Title (EN) WINDSCREEN WIPER DRIVING MECHANISM
(FR) MECANISME MOTEUR POUR UN ESSUIE-GLACE
Abstract:
(EN) A wiper driving mechanism includes a yoke member (5) driven by a rotary crank which in turn drives a pair of symmetrical arms (14, 15) each of which drives a wiper blade (17). Either the two arms (14, 15) are connected in parallel and drive one wiper blade (17) in a pantograph motion or separate unconnected blades carry out an arcuate sweep over a wider area. The arrangement enables a smooth motion approximating to simple harmonic motion to be achieved, and this then enables shock loads to be reduced at the ends of travel.
(FR) Un mécanisme moteur pour un essuie-glace comprend un élément en forme de croix (5) entraîné par un mécanisme de manivelle tournante et entraînant deux bras symétriques (14, 15) portant une lame (17) essuie-glace. Les deux bras (14, 15) sont reliés en parallèle et portent une lame (17) essuie-glace à la manière d'un pantographe ou ils portent chacun une lame séparée, ce qui permet un mouvement de balayage courbe sur une surface plus importante. Ce système permet un mouvement en douceur se rapprochant d'une oscillation sinusoïdale simple, qui diminue les à-coups en fin de course.
