BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. Hereinafter, Embodiment 1 of the present invention will be described with reference to FIG. FIG. 1 is a rear view of a seat, 1 is a backrest view, 2 is an armrest, and 3 is a mounting leg of the seat, which maintains an appropriate height between the seat and the floor surface 4. Reference numeral 5 denotes a radiating surface for performing radiant air conditioning from the back of the seat back to the rear seat. Reference numeral 6 denotes a folding simple table, and reference numeral 7 denotes a net-shaped magazine pocket. Reference numeral 8 denotes an operation panel installed on the upper surface of the armrest 2 for starting and stopping the radiation surface and adjusting the temperature.

The passenger controls the operation panel 8 to start and stop air conditioning by radiation from the radiation surface 5 and to adjust the temperature of the radiation surface 5. Operation panel 8
The operation of the radiating surface and the surface temperature are controlled based on the operation information input to the occupant, and the radiant air conditioning is performed on the passenger.

With this configuration, the passengers can enjoy the air-conditioning by radiation, so that there is no discomfort due to the discharge air, and since the operation panel can freely control the start / stop of the radiation surface and the surface temperature, the passengers can be individually controlled. Individual differences in thermal sensation can be corrected, and individual differences between adjacent seats and loss due to mixing such as discharged air can be reduced.

In the present invention, the heat source of the radiation surface is not limited, and the same effect can be obtained as long as the radiation surface temperature can be adjusted such as air, refrigerant, and water.

The air-conditioning control mechanism is provided in parallel with the main air-conditioning means for air-conditioning the entire cabin, and the base air-conditioning load is performed by the main air-conditioning means.

Embodiment 2 Embodiment 2 of the present invention
Will be described with reference to FIG. FIG. 2 shows an embodiment in which the seat is a face-to-face seat, and the same reference numerals as those in FIG. 1 denote the same members. Reference numeral 9 denotes a ceiling surface or a lower surface of a cargo shelf, and reference numeral 10 denotes a radiation surface. In the first embodiment, since the air-conditioning cannot be performed in the case of the facing seat on the radiation surface of the seat backrest portion, the ceiling surface or the radiation surface provided on the ceiling portion such as the lower surface of the load shelf as shown in FIG. Radiation air conditioning is performed from the ceiling direction on the lower surface of the load shelf. In this case, the radiation surface 5 of the backrest is stopped, and only the radiation surface on the ceiling surface or the lower surface of the shelf is operated.

In the case of a face-to-face seat, the air-conditioning effect of the radiating surface on the back of the seat cannot be enjoyed. The operation panel 8 controls the start / stop of air conditioning by ceiling radiation and the adjustment of the radiation surface temperature. Based on the operation information input to the operation panel 8, the operation of the radiation surface 10 and the surface temperature are controlled, and radiation air conditioning is performed on the passenger.

With this configuration, even when the seat is a face-to-face seat, the passenger can enjoy the air-conditioning by the radiation without discomfort, and the individual difference can be corrected. Even if there is, it is possible to cause each to perform an appropriate air-conditioning action.

Embodiment 3 Embodiment 3 of the present invention will be described with reference to FIG. FIG. 3 is a rear view of the seat, and FIG.
The same reference numerals indicate the same members. Embodiment 1
In this embodiment, the number of radiation surfaces is required by the number of all seats. Further, in the second embodiment, since each of the seats has a radiation surface provided on the ceiling portion and a radiation surface of the backrest portion, the radiation surface is required to be twice the number of seats. . One of the major factors in the actual cabin environment where the environment differs for each seat position is considered to be the presence or absence of solar radiation. Therefore, in this embodiment, the entire cabin is controlled by the main air-conditioning means, and a radiation surface 5 for performing radiation air-conditioning is provided only on window-side seats, which are considered to be particularly affected by solar radiation.

The passenger controls the operation panel 8 to start and stop air conditioning by radiation and adjust the radiation surface temperature. The operation of the radiation surface 5 and the surface temperature are controlled based on the operation information input to the operation panel 8, and the radiation air conditioning is performed particularly for the passengers on the window side where the influence of the solar radiation is expected to be large.

With such a configuration, it is possible to cope with a difference in environment due to solar radiation, which is considered to have a particularly large effect on the environment in the passenger compartment, by providing a smaller radiation surface than in the first and second embodiments.

[0021]

According to the first aspect of the present invention, there is no discomfort due to the discharged air, and passengers can individually correct individual differences in thermal sensation, and furthermore, individual differences between adjacent seats can be corrected. Such mixing loss can also be reduced.

According to the second aspect of the present invention, even when the seats are face-to-face seats, there is no discomfort due to the discharged air, and passengers can individually correct individual differences in thermal sensation. The effect of reducing the individual difference and the loss due to mixing such as the discharge air can be similarly exerted.

According to the third aspect, it is possible to cope with a difference in environment due to solar radiation with a smaller radiation surface.
