Five intersection-type collision experiments were conducted at 40 mph to provide data on several categories of collision performance. This paper presents the interactions of passenger heads with car windshields and side-glass. Instrumentation included 60 channels of force and acceleration data, supported by the photographic coverage of 40 cameras. Tri-axial accelerometers, mounted in anthropometric dummy heads and chests, and strain gauges bonded to windshields facilitated data collection on the relative collision performances of different types of safety glass.
