The explanation will be as follows based on the figures.

Incidentally, portions having the same features as those in FIG. 7 and subsequent figures will be described using the same reference numerals.

The illustrated embodiment is a system for easily operating a television while changing the seating direction in a predetermined number of seating seats provided in the passenger seats of a vehicle such as a Shinkansen. In the embodiment shown in FIGS. 1 to 4,
On the floor 12 of the cabin, a predetermined number of seats are arranged in a predetermined manner through sleeve bush type bearings 2 in the form of seating seats 1, 1, etc., which can freely change direction forward and backward as the direction of travel of the vehicle changes. , each backrest 9', and the end wall 9, personal type LCD televisions 3', 3'... are arranged at a predetermined angle for easy viewing, and the lower part of the seat cushion of each sitting seat 1 In this embodiment, an operation signal output unit 16 for performing operation using wireless infrared rays is provided.
The television 3' is connected to an operation panel 11 provided at 0 through a lead wire 17 to operate the television 3'.

An operation signal output section 16 is provided at the bottom of the seat cushion, and in response to the transmitted signal, an operation signal input section 18 at the bottom of the seat cushion of the front seat 1 also uses wireless infrared rays.
is provided to receive the operation signal via the signal path 19 of the infrared operation signal beam from the operation signal output section 16, and is connected to the television 3' via a lead wire 20.

As shown in FIGS. 3 and 4, a positioning projection 11 is provided at one location in the circumferential direction of the rotatable sleeve bush type bearing 2 of each seating seat 1 to correspond to the rotational movement of the sleeve bush type bearing 2. The positioning notch 15 of the positioning bracket 14 is pressed from the floor 12 by a pair of elastic springs 13, 13. Depending on the change in the direction of travel at the terminal station, the seating direction is changed via the sleeve bushing type bearing 2 in the same way as in the conventional system.
Even when the direction is changed by 180 degrees, the directional posture of the seating seat 1 before and after the direction change does not change, and the positioning projection 11 engages with the positioning notch 15 to ensure that each operation signal output section 16 ensures that the operating signal in the signal path 19 is transmitted in the direction of the corresponding operating signal input 18 .

The image is received by the TV 3' via the lead wire 20 and is transmitted to the TV 3' to generate an image and sound, and the passenger 8 can see the image on the TV 3' and listen to the sound through earphones (not shown). .

Therefore, when the train reaches the terminal station and performs the prescribed maintenance, the direction of travel is reversed and the train departs, as in the conventional system, the seating direction of each seating seat 1 is changed using the sleeve bushing. At this time, the positioning projection 11 of the sleeve bush type bearing 2 rotates integrally to change the posture of the positioning bracket 14 against the elastic springs 13, 13, and the positioning is performed via the sleeve bush type bearing 2. The operation signal output section 16 of each seating seat 1 is positioned at the notch 15, and therefore, after the seating direction is changed, the operation signal output section 16 of each seating seat 1 is
accurately directed to the corresponding operation signal input section 18,
As a result, even in the opposite direction of travel, by operating the hand control panel 11' of the armrest 10 on the seat 1, the image signal and audio signal of the facing TV 3' can be transmitted in a comfortable posture.
It can be done accurately.

Of course, in this embodiment, as shown in FIGS. 1 and 2, the television 3' on the end wall 9 is not used in the opposite direction of travel.

Therefore, in this embodiment, the signal path for the operation signal between the operation signal output section 16 and the operation signal input section 18 is performed by an infrared system, but it is also possible to use an ultrasonic system as a wireless system. Of course, this is just a matter of design change.

In the embodiment shown in FIGS. 5 and 6, the operation signal is transmitted and received by a wireless system in the above-mentioned embodiment, but the transmission and reception is performed by a wired system. ’ positioning projection 1
1 and the positioning notch 15, the connectors 21 and 21 between the two come into contact with each other in a metal-like manner, and the operation signal from the operation panel 11' is transmitted and received in a wired manner to the TV via the lead wire 20. Although the operation 3' is performed, the effect obtained is no different from the above-mentioned embodiment.

The positioning projection 11 and the positioning notch 15 each constitute a seating direction fixing device.

In this embodiment, the operation signal output section 16
and the operation signal input section 18 replace the connector 21 described above.

The difference between the above-mentioned embodiments is whether the operation signal is transmitted and received in the signal path by a wireless method or by a wired method.

It goes without saying that the embodiments of the invention of this application are not limited to the above-mentioned embodiments, and the television to be used is not limited to a liquid crystal television, but may also be a cathode ray tube type television, and the target passenger seats are those on Shinkansen trains, etc. It goes without saying that the invention is applicable not only to passenger seats on trains, but also to passenger seats on passenger ships and the like.

<Effects of the Invention> As described above, according to the invention of this application, basically, even when changing the seating direction due to a change in the direction of travel at the terminal station of the Shinkansen, etc., each seat is provided with a Since the channel switching and volume control operations on a TV such as an LCD TV are performed using the operation panel installed on the armrest, there is an advantage that the operation can be done smoothly without disturbing the sitting posture. Even if the sitting direction of the seat is changed, various operations on the television corresponding to the front can be performed reliably in a comfortable posture on the operation panel of the armrest.

Therefore, even if the seating direction of the seating seat is changed due to a change in the traveling direction of the train, etc., the operation signal output section and the operation signal input section provided on the lower side of the seat cushion of the seating seat can be used to control both directions. Since operation signals are transmitted and received by wireless or wired methods through the signal path between the seats, there is an advantage that operations can be performed regardless of the sitting posture of the passenger in the seat. .

In addition, in the case of a wireless system, there is no need for connectors, cables, etc., the structure is simple in terms of equipment, and there are advantages in terms of cost.

In addition, in the case of the wired method, since metal touch-like connection is performed using a connector through positioning using a positioning and seating direction fixing device such as a sleeve bushing type bearing, the effect is that operation signals can be transmitted and received reliably. There is.
