HEADLIGHT WIPER

摘要

A headlight wiper is described comprising a support ring to be mounted in a stationary position on a headlight, a carrier ring rotatably mounted on the support ring, and a wiper arm which is pivotally mounted in the carrier ring and provided with a driver cooperating with a stationary guide on the support ring. The carrier ring is provided with a tooth rim adapted for engagement with a motor operated pinion. The arrangement is such that when the wiper is started the wiper arm will be swung from a substantially tangential rest position to a substantially radial working position in which it will move along the lens of the headlight through the rotary movement imparted to the carrier ring. According to the invention the stationary guide is formed by a guide groove in the support ring and a portion of the driver projects into the groove for permanent engagement therewith. Said guide groove comprises a portion which extends along a spiral line and, at its inner end, terminates in a continuous circular groove portion in the support ring.
