Description

Technical Field

[0005]

[0001] The present disclosure relates to a vehicle ottoman device, the structure of a vehicle seating device including the vehicle ottoman device, and a control method for the vehicle seating device.

Background Art

[0002] An ottoman device for holding the legs of an occupant sitting on a vehicle seat is used. For example, Patent Document 1 discloses an ottoman device that is attached to the lower part of a seat and enables a leg rest to be deployed forward of the seat and retracted into the lower part of the seat by a four-link mechanism. This ottoman device includes an interlocking extrusion mechanism that extrudes the leg rest forward in conjunction with the deployment operation and retracts the leg rest in conjunction with the retraction operation (see FIGS. 1-4 of Patent Document 1).

[0003] Patent Document 2 discloses a leg rest for a vehicle seat that can store and retrieve a leg rest as needed and can select and hold the position and tilt angle in the front-rear direction of the leg rest from a plurality of stages according to the usage state (see FIGS. 2-3 of Patent Document 2).

[0004] Patent Document 3 discloses an ottoman device in which when the leg rest is taken out to a use position in front of the seat, the leg rest tilts to a position where its front face faces upward in conjunction with this movement operation, and when the leg rest is returned from the use position to the storage position, the leg rest tilts to a standing state where its upper face faces forward and is stored in the seat cushion in conjunction with this (see FIGS. 15-17 of Patent Document 3).

[0005] Patent Document 4 discloses an ottoman device including a link mechanism for moving a leg rest from a storage position to a front operating position, and capable of easily adjusting the posture of the leg rest near the operating position (see FIGS. 1-3 of Patent Document 4).

[0006] <0000Patent Document 5 discloses that the ottoman itself supports the calf and Achilles tendon area of ​​the seated occupant (see Figures 1, 6-11, and 15-17 of Patent Document 5). [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2014-004966 [Patent Document 2] Japanese Patent Application Publication No. 8-308680 [Patent Document 3] Japanese Patent Publication No. 2005-247196 [Patent Document 4] Japanese Patent Publication No. 2013-248109 [Patent Document 5] Japanese Patent Publication No. 2011-250984 [Overview of the project] [Problems that the invention aims to solve]

[0008] Incidentally, conventional ottoman devices have a configuration in which the leg rest is deployed and retracted by a linkage mechanism (for example, a four-point linkage mechanism as described in Patent Document 1), and the trajectory of the deployment and retraction of the leg rest is uniquely determined. For this reason, it is difficult to position the leg rest in a position that is comfortable for occupants of various body types. Furthermore, in conventional ottoman devices (for example, the ottoman devices described in Patent Documents 1 and 3), the leg rest holds the occupant's calf, but this position is not necessarily a position that the occupant finds comfortable.

[0009] Therefore, the purpose of this disclosure is to enable the placement of leg rests in a position that is comfortable for occupants of various body types. [Means for solving the problem]

[0010] The vehicle ottoman device of the present disclosure is a vehicle ottoman device in which a leg rest is movable between a storage position below the seat cushion and an extended position in front of the seat cushion, and is characterized by comprising a sliding mechanism for sliding the leg rest in the front-rear direction, and a tilt mechanism for rotating the sliding mechanism to change the angle of the sliding mechanism with respect to the floor.

[0011] The vehicle ottoman device disclosed herein allows for flexible positioning of the leg rests during deployment and deployment / retraction by operating the sliding mechanism and tilt mechanism separately. Therefore, the leg rests can be positioned in a location that is comfortable for occupants of various body types.

[0012] In the vehicle ottoman device of the present disclosure, the tilt mechanism includes a tilt bracket rotatably mounted on the floor and a tilt drive unit for rotating the tilt bracket, and the slide mechanism may include a guide block attached to the tilt bracket, a rail that slides in the front-rear direction guided by the guide block and to which the foot support is attached at the front end, and a slide drive unit attached to the guide block for driving the rail in the front-rear direction.

[0013] This allows for flexible positioning of the leg supports with a simple configuration.

[0014] The vehicle seating device of the present disclosure comprises a vehicle seat, a vehicle ottoman device, and a control unit for adjusting the operation of the vehicle seat and the vehicle ottoman device, wherein the vehicle seat comprises a position adjustment mechanism for adjusting its position in the front-rear direction and a seat tilt mechanism for moving the front part of the seat cushion up and down, the vehicle ottoman device has a leg rest that is movable between a stowed position at the bottom of the seat cushion and an extended position at the front of the seat cushion, and comprises a slide mechanism for sliding the leg rest in the front-rear direction and a tilt mechanism for rotating the slide mechanism to change the angle of the slide mechanism with respect to the floor, and the control unit is characterized in that it slides the vehicle seat backward using the position adjustment mechanism, and after sliding the vehicle seat backward, raises the front part of the seat cushion using the seat tilt mechanism, and raises the leg rest while sliding it forward using the slide mechanism and the tilt mechanism.

[0015] In this way, by operating the vehicle seat and the ottoman device in conjunction, the leg rest position can be maintained in a position that the occupant finds comfortable when the ottoman device is deployed and when it is deployed / stowed.

[0016] In the vehicle seating device of the present disclosure, the control unit includes an occupant database that stores the physical information of an occupant seated in the vehicle seat, calculates the position of the occupant's knees when seated in the vehicle seat by referring to the occupant database, slides the vehicle seat backward using the position adjustment mechanism so that the front-rear position of the rotation center of the slide mechanism is the front-rear position of the occupant's knees, raises the front of the seat cushion using the seat tilt mechanism, calculates the rotational movement path of the occupant's Achilles tendon centered on the position of the occupant's knees at that time by referring to the occupant database, and slides and raises the leg rest forward using the slide mechanism and the tilt mechanism so that the leg rest moves along the calculated path.

[0017] This can suppress the displacement between the receiving surface of the footrest during the deployment / retraction operation and the legs of the occupant, and the footrest can be deployed / retracted in a state where the occupant feels comfortable. Further, the vicinity of the Achilles tendon where the occupant feels comfortable can be continuously held by the footrest.

[0018] The control method of the vehicle seating device of the present disclosure is a control method of a vehicle seating device including a vehicle seat whose position in the front-rear direction can be adjusted and the front part of the seat cushion can be moved up and down, and a vehicle ottoman device whose footrest can be moved in the front-rear direction and the up-down direction, characterized in that after sliding the vehicle seat backward, the front part of the seat cushion is raised while the footrest is raised while sliding forward.

[0019] This can hold the position of the footrest at a position where the occupant feels comfortable during the deployment of the ottoman device and during the deployment / retraction operation.

Effect of the Invention

[0020] The present disclosure can enable the footrest to be arranged at a position where the occupant feels comfortable for occupants of various physiques.

[Modes for carrying out the invention]

[0022] The vehicle seating device 100 of the embodiment will be described below with reference to the drawings. In the following description, the vehicle seating device 100 will be described as being mounted on the floor 11 of the vehicle so that the occupant 70 faces forward. In this case, the front and rear sides of the vehicle seating device 100 will be the front and rear sides of the vehicle. In each figure, the reference numerals FR, UP, and RH indicate the front, upper, and right sides of the vehicle seating device 100, respectively. The opposite directions of FR, UP, and RH indicate the rear, lower, and left sides. Hereafter, when simply referring to the front-rear, left-right, and up-down directions, unless otherwise specified, they will refer to the front-rear, left-right, and up-down directions of the vehicle seating device 100.

[0023] Furthermore, the vehicle seating device 100 may be mounted on the vehicle floor 11 so that the occupant 70 faces the rear of the vehicle. In this case, the front and rear sides of the vehicle seating device 100 become the rear and front sides of the vehicle.

[0024] As shown in Figures 1 to 3, the vehicle seating device 100 comprises a vehicle seat 10, a vehicle ottoman device 200, and a control unit 60 (see Figure 3).

[0025] The vehicle seat 10 includes left and right seat rails 12L and 12R, a frame 13, a seat cushion 14, a position adjustment mechanism 15, and a seat tilt mechanism 16.

[0026] The left and right seat rails 12L and 12R are longitudinal members attached to the vehicle floor 11 and extending in the front-rear direction. The frame 13 is mounted on the left and right seat rails 12L and 12R so as to be slidable in the front-rear direction. The seat cushion 14 is mounted on the upper part of the frame 13. The position adjustment mechanism 15 is provided between the left and right seat rails 12L and 12R and moves the frame 13 in the front-rear direction. The position adjustment mechanism 15 may consist of a seat slide motor 15M, a worm gear and a screw, etc. (not shown). The seat tilt mechanism 16 is attached to the frame 13 and moves the front part 14A of the seat cushion 14 up and down. The seat tilt mechanism 16 may consist of a seat tilt motor 16M, a worm gear and a screw, etc. (not shown).

[0027] The vehicle ottoman device 200 includes a tilt mechanism 20 and a slide mechanism 30. As shown in Figures 1 and 2, the tilt mechanism 20 includes left and right bases 21L and 21R, a rod 24, left and right round gears 22L and 22R, left and right tilt brackets 23L and 23R, and an ottoman tilt motor 25.

[0028] The left and right bases 21L and 21R are fixed to the left and right seat rails 12L and 12R with bolts 26. The rod 24 is rotatably supported at both ends by the left and right bases 21L and 21R. The left and right round gears 22L and 22R are equipped with tilt gears (not shown) that engage with gears (not shown) provided at the left and right ends of the rod 24 and rotate around the rod 24. The left and right tilt brackets 23L and 23R are connected to the tilt gears in the left and right round gears 22L and 22R and are rotatable around the rod 24. The center of the rod 24 becomes the rotation center 20C of the tilt mechanism 20. The ottoman tilt motor 25 is fixed to the floor 11 and rotates the rod 24. Thus, the ottoman tilt motor 25, the rod 24, and the left and right round gears 22L and 22R constitute the tilt drive unit.

[0029] The sliding mechanism 30 comprises left and right guide blocks 31L and 31R, left and right rails 32L and 32R, a cross frame 33, left and right gearboxes 34L and 34R, left and right screws 35L and 35R, left and right connecting plates 36L and 36R, a shaft 37, an ottoman slide motor 38, left and right leg support brackets 39L and 39R, and a leg support 40.

[0030] The left and right guide blocks 31L and 31R are fixed to the left and right tilt brackets 23L and 23R with multiple bolts 27. The left and right rails 32L and 32R pass through the left and right guide blocks 31L and 31R in the front-to-back direction and slide in the front-to-back direction guided by the left and right guide blocks 31L and 31R. The left and right screws 35L and 35R are positioned parallel to the left and right rails 32L and 32R on the underside of the left and right rails 32L and 32R. The front ends of the left and right screws 35L and 35R are fixed to the front ends of the left and right rails 32L and 32R by the left and right connecting plates 36L and 36R and bolts 41 and 42. The rear ends of the left and right screws 35L and 35R are connected to the rear ends of the left and right rails 32L and 32R.

[0031] The cross frame 33 is a hat-shaped cross section member that connects the left and right tilt brackets 23L and 23R in the left-right direction. The left and right gearboxes 34L and 34R are attached to the left and right ends of the cross frame 33. The shaft 37 is rotatably supported by the left and right gearboxes 34L and 34R. The left and right ends of the shaft 37 are provided with left and right worm gears (not shown) that engage with the left and right screws 35L and 35R. The left and right worm gears are housed in the left and right gearboxes 34L and 34R. The ottoman slide motor 38 is mounted on top of the cross frame 33 and rotates the shaft 37.

[0032] Therefore, the gearboxes 34L and 34R, the left and right screws 35L and 35R, the ottoman slide motor 38, and the shaft 37 constitute the slide drive unit. This slide drive unit is connected to the left and right guide blocks 31L and 31R via the cross frame 33 and the left and right tilt brackets 23L and 23R. Thus, the slide drive unit is mounted on the left and right guide blocks 31L and 31R and drives the left and right rails 32L and 32R in the front and rear directions.

[0033] The left and right leg support brackets 39L and 39R are rotatably attached to the left and right connecting plates 36L and 36R by pins 43L and 43R. The leg support 40 is attached to the top of the left and right leg support brackets 39L and 39R.

[0034] As shown in Figure 3, the control unit 60 is a computer equipped with a CPU 61 that performs information processing internally and a memory 62 that stores control programs and control data. The seat slide motor 15M, the seat tilt motor 16M, the ottoman slide motor 38, and the ottoman tilt motor 25 are connected to the control unit 60 and operate according to commands from the control unit 60. The seat slide motor 15M, the seat tilt motor 16M, and the ottoman slide motor 38 are also equipped with resolvers (not shown) that detect the rotational angle position of the motor shaft, and the output signals of each resolver are input to the control unit 60. In addition, the operation signals of the touchpad 64 operated by the occupant 70 seated in the vehicle seat 10 are input to the control unit 60. The control unit 60 controls the seat slide motor 15M, the seat tilt motor 16M, and the ottoman slide motor 38 based on the output signals of each resolver and the operation signals of the touchpad 64, and adjusts the operation of the vehicle seat 10 and the vehicle ottoman device 200.

[0035] The memory 62 of the control unit 60 stores an occupant database 65, as shown in Figure 4. The occupant database 65 stores the names and physical information of occupants 70 seated in the vehicle seats 10, associating them with each other. The physical information may include, for example, the occupant's height, weight, and sitting height, as shown in Figure 4. However, as will be explained later, the database is not limited to this, as it stores physical information that allows for the calculation of the position of the occupant's knees 71 and the rotational movement path of the Achilles tendon 72 around the rotation center position 73 of the knees 71.

[0036] Next, the basic tilt and slide operations of the vehicle ottoman device 200 will be described. First, the tilt operation will be described. When the rod 24 is rotated by the ottoman tilt motor 25, the tilt gears of the left and right round gears 22L and 22R rotate, causing the left and right tilt brackets 23L and 23R to rotate around the center of the rod 24. This causes the front parts of the left and right tilt brackets 23L and 23R to rotate in the vertical direction.

[0037] As a result, the guide blocks 31L and 31R, which are fixed to the left and right tilt brackets 23L and 23R with bolts 27, rotate vertically, and consequently, the front parts of the left and right rails 32L and 32R rotate vertically. Then, the leg supports 40, which are attached to the front ends of the left and right rails 32L and 32R via the left and right leg support brackets 39L and 39R, rotate vertically. In this way, the entire slide mechanism 30 rotates around the center of the rod 24. Therefore, the center of the rod 24 is both the rotation center 20C of the tilt mechanism 20 and the rotation center 30C of the slide mechanism 30. The tilt mechanism 20 also changes the angle of the slide mechanism 30 with respect to the floor 11.

[0038] Next, the sliding motion will be explained. When the shaft 37 is rotated by the ottoman slide motor 38, the left and right worm gears housed in the gearboxes 34L and 34R rotate. Then, the left and right screws 35L and 35R, which are engaged with the left and right worm gears, move in the front-rear direction. As the left and right screws 35L and 35R move in the front-rear direction, the left and right rails 32L and 32R, which are connected parallel to the left and right screws 35L and 35R, also move in the front-rear direction. Then, the leg supports 40, which are attached to the front ends of the left and right rails 32L and 32R via the left and right leg support brackets 39L and 39R, slide in the front-rear direction.

[0039] The tilt and slide movements described above can be operated separately by the occupant 70 using the touchpad 64 to control the tilt angle and slide amount. This allows the vehicle ottoman device 200 to freely set the position of the leg rest 40 when deployed, as shown in Figure 10. Furthermore, the position of the leg rest 40 during deployment, as shown in Figures 6 to 10, can be freely set. Therefore, the vehicle ottoman device 200 can position the leg rest 40 in a position that the occupant 70 finds comfortable, regardless of their body size.

[0040] Next, the automatic deployment operation of the vehicle ottoman device 200, which is linked to the seat tilt operation of the vehicle seat 10, will be described with reference to Figures 5 to 10. As shown in Figure 6, in the initial state, the left and right rails 32L and 32R of the vehicle ottoman device 200 are parallel to the floor 11 and have moved backward. As a result, the leg supports 40 of the vehicle ottoman device 200 are stored in the storage position below the seat cushion 14.

[0041] As shown in step S101 of Figure 5, when an occupant 70 seated in the vehicle seat 10 operates the touchpad 64 to select automatic deployment of the vehicle ottoman device 200, the CPU 61 of the control unit 60 refers to the occupant database 65 and displays the name of the occupant 70 registered on the touchpad 64. The CPU then waits until the occupant 70 seated in the vehicle seat 10 selects their own name. Once the occupant 70 has selected their name, in step S102 of Figure 5, the CPU 61 refers to the occupant database 65 and calculates the rotation center position 73 of the occupant 70's knee 71. This calculation may, for example, be performed by calculating the amount of sinking of the seat cushion 14 based on the occupant's weight, and then calculating the position of the occupant 70's buttocks from the calculated amount of sinking and the height of the seat cushion 14 of the vehicle seat 10. The position of the knee 71 and the rotation center position 73 of the knee 71 may then be calculated based on the occupant's height, sitting height, and buttock position.

[0042] Next, the CPU 61 of the control unit 60 proceeds to step S103 in Figure 5, and drives the seat slide motor 15M to slide the vehicle seat 10 backward from the initial state shown in Figure 6, as shown by arrow 91 in Figure 7.

[0043] Then, as shown in step S104 of Figure 5 and Figure 7, the CPU 61 of the control unit 60 reduces the rearward movement speed of the vehicle seat 10 when the leg rest 40 is near the Achilles tendon 72 of the occupant 70, and begins to hold the Achilles tendon 72 of the occupant 70 with the leg rest 40.

[0044] Next, the CPU 61 of the control unit 60 moves the vehicle seat 10 backward until the longitudinal position of the rotation center 30C of the slide mechanism 30 is the longitudinal position of the rotation center 73 of the occupant's knee 71, as shown in step S105 of Figure 5 and arrow 92 in Figure 8. If it determines YES in step S105 of Figure 5, the control unit 60 stops the rearward sliding of the vehicle seat 10 in step S106 of Figure 5 and proceeds to step S107 of Figure 5.

[0045] Next, in step S107 of Figure 5, the CPU 61 of the control unit 60 drives the seat tilt motor 16M to raise the front part 14A of the seat cushion 14, as shown by arrow 93 in Figure 9. Then, as shown in step S108 of Figure 5, the CPU 61 of the control unit 60 refers to the occupant database 65 and calculates the rotational movement path 94 of the Achilles tendon 72 centered on the rotation center position 73 of the occupant 70's knee 71. The rotational movement path 94 is a circular arc with radius R centered on the rotation center position 73 of the knee 71, as shown in Figure 9. Here, radius R is the distance from the rotation center position 73 to the Achilles tendon 72.

[0046] Then, the CPU 61 of the control unit 60 proceeds to step S109 in Figure 5, and drives the ottoman slide motor 38 and the ottoman tilt motor 25 to slide the leg rest 40 forward and raise it so that the leg rest 40 moves along the calculated arc-shaped rotational movement path 94. As a result, the lower limbs of the occupant 70 move from the position shown by the dashed line in Figure 9 before the ottoman tilt motor 25 starts to drive to the position shown by the solid line in Figure 9.

[0047] When the front part 14A of the seat cushion 14 is raised, the rotation center position 73 of the occupant's knee 71 moves upward. Therefore, the CPU 61 of the control unit 60 raises the leg support 40 while sliding it slightly forward in step S109 of Figure 5, and if it determines NO in step S110 of Figure 5, it returns to step S107 of Figure 5 and repeats steps S107 to S108. In this way, as shown by arrow 96 in Figure 10, the CPU 61 of the control unit 60 raises the front part 14A of the seat cushion 14, calculates the rotational movement path 97 of the Achilles tendon 72 centered on the position of the rotation center position 73 of the occupant's knee 71, and slides the leg support 40 forward along the calculated rotational movement path 97. As a result, the occupant's lower limb moves from the position shown by the dashed line in Figure 10 to the position shown by the solid line in Figure 10.

[0048] The CPU 61 of the control unit 60 detects the position of the leg rest 40 based on the rotational angle position of the motor shafts input from the resolvers of the ottoman slide motor 38 and the ottoman tilt motor 25. Then, in step S110 of Figure 5, when the position of the leg rest 40 reaches a predetermined deployed position as shown in Figure 10, the CPU 61 determines YES in step S110 of Figure 5 and terminates the automatic deployment operation of the vehicle ottoman device 200.

[0049] As described above, when the vehicle seating device 100 automatically deploys the vehicle ottoman device 200, it operates the vehicle seat 10 and the vehicle ottoman device 200 in conjunction, sliding the vehicle seat 10 backward, then raising the front part 14A of the seat cushion 14, while simultaneously sliding and raising the leg rest 40 forward. This ensures that the leg rest 40 is positioned in a comfortable location for the occupant 70 during the deployment and deployment / retraction of the vehicle ottoman device 200. Furthermore, the vehicle seating device 100 can suppress misalignment between the receiving surface of the leg rest 40 and the occupant 70's legs during deployment / retraction, allowing the leg rest 40 to be deployed / retracted in a comfortable position for the occupant 70. In addition, the leg rest 40 can continuously support the area around the Achilles tendon 72, which is a comfortable position for the occupant 70.

[0050] Furthermore, as explained earlier, the vehicle ottoman device 200 can be operated independently by the occupant 70 using the touchpad 64 to control the tilt angle and slide amount. This allows the vehicle ottoman device 200 to freely set the position of the leg rest 40 when deployed or during deployment / retraction operations. Therefore, the vehicle ottoman device 200 can position the leg rest 40 in a position that the occupant 70 finds comfortable, regardless of their body size. [Explanation of symbols]
