Ventilated type vehicle chair back

Abstract

The invention discloses a ventilated type vehicle chair back which comprises a body, at least one air channel, more than two air vents and an air deflector, wherein the body is provided with a leaning surface, two side surfaces and a first combining part; one of the two side surfaces is provided with at least one air inlet; the first combining part is located on one side of the air inlet; the air channel is arranged on the body and communicated with the air inlet; the air vents are arranged on the leaning surface and communicated with the air channel; the air deflector is provided with a second combining part; and the second combining part is connected with the first combining part. The ventilated vehicle chair back disclosed by the invention has relatively good air permeability so as to avoid muggy feeling on the back of the passenger.

Description

technical field [0001] The invention relates to a vehicle seat back, in particular to a vehicle seat back with ventilation function. Background technique [0002] In order to improve the comfort of the general vehicle seat back, a seat back filled with a foam layer has been developed on the market, and the seat back cover is provided with a leather leaning surface. Although this kind of seat back allows the driver to lean comfortably, But there is the problem that it is not easy to dissipate heat, so that the driver has a hot and stuffy feeling in the back. [0003] In order to solve this problem, there are Chinese Taiwan Patent Nos. TWM261396 and TWM373838 patents in the prior art.

AI Technical Summary

Problems solved by technology

[0002] In order to improve the comfort of the general vehicle seat back, a seat back filled with a foam layer has been developed on the market, and the seat back cover is provided with a leather leaning surface. Although this kind of seat back allows the driver to lean comfortably, However, there is a problem that it is not easy to dissipate heat, which makes the driver feel uncomfortable with stuffy back

[0003] In order to solve this problem, there are Chinese Taiwan Patent Nos. TWM261396 and TWM373838 patents in the prior art, although the above-mentioned two patents can effectively overcome the stuffy technical problem that the back of the vehicle seat and the back of the human body are touched, but the above-mentioned two The technical means overcome by the patent all need to rely on additional electric power to drive the fan to generate airflow, or to install an additional air duct in the car body to guide the airflow from the fan or cold and hot air to the air passage reserved on the back of the vehicle seat. Patented technical means obviously have the following disadvantages:

[0004] First: Multiple structures such as fans and motors are needed to generate airflow, which makes the structure design of the vehicle seat back more complicated

[0005] Second: The design of generating cold and hot air on the back of the seat in the first point above is an additional product, and the installation is also more complicated. Consumers often need to pay an additional installation fee, even if the product is listed when the vehicle is produced. As a basic spare part, it will inevitably make the cost passed on to the sales price of the vehicle, which is not competitive

Even because of the high price of the product, this product is only used in high-end imported cars, so there is a shortcoming that this product cannot be popularized

[0006] Third: The practice of externally connecting components such as air ducts and fans causes the original narrow interior space to be compressed again, and even the exposed air ducts and other components will also affect the overall appearance of the interior and control response , so it is not an ideal design

[0007] Fourth: The most important point is that most of the above two patented products need to rely on additional power (such as batteries or plugged into the car body cigarette lighter) to drive the fan. As far as the battery is concerned, it will cost the battery and waste when the power is exhausted. Battery recycling, environmental protection issues, when the car body battery is used as the power source, there are disadvantages such as easily affecting the voltage stability of the engine and driving computer
