A rearview mirror assembly comprising a fixed support structure, a movable mirror housing structure having a mirror unit adjustable mounted therein, and a spring-biased mounting assembly mounting the movable structure on the fixed structure (1) for spring-biased movement into a normal operating position wherein said movable structure extends laterally outwardly from the exterior of the vehicle where it is susceptible to the application of unwanted forwardly directed forces or unwanted rearwardly directed forces, (2) for movement forwardly through a forward range of movement out of said operative position in response to the application of unwanted forwardly directed force so that upon release of the force the spring bias is operable to return the movable structure to its operative position and (3) for movement rearwardly through a rearward range of movement out of the operating position in response to the application of an unwanted rearwardly directed force sufficient to overcome the spring bias which spring bias decreases to zero as the distance of rearward movement of the movable structure out of the operative position increases to an intermediate point within the rearward range of movement and thereafter reverses to bias the movable structure into a rearwardly folded limiting position. A power-driven assembly is provided for applying a yieldable force pattern to the movable structure to overcome the spring bias within the rearward range of movement so as to selectively move the movable structure between the operative and rearwardly folded limiting positions. |
