    Abstract: A deployable ramp is provided for a cargo loading system of a vehicle. The ramp includes one or more rigid element having a surface for supporting a load. The ramp further includes one or more bladders defining a chamber that is fluidly connected to an outlet of a compressor. The chamber is adapted to receive a fluid from the compressor. The bladder is attached to rigid element, and the at bladder is movable to a collapsed state where the chamber has a first volume. The bladder is further movable to an expanded state where the chamber has a second volume and contains a pressurized fluid for supporting the rigid element, in response to the bladder receiving the fluid from the compressor. The second volume is higher than the first volume.
