Next, a control device for operating the vehicular rotary seat having the above-described structure and its related parts will be described.
As shown in FIG. 2, the control device of this embodiment is an electronic control device 40 including a central processing unit (CPU) 41, a motor drive circuit 42, and an alarm buzzer 43, and the motor drive circuit 42 includes 14, the slide motor 28 and the reclining motor 37 are connected. The CPU 41 also includes the seat back 3 of the seat 30.
Reclining switch 4 for reclining 5
4. A rotary protruding storage switch 45 for moving the seat 30 between a storage position at the time of normal riding and a protruding position protruding out of the door opening of the vehicle body, and the moving member 25 in the rearmost position with respect to the rotary base 20. The rearmost position detection switch 46 for detecting that there is, the front reclining position detection switch 47 for detecting that the reclining angle of the seat back 35 is equal to or less than the reference angle S that does not interfere with the rotation of the seat 30, and the same reclining angle. Reference angle S
A rear reclining position detection switch 48 for detecting the above value and a door courtesy switch (door courtesy switch) 49 for detecting that a passenger's seat door provided with the vehicle rotating seat is open are connected. . As will be described in detail below, when the CPU 41 turns on the rotary protrusion storage switch 45, the motors 14, 28, 37 via the motor drive circuit 42 based on the detection result from each switch according to the direction of movement. To move the seat 30 in the storage position during normal riding to the protruding position protruding out of the door opening of the vehicle body, or return the seat 30 in the protruding position to the storage position, and when necessary, an alarm is issued. The buzzer 43 sounds. The rotary protruding storage switch 45 is provided on the side of the seat cushion 31 or the like, and its knob is in a neutral position in a non-operating state, and a protruding side for manually moving the seat 30 in the stored position to the protruding position; Seat 30 in position
Can be operated to the storage side to return to the storage position, and returns to the neutral position when the hand is released.

The operation of the vehicular rotary seat according to this embodiment will be described below mainly with reference to flowcharts shown in FIGS. First, referring to FIGS. 4 to 7, a description will be given of a case where the seat 30 at the storage position during traveling (see FIG. 3A) is moved to a protruding position (see FIG. 3C) where it is easy to get on and off. In a state where the seat 30 is in the storage position, the front door (not shown) provided in the corresponding door opening B is opened, and if the user moves the knob of the rotary protrusion storage switch 45 to the protrusion side, the CPU 41 becomes the assistant. After confirming that the door corresponding to the seat 30 is open by the seat door courtesy switch 49 (not shown),
First, the alarm buzzer 43 to start the operation is sounded (step 100), and the reclining angle of the seat back 35 is the reference angle S (= the neutral position N + 14 degrees of the reclining) that does not hinder the rotation of the seat 30 (FIG. 3A). Is determined (step 101). If it is less than the reference angle S, the CPU 41 executes the reclining angle setting operation and the seat outward rotation operation in parallel. That is, in the former, the operation of the reclining motor 37 is started in a direction in which the reclining angle increases, and stopped when the reclining angle reaches the reference angle S as shown by a solid line in FIG. 3A (see steps 102 to 104). In the latter case, the operation of the rotation motor 14 is started in the direction in which the longitudinal movement base 12 advances, and the seat 30 is advanced, and at the same time, the sheet 30 is rotated outward about the rotation axis O, so that the longitudinal movement base 12 reaches the most advanced position. If the seat 30 is rotated 90 degrees, it stops (see steps 110 to 113 in FIGS. 4 and 5). During this time, the center of the turntable 16 moves by a distance A from O1 to O2, and the seat 30 is at an outward position facing the door opening B side of the vehicle body on the front side deviating from the center pillar C of the vehicle body (FIG. 3 (b)). )reference).

When the seat 30 is rotated by 90 degrees in this manner, the CPU 41 starts the operation of the reclining motor 37 again in the direction in which the reclining angle is increased to perform the seat back tilting operation, and the reclining angle passes through the door opening B. Passing angle (=
When the neutral position N + 18.5 degrees is reached, the operation is stopped (see steps 115 to 117). The CPU 41 also controls the seat 30
Is rotated by 85 degrees, it is confirmed that the reclining angle has reached the reference angle S (see step 114), and then the sheet ejecting operation is performed. This starts the operation of the slide motor 28 to advance the sheet 30 in the Y direction together with the moving member 25, and stops when the advance amount reaches 350 mm (see steps 120 to 122 in FIGS. 5 and 6). As a result, the seat 30 is in a protruding position outside the door opening B as shown in FIG. During this forward movement, the seat back 35 of the seat 30 passes through the door opening B. At this time, since the above-mentioned seat back tilting operation has been completed, the head of a disabled person or the like sitting on the seat 30 at the time of this passing is completed. No part or the like interferes with the door opening B.

At the same time when the sheet ejection operation is stopped, the CP
U41 starts the operation of the reclining motor 37 in the direction in which the reclining angle decreases, performs the seat back returning operation, and changes the reclining angle of the seat back 35 from the passing angle (see the two-dot chain line in FIG. 3 (c)). Return to a value suitable for getting on and off the seat 30 at the protruding position (= neutral position N + 6 degrees) (see the solid line in FIG. 3C) (see steps 125 to 127), and an alarm indicating that the operation has been completed. The buzzer 43 sounds (step 128), and the operation ends.

If the reclining angle of the seat back 35 is not less than the reference angle S in step 101, the CPU 41 first executes a reclining angle setting operation, and then executes a seat outward turning operation. That is, in the former, the operation of the reclining motor 37 is started in the direction in which the reclining angle decreases, and stopped when the reclining angle reaches the reference angle S (step 1 in FIG. 7).
30 to 131), and in the latter case, just like the case where the reclining angle is less than the reference angle S, the seat is turned outward (steps 100 to 113), the seat back is inclined (see steps 115 to 117), and the sheet is pushed out (steps). 120 to 122) and the seat back returning operation (see steps 125 to 127), and the alarm buzzer 43 indicating that the operation has been completed sounds (step 128).
End the operation. In this case, since the seat outward rotation operation is performed after the reclining angle setting operation is performed, it is not necessary to check the reclining angle in step 114.

Next, referring to FIGS. 8 and 9, a description will be given of a case where the sheet 30 at the protruding position (see the solid line in FIG. 3C) is returned to the storage position. In this state, the reclining angle of the seat back 35 is a value suitable for getting on and off the seat 30 (= neutral position N + 6 degrees). If the user moves the knob of the rotary protrusion storage switch 45 to the storage side,
The CPU 41 first sounds the alarm buzzer 43 to start the operation (step 200), starts the operation of the reclining motor 37 in the direction in which the reclining angle increases, performs the seat back tilting operation, and sets the reclining angle to the door opening B. When the passage angle (= the neutral position N + 18.5 degrees) is such that the passage is not hindered, the operation is stopped (see steps 201 to 203). Simultaneously with the completion of the seat back tilting operation, the CPU 41 performs a seat pull-in operation. This starts the operation of the slide motor 28 to retreat the sheet 30 together with the moving member 25 with respect to the rotary base 20, and when the retreat amount reaches 350 mm and reaches the last retreat position (see FIG. 3B). Stop (see steps 210 to 214).

In the course of the retreat, when the retreat amount reaches 175 mm (step 211), the CPU 41 starts the operation of the reclining motor 37 in a direction in which the reclining angle decreases, and sets the reclining angle to the aforementioned reference angle S. Is performed (steps 215 to 217). At this point, since the seat back 35 is substantially in the vehicle body from the door opening B, the head or the like of a disabled person sitting on the seat 30 may not interfere with the door opening B due to the reclining angle setting operation. Absent. When the retreat amount reaches 343 mm (step 212), the CPU 41 confirms that the reclining angle has reached the reference angle S (see step 218). After the position is confirmed by the retreat position detection switch 46 (not shown), the sheet is turned inward. This causes the rotation motor 14 to start operating in the direction in which the longitudinal movement base 12 is retracted, thereby causing the seat 30 to move backward together with the moving member 25, and simultaneously rotating inward around the rotation axis O, whereby the longitudinal movement base 12 is finally retracted. When the seat 30 is in the retracted position (see FIG. 3A) where the seat 30 faces forward with respect to the vehicle body, the seat retraction operation is stopped (steps 220 to 222).

Simultaneously with the completion of the sheet pull-in operation,
The CPU 41 starts the operation of the reclining motor 37 and returns the reclining angle of the seat back 35 to the reclining angle before the start of the operation of rotating and projecting the seat if the user keeps moving the knob of the rotating and projecting storage switch 45 to the storage side. When the operation is ended, the alarm buzzer 43 sounds and the operation is ended. When the hand is released from the knob of the rotary projection storage switch 45 and the knob returns to the neutral position, the operation is terminated as it is. The alarm buzzer 43 is sounded and the operation is terminated (steps 225 to 229). If the hand is released from the knob during the above operation, the rotary projection storage switch 45 returns to the inoperative state, and the operation of the vehicle rotary seat is stopped in that state.

According to the embodiment described above, the electronic control unit 40 moves the knob of the rotary projection storage switch 45 to the storage side, and the electronic control device 40 simultaneously moves the seat 30 forward and sets the seat to the outward position. Automatically performs a sheet outward rotation operation, a sheet protruding operation for projecting the seat 30 out of the door opening B, and a seat back tilting operation for setting the seat back 35 to a passage angle that does not hinder the passage of the door opening B. Executing in a predetermined sequence, the disabled person or the like seated at the storage position moves to the protruding position where the head or the like can easily get on and off without fear of the head interfering with the door opening. The convenience when getting off greatly improves.

In the above embodiment, the electronic control unit 4
0 indicates that the reclining angle setting operation for setting the seat back 35 to a reclining angle suitable for the rotation of the seat 30 is also performed in a predetermined sequence. Therefore, even if the reclining angle is increased in the storage position, the vehicle turning seat is not changed. Since it can be operated, the above-mentioned convenience is further improved. Further, in the above-described embodiment, since the seatback returning operation of returning the seatback 35 of the seat 30 moved to the protruding position to a reclining angle suitable for getting on and off is also performed in a predetermined sequence, the above-described convenience is further improved. . In the above embodiment,
When the reclining angle at the storage position is smaller than the reference angle, the reclining angle setting operation and the seat outward rotation operation are performed in parallel, so that the operation time in this case can be reduced.

Further, in the above embodiment, the electronic control unit 40 moves the seat back 35 of the seat 30 in the projecting position to the door opening B only by moving the knob of the rotary projecting storage switch 45 to the storage side by the user. Inclining the seat back so as not to hinder the passage of the seat, retracting the seat 30 at the protruding position into the vehicle body from the door opening B, and retracting the seat 30 to the front and at the same time to the storage position. The inward rotation operation of the seat is automatically executed in a predetermined sequence, and the handicapped person or the like seated at the protruding position is moved to the storage position without the head or the like interfering with the door opening. Convenience in the case where a disabled person or the like sitting on the vehicle 30 gets into the storage position is also greatly improved. In this case, in the above-described embodiment, the electronic control device 40 also performs the reclining angle setting operation for setting the seat back 35 to the reclining angle suitable for the rotation of the seat 30 in a predetermined sequence, so that the space in the vehicle body is small. Even in this case, there is no problem in executing the sheet inward rotation operation.

In the above embodiment, the electronic control unit 4
0 indicates that the sheet inward rotation operation is performed after the completion of the sheet retraction operation is confirmed by the last retreat position detection switch 46 of the moving member 25, so that the sheet inward rotation operation is performed before the sheet 30 is completely retracted. Therefore, there is no possibility that interference will occur in unexpected parts.

Further, in the above-described embodiment, the electronic control unit 40 operates the passenger seat door courtesy switch 49 to control the seat 3.
Since the respective operations described above are executed only when it is detected that the door corresponding to 0 is open, the vehicle rotating seat operates with the door not opened and the seat 30 is opened. However, there is no problem with collision with the door.

In the above embodiment, the case where the present invention is applied to a passenger seat of a passenger car has been described. However, the present invention is not limited to this, and can be applied to a rear seat of a passenger car or the like.

[0029]

According to the present invention, when the seat in the storage position is set to the projecting position protruding out of the door opening, the control device performs the seat outward rotation operation, the seat protruding operation, and the seat back tilting operation. Are executed sequentially, so that the user can easily get in and out of the disabled person sitting in the storage position without the risk that the head or the like interferes with the door opening with only one operation for operating the control device. The vehicle can be moved to the protruding position, and the convenience of use of the vehicle rotating seat can be improved.

According to the seat back returning operation for returning the reclining angle of the seat back to a value suitable for getting on and off after the seat protruding operation,
