DYNAMIC TESTING OF RESTRAINT SYSTEMS AND TIE-DOWNS FOR USE WITH VEHICLE OCCUPANTS SEATED IN POWERED WHEELCHAIRS

Thirty sled tests of wheelchair tie-downs and restraint systems were conducted using Everest and Jennings power wheelchairs and a 50th percentile male dummy. Twenty-nine tests were for a sled velocity differential of 20 mph at 16 G's deceleration. One test was for 30 mph at 20 G's. For each test top and side view high speed cameras recorded the impact event at approximately 1000 frames/second and seat belt load cells recorded the belt tension time histories. For the 30 mph test (80M029) triaxial head and chest accelerometers were used to compute head and chest resultant acceleration. This report describes these thirty tests and the impact results.
