Abstract
An improved rigid safety-vest structure intended for general use in hazardous-construction environments, such as encountered by trench and tunnel workers. Sudden cave-in situations are said by the U.S. Federal-agency O.S.H.A. to tragically take many lives annually to insidious suffocation, attributable to simple impairment of a workers'upper-abdomen/thorax region by suddenly surrounding cave-in earth. The notion of the HardJacket.TM. being to prevent these fatalities, by providing the worker a light-weight aerated upper-torso safety-vest within which an earthen immobilized worker can maintain their vital breathing action, -while efforts are being made to bodily extricate them. The disclosure includes a three-paneled frontally opening self-donning structure fabricated with an interlaced metal truss-structure, preferably enveloped in a bright-colored aerating nylon-fabric; plus a generic-variant embodiment, formed of inner and outer rigid-skins separated by a rigid foam-core interior. All iterations employ a comfortably flexile shoulder suspension arrangement, and may be provided with optional backside rollers, enabling a worker to more easily scoot beneath an overhanging ledge or vehicle.
