UHAH-1 Helicopter - The MitiGator™ Cushion System

Under Phase I-III Small Business Innovation Research (SBIR) programs with NAVAIRSYSCOM, SEAS has developed a seat cushion system (utilizing one or more layers of The MitiGator™ Technology) that dissipates much of the energy of impacts and prevents that energy from passing through to the human body, thus reducing the level of injury sustained.  The system is as effective against repeated impacts (high speed boats or ground vehicles) as it is against one-time events  (crash landings). 

The MitiGator™ utilized in the cushion has been shown to attenuate as much as 40% more energy than standard or conformal foam systems. The MitiGator™ Technology is an engineered system; specific MitiGator™  configurations can be designed for specific applications.

Along with its good energy-attenuating characteristics, The MitiGator™  has the added advantage of returning to its original configuration after impact, making it suitable for repeated impacts. The cushion is made of materials that will survive in a marine environment. Studies have also shown that the system also acts as a vibration attenuating system as well. This reduces fatigue and pain, allowing crewmembers to concentrate on the mission or task at hand.  

Our seat cushions also feature E-A-R Conformal Foam (originally developed for NASA) seating surfaces to provide unsurpassed comfort and relief from pressure point pain.  These foams contribute additional impact protection, vibration isolation and durability.
