Ventilation seat and back cushion for vehicle

Abstract

This invention, a venting sit-and-lean cushion for cars, is revealed with the feature of comprising of a main venting channel located at the jointing position of the said cushion and leaning cushion, an axle fan at the channel's end other than a cushion and an integrated leaning cushion; several sub venting channels are arranged inside the cushion and the leaning cushion while in connection with the main venting channel. Thanks to its good effect of the venting cushion for venting and heat emission, reasonable structure for quick location, this device eliminates the headaches like the discomfort of human body and the affects for AC normal functioning of cars and the relevant venting problems.

Description

technical field [0001] The invention relates to an automobile interior seat article, in particular to an automobile ventilated seat cushion. Background technique [0002] Motor vehicle compartments are basically equipped with air-conditioning equipment, and the ambient temperature in the compartment is generally comfortable, but after sitting in the car for a long time, the heat generated by the buttocks and back cannot be dissipated, especially the waist muscles are particularly prone to Fatigue will make people feel uncomfortable. In response to this situation, people have developed ventilated cushions or cushions to dissipate heat. However, the existing ventilated cushions or cushions achieve the purpose of heat dissipation through the air outlet of the automobile air conditioner or the ventilation of the fan. The structure is general. All are more complicated, and the effect of dispelling heat and eliminating fatigue is relatively poor. [0003] There is a kind of air c...

Problems solved by technology

[0002] Motor vehicle compartments are basically equipped with air-conditioning equipment, and the ambient temperature in the compartment is generally comfortable, but after sitting in the car for a long time, the heat generated by the buttocks and back cannot be dissipated, especially the waist muscles are particularly prone to Fatigue will make people feel uncomfortable. In response to this situation, people have developed ventilated cushions or cushions to dissipate heat. However, the existing ventilated cushions or cushions achieve the purpose of heat dissipation through the air outlet of the automobile air conditioner or the ventilation of the fan. The structure is general. They are more complicated, and the effect of heat dissipation and fatigue elimination is relatively poor

[0003] There is a kind of air cushion with ventilation pipes in the seat and back cushions on the market. The overall structure of the air cushion adopts air supply from the base, which can ventilate and dissipate heat to a certain extent, but the body weight may cause pipe blockage and wind speed loss at turns. , the ventilation effect is not ideal

Another U.S. patent (announcement date is August 19, 2004, and the announcement number is US2004 / 0160092A1, named "AVentiated Seating System") also discloses a ventilated seating system, which is provided with a cushion portion and a cushion portion ( These two parts are connected with a rotating shaft), the rotating shaft can rotate along the axis and is equipped with ventilation holes. Its working principle is that the air outlet of the car air conditioner is supplied with air through the rotating shaft to dissipate heat. This structure is more advanced than other similar products. , but it is also complex in structure, especially the rotation of the connecting shaft, resulting in difficult production, inconvenient installation, and increased fuel consumption of the vehicle
