  However, in the above-described seat device, the number of movable devices is increasing in order to achieve a state according to the user's preference. For this reason, the number of motors required to move the movable device is increasing, and the number of switches for moving the motor is increasing. As described above, the number of movable devices increases, the number of motors for moving the movable devices increases, and as a result, the number of switches increases, which complicates the operation and makes it difficult for the user to operate.

  The present invention has been made in view of the above-described conventional situation, and it is an object to be solved to provide a seat device that can be easily operated in accordance with a user's preference.

  As a result of diligent research to solve the above-mentioned problems, the inventors have reduced the number of switches as much as possible, enabling the operation of an increasing motor with the reduced number of switches, and driving an increasing number of movable devices. Thus, the present invention has been completed.

  That is, the technical means taken in the present invention to solve the above-mentioned problems are as described in claim 1, wherein a plurality of motors, a movable device driven corresponding to each of the motors, and the motors are provided. In the seat device comprising a switch for controlling the operation of the switch, the motor to be operated is selected based on the movement amount of the switch, and the rotation direction of the selected motor is determined based on the movement direction of the switch It is characterized by that.

  The technical means taken in the present invention is characterized in that the movement amount of the switch can be adjusted in a plurality of stages.

  Further, the technical means taken in the present invention is characterized in that, as described in claim 3, the motor is controlled by a pulse width modulation system.

  According to the technical means of the present invention, the operation of the non-selected motor is controlled by the pulse width modulation method when the motor to be operated is selected based on the movement amount of the switch. It is characterized by doing.

  According to the first aspect of the present invention, the motor to be operated is selected based on the movement amount of the switch. For this reason, even if the number of switches is small, the number of operable motors can be increased by changing the movement amount of the switches. Further, the rotation direction of the selected motor is determined based on the moving direction of the switch. For this reason, even if the number of switches is small, the rotational direction of the motor can be changed by changing the moving direction. The motor that operates according to such selection drives the movable device, whereby the seat device can be brought into a user's favorite state. That is, since the movable device of the seat device can be driven with a small number of switches, the user can easily operate without complicating the operation.

  Therefore, the seat device of the present invention can be easily operated in a state according to the user's preference.

  According to the second aspect of the present invention, since the movement amount of the switch can be adjusted in a plurality of stages, the operation and rotation of a large number of motors can be selected. Therefore, by increasing the number of options and operating the motor in this way, it is possible to increase the number of movable devices that are driven based on the motor.

  Furthermore, according to the third aspect of the invention, since the motor is controlled by the pulse width modulation method, the motor can be slowly started. For this reason, instantaneous operation and stop of the motor can be suppressed based on the switches in the middle of the movement in a plurality of stages. In this way, if the motor is prevented from being driven or stopped instantaneously, the cause of failure caused by instantaneously moving or stopping the movable device can be reduced.

  According to the fourth aspect of the present invention, when the switch moves in a plurality of stages, the operation of the motor is controlled by pulse width modulation during the movement of the switch or in the change of the moving direction. It is possible to suppress the operation of the motor so as to slow start. That is, when the switch is moved to a position of a plurality of stages or the direction of movement of the switch is changed, instantaneous operation of the non-selected motor can be prevented at each stage during the movement of the switch. For this reason, vibrations that occur when the motor is operated or stopped instantaneously are less likely to occur, so that discomfort given to the user can be reduced.

  As described above, the movable device is not limited to the headrest device 40a and the like described above, and the motor M1 and the like provided in the headrest device 40a and the like are not limited to those described above.

  Such a seat device is provided, for example, in a vehicle interior (not shown), and the motors M1 to M11 described above are operated by the switch 5 shown in FIG. The switch 5 is not only attached to the side surface of the seat cushion member 30 of the seat device as shown in FIG. 1, but may be provided in a door, a center console, or the like (not shown) in the vehicle interior, for example. The switch 5 is connected to a control device (not shown), and each motor (for example, M1 to M6) described above is connected to the control device. In such a control device, the operations of the motors M1 to M11 are controlled by a pulse width modulation method (hereinafter referred to as PWM).

  As shown in FIG. 3, the switch 5 provided in the seat device is, for example, circular, and can be moved in two stages in the left-right direction, the up-down direction, and the left-right rotation direction.

  Hereinafter, an example of a motor that is operated when the switch 5 is operated and a movable device that is driven will be described.

  For example, the motor M10 (shown in FIG. 2) of the cushion length extension / contraction device 40h (shown in FIG. 2) can be operated by moving the switch 5 by one step A in the left-right direction. Then, the cushion length extending / contracting device 40h is driven by the operation of the motor M10, and the seat cushion member 30 shown in FIG. Also, the motor M11 (shown in FIG. 2) of the seat slide device 40i shown in FIG. 1 can be operated by moving the switch 5 shown in FIG. Then, the seat slide device 40i is driven by the operation of the motor M11, and the seat cushion member 30 is slid back and forth.

  Further, the motor M9 (shown in FIG. 2) of the tilt device 40g (shown in FIG. 2) can be operated by moving the switch 5 shown in FIG. 3 one step in the vertical direction. Then, the tilting device 40g is driven by the operation of the motor M9, and the front end of the seating surface 30a of the seat cushion member 30 shown in FIG. Further, the motor M8 (shown in FIG. 2) of the lifter device 40f (shown in FIG. 2) can be operated by moving the switch 5 shown in FIG. 3 in two steps in the vertical direction. Then, the lifter device 40f is driven by the operation of the motor M8, and the entire seating surface 30a of the seat cushion member 30 shown in FIG. 1 is moved up and down.

  Furthermore, the motor M3 (shown in FIG. 2) of the folding device 40b (shown in FIG. 2) can be operated by moving the switch 5 shown in FIG. Then, the folding device 40b is driven by the operation of the motor M3, and the upper end side of the seat back member 20 shown in FIG. 1 is folded. Further, the motor M7 (shown in FIG. 2) of the reclining device 40e shown in FIG. 1 can be operated by moving the switch 5 shown in FIG. And the reclining device 40e will be driven by the action | operation of the motor M11, and the whole seat back member 20 shown in FIG. 1 will be tilted back and forth.

  As described above, the motors M10, M11, M9, M8, M3, and M7 (shown in FIG. 2) to be operated are selected based on the movement amount of one switch 5 shown in FIG. The driving of the movable devices 40h, 40i, 40g, 40f, 40b, and 40e (shown in FIG. 2) can be selected. Further, the rotational direction of the selected motors M10, M11, M9, M8, M3, and M7 is determined by the moving direction of one switch 5, and for example, the above-described six types of movable devices 40h, 40i, 40g, The drive directions of 40f, 40b, and 40e can be determined.

  As described above, in the seat device according to the embodiment, if the number of switches 5 is increased or another change-over switch is provided, it is possible to select driving of all the movable devices 40a to 40i described above.

  Regardless of the shape described above, the switch 5 may employ various shapes such as a rectangular shape as shown in FIG. 4 and a diamond shape as shown in FIG.

  Here, if the switch having the rhombus shape shown in FIG. 5 is used as the switch 5, the movement is divided into the left-right direction, the up-down direction, the left-right rotation direction, the right diagonally upward and left diagonally downward direction, the left diagonally upward and right diagonally downward direction. It becomes easy to determine the direction. If the switch 5 can be moved in two steps in each direction, each of the left and right directions, the up and down directions, the left and right rotation directions, the right diagonally upper and left diagonally down directions, the left diagonally upward and right diagonally downward directions. Two types of movable devices can be selected. For this reason, a total of 10 types of movable devices can be selected. In this case, as shown in FIG. 2, the headrest device 40a, the folding device 40b, the lumbar port device 40c, the side support device 40d, the reclining device 40e, the lifter device 40f, the tilt device 40g, as described above, can be performed by one switch 5. It is possible to drive all the movable devices of the cushion length expansion / contraction device 40h and the seat slide device 40i. Further, even if a movable device (for example, an ottoman device) not described above is provided in the seat device, it can be driven by the switch 5 described above. Note that the switch 5 can change the movement amount in a plurality of stages.

  If the predetermined motors M1 to M11 are controlled by PWM, the motors M1 to M11 can be started slowly. For this reason, the instantaneous operation | movement and stop of the motors M1-11 can be suppressed based on the switch 5 in the middle of the movement of several steps. In this way, if the motors M1 to M11 are prevented from being operated or stopped instantaneously, the cause of failure due to the momentary movement or stop of the movable devices 40a to i can be reduced.

  In particular, when the switch 5 moves in a plurality of stages (or two stages), if the operation of the non-selected motor is controlled by the PWM of the control device during the movement of the switch 5, the operation of the non-selected motor is thrown. It can be suppressed to start. At this time, the operation of the selected motor is released from the PWM control. That is, when the switch 5 is moved to a position of a plurality of stages (or two stages), instantaneous operation of the non-selected motor can be prevented at each stage during the movement of the switch 5. For this reason, vibrations that occur when the motor is operated or stopped instantaneously are less likely to occur, so that discomfort given to the user can be reduced. Then, only the selected motor operates instantaneously.

  In the seat device configured as described above, the motors M1 to M11 to be operated are selected according to the movement amount of the switch 5. For this reason, even if it is a small number of switches 5, if the movement amount is changed, the number of operable motors M1 to M11 can be increased. Further, the rotation direction of the selected motors M1 to M11 is selected according to the moving direction of the switch 5. For this reason, even if it is a small number of switches 5, if the movement direction is changed, the rotation direction of the motors M1 to M11 can be determined. By driving the movable devices 40a to 40i based on the motors M1 to 11 operated by such selection, the seat device can be brought into a user's favorite state. That is, since the movable devices 40a to 40i of the seat device can be driven with a small number of switches 5, the user can easily operate without complicating the operation.

  Therefore, the seat device according to the embodiment can be easily operated in a state according to the user's preference.

  Further, if the movement amount of the switch 5 can be adjusted in a plurality of stages, the operation and rotation of a large number of motors can be selected. Therefore, by increasing the number of options and operating the motor in this way, it is possible to further increase the number of movable devices that are driven based on the operation of the motor.
