Blast-Resistant Vehicle Seat

Stage: Prototype

The Blast-Resistant Vehicle Seat offers new applications of fluidized bed technologies and is ideal for use in military vehicles, such as the Mine Resistant Ambush Protected (MRAP). The seat consists of a rigid bed affixed to the vehicle with sand-filled polymer channels on top of the seat frame. When the seat is occupied, gas is directed into the channels to fluidize the sand, conforming perfectly to the shape of the occupant.

The Blast-Resistant Vehicle Seat couples the occupant to the vehicle, conforms to the passenger, is easily configurable to a wide variety of occupants and body types, and can help in environments where thermal management is a consideration. The seat can be custom fit for any vehicle.
