Seat Ventilation in Cars

seat ventilation

Seat ventilation means that the designer injects air into the seat with a fan, and the air flows out from the small holes on the seat surface to realize the ventilation function.

When the passenger sits on the seat, the back of the body is in close contact with the seat surface, and the air in the contact part is not ventilated, which is not conducive to the elimination of sweat, which will make the human body feel uncomfortable. The ventilation function effectively improves the air circulation environment of the contact part between the human body and the seat surface. Even if you ride for a long time, the contact surface between the body and the seat will be dry and comfortable.

working principle

Seat ventilation is to add a fan on the seat cushion and the back of the foam back. The fan is used to inhale the air and then introduce it into the ventilation layer, and the air flow from the surface of the ventilation layer penetrates upward through the heating pad and flows to the surface of the seat cover (seat cover). It is made of perforated skin), so that the occupants can use the ventilation function to disperse the sweat on the back of the buttocks and bring comfort to the passengers in hot weather.

performance requirements

Noise of ventilation system: When the seat is empty, the working noise of the test ventilation device is less than 50 decibels.

Operating voltage range: The operating voltage of the ventilation unit is +9V to +16V. When the working voltage is lower than the working voltage, the low-voltage protection will automatically short-circuit and the ventilation device will stop working.

Entering and exiting simulation: The test swings a standard dummy's buttocks within a certain angle, and rotates the dummy's buttocks from the inner side of the seat cushion to the outer side. The rotation of the buttocks to the outermost side is a cycle, and a total of specified cycles are required. The ventilation function is required to be intact after the test.

Knee test: In the test, a ball head simulating the knee is loaded with a certain force on the seat cushion (there is a ventilation device area below), and one cycle is up and down movement, and a total of specified cycles are required. The ventilation function is required to be intact after the test.

Cushion and backrest driving simulation test: At room temperature, the dummy sits on the seat cushion/backrest in a simulated normal sitting posture. The experiments are carried out for a specified period, and the experimental results require that the ventilation function is intact.

Thermal imaging response to a ventilation device: at room temperature, heat the seat to be tested to 500C, turn on the ventilation switch, and test the temperature of the ventilation area of the seat at regular intervals, and require that the temperature change does not change significantly in the ventilation area.
