SAFETY HARNESS-PROTECTIVE LEVEL FOR VARIOUS COMBINATIONS OF BELTS AND SEATS

RALLEYBALTEN SKYDDSNIVA VID OLIKA KOMBINATIONER AV BALTEN OCH STOLAR

As a basis for a prospective modification of the present seat-belt regulation, the protective level of safety harnesses compared with three-point belts has been studied. Biomechanical tests were carried out with different combinations of belts and seats. The results showed that a three-point belt on a conventional seat offered the best protection at frontal impacts. The geometry of the safety harness (inverted Y-harness and four-point belt) induces the lap belt to slide over the iliac crest and the restraint effect will be on the abdomen (submarining). The shoulder straps expose the wearer's shoulders and back to high stresses (inverted Y-harness, four-point belt and six-point belt) at frontal impacts. Some solutions, which may result in an increase of the protective level on the system safety harness and racing-car seat are discussed in the report.
