FIG. 7 shows the inclined portion 512, connecting walls 541 between the head 510 and the body 520, a notch flange 542, apertures 543, and a back pommel 544. As shown in FIG. 7, the head 510, the inclined portion 512 and the notch flange 542 are connected in series, whereby the inclined portion 512 is angled less than the head 510 and the notch flange 542. In other words, the head 510 and the notch flange 542 have a relatively rapid rise while the inclined portion 512 has a relatively slow rise. The notch flange 543 and a top portion of the connecting walls are part of the pommel 522. The apertures 543 run between the connecting walls 541 and the notch flange 542. The back pommel 544 runs parallel to the pommel 521. Also, the notch flange 543 is connected to the notch flange 533.
FIGS. 8 and 9 show the bracket 320, the adapter 500, and the windshield wiper arm 100 in an attached configuration. In such a configuration, the cutout notch 322 in the bracket 320 and the notch 521 in the adapter 500 are aligned and nested to receive and accommodate the rod 111 of the windshield wiper arm 100. Accordingly, the rod 111 is fitted snugly in the notch 521 of the adapter 500, and between the pommel 522 and the back 523, and the cutout notches 322 of the bracket 320 further participates in accommodating the rod 111 of the windshield wiper arm 100. For example, the cutout notches 322 engage the rod 111 at opposites ends of the rod 111. Additionally, in the configuration shown in FIGS. 8 and 9, the extension plate 112 of the windshield wiper arm 100 extends across the top surface of the back 523, and the platelet 113 is contacted to a lateral side of the adapter 500. Accordingly, the adapter 500 is made to fit between the platelet 113 and the head portion 110.
The invention thus being described, it will be obvious that the same may be varied in many ways. For example, an upper surface of each side wall of the bracket may have a notch formed therein if necessary to accommodate various adapters. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
