Abstract:
1. An energy absorbing device adapted for carrying a passenger seat; said device comprising (a) a base fixedly attached to a pre-existing vehicle seat, wherein the base rests atop a seat bottom of the pre-existing vehicle seat; (b) a member displaceable relative to said base; and (c) at least one energy-absorbing arrangement interconnecting said base and said displaceable member; said energy-absorbing arrangement comprises a plastically deformable absorbing element in response to stresses greater than a predetermined threshold stress; wherein said energy-absorbing arrangement comprises a hingely interconnected four-bar sub-arrangement configured to be reshaped angularly when said device is stressed; said four-bar sub-arrangement comprises first and second bars substantially parallel to said base; said first bar is mechanically secured to said base; said second bar is mechanically secured to said displaceable member; third and fourth bars each being one piece, the third and fourth bars hingely interconnect terminals of said first and second bars; and wherein angular reshaping is controlled by said deformable element secured to said base and connected to said four-bar sub-arrangement.
