5、 AUG2014Ambulance Patient Compartment Seating Integrity and Occupant RestraintRATIONALEThis revision includes clarification for bench seat testing to ensure a single or multi seat bench is tested in the same manner as a single, standalone captains style seat. A reference to the Code of Federal Regul

6、ations, Title 49, Part 571.210 has been added to assist in determining when multiple anthropomorphic test devices should be used during a single test event. This revision also provides the ability for test facilities to utilize either the Hybrid III or ES2-re anthropomorphic test device for side imp

7、act testing relative to seated occupants orientation.1. SCOPEThis SAE Recommended Practice describes the testing procedures that may be used to evaluate the integrity of groundambulance-based occupant seating and occupant restraint systems for workers and civilians transported in the patient compart

8、ment of an ambulance when exposed to a frontal or side impact. This Recommended Practice was based on ambulance patient compartment dynamics and is not applicable to other vehicle applications or seating positions. This Recommended Practice is structured to accommodate seating systems installed in m

9、ultiple attitudes including but not limited to side-facing, rear-facing, and forward-facing. Its purpose is to provide ambulance seating manufacturers, ambulanceoccupant restraint manufacturers, ambulance builders, and end-users with testing procedures and, where appropriate, acceptance criteria tha

10、t, to a great extent ensures the occupant seating and occupant restraint system meet similar performance criteria as FMVSS 208 requires for seat belted passengers in light vehicles. The test conditions utilized are standardized orientations that do not reflect potential conditions that may exist pri

11、or to impact such as braking and/or steering and their effects on the initial positions of the occupants and surfaces relative to the occupants. Descriptions of the test set-up, test instrumentation, photographic/video coverage, text fixture, and performance metrics are included.SAE INTERNATIONAL J3
