Patent attributes
An air bag module of inflatable mattress is disclosed. The inflatable mattress is provided with a lining for the air bag module to be placed therein, and a resilience supplying module being placed in the lining and resting on the air bag module. The air bag module includes at least one air bag unit. The air bag unit is provided with an air distribution layer and a hardness adjustment layer connected with the air distribution layer while located between the air distribution layer and the resilience supplying module. In the air distribution layer, air is inputted into each distributing air bag equally via intercommunication of distributing air bags, such that air from the distributing air bags is consistently received by each supporting air bag of the hardness adjustment layer. Thus, the problem of uneven surface of bed due to non-uniform inflation in the conventional structure is solved.
