A kinetic child restraint device which is fastened to or integrated into the seat of a vehicle to provide for 360 degree spherical impact protection to significantly reduce the risk of injury to a child in the event of a collision. Seating loads are borne on the support surface from the weight of an occupant by elastic deformation of the bladder. The primary parameters to be measured include fluidparticle concentration, fluidparticle mixture volumetric flow, and particle size.
