Abstract (en)
[origin: WO2017084894A1] The invention relates to a cover element (506) for covering a projection opening (508) of a head-up display (500) for a vehicle (502), wherein the projection opening (508) is arranged in a beam path between an image generating unit (504) of the head-up display (500) and a deflecting element (510) of the vehicle (502). The cover element (506) comprises a polarisation changing element (516), which is designed in order to change a polarisation of a light beam (512) guided in the beam path between a first polarisation type and a second polarisation type, and a polarisation filter (514) which is transparent for a light beam (512) polarised in a predetermined polarisation direction in the second polarisation type, wherein said polarisation filter is or can be arranged between the polarisation changing element (516) and the windscreen (510).
