Abstract
Abstract A wiper device for reciprocating wiper blades over the screens of vehicle headlamps comprises fixed guides extending between the lamps and slidably carrying two carriages which respectively support rods carrying the wiper blades. A single driving motor drives a crank which angularly reciprocates a rod pivoted to the centre point of the guides, between the two carriages. The ends of this pivoted rod are themselves pivotably connected by respective links to the two carriages, and the links convert the angular reciprocation of the pivoted rod into sliding movement of the carriages. Each lamp has a washer jet which is fed by a pump operated automatically by the movement of one of the carriages.
