Title:
単軌二輪車用前照灯
Document Type and Number:
Japanese Patent JP4059770
Kind Code:
B2
Abstract:
The invention relates to a headlight unit for single-track two-wheeled vehicles, in particular motorcycles, motor scooters or similar, which incline about their longitudinal axis (X) when negotiating bends. Said unit comprises a sensor-controlled corrective device for the light beam pattern generated by the dipped low beam and has at least one central headlight (23) for driving in a straight line and one respective lateral headlight (22, 24) positioned to the right and left thereof; the right-hand headlight (22) is for illuminating left-hand bends and the left-hand headlight (24) for illuminating right-hand bends. Each respective lateral headlight (23) is rotated away from the horizontal position about its optical axis through an incline-compensation angle (ss), so that the outer edge that lies at a distance from the central headlight is in a lower position than the latter. The corrective device comprises an electronic control unit, which activates at least the central headlight (23) within a driving range for a substantially upright driving position and when bends are negotiated and a minimal tilting angle alpha is exceeded, deactivates the central headlight (23) and activates either the left-hand (24) or right-hand headlight (22).
