Abstract

One hundred and three frontal collision tests with fresh human cadavers were carried out on the deceleration sled, at an impact velocity of 50 km/h in 74 tests, 40 km/h in 22 tests, and 30 km/h in 7 tests. Three-point standard belts with retractor were used in 56 tests, and special belt system with broadening of surface pressure in 17 tests. The test objective was to determine the tolerance level of the thorax, the cervical vertebra and the upper thoracic vertebra under the above conditions, with a constant deceleration of about 20 g (equivalent stopping distance at 50 km/h amounts 42 cm, at 40 km/h amounts 31 cm, and at 30 km/h it is 20 cm). Thereby the age group of 12-30 years reached the thorax tolerance level at an impact velocity of still below 50 km/h, the age-group of 30 to 50 years of age of below 40 km/h and the ones over 50 years of age of below 30 km/h. The influence of age in view of the severity of the injuries sustained in the tests is of decisive importance. The degree of injuries being dependent upon sex and weight could not be proved. The inclination of the head with a rotation of body, neck and head around the axis of the diagonal shoulder belt is the cause of the injuries to the cervical and thoracic vertebra.
