Trimming cover for display device`s frame in motor vehicle, has light conductor constituted of double prism shaped transparent material block such that infrared ray is subjected to successive reflections to attain keys/buttons and detector

摘要

The cover (10) has a light conductor (12) with an upper end (16) exposed outside a contour of the cover and transmitting an infrared ray towards control keys or buttons provided on a frame (3) to control functions of a display device (2). The light conductor is constituted of a double prism shaped transparent material block (13) such that the ray delivered horizontally from a remote selector is subjected to successive vertical and horizontal reflections to attain the keys/buttons and a detector (6), where the block is formed of polycarbonate.
