Abstract
A system for correction of the orientation of a motor cycle headlamp includes a weight which moves in dependence on the centrifugal force caused by a turning movement of the motor cycle. In one embodiment, the weight is mechanically linked by transmission chains to control the correcting movement of the headlamp. In another embodiment, the correcting movement is carried out electrically under the control of a transducer which senses the extent of movement of the weight.
Claims18
A headlight for use with a two-wheeled vehicle, such as a motorcycle, having a body and handlebars pivotable with respect to the body, the headlight comprising:
- a frame fixed with respect to the handlebars of the vehicle
- light-projecting means carried by said frame, said light projecting means having an optical axis along which light is projected therefrom,
- support means for rotatably supporting said light-projecting means with respect to said frame, said light-projecting means being rotatable about an axis extending in a front-to-rear direction of said light-projecting means and at a small acute angle to said optical axis, and
- means operative when the vehicle makes a turn for rotating said light-projecting means about its axis of rotation from the position it occupies when the vehicle is upright and traveling in a straight line, the amount of rotation at any moment being a function of the angle of inclination which the vehicle makes at that moment with the vertical.
