Description

[Technical field]

[0001] The present application relates to the field of back cushions for automobile seats, and in particular to ventilated back cushions for automobile seats. [Background technology]

[0002] Automobiles are common and widely used vehicles in today's world. With the development of the times and the improvement of people's daily living standards, the demands for driving comfort in automobiles are increasing. Not only are there demands for automobiles with high maneuverability, but also for better comfort.

[0003] However, during the automobile manufacturing process, it is necessary to adjust the vehicle to suit the usage environment of each vehicle model. When the adjustment is made in favor of comfort, the vehicle's maneuverability is partially sacrificed. The same is true in reverse, especially in the adjustment of SUVs and off-road vehicles, where the sacrifice of comfort is relatively large.

[0004] Since the seat of a car is the main aspect that is the source of comfort for the passengers, there are many seat cushions and back cushions for car seats. As for the back cushion, it is often seen in daily life as a breathable back cushion. In hot summer, the driver is easy to sweat in the car, especially on the back, which greatly affects the comfort. This breathable back cushion can increase the breathability to a certain extent and improve the comfort of the driver. For example, the ventilated back cushion for car seats with the Chinese utility model registration number CN203211145U is provided with a back cushion cover, a plug with a speed control, a back cushion body and a back cushion front plate are installed in the back cushion cover, a fan mounting chamber is installed on both sides of the front lower end of the back cushion body, a turbo fan is installed in the fan mounting chamber, an outlet duct is installed around the fan mounting chamber, a back cushion front plate is installed at the front end of the back cushion body, and at the same time, an air outlet is installed at the position corresponding to the outlet duct in the back cushion front plate.

[0005] Regarding the above related technologies, the inventor believes that although the ventilable back cushion can play a role in ventilation, there is still a problem that the ventilation effect is poor when riding for a long time, and the main reason is that the back cushion is subjected to backward pressure while driving, and the back cushion may shift due to the swaying of the vehicle or the occupant adjusting his / her sitting position, or the driver may lean back for a long time, so that the position of the fan is too close to the seat or the back of the driver's body, reducing the amount of airflow or obstructing the airflow, making the fan more likely to break. Summary of the Invention [Problem to be solved by the invention]

[0006] In order to solve the problems in the above-mentioned related art where the fan is positioned too close to the seat or the back of the driver's body due to the driver leaning back for a long time, the amount of airflow is reduced, or the fan is easily damaged due to the obstruction of the airflow, the present application provides a ventilable back cushion for an automobile seat. [Means for solving the problem]

By installing the support protrusion, a large ventilation space is formed between the back of the back cushion and the chair, and the ventilation space can ensure sufficient ventilation even without installing a fan, and the convection effect of the air passing through the ventilation hole is stronger, especially when the passenger leans back and presses the back cushion. And by installing the fan installation part at a position close to the support protrusion, the position of the fan is not too close to the chair or the back of the passenger's body even when the passenger leans back, so the problems of reduced airflow and obstruction of airflow are greatly improved, and the ventilation effect is stronger, more noticeable and better. 2. The inclined structure and the arc-shaped transition surface at the upper, middle and lower parts of the main body can firmly support the passenger's waist and back during use, and can better improve the volume and airflow. 3. The support edge can improve the riding comfort of the passengers. Whether driving or resting in the car, it can provide a certain support effect to both sides of the passenger's waist. 4. By installing the guide groove, the air can be diffused to the edge after being blocked, effectively improving the ventilation effect, and does not affect the volume of airflow or the air volume. 5. The reinforcing ribs effectively increase the support strength, and prevent the back cushion from being significantly deformed when leaning back for a long time. This largely ensures the normal operation of the fan and prevents the fan from being damaged by pressure to a certain extent. 6. By installing a concave groove at the position corresponding to the support protrusion on the front of the bottom of the body, the air can be better diffused to the edge after being obstructed, and the ventilation effect is effectively improved. 7. By installing the elastic support, the problem of the back cushion displacement caused by adjusting the sitting position during leaning back for a long time can be avoided. The elastic support also helps to reduce the problem of the fan position being compressed by the force of leaning back, greatly improving the reliability of the use of the back cushion.
