Abstract

1,241,819. Vehicle headlamps. ROBERT BOSCH G.m.b.H. 13 Nov., 1968 [17 Nov., 1967], No. 53824/68. Heading F4R. The attitude of a vehicle headlamp is adjusted by a motor acting through an eccentric pivot on the headlamp. A motor 18. is mounted on the reflector 30 of the headlamp and drives gearwheel 33 through worm 32. Gear-wheel 33 is secured to the reflector by a rod (34, Fig. 2, not shown) and has an eccentric pin 36 mounted thereon. The pin is linked 35 to a fixed pin 38 (42) secured to a screw 46 by a support 43. The link 35 is greater or less by half the total adjustment provided for the headlamp than the distance of the pin 36 from the axis 31 of the worm 32. A screw 46 provides for initial adjustment of the headlamp. Linked to pin 38 is an arm 24 pivoting at 49 on cranked member 50 which is connected to the edge 51 of the reflector. The arm 24 carries a conductive portion (25, Fig. 4, not shown) which makes electrical connection between the motor 18 and switches sensing the vehicle load. In operation, a sensor on the vehicle springs closes one of four switches according to the size of the load thereby supplying current to one of the four conductive tracks 19, 21, 22, 23 associated with the conductive portion (25) of arm 24 (Figs. 3 and 4, not shown). The motor is actuated and moves the adjusting mechanism including arm 24 until the conductive portion meets one of the non-conductive portions 26, 27, 28, 29 and thereby stops the motor. A switch may be provided to allow the adjusting mechanism to work only when the vehicle is stationary. In another embodiment (Fig. 5, not shown) a Wheatstone bridge having two variable resistors one varied by the motor and the other by the suspension, is used to adjust the inclination of the headlamp. Manual alteration of the headlamp may be achieved by a switch located on the dashboard.
