Preferably, the single-airbag inflation device, the single-airbag exhaust device and the inflatable airbag are communicated with the pipeline.

Preferably, said inflatable bladder is a one-way expandable bladder. When the inflatable air bag is inflated and extended, the inflatable air bag is limited to be extended towards the front of the cushion body, and a telescopic structure, such as an accordion bellows structure, can be adopted.

Preferably, the inflatable airbag is in the form of a strip, one side of the inflatable airbag is fixed to the cushion body, and the other side of the inflatable airbag is provided with a hard panel, and the hard panels are connected to each other. Inflatable airbag material is softer, and the easy deformation in pressurized back can not transmit pressure well, and this scheme adopts stereoplasm panel and user's health contact, and the stereoplasm panel can transmit pressure better.

Preferably, the inflatable airbag further comprises a soft cushion, a hard panel is arranged outside the inflatable airbag, the soft cushion covers the hard panel, and the soft cushion is connected with the hard panel arranged outside the inflatable airbag.

Therefore, the utility model discloses following beneficial effect has: it is rational in infrastructure, can realize quick aerate, lose heart, can accurate regulation to spinal position supporting pressure.
