Background
The pneumatic system of the vehicle seat is generally composed of a gas source body, a gas circuit control valve, a pneumatic air bag body and a gas pipeline connected between the control valve group and the pneumatic bag body.
When the pneumatic system is inflated to actuate, the air flow output by the air source body inflates the massage pneumatic bag body through the air path control valve group. When the air flow passes through the tail end of the air pipe and is further input into the pneumatic air bag body, the high-speed air flow in the air pipeline is quickly sprayed into the empty massage air bag body, and local resonance noise is easily caused due to quick pressure reduction of the air at the outlet of the pipeline and air flow friction at the edge of the outlet.
At present, the air bag body and the pipeline connecting part are usually silenced by using surface attachments such as a felt cover and a silencing sheath, however, the surface attachments easily cause the unevenness and the foreign body sensation of the seat surface because the massage air bag body is usually laid on a sponge cushion in the seat surface cover facing to the human body side of a passenger.
