The present invention relates to headlights for self-propelled vehicles, especially for motor vehicles.
A headlight for a self-powered vehicle is described in German Published Patent Application 24 31 095 A1. This headlight has a reflector, which is pivotally mounted in a holder and which is adjustable by means of an adjusting mechanism. The adjusting mechanism has an eccentric adjusting element engaging eccentrically to a pivot axis of the reflector, which is connected with the reflector by a universal joint. This pivot joint is formed by a pin which has two ball ends so that the pin is pivotally engaged with one ball end in a spherical receptacle connected with the reflector and is engaged with the other ball end in another spherical receptacle provided with a threaded passage. A threaded portion of the adjusting element is screwed in the threaded passage. This double pivotal connection is required to minimize bending moments and/or transverse forces of the adjusting element, which can occur because of the pivoting motion of the reflector caused by the adjusting element. The known double-jointed pivot joint with the pin and both spherical receptacles requires comparatively many parts and takes up a comparatively large space, particularly in the adjusting direction of the adjusting element, because it requires the pin provided with the ball ends. This double-jointed pivot joint can be used only when there is enough room.
