby enabling the subframe 20 to slide.

[0059] In this embodiment, the pressing pad 44 is provided on the upper side of the subframe 20, and the locking unit 48 is supported rotatably around a rotating shaft 40 disposed along the seat width direction.

[0060] The pressure plate 50 is disposed on the subframe 20 side, and when the pressing pad 44 is pressed, the pressure plate 50 is pressed downward about the rotating shaft 40. On the other hand, the engagement portion 52 is disposed on the base frame 18 side, and when the pressure plate 50 is pressed downward, it moves upward about the rotating shaft 40 and disengages the engagement portion 52 from the engaged portion 34A. This allows the subframe 20 to slide along the front-rear direction of the seat.

[0061] In this embodiment, a torsion spring (not shown) is provided on the rotating shaft 40, and the torsion spring biases the lock unit 48 in a direction that causes the engaging portion 52 to engage with the engaged portion 34A when the pressing plate 50 is disposed substantially horizontally as shown in Fig. 6. In other words, the engaging portion 52 engages with the engaged portion 34A, and the sliding movement of the subframe 20 is restricted.

[0062] 7, when the pressing plate 50 is pressed via the pressing pad 44, elastic energy is stored in the torsion spring. Therefore, when the pressing state (pressing state) against the pressing pad 44 is released, the pressing plate 50 moves upward by the biasing force of the torsion spring and returns to its original state, and the engaging portion 52 moves downward. As a result, the engaging portion 52 engages with the engaged portion 34A, and the sliding movement of the subframe 20 is restricted.

[0063] In this embodiment, since a plurality of engaged portions 34A are provided, it is possible to set positions along the front-rear direction of the seat on the subframe 20 in accordance with the number of engaged portions 34A provided. In other words, fine adjustment of the length of the armrest 16 is possible.

[0064] Meanwhile, in this embodiment, the slide mechanism 35 is configured to further include a power spring 30, as shown in Fig. 4. This power spring 30 is provided on the base frame 18 side, and a tip portion of the power spring 30 is fixed to a pressure plate 50 of a lock unit 48 provided on the subframe 20 side, and biases the subframe 20 toward the base frame 18 side via the pressure plate 50 and the rotating shaft 40.

[0065] 8, when the subframe 20 slides forward, elastic energy is stored in the spiral spring 30. In this state, when the engaging portion 52 is moved upward via the push-in pad 44 to disengage the engaging portion 52 from the engaged portion 34A, the subframe 20 becomes slidable in the front-rear direction. At this time, the biasing force of the spiral spring 30 enables the subframe 20 to slide toward the base frame 18 (rearward).

[0066] With the above-described configuration, in this embodiment, the pressure plate 50 is pressed downward via the pressing pad 44 provided on the subframe 20, disengaging the engaging portion 52 from the engaged portion 34A, thereby enabling the subframe 20 to move.

[0067] At this time, when the subframe 20 slides forward, elastic energy is further stored in the spiral spring 30. In this way, because elastic energy is stored in the spiral spring 30, when the subframe 20 slides rearward, it becomes possible for the subframe 20 to slide toward the base frame 18 (rearward) due to the biasing force of the spiral spring 30.

[0068] However, when moving the subframe 20, it is necessary to disengage the engaging portion 52 from the engaged portion 34A, and therefore it is necessary to maintain the pressure plate 50 pressed downward via the pressing pad 44.

[0069] 5(A), in this embodiment, an operation panel 46 is provided on the front end portion of the subframe 20. The operation panel 46 is provided with an operation unit (not shown) that is connected to the vehicle ECU 56 and is connected to a device that slides the seat cushion 12 in the front-rear direction of the seat and reclines the seat back 14.

[0070] In this embodiment, the operation panel 46 is disposed so as to incline upward as it approaches the front side of the armrest 16, making it easy for the occupant to operate it. This allows the occupant to conveniently operate the seat cushion 12 and the seat back 14 while maintaining a seated position and resting their hands on the armrest 16.

[0071] The operating unit may be connected to devices that operate the air conditioner, audio, navigation system, etc., connected to the vehicle ECU 56, in addition to devices that operate the seat cushion 12 and the seat back .

[0072] As described above, the armrest 16 of the vehicle seat 10 according to this embodiment has been described based on the drawings. However, the armrest 16 of the vehicle seat 10 according to this embodiment is not limited to the one shown in the drawings, and the design can be modified as appropriate within the scope that does not deviate from the gist of the present invention.
