An above ground shelter that provides protection against dangerous events including micro-bursts, tornadoes, hurricanes, earthquakes, and personal attack. The shelter is a low profile standalone structure that consists of top, bottom, and side walls and an access door. The shelter is specifically designed for installation in the crawl space below mobile homes, to be entered through an access hatch interior to the mobile home. The shelter is also designed to serve as an entry platform to mobile homes, and as such is configurable with steps, railings, canopies, and handicap access ramps. The shelter's exterior geometric shape was specifically developed to provide optimal deflection of air-born debris, and to provide aerodynamic down force in high velocity winds. In addition, the shelter geometry allows transport and installation by existing commercial equipment. The shelter is of sufficient weight that, in combination with down force aero loads, does not require mandatory attachment to the ground.

1. An above ground safety shelter defining an enclosed area for receiving and protecting at least one person from dangerous events including tornadoes, hurricanes, high winds and airborne debris, said shelter comprising:at least one upwardly inclined wall having an upper distal end and a lower distal end, said inclined wall having an outer surface and including reinforcement means including concrete, a plurality of steel bars, an outer skin, and an inner skin for absorbing and dissipating impacting energy as a means of increasing penetration resistance; a roof disposed at said upper distal end of said at least one inclined wall; a floor disposed at said lower distal end of said at least one inclined wall; and at least one door for accessing the interior of said enclosed area; said at least one inclined wall being monolithic and being geometrically shaped for deflecting wind blown debris to reduce energy absorption by said at least one inclined wall from any impacts of windblown debris; said at least one inclined wall being further aerodynamically shaped to develop down forces responsive to impact by the high velocity winds, said down forces disposed for increasing the structural stability of the shelter by enhancing the forces necessary to keep the shelter on the ground.
