A low profile, flexible windshield wiper assembly has a frame (10) constructed from flat sheet spring steel. The frame (10) attaches to a semi-rigid spline (50) at distinct pressure points, while the spline (50) supports a rubber wiping blade (60). At least some of the pressure points are located at the end of cantilevered fingers (18) formed in the frame (10) so that the spline (50) may flex independently from the frame (10). The cantilevered fingers (18) allow semi-pivotable portions of the frame to flex independently from the rest of the frame to enhance curve conformance on a windshield. The frame (10) attaches along the center of the spline (50) while the blade (60) attaches along the edges of the spline (50). The present invention allows the pressure points to be efficiently formed out of the frame material.
Ensemble d'essuie-glace souple et surbaissé, muni d'un montant (10) de tôle plate en acier à ressort. Ce montant (10) est relié à une languette semi-rigide (50) par un certain nombre de points de pression distincts, et cette languette (50) soutient une lame d'essuie-glace en caoutchouc (60). Certains de ces points de pression se trouvent à l'extrémité de doigts en porte-à-faux (18) formés dans le montant (10), grâce auxquels la languette (50) est en mesure de fléchir indépendamment du montant (10). Ces doigts en porte-à-faux (18) permettent à des sections susceptibles de pivoter à demi de fléchir indépendamment du reste du montant pour mieux s'adapter à la courbure du pare-brise. Le montant (10) est relié au centre de la languette (50), tandis que la lame (60) est reliée à ses bords. Cette invention permet la création efficace de points de pression à l'extérieur du matériau du montant.
