Technology Marketing Summary

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.


Conforms to the person's body with no pressure points and is ergonomically sound.

Allows the occupant to control heating and cooling, especially advantageous in harsh environments.

Controls stiffness of seat by absorbing some of the force/impact during an accident.


Protects the warfighter from impact trauma from improvised explosive devices.

Fits all body sizes and forms a comfortable, solid seat bed.

Protects the body, shoulders, neck and back in a blast.

Can be reconfigured any time the occupant needs to change position.

Applications and Industries

Homeland security; military; law enforcement; general automotive; racing; aircraft.

Blast resistant vehicle seat
Disclosed are various seats for vehicles particularly military vehicles that are susceptible to attack by road-bed explosive devices such as land mines or improvised explosive devices. The seats often have rigid seat shells and may include rigid bracing for rigidly securing the seat to the chassis of the vehicle. Typically embodiments include channels and particulate media such as sand disposed in the channels. A gas distribution system is generally employed to pump a gas through the channels and in some embodiments the gas is provided at a pressure sufficient to fluidize the particulate media when an occupant is sitting on the seat.
