Description

The present invention relates to an in-vehicle entertainment system in which a video playback device and a display device are provided in a vehicle so that entertainment such as a DVD can be enjoyed.

  In recent years, with the price reduction of DVD playback devices and the conversion of movie software to DVD video, the penetration rate of DVD playback devices has increased rapidly. Also, in the car, the price of in-vehicle liquid crystal displays has been reduced, and the demand for watching movies taken in the passenger compartment and videos taken by individuals has increased due to the widespread use of RV cars that can be used by many passengers. ing. For this reason, in order to enable viewing in the rear seat, a rear entertainment system with a liquid crystal display attached to the center of the ceiling of the vehicle interior has begun to be set.

Also, an invention has been proposed in which an in-vehicle entertainment system is made detachable so that it can be used not only inside the vehicle but also outside the vehicle (for example, Patent Document 1).

  However, as a problem of the rear entertainment system of the ceiling-mounted liquid crystal display type that is generally popular, a liquid crystal display is installed in the center of the ceiling in the passenger compartment, so passengers in the passenger seat cannot enjoy and the screen from the seat position Are difficult to see and cannot be added after purchasing the vehicle.

  Furthermore, as in the entertainment system used in passenger airplanes, even if multiple displays are installed in front of each seat, only a small number of people get on the display, etc. It costs money and is not a good solution.

  Therefore, the present invention provides an in-vehicle entertainment system that can provide entertainment from any boarding position at a low price by providing a display unit that can be attached and detached.

  In an in-vehicle entertainment system configured by a display unit, a video playback device, and a wire harness connecting them, an adapter is installed in the front part of the passenger seat and the back part of the in-vehicle seat, and at least one of the adapters The above-mentioned problem is solved by providing an in-vehicle entertainment system characterized in that a display unit is attached to the vehicle.

  Regardless of whether you are in the passenger seat or the rear seat, you can watch a movie at the same time.

  Since it is not necessary to purchase an unnecessary display, the cost required for the in-car entertainment system can be reduced, and an entertainment system can be constructed according to the vehicle owner. In addition, if you purchase multiple displays, you can easily install according to the riding pattern. Furthermore, the number of displays can be increased as necessary.

  FIG. 1 is a schematic diagram of the in-car entertainment system 6. As is clear from this figure, the in-car entertainment system 6 installed in the vehicle 1 provided with the driver's seat 2, the passenger's seat 3, the right rear seat 4 and the left rear seat 5 includes the front of the passenger seat 3 and the driver seat 2, An adapter 10 is provided on the back surface of each of the passenger seat 3, the right rear seat 4, and the left rear seat 5. In the case where the air bag is provided in front of the passenger seat 3, it is desirable that the air bag is installed at a position that does not hinder the operation. The in-car entertainment system 6 is configured by being connected to the video reproduction device 9 via the adapter 10.

  By attaching the display unit 7 to at least one of these adapters 10, it is only necessary to install the display unit 7 according to the number of passengers, so that it is not necessary to purchase an unnecessary display, and the cost can be reduced. Furthermore, even if the number of passengers increases, it can be retrofitted, so it can be handled flexibly. Furthermore, since the display 11 is arranged in front of the seat, it has an advantage of easy viewing. As the display 11 to be used, a conventional display screen such as a liquid crystal screen or a CRT can be used.

  The contents of the in-car entertainment system 6 will be described in more detail. FIG. 2 is a system diagram of the in-car entertainment system 6. The in-car entertainment system 6 includes a relocation-compatible entertainment terminal 17, a video playback device 9, and a wire harness 8 that connects them. Each relocation-compatible entertainment terminal 17 includes a display unit 7 and an adapter 10.

  As the video playback device 9, a conventionally used device such as a DVD player can be used, and thereby movies and music stored on a DVD or the like can be played back. As information reproduced here, a video signal, a control signal, and an audio signal are sent to each relocation-compatible entertainment terminal 17.

  The display unit 7 included in each relocation-compatible entertainment terminal 17 is attached to the adapter 10. Each relocation-compatible entertainment terminal 17 receives a video signal, a control signal, and an audio signal via the adapter 10. The video signal is converted into a VIDEO signal by a conventional processing circuit 12 and displayed on the display 11. The audio signal is output from the speaker via the audio amplifier 15. The sound can be viewed using headphones or the like. The control signal is transmitted to the processing circuit 12 and the audio amplifier 15 via the control unit 13. Note that each relocation-compatible entertainment terminal 17 may be provided with an operation key 14 so that the operation signal is transmitted to the processing circuit 12, the audio amplifier 15, and the video reproduction device 9. This makes it possible to adjust the volume and change the channel at each terminal.

  The relocation-compatible entertainment terminal 17 has a power supply circuit 16 therein, and the terminal 17 is driven by being supplied with power from the power supply of the video playback device 9.
