Here, the design of the ventilation pipe is low in design cost and the manner of forming the ventilation duct 221 is simple and easy to implement, compared with the case where the ventilation duct 221 is opened in the seat back 2, such as a ventilation groove is dug in the seat back 2 body to form the ventilation duct 221.

Further, referring to fig. 1, 2 and 3, the decorative opening 21 is a through slot formed at an upper portion of the seat back 2, and at least one side wall of the through slot is provided with a ventilation hole for letting the air flow at the air inlet 222 flow out from the ventilation hole through the ventilation duct 221. Here, the decorative opening 21 is designed as a through slot, which is simple and inexpensive to construct. Preferably, the cross-sectional shape of the through-slot in the direction perpendicular to the length of the vehicle body is square, which is easier to process than the through-slot with circular, elliptical and irregular cross-sections, and the side wall of the through-slot is provided with a vent hole.

Here, the first ventilation holes 2111 and the second ventilation holes 2121 are respectively opened on two groove walls of the through groove that are opposite in the height direction of the seat back 2, so that an air flow toward the rear of the seat back 2 is formed at the air outlet.

The number of the first ventilation holes 2111 and the second ventilation holes 2121 and the shape of the ventilation holes are not limited, and preferably, one first ventilation hole 2111 and one second ventilation hole 2121 are formed in each of the first side wall 211 and the second side wall 212, and the first ventilation hole 2111 and the second ventilation hole 2121 are formed in a circular shape.

Further, referring to fig. 2, 4, 5 and 6, the seat back 2 is further provided therein with a first structural member 23 and a second structural member 24 disposed opposite to the first side wall 211 and the second side wall 212, respectively; in fig. 2, fig. 3, and fig. 6, the arrow directions each represent a schematic flow direction of the air flow, the first structural member 23, the first side wall 211, and at least part of the inner wall of the seat back 2 enclose a first air duct b1, and an air outlet direction of the first air duct b1 faces the first ventilation hole 2111, so as to guide the air flow at the air outlet end of the ventilation pipe to flow out from the first ventilation hole 2111; the second structural member 24, the second side wall 212 and at least part of the inner wall of the seat back 2 enclose a second air duct b2, and the air outlet direction of the second air duct b2 faces the second air vent 2121, so as to guide the air flow at the air outlet end of the ventilation pipe to flow out of the second air vent 2121.

The temperature sensor 252 is added at the rear of the seat, so that the temperature of the area where the rear passenger of the vehicle is located can be monitored in real time, the driving member 251 receives a temperature signal transmitted by the temperature, and the vehicle controller controls the driving member 251 to automatically set the section of the air flow in the ventilation channel according to the temperature signal so as to change the air volume and the air flow mode of the air flow.

For example, the rear-row control armrest is provided with a vehicle-mounted system which is in communication connection with the whole vehicle controller and is used for receiving and processing information of the temperature sensor 252 and the driving piece 251, and a rear-row passenger can perform adjustment operations such as air conditioning on the rear-row control armrest touch screen and the like, and can also perform air conditioning adjustment operations of the whole vehicle on a mobile phone. The air flow regulation mode of the air outlet can be combined with a vehicle machine system and is used for intelligent regulation of the air outlet of the vehicle seat, so that the problem of weak air quantity of a rear air conditioner can be greatly solved.

In some embodiments, referring to fig. 1 and 2, the ventilation air duct 221 and the trim opening 21 are both integrally formed with the seat back 2. Therefore, the whole vehicle seat has high integration level, simple structure and convenient mass production. In addition, it should be noted that, in the embodiment of the present utility model, the structure of the decorative opening 21 as the air outlet, the ventilation holes on the decorative opening 21 are all in the form of no blade, so that the assembly process of the assembly line of the vehicle seat can be reduced, the consistency control capability is improved, the ventilation size can be designed smaller, the design concept of the permeability of the modeling is maintained visually, and meanwhile, no obvious blade visual sense is provided.
