Abstract

A combiner for a head-up display apparatus is integrally molded with a support for the combiner into a single piece. A baffle preventing direct occupant viewing of the display source of the head-up display may also be integrally molded for the combiner and the support. The integrally molded combiner and support provides for improved quality of the head-up display at a reduced price.

Claims

1. An apparatus comprising a single molded piece for a head-up display apparatus, the single molded piece including:

an optical combiner for the head-up display apparatus;

a support for the optical combiner; and

a baffle for preventing direct viewing of an image source by an occupant eye, wherein the single molded piece may be mounted via the support.

2. A head-up display apparatus wherein a combiner is integrally molded with a support for the combiner into a single piece and wherein a baffle is integrally molded with the combiner and the support into the single piece.

3. An apparatus comprising a single molded polycarbonate acrylic piece for a head-up display apparatus, the single molded piece including:

an optical combiner for the head-up display apparatus including a first surface closest to an occupant eye and second surface furthest from the occupant eye, and wherein the first surface is coated with a reflective coating and the second surface is coated with an anti-reflective coating;

a support for the optical combiner, wherein the single molded piece may be mounted via the support;

means for pivotably mounting the single molded piece; and

a baffle for preventing direct view of an image source by an occupant eye.
