Description

Technical Field

[0001] The utility model specifically relates to the technical field of automobile seats, in particular to a fan mounting base for seat ventilation. Background Art

[0002] Ventilated seats are designed with ventilation function on the seats.

[0003] Its main advantages include:

[0004] Improve comfort: It can effectively improve the stuffy feeling when riding, especially in hot weather or when driving for a long time, making the driver and passengers feel more refreshed.

[0005] Reduces sweat accumulation: Helps keep the contact surface between the body and the seat dry, avoiding the discomfort and stickiness caused by sweat.

[0006] Improve health: Good ventilation can reduce the chance of bacterial and fungal growth, which is beneficial to skin health.

[0007] There are usually two ways to implement ventilated seats:

[0008] Built-in fan type: A small fan is installed inside the seat, which draws air in and blows it out from the seat surface through the operation of the fan.

[0009] Perforated type: There are many tiny holes on the surface of the seat, through which air can circulate.
