Abstract
The invention proposes a motor vehicle windscreen wiper of the type in which a cover, intended completely to cover over a drive head, includes two longitudinal lateral flanks joined together by a transverse back which includes an upper longitudinal part and a downwards-curved part at its rear end. The transverse back of the cover includes an aperture giving access to means for fixing the drive head onto the end of an alternating-sweep drive shaft. A cap is provided, the contour of which is complementary to that of the aperture, which is mounted articulated on the cover between a service position in which it blocks off the aperture and an open raised position in which the aperture is clear.
Claims36
A motor vehicle windscreen wiper comprising:
- a cover for completely covering an alternating-sweep drive head for a windscreen wiper blade with respect to which it is mounted articulately about a transverse axis, between a service position and a raised position, the cover comprising two longitudinal lateral flanks joined by a transverse back having an upper longitudinal part and a downwardly-curved part at a rear end, the transverse back of the cover having an aperture for giving access to means for fixing the drive head onto the end of an alternating-sweep drive shaft;
- and
- a cap having a contour complementary to a contour of the aperture, the cap being mounted articulated on the cover between a closed service position in which the cap blocks off the aperture and an open raised position in which the aperture is clear,
- a means for articulating the cap onto the cover comprising an articulation tab with a circular-arc profile and a concave upper face, the tab being slidably guidance in an arcuate guide slot with a profile complementary to the profile of the tab.
