Response of Belted Dummy and Cadaver to Rear Impact

摘要

Sled impact tests were conducted to simulate the motion of a standard size car at rest impacted from the rear by a second car of equal weight travelling at 32 mph. The test subjects were anthropomorphic dummies and unembalmed cadavers. They were seated in a bench seat and were unbelted. In one test mode the seatback was held rigid and in a second test mode the seatback rotated rearward in response to the test subject's impact loading. The major difference for either subject, between the rigid and the deflecting seatback mode was that the deflecting seatback reduced load force magnitude but increased time duration. Autopsies indicated that two of the three cadavers suffered neck injuries reaching AIS 3 scale while the third had no injury.
