Abstract
Various embodiments of a device for connecting a flat wiper blade to various wiper arms are provided. In one embodiment, the connecting device includes: a joint fixed to a frame of a flat wiper blade; a bracket snap-mounted on the joint; and an adaptor mounted to the bracket. The bracket has a pivot shaft extending perpendicular to a length direction of the frame and having a pivot bore therethrough. The adaptor has a pair of side wall portions. Fitting apertures are perforated in the side wall portions. The adaptor is mounted to the bracket in such a manner that both ends of the pivot shaft are fitted to the fitting apertures. The adaptor is configured to be suitable for differently-configured distal ends of the wiper arms. The connecting device connects a single flat wiper blade to various wiper arms.
