CHILD RESTRAINT SYSTEM. FRONTAL IMPACT PERFORMANCE

THIS REPORT COVERS THE FIRST PART OF A SERIES OF INVESTIGATIONS OF CHILD RESTRAINT SYSTEMS PERFORMED BY THE NATIONAL SWEDISH ROAD AND TRAFFIC RESEARCH INSTITUTE. THE PROJECT WAS STARTED IN ORDER TO: 1. DEFINE THE STATE OF THE ART OF DESIGN CONCEPTS, MEDICAL KNOWLEDGE, REGULATIONS AND IMPACT PERFORMANCE OF DIFFERENT SYSTEMS. 2. RECOMMEND COMPLIANCE TEST PROCEDURES AND PERFORMANCE CRITERIA. THE FIRST PARTS OF THE REPORT DESCRIBE EARLIER RESEARCH IN THIS FIELD AND THE PRESENT HARDWARE SITUATION IN SWEDEN. MEDICAL ASPECTS AND CURRENT TEST METHODS ARE ALSO PRESENTED. 34 FRONTAL IMPACT TESTS WERE MADE WITH 25 SYSTEMS. IMPACT SPEED WAS 30 MPH AND THE DECELERATION LEVEL 15-20 G. ANTHROPOMETRIC DUMMIES WERE USED AND THE MEASUREMENTS INCLUDED DUMMY AND SLED ACCELERATIONS, FORCES AND DISPLACEMENTS. THE SYSTEM WERE SEPARATED INTO: 1. REARWARD FACING SYSTEMS AND BELTS WITH UPPER TORSO STRAPS. 4. LAP BELTS, SHIELDS CUSHIONS AND HARNESSES. 5. HOOKOVER SEATS. IT IS SHOWN THAT THE REARWARD FACING SYSTEMS OF TYPE 1 AND 2 HAVE A CONSIDERABLY BETTER PROTECTION PERFORMANCE THAN THE OTHER TYPES ESPECIALLY CONCERNING HEAD ACCELERATION AND DISPLACEMENT. GENERAL RECOMMENDATIONS FOR IMPROVEMENTS OF THE PROTECTION PERFORMANCE AND HANDLING OF REARWARD FACING SEATS ARE ALSO INCLUDED IN THE REPORT.
