Abstract
Test results indicate that the forces that lap and shoulder belted adults can exert in holding an infant dummy in their laps are far less than the inertial force that would be exerted by a 7-9 kg infant decelerated at more than 30 G's. Thus in a motor vehicle frontal barrier crash at 50 km/hr, an infant even when held hightly by a restrained adult would almost certainly strike the dash or windshield.
