Description

  The present invention relates to a seat control device that controls an operation of changing the state of a seat, and is applied to, for example, a seat mounted on various vehicles such as railway cars, automobiles, aircraft, and ships.

  2. Description of the Related Art Conventionally, there are many seat types that can be hung by a plurality of people on seats mounted on vehicles such as railway vehicles. Such seats are generally arranged side by side in a row on both sides in the front-rear (advancing) direction in a passenger compartment of a vehicle. Here, for each seat, there is known a rotary seat that can be turned to be turned into a long state that is horizontal to the front-rear direction, a one-cross state that is forward, and a reverse cross state that is backward. There is.

  As such a rotary seat, in addition to mechanisms for rotating or sliding the seat, a transmission mechanism is provided, and a device that interlocks rotation and sliding of the seat by the transmission mechanism when turning the seat is known (for example, Patent Document 1). In such a device, the slide base is slidably supported on the fixed base, the seat is rotatably supported on the slide base, and rotation and sliding of the seat are interlocked by the transmission mechanism. After the series of actions for one seat were performed, the same action was repeated for the next seat.

Patent No. 3431772

  However, with the technology described in Patent Document 1 described above, it has not been possible to simultaneously change the direction of a plurality of seats. That is, a series of switching operations must be performed sequentially for each seat, which takes a very long time to complete the turning of all the seats, which may hinder the operation of the vehicle.

  In addition, in the case where individual passengers can arbitrarily manually turn as well as electrically turn, not all seats are uniformly in the same direction at the time of electrically operated. Therefore, it is usually necessary to determine the direction individually for each seat after determining which direction it is. As a result, the number of parts such as sensors for determining all the directions for each seat increases, the control program becomes complicated, and the cost increases.

  The present invention has been made focusing on the problems of the prior art as described above, and the control for converting the state of the seat is simplified, and a plurality of seats can also be converted at once. An object of the present invention is to provide a seat control device capable of easily controlling the conversion operation by a simple program and parts and capable of reducing the cost.

Is uniformly rotated, but the conversion of the seat (1) due to the rotation of the motor (42) is prevented by the stoppers (16, 17). The seat control apparatus (100) as described in 1 ] .

[ 3 ] There are a plurality of the seats (1), and the conversion mechanism (10) and the drive means (42) are provided for each seat (1),
The control means (110) is to convert all the seats (1) simultaneously so as to be in any state, and the same operation is uniformly applied to the drive means (42) of each seat (1). seat control device according to [1] or [2], wherein the instructing (100).

[ 4 ] The multiple seats (1) are grouped, and each grouped seat group is ordered,
The control means (110) sequentially converts each seat (1) to be in any state for each group sequentially from the upper seat group, and drives each seat (1) for each group The seat control apparatus (100) according to [ 3 ], wherein the same operation is uniformly instructed to the means (42).

[ 5 ] The plurality of seats (1) are arranged side by side, and are divided into two groups from the top row into the odd row seats (1) and the even row seats (1). The seat control device (100) according to the above [ 4 ].

[ 6 ] The first state of the seat (1) is a long state in which the seat is laterally oriented with respect to the front-rear direction,
The second state of the seat (1) is one cross state which is forward with respect to the front-rear direction,
A third state of the seat (1), the which is a reverse cross state as a rearward with respect to the longitudinal direction [1], [2], [3], [4] or [ The seat control apparatus (100) as described in 5 ].

[ 7 ] The conversion mechanism (10) of the seat (1) is a rotation mechanism (40) rotatably supporting the seat (1), and the seat (1) along the rotation mechanism (40) in the left-right direction A slide mechanism (14) for movably supporting, rotation of the seat (1) by the rotation mechanism (40) and the slide mechanism (14) when converting the seat (1) to the long state or the one-cross state. And an interlocking mechanism (50) for interlocking movement of the seat (1) according to the seat control device (100) according to the above-mentioned [ 6 ].

Next, the operation based on the above-described solution will be described.
According to the seat control device (100) described in the above [1], the seat (1) is at least given three predetermined states by the conversion mechanism (10): the first state, the second state, and the second state It can be converted to 3 states. Here, the state of the seat (1) means various states including the orientation and posture of the seat (1), and the seat (1) is not limited to the orientation of the seat (1) by the horizontal rotation of the entire seat. The inclination angle of the seat or the posture of the seat is also included.

  The first state or the second state of the seat (1) can be converted directly from both sides, and the second state to the third state of the seat (1) can also be converted directly from both sides it can. However, the first state to the third state of the seat (1) can not be converted directly, but can be converted from both sides through the second state between them. Thus, the second state of the seat (1) is in the middle of these conversion processes between the first state and the third state of the seat (1).

  The conversion mechanism (10) of the seat (1) is driven by the drive means (42), and the operation of the drive means (42) is controlled by the control means (110). Therefore, although the drive means (42) operates electrically, the conversion mechanism (10) is not necessarily driven by the electric drive of the drive means (42), and is manually driven by an operator (for example, a passenger) manually. It may be configured to be able to In this case, the state of the seat (1) is not limited to the state controlled by the control means (110), and may be a state arbitrarily operated by the operator.

  In any case, the control means (110) can automatically convert the seat (1) into the first state, the second state, and the third state by controlling the operation of the drive means (42). it can. In such control, it is troublesome to determine the state of the seat (1) before conversion one by one, and the flow of control for converting each state is simplified as follows.

  That is, when the seat (1) is to be converted to the first state, the control means (110) instructs the drive means (42) to perform the operation to convert the third to the second state first, and then An operation to convert from 2 to the first state is instructed. According to such a two-step instruction, even if the seat (1) is in any of the first to third states, the seat (1) can be uniformly converted to the first state.

  When the seat (1) is to be converted to the second state, the control means (110) instructs the drive means (42) to perform an operation to convert the first to the second state. Command the operation to be converted to the second state. There is no temporal relationship between the two instructions here, and the two instructions allow the seat (1) to be uniformly selected as the second regardless of whether the seat (1) is in the first or third state. It can be converted to a state.

When the seat (1) is to be converted to the third state, the control means (110) instructs the drive means (42) to perform the operation to convert the first to the second state, and then An operation to convert from 2 to a third state is instructed. By such a two-step instruction, even if the seat (1) is in any of the first to third states, the seat (1) can be uniformly converted to the third state.
It is possible to convert the seat (1) into an arbitrary state regardless of the state of the seat (1) with only the above-mentioned minimum command.

Further, the seat control device (100), among the three states of the seat (1), detects that the probability of the most position (via) has a seat in the high second state (1) detection means (18) Equipped with And, when the control means (110) converts the seat (1) from the first state or the third state to the second state, the detection means that the seat (1) is already in the second state When (18) is detected, the operation of converting to the second state is not performed.

  Thereby, in the conversion of the seat (1), it is possible to eliminate unnecessary driving of the drive means (42) most frequently. Note that, as a specific control, the operation of the conversion may not be performed by canceling the instruction of the operation of converting to the second state. Alternatively, although the command of the operation for converting to the second state is output, the control may be controlled to stop the operation of the conversion based on another command regardless of the output.

According to the seat control device (100) described in the above [ 2 ], the control means (110) instructs the seat (1) to move from one of the states to the other state. If 1) is under the predetermined condition, the motor (42) is uniformly rotated. Thus, the control flow for selectively operating the motor (42) can be eliminated as much as possible, and the control can be simplified.

  Further, the blocking of the conversion of the seat (1) under predetermined conditions which is not originally supposed can be simply blocked mechanically by the stoppers (16, 17) without undergoing a complicated control flow. Here, since the motor (42) can be put on hold, there is no risk of breakage due to overload.

The control of the operation for converting the state of the seat (1) can be executed not only for one seat (1) but also for a plurality of seats (1) as described in [ 3 ]. When targeting a plurality of seats (1), the conversion mechanism (10) and the drive means (42) are provided for each seat (1) as a premise. Then, the control means (110) simultaneously converts each seat (1) into any state, and the same applies to the drive means (42) of each seat (1). Instruct the operation.

  According to such control, when converting the state of each seat (1), it is not necessary to determine the state before each conversion. That is, even if each seat (1) is in any state, the same command is uniformly output to the drive means (42) of each seat (1), and the same operation is simultaneously performed to the conversion mechanism (10) By making it possible, it is possible to make conversion quickly so as to be in a specific state.

Further, as described in [ 4 ], a plurality of seats (1) may be divided into groups, and a series of control may be performed for each of the divided seat groups. Here, each seat group is ordered, and the control means (110) converts all the seats (1) at the same time in each group in order from the upper seat group sequentially. That is, the control means (110) instructs the drive means (42) of each seat (1) uniformly the same operation for each group.

As a specific grouping, for example, as described in the above [ 5 ], when a plurality of seats (1) are arranged side by side, the seats (1) in odd-numbered rows are arranged in order from the top row It is good to divide it into two with the even row seat (1). Here, the ordering of the two groups may be either higher, and upon conversion of the state of each seat (1), adjacent seats (1) adjacent to each other do not operate at the same time, but every other one Since the seats (1) of (1) operate at the same time, interference between the seats (1) in operation can be prevented.

Also, with regard to the state of the seat (1), for example, as described in [ 6 ] above, the first state is a long state in which the sideways to the front-back direction is made, and the second state is in the front-back direction The third state may be a reverse cross state in which the second state is backward with respect to the front-rear direction. Thereby, it can apply as it is to the general seat (1) mounted in a rail car.

Furthermore, as the conversion mechanism (10) of the seat (1), for example, as described in [ 7 ], a rotation mechanism (40) rotatably supporting the seat (1) and a rotation of the seat (1) The slide mechanism (14) which supports the mechanism (40) so as to be movable in the lateral direction, and the seat (1) is rotated by the rotation mechanism (40) when the seat (1) is converted to the long state or the one cross state. And an interlock mechanism (50) for interlocking movement of the seat (1) by the slide mechanism (14). According to the conversion mechanism (10), even if the seat (1) is disposed close to the wall surface, interference with the wall surface can be prevented during operation of the seat (1).

  According to the seat control device according to the present invention, the control for converting the state of the seat is simplified, and a plurality of seats can be converted simultaneously at once, and the conversion operation is easily controlled by the simple program and parts. And cost can be reduced.

Hereinafter, an embodiment representing the present invention will be described based on the drawings.
1 to 33 show an embodiment of the present invention.
The seat control device 100 according to the present embodiment controls an operation of converting the state of the seat 1. As shown in FIG. 1, the seat control apparatus 100 includes a motor (driving means) 42 for driving the conversion mechanism 10 capable of converting the state of the seat 1, and a control means 110 for controlling the operation of the motor 42. There is.

First, the seat 1 to be controlled will be described.
Although the type of the seat 1 is not particularly limited, a case where the seat 1 is applied to a seat for two persons mounted in a passenger compartment of a railway vehicle will be described as an example below. As shown in FIG. 3, in the passenger compartment A of the railcar, a plurality of seats 1 are arranged side by side in a row on both sides in the front-rear (advancing) direction, and a passage is formed between both rows. The seat 1 has two seats and backrests arranged side by side, for example, for a double seat.

  Each seat 1 is provided with a conversion mechanism 10 capable of converting the state of the seat 1 into a first state, a second state, and a third state, as predetermined three states. Here, the state of the seat 1 refers to various states including the orientation and posture of the seat 1 and is not limited to the direction of the seat 1 by the horizontal rotation of the entire seat 1, and the backrest or seat portion of the seat 1 Although the tilt angle, the posture, and the like are included, in the present embodiment, the “direction” of the seat 1 is set as the state.

  In the first state (hereinafter, the long position) in which the seat 1 is horizontal to the front-rear direction and the seat back side is parallel to the wall surface A1 by the conversion mechanism 10, the seat 1 is in the front-rear direction The second state in which the seat back side is orthogonal to the wall surface A1 (hereinafter referred to as one cross state), and the third state in which the seat 1 is backward with respect to the front and rear direction and the seat back side is orthogonal to the wall surface A1. Each can be converted to (in the reverse cross state).

  Assuming that the angle of the long state of the seat 1 is 0 °, turning 90 ° in one direction to 90 ° results in one cross state (90 °), and rotating 180 ° in one direction to the reverse cross state (270 °) Become. Although the details will be described later, the seat 1 can also rotate in the reverse direction. However, the rotation in one direction from the reverse cross state is restricted, and the rotation in the reverse direction from the long state is also restricted.

  The long state or one cross state of the seat 1 can be converted directly from both sides, and the one cross state or the reverse cross state of the seat 1 can also be converted directly from both sides. However, the long state or reverse cross state of the seat 1 can not be converted directly, but can be converted from both by passing through one cross state between them. Thus, one cross state of the seat 1 is in the middle of the conversion process between the long state and the reverse cross state of the seat 1.

  As shown in FIG. 8, the conversion mechanism 10 includes, as part of the configuration of each seat 1, a footrest 11, a movable stand 20, and a frame 30 of the seat 1. In addition, the conversion mechanism 10 includes a rotation mechanism 40 rotatably supporting the seat 1, a slide mechanism 14 supporting the seat 1 movably in the left-right direction together with the rotation mechanism 40, and a long state or one cross state The interlock mechanism 50 interlocks the rotation of the seat 1 by the rotation mechanism 40 and the movement of the seat 1 by the slide mechanism 14 at the time of conversion.

  9 shows the conversion mechanism 10 in the long state, FIG. 10 shows the conversion mechanism 10 in the one cross state, and FIG. 11 shows the conversion mechanism 10 in the reverse cross state. Hereinafter, when the one cross state and the reverse cross state are collectively referred to, they are simply referred to as the cross state. FIG. 12 shows a long state of the conversion mechanism 10 with the underframe 30 removed, and FIG. 13 shows a cross state of the conversion mechanism 10 with the underframe 30 removed.

  As shown in FIGS. 12 and 13, the footrest 11 is fixed on the floor surface beside the wall surface A1 (see FIG. 8) in the vehicle cabin. The footrest 11 is configured by combining frame members in the shape of a long gantry in a direction substantially orthogonal to the wall surface A1. The upper surface 12 covering the upper side of the footrest 11 is substantially horizontal, and the long sides on both sides extending in the longitudinal direction of the upper surface 12 are substantially orthogonal to the wall surface A1, and the front and rear short sides of the upper surface 12 are the wall surface A1 It is arranged substantially parallel.

  The upper surface portion 12 is provided with an avoidance portion 12a through which a rotation shaft 41 moving along with the movement of the movable table 20 described later can pass along the movement trajectory. The avoidance portion 12 a is provided as a bay-like notch that opens toward the front short side from the short side on the front side of the top face 12 to the approximate center and is recessed inward. The avoidance portion 12 a is a portion for preventing the rotation shaft 41 from interfering with the upper surface portion 12. In addition, related components such as a stopper 16 for restricting the rotational direction of the underframe 30 are also mounted on the upper surface portion 12.

  Just below the upper surface portion 12 of the footrest 11, the movable table 20 is attached via the slide mechanism 14 so as to be movable back and forth in a direction (left and right direction) orthogonal to the wall surface A1. The slide mechanism 14 includes a pair of guide rails 15 and 15 provided on the inner side of the side portions 13 and 13 of the footrest 11. The pair of guide rails 15, 15 oppose each other in parallel along both long sides of the upper surface portion 12 of the footrest 11, and on the inner side of each guide rail 15, both side portions 21, 21, 21 is slidably fitted as it is.

  The movable table 20 is disposed below the upper surface portion 12 of the footrest 11, and is configured by combining frame members in a rectangular frame shape. Both side portions 21 of the movable table 20 are slidably fitted to the inside of the aforementioned guide rail 15. Therefore, the movable table 20 is slidable so as to advance or retract in a direction substantially orthogonal to the wall surface A1.

  A mounting portion 22 of a rotation mechanism 40 (see FIG. 8) for rotatably supporting the seat 1 is provided substantially at the center of the moving table 20. Underframe 30 is rotatably supported on movable table 20 by rotation mechanism 40 attached to attachment portion 22. For example, although not shown, the rotation mechanism 40 is configured as a unit in which a pair of upper and lower ring-shaped rotary discs are rotatably combined with each other with a bearing or the like interposed therebetween. In the rotation mechanism 40, the lower rotary disc is fixed around the circular hole in the mounting portion 22, and the upper rotary disc is fixed on the bottom side of the underframe 30.

  The conversion mechanism 10 is provided with a motor 42 as driving means for driving the rotation mechanism 40 first. A motor (not shown) is provided with a speed reducer and is configured to be able to be hit and stopped. For example, a torque motor having a resistance to an output torque equal to or more than a predetermined value at the time of hit and hold is suitable. A sprocket that rotates integrally with the output shaft is supported on the output shaft of the motor 42, and the teeth on the outer periphery of the sprocket are partially protruded above the upper surface 12 by the avoidance portion 12a of the footrest 11. ing.

  The rotation axis 41 of the rotation mechanism 40 serving as the rotation center of the seat 1 is the center line of the upper and lower rotary disks, and in the present embodiment, it does not have a physical reality. It extends upward from the lower side, and does not interfere with the upper surface 12 by passing through the avoidance portion 12a. As described above, the underframe 30 is integrally attached to the upper rotary disc around the rotating shaft 41, and the seat 1 and the underframe 30 rotate around the rotating shaft 41.

  As shown in FIGS. 9 to 11, the underframe 30 is disposed on the upper side of the upper surface portion 12 of the footrest 11 and is formed of a rectangular metal plate. The underframe 30 is for mounting and supporting the seat 1 and has a rectangular shape that is long in both directions that matches the bottom of the seat 1. Although not shown, a plurality of perforations in which the teeth of the sprockets mesh with each other are arranged in a row on the underframe 30 along the circumference centered on the rotation shaft 41.

  Therefore, when the sprocket is rotated by the motor 42, the plurality of perforations arranged on the circumference of the underframe 30 around the rotation shaft 41 sequentially rotate, so that the seat 1 is rotated by the power of the motor 42. It is configured. Specifically, the conversion from the long state of the seat 1 to the one cross state and the conversion from the one cross state to the reverse cross state are performed by the forward rotation of the motor 42. On the other hand, the conversion from the reverse cross state to the one cross state and the conversion from the one cross state to the long state of the seat 1 are set to be performed by the reverse rotation of the motor 42.

  However, as shown in FIG. 1, the right-handed seat 1 and the left-handed seat 1 are arranged so as to be mutually symmetrical with respect to each other, with the central passage of the passenger compartment A of the railway vehicle It is done. Therefore, although the right row seat 1 and the left row seat 1 rotate or slide symmetrically, respectively, the rotation direction of the motor 42 is reversed or the rotation direction of the motor 42 is unified accordingly. You may configure it.

  As shown in FIG. 20, on the underframe 30, there is provided a stopper 16 for blocking conversion of the seat 1 from the reverse cross state to the one cross state by forward rotation of the motor 42. The stopper 16 is a member for restricting the seat 1 not to rotate by 270 ° or more by engaging with the engaged portion (not shown) provided on the bottom surface side of the seat 1.

  As shown in FIG. 14, a stopper 17 is provided on the underframe 30 for blocking conversion of the seat 1 from the long state to the one-cross state by the reverse rotation of the motor 42. The stopper 17 is a member for restricting the seat 1 not to rotate below 0 ° by engaging with an engaged portion (not shown) provided on the bottom side of the seat 1.

  The conversion mechanism 10 also includes an interlocking mechanism 50 that interlocks rotation and forward / backward movement of the seat 1 so that the seat 1 does not interfere with the wall surface A1 when the direction of the seat 1 is converted to a long state or a cross state. When the seat 1 is rotated together with the underframe 30, the interlocking mechanism 50 converts the rotation of the underframe 30 into a linear motion and transmits it to the moving table 20 through the rotating mechanism 40, and the moving table 20 is transferred to the underframe 30. And move forward and backward in a direction perpendicular to the wall surface A1.

  As shown in FIGS. 9 and 10, the interlocking mechanism 50 includes a guide rail 51 provided on the upper side of the upper surface portion 12 of the leg 11, and a roller 52 provided on the lower side of the pedestal 30. . Further, the roller 52 is provided with an auxiliary roller 53. The guide rail 51 is formed in an elongated shape extending on both sides of the mounting portion 22 while bending in both directions on the upper surface portion 12 of the footrest 11, and has a predetermined height above the horizontal reference surface of the upper surface portion 12. Projected into

  The roller 52 is rotatably supported at the lower side of the underframe 30 so as to protrude downward at a position eccentric from the rotation shaft 41 of the seat 1. As shown in FIG. 22, the base end of the arm 54 is pivotally supported by the rotation shaft 52a of the roller 52, and the tip end of the arm 54 is capable of rotating the auxiliary roller 53 and around the rotation shaft 52a. It is pivotally supported for revolution. The auxiliary roller 53 is movable along the arc-shaped guide groove 55 centered on the rotation shaft 52 a in the underframe 30, and is supported so as to be close to or separated from the roller 52, and the spring member 56. It is always biased in the approaching direction via.

  The roller 52 and the auxiliary roller 53 hold the guide rail 51 from both sides when the seat 1 is converted to the long state or the cross state. In this state, the roller 52 and the auxiliary roller 53 move from one end of the guide rail 51 to the other end as the seat 1 rotates, and the rotation of the underframe 30 is converted into a linear motion. Transmitted to Thus, the seat 1 can be converted from the long state of FIG. 9 to the one cross state of FIG. 10, and conversely, from the one cross state to the long state.

  Moreover, the conversion mechanism 10 is provided with the rotation lock mechanism 60 which restrains the underframe 30 (seat 1) non-rotatably in each rotation position of a long state and a cross state. Here, since the rotation lock mechanism 60 restrains the underframe 30 so as not to rotate with respect to the footrest 11, the movable stand 20 is inevitably restrained from moving back and forth relative to the footrest 11.

  As shown in FIGS. 9 to 11, the rotation lock mechanism 60 is provided on the underframe 30 with a lock pin 61 that can be vertically extended and retracted from the leg 11 side to the underframe 30, and the lock pin 61 is engaged and disengaged And locking holes 62a, 62b, and 62c. Each of the locking holes 62a, 62b and 62c is provided in total on the long side of the rectangular underframe 30 along the back side of the seat and on both short sides along the both sides of the seat 1. . Each locking hole 62a, 62b, 62c is not a partially open notch at a position slightly away from the edge of each side of the underframe 30, and the circumference is surrounded to improve strength by avoiding stress concentration. It is provided as a hole.

  The lock pin 61 is incorporated into the unit 60 a, and the unit 60 a is attached to the lower side of the upper surface portion 12 of the footrest 11. A hole through which the lock pin 61 is inserted is formed in the upper surface portion 12, and the lock pin 61 can be projected and retracted above the upper surface portion 12 of the footrest 11. When the seat 1 is converted to the long state or the cross state, the lock pin 61 is inserted into and engaged with the locking holes 62a, 62b, 62c on the underframe 30 side which vertically match at the position.

  Specifically, in the long state shown in FIG. 9, the lock pin 61 is inserted into and engaged with the locking hole 62 a on one long side of the underframe 30. Further, in the one-cross state shown in FIG. 10, the lock pin 61 is inserted into and engaged with the locking hole 62b on the short side of the underframe 30. Further, in the reverse cross state shown in FIG. 11, the lock pin 61 is inserted into and engaged with the locking hole 62c on the other short side of the underframe 30. At a position where the lock pin 61 protrudes downward from the upper surface portion 12, a part of the movable table 20 advancing and retracting below the upper surface portion 12 does not interfere.

  The lock pin 61 moves up and down by electric operation and manual operation and protrudes upward and is inserted into the locking holes 62a, 62b and 62c, and is recessed downward and disengaged from the locking holes 62a, 62b and 62c. Displace to the release position. Here, the stroke from the lock position of the lock pin 61 to the release position has a difference between the electric operation and the manual operation. More specifically, as shown in FIG. 23, the lock pin 61 is incorporated in the unit 60a so as to move up and down via a drive mechanism including a link 63 whose one end is the rotation center 63a.

  Here, the motor-side cable 64 and the manual-side cable 65 for driving the link 63 are connected to portions of the link 63 which have different rotation radii. When the operation amount of each of the cables 64 and 65 is the same, the stroke of the cable closer to the rotation center 63 a of the link 63 is larger. The stroke of the lock pin 61 by the manual side cable 65 is set to half of that in the case of the motor side cable 64 by utilizing the difference of the rotation radius.

  Further, the manual side cable 65 is connected with a manual lever which is not shown in the figure, and has a function of adjusting the stroke also in the manual lever. Therefore, the motor-side cable 64 and the manual-side cable 65 can be attached reversely, and the stroke diameter of the lock pin 61 by the operation of the manual-side cable 65 can be shortened without using the difference in the turning radius.

  On the other hand, with regard to the locking holes 62a, 62b and 62c in which the lock pin 61 is engaged and disengaged, the locking holes 62a for locking (restraining) the seat 1 in the long state as shown in FIGS. On the lower side, a metal plate 32 having a hole that matches the locking hole 62a is attached. Therefore, with regard to the locking hole 62a, the lock can not be released unless the lock pin 61 is made to make a stroke larger by the thickness of the sheet metal 32 than the other locking holes 62b and 62c (see FIG. 24B). It is set.

  The point is that when the seat 1 is in the long state, the lock of the rotation lock mechanism 60 can not be released by the operation by the manual cable 65, and can be released by the operation by the electric cable 64. The electric operation is performed by the crew or station staff of the vehicle, and the manual operation is mainly performed by the passengers.

  In addition, an emergency manual operation unit connected to each of the rotation lock mechanism 60 and the forward / backward lock mechanism 70 is separately provided on the leg or the like of the footrest 11 so that the lock can be released in an emergency such as a power failure. The stroke amount of the lock pins 61 and 71 by the operation of the manual operation section for emergency is larger than the thickness of the sheet metal 32 and the hinge 75, respectively, so that it is possible to convert from long state to cross state or cross state to long state in emergency. is there.

  According to such a rotation lock mechanism 60, the lock pin 61 protrudes and retracts from the footrest 11 fixed to the vehicle. Therefore, when the underframe 30 is locked in a non-rotatable manner, the moving stand 20 on which the underframe 30 is supported via the rotation mechanism 40 is also locked so as not to move back and forth simultaneously. The non-rotatable and non-rotatable simultaneous locks of the seat 1 attach the lock pin 61 not to the movable table 20 but to the footrest 11 and avoid the interference with the rotation mechanism 40 on the upper surface 12 of the footrest 11. It is realized by opening 12a.

  Furthermore, the conversion mechanism 10 is provided with an advancing / retracting locking mechanism 70 for restraining the underframe 30 (seat 1) in an unremovable manner in the positions of the long state and the cross state. The forward / backward locking mechanism 70 is configured to restrain the movable table 20 relative to the footrest 11 so as not to be able to forward or backward, separately from the rotation locking mechanism 60. According to the forward / backward locking mechanism 70, even in the state where the restraint by the rotary locking mechanism 60 is released, only forward / backward movement of the seat 1 can be restricted.

  As shown in FIG. 25, the forward / backward locking mechanism 70 is provided on the movable table 20 with a lock pin 71 capable of moving up and down over the movable table 20 from the footrest 11 side, and a lock for engaging and disengaging the lock pin 71. And holes 72a and 72b. As shown in FIG. 18, a total of two locking holes 72 a and 72 b are respectively provided at the front and rear ends of the frame member 23 extending in the front and rear direction on the rear lower side of the movable table 20. Each locking hole 72a, 72b is not a notch that is partially open at the front and rear ends of the frame member 23, but is provided as a hole whose circumference is surrounded to improve strength by avoiding stress concentration.

  The lock pin 71 is incorporated into the unit 70 a, and the unit 70 a is disposed inside the footrest 11 located below the movable table 20. When the seat 1 is converted to a long state or a cross state, the lock pins 71 project upward and downward from immediately below the frame member 23 of the movable table 20, and the locking holes 72a are aligned with the upper and lower positions at that position. It inserts in 72b and engages. The lock pin 71 is attached to the side of the foot 11 in the same manner as the lock pin 61, but the attachment position is different.

  Specifically, in the long state shown in FIG. 15, the lock pin 71 is inserted into and engaged with the front locking hole 72a (see FIG. 25). However, the lock pin 71 in the long state need not necessarily be inserted into the locking hole 72a. Further, in the one-cross state shown in FIG. 18, the lock pin 71 is inserted into and engaged with the rear locking hole 72b (see FIG. 25). Similarly, also in the reverse cross state shown in FIG. 21, the lock pin 71 is inserted into and engaged with the rear locking hole 72b.

  As shown in FIG. 27, the lock pin 71 is always biased by the spring member 73 to the lock position projecting upward. The lock pin 71 is displaced to the release position where it is sunk downward against the biasing force of the spring member 73 only by the electric operation. The lower end of the lock pin 71 is connected to a solenoid (not shown) via a link 74. By driving the solenoid, the lock pin 71 is pulled downward and displaced to the release position. Therefore, unlike the case of the lock pin 61 of the rotation lock mechanism 60, the lock pin 71 operates only by the electric operation, and the lock can not be released by the manual operation.

  According to the forward / backward locking mechanism 70, when it is locked by the rotary lock mechanism 60, there is no need to operate, but when the rotary lock mechanism 60 is unlocked, the movable base 20 is underframe 30 (seat 1) It can be locked in a non-removable manner. That is, when the seat 1 can not be rotated, the seat 1 can not be advanced or retracted, but when the seat 1 can be rotated, only the seat 1 can be advanced or retracted, or can be advanced or retracted with the rotation of the seat 1 .

  When the seat 1 is rotated 90 ° from the long state (0 °) to the one cross state (90 °) in the forward / backward locking mechanism 70, the tip of the lock pin 71 is the front end side of the frame member 23 shown in FIG. It moves relative to the rear end side (left side in the drawing) from the right side in the drawing through the locking hole 72b, and slightly returns to the front end side and is inserted into the locking hole 72b (see FIG. 19). ). Here, when the lock pin 71 moves to the rear end side, it is necessary not to enter the locking hole 72b by the biasing force of the spring member 73.

  Therefore, as shown in FIG. 25, a hinge 75 for temporarily closing the locking hole 72b is provided on the front side of the locking hole 72b so as to be capable of raising and lowering. The hinge 75 is normally urged in a standing state before the locking hole 72b. As shown in FIG. 26, when the tip of the lock pin 71 relatively moved from the front hits, the hinge 75 is provided to be closed in a state of closing the locking hole 72b against the biasing force. The hinge 75 does not fall in the opposite direction.

  Conversely, when the front end of the lock pin 71 moves relatively forward from the rear end side to the front end side of the frame member 23, the lock pin 71 enters into the locking hole 72 b or is caught by the hinge 75 which stands up. It is necessary not to. Therefore, as shown in FIG. 27, a side pin 76 for holding the lock pin 71 in a retracted state against the biasing force of the spring member 73 is provided beside the lock pin 71.

  The side pin 76 is detachably supported on the lock pin 71 from the side orthogonal to the axial direction of the lock pin 71. Locking holes 71a and 71b are formed on the outer periphery of the lock pin 71 at positions separated vertically. When the tip of the side pin 76 engages with the upper locking hole 71a of the lock pin 71 as shown in FIG. 28, the lock pin 71 is held in the retracted release position, and as shown in FIG. It can move without being caught. When the tip of the side pin 76 engages with the lower locking hole 71b of the lock pin 71, the lock pin 71 is held in the protruding lock position.

  As shown in FIGS. 30 and 31, the side pin 76 is axially moved in a state in which the tip is engaged with the locking holes 71a and 71b of the lock pin 71 via the swinging member 77 and in a state in which the side pin 76 is disengaged. It is movably supported. The tip end of the swinging member 77 is pushably connected in the middle of the side pin 76, and the base end on the opposite side of the tip and the swing center is connected to the release lever 78 fixed on the movable table 20 side. It is arranged to be disengaged. Therefore, when the release lever 78 is engaged with the base end of the swinging member 77 and pushed, the side pin 76 is separated from the lock pin 71 as the tip of the swinging member 77 swings, and the lock by the side pin 76 Restraint of the pin 71 is released.

Next, the seat control apparatus 100 which is the basis of the present invention will be described.
As shown in FIG. 1, the seat control device 100 detects the motor (drive means) 42 for driving the conversion mechanism 10 capable of converting the state of the seat 1 and a sensor for detecting that the seat 1 is in one cross state ( A detection means 18, an operation switch 101 for performing various operations, and a control panel (control means) 110 for controlling the operation of the motor 42 are provided.

  The control panel 110 comprehensively monitors and controls the operation of the motor 42 and the transmission and reception of signals of the sensor 18 and the like, and functions as the “control means” in the present invention. The control panel 110 is composed of a CPU that performs various data processing, a ROM that is a main memory, a RAM, and a sequencer that mainly includes an input / output circuit, a communication circuit, and the like.

  The control panel 110 is usually installed at a driver's seat or the like, and centrally controls conversion of a plurality of seats 1 in the cabin A. Although FIGS. 2 to 6 show the control of each seat 1 of only the cabin A of one vehicle by the control panel 110, all the seats 1 in the cabin A of all the vehicles can be controlled by one control panel 110. It can also be configured.

  The motor 42 and sensor 18 of each seat 1 are connected to the control panel 110 via a relay (not shown) installed for each seat 1. In practice, the seats R1 to R4 in the right row and the seats L1 to L4 in the left row shown in FIG. 2 may be separately connected to the control panel 110 via separate repeaters. The motor 42 can be fixed as described above, and for example, a torque motor is suitable.

  Although not shown, the sensor 18 is attached to the upper surface 12 of the footrest 11 and corresponds to a "detection means" which turns on when the underframe 30 (seat 1) is in a cross state and outputs a detection signal. It is a thing. The sensor 43 is configured of, for example, a proximity switch or a magnetic sensor that operates according to the distance to a part of the frame 30, and is connected to the control panel 110 via the relay.

  In addition, the operation switch 101 is normally installed in the driver's seat or the like like the control panel 110, and an instruction to convert each seat 1 to a long state, an instruction to convert each seat 1 to a cross state, and A button or the like for performing an input operation of an instruction to convert the seat 1 into the reverse cross state is provided. The operation switch 101 is connected to the control board 110 via a signal line.

As shown in FIG. 2, the conversion of each seat 1 is programmed as follows as a function that the control panel 110 performs.
a. When the control panel 110 converts the seat 1 to the long state, an operation of first converting the reverse cross state to the one cross state to the motor 42 of each seat 1 based on the instruction from the operation switch 101 (reverse of the motor 42 The rotation (180 °) is instructed, and then an operation (reverse rotation 90 ° of the motor 42) to convert from one cross state to a long state is instructed.

b. When the control panel 110 converts the seat 1 to the one cross state, an operation to convert the motor 42 of each seat 1 from the long state to the one cross state based on an instruction from the operation switch 101 (forward rotation of the motor 42 (90.degree.) And an operation (reverse rotation 180.degree. Of the motor 42) for converting the reverse cross state into one cross state. There is no temporal relationship between the two operation commands here, and either one may be output first.

c. When the control panel 110 converts the seat 1 into the reverse cross state, an operation of first converting the motor 42 of each seat 1 from the long state to the one cross state based on an instruction from the operation switch 101 An instruction (rotation 90 °) is given, and then an operation (forward rotation 180 ° of the motor 42) to convert from one cross state to the reverse cross state is instructed.

  The command to convert the seat 1 from the long state to the one cross state and the command to convert the one cross state to the reverse cross state are common as an operation command signal to rotate the motor 42 in a forward direction. The time is different. Further, the command to convert each seat 1 from the reverse cross state to the one cross state and the command to convert the one cross state to the long state are common as an operation command signal to reversely rotate the motor 42. Operating time) is different.

  Further, when the control panel 110 converts each seat 1 from the long state or the reverse cross state to the one cross state, when the sensor 18 detects that the seat 1 is already in the one cross state, one cross at that time is detected. There is no action to convert to state. Such control may stop the conversion operation by stopping the operation of converting into one cross state (forward rotation 90 ° or reverse rotation 180 ° of the motor 42). Alternatively, although the command of the operation for converting into the one cross state is output, the control may be controlled to stop the operation based on another command regardless of the output.

  In addition, when the control panel 110 instructs an operation to convert each seat 1 from any one state to another state, the motor 42 is uniformly rotated even when the seat 1 is under a predetermined condition. It is set. However, even if the motor 42 rotates when the seat 1 is under a predetermined condition, the conversion of the seat 1 due to the rotation of the motor 42 is blocked by the stoppers 16 and 17.

  Here, the predetermined condition is that the seat 1 is in the reverse cross state when an operation to convert the seat 1 from the long state to the one cross state and an operation to convert the one cross state to the reverse cross state are instructed. It is. Also in this case, the control panel 110 causes the motor 42 to rotate forward uniformly, but the stopper 16 prevents conversion of the seat 1 from the reverse cross state to the one-cross state due to the forward rotation of the motor 42.

  Similarly, when the operation to convert the seat 1 from the reverse cross state to the one cross state and the operation to convert the one cross state to the long state are instructed, the predetermined condition is also satisfied when the seat 1 is in the long state. The control panel 110 reversely rotates the motor 42 uniformly, but the stopper 17 prevents conversion of the seat 1 from the long state to the one-cross state due to the reverse rotation of the motor 42.

  Furthermore, according to the control panel 110, each seat 1 can be grouped, and the grouped seat groups are ordered. The control panel 110 is to convert all the seats 1 in each group at the same time to any state in order from the upper group, and the same is uniformly applied to the motor 42 of each seat 1 in each group. The operation (control of the above a to c) is instructed. In the present embodiment, the passenger compartment A of the railcar shown in FIG. 3 is divided into two groups, the seat 1 in the odd-numbered row and the seat 1 in the even-numbered row sequentially from the top.

Next, details of the operation of the conversion mechanism 10 according to the present embodiment will be described.
As shown in FIG. 8, in the conversion mechanism 10, the movable table 20 is disposed on the lower side with the upper surface 12 of the footrest 11 in between, and supported on the upper side by the rotational mechanism 40 on the movable table 20. An underframe 30 is arranged. Therefore, the conversion mechanism 10 has a structure in which the footrest 11, the movable stand 20, the upper surface portion 12 of the footrest 11, and the underframe 30 sequentially overlap from the bottom.

  In the case of such a structure, the upper surface portion 12 interposed between the moving table 20 and the underframe 30 as it is would interfere with the movement of the rotary shaft 41 when the moving table 20 advances and retracts. Since it passes through the avoidance portion 12a, it does not interfere with the upper surface portion 12. Thereby, advancing and retreating of the movable stand 20 under the upper surface portion 12 of the footrest 11 can be realized.

  As shown in FIG. 33, when the seat 1 is rotated together with the frame 30, the rotation of the frame 30 is converted into linear motion and transmitted to the movable table 20 via the rotation mechanism 40. Therefore, the movable stand 20 advances and retreats in the direction orthogonal to the wall surface A1 (see FIG. 8) together with the rotating underframe 30. A long state in which the seat back side is parallel to the wall surface A1 so that the seat 1 does not interfere with the wall surface A1 even if the seat 1 approaches the wall surface A1 by the interlock of rotation and advancing and retreating of such a seat 1 (FIG. 33 (a)) The orientation of the seat 1 can be easily converted by a series of operations into a cross state in which the seat back side is orthogonal to the wall surface A1 (FIG. 33 (c)).

  As shown in FIGS. 9 and 14, when the underframe 30 of the seat 1 is in the long state (0 °), the lock pin 61 of the rotation lock mechanism 60 is a locking hole 62 a on one long side of the underframe 30. Inserted into and engaged. Here, since the lock pin 61 protrudes and retracts from the footrest 11 fixed on the floor surface, the seat 1 is locked not only in a non-rotatable manner but also in an advancing and retracting manner. At this time, there is no need to lock the lock mechanism 70 in particular, and the lock pin 71 is in a free state.

  As shown in FIGS. 33 (a) to 33 (c), in order to convert the underframe 30 (seat 1) from the long state (0 °) to one cross state (90 °), the motor 42 rotates forward. It is performed only by the electric operation. In order to remove the lock pin 61 of the rotation lock mechanism 60 from the locking hole 62a, it is necessary to make an extra stroke by the thickness of the sheet metal 32 shown in FIG. 24 (a). It becomes possible. Therefore, when the seat 1 is in the long state (0 °), the lock of the rotation lock mechanism 60 can not be released by the manual operation.

  In FIG. 33 (a), after unlocking the rotation lock mechanism 60 by electric operation, as shown in FIG. 33 (b), the underframe 30 (seat 1) is turned to one direction (clockwise in FIG. 33). When rotated, the frame 30 rotates while being converted into linear motion by the interlocking mechanism 50. That is, underframe 30 rotates forward while largely rotating to the passage side so as not to interfere with wall surface A1 (refer to FIG. 8) at the time of rotation of underframe 30, and then 90 ° while slightly retracting to be drawn into wall surface A1. Rotate.

  As shown in FIGS. 14 and 17, in the interlocking mechanism 50, the roller 52 on the underframe 30 side and the auxiliary roller 53 sandwich the guide rail 51 on the leg 11 side from both sides. In this state, the roller 52 and the auxiliary roller 53 move from one end of the guide rail 51 to the other end as the frame 30 rotates, and the rotation of the frame 30 is converted into linear motion. Here, the roller 52 moves while rotating along one side surface of the guide rail 51, and the auxiliary roller 53 also eccentrically rotates while being pressed along the other side surface of the guide rail 51, the respective rollers 52, 53 It does not come off the guide rail 51.

  As shown in FIG. 33 (c), when the underframe 30 (seat 1) reaches one cross state (90 °), the lock pin 61 of the rotation lock mechanism 60 is locked on the short side of the underframe 30. When inserted into and engaged with the hole 62b (see FIG. 17), the underframe 30 is locked non-rotatably. At the same time, the lock pin 71 of the forward / backward locking mechanism 70 moves to a position where it can be inserted into the rear locking hole 72b (see FIG. 19) of the movable table 20.

  Here, the tip end of the lock pin 71 passes over the locking hole 72b from the front end side of the frame member 23 shown in FIG. At this time, when the front end of the lock pin 71 hits the hinge 75 located in front of the locking hole 72b from the front side, as shown in FIG. 26, the hinge 75 falls and the locking hole 72b is temporarily closed. Thereafter, the tip end of the lock pin 71 returns slightly back to the front end side of the frame member 23 and moves to a position where it can be inserted into the locking hole 72b.

  Next, to convert the underframe 30 (seat 1) from the one cross state (90 °) shown in FIG. 10 to the reverse cross state (270 °) shown in FIG. It is done by manual operation. In order to remove the lock pin 61 of the rotation lock mechanism 60 from the locking hole 62b, only a small stroke is required because there is no sheet metal 32 shown in FIG. Therefore, the lock of the rotation lock mechanism 60 can be released not only by the electric operation but also by the manual operation.

  In one cross state (90 °) shown in FIG. 17, after releasing the lock by the rotation lock mechanism 60, the seat back side of the seat 1 (not shown) is directed to the passage side to one direction (clockwise in FIG. 17) Rotate 180 degrees. At this time, the forward / backward locking mechanism 70 is locked, and the underframe 30 does not move forward / backward. Further, in the interlocking mechanism 50, the roller 52 on the underframe 30 side and the auxiliary roller 53 are separated outward from the other end of the guide rail 51 on the leg 11 side.

  By the way, when the seat 1 is in one cross state (90 °), when the seat 1 is turned in the reverse direction (counterclockwise in FIG. 17) to return to the long state (0 °) by manual operation, the seat 1 is the wall A1 (FIG. 8) There is a risk of interference with Therefore, in one cross state (90 °), it is necessary to limit the rotation in the other direction of the seat 1. Therefore, as shown in FIG. 32, a sheet metal 33 (equivalent to the sheet metal 32) of a predetermined thickness is attached along only one half of the periphery of the locking hole 62b which is the other direction side. As a result, in the manual operation, conversion from one cross state (90 °) to the long state (0 °) can not be performed.

When the seat 1 rotates 180 ° in one direction and reaches the reverse cross state (270 °) as shown in FIG. 20, the lock pin 61 of the rotation lock mechanism 60 is on the other short side of the underframe 30. The frame 30 is locked in a non-rotatable manner by being inserted into and engaged with the locking hole 62c. At this time, the forward / backward locking mechanism 70 is in the locked state.
The same operation is performed for the seat 1 already in the reverse cross state (270 °) by the manual operation in the case of the electric operation, but the seat 1 is in the reverse cross state (by the stopper 16 in the footrest 11 There is no further rotation in the same direction from 270 °).

  Next, when the underframe 30 (seat 1) is returned from the reverse cross state (270 °) to the one cross state (90 °), the operation is performed by electric operation or manual operation by reverse rotation of the motor 42. After releasing the lock by the rotation lock mechanism 60, in FIG. 20, the underframe 30 is rotated by 180 ° in the reverse direction (counterclockwise in FIG. 20). At this time, the forward / backward locking mechanism 70 is locked, and the underframe 30 does not move forward / backward.

  When the seat 1 rotates 180 degrees in the reverse direction and reaches one cross state (90 degrees) as shown in FIG. 17, the lock pin 61 of the rotation lock mechanism 60 is located on one short side of the underframe 30. The frame 30 is locked in a non-rotatable manner by being inserted into and engaged with the locking hole 62b. At this time, the forward / backward locking mechanism 70 is in the locked state.

  Further, in the interlocking mechanism 50, the roller 52 on the underframe 30 side and the auxiliary roller 53 are engaged again from the other end of the guide rail 51 on the footrest 11 side. At this time, the auxiliary roller 53 is moved toward the spring member 56 in the range of the guide groove 55 by biasing of the spring member 56 (see FIG. 22), so that the other end of the guide rail 51 can be reliably received. it can. In addition, as for the seat 1 which is already in one cross state (90 °) by the manual operation, the sensor 18 is turned ON, so that the rotation operation by the electric operation is controlled not to be performed.

  Next, as shown in FIGS. 33 (c) to 33 (a), in order to return the seat 1 from one cross state (90 °) to the original long state (0 °), the motor 42 is rotated by reverse rotation. It is done by operation only. As described above, the lock pin 61 of the rotation lock mechanism 60 can not overcome the thickness of the sheet metal 33 (see FIG. 32) in one half of the locking hole 62b with a small stroke by manual operation.

  In FIG. 33 (c), when the underframe 30 (seat 1) is rotated in the other direction (counterclockwise in the figure) after the lock of the rotation lock mechanism 60 is released by electric operation, linear motion is performed by the interlocking mechanism 50. It also rotates while being converted. That is, the underframe 30 rotates slightly forward to the passage side while rotating so as not to interfere with the wall surface A1 (see FIG. 8) when the underframe 30 rotates, and then 90 ° while largely retracting so as to be drawn into the wall surface A1. Rotate.

  At this time, in the interlocking mechanism 50, the roller 52 on the underframe 30 side and the auxiliary roller 53 move from the other end of the guide rail 51 on the footrest 11 side to one end, and the rotation of the underframe 30 is converted into linear motion. . Further, in the forward / backward locking mechanism 70, the lock by the lock pin 71 is released. Specifically, as shown in FIG. 29, the tip end of the side pin 76 engages with the locking hole 71a on the upper side of the lock pin 71, whereby the lock pin 71 is held in the retracted and released state.

  As shown in FIG. 33 (a), when the underframe 30 (seat 1) reaches the long state (0 °), the lock pin 61 of the rotation lock mechanism 60 is a locking hole on one long side of the underframe 30. When inserted into and engaged with 62a (see FIG. 14), the underframe 30 is non-rotatably locked. Further, in the forward / backward locking mechanism 70, the side pin 76 is disengaged from the lock pin 71 and becomes free.

  Specifically, in FIG. 16, when the lock pin 71 moves to the front of the locking hole 72a on the front side of the frame member 23, as shown in FIG. 31, the swinging member 77 is moved by the release lever 78 on the moving table 20 side. Is pushed and oscillated, and the side pin 76 disengages from the locking hole 71 a of the lock pin 71. As shown in FIG. 14, when the underframe 30 (seat 1) is in the long state (0 °), the underframe 30 is in the reverse direction (0 °) from the long state (0 °) by the stopper 17 on the leg stand 11. It does not rotate counterclockwise in the figure).

  Thus, according to the present conversion mechanism 10, the underframe 30 is disposed on the upper side of the upper surface portion 12 of the footrest 11 on the original fixed side, and the movable table 20 is interposed between the underframe 30 and the upper surface portion 12. Rotate without letting it happen. Therefore, the underframe 30 can be easily locked and restrained from the leg 11 side. When the underframe 30 is locked from the side of the leg 11 and restrained, not only the underframe 30 can not be rotated, but also advancement and retraction of the underframe 30 with respect to the foot 11 can not be performed.

  Therefore, it is possible to realize the rotation lock mechanism 60 capable of simultaneously restraining the underframe 30 so as not to rotate and to move forward and backward. According to the rotation lock mechanism 60, not only the restriction of the rotation of the underframe 30 with respect to the movable table 20 but also the restriction of the movement of the movable table 20 with respect to the leg stand 11 can be performed by one lock mechanism.

  Further, by providing the advancing / retracting locking mechanism 70 capable of restraining the underframe 30 so as to be unable to advance / retract apart from the rotating locking mechanism 60, only when the restraint by the rotating lock mechanism 60 is released can only the advancing / retracting of the seat 1 be possible. It is possible to restrain the seat 1 and to rotate the seat 1 while keeping the advancing and retreating position of the seat 1 fixed.

Next, details of control by the seat control device 100 according to the present embodiment will be described.
As shown in FIG. 3 to FIG. 7, in the passenger compartment A of the railcar, for example, four seats 1 are arranged side by side one by one on both sides in the front-rear (advancing) direction. Here, each seat 1 is divided into two groups of the odd-numbered row and the even-numbered row in the right row and the left row as described above. Hereinafter, in the figure, for the sake of explanation, the seats 1 in the right row are the seat R1, the seat R2, the seat R3 and the seat R4 in order from the head, and the seat 1 in the left row is the seat L1, the seat L2, the seat L3, It distinguishes as seat L4.

According to the seat control apparatus 100, for example, all the seats 1 can be automatically converted to any arbitrary direction for each passenger cabin A of each vehicle at a start station or an end station of a railway vehicle. However, if the states of all the seats 1 are simultaneously converted, the seats 1 adjacent to each other may interfere with each other. Therefore, conversion is sequentially performed for each of the odd rows and the even rows arranged in the front and rear. If there is no possibility that the seats 1 adjacent to each other may interfere with each other, the states of all the seats 1 may of course be converted simultaneously.
Hereinafter, conversion of the state of each seat 1 will be described for each case.

[A. When converting to one cross state]
When each seat 1 is converted to one cross state, control is started from the case where the original state of each seat 1 is in the long state or the reverse cross state. However, in the reverse cross state, since it can be converted to one cross state by manual operation, some seats 1 may already have one cross state.

[A1. When converting from long state to one cross state]
Hereinafter, the case of converting from the long state to the one cross state will be described with reference to FIG. As shown in FIG. 3 (a), in the situation where each seat 1 is in the long state, the operation is performed in the case where each seat 1 is converted to one cross state facing the terminal station at the timing when the vehicle leaves the first departure station. The switch 101 is operated to send to the control board 110 an instruction to convert each seat 1 into one cross state.

  Based on an instruction from the operation switch 101, in FIG. 3A, the control board 110 first performs an operation to convert the motor 42 of the seats R1, R3, L1, and L3 in the odd rows from the long state to one cross state. To direct. Then, as shown in FIG. 3 (b), the motors 42 of the seats R1, R3, L1, L3 in the odd rows are simultaneously rotated forward simultaneously (reverse rotation in the case of the left rows L1, L3). In the step of, the seats R1, R3, L1, and L3 in the odd-numbered rows are simultaneously converted into one cross state.

  Next, in FIG. 3B, the control board 110 instructs the motor 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows to convert the reverse cross state into one cross state. However, since the seats R1, R3, L1, and L3 in these odd-numbered rows have already been converted to one cross state in the above-described step, and this state is detected by the sensor 18, they are converted to one cross state in this step. No action is taken.

  Thereafter, in FIG. 3C, the control board 110 instructs the motor 42 of the seats R2, R4, L2, and L4 in the even-numbered rows to convert the long state into one cross state. Then, as shown in FIG. 3D, the motors 42 of the seats R2, R4, L2, L4 in the even rows are simultaneously rotated forward simultaneously (reverse rotation in the case of the left rows L2, L4). In the step of the above, the seats R2, R4, L2, and L4 in the even-numbered rows are simultaneously converted into one cross state.

Next, in FIG. 3D, the control board 110 instructs the motor 42 of the even-numbered rows R2, R4, L2, and L4 to convert the reverse cross state into the one cross state. However, since the seats R2, R4, L2, and L4 in the even-numbered rows have already been converted to one cross state in the above-described step, and such a state is detected by the sensor 18, the one cross state is in this step. There is no action to convert.
By the above series of control, as shown in FIG. 3E, all the seats 1 in the cabin A can be simultaneously converted from the long state to the one-cross state.

[A2. When converting from reverse cross state to one cross state]
Hereinafter, the case of converting from the reverse cross state to the one cross state will be described with reference to FIG. When the vehicle arrives at the first train station and the traveling direction is reversed, etc., the operation switch 101 is operated when changing from the reverse cross state for the first train station to the one for the last station shown in FIG. , An instruction to convert each seat 1 into one cross state is sent to the control board 110. In addition, before conversion control, there may be seats R2 and L2 already in one cross state by the manual operation of the passenger.

  Based on an instruction from the operation switch 101, the control board 110 first converts the motor 42 of the seats R1, R3, L1 and L3 in the odd-numbered row from the long state to one cross state in FIG. To direct. At this time, the seats R1, R3, L1, and L3 in the odd rows are in the reverse cross state, and the control panel 110 rotates the motors 42 of the seats R1, R3, L1, and L3 in the odd rows uniformly. However, each seat 1 is prevented by the stopper 16 from being converted from the reverse cross state to the one cross state regardless of the forward rotation of the motor 42. Here, since the motor 42 can be fixed and stopped, there is no risk of breakage due to overload.

  Next, in FIG. 4B, the control board 110 instructs the motor 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows to convert the reverse cross state into one cross state. Then, the motors 42 of the seats R1, R3, L1 and L3 in the odd rows are simultaneously reversely rotated (forward rotation in the case of the left rows L2 and L4), and as shown in FIG. , The seats R1, R3, L1, and L3 in the odd-numbered rows are simultaneously converted into one cross state.

  Thereafter, in FIG. 4C, the control panel 110 instructs the motor 42 of the seats R2, R4, L2, and L4 in the even number row to convert the long state into one cross state. At this time, the rearmost (right end in the drawing) seats R4 and L4 are in the reverse cross state, but the control panel 110 rotates the motor 42 of the seats R4 and L4 forward as it is. However, the conversion of the seats R4 and L4 into the one-cross state is blocked by the stoppers 16, as in the case of the odd-numbered rows in FIG. 4A described above.

  Further, in FIG. 4 (c), the seats R2 and L2 in the second row from the front side (left in the figure) are already in a cross state by the manual operation of the passenger. Therefore, with regard to these seats R2 and L2, since the sensor 18 detects that the vehicle is in the cross state, an operation to convert the seat R2 into the cross state is not performed in this step. In addition, in FIG. 4, the state of the seat 1 in the same front-back position in the right row and the left row of the cabin A respectively shows the same example, but of course the state of the seat 1 is different in the left row and the right row There is also a possibility.

  Next, in FIG. 4D, the control board 110 instructs the motor 42 of the even-numbered rows R2, R4, L2, and L4 to convert the reverse cross state into the one cross state. Then, the motors 42 of the rearmost seats R4 and L4 which are still in the reverse cross state (right end in the drawing) are simultaneously reversely rotated (forward rotation in the case of the left row L4). As shown in (e), the seats R4 and L4 are converted into one cross state.

At this time, since it is detected by the sensor 18 that the seats R2 and L2 in the second row from the front side (left in the figure) are already in one cross state, the seats described in FIG. 4C described above As in the case of R2 and L2, the operation of converting into the cross state again is not performed.
By the above series of control, as shown in FIG. 4E, all the seats 1 in the cabin A can be simultaneously converted from the reverse cross state to the one cross state.

[B. When converting to reverse cross state]
When each seat 1 is converted to the reverse cross state, control is started from the case where the original state of each seat 1 is in the long state or one cross state. However, in one cross state, since it can also be converted to the reverse cross state by manual operation, some seats 1 may already be in the reverse cross state.

[B1. When converting from long state to reverse cross state]
Hereinafter, the case of converting from the long state to the reverse cross state will be described with reference to FIG. As shown in FIG. 5 (a), when each seat 1 is in the long state, the operation switch 101 is turned to the case where the vehicle arrives at the terminal station and the like to convert each seat 1 to the reverse cross state facing the starting station. In operation, an instruction to convert each seat 1 into the reverse cross state is sent to the control board 110.

  Based on an instruction from the operation switch 101, in FIG. 5A, the control board 110 first performs an operation to convert the motor 42 of the seats R1, R3, L1, and L3 in the odd number row from the long state to one cross state. To direct. Then, the motors 42 of the seats R1, R3, L1, and L3 in the odd rows simultaneously rotate forward (reverse rotation in the case of the left rows L1 and L3), and as shown in FIG. , The seats R1, R3, L1, and L3 in the odd-numbered rows are simultaneously converted into one cross state.

  Subsequently, in FIG. 5B, the control panel 110 instructs the motor 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows to perform an operation of converting one cross state to the reverse cross state. Then, the motors 42 of the seats R1, R3, L1, and L3 in the odd rows simultaneously rotate forward (in the case of the left rows L1 and L3, reverse rotation), and as shown in FIG. , The seats R1, R3, L1, L3 in the odd-numbered rows are simultaneously converted to the reverse cross state.

  Thereafter, in FIG. 5C, the control board 110 instructs the motor 42 of the seats R2, R4, L2, and L4 in the even-numbered rows this time to convert the long state into one cross state. Then, the motors 42 of the seats R2, R4, L2, L4 in the even rows are simultaneously rotated forward simultaneously (reverse rotation in the case of the left rows L2, L4), and by this step, as shown in FIG. , The seats R2, R4, L2 and L4 in the even rows are simultaneously converted into one cross state.

Subsequently, in FIG. 5D, the control board 110 instructs the motor 42 of the even-numbered rows R2, R4, L2, and L4 to perform an operation to convert one cross state into a reverse cross state. Then, the motors 42 of the seats R2, R4, L2, L4 in the even rows are simultaneously rotated forward simultaneously (reverse rotation in the case of the left rows L2, L4), and as shown in FIG. The even-numbered seats R2, R4, L2, and L4 are also simultaneously converted to the reverse cross state.
By the above series of control, as shown in FIG. 5E, all the seats 1 in the cabin A can be simultaneously converted from the long state to the reverse cross state.

[B2. When converting from one cross state to the reverse cross state]
Hereinafter, a case where one cross state is converted to a reverse cross state will be described with reference to FIG. When the vehicle arrives at the terminal station and the traveling direction is reversed, the operation switch 101 is operated when converting from the one crossing state for the terminal station shown in FIG. 6A to the reverse crossing state for the starting station. An instruction to convert each seat 1 to the reverse cross state is sent to the control board 110. In addition, before conversion control, there may be seats R2 and L2 which are already in the reverse cross state by the manual operation of the passenger.

  Based on an instruction from the operation switch 101, in FIG. 6A, the control panel 110 first performs an operation to convert the motor 42 of the seats R1, R3, L1, and L3 in the odd-numbered row from the long state to one cross state. To direct. However, since the seats R1, R3, L1, and L3 in the odd rows are originally in one cross state, when this state is detected by the sensor 18, an operation to convert into one cross state is performed in this step. Absent.

  Next, in FIG. 6B, the control board 110 instructs the motor 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows to perform an operation to convert one cross state to the reverse cross state. Then, the motors 42 of the seats R1, R3, L1, and L3 in the odd rows simultaneously rotate forward (reverse rotation in the case of the left rows L1 and L3), and as shown in FIG. , The seats R1, R3, L1, L3 in the odd-numbered rows are simultaneously converted to the reverse cross state.

  Thereafter, in FIG. 6C, the control panel 110 instructs the motor 42 of the even-numbered rows R2, R4, L2, and L4 to convert the long state into one cross state. At this time, the seats R2 and L2 in the second row from the front (left in the figure) are in the reverse cross state, and the control panel 110 rotates the motors 42 of the seats R2 and L2 in the same direction. However, the seats R2 and L2 are prevented by the stopper 16 from being converted from the reverse cross state to the one cross state regardless of the forward rotation of the motor 42. Here, as described above, the motor 42 can be hit and stopped.

  Further, in FIG. 6C, the rearmost (right end in the drawing) seats R4 and L4 of the even-numbered rows are originally in one cross state. Therefore, with regard to these seats R4 and L4, since it is detected by the sensor 18 that one seat is in the cross state, an operation for converting the seat R4 into the one cross state is not performed in this step. In FIG. 6, the states of the seats 1 at the same front and back position in the right and left rows of the cabin A respectively show the same example, but of course the states of the seats 1 are different between the left and right rows. There is also a possibility.

  Next, in FIG. 6D, the control board 110 instructs the motor 42 of the even-numbered rows R2, R4, L2, and L4 to perform an operation to convert one cross state into a reverse cross state. Then, the motors 42 of the seats R4, L4 on the rearmost side (right end in the figure) still in one cross state rotate forward all at once (reverse rotation in the case of the left row L4). As shown in 6 (e), the last seats R4 and L4 are also converted into one cross state.

At this time, the seats R2 and L2 in the second row from the front (left in the figure) are in the reverse cross state, and the control panel 110 rotates the motors 42 of the seats R2 and L2 in the same direction. However, as described above, the seats R2 and L2 are prevented from being converted to the one-cross state by the stoppers 16.
By the above series of control, as shown in FIG. 6E, all the seats 1 in the cabin A can be simultaneously converted from one cross state to the reverse cross state.

[C. When converting to long state]
When each seat 1 is converted to the long state, control is started from the case where the original state of each seat 1 is in the one cross state or the reverse cross state.
Hereinafter, the case where each seat 1 is converted from any state to the long state will be described with reference to FIG.

  As shown in FIG. 7A, in a situation where each seat 1 is in one cross state or reverse cross state, the operation is performed in the case where each seat 1 is converted to the long state due to a wide passage etc. of the cabin A. By operating the switch 101, an instruction to convert each seat 1 to the long state is sent to the control board 110.

  Based on an instruction from the operation switch 101, in FIG. 7A, the control board 110 first performs an operation to convert the motor 42 of the seats R1, R3, L1, and L3 in odd-numbered rows from the reverse cross state to one cross state. To indicate. Since the seats R1, R3, L1, and L3 in the odd-numbered rows are all in the reverse cross state, the motors 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows reversely rotate all at once (left row L1, L3 In this case, as shown in FIG. 7B, the seats R1, R3, L1, and L3 in the odd-numbered rows are simultaneously converted into one cross state by this step.

  Next, in FIG. 7B, the control panel 110 instructs the motor 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows to perform an operation of converting one cross state into a long state. Then, the motors 42 of the seats R1, R3, L1, and L3 in the odd rows are simultaneously reversely rotated (forward rotation in the case of the left rows L1 and L3), and as shown in FIG. , The seats R1, R3, L1, and L3 in the odd-numbered rows are simultaneously converted to the long state.

  Thereafter, in FIG. 7C, the control board 110 instructs the motor 42 of the seats R2, R4, L2, and L4 in the even number row to convert the reverse cross state into one cross state. Then, at the rearmost (right end in the drawing) seats R4 and L4 that were in the reverse cross state, the motor 42 rotates in the reverse direction (forward rotation in the case of the left row L4). As shown in), the seats R4 and L4 are converted into one cross state.

  At this time, in FIG. 7C, the seats R2 and L2 in the second row from the front (left in the figure) are originally in a cross state from the beginning. Therefore, with regard to these seats R2 and L2, since the sensor 18 detects that the vehicle is in the cross state, an operation to convert the seat R2 into the cross state is not performed in this step. Note that FIG. 7 also shows an example in which the states of the seats 1 at the same longitudinal position are the same in the right and left rows of the cabin A, but of course the states of the seats 1 are different between the left and right rows. There is also a possibility.

Subsequently, in FIG. 7D, the control panel 110 instructs the motor 42 of the seats R2, R4, L2, and L4 in the even-numbered rows to perform an operation of converting one cross state into a long state. Then, the motors 42 of the seats R2, R4, L2, L4 in the even rows are simultaneously reversely rotated (forward rotation in the case of the left rows L2, L4), and as shown in FIG. 7 (e) by this step. The even-numbered seats R2, R4, L2, and L4 are simultaneously converted to the long state.
By such a series of control, as shown in FIG. 7 (e), all the seats 1 in the cabin A can be simultaneously converted to the long state.

  As described above, according to the control of the seat control device 100, each seat 1 is placed in each seat 1 regardless of whether it is in the long state, one cross state, or reverse cross state by electric or manual operation. It is possible to control the operation of the motor 42 with only the minimum unified operation instruction signal and convert the seat 1 into a desired state as shown in FIG. As a result, the conversion of the state of the seat 1 does not take time, and the plurality of seats 1 can also be converted simultaneously in a short time, and the operation control of the conversion can be easily realized by a simple program or parts. .

  In particular, the seat control apparatus 100 includes only one sensor 18 that detects that the seat 1 is in one cross state where the probability of reaching the position (via) is the highest among the three states of the seat 1. Then, when the control panel 110 converts the seat 1 from the long state or the reverse cross state to the one cross state, when the sensor 18 detects that the seat 1 is already in the one cross state, the operation to convert the seat 1 into the one cross state is Not performed. As a result, in the conversion of the seat 1, the use of only one sensor 18 can eliminate unnecessary driving of the most frequent motor 42.

  Further, in the seat control device 100, when an operation to convert the seat 1 from any one state to another state is instructed, the motor 42 is uniformly rotated if the seat 1 is under the predetermined condition described above. Thereby, the control flow for selectively operating the motor 42 can be eliminated as much as possible, and the control can be simplified. Furthermore, the blocking of the conversion of the seat 1 under predetermined conditions which is not originally supposed can also be blocked mechanically simply by the stops 16, 17 without going through complicated control flows. Here, since the motor 42 can be fixed and stopped, there is no risk of breakage due to overload.

  In the seat control apparatus 100 according to the present embodiment, control is performed with time division by dividing the seat 1 into an odd-numbered row 1 and a seat 1 from an even-numbered row. As a result, the seats 1 adjacent to each other do not operate at the same time, and every other seat 1 operates simultaneously at the same time, so the overall operation time is shortened as much as possible. Interference during operation can be prevented.

  Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and any changes or additions may be made without departing from the scope of the present invention. Included in the invention. For example, the specific shapes of the footrest 11, the movable stand 20, the underframe 30, and the like are not limited to those illustrated.

  Moreover, although the example of the seat 1 demonstrated the example of 2 seaters in the said embodiment, the seat 1 for 3 seaters or 1 seater may be sufficient. In addition, all the seats 1 in the cabin A are identical to each other, but, for example, the seats 1 arranged in the right row are different from those in the left row for three people, etc. It is good.

  In the above embodiment, an example in which the seat 1 is converted into the long state, the one cross state, and the reverse cross state as the three states of the seat 1 has been described, but the state of the seat 1 is limited to the horizontal direction. Alternatively, for example, it may be determined by the backrest of the seat 1 or the tilt angle or posture of the seat portion. Further, in the above embodiment, each seat is divided into two groups of an odd number row and an even number row, but the definition of the grouping is not particularly limited, for example. Conceivable.

  The avoiding portion 12a provided on the upper surface portion 12 of the footrest 11 is a bay-like notch which is recessed from the short side on the front side of the upper surface portion 12 to the approximate center. It is sufficient that the upper surface 12 does not interfere with the rotation shaft 41 only at the location. Therefore, the avoiding portion may be, for example, an elongated hole or groove provided in the upper surface portion 12 so as to include the movement trajectory of the rotating shaft 41.

  Furthermore, the interlocking mechanism 50 is not limited to the one provided with the guide rail 51. That is, the interlocking mechanism may be configured by a cam provided on the lower side of the underframe 30 and a roller-shaped cam follower provided on the upper surface portion 12 of the footrest 11. In this cam-type interlocking mechanism, by rotating the cam while pressing it against the cam follower, this rotational force is also converted into linear motion of the moving table 20, and the seat 1 is changed from the long state to one cross state or one cross state It can be converted to the long state.

  INDUSTRIAL APPLICABILITY The present invention is widely used as a seat control device for seats for theater, home, and office chairs, as well as seats for vehicles installed in passenger compartments such as railway cars, aircraft, automobiles, and ships. be able to.
