That is, according to this configuration, the front seat can be released by simply sliding the rear seat forward and connecting the rear seat to the front seat.

JP 2006-327506 A

  However, even with the above technique, there are cases where it takes time and effort for the operator to change the arrangement of the sheets. For example, in the case where the sheets are rearranged so that the second row sheet and the third row sheet face each other, the connecting mechanism does not reduce the labor of the operator.

  An object of the present invention is to provide a vehicle seat device that reduces the labor of an operator when changing the arrangement of seats.

  A vehicle seat device that solves the above-described problems includes a plurality of seats that are slidably arranged along a vehicle front-rear direction, a locked state that is attached to each of the plurality of seats and restricts sliding of the seats, and A lock mechanism that switches between an unlocked state that allows a seat to slide, an electric actuator that is attached to each of the plurality of seats and that is connected to the lock mechanism and switches an operating state of the lock mechanism; An attitude detector that detects an attitude of at least one of the sheets, and the actuator attached to the predetermined sheet is configured so that the attitude detector of a sheet different from the predetermined sheet The lock mechanism of the predetermined seat is driven based on detecting the change in posture.

  According to the general procedure for changing the position (position and orientation) of a sheet, first the seat back of the sheet is tilted forward to change the position of the sheet, and in addition to other sheets Operate the actuator to change the arrangement of other sheets. Then, when the seat layout change is completed, the seat back is raised.

When this procedure is taken with reference to another sheet, it can be seen that the change of the arrangement of another sheet (predetermined sheet) is executed in response to a change in the posture of a sheet different from this other sheet.
Based on such facts, in the above configuration, the actuator attached to the predetermined sheet is based on the fact that the posture detection unit of a sheet different from the predetermined sheet detects the posture change of the other sheet. Drives the seat locking mechanism.

  According to such a configuration, even when it is necessary to move another sheet (predetermined sheet) in order to change the arrangement of a certain sheet, the other sheet (predetermined sheet) is changed by changing the posture of the sheet. Since the locked state of the sheet is changed, the operator's trouble when changing the arrangement of the sheet is reduced.

  In the vehicle seat device, the predetermined seat is one of two seats arranged adjacent to each other in the front-rear direction, and the other seat is the other of the two seats. is there.

  When the sheets are adjacent to each other in the front-rear direction, one sheet may hinder the change in the arrangement of the other sheet. For this reason, when the arrangement of the other sheet is changed, the frequency of changing the arrangement of the one sheet in conjunction with the change is high.

  Based on such facts, in the above configuration, the actuator attached to one sheet is based on the fact that the posture detection unit of the other sheet disposed adjacent to the other detects the posture change of the sheet. Drive the locking mechanism. For this reason, when the operator needs to change the arrangement of one sheet in conjunction with changing the arrangement of the other sheet, the operator needs to operate the lock mechanism attached to one sheet. There is no. For this reason, the trouble of the operator when changing the arrangement of the sheets is reduced.

  In the vehicle seat device, the predetermined seat indicates a front seat of two seats arranged so as to be adjacent to each other in the front-rear direction, and the another seat is a portion of the two seats. An actuator attached to the front seat drives the locking mechanism of the front seat based on the posture detection unit detecting a change in posture of the rear seat; It is preferable that the actuator attached to the rear seat drives the locking mechanism of the rear seat.

  In the vehicle seat device, at least each seat other than the front row includes a seat back detection unit that detects the posture of the seat back as the posture detection unit, and the seat back detection unit of the rear seat is the seat. The actuator attached to the front seat changes the lock mechanism of the front seat from the locked state to the unlocked state based on detecting the forward-turned state of the seat back. The actuator attached to the rear seat preferably changes the locking mechanism of the rear seat from the locked state to the unlocked state.

  According to the above configuration, the front seat and the rear seat can slide based on the fact that the seat back of the rear seat is brought forward. For this reason, the trouble of the operator when changing the arrangement of the sheets is reduced.

  In the vehicle seat device, the actuator attached to the front seat is based on the fact that the seat back detection unit of the rear seat detects the standing state of the seat back of the seat. The actuator for changing the locking mechanism of the seat from the unlocked state to the locked state, and being attached to the rear seat is configured so that the locking mechanism of the rear seat is changed from the unlocked state to the locked state. It is preferable to change to

  When the rear seat rearrangement is completed, it is preferable to lock both the front seat locking mechanism and the rear seat locking mechanism. According to the above configuration, the front seat locking mechanism and the rear seat locking mechanism are locked based on the fact that the rear seat is erected (that is, the position change is completed). For this reason, an operator's effort is reduced about the lock operation performed after the arrangement | positioning change of a sheet | seat.

  In the vehicle seat device, the rear seat can rotate with respect to the floor of the vehicle, and at least each seat other than the front row detects the posture of the seat back as the posture detection unit. A seat back detection unit; and a rotation detection unit that detects rotation of the seat, and the seat back detection unit of the rear seat detects a forward-turned state of the seat back of the seat, The actuator attached to the rear seat changes the locking mechanism of the rear seat from the locked state to the unlocked state, and the rotation detection unit of the rear seat detects the rearward rotation of the seat. The actuator attached to the front seat engages the locking mechanism of the front seat. It is preferable to change the serial locked state to the unlocked state.

  When the rear seat is turned rearward due to the rotation, the front seat may prevent the rear seat from rotating. Therefore, the rear seat placement is often changed along with the rear seat placement change. In the above configuration, based on such facts, the rear seat changes to the unlocked state based on the forward-turned state of the rear seat, and the front seat changes to the unlocked state based on the rotation of the rear seat. To do. For this reason, even when it is necessary to change the arrangement of the front seat when the rear seat is directed rearward, the operator does not need to operate the front seat locking mechanism. In this way, the operator's effort when turning the rear seat backward is reduced.

  In the vehicle seat device, the actuator attached to the front seat is based on the fact that the seat back detection unit of the rear seat detects the standing state of the seat back of the seat. The actuator for changing the locking mechanism of the seat from the unlocked state to the locked state, and being attached to the rear seat is configured so that the locking mechanism of the rear seat is changed from the unlocked state to the locked state. It is preferable to change to

  When the rear seat rearrangement is completed, it is preferable to lock both the front seat locking mechanism and the rear seat locking mechanism. According to the above configuration, the front seat locking mechanism and the rear seat locking mechanism are locked based on the fact that the rear seat is erected (that is, the position change is completed). For this reason, an operator's effort is reduced about the lock operation performed after the rear seat arrangement change.

  In the vehicle seat device, three or more of the seats are arranged in a line in the front-rear direction, and the predetermined seat is a seat disposed in front of a last row of the seats, The other sheet is the last row of the sheets, and each of the sheets other than at least the front row includes a seatback detection unit that detects the posture of the seatback as the posture detection unit, At least one of the actuators attached to each seat in front of the last row is based on the fact that the seat back detection unit detects the forward state of the seat back of the seat in the row. The actuator that changes the locking mechanism from the locked state to the unlocked state and is attached to the last row of seats is the last row. It is preferable to change the locking mechanism of the seat from the locked state to the unlocked state.

When a wide space is formed behind the passenger compartment by moving the last row of seats forward, the front seats may be moved forward together.
According to the above configuration, the lock mechanism attached to at least one front seat changes to the unlocked state based on the forward-turned state of the seat back of the last row of seats. Therefore, when the operator moves the last row of seats forward, even if it is necessary to move at least one front seat forward, the lock mechanism attached to the seat is brought into the unlocked state. There is no need to change. For this reason, the labor of the operator when moving the last row of sheets is reduced.

  In the vehicle seat device, the seat back detection unit of the last row of seats detects the standing state of the seat back of the seats, and is attached to each seat ahead of the last row. At least one of the actuators changes the locking mechanism of the seat from the unlocked state to the locked state, and the actuator attached to the last row of seats activates the locking mechanism of the last row of seats. It is preferable to change from the unlocked state to the locked state.

When the rearrangement of the last row of seats is completed, it is preferable to change at least one front seat maintained in the unlocked state to the locked state.
According to the above configuration, the lock mechanism attached to at least one front seat changes to the locked state based on the fact that the last row of seats has stood up (the arrangement change of the last row of seats has been completed). . For this reason, an operator's effort is reduced about the lock operation after the arrangement change of the sheet | seat of the last row is completed.

(First embodiment)
With reference to FIGS. 1-4, one Embodiment of the vehicle seat apparatus is described.
In the following description, “front” in the vehicle 60 (see FIG. 4) is defined as the side on which the steering 61 is attached, the front means the forward direction of the vehicle 60, and the rear means the opposite direction. means.

  As shown in FIG. 1, the vehicle seat apparatus 10 includes a lower rail 20A, 20B laid on a vehicle 60, three seats 30A to 30C slidably attached to the right lower rail 20A, and a left lower rail 20A. And three sheets 30D to 30F that are slidably attached to the body.

The right lower rail 20 </ b> A includes a pair of rails, and each rail is arranged in parallel to the vehicle width direction and extends in the front-rear direction of the vehicle 60 on the right side of the floor of the vehicle 60.
The left lower rail 20B includes a pair of rails, and each rail is arranged in parallel with the vehicle width direction and extends in the front-rear direction of the vehicle 60 on the left side of the floor of the vehicle 60.

  For the three seats 30A to 30C arranged on the right lower rail 20A, the first row of seats from the front is referred to as “the first right seat 30A”, and the second row of seats is “2”. The right sheet 30B in the row is referred to as “the right sheet 30C in the third row”. Regarding the three seats 30D to 30F arranged on the left lower rail 20B, the first row seat from the front is referred to as the “first left seat 30D”, and the second row seat is referred to as the “second row”. The left sheet 30E ”and the third row sheet are referred to as“ third row left sheet 30F ”.

  Further, when the sheets 30A to 30F are not distinguished, they are simply referred to as the sheet 30. Further, when the right lower rail 20A and the left lower rail 20B are not distinguished, they are simply referred to as the lower rail 20.

With reference to FIG. 2, the structure of the sheet | seat 30 is demonstrated.
The seat 30 includes a seat cushion 31, a seat back 32, and armrests 33 attached to the left and right side surfaces of the seat back 32. The armrest 33 is attached to the seat back 32 so that the angle can be changed.

  The seat 30 includes a lock mechanism 41, which will be described later, an actuator 42 that drives the lock mechanism 41, a seat back detection unit 43 (attitude detection unit), and a reclining device (not shown) for tilting and fixing the seat back 32. And a sheet rotating device (not shown) for rotating the sheet 30.

  Further, at the front portion of the seat cushion 31, there are provided a rotation lever 51 for allowing the rotation of the seat 30 and a front / rear movement lever 52 for fixing or sliding the seat 30 with respect to the lower rail 20. . Specifically, the forward / backward movement lever 52 switches an operation state of a lock mechanism 41 described later.

  A reclining lever 53 for changing the inclination of the seat back 32 is provided on a side portion of the seat cushion 31. The reclining device is operated by operating the reclining lever 53.

  A pedal 54 for allowing the seat 30 to slide relative to the lower rail 20 by moving the seat back 32 forward is provided at the rear portion of the seat cushion 31. By operating the pedal 54, the reclining device and the lock mechanism 41 are operated.

A pair of rails (hereinafter referred to as upper rails 34) disposed on the respective rails of the lower rail 20 are attached to the bottom of the seat 30.
Each rail of the lower rail 20 is provided with a plurality of locking holes at equal intervals along the extending direction. Also, each rail of the upper rail 34 is provided with a locking hole at the same interval as the locking hole provided in the lower rail 20. Each time the upper rail 34 slides by a predetermined distance with respect to the lower rail 20, the locking holes of the upper rail 34 and the locking holes of the lower rail 20 coincide with each other and communicate with each other (hereinafter referred to as ""Communicationholes"). The position of the upper rail 34 when the communication hole is formed in this way is referred to as a “lock position”.

The lock mechanism 41 fixes the seat 30 to the lower rail 20.
For example, the lock mechanism 41 includes a lock part (not shown), an elastic part that urges the lock part, and a limiter (not shown) that restricts movement of the lock part in the urging direction. The restricting unit restricts the movement of the lock component in the urging direction in a state where the lock component is moved in the direction opposite to the urging direction.

The lock mechanism 41 has a locked state and an unlocked state.
The lock state of the lock mechanism 41 indicates a state in which the lock component is allowed to move toward the lock hole of the upper rail 34. At this time, the movement of the lock part is not restricted by the restriction part.

  The unlocked state of the lock mechanism 41 indicates a state in which the lock parts are removed from the lock hole of the upper rail 34 and the lock hole of the lower rail 20. At this time, the movement of the lock part is restricted by the restriction part.

  When the upper rail 34 is in the locked position with respect to the lower rail 20, the locking hole of the upper rail 34 and the locking hole of the lower rail 20 overlap, and a communication hole is formed by both the locking holes. The lock mechanism 41 restrains the upper rail 34 with respect to the lower rail 20 by inserting a lock component into the communication hole.

  When the lock mechanism 41 is in a locked state (a state in which the urging movement of the lock component is not restricted) and the communication hole is formed, the lock component is inserted into the communication hole. On the other hand, the upper rail 34 is restrained. At this time, the seat 30 is fixed to the lower rail 20. Hereinafter, such a state of the seat 30 is referred to as a “slide restricted state”.

  When the lock mechanism 41 switches from the locked state to the unlocked state, the restraint on the upper rail 34 with respect to the lower rail 20 is released, and the seat 30 can slide. The state of the sheet 30 at this time is referred to as a “slidable state”.

The inclination angle of the seat back 32 with respect to the seat cushion 31 is changed by operating the reclining lever 53 of the seat 30.
Further, when the pedal 54 is operated, the seat 30 tilts the seat back 32 with respect to the seat cushion 31 and shifts from the slide restricted state to the slidable state.

The seat 30 shifts from the slide restricted state to the slidable state by operating the forward / backward movement lever 52.
Further, the seat 30 is in a state where the seat cushion 31 can be rotated by operating the rotation lever 51.

  The seat back detection unit 43 detects the posture of the seat back 32. For example, the seat back detection unit 43 includes a forward-turned state in which the seat back 32 is tilted forward by a predetermined angle or more (for example, a state in which the seat back 32 is tilted to the extent that the seat back 32 contacts the seat cushion 31) It is detected which one of the upright standing states. Then, the seat back detection unit 43 outputs a predetermined posture detection signal corresponding to each of the forward-turned state and the standing-up state. Further, the seat back detection unit 43 outputs a posture detection signal to the actuator 42 and the actuator 42 attached to the front seat 30 via a signal line for transmitting and receiving an electrical signal. This signal line is disposed in the rail internal space of the lower rail 20 extending in the front-rear direction.

  The actuator 42 drives an arm unit by an electric drive source such as a motor based on a signal output from the seat back detection unit 43, and drives a lock mechanism 41 linked to the arm unit. That is, the state of the lock mechanism 41 is switched by the operation of the actuator 42 based on the signal output from the seat back detection unit 43.

  The actuator 42 is used for locking the locking hole of the upper rail 34 and the locking of the lower rail 20 based on the attitude detection signal indicating the forward-turned state output from the seatback detection unit 43 (the following (signal A1) or (signal A2)). Pull out the lock part that is inserted into the hole communicating with the hole. Thereby, the lock mechanism 41 is switched from the locked state to the unlocked state.

(Signal A1) An attitude detection signal indicating a forward-turned state output from the seat back detection unit 43 of the seat 30 to which the actuator 42 is attached.
(Signal A2) A posture detection signal indicating a forward-turned state output from the seat back detection unit 43 provided on the seat 30 behind the seat 30 to which the actuator 42 is attached.

  On the other hand, when neither the (signal A1) nor the (signal A2) is received, the actuator 42 performs an operation of pulling out the lock component inserted into the communication hole between the lock hole of the upper rail 34 and the lock hole of the lower rail 20. Do not execute.

  The actuator 42 is based on the attitude detection signal indicating the standing state output from the seat back detection unit 43 (the following (Signal B1) or (Signal B2)), and the locking hole of the upper rail 34 and the locking hole of the lower rail 20 Insert the lock part into the communication hole. As a result, the lock mechanism 41 is switched from the unlocked state to the locked state.

(Signal B1) An attitude detection signal indicating the standing state, which is output from the seat back detection unit 43 of the seat 30 to which the actuator 42 is attached.
(Signal B2) A posture detection signal indicating a standing state, which is output from the seat back detection unit 43 provided in the seat 30 behind the seat 30 to which the actuator 42 is attached.

Next, the operation of the vehicle seat device 10 will be described.
Referring to FIGS. 3 and 4, an operation for changing the arrangement (position and orientation) of sheet 30 when the operator uses left sheet 30F in the third row, and the sheet set at that time The state 30 will be described.

FIG. 3 shows an operation procedure when the left sheet 30F in the third row is used.
In addition, as shown in FIG. 4A, the state before changing the arrangement of the seats 30 is arranged such that the seat backs 32 stand up, face forward, and are spaced apart in the front-rear direction. In the following description, it is assumed that the slide restriction state is set (hereinafter referred to as “reference sheet arrangement”).

  FIG. 4 shows the arrangement of the seat 30 of the vehicle seat device 10. FIG. 4A shows the sheet arrangement before the arrangement of the sheet 30 is changed. FIG. 4B shows a seat arrangement in a state where the seat back 32 of the left seat 30E in the second row is tilted forward (a forward-turned state). FIG. 4C shows the sheet arrangement in a state where the left sheet 30E in the second row is moved forward. FIG. 4D shows a sheet arrangement in a state where the left sheet 30E in the second row and the left sheet 30D in the first row are moved forward. FIG. 4E shows the seat arrangement in a state where the seat back 32 of the left seat 30E in the second row is raised.

  The operator tilts the seat back 32 of the left sheet 30E in the second row with respect to the sheet 30 set as the reference sheet arrangement in step S11, thereby arranging the sheet arrangement of the sheets 30 in FIG. Set to the sheet layout shown in.

  When this sheet arrangement is set, the seat back detection unit 43 of the left sheet 30E in the second row detects the tilting (forward movement state) of the seat back 32. The seat back detection unit 43 outputs a posture detection signal to the actuator 42 of the left seat 30E in the second row and outputs a posture detection signal to the actuator 42 of the left seat 30D in the first row. The actuator 42 attached to the left seat 30E in the second row and the left seat 30D in the first row switches the lock mechanism 41 to the unlocked state based on this posture detection signal. For this reason, the left sheet 30E in the second row and the left sheet 30D in the first row are set in a slidable state.

  Next, in step S12, the operator slides the left sheet 30E in the second row, which is set in a slidable state, forward to a position in contact with the left sheet 30D in the first row. Further, the operator continues to push the left sheet 30E in the second row by pressing the left sheet 30E in the second row after the left sheet 30E in the second row comes into contact with the rear portion of the left sheet 30D in the first row. The left sheet 30E in the row and the left sheet 30D in the first row are simultaneously slid forward. Then, the both sheets 30D and 30E are slid until the left sheet 30D in the first row reaches the foremost position within the slidable range.

  By such an operation, the operator can arrange the sheets 30 in a state where the space between the left sheet 30E in the second row and the left sheet 30F in the third row is expanded (hereinafter referred to as “walk-in state”). (Refer to FIG. 4D).

  In this walk-in state, the operator uses the space between the left seat 30E in the second row and the left seat 30F in the third row, that is, the space extending in front of the left seat 30F in the third row. Therefore, it is possible to smoothly get on and off from the side door of the vehicle 60 (step S13).

  After the passenger (or the operator) has boarded the left seat 30F in the third row, the operator returns the seat arrangement set to the walk-in state to the original in step S14. Specifically, the seat back 32 of the left seat 30E in the second row is raised. In this way, the operator sets the vehicle seat device 10 to the seat arrangement shown in FIG.

  At this time, the seat back detection unit 43 of the left seat 30E in the second row detects the standing of the seat back 32, and the actuator 42 attached to the left seat 30E in the second row and the left seat in the first row. An attitude detection signal indicating that the actuator 42 attached to the seat 30D is in a standing state is output. The actuator 42 attached to the left seat 30E in the second row and the left seat 30D in the first row switches the lock mechanism 41 to the locked state based on this attitude detection signal. For this reason, in the left seat 30E in the second row and the left seat 30D in the first row, the lock mechanism 41 is switched from the unlocked state to the locked state. When the seats 30D and 30E are in the locked position, they are fixed to the lower rail 20. When the seats 30D and 30E are shifted from the locked position, the seats 30D and 30E are fixed to the lower rail 20 by moving the seats 30D and 30E to the locked position.

  Next, in step S15, the operator operates the back-and-forth movement lever 52 to slide the left seat 30E in the second row and the left seat 30D in the first row backward, thereby arranging the seat arrangement of the seat 30. Is set to the reference sheet arrangement shown in FIG.

  In the operation procedure of the sheet 30, when the sheet 30 set in the walk-in state is returned to the original arrangement, after the second row of sheets 30 is raised, the first row and the second row of sheets 30D, Although 30E is moved to the original position (step S14, step S15), this order may be changed. That is, the first row and second row sheets 30 may be moved to their original positions before the second row sheets 30 are erected.

According to this embodiment, the following effects can be obtained.
(1) The actuator 42 of the predetermined sheet 30 operates based on the posture detection unit (for example, the seat back detection unit 43) of another sheet 30 detecting the posture change of the other sheet 30. The lock mechanism 41 of the seat 30 is driven. For this reason, even when it is necessary to move another sheet 30 (predetermined sheet 30) in order to change the arrangement (position or orientation) of the sheet 30, there is another change as the posture of the sheet 30 is changed. Since the lock state of the seat 30 (predetermined seat 30) is changed, the labor of the operator when changing the arrangement of the seat 30 is reduced.

  In addition, the present technology has the effect regardless of the arrangement mode regardless of the sheet arrangement related to the setting. That is, according to the present technology, any seat such as a walk-in state seat arrangement, a facing seat arrangement (see the second and third embodiments), and a seat arrangement that widens the cargo compartment (see the fourth embodiment) can be used. Even in the case of setting the arrangement, the other sheets 30 (predetermined sheets 30) are automatically unlocked based on the posture change of a certain sheet 30. As described above, the present technology is applicable regardless of the sheet arrangement mode.

  (2) Since one of the sheets 30 arranged in the front-and-rear direction may interfere with a change in the arrangement of the other sheet 30, one of the sheets 30 arranged in the front-and-rear direction is It is preferable to drive the lock mechanism 41 of one of the sheets 30 based on the posture change of the sheet 30.

  (3) In particular, when changing the arrangement of the rear seats 30 among the front and rear seats 30 arranged, the rear seat 30 is often prevented from being changed by the front seats 30. For this reason, it is preferable that the actuator 42 of the front seat 30 drives the lock mechanism 41 of the front seat 30 based on the posture detection unit of the rear seat 30 detecting the posture change of the seat 30.

  (4) In the present embodiment, the actuator 42 attached to the front seat 30 detects the forward position of the seat back 32 output by the seat back detector 43 attached to the rear seat 30. Based on the signal, the lock mechanism 41 is changed from the locked state to the unlocked state. For this reason, even if the operator needs to move the front seat 30 when the seat back 32 of the rear seat 30 is moved forward and moved forward, the lock mechanism attached to the front seat 30 is required. Since 41 is in the unlocked state, the operator does not need to operate the lock mechanism 41 of the front seat 30. For this reason, an operator's effort when changing arrangement | positioning of the sheet | seat 30 is reduced.

  (5) The actuator 42 attached to the front seat 30 is based on a posture detection signal indicating the standing state of the seat back 32 of the rear seat 30 output from the seat back detection unit 43 of the rear seat 30.

  Next, in step S <b> 23, the operator slides the second row of left seats 30 </ b> E set in a slidable state forward and slides the first row of left seats 30 </ b> D forward. Then, the both sheets 30D and 30E are slid until the left sheet 30D in the first row reaches the foremost position within the slidable range. By this operation, the operator sets the sheet arrangement of the sheets 30 in a state where the space between the left sheet 30E in the second row and the left sheet 30F in the third row is widened (FIG. 6B). reference).

  Thereafter, in step S24, the operator raises the seat back 32 of the left seat 30E in the second row. In this way, the operator sets the sheet arrangement of the sheet 30 to the sheet arrangement shown in FIG. Further, by this operation (operation in step S24), the seat back detection unit 43 of the left seat 30E in the second row detects the standing of the seat back 32, and the actuator attached to the left seat 30E in the second row. 42 and an attitude detection signal indicating that the actuator 42 attached to the left seat 30D in the first row is in an upright state. The actuator 42 attached to the second sheet 30E in the second row and the left sheet 30D in the first column switches the lock mechanism 41 to the locked state based on receiving this posture detection signal. At this time, the lock component moves toward the lock hole of the upper rail 34. When the communication hole between the lock hole of the upper rail 34 and the lock hole of the lower rail 20 is formed, the seat 30 is fixed to the lower rail 20 because the lock member is inserted into the communication hole.

  When the communication hole between the locking hole of the upper rail 34 and the locking hole of the lower rail 20 is not formed, the operator removes the left seat 30E in the second row and the left seat 30D in the first row in step S25. The seats 30D and 30E are fixed to the lower rail 20 by sliding to the lock position.

By such an operation, the left seat 30E in the second row and the left seat 30F in the third row are set in the facing seat arrangement.
The operator can set the right seat 30B in the second row and the right seat 30C in the third row in the facing seat arrangement by the same operation procedure as that shown in FIG.

  Referring to FIG. 7, an operation procedure for returning the second sheet left seat 30 </ b> E set to the facing seat arrangement and the first sheet left sheet 30 </ b> D moving forward to the reference sheet arrangement ( The operation procedure when returning) will be described. This operation is performed on the assumption that the arrangement of the seats 30 is the facing seat arrangement.

  In step S31, the operator tilts the seat back 32 of the left seat 30E in the second row facing backward, thereby setting each seat 30 to the seat arrangement shown in FIG. 6B. At this time, the seat back detection unit 43 of the left seat 30E in the second row detects the tilting (forward movement state) of the seat back 32. The seat back detection unit 43 outputs a posture detection signal indicating a forward-turned state to the actuator 42 of the left seat 30E in the second row and forward-turns to the actuator 42 of the left seat 30D in the first row. A posture detection signal indicating is output. The actuator 42 attached to the left seat 30E in the second row and the left seat 30D in the first row switches the lock mechanism 41 to the unlocked state based on this posture detection signal. For this reason, the left sheet 30E in the second row and the left sheet 30D in the first row are set in a slidable state.

  Next, in step S32, the operator sets the sheet arrangement shown in FIG. 6A by sliding the left sheet 30E in the second row backward. In step S33, the operator rotates the left seat 30E in the second row so as to face forward.

  Thereafter, in step S34, the operator raises the seat back 32 of the left seat 30E in the second row. At this time, the seat back detection unit 43 of the left seat 30E in the second row detects the standing of the seat back 32, and the actuator 42 attached to the left seat 30E in the second row and the left in the first row An attitude detection signal indicating that the actuator 42 attached to the seat 30D is in a standing state is output. The actuator 42 attached to the second sheet 30E in the second row and the left sheet 30D in the first column switches the lock mechanism 41 to the locked state based on receiving this posture detection signal. For this reason, the left seat 30 </ b> E in the second row and the left seat 30 </ b> D in the first row are fixed or fixable to the lower rail 20.

  Next, in step S35, the operator operates the back-and-forth movement lever 52 so that the left sheet 30E in the second row and the left sheet 30D in the first row are positioned at the reference sheet arrangement shown in FIG. Slide to. Accordingly, the left sheet 30E in the second row and the left sheet 30D in the first row are fixed in the arrangement of the reference sheet arrangement.

According to the present embodiment, the same effects as in the first embodiment, that is, the effects (1) to (5) can be obtained.
For example, in the present embodiment, the actuator 42 attached to the front seat 30 is a posture detection signal indicating the forward-turned state of the seat back 32 output by the seat back detection unit 43 attached to the rear seat 30. Based on the above, the lock mechanism 41 is changed from the locked state to the unlocked state. Therefore, when the operator needs to move the front seat 30 when the seat back 32 of the rear seat 30 is moved forward and moved forward, the lock attached to the front seat 30 is required. Since the mechanism 41 is in the unlocked state, the operator does not need to operate the lock mechanism 41 of the front seat 30. For this reason, an operator's effort when changing arrangement | positioning of the sheet | seat 30 is reduced.

(Third embodiment)
Next, the vehicle seat device 10 according to the third embodiment will be described with reference to FIGS. 4, 5, and 6. The main difference between the present embodiment and the first embodiment is that the second row of sheets 30 includes a rotation detection unit (attitude detection unit). For convenience of explanation, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The right seat 30B in the second row and the left seat 30E in the second row of the third embodiment have a rotation detector (not shown) that detects the rotation angle of the seat cushion 31 inside the seat cushion 31. Yes.

The rotation detection unit detects an initial movement when the seat 30 rotates rearward from the forward state and an initial movement when the seat 30 rotates forward from the rearward state.
For example, the rotation detection unit is configured to detect the rotation angle of the seat cushion 31. The rotation detection unit outputs a rotation detection signal indicating the initial rotation when detecting that the seat cushion 31 has rotated at a predetermined angle. Specifically, when the rotation detection unit starts to rotate so that the front-facing seat 30 faces rearward (hereinafter referred to as “start of rearward rotation”), a rotation detection signal indicating the start of rearward rotation. Is output to the actuator 42 of the front seat 30. In addition, when the rotation detection unit starts to rotate so that the seat 30 facing backward is directed forward (hereinafter referred to as “start of forward rotation”), a rotation detection signal indicating the start of forward rotation is transmitted to the front. This is output to the actuator 42 of the sheet 30.

  The actuator 42 receives the following signal 1 or receives the signal 2, and thereby pulls out the locking component inserted into the communication hole between the locking hole of the upper rail 34 and the locking hole of the lower rail 20. Thereby, the lock mechanism 41 is switched from the locked state to the unlocked state.

Signal 1: A posture detection signal indicating a forward-turned state output from the seat back detection unit 43 of the seat 30 to which the actuator 42 is attached.
Signal 2: A rotation detection signal indicating the start of rearward rotation, which is output from a rotation detector provided on the rear seat 30 of the seat 30 to which the actuator 42 is attached.

  For example, the actuator 42 of the left seat 30D in the first row is in the second row even when the seat back detection unit 43 of the left seat 30E in the second row outputs a posture detection signal indicating a forward-turned state. When the rotation detection unit of the left seat 30E of the left does not output a rotation detection signal indicating the start of backward rotation, the lock mechanism 41 is held in the locked state.

  The actuator 42 of the left sheet 30D in the first row receives this signal when the rotation detection unit of the left sheet 30E in the second row outputs a rotation detection signal indicating backward rotation, and receives the lock mechanism 41. Switch the locked state to unlocked state.

  Referring to FIG. 5, an operation for setting the left seat 30 </ b> E in the second row and the left seat 30 </ b> F in the third row to the facing seat arrangement using the vehicle seat device 10 configured as described above. The operation procedure will be described.

  As shown in FIG. 5, in step S21, the operator tilts the seat back 32 of the left seat 30E in the second row forward. As a result, the operator changes the reference sheet arrangement shown in FIG. 4A to the sheet arrangement shown in FIG. In this state, as described above, the left sheet 30E in the second row is set in a slidable state. At this time, the left seat 30 </ b> D in the first row is fixed to the lower rail 20.

  In step S22, the operator sets the sheet arrangement shown in FIG. 6A by rotating the left sheet 30E in the second row so as to face backward. At this time, the rotation detection unit of the left seat 30E in the second row detects that the seat cushion 31 has rotated at a predetermined angle. Then, the rotation detection unit outputs a rotation detection signal indicating the start of backward rotation. At this time, the actuator 42 of the left seat 30D in the first row receives the rotation detection signal indicating the start of the backward rotation of the left seat 30E in the second row, so that the lock mechanism 41 is switched to the unlocked state.

  Thereafter, the operator sequentially performs the same steps S23 to S25 as described in FIG. 5, thereby setting the left sheet 30E in the second row and the left sheet 30F in the third row to the facing seat arrangement.

  Next, an operation procedure for returning the left seat 30E in the second row set to the facing seat arrangement and the left seat 30D in the first row moving forward to the reference sheet arrangement (operation at the time of return) Procedure) is explained. This operation is performed on the assumption that the arrangement of the seats 30 is the facing seat arrangement.

  When changing the facing seat layout to the reference seat layout, first, the same operations as those shown in steps S31 and S32 are performed. That is, by tilting the seat back 32 of the left seat 30E in the second row facing rearward, the left seat 30E in the second row and the left seat 30D in the first row are set in a slidable state ( (See FIG. 6 (a)).

  Next, the operator rotates the left sheet 30E in the second row so as to face forward. At this time, the rotation detection unit of the left seat 30E in the second row detects the forward rotation of the seat 30E, and the rotation detection signal indicating the start of forward rotation to the actuator 42 attached to the left seat 30D in the first row. Is output. The actuator 42 attached to the left seat 30D in the first row switches the lock mechanism 41 to the locked state based on receiving this rotation detection signal.

  Next, the operator erects the seat back 32 of the left seat 30E in the second row. At this time, the seat back detection unit 43 of the left seat 30E in the second row detects that the seat back 32 has stood up, and the actuator 42 attached to the left seat 30E in the second row has stood up. The attitude detection signal shown is output. The actuator 42 attached to the left seat 30E in the second row switches the lock mechanism 41 to the locked state based on receiving this posture detection signal. For this reason, the left seat 30 </ b> E in the second row is fixed or fixable to the lower rail 20.

  Next, the operator operates the forward / backward movement lever 52 to slide the left sheet 30E in the second row and the left sheet 30D in the first row to the position of the reference sheet arrangement shown in FIG. Accordingly, the left sheet 30E in the second row and the left sheet 30D in the first row are fixed in the arrangement of the reference sheet arrangement.

According to this embodiment, in addition to the effects (1) to (3) of the first embodiment, the following effects can be obtained.
(4) The second row of sheets 30 further includes a rotation detection unit that detects the rotation of the seat back 32. The actuator 42 of the front seat 30 changes the lock mechanism 41 of the seat 30 from the locked state to the unlocked state based on the rotation detection signal of the rotation detection unit (posture detection unit) of the rear seat 30. That is, based on the rotation detection signal of the rotation detection unit of the rear seat 30, the front lock mechanism 41 changes from the locked state to the unlocked state.

  For this reason, even when the operator needs to change the arrangement of the front seat 30 in order to turn the rear seat 30 backward, the operator uses the lock mechanism 41 attached to the front seat 30. There is no need to operate. For this reason, an operator's effort when turning the back seat | sheet 30 back is reduced.

  (5) When the locking mechanism 41 of the first row of seats 30 and the locking mechanism 41 of the second row of seats 30 are both unlocked, and the second row of seats 30 are disposed rearward (ie, facing each other) In the state immediately before reaching the sheet arrangement), each actuator 42 operates as follows (see FIG. 5, steps S24 and S25).

  That is, when the seat back detection unit 43 of the seat 30 in the second row outputs an attitude detection signal indicating the standing state of the seat back 32 of the seat 30 (that is, when the arrangement change is completed), each actuator 42 To work. The actuator 42 in the first row changes the locking mechanism 41 of the seat 30 from the unlocked state to the locked state, and the actuator 42 in the second row seat 30 moves the locking mechanism 41 of the seat 30 from the unlocked state to the locked state. To change. For this reason, an operator's effort is reduced about the lock operation performed after the arrangement | positioning change of the sheet | seat 30 of the 2nd row.

(Fourth embodiment)
Next, with reference to FIG.4, FIG8 and FIG.9, the vehicle seat apparatus 10 which concerns on 4th Embodiment is demonstrated. The main difference between this embodiment and the first embodiment is the arrangement of the sheets 30. For this reason, for convenience of explanation, the same components are denoted by the same reference numerals as those in the first embodiment, and description thereof is omitted.

  FIG. 8 shows an operation procedure for expanding the space in the luggage compartment behind the third row of seats 30 in the vehicle by moving all the seats 30 forward. FIG. 9 shows the sheet arrangement set at that time.

  As shown in FIG. 8, in step S41, the operator moves the seat back 32 of the third row of seats 30C, 30F of the vehicle seat device 10 set to the reference seat arrangement shown in FIG. Is set to the sheet arrangement shown in FIG. By this operation, the seat back detection unit 43 of the third row of seats 30C and 30F detects the forward-turned state of the seat back 32, and the third row of sheets 30C and 30F, the second row of sheets 30B and 30E, and Posture detection signals indicating the forward-turned state are output to the actuators 42 included in the first row of sheets 30A and 30D. For this reason, all the sheets 30 are set in a slidable state.

  Next, in step S42, the operator places the third row of seats 30C and 30F, the second row of seats 30B and 30E, and the first row of seats 30A and 30D that are set in a slidable state forward. By sliding, the sheet arrangement shown in FIG. 9B is set. For this reason, the space of the luggage compartment behind the 3rd row | line seats 30C and 30F is expanded.

  In step S43, the operator raises the seat back 32 of the seats 30C and 30F in the third row to set the sheet arrangement shown in FIG. By this operation, the seat back detection unit 43 of the third row of sheets 30C and 30F detects the standing of the seat back 32, and the third row of sheets 30C and 30F, the second row of sheets 30B and 30E, and 1 Posture detection signals indicating the standing state are output to the actuators 42 included in the sheets 30A and 30D in the row. For this reason, the lock mechanisms 41 of all the sheets 30 are switched from the unlocked state to the locked state. Thereafter, in step S44, the operator moves the seat 30 to the lock position to place the seat 30 in a slide restricted state (a state in which the lock member is inserted into the communication hole).

According to the present embodiment, in addition to the effect (1) of the first embodiment, the following effects can be obtained.
(6) The actuators 42 of the first row seats 30A and 30D and the second row seats 30B and 30E are moved forward by the seat back 32 output from the seat back detection unit 43 of the third row seats 30C and 30F. Based on the posture detection signal indicating the state, the lock mechanism 41 is changed from the locked state to the unlocked state.

  Therefore, even if the operator needs to move the first row of sheets 30 and the second row of sheets 30 forward in order to move the third row of seats 30 forward, these sheets 30 Therefore, the operator does not need to change the lock mechanism 41 of these seats 30 to the unlocked state. For this reason, an operator's effort at the time of moving the sheet | seat 30 of the 3rd row is reduced.

  (7) The actuators 42 of the first row of seats 30 and the second row of seats 30 output posture detection signals indicating the standing state of the seat back 32 output from the seat back detection unit 43 of the third row of seats 30. Based on this, the lock mechanism 41 is changed from the locked state to the unlocked state. For this reason, an operator's effort is reduced about the lock operation after the arrangement | positioning change of the sheet | seat 30 of the 3rd row is completed.

The vehicle seat device 10 according to the above embodiment can be modified as follows.
In the second and third embodiments, the seat back 32 of the first row of seats 32 may be automatically raised in the process of changing the seat 30 from the reference seat placement to the facing seat placement. For example, when the locking mechanism 41 of the first row of seats 30 is changed to the unlocked state in the process of changing the seat 30 from the reference seat arrangement to the facing seat arrangement, or when the first row of seats 30 slides When the position is reached, the seat back 32 of the seat 30 in the first row is set to the upright state based on any of these events. According to this configuration, the second row of seats 30 can be disposed further forward, and the space between the second row of seats 30 and the third row of seats 30 can be expanded.

  In the third embodiment, the rotation detection unit may include a switch that switches a state when the seat cushion 31 is rotated beyond a predetermined rotation angle in the vehicle width direction. And a rotation detection part may detect that the sheet | seat 30 rotated by the state of a switch switching.

  In the first to fourth embodiments, the seat back detection unit 43 may have a switch that switches a state when the seat back 32 tilts beyond a predetermined angle. And the seat back detection part 43 may detect that the seat back 32 tilted by the state of a switch switching.

  In the first to fourth embodiments, when the seat back detection unit 43 of the second row or third row of seats 30 detects the tilting (forward-falling state) of the seat back 32, or the second row of seats 30. When the rotation detection unit detects the start of rearward rotation, the lock mechanism 41 of the front seat 30 is unlocked. However, if the lock mechanism 41 is driven while the occupant is seated on the front seat 30, the occupant may feel uncomfortable. Therefore, when a passenger is seated on the front seat 30, it is preferable that the lock mechanism 41 is not driven regardless of the posture change of the rear seat 30.

  In the first to fourth embodiments, when the seat back detection unit 43 of the second row or third row of seats 30 detects the tilting (forward movement state) of the seat back 32, the seat back detection unit 43 An attitude detection signal is output to the actuator 42 of the seat 30 to drive its own lock mechanism 41.

  By the way, in the vehicle seat device 10, the lock mechanism 41 is mechanically unlocked in conjunction with the tilting (forward tilted state) of the seat back 32, and mechanically locked in conjunction with the standing state of the seat back 32. There is a case in which the mechanism 41 is configured to be in a locked state. In this case, since it is not necessary to drive the locking mechanism 41 of the seat 30 to be rearranged by the actuator 42, the actuator 42 of the seat 30 to be rearranged is configured not to drive the locking mechanism 41 of the seat 30. It is preferable.

  Even in such a configuration, when the operator tilts the seat back 32 of the seat 30 forward in order to change the position (or orientation) of an arbitrary seat 30, the actuator 42 attached to another seat 30 is used. The lock mechanism 41 of the other seat 30 changes from the locked state to the unlocked state. For this reason, even when it is necessary to move another sheet 30 in order to change the position (or orientation) of an arbitrary sheet 30, the operator can change the operation state of the lock mechanism 41 of the other sheet 30. There is no need to switch to the unlocked state. For this reason, an operator's effort at the time of changing the position (or direction) of the sheet | seat 30 is reduced.

  -The technology shown in the first to fourth embodiments is the vehicle seat device 10 in which two seats 30 are arranged on each lower rail 20 or the vehicle in which four or more seats 30 are arranged on each lower rail 20. The present invention can also be applied to the sheet apparatus 10 for use.
