Crash test according to ISO 10542-2 with a 4 point strap tie-down system

 

This video shows an example of crash testing according to ISO 10542 part 2 utilizing a surrogate wheelchair with a mass of 85 kg. According to the standard, the surrogate wheelchair is representative of all wheelchairs and is solely being used to test the strength of tie-down straps and the occupant restraint.  

 

During this test the front tie-down straps adjusters failed. Notice the high forces involved, even under the rebound faze of the collision. A more solid adjuster had to be developed to solve this problem.

Had this product been marketed and involved in an accident without prior testing, it could have had serious consequences for the wheelchair user and other occupants in the vehicle.
