Abstract: A fluid safety liner includes a liner of closed-cell foam that uses a series of channels and reservoirs to spread forces and distribute fluid contained within the liner throughout different areas of the liner. The liner is useable in protective gear such as a helmet and has a shape that conforms to the area of protection. The channel and reservoir system generally includes a mesh of coupled channels and reservoirs in the closed-cell foam. The channel and reservoir system also generally includes an incompressible fluid movable throughout the system for redistributing pressure and absorbing the force of any impact through viscous flow. The reduction in peak force and lengthening of the duration of the force reduces the biomechanical severity (e.g. HIC, Head Injury Criterion) of a blow to the protective gear.
