Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle seat group in which a plurality of seats are provided in a vehicle such as a railway vehicle and a bus, and more particularly to a vehicle seat group in which the arrangement of the plurality of seats can be switched.
[0002]
[Prior art]
In vehicles such as railway cars and buses, bench-type seats with long seats and backrests are provided along the side walls of the vehicle so that the backrest faces sideways with respect to the direction of travel of the vehicle. There is something, and this is called “long seat” in the industry.
In addition, there are multiple seats with seats, backrests and armrests arranged so that the back surface of each seat faces the traveling direction or anti-advancing direction of the vehicle. "
[0003]
[Problems to be solved by the invention]
Each of the long seat and the cross seat has advantages and disadvantages.
In other words, the long seat can take a large space for standing seats and aisles, so it is suitable for commuting and attending school. However, the seating comfort is not necessarily good because the back surface faces sideways with respect to the traveling direction of the vehicle, and the body of the seated person swings in the left-right direction when viewed from the seated person. Therefore, it is not very suitable when it does not fit.
On the other hand, the cross seat is comfortable in sitting because the back surface is directed in the traveling direction of the vehicle and the back rest receives the shaking of the seated person's body in the front-rear direction. Therefore, it is suitable when it does not fit. However, the space for standing seats and aisles is small, so it is not very suitable when crowded.
[0004]
In this way, the advantages and disadvantages of long seats and cross seats are the opposite, and it is very difficult to choose which seat to use. Regardless of which seat you choose, there are disadvantages depending on the time of day. There was a problem. This is because, in the past, long seats have always been fixed in that state, and some of the cross seats can be turned 180 degrees, but they are always cross seats. .
[0005]
Therefore, the object of the present invention is to solve the above-mentioned problems and to switch a plurality of seats to a long arrangement corresponding to the conventional long seats when a vehicle is mixed, so as to increase the space for standing seats and passages. To provide a long / cross arrangement switchable vehicle seat group that gives priority to sitting comfort by switching a plurality of seats to a cross arrangement equivalent to a conventional cross seat when the vehicle does not jam It is in.

(3) As shown in FIG. 3, a “cross arrangement for B station” in which the back surface 15a of each seat 10 faces the traveling direction to the B station (tentative name) of the railway vehicle 1
An array switching device for switching to is provided.
This arrangement switching device is composed of the following rotation mechanism 21, slide mechanism 22, and control device 23.
[0020]
[Rotating mechanism 21]
The rotation mechanism 21 is for rotating the seat frame 13, the seat portion 14, the backrest 15, the headrest 16 and the armrest 17 (hereinafter referred to as the seat portion 14 and the backrest 15) of each seat 10. It is configured as follows.
A rotary spindle 20 is rotatably mounted by a thrust bearing 25 on the center of the slide base plate 122 of the slide base 12, and a seat frame 13 is attached to the upper part of the rotary spindle 20 to rotate together with the rotary spindle 20. It is supposed to be. Below the slide base plate 122, a large-diameter gear 31 that is attached to the lower part of the rotary main shaft 20 and rotates together with the rotary main shaft 20, a small-diameter gear 32 that meshes with the gear 31, and the gear 32 is pivotally supported. An electromagnetic clutch 33 and an electric motor 34 for rotation with a speed reducer connected to the electromagnetic clutch 33 are provided.
[0021]
Therefore, when the electric motor 34 for rotation rotates, the rotation main shaft 20 rotates through the electromagnetic clutch 33 and the gears 32 and 31, and the seat portion 14 and the backrest 15 and the like rotate together. Further, by changing the rotation direction of the electric motor 34 for rotation, the rotation direction of the seat portion 14, the backrest 15, etc. can be changed to the clockwise direction or the counterclockwise direction of the plane.
[0022]
[Slide mechanism 22]
When the slide mechanism 22 is in the long arrangement, as shown in FIGS. 4, 5, 8, and 9, the rotation center of the rotation mechanism 21 (in this embodiment, the rotation center of the rotation main shaft 20) is the side wall of the railway vehicle 1. 3, slide to the long position P 1 approaching 3, and in the cross arrangement, the rotation center of the rotation mechanism 21 is moved to the cross position P 2 away from the side wall 3 of the railway vehicle 1 as shown in FIGS. 6, 7, 11 and 12. When the seat portion 14 and the backrest 15 are rotated, the rotation allowable position P3 in which the rotation center of the rotation mechanism 21 is further away from the side wall 3 of the railway vehicle 1 than the cross position P2, as shown in FIGS. It is intended to slide.
[0023]
In this embodiment, the distance from the side wall 3 to the long position P1 is 405 mm, the distance from the side wall 3 to the cross position P2 is 500 mm (thus 95 mm between P1 and P2), and the distance from the side wall 3 to the rotation allowable position P3 is 555 mm. (Thus, the distance between P2 and P3 is 55 mm).
[0024]
As shown in FIGS. 4 and 5, when the rotation center of the rotation mechanism 21 is at the long position P1, the gap between the upper portion of the backrest 15 of the seat 10 in the long arrangement and the side wall 3 is minimized, but the seat portion 14. Rotation of backpack 15 etc. becomes impossible. That is, in the seat 10 of the present embodiment, the maximum rotation locus is drawn on the upper end side portion of the backrest 15, and the maximum rotation radius by the same portion is 535 mm. Therefore, if the seat portion 14 and the backrest 15 are to be rotated at the same position P1, the upper end side portion of the backrest 15 immediately contacts the side wall 3 and cannot be rotated.
[0025]
As shown in FIGS. 6 and 7, when the rotation center of the rotation mechanism 21 is at the cross position P2, the gap between the armrest 17 and the side wall 3 of the seat 10 in the cross arrangement is minimized. The rotation of 15 etc. is limited. That is, if the upper end side portion of the backrest 15 is rotated in the direction approaching the side wall 3, the upper end side portion of the backrest 15 hits the side wall 3 during the rotation due to the dimensional relationship, and the rotation is impossible. However, if the upper end side portion of the back rest 15 does not approach the side wall 3 (that is, the direction in which the front end corner portion of the seat portion 14 approaches the side wall 3) and the angular range, it can be rotated. This is because the rotation radius of the front end corner portion of the seat portion 14 having the largest rotation radius excluding the backrest 15 is less than 500 mm and does not hit the side wall 3.
[0026]
As shown in FIG. 19 (a3) and the like, when the rotation center of the rotation mechanism 21 is at the rotation allowable position P3, the gap between the armrest 17 of the seat 10 and the side wall 3 becomes large, and the seat portion 14 and the backrest 15 Etc. can be freely rotated.
The slide mechanism 22 is configured as follows.
[0027]
The guide rail 115 and the slide rail 121, and the slide base plate 122 and the pair of skirt plates 123 provided so as to be slidable thereby are a part of the slide mechanism 22. A power cylinder 35 extending in the sliding direction, such as the slide base plate 122, is provided in the inner and lower portions of the fixed base 11. The power cylinder 35 includes a cylinder body 36, an electric motor 37 for sliding that drives the cylinder body 36, and a gear device 38. A notch 40 is formed from the upper surface to the center of the portion near the tip of the rod 39 where the power cylinder 35 advances and retreats, and an engagement pin 41 is fitted into the notch 40. The engaging pin 41 is inserted into and engaged with a vertically long slot 124 formed in the lower part of the pair of skirt plates 123.
[0028]
Therefore, when the rod 39 of the power cylinder 35 advances and retracts, the engaging pin 41 pushes or pulls the skirt plate 123, and the slide base plate 122 and the slide rail 121 slide along the guide rail 115 with the rotation mechanism 21. To do.
As shown in FIGS. 8 to 10, when the rod 39 of the power cylinder 35 is most retracted into the cylinder body 36, the rotation center of the rotation mechanism 21 slides to the long position P1.
From this state, as shown in FIGS. 13 and 14, when the rod 39 is unwound 150 mm (95 mm + 55 mm) from the cylinder body 36, the rotation center of the rotation mechanism 21 slides to the rotation allowable position P3.
From this state, as shown in FIGS. 11 and 12, when the rod 39 retracts by 55 mm into the cylinder body 36, the rotation center of the rotation mechanism 21 slides to the cross position P2.
[0029]
A long cross positioning board 24 is rotatably mounted around the thrust bearing 25 immediately above the slide base plate 122, and between the long cross positioning board 24 and the slide base plate 122 and the long cross positioning board 24. A resin disk 26 is interposed between the seat frame 13 and the seat frame 13. A long positioning leg 27 having a short protruding length and a cross positioning leg 28 having a long protruding length protrude from two positions of the outer periphery of the long cross positioning board 24 perpendicular to each other. , 30 are provided. On the top plate 113 of the fixed base 11, an engagement column 42 that projects into the engagement recesses 29 and 30 is projected.
The long cross positioning board 24 rotates with the seat frame 13 only at the time of switching between the long arrangement and the cross arrangement by an interlock mechanism (not shown), and the engagement recess 29 of the long positioning leg 27 or the engagement of the cross positioning leg 28 is engaged. The mating recesses 30 are respectively engaged with the engagement columns 42 to position the long position P1 or the cross position P2.
[0030]
[Control device 23]
As shown in FIGS. 17 and 18, the control device 23 of the present embodiment is configured to rotate the power cylinder 35 and the rotation cylinders in six seats (the three seats 10 in the right row and the three seats 10 in the left seat opposite thereto). The electric motor 34 and the electromagnetic clutch 33 can be controlled. Of course, since one train vehicle 1 has more seats (for example, 18 legs), the capacity of the control device can be increased so that all the seats can be controlled by one control device.
The control device 23 according to the present embodiment is configured around a sequencer SQ and includes three terminal boards TB1, TB2 and TB3. A 200-volt AC power supply A1, a 100-volt DC power supply D1, and a ground E are connected to the first terminal board TB1, and AC is supplied from the AC power supply A1 to the sequencer SQ through the power switch S4 and the noise filter F. Is done.
[0031]
The power cylinders 35 (specifically, electric motors 37 for sliding) of the six seats 10 are commonly connected to the second terminal board TB2, and the electric motors 34 for rotation of the six seats 10 are independent of each other. Connected. All the power cylinders 35 are connected to the AC power supply A1 via the contacts of the electromagnetic contactors M0 and M1 controlled by the sequencer SQ. Each electric motor 34 for rotation is connected to AC power supply A1 via the contacts of electromagnetic contactors M2, M3, M4, M5, M6, and M7 controlled by sequencer SQ.
[0032]
The electromagnetic clutch 33 of the six seats 10 is commonly connected to the third terminal board TB3, and all the electromagnetic clutches 33 are connected to the DC power source D1 through the contacts of the electromagnetic contactor M8 controlled by the sequencer SQ. Has been. M9 is an electromagnetic contactor for intermittently supplying current to the coils of the electromagnetic contactors M0 to M8 and relays R4 and R5 described later.
The third terminal board TB3 is connected to a limit switch LS1 for detecting that the right row of seats 10 is in a long arrangement and a limit switch LS2 for detecting that the left row of seats 10 is in a long arrangement. Are connected to the sequencer SQ via relays R4 and R5, respectively. As shown in FIGS. 10 and 12, the limit switches LS1 and LS2 are attached to the top plate 113 of the fixed base 11, and are turned on when the slide base plate 122 of the slide base 12 approaches in the long arrangement. Yes.
[0033]
Also, the third terminal board TB3 has a switching signal T1 from the driver's seat (not shown) to the A station-oriented cross array and a switching signal T2 from the driver's seat to the long array. And a switching signal T3 to the cross arrangement for the B station, which is commanded from the driver's seat, can be input. Each switching signal T1, T2, T3 is input to the sequencer SQ via relays R1, R2, R3.
Further, the control panel of the control device 23 is provided with switches S1, S2 and S3 operated by the crew for each control device 23. S1 is a changeover switch to the cross arrangement for the A station, and S2 is a crossover switch. The switch is a switch from the array to the long array, and S3 is a switch to the cross array for the B station.
Note that the switching from the cross arrangement to the long arrangement is the same both when switching from the cross arrangement for station A to the long arrangement and when switching from the cross arrangement for station B to the long arrangement.
[0034]
Next, the other structure of the seat 10 will be described. As shown in FIGS. 8, 10, 15, 16 and the like, the unlocking pedal 45 tilts around the shaft 46 on the skirt plate 123 of the slide base 12. A wire 50 is connected to the rear of the pedal 45 and pulled along with the rotation of the electric motor 34 for rotation. A lock pin 47 extending upward is attached in the middle of the unlocking pedal 45, and the lock pin 47 always passes through the long cross positioning disk 24 and the through hole 48 of the resin disk 26, and the locking hole 49 of the seat frame 13. To prevent the seat 14 and the back 15 from rotating unexpectedly.
Then, as shown in FIG. 15, when the unlocking pedal 45 is stepped on or when the unlocking pedal 45 is pulled by the wire 50 along with the rotation of the electric motor 34 for rotation, the lock pin 47 is moved to the seat frame 13 and the long frame. -The seat 14, the backrest 15, and the like are in a state of being able to rotate through the locking holes 49 of the cross positioning board 24.
[0035]
Further, a manual slide lever 52 is attached to the skirt plate 123 of the slide base 12 so as to be tiltable about a shaft 53, and is urged in the back direction by a spring 54. A hook portion 55 that engages with the engagement pin 41 is formed at the back of the manual slide lever 52, and a long hole 56 is formed at the upper end portion of the lever 52. A stop pin 57 is inserted into the long hole 56, and the stop pin 57 is also inserted into the back of a long hole 59 with a front recess 58 formed in the skirt plate 123. It is biased downward. Therefore, the hook portion 55 always engages the engaging pin 41 with the notch 40 of the rod 39.
When the power cylinder 35 stops operating due to some trouble, as shown in FIG. 16, if the manual slide lever 52 is pulled forward, the hook portion 55 moves the engaging pin 41 along the elongated hole 124. Therefore, regardless of the power cylinder 35, the slide base 12 can be manually slid.
[0036]
The railcar seat group of the present embodiment configured as described above is used by switching the arrangement in various cases as follows. Since the three seats in the right row and the three seats in the left row controlled by the control device 23 rotate and slide symmetrically, the following three rows in the right row are shown in FIGS. 19, 20, and 21. Only the seat 10 is shown, and illustration of the three seats in the left column is omitted.
[0037]
[Case I (long arrangement → cross arrangement for station B) FIG. 19 (a ...)]
Initially, as shown in FIG. 1, it is assumed that the seats 10 are in a long arrangement. At this time, as shown in FIGS. 8 to 10, the rod 39 of the power cylinder 35 is most retracted into the cylinder body 36, the rotation center of the rotation mechanism 21 is at the long position P <b> 1, and the long positioning foot 27 is engaged. The joint recess 29 is engaged with the engagement column 42.
Then, when the railway vehicle 1 is not jammed and arrives at the final A station, a switching signal T3 to the cross arrangement for the B station is sent from the driver's seat to each control device 23 in order to improve the sitting comfort. The seat 10 is switched from the long arrangement in FIG. 1 to the B station cross arrangement in FIG. 3 by sending or operating the switch S3 to the B station cross arrangement in each control device 23. At the time of this switching, the control device 23 controls the power cylinder 35 of the slide mechanism 22, the electric motor 34 for rotation of the rotation mechanism 21, and the electromagnetic clutch 33 in the following order.
[0038]
(1) The limit switches LS1 and LS2 detect that the right and left row seats 10 are in the long arrangement, and as shown in FIGS. 13 and 14, the rods 39 of the power cylinders 35 of the respective seats 10 are moved simultaneously. Then, 150 mm (95 mm + 55 mm) is fed out from the cylinder body 36, and the rotation center of the rotation mechanism 21 is slid from the long position P1 to the rotation allowable position P3 over the cross position P2. Each seat 10 is in the state shown in FIGS. 19 (a1) to (a2).
[0039]
(2) Subsequently, the electromagnetic clutch 33 of each seat 10 is connected, and as shown in FIGS. 19 (a2) and (a3), the electric motor 34 for rotation is operated one by one from the head side seat 10 one by one. Rotate the part 14, back 15 and so on 90 degrees counterclockwise to the B station. Specifically, as described above, as the rotating electric motor 34 rotates, the unlocking pedal 45 is first pulled by the wire 50, and the lock pin 47 is pulled from the locking hole 49 of the seat frame 13 and the long cross positioning panel 24. As a result, the seat 14, the backrest 15, and the like become rotatable, and are subsequently driven to rotate (hereinafter the same in each case). At this time, as shown in FIGS. 13 and 14, the cross positioning leg 28 faces the engaging column 42, but the engaging recess 30 is detached from the engaging column 42. After the rotation, the electromagnetic clutch 33 of each seat 10 is released.
It is also possible to rotate the seat 14 and back 15 of the two seats 10 that are skipped, and then rotate the seat 14 and back 15 and so on of the seat 10 that has been skipped. When the seat part 14 and the backrest 15 etc. of the mating seat 10 can rotate simultaneously without interfering with each other, the seat part 14 and the backrest 15 etc. of all the seats 10 may be rotated simultaneously (hereinafter, 90 degrees). Same for rotation).
[0040]
(3) Subsequently, as shown in FIGS. 11 and 12, the rods 39 of the power cylinders 35 of the respective seats 10 are simultaneously retracted by 55 mm into the cylinder body 36, and the rotation center of the rotation mechanism 21 is set to the cross position P2. Slide. At this time, the engagement recess 30 of the cross positioning leg 28 engages with the engagement column 42. Each seat 10 is in the state shown in FIG. 19 (a4), that is, in the cross arrangement for the B station in FIG.
Thus, the reason why the rotation center of the rotation mechanism 21 is returned from the rotation allowable position P3 to the cross position P2 is to increase the space for the passage. That is, if the rotation center of the rotation mechanism 21 remains at the rotation allowable position P3, a useless gap remains between the armrest 17 and the side wall 3, so that the gap is minimized and the passage space is maximized. It is.
[0041]
[Case II (long arrangement → cross arrangement for A station) FIG. 19 (b...)]
Next, as in the case I, it is assumed that the seat 10 is initially in a long arrangement. Then, when the railway vehicle 1 is not jammed and arrives at the final B station as opposed to the case I, the switching signal T1 to the cross arrangement for the A station is sent from the driver's seat to each control device 23. Alternatively, the crew member switches the seat 10 from the long arrangement in FIG. 1 to the cross arrangement in the A station direction in FIG. 2 by operating the switch S1 to the A station direction cross arrangement in each control device 23. At the time of switching, the control device 23 controls the power cylinder 35, the electric motor 34 for rotation, and the electromagnetic clutch 33 in the following order.
[0042]
(1) Same as (1) in Case I. Refer to FIGS. 19 (b1) and (b2).
(2) Same as (2) in Case I, with the seat 10 facing the B station. Refer to FIGS. 19B2 and 19B3.
(3) Same as (3) in Case I. Refer to FIG. 19 (b4).
(4) Subsequently, the electromagnetic clutch 33 of each seat 10 is reconnected, and as shown in FIGS. 19 (b5) and (b6), the electric motors 34 for rotating the two seats 10 are operated. Then, the electric motor 34 for rotating the seat 10 that has been skipped is operated to rotate the seats 14 and the backrest 15 etc. by 180 degrees counterclockwise so that they are directed to the A station. During this rotation, the rotation center of the rotation mechanism 21 remains at the cross position P2, but the back rest 15 rotates in a direction not approaching the side wall 3, so that the upper end side portion of the back rest 15 does not hit the side wall 3. After the rotation, the electromagnetic clutch 33 of each seat 10 is released.
In addition, the seat portion 14 and the backrest 15 etc. may be rotated one by one from the head side seat 10 one by one, or the seat portion 14 and the backrest 15 etc. of the adjacent seat 10 may be simultaneously not interfering with each other. In the case where it is possible to rotate, the seat portion 14 and the backrest 15 of all the seats 10 may be rotated at the same time (hereinafter, the same for 180 degrees rotation).
[0043]
[Case III (A crossing for station A → long arrangement) FIG. 20 (a ...)]
Next, when the railway vehicle 1 comes into contact with commuting, attending school, etc., and arrives at the final station A, each control is comprehensively controlled from the driver's seat to increase the space for standing seats and passages. A switching signal T2 from the cross arrangement to the long arrangement is sent to the device 23, or the crew member operates the changeover switch S2 from the cross arrangement to the long arrangement for each control device 23, so that the seat 10 is directed to the station A in FIG. Switch from the cross array to the long array in FIG. At the time of this switching, the control device 23 controls the power cylinder 35 of the slide mechanism 22, the electric motor 34 for rotation of the rotation mechanism 21, and the electromagnetic clutch 33 in the following order.
[0044]
(1) The electromagnetic clutch 33 of each seat 10 is connected, and as shown in FIG. 20 (a1), the electric motor 34 for rotation of the two seats 10 that are jumped one by one is actuated. The electric motor 34 for rotation is actuated to rotate each seat 14, backrest 15, etc. 180 degrees clockwise in the plane, and once set to a cross arrangement for the B station. During this rotation, the rotation center of the rotation mechanism 21 remains at the cross position P2, but the back rest 15 rotates in a direction not approaching the side wall 3, so that the upper end side portion of the back rest 15 does not hit the side wall 3. After the rotation, the electromagnetic clutch 33 of each seat 10 is released.
Note that there may be a seat that is already facing the B station by manual rotation by the passenger before the motor is operated, but the seat is not rotated by the sliding of the electromagnetic clutch 33 during this rotation.
[0045]
(2) Subsequently, as shown in FIGS. 13 and 14, the rods 39 of the power cylinders 35 of the respective seats 10 are fed out from the cylinder body 36 all at once, and the rotation center of the rotation mechanism 21 is rotated from the cross position P2 to the rotation allowable position. Slide to P3. Each seat 10 is in the state shown in FIGS. 20 (a1) to (a2).
[0046]
(3) Subsequently, the electromagnetic clutch 33 of each seat 10 is reconnected, and as shown in FIGS. 20 (a3) and (a4), the electric motor 34 for rotation is operated one by one from the head seat 10 one by one. Rotate the seat 14, back 15 and the like 90 degrees clockwise in the plane. After the rotation, the electromagnetic clutch 33 of each seat 10 is released.
[0047]
(4) Subsequently, as shown in FIGS. 8 and 9, the rods 39 of the power cylinders 35 of the seats 10 are simultaneously retracted into the cylinder body 36, and the rotation center of the rotation mechanism 21 is slid to the long position P1. . At this time, the engaging recess 29 of the long positioning leg 27 engages with the engaging column 42. Each seat 10 is in the state shown in FIG. 20 (a5), that is, in the long arrangement shown in FIG.
[0048]
[Case IV (cross arrangement for station B → long arrangement) FIG. 20B ...]
Next, when the railway vehicle 1 comes into contact with the vehicle as in the case III and arrives at the terminal B station opposite to the case III, the switching signal T2 is sent or the switching switch S2 is sent in the same manner as in the case III. , The seat 10 is switched from the cross arrangement for the B station in FIG. 3 to the long arrangement in FIG. 1. At the time of this switching, the control device 23 controls the power cylinder 35 of the slide mechanism 22, the electric motor 34 for rotation of the rotation mechanism 21, and the electromagnetic clutch 33 in the following order.
[0049]
{Circle around (1)} As in case III {circle around (1)}, the electromagnetic clutch 33 of each seat 10 is connected and the electric motor 34 for rotation is operated. However, since the seat 10 is already in the cross arrangement for the B station, the electromagnetic clutch 33 Does not rotate by sliding. Refer to FIG. 20 (b1).
Note that there may be a seat that is directed to the A station by the manual rotation by the passenger before the motor is operated, but the seat rotates in the same manner as in the case III (1) and is directed to the B station.

(3) Same as (3) in Case III. Refer to FIGS. 20 (b3) and (b4).
(4) Same as (4) in case III. Refer to FIG. 20 (b5).
[0050]
[Case V (cross arrangement for station A → cross arrangement for station B) FIG. 21 (a)]
Next, when the railway vehicle 1 arrives at the final A station and the traveling direction is reversed, the cross arrangement for the A station in FIG. 2 before the reversal is switched to the cross arrangement for the B station in FIG. 3 after the reversal. In the same manner as in Case I, the driver seats collectively send a switching signal T3 to the B station cross array to each control device 23, or the crew member switches to the B station cross array for each control device 23. The switch S3 is operated. At the time of this switching, the control device 23 controls the electric motor 34 for rotation and the electromagnetic clutch 33 in the following order.
[0051]
(1) Since the limit switches LS1 and LS2 do not detect the long arrangement of the seat 10 even if the switching signal T3 is sent or the switching switch S3 is operated in exactly the same manner as in the case I, the control method is different from that in the case I. . That is, the electromagnetic clutch 33 of each seat 10 is connected, and as shown in FIGS. 21 (a1) and 21 (a2), the electric motor 34 for rotation of the two seats 10 is operated, and then the seats that have been skipped are operated. The 10 rotation electric motors 34 are actuated to rotate the seats 14 and the backrest 15 etc. 180 degrees clockwise in the plane, so that a cross arrangement for the B station is obtained. During this rotation, the rotation center of the rotation mechanism 21 remains at the cross position P2, but the back rest 15 rotates in a direction not approaching the side wall 3, so that the upper end side portion of the back rest 15 does not hit the side wall 3. After the rotation, the electromagnetic clutch 33 of each seat 10 is released.
Note that there may be a seat that is already facing the B station by manual rotation by the passenger before the motor is operated, but the seat is not rotated by the sliding of the electromagnetic clutch 33 during this rotation.
[0052]
[Case VI (cross arrangement for station B → cross arrangement for station A) FIG. 21 (b...)]
Next, when the railway vehicle 1 arrives at the final B station and the traveling direction is reversed, the crossing arrangement for the B station in FIG. 3 before the reversal is switched to the cross arrangement for the A station in FIG. In the same manner as in the case II, the switching signal T1 to the crossing arrangement for the A station is sent from the driver's seat to each control device 23 in a centralized manner, or the crew member switches to the cross arrangement for the A station for each control device 23. The switch S1 is operated. At the time of this switching, the control device 23 controls the electric motor 34 for rotation and the electromagnetic clutch 33 in the following order.
[0053]
(1) Since the limit switches LS1 and LS2 do not detect the long arrangement of the seat 10 even if the switching signal T1 is sent or the changeover switch S1 is operated in the same manner as in the case II, the control method is different from the case II. . That is, the electromagnetic clutch 33 of each seat 10 is connected, and as shown in FIGS. 21 (b1) and (b2), the electric motor 34 for rotation of the two seats 10 that are skipped is operated, and then the seats that have been skipped are operated. 10 rotation electric motors 34 are actuated to rotate the seats 14 and the backrests 15 and the like 180 degrees counterclockwise in the plane so as to form a cross arrangement for the A station. During this rotation, the rotation center of the rotation mechanism 21 remains at the cross position P2, but the back rest 15 rotates in a direction not approaching the side wall 3, so that the upper end side portion of the back rest 15 does not hit the side wall 3. After the rotation, the electromagnetic clutch 33 of each seat 10 is released.
In some cases, there is a seat that is already directed to the station A by manual rotation by the passenger before the motor is operated, but the seat is not rotated by the sliding of the electromagnetic clutch 33 during this rotation.
[0054]
