TITLE OF THE INVENTION: HINGE AND DETENT MECHANISM ABSTRACT OF THE DISCLOSURE An improved hinge and detent mechanism is disclosed which is extremely reliable, provides a positive detent action and is very simple to manufacture. The biasing portion of the hinge and detent mechanism includes a one piece resilient plastic spring panel having flexible leg portions of either an S-shaped curvature or a generally M-shaped configuration, each of which includes oppositely inclined camming surfaces for engaging the hinge. The hinge structure includes a resilient bearing component which includes a pair of upstanding arm portions having grooves therein and into which an appropriately shaped hinge arm is press-fitted. The assembly provides an over-center action for holding the hinge structure in a closed position and also provides a continuously variable biasing force for main- taining the hinge in an open position.
