External vehicle window glass protection against sharp objects

Abstract

An external vehicle window glass protection system for protecting against static or moving sharp objects. It includes a relatively soft and lightweight layered armor panel, and a releasable mounting system to mount the armor panel on a vehicle door to cover the glass window. The layered armor panel has at least two layers of materials: an outer hard material layer to provide stab resistance and yield large plastic deformation/damage, and an inner soft material layer to reduce the contact force and absorb or dissipate kinetic energy of moving sharp object. The armor panel mounting system has an armor package with the armor panel inside, a back sheet behind the vehicle door folded around the large curved door edge to provide vertical constraint, and a side sheet folded around the vertical edge of the door to provide horizontal constraint. These two sheets are releasably connected using fasteners.
