Abstract
Abstract 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.

Claim 8
Dependent Claim
69 words
An assembly as in claim 6, in which the linkage means is dimensioned such that the distance between the second joint means and the third joint means is smaller than the sum of the distances between the second joint means and the fourth joint means; and between the third joint means and the fourth joint means; when the secondary link and the connecting link are in said overcenter position.
Claim 9
Dependent Claim
35 words
An assembly as in claim 7, further comprising a switch means which is integrally movable with the secondary link and is actuated by the fourth joint means upon abutment thereof against the secondary stop member.
