Retracting head up display with fine adjustment of combiner
First Claim
1. In a motor vehicle having an adjustable head up display including a reflecting element for movement between a stored position out of a line of sight of an operator, and an operating position in the line of sight of the operator, comprising:
- display means for projecting an image to the reflecting element when in operating position, thereby presenting the image at a position viewable by the operator;
a hinged support bearing the reflecting element; and
a manually operated mechanism connected to the hinged support for moving the hinged support and the reflecting element between stored and operating positions, the manually operated mechanism including means for fine adjustment of the hinged support and the reflecting element to adjust the image at an imaging position, wherein the manually operated mechanism further includes an input element with a first degree of freedom for translation and a second degree of freedom for rotation with movement of the input element in the first degree of freedom for translation causing movement of the hinged support and reflecting element between stored and operating positions, and movement of the input element in the second degree of freedom for rotation effecting fine adjustment of the reflecting element when in the operating position.

Abstract
A combiner is pivotally mounted for movement between an operating position in the line of sight of an operator and a storage position. A sector gear fixed to the combiner engages a slidable rack so that sliding the rack causes pivotal movement of the combiner. A control knob and stem are mounted for rotary movement and translation. A cam rotated by the knob engages followers on the rack to slide the rack upon knob translation or rotation. Knob translation effects movement of the combiner between operating and storage position, and when in operating position, knob rotation effects fine adjustment of the combiner to adjust image position.
