Performance of a Non-Lacerative Windshield in Case of Accident and Under Environmental Conditions 770246

The four-layer laminated Securiflex windshield
has been tested in simulated collisions at the Wayne State University up to 40 mph Barrier Equivalent Velocities, to demonstrate that it causes no laceration.
has been exposed to usual and extreme environmental conditions to demonstrate its serviceability in field use.
The new windshield consists of a conventional laminated construction (glass/high penetration resistant interlayer/glass) combined with a 0.5 mm innerlayer of plastic. Glass is used on the outer surface of the windshield to withstand the abrasion and scratching of sand, windshield wipers and cleaning. The laminated construction prevents penetration and provides a pocket or cushion action to decelerate the head without injury. The innerlayer is made of a special plastic film which protects the face of the occupants against laceration and eye injury during head impact. It also prevents glass particles and splinters from flying inside the vehicle from external impacts of stones and other objects.
The inner plastic film is abrasion and scratch resistant. Extended installation in vehicles has shown that it is not damaged through normal use.
The Securiflex construction has been exposed to high and low temperature and humidity, chemicals, food, cosmetics, cigarette, smoke, etc.: it is not adversely affected by these agents and has performed perfectly well in long term service tests.
