Abstract: A carrying case for a portable computer or other instrument requiring protection from injury during transport includes a body defining an interior recess, a lid for closing the recess, a bladder assembly in the recess including cushioning bladders and a cushioning and displacement bladder at the bottom of the recess and a sheath overlying the bladder. Insertion of an instrument into the recess collapses the cushioning and displacement bladder to pressurize all of the bladders in the assembly to engage and protect the computer from injury due to inertial shocks. The lid includes an insertion member which engages the computer when the lid is closed to move the computer to the final inserted position and increase the pressure in the bladder assembly.
