A four bar linkage (46) supports a head-up-display (HUD) combiner (12) for movement between an upper storage position and a lower operating position. A stop and overcenter mechanism (28a,58;28b,52a;48,52) securely locks the combiner (12) in the operating position. A switch (60) is actuated by the linkage (46) when the combiner (12) is in the operating position.
