Description

  The present disclosure relates to a technique for adjusting the state of two or more seats arranged in the front-rear direction in a vehicle in which a plurality of rows of seats are arranged in the front-rear direction.

  In recent years, a three-row seat type vehicle type in which three rows of seats are arranged in the front-rear direction has become widespread centering on relatively large-sized passenger cars such as minivans and SUVs (see, for example, Patent Document 1).

  Various types of three-row seat type passenger cars are provided that can be arranged in various positions and states for the purpose of effective use of the passenger compartment and improvement of getting on and off the third-row seat. Yes.

  For example, in order to secure a space for loading a long or large baggage, the seat back of the second row seat and the seat back of the third row seat are pushed forward to the maximum or close to it. Passenger cars configured to be able to do so are known. For example, in order to improve the ease of getting on and off from the rear door to the third row seat, the second row seat can be tumbled to greatly increase the longitudinal distance between the second row seat and the third row seat. A passenger car constructed as described above is also known.

  However, for example, when flattening the seat back of the second row seat forward, depending on the position of the first row seat, the first row seat becomes obstructive and the seat back of the second row seat is sufficiently forward. A state that can not be defeated can occur. In that case, the user first needs to move the first row seat forward, for example, to secure a sufficient space in front of the second row seat, and then defeat the seat back of the second row seat, It is not convenient for the user.

  The same applies when the second row sheet is tumbled, and depending on the position of the first row sheet, the first row sheet may be in the way and the second row sheet cannot be completely tumbled. obtain. In that case, in order to completely tumble the second row sheet, the user moves the first row sheet forward, for example, even if the second row sheet becomes tumbled. It is necessary not to hit the first row sheet, which is inconvenient for the user.

The above-described problem is a problem that can similarly occur in any two seats arranged continuously in the front-rear direction in a vehicle in which a plurality of seats are arranged in the front-rear direction.
An object of the present disclosure is to improve the convenience of a user when performing adjustment including tilting a seat back forward with respect to a specific seat in a vehicle having at least two rows of seats.

One aspect of the present disclosure is mounted on a vehicle in which a plurality of seats are arranged in the front-rear direction, and the state of at least a specific first seat and the second seat immediately before the first seat among the plurality of seats. It is a vehicle seat adjusting device for adjusting. The vehicle seat adjustment device includes a first drive unit, a second drive unit, an operation unit operated by a user, and a control unit that controls operations of the first drive unit and the second drive unit.

  The first drive unit is configured to be capable of rotating at least the seat back of the first seat relative to the seat cushion of the first seat with respect to the first seat. The second drive unit rotates at least the second seat relative to the second seat relative to the second seat cushion and moves the second seat in the front-rear direction. It is configured to be able to do one.

  The control unit executes the first sheet storing process and the second sheet saving process when the operation unit is operated. The first sheet storing process is a process of moving the first sheet to a specific storing state by operating the first driving unit and rotating at least the seat back of the first sheet forward with respect to the first sheet. It is. In the second sheet retracting process, the second driving unit is operated to rotate the seat back of the second sheet forward relative to the second sheet and / or move the second sheet forward ( Hereinafter, this process is also referred to as “evacuation operation”.

  According to the vehicle seat adjustment device having such a configuration, when the operation unit is operated, the seat back of the first seat is rotated forward by the first seat storing process, and the first seat is in a specific stored state. However, in addition to the first sheet storing process, the second sheet retracting process is also performed, and the second sheet existing in front of the first sheet is retracted.

  Thereby, it can suppress that a 1st sheet | seat contacts the 2nd sheet | seat of the front in the process in which a 1st sheet | seat is made into a specific storing state. Therefore, according to the vehicle seat adjustment device having the above-described configuration, in a vehicle having at least two rows of seats, the user-friendliness when performing adjustment including tilting the seat back forward with respect to a specific seat is performed. Can be improved.

  The control unit may be configured to execute a contact possibility determination process when the operation unit is operated. The contact possibility determination process is a process for determining whether or not the state of the second sheet is in a contactable state such that the first sheet contacts the second sheet when the first sheet storing process is executed. is there. Then, the control unit may execute the second sheet retracting process when it is determined by the contact possibility determination process that the state of the second sheet is a contactable state.

  According to the vehicle seat adjustment device having such a configuration, the second seat retracting process is performed when the second seat is in the contactable state, and the second seat retracting is performed when the second seat is not in the contactable state. Since the processing is not performed, useless execution of the second sheet retracting process can be suppressed.

  Further, the specific storage state with respect to the first seat may be a state in which the seat back of the first seat is rotated and tilted to a predetermined storage position in the forward rotation direction. In this case, the control unit may execute the second sheet return process at a predetermined timing after the execution of the second sheet retracting process. In the second sheet return process, at least one of operating the second driving unit to rotate the seat back of the second sheet backward relative to the second sheet and moving the second sheet backward ( Hereinafter, the second sheet is moved to a return state (for example, a state before execution of the second sheet retracting process) by performing a “return operation”.

According to the vehicle seat adjustment device configured as described above, the second seat is temporarily retracted in order to place the first seat in a specific retracted state, but the predetermined seating timing (for example, the transition to the return state is performed). The second sheet is returned at a timing when the rotation of the seat back of the first sheet is advanced to a state where there is no possibility of the first sheet coming into contact.

Therefore, by appropriately setting the return state, the second sheet can be effectively used even after the first sheet is shifted to the specific storage state.
Further, the control unit may perform the second sheet withdrawal process and the second sheet return process as follows. That is, in the second sheet retracting process, the second sheet is not moved forward, and the seat back of the second sheet is rotated forward. In the second sheet return process, the second sheet is not moved backward, but the seat back of the second sheet is rotated backward.

  When the first sheet storage process is a process of rotating the seat back of the first sheet to a predetermined storage position in the forward rotation direction, the second sheet itself is moved forward as the second sheet retracting operation. There is a high possibility that the object can be sufficiently achieved even if only the seat back is rotated forward without being moved. Therefore, when the first sheet storing process has the above processing contents, the second sheet returning process is performed by preventing the second sheet itself from moving backward in the second sheet returning process. It can be executed efficiently while suppressing the load.

  Further, the vehicle seat adjustment device having the above-described configuration configured to execute the second seat return process may further include a second operation unit. The second operation unit is provided separately from the first operation unit with the aforementioned operation unit as the first operation unit, and is operated by the user.

  The control unit executes the first sheet storing process, the second sheet retracting process, and the second sheet returning process by operating the operation unit, and then the first operation unit is operated when the second operation unit is operated. The sheet restoration process, the second sheet withdrawal process, and the second sheet restoration process may be executed. In the first seat return process, the first drive unit is operated to rotate the seat back of the first seat backward with respect to the first seat, thereby returning the seat back to the return position (for example, the first seat). This is a process of moving to a position before the start of one sheet storing process.

  According to the vehicle seat adjustment device having such a configuration, after the first seat is brought into the specific storage state by the first seat storage process, the seat back of the first seat is removed by operating the second operation unit. It can be easily moved to the return position.

  In addition, when the seat back of the first sheet is moved to the return position, the second sheet is retracted by the second sheet retracting process, and thereafter the returning operation is performed by the second sheet returning process. Therefore, it is possible to suppress the movement of the first sheet to the return position from being inhibited by the second sheet.

On the other hand, the first sheet is provided with a tumble mechanism, and the first driving unit further brings the first sheet brought forward by bringing the first sheet forward and the tumble mechanism is operated. When configured to be able to do so, the control unit may perform the first sheet storing process and the second sheet retracting process as follows. That is, in the first sheet storage process, the first sheet is shifted to the tumble state as the specific storage state. In the second sheet retracting process, the second sheet is caused to both rotate the seat back of the second sheet forward and move the second sheet forward. The tumble mechanism is configured so that the first seat is in a state where the seat back of the first seat is in a forward-turned state (that is, a state where the seat back is rotated to a predetermined storage position in the forward rotation direction). The first seat can be tumbled by rotating the whole forward.

  According to the vehicle seat adjustment device having such a configuration, when the first seat is shifted to the tumble state, the seat back of the second seat is rotated forward and the entire second seat is moved forward. . Therefore, the second sheet can be retreated from the first sheet quickly and efficiently.

  In the configuration in which the first sheet can be tumbled as described above, the control unit causes the first sheet to be brought forward by at least the first sheet storing process in the second sheet retracting process. After the first sheet is moved forward, the second sheet retracting process is continued even after the tumble mechanism is activated by the first drive unit and the transition to the tumble state is started. It may be. With such a configuration, the second sheet can be retracted from the first sheet more reliably.

  Further, when the first seat is configured to be able to return to the original forward state from the tumble state, and the vehicle seat adjusting device is returned from the tumble state to the forward state. You may provide the detection part which detects this. In that case, after the first sheet storing process and the second sheet retracting process are performed, the control unit performs the first sheet returning process when the detecting unit detects that the first sheet is returned to the forward-turned state. The second sheet evacuation process may be executed.

  According to the vehicle seat adjustment device having such a configuration, the first seat can be quickly and efficiently returned to the return position and the second seat to the return state after the first seat has been tumbled. Can be done automatically.

  Further, the second seat may be a first row of seats from among a plurality of seats of the vehicle, and the first seat may be a second row of seats from among the plurality of seats of the vehicle. According to the vehicle seat adjustment device having such a configuration, when the seat back of the second row of seats is tilted forward or tumbled, the first row of seats automatically retracts forward, The user can efficiently arrange the second row of sheets.

The third seat 13 also includes a seat cushion 13a and a seat back 13b, and a headrest 13c is attached to the upper portion of the seat back 13b.

  The front seat 11 is provided with a front reclining motor 6 and a slide motor 8. A seat back (hereinafter referred to as “front seat back”) 11 b of the front seat 11 is configured to be rotatable in the direction of the broken line arrow in the figure with the front reclining motor 6 as a drive source and the rotation shaft 51 as an axis. .

  In the present specification, “front” and “rear” are defined as indicated by broken-line arrows in FIG. In other words, the rotation of the seat back “forward” means that the seat back is tilted forward to the front side of the vehicle (thus, the surface of the seat back approaches the surface of the seat cushion). Conversely, the rotation of the seat back to the “rear” means that the seat back is tilted to the rear side of the vehicle (thus the surface of the seat back moves away from the surface of the seat cushion and the seat back approaches the rear seat). Means).

  Further, the front seat 11 is configured to be slidable in the front-rear direction using the slide motor 8 as a drive source. Specifically, the front seat 11 is installed on the floor of the vehicle 1 via a slider device (not shown).

  Locking of the lock member with the striker is performed mechanically by pressing the lock member against the striker. On the other hand, the locked state of the lock member of the floor lock 17 and the striker is released by operating the floor lock release motor 18.

  In a state where the lock member of the floor lock 17 is locked by the striker and the second seat 12 is fixed to the floor, the second seat 12 cannot be tumbled. On the other hand, when the fixing to the floor by the floor lock 17 is released, the second seat 12 can be rotated forward by the tumble mechanism 16 to be in a tumble state. The tumble mechanism 16 is configured to apply an urging force in a direction to shift the second seat 12 to the tumble state by an elastic member (for example, a coil spring). Therefore, when the floor lock release motor 18 is actuated and the locked state between the floor lock 17 and the floor striker is released, the second seat 12 is rotated in the tumble direction by the aforementioned urging force of the tumble mechanism 16. Transition to the tumble state.

  A floor lock limit switch 47 is provided near the floor lock 17. The floor lock limit switch 47 is turned on when the floor lock 17 is locked to the floor (that is, the lock member of the floor lock 17 is locked to the striker), and the floor lock 17 is locked with the floor. It is turned off in a released state (that is, a state where the lock member of the floor lock 17 is detached from the striker).

  The second seat 12 is provided with a forward limit switch 46. The forward limit switch 46 is turned on when the second seat back 12b is most forwardly rotated (a state where the second seatback 12b reaches the most forward tilt position described later), and is turned off in other states.

  A third reclining motor 31 is provided on the third seat 13. A seat back (hereinafter referred to as “third seat back”) 13b of the third seat 13 is configured to be rotatable in the direction of the broken line arrow in the drawing with the third reclining motor 31 as a drive source and the rotation shaft 53 as an axis. .

  The vehicle 1 is provided with two doors (a front door and a rear door) for getting on and off in the front-rear direction on both side surfaces of the vehicle body. You can sit on the front seat 11 by opening the front door, and you can sit on the second seat 12 by opening the rear door. Further, by opening the rear door and tilting the second seat back 12b forward, it is possible to enter the rear portion of the second seat 12 from the rear door and sit on the third seat 13. In the present embodiment, the second sheet 12 can be tumbled as described above. Therefore, by making the second seat 12 in the tumble state when the passenger gets on and off the third seat 13, a wider space for getting on and off can be secured.

  In addition, a luggage compartment door for loading and unloading luggage is provided on the rear side of the vehicle 1. By opening the luggage compartment door, luggage can be taken in and out from the rear side of the vehicle 1 into the cabin. it can.

In addition, the vehicle 1 includes a boarding / alighting mode transition switch 23, a boarding / alighting mode release switch 24, a luggage room mode transition switch 33, and a luggage room mode release as switches operated by a user such as a driver or another passenger A switch 34 is provided.

  Here, the range in which the seatbacks 11b, 12b, and 13b can be rotated will be specifically described with reference to FIG. 2 by taking the second seatback 12b as an example. As shown in FIG. 2, the second seat back 12b is rotatable within a rotatable range from the most forward tilt position to the last tilt position. The foremost tilt position is a position when the second seat back 12b is tilted most forward, and the last tilt position is a position when the second seat back 12b is tilted most rearward.

  Here, the angle of the second seat back 12b when the horizontal plane Lf parallel to the floor of the vehicle 1 is used as a reference is referred to as an inclination angle. The state in which the second seat back 12b is positioned at the foremost tilt position has the smallest tilt angle. When the second seat back 12b is rotated backward from the most forward tilt position, the tilt angle increases, and at the final tilt position, the tilt angle becomes the largest.

  The inclination angle of the second seat back 12b can be electrically changed by the second reclining motor 21 as described above. In particular, in a seating area between a predetermined reference position and the last tilt position within the pivotable range, the user can operate the reclining switch (not shown) to change the tilt angle of the second seat back 12b continuously or It can be changed in stages. The reference position of the present embodiment is an upright position, that is, a position where the second seat back 12b is erected vertically with respect to the horizontal plane Lf.

  When the second seat back 12b is tilted forward (ie, stored) to the most forward tilt position, the second seat 12 is in a state where the back surface of the second seat back 12b is nearly parallel to the horizontal plane Lf (hereinafter referred to as “table state”). The back surface of the second seat back 12b can be used as a table.

  The pivotable range and reference position of the front seat back 11b and the third seat back 13b are basically the same as in the case of the second seat back 12b shown in FIG. That is, the front seat back 11 b can also be rotated within a rotatable range from the most forward tilt position to the last tilt position, and the tilt angle can be electrically changed by the front reclining motor 6. The third seat back 13 b can also be rotated within a rotatable range from the most forward tilt position to the last tilt position, and the tilt angle can be electrically changed by the third reclining motor 31.

As for the front seat back 11b and the third seat back 13b, similarly to the second seat back 12b, the user can change the inclination angle continuously or stepwise by operating a reclining switch (not shown) in the seating area. The structure which can do is also possible. Further, the front seat 11 may be configured such that the user can operate the slide motor 8 to change the position in the front-rear direction continuously or stepwise by operating a slide switch (not shown). Good. In addition, the respective seat backs 11b, 12b, 13b may have the same or different inclination angles at the foremost inclination position. The same applies to the inclination angle of the last inclination position. Further, although the reference position is the upright position in the present embodiment, this is merely an example, and where the reference position is set may be appropriately determined. Further, the inclination angles of the reference positions may be the same or different for the sheets 11, 12, and 13, respectively.

(2) Description of Seat Adjustment Device Next, the seat adjustment device 2 provided in the vehicle 1 for adjusting the position and state of each seat 11, 12, 13 will be described with reference to FIG.

The seat adjusting device 2 includes the five motors described above, that is, the front reclining motor 6, the slide motor 8, the second reclining motor 21, the floor lock release motor 18, and the third reclining motor 31.

  The four operation switches 23, 24, 33, and 34 are push button switches, for example, and are turned on while being operated by the user, and are turned off when the operation by the user is released. However, it is not essential to be a push button switch, and other types of switches may be used.

  In the present embodiment, the five motors 6, 8, 18, 21, and 31 are, for example, brushed DC motors. However, it is not essential to be a DC motor with a brush, and other types of motors (for example, a brushless motor, a stepping motor, etc.) may be used.

  The electronic control device 40 includes a control unit 41, an input circuit 42, and a drive circuit 43. The input circuit 42 is connected to the above-described switches and other switches (not shown), and signals from these switches are input. The input circuit 42 outputs the input signal from each switch to the control unit 41 as it is or after appropriate conversion (for example, level conversion, AD conversion, impedance conversion, etc.).

  The control unit 41 is configured around a known microcomputer having a CPU, a memory, and the like. Various functions of the control unit 41 are realized by the CPU executing a program stored in the memory. The realization of various functions by the control unit 41 is not limited to software, and some or all of the various functions may be realized using hardware that combines a logic circuit, an analog circuit, and the like.

  The control unit 41 determines an operation state of each switch based on a signal input from each switch via the input circuit 42. Then, when any one of the switches is operated, the control unit 41 corresponds to the operated switch among the above-described five motors 6, 8, 18, 21, 31 and other motors (not shown). A drive signal for driving one or a plurality of motors is output to the drive circuit 43.

  The drive circuit 43 is configured to be able to individually drive each motor in accordance with a drive signal from the control unit 41. The drive circuit 43 is provided with a drive circuit (for example, an H bridge circuit) for driving each motor individually for each motor.

Further, at least the front reclining motor 6, the slide motor 8, the second reclining motor 21, and the third reclining motor 31 among the motors are provided with rotation sensors 7, 9, 22, and 32, respectively. Each of these rotation sensors 7, 9, 22, 32 is connected to a control unit 41 in the electronic control device 40. Each rotation sensor 7, 9, 22, 32 outputs a rotation signal that is a signal indicating the rotation position of the corresponding motor.

  The control unit 41 detects the rotational position of the front reclining motor 6 based on an input signal from the rotation sensor 7 provided in the front reclining motor 6, and the position (inclination) of the front seat back 11b based on the rotational position. Corner). Further, the control unit 41 detects the rotational position of the slide motor 8 based on an input signal from the rotation sensor 9 provided in the slide motor 8, and based on the rotational position, the front / rear position of the front seat 11 is detected. Is detected.

  Moreover, the control part 41 detects the rotation position of the second reclining motor 21 based on the input signal from the rotation sensor 22 provided in the second reclining motor 21, and the position of the second seat back 12b based on the rotation position. (Tilt angle) is detected. Moreover, the control part 41 detects the rotational position of the 3rd reclining motor 31 based on the input signal from the rotation sensor 32 provided in the 3rd reclining motor 31, and the position of the 3rd seat back 13b based on the rotational position. (Tilt angle) is detected.

  As a method for the control unit 41 to detect the position of the front seat 11 in the front-rear direction and the positions (tilt angles) of the seatbacks 11b, 12b, 13b, a method of detecting based on the rotational position of each motor as described above Is just an example. The control unit 41 may detect the position of the front seat 11 in the front-rear direction and the positions (tilt angles) of the seatbacks 11b, 12b, and 13b using other methods. For example, an angle sensor may be provided in each of the seat backs 11b, 12b, and 13b, and the inclination angle of each of the seat backs 11b, 12b, and 13b may be directly detected.

  In the present embodiment, various seat arrangements are realized by controlling the positions and states of the respective sheets 11, 12, and 13 individually or in conjunction with each other by the control unit 41 of the sheet adjusting apparatus 2. As one aspect of the seat arrangement realized by the control unit 41 of the seat adjustment device 2, there are at least a cargo compartment mode and a boarding / alighting mode.

  The cargo compartment mode is a mode mainly intended to allow loading of large or long luggage, and the second seat 12 is brought down by tilting the second seat back 12b and the third seat back 13b to the most forward tilt position. And a mode of generating a large luggage loading space in the front-rear direction as a whole in the upper space of the third seat 13.

  The boarding / exiting mode is a mode for mainly improving the boarding / exiting performance from the rear door to the third seat 13 and is a mode in which a wide space is generated in front of the third seat 13 by setting the second seat 12 in a tumble state.

  The transition to each mode and the cancellation of each mode can be realized by the user performing a switch operation. In other words, the luggage compartment mode transition switch 33 can be turned on to shift to the luggage compartment mode. Moreover, after shifting to the cargo compartment mode, the original standard state can be restored by turning on the cargo compartment mode release switch 34. The standard state means a state in which each of the seat backs 11b, 12b, 13b is located in the seating area.

Moreover, it can transfer to boarding / alighting mode by turning ON the boarding / alighting mode transition switch 23. Moreover, after shifting to the boarding / alighting mode, the original standard state can be restored by turning on the boarding / alighting mode release switch 24.

(3) Cargo Room Mode Transition Process Regarding the cargo room mode transition process for shifting to the cargo room mode, which is executed by the control unit 41 when the cargo room mode transition switch 33 is turned on, FIG. I will explain. The cargo compartment mode transition process may be executed while the cargo compartment mode transition switch 33 is kept on by the user, or after the cargo compartment mode transition switch 33 is turned on, Even if the operation is canceled, it may be executed to the end.

  Here, each of the seats 11, 12, and 13 is in a standard state, and as shown in FIG. 5A, each of the seat backs 11b, 12b, and 13b is at an arbitrary initial position in the seating area. Assume that it is located.

  When the cargo compartment mode transition switch 33 is turned on, the control unit 41 starts the cargo compartment mode transition processing of FIG. 4 and determines whether or not the front seat 11 is present in the second seat passage region in S110. .

  The second seat passing area is a process in which the second seat back 12b rotates from the initial position to the most forward tilt position (including the reverse process), and the second seat back 12b and the headrest 12c exist temporarily or continuously. It is an area. In the process in which the second seat back 12b is rotated forward, the top of the headrest of the second seat 12 moves along a forward inclination locus La indicated by a one-dot chain line in FIGS. 5 (A) and 5 (B).

  Therefore, the forward inclination locus La is a boundary line of the second seat passage area, and when the front seat 11 is present at a part of the rear side of the forward inclination locus La, the front seat 11 passes through the second seat. It exists in the area. On the contrary, when the front seat 11 as a whole exists on the front side of the forward inclination locus La, the front seat 11 does not exist in the second seat passage region.

  In S110, the control unit 41 detects the positions of both the front seat 11 and the second seat 12, and based on the detected positions and the specification information (dimensions and other information) of each of the sheets 11 and 12, the front seat It is determined whether 11 is present in the second sheet passage area. It should be noted that when the seats 11, 12, and 13 are simply referred to as “position”, both the position in the front-rear direction and the inclination angle of the seat back are meant.

  If the front seat 11 does not exist in the second seat passage area in S110, the process proceeds to S170. In S170, by driving the second reclining motor 21 and the third reclining motor 31, the second seat back 12b starts to rotate forward, and the third seat back 13b also starts to rotate forward. It is not essential that the second seat back 12b and the third seat back 13b start to rotate at the same time, and the rotation may be sequentially started one by one with a time difference.

By the process of S170, the second seat back 12b and the third seat back 13b are gradually rotated forward as shown in order in FIGS. 5 (A) to 5 (D).
In S180, the second seat back 12b and the third seat back 13b wait for each to reach the most forward tilt position, and when reaching the most forward tilt position, the rotation is stopped by stopping the corresponding reclining motor. As a result, finally, as shown in FIG. 5D, the second seat 12 and the third seat 13 are both forwardly tilted to the most forward tilt position (that is, in the table state).

  The determination as to whether or not the foremost tilt position has been reached is made based on the position (tilt angle) of the seat back detected based on the rotation signal from the rotation sensor. For the second seat 12, a forward limit switch 46 is provided. Therefore, in the present embodiment, it is determined that the second seat back 12b has reached the most forward tilt position when the forward limit switch 46 is turned on.

  If the front seat 11 is present in the second seat passage area in S110, the process proceeds to S120. In S120, as in S170, the second seat back 12b is started to rotate forward, and the third seat back 13b is also started to rotate forward.

  In S130, the front reclining motor 6 is driven to rotate the front seat back 11b forward. Then, when the front seat back 11b reaches the retracted position, the rotation is stopped. The retracted position is an arbitrary position on the front side of the second seat passage region (that is, on the front side of the forward tilt locus La). The retreat position is set by the control unit 41 by a predetermined calculation based on the second sheet passing area. FIG. 5B shows a state immediately after the front seat back 11b is rotated to the retracted position and stopped by the process of S130.

  A certain time difference may be provided between S120 and S130, and the front seat back 11b may be started to rotate after the second seat back 12b and the third seat back 13b start to rotate and after a certain time has elapsed. Further, the front seat back 11b may be started to rotate first before the process of S120. In that case, after starting the rotation of the front seat back 11b, the second seat back 12b and the third seat back 13b may be started to rotate after a predetermined time has elapsed.

  In S140, it is determined whether or not the second seat back 12b is moved forward to the front return possible range. The front returnable range is a range in which the front seat 11 does not come into contact with the second seat 12 even if the front seatback 11b is rotated backward from the current retracted position to reach the return position. .

  When the forward rotation of the second seat back 12b proceeds and enters the front return possible range, the backward rotation of the front seat back 11b is started in S150. FIG. 5C shows a state immediately after the forward rotation of the second seat back 12b has advanced and has already entered the front returnable range, and thereby the backward rotation of the front seat back 11b is started. Yes.

  In S160, when the front seat back 11b is rotated backward and reaches the return position, the rotation is stopped by stopping the front reclining motor 6. Further, as with S180, the second seat back 12b and the third seat back 13b are each waiting for reaching the most forward tilt position, and when reaching the most forward tilt position, the rotation is stopped by stopping the corresponding reclining motor. Let

  The return position of the front seat back 11b may be determined as appropriate. For example, it may be the position of the front seat back 11b when the cargo compartment mode transition switch 33 is turned on and the cargo compartment mode transition processing is started. A preset position (for example, a reference position) may be used.

(4) Cargo Room Mode Canceling Process Next, after the cargo room mode is changed to the cargo mode (that is, after being brought into the state shown in FIG. 5D), the cargo room mode releasing switch 34 is turned on. In this case, the loading chamber mode cancellation processing for canceling the loading chamber mode and returning to the standard state performed by the control unit 41 will be described with reference to FIGS. 6 and 7. It should be noted that the cargo compartment mode release process may be executed while the cargo compartment mode release switch 34 is kept on by the user, or after the cargo compartment mode release switch 34 is turned on, Even if the operation is canceled, it may be executed to the end.

  When the cargo compartment mode release switch 34 is turned on in the cargo compartment mode as shown in FIG. 7A, the control unit 41 executes the cargo compartment mode release processing of FIG. When the control unit 41 starts the cargo compartment mode release process of FIG. 6, in S210, the control unit 41 determines whether or not the front seat 11 is present in the second seat passage region. This process is basically the same as S110 in FIG.

  If it is determined in S210 that the front seat 11 does not exist in the second seat passage area, the process proceeds to S270. In S270, by driving the second reclining motor 21 and the third reclining motor 31, the second seat back 12b starts to rotate backward, and the third seat back 13b also starts to rotate backward. It is not essential that the second seat back 12b and the third seat back 13b start to rotate at the same time, and the rotation may be sequentially started one by one with a time difference.

By the process of S270, the second seat back 12b and the third seat back 13b are gradually rotated rearward as shown in FIGS. 7A to 7D sequentially.
In S280, each of the second seat back 12b and the third seat back 13b waits to reach the return position, and when it reaches the return position, the rotation is stopped by stopping the corresponding reclining motor. As a result, finally, as shown in FIG. 7D, both the second seat 12 and the third seat 13 are tilted backward to the return position, and the cargo compartment mode is released.

  Note that the return positions of the second seat back 12b and the third seat back 13b may be individually determined as appropriate, for example, the initial positions when the cargo compartment mode transition switch 33 is turned on and the cargo compartment mode transition processing is started. Alternatively, a preset position (for example, a reference position) may be used.

  If the front seat 11 is present in the second seat passage area in S210, the process proceeds to S220. In S220, as in S270, the second seat back 12b is started to rotate backward, and the third seat back 13b is also started to rotate backward.

  In S230, the front reclining motor 6 is driven to rotate the front seat back 11b forward to the retracted position and stop it. FIG. 7B shows a state immediately after the front seat back 11b is rotated to the retracted position and stopped by the process of S230.

A certain time difference may be provided between S220 and S230, and the front seat back 11b may be started to rotate after the second seat back 12b and the third seat back 13b start to rotate and after a certain time has elapsed. Further, the front seat back 11b may be started to rotate first before the process of S220. In that case, after starting the rotation of the front seat back 11b, the second seat back 12b and the third seat back 13b may be started to rotate after a predetermined time has elapsed.

  In S240, it is determined whether or not the second seat back 12b has been rotated backward to be tilted back to the front return possible range. If the second seat back 12b is pivoted rearward and enters the front returnable range, in S250, the rear pivoting of the front seat back 11b is started. FIG. 7 (C) shows a state immediately after the second seat back 12b has been pivoted rearward and has already entered the front recoverable range, thereby starting the rear pivoting of the front seat back 11b. Yes.

  In S260, the rotation of the front seat back 11b is stopped when the rearward rotation advances and reaches the return position. Further, as with S280, the second seat back 12b and the third seat back 13b are each waited for reaching the return position and stopped when they reach the return position.

(5) Boarding / alighting mode transition process Next, a boarding / alighting mode transition process for shifting to the boarding / alighting mode executed by the control unit 41 when the boarding / alighting mode transition switch 23 is turned on will be described with reference to FIGS. 8 and 9. explain. The boarding / alighting mode transition process may be executed while the boarding / alighting mode transition switch 23 is continuously turned on by the user, or the on-operation is released after the boarding / alighting mode transition switch 23 is turned on. Or may be executed to the end.

  Here, both the front seat 11 and the second seat 12 are in the standard state, and as shown in FIG. 9A, the respective seat backs 11b and 12b are located at arbitrary initial positions in the seating area. Assuming that

  When the boarding / alighting mode transition switch 23 is turned on to start the boarding / alighting mode transition process, the control unit 41 drives the second reclining motor 21 to rotate the second seat back 12b forward in S310. Let it begin.

  In S320, the front seat 11 is started to rotate forward by driving the front reclining motor 6, and the slide movement of the front seat 11 is further started by driving the slide motor 8. To start.

  Note that the forward rotation of the front seat back 11b and the forward slide movement of the front seat 11 may be started at the same timing, or may be started sequentially with a time difference. Further, the order and timing of the processes of S310 and S320 may be determined as appropriate. For example, the forward rotation of the second seat back 12b may be started in S310, and the process of S320 may be performed after a predetermined time has elapsed. Alternatively, the driving of the front seat 11 may be started in advance of the process of S320, and the process of S310 may be performed after a predetermined time has elapsed since the start.

  In S330, it is determined whether or not the second seat back 12b has reached the foremost tilt position. If it has not reached the foremost tilt position, it is determined in S340 whether or not the front seat 11 is in the retracted state. The retreat completion state is a state where the front seat 11 as a whole does not hit the second seat 12 even if the second seat 12 is in the tumble state.

If the front seat 11 is not yet in the retracted state, the process returns to S330, and the front seat back 11b is rotated forward and the front seat 11 is slid forward. If the front seat 11 is already in the retracted state, in S350, the forward rotation of the front seat back 11b and the sliding movement of the front seat 11 are stopped, and the process returns to S330.

  In S330, if the second seat back 12b has reached the foremost tilt position, the process proceeds to S360. FIG. 9B shows a state immediately after the second seat back 12b has reached the foremost tilt position.

  After progressing to a state as shown in FIG. 9B, in S360, the floor lock is released. That is, the floor lock is released by driving the floor lock release motor 18. By releasing the floor lock, the urging force of the tumble mechanism 16 starts the transition of the second seat 12 to the tumble state, that is, the forward rotation of the tumble mechanism 16 about the rotation shaft 16a. Then, as shown in FIGS. 9B to 9D, the second seat 12 rotates forward about the rotation shaft 16a, and finally the tumble state shown in FIG. Stop.

  In S370, it is determined whether or not the driving of the front seat 11 has already been stopped (that is, whether or not the processing in S350 has already been performed). If the driving of the front seat 11 has already been stopped, the entry / exit mode transition processing is terminated. If the driving of the front seat 11 has not been stopped, the process proceeds to S380.

  In S380, as in S340, it is determined whether or not the front seat 11 is in the retracted state. If the front seat 11 is not yet in the evacuation completion state, it waits for the evacuation completion state, and if it is in the evacuation completion state, the driving of the front seat 11 is stopped in S390.

FIG. 9D shows a state in which the transition to the getting-on / off mode is completed when the front seat 11 is in the retracted completion state and the second seat 12 is in the tumble state.
(6) Entry / exit mode release processing Next, after the second mode 12 is returned to the table state after being changed to the entry / exit mode by the entry / exit mode transition processing (that is, after the state shown in FIG. 9D), the control is performed. The getting-on / off mode canceling process executed by the unit 41 will be described with reference to FIG.

  As shown in FIG. 9D, when returning to the standard state from the state in which the boarding / alighting mode is set, the second seat 12 is normally manually shifted to the table state by the user. When the second seat 12 is tilted backward by the user to enter the table state, the floor lock is locked and the floor lock limit switch 47 is turned on.

  When the floor lock limit switch 47 is turned on due to the return from the tumble state to the table state, the control unit 41 executes the entry / exit mode release processing of FIG. When starting the boarding / alighting mode canceling process of FIG. 10, the control unit 41 rotates the second seat back 12b rearward and returns it to the return position in S410. In step S420, the front seat 11 is returned to the return position by rotating the front seat back 11b rearward, and is returned to the return position by sliding the front seat 11 backward.

  The return position in the front-rear direction may be determined as appropriate, and may be, for example, the position in the front-rear direction immediately before the entry / exit mode transition process is started, or may be a predetermined reference position set in advance in the front-rear direction. Good.

Moreover, the boarding / alighting mode release process may be executed, for example, when the boarding / alighting mode release switch 24 is turned on after the floor lock limit switch 47 is turned on from the tumble state to the table state. In addition, when the function of returning from the tumble state to the table state is electrically operated, when the getting-on / off mode release switch 24 is turned on in the getting-on / off mode state, the tumble state is returned to the seating area via the table state. The operation may be performed electrically.

(7) Effects of Embodiments According to the embodiments described above, the following effects can be obtained.
That is, when the luggage compartment mode transition switch 33 is turned on and the second seat back 12b is rotated to the forward tilt position, the front seat back 11b is also rotated forward. Thereby, it is possible to suppress the second seat 12 from coming into contact with the front seat 11 in the process in which the second seat back 12b is tilted to the foremost tilt position. The user-friendliness for shifting to the cargo compartment mode can be improved.

  Further, in the present embodiment, when the cargo compartment mode transition switch 33 is turned on, the front seat back 11b is not unconditionally rotated forward, but the front seat 11 exists in the second seat passage region. When the vehicle is on, the front seat back 11b is rotated forward (see S110 in FIG. 4). For this reason, when the front seat 11 is not present in the second seat passage region, the front seat back 11b is not rotated, so that unnecessary rotation of the front seat back 11b is suppressed.

  Further, when the load mode switching switch 33 is turned on and the front seat back 11b is rotated forward, when the rotation of the second seat back 12b advances and reaches the front return possible range, the front seat back 11b is It is rotated backward again and returned to the return position. Therefore, by appropriately setting the return position, the front seat 11 can be used effectively even after the second seat back 12b is moved forward and the transition to the cargo compartment mode is completed.

  In addition, the luggage compartment mode can be easily released by turning on the luggage compartment mode release switch 34 after the transition to the luggage compartment mode. Also in this case, the front seat back 11b is temporarily rotated forward, and contact with the second seat 12 is avoided.

  When the getting-on / off mode transition switch 23 is turned on and the second seat 12 is transitioned to the tumble state, the front seat back 11b is rotated forward and the entire front seat 11 is moved forward. Therefore, the front seat 11 can be retracted from the second seat 12 quickly and efficiently.

  In addition, by manually returning from the tumble state to the table state after shifting to the getting on / off mode, the second seat 12 and the front seat 11 can be quickly and efficiently returned to the predetermined positions, respectively.

(8) Correspondence Relationship with Claims Here, the correspondence relationship between the words of the present embodiment and the words of the claims will be described.
The second seat 12 corresponds to the first seat, and the front seat 11 corresponds to the second seat. The second reclining motor 21 corresponds to a first drive unit, and the front reclining motor 6 corresponds to a second drive unit. The boarding / alighting mode transition switch 23 and the cargo compartment mode transition switch 33 correspond to a first operation part, and the boarding / alighting mode release switch 24 and the cargo room mode release switch 34 correspond to a second operation part. The table state of the second seat 12 corresponds to a specific storage state, and the most forward tilt position, which is the position in the table state, corresponds to the storage position. The state in which the front seat 11 is present in the second seat passage region corresponds to a contactable state. The timing at which an affirmative determination is made in S140 of the cargo compartment mode transition process (FIG. 4) corresponds to the return timing.

[Other Embodiments]
As mentioned above, although embodiment of this indication was described, this indication is not limited to the above-mentioned embodiment, and can carry out various modifications.

  (1) At the time of shifting to the getting-on / off mode, it is not essential to both rotate the front seat back 11b forward and slide the entire front seat 11 forward. For example, the front seat back 11b may not be rotated forward, and conversely, the entire front seat 11 may not be slid forward.

  (2) As the boarding / alighting mode transition process for transitioning to the boarding / alighting mode, the above embodiment has been described with reference to FIG. 8, but an example of another boarding / alighting mode transition process different from that in FIG. It explains using.

  First, regarding the configuration of the second seat 12 that is a precondition for enabling execution of the entry / exit mode transition processing of FIG. 11, a configuration different from the above embodiment will be described. In addition to the configuration of the above-described embodiment, the second seat 12 can further freely rotate the second seat back 12b with respect to the seat cushion 12a by releasing the connection state between the second seat back 12b and the second reclining motor 21. It is configured to be in a state.

  The rotational driving force of the second reclining motor 21 is transmitted to the second seat back 12b via a driving force transmission mechanism (not shown). Normally, the second seat back 12b is mechanically coupled to the second reclining motor 21 via a driving force transmission mechanism, and the second seat back 12b rotates when the second reclining motor 21 rotates. The second seat 12 is configured to be able to release the mechanical connection between the second reclining motor 21 and the second seat back 12b.

  In the following description, when the second seat back 12b is referred to as “locked” or “locked state”, it means that the second reclining motor 21 and the second seat back 12b are mechanically connected. The term “unlocked” or “unlocked state” means a state in which the mechanical connection between the second reclining motor 21 and the second seat back 12b is released.

  When the second seat back 12b is unlocked, even if the second reclining motor 21 rotates, the second seat back 12b does not rotate, and the second seat back 12b can freely rotate with respect to the seat cushion 12a. Become.

  The second seat back 12b is locked and unlocked by a lock mechanism (not shown). The lock mechanism includes an actuator for bringing the second seat back 12b into an unlocked state, and the second seat back 12b is unlocked when the actuator is driven and controlled by the control unit 41. The locking mechanism also has a function of returning the second seat back 12b from the unlocked state to the locked state.

  Further, the second seat back 12b is biased in a direction to rotate forward by an elastic member (not shown). Therefore, when the second seat back 12b is brought into the unlocked state, the second seat back 12b can be rotated forward by the above-described urging force and reach the most forward tilt position.

  In addition, the vehicle 1 is used as a switch operated by the user to shift to the getting-on / off mode so that the second seat back 12b is unlocked and moved forward by the urging force to shift to the tumble state. Switch (hereinafter referred to as manual entry / exit mode transition switch).

  The boarding / alighting mode transition process executed by turning on the manual boarding / alighting mode transition switch will be described with reference to FIG. When the manual entry / exit mode transition switch is turned on to start the entry / exit mode transition process of FIG. 11, the control unit 41 determines whether the front seat 11 is in the retracted completion state in S410.

  If the front seat 11 is already in the retracted state, the process proceeds to S430. If the front seat 11 is not yet in the evacuation completion state, the front seat is placed in the evacuation completion state in S420. Specifically, with respect to the front seat 11, the front seat 11 is brought into a retracted completion state by performing at least one of forward rotation of the front seat back 11 b and sliding movement of the front seat 11 forward. If the front seat 11 is in the retracted state, the process proceeds to S430.

  In S430, the second seat back 12b is unlocked and unlocked. Specifically, the lock is released by driving the actuator of the lock mechanism described above.

  When the lock of the second seat back 12b is released in S430, the second seat back 12b is rotated forward by the urging force of the elastic member (not shown) and reaches the foremost tilt position as described above. At this time, the arrival at the foremost tilt position may be manually assisted.

  In S440, it is determined whether or not the second seat back 12b has reached the foremost tilt position. If it has not reached the foremost tilt position, the determination is repeated until it reaches, and if it reaches, the process proceeds to S450. In S450, the floor lock is released by driving the floor lock release motor 18. When the floor lock is released, the second seat 12 shifts to the tumble state.

  When the manual entry / exit mode transition switch is turned on as described above, the second seat back 12b can be electrically returned to the seating area again by the entry / exit mode release process of FIG. The second seat back 12b may be locked again at an appropriate timing. For example, when the transition from the table state to the tumble state is started, the lock mechanism may be operated to enter the lock state. Further, for example, the lock state may be set when the entry / exit mode release processing of FIG. 10 is started (or just before the start) by manually returning from the tumble state to the table state. By doing so, even when the manual entry / exit mode transition switch is turned on to switch to the entry / exit mode, the second seat back can be electrically driven by returning the second seat 12 from the tumble state to the table state as in the above embodiment. 12b can be returned to the seating area.

  (3) In the entry / exit mode transition process of FIG. 8, after starting the process, it is first determined whether or not the front seat 11 is in the retracted completion state. If the front seat 11 is already in the retracted completion state, the front seat 11 is not moved and is The sheet 12 may be shifted to the tumble state.

(4) When shifting to the cargo compartment mode, in addition to rotating the front seat back 11b forward, the entire front seat 11 may be slid forward.
(5) In the above embodiment, one electronic control unit 40 is configured to control each of the sheets 11, 12, and 13. However, such a hardware configuration is merely an example.

  For example, an electronic control device is provided for each of the front seat 11, the second seat 12, and the third seat 13. The electronic control device for the front seat 11 controls the operation of the front seat 11, and the electronic for the second seat 12. The control device may control the second seat 12 and the electronic control device for the third seat 13 may control the third seat 13. As a result, each electronic control device is connected to be able to perform data communication via a wired or wireless data communication network, and the control information on the own device side is transmitted to the other side to share information between the electronic control devices. Each process (FIGS. 4, 6, 8, and 10) described in the above embodiments may be realized.

  (6) As the operation switches for shifting and canceling the getting on / off mode, the above embodiment has shown an example in which the getting on / off mode shifting switch 23 and the getting on / off mode canceling switch 24 are individually provided. The functions of both switches may be realized by a switch. For example, after shifting to the boarding / alighting mode by turning on the switch, the boarding / alighting mode may be canceled when the same switch is turned on again in the same state in the state of shifting to the boarding / alighting mode. The same applies to the operation switches for shifting and releasing the cargo compartment mode.

  (7) In addition, the functions of one component in the above embodiment may be distributed as a plurality of components, or the functions of a plurality of components may be integrated into one component. Further, at least a part of the configuration of the above embodiment may be replaced with a known configuration having the same function. Moreover, you may abbreviate | omit a part of structure of the said embodiment. In addition, at least a part of the configuration of the above embodiment may be added to or replaced with the configuration of the other embodiment. In addition, all the aspects included in the technical idea specified only by the wording described in the claim are embodiment of this invention.
