Energy Attenuation Bench Seat System

Description:

TECHNOLOGY AREA(S): Ground Sea 

OBJECTIVE: The Energy Attenuation Bench Seat System will protect and accommodate multiple sized Soldiers from a variety of typically injurious scenarios like Vehicle Borne Improvised Explosive Devices (VBIED), underbody blast, top/bottom attacks, crash, and rollover events. By consolidating seating to benches and reducing the overall footprint of the seat, vehicle length could be reduced achieving a significant overall weight savings. 

DESCRIPTION: Ground vehicle energy attenuating seat systems are traditionally designed to accommodate and protect a single Soldier with a prescribed distance between seats. Limited existing Military bench seating does not provide energy attenuation, desired accommodation, or an adequate level of Soldier endurance and performance. A new bench seating system shall be internally mounted in the vehicle with integrated restraint systems, and either provide or account for integrated or under-seat storage. The seat shall accommodate 4 fully encumbered occupants of varying size within the central 90th percentile and protect them during events including, but not limited to: underbody blast, crash, rollover, Top/Bottom attack, and VBIED. The bench seat shall be able to protect varying combinations of occupant sizes ranging from a single 5th percentile female up to four 95th percentile males, and allow for a minimum of 26" from centerline to centerline of each occupant. 

PHASE I: Define and determine the technical feasibility of developing an energy attenuation bench seat system that is lightweight, durable, and can protect the occupants from high energy inputs. The seat must protect and accommodate the central 90th percentile Soldier population while fully encumbered and be lightweight and durable enough to handle the rugged conditions encountered by ground vehicles. Seats must be FMVSS 207/210 compliant. The seat must, at a minimum, meet FMVSS 208 Injury Criteria (additional Injury Criteria will be provided once on contract) for the following tests: drop tower testing (up to 350g half sine pulse, delta V 10 m/s), and FMVSS 213 Child Seat Corridor Sled Testing. 

PHASE II: Develop and test at least 5 prototype seat systems that can protect and accommodate the Soldiers during high energy events including, but not limited to: blast, crash, rollover, and VBIED. Based on the findings in Phase I, refine the concept, develop a detailed design, and fabricate a simple prototype system for proof of concept. Identify steps necessary for fully developing a commercially viable seat system. Seats must be FMVSS 207/210 compliant. The seat must, at a minimum, meet FMVSS 208 Injury Criteria (additional Injury Criteria will be provided once on contract) for the following tests: drop tower testing (up to 350g half sine pulse, delta V 10 m/s), and FMVSS 213 Child Seat Corridor Sled Testing. 

PHASE III: Commercialization to Stryker (PM-SBCT), with potential integration in Next Generation Combat Vehicles (NGCV). Potential additional military applications include, but are not limited to other Combat Vehicles.
