THERMOPLASTIC FILM FOR A LAMINATED GLASS PANE HAVING A NONLINEAR CONTINUOUS WEDGE INSERT IN THE VERTICAL AND HORIZONTAL DIRECTION IN SOME SECTIONS

摘要

The invention relates to a thermoplastic film (F) for a laminated-glass pane (1) having a non-linear continuous wedge insert in the vertical and horizontal direction in some sections. In the vertical direction, the laminated-glass pane (1) is further from an observer at a lower end than at an upper end from the perspective of the observer. In a laminated-glass pane (1) equipped with the thermoplastic film, the thermoplastic film (F) is located between two glass layers (GS1, GS2). The thermoplastic film (F) has at least a first section (A2) having a wedge angle profile that is continuous and non-linear in the vertical and horizontal direction, such that ghost images from a head-up display are minimized in the region of the first section (A2). The thermoplastic film (F) also minimizes double images in transmission in the first section (A2) and in further sections.
