Lighted exterior mirror system

#This invention relates generally to security systems for vehicles and, more particularly, to remotely actuated, personal safety lighting systems. The invention is particularly adapted to incorporation in the exterior mirrors of a vehicle.

#Personal security in and around vehicles has become an important concern. In particular, an increasing number of assaults and robberies are committed in parking lots while occupants are entering and exiting vehicles. While remote-operated, keyless entry systems have been incorporated in vehicles in order to unlock the vehicle and illuminate interior lights, such systems merely expedite entry to the vehicle and do not, per se, enhance security around the vehicle. Accordingly, a need exists for a vehicle security system to increase the security for vehicle occupants while entering and exiting the vehicle. Any such system would need to be aesthetically pleasing and not burdensome in use.

#In order to include a security light system in a vehicle exterior mirror assembly, the security light must be rugged and resistant to environmental conditions such as water splash from road surfaces, rain and other precipitation as well as car washes. The assembly desirably must additionally be of relatively low cost and easy to manufacture in order to be acceptable to vehicle manufacturers. In addition, the security light desirably must be capable of matching a multiplicity of mirror housing designs. Moreover, the security light desirably is compact so as to fit into the interior cavity of conventional exterior mirror housings. For styling and aerodynamic reasons, exterior mirror housings are of determined and restricted size, shape, design, and interior volume. Moreover, the interior volume is already typically relatively cramped as it must accommodate not only the mirror reflector element itself and its movement, but also usually a manual or electric actuator that allows adjustment of the rearward field of view of the reflector remotely by the driver from the interior cabin of the vehicle. Also, since it is commercially desirable for a manufacturer of a security light to supply to a multitude of exterior mirror manufacturers, for their incorporation into their own particular exterior mirror assembly construction, it is desirable that the light be of a module type that is compact; that is weatherproofed; that is attachable and receivable by a wide variety of exterior mirror assembly designs; that is readily, standardly, and conveniently connectable to the vehicle electrical service and wiring already commonly found in conventional exterior mirror assemblies; and that is economic both for manufacture by the light module manufacturer and for the manufacturer of the complete exterior mirror assembly who will incorporate the light module into a mirror housing.

#Referring now specifically to the drawings, and the illustrative embodiments depicted therein, a vehicle personal security lighting system 25 includes an exterior mirror assembly 26 having a conventional reflectance element 28, a security light 30, preferably white, or clear, and a signal light 32, preferably red or red-orange, incorporated in a housing, or casing, 34. Casing 34 is connected by a neck 36 to a stationary panel or sail 38 adapted for incorporation with the forward portion of the vehicle side window assembly, and which mounts mirror assembly 26 to the door of a vehicle 40 (see FIG. 10). Reflectance element 28 may be any of several reflectors, such as glass coated on its first or second surface with a suitable reflective layer or layers, such as those disclosed in U.S. Pat. No. 5,179,471, the disclosure of which is hereby incorporated by reference herein, or an electro-optic cell including a liquid crystal, electrochromic, or electrochemichromic fluid, gel or solid-state compound for varying the reflectivity of the mirror in response to electrical voltage applied thereacross as disclosed in U.S. Pat. No. 5,151,824, the disclosure of which is hereby incorporated by reference herein.

#With reference to FIGS. 7 and 8, as is conventional, reflectance element 28 is mounted to a bracket 43 by a positioning device such as an actuator 42. Casing 34 is mounted to bracket 43. Actuator 42 provides remote positioning of reflectance element 28 on two orthogonal axes. Such actuators are well known in the art and may include a jackscrew-type actuator 42 such as Model No. H16-49-8001 (right-hand mirror) and Model No. H16-49-8051 (left-hand mirror) by Matsuyama of Kawagoe City, Japan, as illustrated in FIG. 7, or a planetary-gear actuator 42′ such as Model No. 540 (U.S. Pat. No. 4,281,899) sold by Industrie Koot BV (IKU) of Montfoort, Netherlands, as illustrated in FIG. 20. As is also conventional, the entire casing 34 including actuator 42, 42′ is mounted via bracket 43 for breakaway motion with respect to stationary panel 38 by a breakaway joint assembly 44. Breakaway joint assembly 44 (FIG. 9) includes a stationary member 46 attached to vehicle 40, a pivoting member 48 to which bracket 43 and casing 34 are attached, and a wire-way 50 through which a wire cable 52 passes. Wire cable 52 includes individual wires to supply control signals to actuator 42, 42′, as well as signals to control the level of reflectivity, if reflective element 28 is of the variable reflectivity type noted above, such as an electrochromic mirror. Power may also be supplied through cable 52 for a heater 53 as disclosed in U.S. Pat. No. 5,151,824 in order to evaporate ice and dew from reflective element 28.

#With reference to FIG. 5, actuator 42, 42′ receives a first set of reversible voltage signals from a switch 54, in order to bidirectionally pivot in one axis, and a second set of reversible signals from a switch 56, in order to bidirectionally pivot in the opposite axis, as is conventional. Switches 54 and 56 are actuated by a common actuator (not shown) that is linked so that only one of the switches 54 and 56 may be actuated at a time. In this manner, actuator 42, 42′ may utilize one common conductor for both switches 54, 56.
