Ambulance Crash Test Footage

View crash test footage, conducted by the Automotive Safety Program at the University of Michigan Transportation Research Institute, of an isolette and child restraint systems on an ambulance cot. Descriptions of the tests follow the crash test footage.

Crash Test 1

  • Test date: January 30, 1990.
  • 3 year old test dummy.
  • Convertible seat facing the rear of the ambulance on Ferno 30 ambulance cot with Ferno 175 ambulance cot fastening system.
  • The convertible seat was reclined with the harness through the middle slots. The convertible CSS was installed using a cot belt through each (rear facing and forward facing) belt path.
  • Frontal impact at 48km/h (30 mph), 20 G with cot backrest fully reclined and side rails up.
  • This test dummy was not instrumented. Failure of the fastener system appeared to be imminent at the conclusion of the test. If safety lanyards had not been used, it is suspected that the fastener system would have failed.

Crash Test 2

  • Test date: January 30, 1990.
  • Low birth weight (LBW) test dummy in Air-Shields TI100 transport incubator on Ferno-Washington incubator stand with a 4 point clamp.
  • Ferno Washington 175 ambulance cot fastener, Hayes Marsupette air-bubble restraint.
  • Frontal impact at 48km/h (30 mph), 21 G. Incubator was oriented longitudinal with dummy head rearward and slack ropes attached to stand and incubator.
  • Incubator and stand rotated in direction of impact with frame twisting severely. The fastener system released causing the incubator to hit the front of the sled, which in turn caused the plexi-glass hood to shatter, and the air-bubble restraint and dummy to be ejected. This test dummy was not instrumented.

Crash Test 3

  • Test date: July 11, 2000.
  • CRABI 6 month old test dummy in car bed with
  • The car bed was installed on a Ferno Mobile Transporter 35-AST with sheet metal back using anchor loops on each side of the car bed.
  • The Ferno Mobile Transporter 35-AST was attached to a simulated ambulance floor on the sled using a Ferno Stat Trac 185 cot fastening system.
  • Frontal impact at 48 km/h (30 mph), 23 G. Cot back rest was fully upright, side rails down. The car bed was positioned side facing on the ambulance cot with the cot belts through the car bed’s belt loops (the extra set was added).
  • The chest G resultant was 55G. The head injury criterian was 505. The dummy’s head and torso were fully contained.

Crash Test 4

  • Test date: July 11, 2000.
  • 3 year old, 15 kg test dummy weighted to 18kg.
  • Convertible seat facing the rear of the ambulance on Ferno Mobile Transporter 35-AST with sheet metal back on Ferno Stat Trac 185 cot fastening system;
  • Convertible seat reclined, harness through middle slots; cot belts through both rear facing and forward facing belt paths.
  • Frontal impact at 48km/h (30 mph), 23 G, simulated ambulance floor on impact sled; cot backrest fully up with side rails down.
  • Good restraint performance during impact and rebound. Chest G resultant was 43G. Head Injury Criterian was 501. Head target was well contained.
