WINDSCREENS FOR PRIVATE MOTOR CARS

WINDSCHUTZSCHEIBEN VON PERSONENKRAFTWAGEN

BOTH TYPES OF WINDSCREEN GLASS IN COMMON USE TODAY, TOUGHENED SAFETY GLASS AND LAMINATED SAFETY GLASS, ARE COMPARED. REGARDING THE TECHNICAL QUALITIES IT IS ESTABLISHED THAT BOTH FORMS OF GLASS HAVE VIRTUALLY THE SAME OPTICAL CHARACTERISTICS; THE ULTIMATE STRESS LIMITS OF TOUGHENED GLASS LIE RATHER HIGHER THAN THOSE OF THE LAMINATED. CONSIDERING THE ACCIDENT-RELATED QUALITIES IT IS FOUND THAT IN ACCIDENTS AFFECTING TOUGHENED GLASS THE DANGER OF EYE INJURIES IS PARTICULARLY HIGH AND NON-BELTED OCCUPANTS CAN BE THROWN OUT OF THE CAR, A DANGER WHICH IS ALMOST NON EXISTENT WHERE LAMINATED GLASS HAS BEEN USED. ANOTHER ADVANTAGE OF LAMINATED GLASS IS THAT ONLY A MINIMAL HINDRANCE TO VISIBILITY IS CAUSED WHEN THE SCREEN IS BROKEN. ALTOGETHER THERE ARE CONSIDERABLE ADVANTAGES IN THE USE OF LAMINATED GLASS COMPARED TO TOUGHENED. A PROHIBITION OF THE USE OF TOUGHENED GLASS, AS HAS BEEN SUGGESTED IN MANY COUNTRIES, HAS AGAINST IT THE FACT THAT CORRECT USE OF SAFETY BELTS HAS REDUCED THE FREQUENCY OF WINDSCREEN INJURIES AND REDUCED THEIR SEVERITY. THERE ARE ALSO ECONOMIC REASONS AGAINST THE SUBSTITUTION OF THE TOUGHENED GLASS BY THE MORE EXPENSIVE LAMINATED VARIETY.
