According to the present invention there is provided an armor array for protecting a body to be protected from an incoming projectile having an anticipated impact direction. The armor array is constituted by at least a first and a second armor cassette, each comprising a top base plate and a bottom base plate sandwiching therebetween an expandable layer. The first and second armor cassettes are spaced apart by an intermediate depressible panel having a top and a bottom face, such that the bottom base plate of the first armor cassette faces the top face of the intermediate depressible panel and the top base plate of the second cassette faces the bottom face of the intermediate depressible panel. The armor array is constructed such that upon expansion of the expandable layer, caused by the impact of the incoming projectile, at least one of the bottom base plate of the first armor cassette and the top base plate of the second armor cassette is urged towards the intermediate depressible panel and depresses it.

Armor module and an armor array used therein

An energy absorbing device is provided for reducing acceleration resulting from a force of a high energy impact acting on one side of the device in an impact direction. The device includes two plates transverse to the impact direction, an energy absorbing mechanism between the plates, and a stabilizing mechanism having at least one pair of a projecting element and a receiving element, the projecting element comprised on one plate and a corresponding receiving element comprised on the other plate. Each pair is adapted for enabling the projecting element thereof to be at least partially received by the corresponding the receiving element in a manner to restrict relative displacement between the two plates at least in one direction different from the impact direction and to allow substantially free relative displacement between the plates in the impact direction.

Energy absorbing device for a vehicle seat

An energy absorbing device for reducing acceleration transmitted to a seated occupant in a vehicle as a result of a high energy impact. The device comprises a first energy absorbing mechanism having a first dimension in the impact direction and capable of undergoing predetermined elastic deformation in that direction; and a second energy absorbing mechanism having a second dimension in the impact direction, which is smaller than the first dimension by a distance corresponding to that elastic deformation. The second mechanism is loaded with the impact force after the first mechanism has undergone elastic deformation; the second mechanism comprises a material capable of progressive deformation. The device may comprise a restriction mechanism connecting the two plates, adapted to restrict displacement of the first plate relative to the second plate in any direction different from the impact direction.
