It's the location. The unfolded position is a position where the ottoman part 12 is used (to be easy to understand, a position where the lower legs of the occupant can be supported), and when the ottoman part 12 protrudes forward from the front end of the seat cushion part 11. This is the position of

Furthermore, the length of the ottoman portion 12 from the base end supported by the seat cushion portion 11 to the free end portion (hereinafter referred to as the entire length) is expandable and contractible. In other words, the ottoman portion 12 is configured such that the total length is the shortest when it is in the storage position, and the total length gradually increases as it approaches the deployed position.

Further, in this embodiment, the headrest section 13 can be moved up and down with respect to the seat back section 10 by a headrest moving mechanism (not shown). That is, in this embodiment, it is possible to change the position where the occupant's head is supported in accordance with the movement of the headrest part 13 by the headrest movement mechanism.

The seat support section 19 is a device that supports the vehicle seat S from below, and is attached to the lower part of the seat cushion section 11. Specifically, the seat support section 19 is configured by covering a frame member that connects the vehicle seat S, the seat slide mechanism 20, and the seat rotation mechanism 24 with a cover member. Note that an ECU 40 as a control unit that controls each part of the vehicle seat S is housed inside the seat support part 19. Of course, the ECU 40 is not limited to the seat support section 19, and may be housed inside the seat back section 10, the seat cushion section 11, etc., or may be attached externally to the vehicle seat S.

The seat slide mechanism 20 is a mechanism for sliding the vehicle seat S with respect to the vehicle body floor F in the front-rear direction and the left-right direction. The seat slide mechanism 20 includes an upper rail 21, a lower rail 22, and a slide motor for sliding the upper rail 21 with respect to the lower rail 22. A Hall IC is also attached to the slide motor, and a pulse is output every time the motor rotates once.

Here, by operating the above-mentioned slide motor to slide the upper rail 21 back and forth or left and right with respect to the lower rail 22, the vehicle seat S, that is, the seat back portion 10, the seat cushion portion 11, the headrest portion 13, and the The ottoman portion 12 can be integrally moved forward and backward or left and right with respect to the vehicle body floor F.

The seat rotation mechanism 24 is a mechanism for rotating the vehicle seat S with respect to the vehicle body floor F around an axis in the vertical direction. The seat rotation mechanism 24 includes a seat rotation motor. A Hall IC is also attached to the seat rotation motor, and a pulse is output every time the motor rotates once. The pulses are received by the ECU 40, thereby making it possible to measure the rotation angle of the vehicle seat S with respect to the moving direction of the vehicle.

The vehicle seat S also includes an operation switch 25. The operation switch 25 is an operation section that is provided on the side of the seat cushion section 11 of the vehicle seat S and is used to instruct the posture change of the vehicle seat S. For example, the operation switch 25 may include a first switch for changing the vehicle seat S from an upright position to a reclining position, and a second switch for changing the vehicle seat S from a reclining position to an upright position.

The ECU 40 is a control unit that controls the reclining mechanism 15, tilt mechanism 16, seat slide mechanism 20, seat rotation mechanism 24, projector 30, and projector movable mechanism 32 described above. Further, pulses are received from motors provided in the reclining mechanism 15, the tilt mechanism 16, the seat slide mechanism 20, the seat rotation mechanism 24, and the projector movable mechanism 32 (hereinafter sometimes referred to collectively as the movable mechanism). As shown in FIG. 3, the ECU 40 includes a processor 41, a memory 42, and an input/output interface 43.

The processor 41 executes various arithmetic processing based on programs and data stored in the memory 42 and signals received from each device connected via the input/output interface 43, and also controls each part of the display system 1. It is a central processing unit. The memory 42 is, for example, a semiconductor memory, and in addition to storing various programs and data, it also functions as a work memory for the processor 41. The input/output interface 43 is connected to the reclining mechanism 15, tilt mechanism 16, seat slide mechanism 20, seat rotation mechanism 24, projector 30, projector movable mechanism 32, and operation switch 25, and communicates with each device.

Further, as described above, the vehicle seat S is provided with an operation switch 25 for changing the posture. The operation switch 25 is a push button type switch provided on the door or armrest of the vehicle, and is operated by an occupant seated on the vehicle seat S to change the posture of the seat back portion 10 and the like.
In this embodiment, the posture of the vehicle seat S is switched by turning the operation switch 25 ON/OFF, but while the operation switch 25 is pressed down, the reclining mechanism 15 operates and the seat back section 10 moves. The slope may be gradually inclined to suit the preference of the occupant H.
Further, a projection start switch 34 is provided. By pressing the projection start switch 34, the projector 30 starts projecting an image. At this time, the ECU 40 determines the state of the vehicle seat S, for example, whether it is in a reclining position or in an upright position. Specifically, the ECU 40 obtains the inclination angle α of the seat back portion 10, the inclination angle β of the seat cushion portion, and the height h of the seat cushion portion 11 based on information on the rotation speed of the motor of each movable mechanism. From this information, the projection angle θ (the angle θ between the vehicle floor F and the projection axis 33) at which the projector 30 projects the image is calculated.

At this time, the projection angle θ of the projector 30 is set based on a correspondence table in which the inclination angle α and the optimum projection angle θ of the projector corresponding to the inclination angle α are recorded, as shown in Table 1, for example. For example, when the tilt angle is 75 degrees, the projection angle θ of the projector is set to 15 degrees.
Note that the projection angle θ is basically determined so that the image is located beyond the line of sight of the occupant H when the occupant H is seated. Therefore, for example, in a standing position as shown in FIG. 1, an image may be projected onto the front seat S1 in front, and in a reclining position as shown in FIG. may be projected.
Based on the value of the set projection angle θ, the ECU 40 moves the projector 30 or the projector movable mechanism 32 to set the projector at an optimal projection angle, and determines the display position of the image 31.

In the above example, the projection angle θ was determined based on the correspondence table between the inclination angle α and the projection angle θ, but the projection angle θ is determined by the inclination angle β of the seat cushion portion 11 and the height h of the seat cushion. A correspondence table including .theta. may be determined in advance, and the projection angle .theta. of the projector 30 may be calculated based on the correspondence table. Furthermore, the projection angle θ may be calculated based on the position and rotation angle of the entire vehicle seat S to determine the display position of the image. At this time, the entire projector 30 may be rotated not only in the vertical direction but also in the horizontal direction.

Hereinafter, with reference to FIG. 5, the processing of the display system 1 from when the projection start switch 34 is pressed until the projector 30 determines the display position of the image 31 will be described.

First, when the occupant H presses the projection start switch 34, the ECU 40 starts the process of projecting an image using the projector 30. Then, the state of the vehicle seat S and the state of the projection angle θ of the projector 30 are acquired (S101).

Next, it is determined whether the state of the vehicle seat S has changed from the state at the time when the projection by the projector 30 was completed last time (S102). If the state of the vehicle seat S has not changed, for example, if it was not changed in the upright state last time and is in the upright state this time as well (in the case of No), it is necessary to change the projection angle θ of the projector 30. There is no difference, and the process of changing the projection angle θ of the projector 30 ends.

In step 102, when the ECU 40 determines that there has been a change in the state of the vehicle seat S (Yes in step 102), the ECU 40 stores information based on the state of the vehicle seat S after the change, for example, the inclination angle α. Using the correspondence table stored in 42, the optimum projection angle θ of the projector 30 is determined (S103).

Next, the ECU 40 uses the projector 30 or the projector movable mechanism 32 to operate or move the projector 30 so that the projection angle θ of the projector 30 becomes the angle determined in step 103 (S104). By using the ECU 40 in this way, the projection angle θ of the projector 30 can be set according to the state of the vehicle seat S, and the display position of the image 31 can be determined.

Next, another example of the display system 601 will be described using FIGS. 6 and 7. In the display system 1 shown in FIGS. 1 to 3, the projector 30 is arranged on the center console 5, but in the display system 601 shown in FIG. 6, the projector 630 is mounted on the headrest section 613 where the occupant H is seated. As shown in FIG. 7, the projection unit 635 of the projector 630 changes the projection angle θ by rotating about an axis in the width direction. By providing the headrest portion 613 with a projector 630, images are displayed on the roof inside the vehicle. Since the structure other than the structure of the projector 630 is the same as that of the display system 1 shown in FIG. 1, detailed explanation of the other structures will be omitted.

Next, another example of a display system 801 will be described using FIG. 8. In the display system 1 shown in FIGS. 1 to 3, the projector 30 is placed in the center console 5, but in the display system 801 shown in FIG. It is provided in the seat back portion 10 of the front seat S1. When the rear seat S2 is in the upright position, the projector 830 installed on the seat back section 10 of the front seat S1 may project onto the headrest section 13 of the front seat S1. When the vehicle seat S is in the reclined position, the projector 830 may project a projected image onto the screen 4 provided on the roof 3.

In the display system 1 shown in this embodiment, the projected image is projected on the back of the seat back of the front seat S1 or on the roof, but the position where the image is projected is not limited to this, and may be on a window or door. good.
Further, although the projector 30 was installed in the center console 5, the headrest part 13, and the seat back part 10, the location where the projector 30 is installed is not limited to this, and it may be installed in the armrest of the vehicle seat S. good.

A plurality of projectors may be installed inside the vehicle, and the ECU 40 may set a vehicle seat that follows each projector.

In the above embodiment, a display system used in a car was explained as a specific example, but the display system of the present application can be installed in a train, a bus, etc. without being particularly limited, and can also be installed in an airplane, a ship, etc. You can also use
