Description

  The present invention relates to a rotary storage seat device in which a rear seat of an automobile can be stored on a vehicle floor or the like, and more particularly to a rotary storage seat device that performs storage operation electrically.

  Some vehicles with a large interior space such as a one-box car can accommodate various seat arrangements to store the second and third rows of seats in the lower part of the vehicle floor and secure a large cargo space when not needed. . In addition, in this rotational storage operation, in the third row of seats (third seats), the seat back is moved forward and superimposed on the seat cushion, and the seat back is folded and the entire seat device is rotated backward to the vehicle floor. What is accommodated in the provided recessed part is known (for example, refer patent document 1).

  The automatic rotating storage seat system (10) for a vehicle described in Patent Literature 1 includes a seat back forward tilting mechanism and a seat swinging mechanism.

  The seat back forward tilt mechanism includes a reclining mechanism portion (14) attached to a seat back frame (13) which is a frame of the seat back (11), and a reclining lock actuator portion (15). Alternatively, it is a mechanism for causing the seat back (11) to move forward on the seat cushion (12) side so as to overlap the seat cushion (12).

  The seat swing mechanism is composed of a cushion lock mechanism portion (16) and a storage unit mechanism portion (17). The seat back (11) and the seat cushion (12) are swung on the vehicle body side. The mechanism is housed in a recess (not shown) formed on the floor behind the seat.

  The seat back forward tilt mechanism and the seat swing mechanism can be operated by an operation switch disposed behind the seat, and the seat can be stored and returned.

  However, in the conventional rotary storage seat device described above, the seat cushions (12) of two seats arranged in parallel are of a bench seat type in which two seats are connected, and cannot be stored independently one by one when stored. .

  Also, to store each of the two seats, the seat cushion is an independent seat, and two motors are required to drive each of them, and it is also necessary to install wiring for the power supply and the space for installing these motors become.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a rotary storage sheet device that can easily store two sheets electrically.

  In order to solve the above-described problem, in the rotary storage seat device according to claim 1, the rotary storage seat device stores the seat in a storage space provided on the vehicle floor, and a plurality of seats are installed in parallel. A rotation shaft that is rotatably supported independently, a drive device that rotates the seat around the rotation shaft between a seating position and a storage position, and a driving force of the drive device is transmitted between adjacent seats, or A technical feature is that a clutch capable of switching non-transmission is provided.

  According to a second aspect of the present invention, in addition to the feature of the first aspect, the driving device includes a motor, and the motor can be automatically stored by operating the motor. And

  According to the rotary storage seat device according to claim 1, the rotary storage seat device stores the seat in a storage space provided on the vehicle floor, and a plurality of seats are installed in parallel so that each can rotate independently. It is possible to switch between a supported rotating shaft, a driving device that rotates the seat around the rotating shaft between the seating position and the storage position, and transmission or non-transmission of the driving force of the driving device between adjacent seats. Since it is a rotating storage seat with a clutch, it is possible to rotate each seat by switching the driving force of the drive device with the clutch, and one seat is suitable for leaving a seated state for the passenger to sit Sheet arrangement can be provided.

  In addition to the effect of the first aspect, the rotary storage sheet device according to the second aspect includes the motor, and the motor can be automatically stored by operating the motor, so that the operation is easy. In addition, the form of the seat arrangement can be operated by remote switch operation.

  A rotary storage sheet device according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic view of a rotary storage sheet device 1 according to the present invention. FIG. 2 is a schematic view showing one operation of the rotary storage sheet device 1. FIG. 3 is a schematic view showing another operation of the rotary storage sheet device 1.

  The rotary storage seat device 1 includes, for example, at least a pair of seats 1a and 1b arranged in a third row of a vehicle, and a seat cushion 2 that can be rotated on a vehicle floor surface using shafts 11 and 11a as rotation axes. , 2a, seat backs 3 and 3a rotatably attached to the seat cushions 2 and 2a, and a drive device 4 that rotationally drives the shafts 11 and 11a.

  The seat backs 3 and 3a are connected to the seat cushions 2 and 2a via a known reclining device that can be fixed at an arbitrary angle, and are either an electric type driven by a motor or a manual type manually operated by an occupant. Is now equipped.

  The shafts 11 and 11a can rotate independently, and the seat 1b can be held in a seatable state even when the seat 1a is rotated and stored. In addition, an electromagnetic clutch 5 is provided between the shafts 11 and 11a. By supplying electric power to the electromagnetic clutch 5, the shafts 11 and 11a can be rotated in conjunction with each other.

  The drive device 4 is composed of a motor and a gear, and can be remotely operated by operating a switch (not shown) at a remote location such as a driver's seat. The drive device 4 is connected to one end of the shaft 11 and can rotate the shaft 11.

  Next, the operation of the rotary storage sheet device 1 having the above-described configuration will be described. First, the state normally used by the occupant is the state shown in FIG. 1, and each seat 1a, 1b can be adjusted to the seat back 3, 3a by a reclining device to fix the backrest at an arbitrary position. .

  When it is desired to rotate and store the seat on only one side, as shown in FIG. 2, the seat back 3 is moved forward so that the seat cushion 3 is flush with the seat cushion 2, and the shaft 11 is rotated by the driving device 4. Thus, the seat 1a is rotated from the seating position to the storage position and stored. At this time, since the driving force of the driving device 4 is not transmitted to the shaft 11a, the seat 1b can be rotated and stored manually. In the present invention, the seat 1a is electrically driven and the seat 1b is manually rotated from the seating position to the stowed position so that the seat 1b can be stowed. .

  Further, when it is desired to rotate and store one set of seats at the same time, as shown in FIG. 3, the seat backs 3 and 3a of the seats 1a and 1b are moved forward so as to face the seat cushions 2 and 2a. Then, power is supplied from the battery to the electromagnetic clutch 5 by a switch or the like to connect the shafts 11 and 11a by electromagnetic force so that the rotation of the shaft 11 is transmitted to the shaft 11a. Thereafter, the shafts 11 and 11a are rotated by the driving device 4, whereby the seats 1a and 1b are rotated from the seating state to the storage position and stored. By doing so, it becomes possible to simultaneously rotate and store a set of sheets on both the sheets 1a and 1b without using a driving device such as a motor.

  Further, the same effect can be obtained regardless of which side of the seats 1a and 1b the drive device 4 is provided, and the operation of the drive device 4 can be controlled by the state of the seat backs 3 and 3a.

  As described above, in the rotary storage sheet device according to the present invention, the shafts 11 and 11a for rotating and storing the sheets 1a and 1b can be connected by electromagnetic force by supplying electric power to the electromagnetic clutch 5, and the force of the drive device 4 can be connected. Can be communicated to both sheets. Therefore, it is not necessary to attach motors to both the sheets 1a and 1b, and it can be rotated and stored under the floor with a single driving device.

FIG. 1 is a schematic view of a rotary storage sheet device 1 according to the present invention. FIG. 2 is a schematic view showing one operation of the rotary storage sheet device 1. FIG. 3 is a schematic view showing another operation of the rotary storage sheet device 1.
