WINDSHIELD WIPER ASSEMBLY HAVING SPLINE LOCK COUPLER

摘要

The present invention relates to wiper assembly that includes a wiping element adapted to contact a surface and having head portion and a wiping portion, a pair of supporting elongated splines each having at least one aperture, and a coupler with a base portion, a pair of side walls, at least one pair of claws facing each other that have an upper element extending laterally inwardly terminating to define a channel between the claws to receive the head portion of the wiping element, a lower element spaced below the upper element, and a retention gap defined therebetween with the splines at least partially disposed therein, and at least one pair of resilient locking tabs extending laterally inwardly from the side walls and being disposed in the apertures of the splines so as to independently retain the splines with respect to the coupler and independently space the splines laterally with respect to each other.

1. A wiper assembly comprising:
a wiping element adapted to contact a surface to be wiped, said wiping element having a head portion and a wiping portion; a pair of elongated splines acting to support said wiping element, each of said splines having at least one aperture; and a coupler having a base portion, a pair of side walls extending from said base portion, at least one pair of claws formed on each of said side walls and facing each other; each of said claws having an upper element extending laterally inwardly and terminating to define a channel between said claws to receive said head portion of said wiping element; a lower element spaced below said upper element and extending laterally inwardly; a retention gap defined between said upper element and said lower element with said splines at least partially disposed therein, and at least one pair of resilient locking tabs extending laterally inwardly from each of said side walls to an end, said locking tabs being disposed in said apertures of said splines to independently retain said splines with respect to said coupler and independently space said splines laterally with respect to each other.
