Crash test according to ISO 7176-19 & 10542 - electric wheelchair with a docking system

A sharp bracket causes the lap belt to get torn on the right side of the wheelchair, while holding in the other. This causes the shoulder belt to cut with an enormous force from just under the ribs towards the head, resulting in tearing off the head of the occupant (decapitated).  

Safety belt’s webbing should not be worn or twisted and must be protected against sharp edges and corners. Occupant is decapitated, due to the occupant restraint being torn by a sharp edge on the right side of the wheelchair.
