Roof and Windshield Header Constructions

This paper briefly discusses the history and the problems of dynamic testing procedures relative to roof structure. A new Static Laboratory testing technique and its advantages are discussed.

The second part of this presentation outlines the subject of the windshield header design, the development of testing procedures, and the evolution of a windshield header design which provides a skidding action.

Tests conducted on the new design windshield header indicate that there is a definite reduction in potential head injury as a result of impact as compared to the conventional header construction. The new header surface minimizes the rearward head rotation and the abrupt change in head movement which occurs when contact is made with the rear wall of the header surface.
