Abstract
At least some aspects of the present disclose feature a flow control device to be used between two inflatable sections. The flow control device is a one-way flow control device allowing inflating medium to flow in one direction. In such embodiments, the flow control device is in an open state when a first inflatable section is inflated such that a second inflatable section is also inflated. The flow control device is in close state when the second inflatable section is inflated such that the first inflatable section is not inflated.
