[0020] See also Figure 1-3 In this embodiment, a pneumatically adjustable headrest includes a headrest 1, a breathable pad 3 and an air pump 2. A fixing sleeve 16 is fixedly installed on the surface of the headrest 1. An anti-slip strip 17 is fixedly installed on the opposite side surface of the fixing sleeve 16. The headrest 1 can be fixed on the backrest of the car seat by the fixing sleeve 16. The anti-slip strip 17 can prevent the fixing sleeve 16 from being separated from the backrest of the car seat. The breathable pad 3 is a mesh cloth. The thickness of the breathable pad 3 is not less than five millimeters and not more than one centimeter. The headrest 1 and the breathable pad 3 A breathable pad disassembly mechanism is provided between the headrest 1 and the air pump 2, and an adjustment mechanism is provided between the headrest 1 and the air pump 2. The breathable pad disassembly mechanism includes a T-shaped pin 4 fixedly installed on the surface of the breathable pad 3, and a slot 5 is provided on the surface of the headrest 1. There are multiple T-shaped pins 4 and slots 5, and the multiple T-shaped pins 4 and slots 5 are evenly distributed on the surfaces of the breathable pad 3 and the headrest 1 respectively. The connection stability between the breathable pad 3 and the headrest 1 can be improved by using the multiple T-shaped pins 4 and slots 5, and a snap ring 6 is fixedly installed on the inner side of the slot 5.
