  It is desired to develop a vehicle seat structure that can easily access a child seat fixed to a rear seat on the passenger side from the driver's seat.

  When the child seat is fixed to the passenger seat as described above, the driver can easily put the child on the child seat on the driver seat or take it down from the child seat. Therefore, the driver can get on and off the driver's seat door with the child. In addition, the driver can easily check the state of the child on the child seat while driving.

  However, while the child seat is desired to remain fixed to the vehicle-mounted seat, the passenger seat is desired to remain available without fixing the child seat. This is because the child seat is likely to be troublesome to attach and detach, and the passenger seat is generally used frequently.

  Therefore, it is possible to fix the child seat to the rear seat on the passenger seat side. Then, the passenger seat can be left in a usable state while the child seat is fixed to the in-vehicle seat. In addition, the driver can easily check the state of the child riding on the child seat while driving by using an inner mirror (rear view mirror) on the driver's seat.

  However, when the child seat is fixed to the rear seat on the passenger seat side, it is very difficult for the driver to put the child on the child seat on the driver's seat or to remove the child seat from the child seat. This is because the distance between the driver's seat and the rear seat on the passenger side is generally far, and it is difficult for the driver to access the rear seat on the passenger's seat on the driver's seat. Therefore, it is difficult for the driver to get on and off the driver's seat door together with the child. When the child seat is fixed to the rear seat on the passenger side, the driver and the child must get on the vehicle from the rear seat door on the passenger side to the child seat, after the driver has placed the child on the child seat. Will go around. On the other hand, when the driver and the child get off, the driver gets out of the driver's seat door and goes around the vehicle to the rear seat door on the passenger seat side. Accordingly, it is very complicated for the driver and the child to get on and off.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle seat structure in which a child seat fixed to a passenger seat rear seat can be easily accessed from a driver seat.

  A vehicle seat structure according to an aspect of the present invention includes a driver's seat, a rear seat on the passenger seat side, a mounting detector, a position detector, and a moving mechanism. The driver's seat can slide forward and backward of the vehicle. The child seat is detachable from the rear seat on the passenger side. The mounting detection unit detects that the child seat is mounted on the rear seat on the passenger seat side. The position detection unit detects that the driver's seat has moved to a predetermined rear position. The moving mechanism moves the child seat forward based on the detection results of the mounting detector and the position detector.

  According to the vehicle seat structure described above, the distance between the driver's seat and the child seat can be reduced, so that the child seat can be easily accessed from the driver's seat. Therefore, the driver can easily put the child on the child seat mounted on the rear seat of the passenger seat on the driver's seat or take it off from the child seat. Therefore, the driver can get on and off the car from the driver's seat door together with the child. That is, when the driver and the child get on, the driver does not need to go around the vehicle to the driver seat door after the driver puts the child on the child seat from the rear seat door on the passenger side outside the vehicle. When the child gets off, there is no need for the driver to get off the driver's seat door and go around the vehicle to the rear seat door on the passenger side.

Embodiment 1
[Vehicle seat structure]
A vehicle seat structure 1A according to Embodiment 1 includes a driver's seat 2 that is slidable in the front-rear direction and a rear seat 3 on the passenger seat side that is detachable from the child seat 4. The main feature of the vehicle seat structure 1A is that a mounting detection unit 5 that detects that the child seat 4 is mounted on the rear seat 3 on the passenger seat side, and the driver's seat 2 slides to a predetermined rear position. The position detection unit 6 detects this, and a moving mechanism 7 that moves the child seat 4 forward based on the detection results of the detection units 5 and 6. Details will be described below.

[driving seat]
The driver's seat 2 is provided so as to be slidable in the longitudinal direction of the vehicle along rails (not shown) on the floor panel. The driver's seat 2 may use a manual seat (manual seat) in which the slide movement before and after is manually released by locking the slide, or a power seat (operated by operating a motor with a switch) An electric seat) may be used.

[Rear seat on the passenger side]
A child seat 4 is detachably attached to the rear seat 3 on the passenger seat side. A power seat can be used as the rear seat 3 on the passenger seat side. As for the type of the rear seat, the left and right seats may be individual separate seats, or the left and right seats may be an integral bench seat. For example, when the moving mechanism 7 described later advances the rear seat 3 itself on the passenger seat side, the rear seat may be a separate seat.

  When the child seat 4 is of the ISOFIX type, the rear seat 3 on the passenger seat side is inserted into the connector 41 (FIGS. 1 and 2) of the child seat 4 and engaged with the connector 41, so that the child seat 4 is An anchor 31 (FIG. 2) to be fixed to the seat 3 is provided. The anchor 31 is provided integrally with the rear seat 3 via an ISOFIX bar (not shown).

[Installation detection unit]
The mounting detector 5 detects that the child seat 4 is mounted on the rear seat 3 on the passenger seat side (FIG. 2). The arrangement location and type of the mounting detection unit 5 are not particularly limited, and can be appropriately selected according to the type (fixing method) of the child seat 4.

  When the child seat 4 is an ISOFIX type, the mounting detection unit 5 may be configured by an engagement sensor that detects that the anchor 31 and the connector 41 of the child seat 4 are engaged. For example, the engagement sensor is provided on the anchor 31 and includes a switch that is turned on by the connector 41 when the connector 41 is engaged with the anchor 31 and is turned off when the engagement is released. Is mentioned. In the case where the child seat 4 is a seat belt fixed type, the mounting detection unit 5 may be configured by a pressure sensor or the like that detects the load of the child seat 4. For example, the pressure sensor may be incorporated in the seat cushion of the rear seat 3. A known configuration can be used for the mounting detector 5.

[Position detector]
The position detector 6 detects that the driver's seat 2 has moved to a predetermined rear position (FIG. 2). The predetermined rear position refers to the rear of the rear end of the normal sliding amount of the driver's seat 2. Examples of the normal slide amount include a slide amount necessary for the driver to take a driving posture corresponding to the physique at the driver's seat 2. Examples of the predetermined rear position include a position where the child seat 4 can be easily accessed from the driver's seat 2 when the moving mechanism 7 described later moves the child seat 4 forward. That is, even if the driver's seat 2 does not move to the rear end of the slidable range, the driver's seat 2 may be closer to the rear end as long as it is accessible. Of course, the predetermined rear position may be the rear end of the slidable range of the driver's seat 2. It is preferable that the position detection unit 6 also detects that the driver's seat 2 has moved forward from a predetermined rear position.

  The arrangement location and type of the position detection unit 6 are not particularly limited, and can be appropriately selected according to the predetermined rear position. The position detection unit 6 includes, for example, a sensor including a switch that is turned on by the driver's seat 2 when the driver's seat 2 moves backward to a predetermined rear position and is turned off when the driver's seat 2 moves forward from the predetermined rear position. Can be mentioned. More specifically, a contact sensor such as a micro switch, a non-contact sensor such as a photoelectric sensor, and the like can be given.

[Movement mechanism]
The moving mechanism 7 moves the child seat 4 back and forth. The front and rear movement of the child seat 4 may be performed by moving the rear seat 3 on the passenger seat side to which the child seat 4 is fixed back and forth, or only the child seat 4 on the rear seat 3 and the rear seat 3 on the passenger seat side. May be performed independently. In order to move the rear seat 3 on the passenger seat side back and forth, the power seat motor is operated. In order to move only the child seat 4 back and forth on the rear seat 3, it is possible to use a link mechanism or a slide mechanism that can move the child seat 4 back and forth. These link mechanisms and slide mechanisms are electrically operated so that they can be operated by a movement control unit 8 described later. By moving the child seat 4 forward, the distance between the child seat 4 and the driver's seat 2 can be reduced. Therefore, it is easy to access the child seat 4 from the driver seat 2. If the child seat 4 is moved backward after the child seat 4 has moved forward, the child seat 4 can be returned to the initial position. The movement control unit 8 can control the forward and backward movement of the child seat 4 by the moving mechanism 7.

[Movement control unit]
The movement control unit 8 instructs the movement mechanism 7 to advance and reverse the child seat 4 based on the detection results of the mounting detection unit 5 and the position detection unit 6. Specifically, a computer such as an ECU (Electronic Control Unit) can be used. The forward control command to the moving mechanism 7 by the movement control unit 8 is that the detection result that the child seat 4 is mounted on the rear seat 3 on the passenger seat side by the mounting detection unit 5 and the driver seat 2 by the position detection unit 6 is predetermined. It is performed in response to both the detection result and the detection result that it has moved to the rear position. The backward movement command to the movement mechanism 7 by the movement control unit 8 is performed in response to a detection result that the driver's seat 2 has moved forward from a predetermined rear position by the position detection unit 6 after the forward movement command.

[Operation procedure]
The operation procedure of the moving mechanism 7 by the movement control unit 8 will be described in order.

(Child seat advanced by moving mechanism)
First, when the child seat 4 is mounted on the rear seat 3 on the passenger seat side, the mounting detector 5 detects that the child seat 4 is mounted on the rear seat 3. The movement control unit 8 receives the detection result of the mounting detection unit 5. In this state, when the driver's seat 2 is moved backward to a predetermined rear position, the position detector 6 detects that the driver's seat 2 has moved to a predetermined rear position. The movement control unit 8 receives the detection result of the position detection unit 6. At this time, the movement control unit 8 receives the detection results of both the mounting detection unit 5 and the position detection unit 6 and instructs the movement mechanism 7 to advance the child seat 4. Then, the child seat 4 moves forward by the moving mechanism 7.

(The child seat is moved backward by the moving mechanism)
When the driver's seat 2 moves forward from a predetermined rear position with the child seat 4 moving forward, the position detector 6 detects that the driver's seat 2 has moved forward from the predetermined rear position. The movement control unit 8 receives the detection result of the position detection unit 6. At this time, the movement control unit 8 instructs the moving mechanism 7 to move the child seat 4 backward. Then, the child seat 4 is moved backward by the moving mechanism 7 and returned to the original position before the forward movement.

[Function and effect]
The vehicle seat structure according to the first embodiment described above can be easily accessed from the driver's seat 2 to the child seat 4. When the driver's seat 2 is moved to a predetermined rear position while the child seat 4 is fixed to the rear seat 3 on the passenger seat side, a moving mechanism 7 that moves the child seat 4 forward is provided so that the driver's seat 2 and the child seat 4 can move forward. This is because the distance between them can be reduced. Therefore, it is easy for the driver to put the child on the child seat 4 of the rear seat 3 on the passenger seat side and to lower the child seat 4 on the driver seat 2. Therefore, since the driver can get on and off the car from the driver's seat door together with the child, it is difficult for the driver and the child to get on and off the vehicle. That is, when the driver and the child get on, the driver does not need to go around the vehicle to the driver seat door after the driver puts the child on the child seat 4 from the rear seat door on the passenger side outside the vehicle. When the child and the child get off, there is no need for the driver to get out of the driver's seat door and go around the vehicle to the rear seat door on the passenger side.

  The present invention is not limited to these exemplifications, but is defined by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims. The vehicle seat structure 1A described above can be similarly used in a left-hand drive automobile. In the left-hand drive automobile, the left and right in FIG. 1 are reversed.

  Further, the length of the rail of the driver's seat can be set to a length that allows the driver's seat to slide to the extent that it touches the rear seat when the driver's seat is moved backward. In that case, when the driver's seat is moved backward to the rear end of the sliding movable range and the child seat of the rear seat on the passenger seat is advanced, the distance between the driver's seat and the child seat can be further reduced. Children's child seats are particularly easy to get on and off.

  Further, the passenger seat may be constituted by a power seat, and the passenger seat may be advanced as the rear seat on the passenger seat side advances. If it does so, since the space | interval between the backseat on the passenger's seat side and a passenger seat is hard to become narrow, it is easy to get on and off the child seat of the child from a driver's seat. At this time, the passenger seat preferably includes an occupant detection sensor that detects the presence or absence of an occupant in the passenger seat. Examples of the occupant detection sensor include a load sensor. The installation detection unit detects that the child seat is mounted on the rear seat on the passenger seat side, the position detection unit detects that the driver's seat has moved to a predetermined rear position, and the passenger detection sensor detects that the passenger seat is in the passenger seat. When it is detected that the passenger is not seated, the rear seat on the passenger seat side is advanced by the movement control unit and the passenger seat is advanced. Thereafter, when the position detection unit detects that the driver's seat has moved forward from a predetermined rear position, the rear seat on the passenger seat side is moved backward and the passenger seat is moved backward by the movement control unit.

  The vehicle seat structure of the present invention can be suitably used for an automobile in which it is desired to easily access the child seat on the rear seat on the passenger seat side from the driver seat.
