Windshield wiper blade
A connector assembly and wiper blade incorporating same having a base connector, having two longitudinal side walls, a first and second end, and a top surface extending therebetween, wherein the top surface has a pair of cantilevered beams, each provided with a locking tab, extending from a central portion towards each respective end of the base connector. The locking tabs are capable of engaging and securing an aperture in cap or wiper arm. The base connector further has a central recessed portion capable of receiving and securing a top wall of a side adapter. The base connector may further include a base support structure capable of securing the base connector to a wiper blade.

wherein a base support structure is provided proximate the bottom surface, the base support structure capable of securing the base connector to a wiper blade, and
wherein a contoured shelf is provided proximate the first end and faces towards the second end, the contoured shelf extending fully from the top surface to the bottom surface; and
a cap including
an aperture which can engage and secure the locking tab of the first cantilevered beam of the base connector, and
a contoured edge having a complementary shape with the contoured shelf, the contoured edge positioned adjacent to the contoured shelf as the locking tab is secured with the aperture, and the contoured edge extending fully from the top surface to the bottom surface of the base connector,
wherein the first cantilevered beam extends towards the first end of the connector, and the second cantilevered beam extends towards the second end of the connector, and wherein a first width, defined between the outer surface of the pair of wings adjacent the first cantilevered beam, is greater than a second width, defined between the outer surface of the pair of wings on the second end.
2. The connector assembly of claim 1 wherein the side walls of the base connector further comprise rests which are capable of supporting a wiper arm when the connector assembly is secured to a wiper arm.
3. The connector assembly of claim 1 wherein grooves are formed between the first and second cantilevered beams and the respective pair of wings adjacent to same.
4. The connector assembly of claim 1 wherein the base support structure comprises internal side walls having arcuate rivet clips that are capable of securing a rivet of a mounting base of a wiper blade.
5. The connector assembly of claim 4 wherein the base support structure further comprises transverse lateral walls which extend between and connect the internal side walls.
6. The connector assembly of claim 1 wherein the base connector comprises a cavity provided with projections that are capable of engaging and securing recesses in flaps of a side adapter.
7. The connector assembly of claim 1 wherein the side walls further comprise a one or more bottom recesses that are capable of receiving and securing a bottom projection in a side adapter.
8. The connector assembly of claim 1 further comprising a side adapter having a top portion and a side wall; the top portion comprising flaps having recesses which are capable of engaging projections in a cavity of the base connector.
9. The connector assembly of claim 8 wherein the side adapter further comprises a side wall with a bottom projection which engages a bottom recess of the base connector.
10. The connector assembly of claim 9 wherein the side adapter further comprises a rest which abuts the rest of at least one of the side walls of the base connector, and which is capable of supporting a wiper arm when the connector assembly connects to the wiper arm.
11. The connector assembly of claim 1 wherein the cap further comprises claws which engage a bottom of the side walls of the base connector.
12. The connector assembly of claim 1 wherein the cap further comprises spacers which each maintain a gap between the cap and a distal end of each of the wings or top surface of the base connector.
13. A wiper blade assembly comprising:
a wiper strip;
a force distribution structure; and
a connector assembly comprising:
a base connector, having two longitudinal side walls, a first and second end, a top surface extending between the first and second end, and a bottom surface opposite the top surface,
wherein the top surface comprises a first and second cantilevered beam, each provided with a locking tab, extending from a central portion of the top surface towards each respective end of the connector assembly,
wherein a pair of wings are adjacent to each of the cantilevered beams, each wing having an outer surface,
wherein a base support structure is provided proximate the bottom surface, the base support structure capable of securing the base connector to the force distribution structure, and
wherein a contoured shelf is provided proximate the first end and faces towards the second end, the contoured shelf extending fully from the top surface to the bottom surface; and
a cap including
an aperture which can engage and secure the locking tab of the first cantilevered beam of the connector assembly, and
a contoured edge having a complementary shape with the contoured shelf, the contoured edge positioned adjacent to the contoured shelf as the locking tab is secured with the aperture, and the contoured edge extending fully from the top surface to the bottom surface of the base connector,
wherein the first cantilevered beam extends towards the first end of the connector, and the second cantilevered beam extends towards the second end of the connector, and wherein a first width, defined between the outer surface of the pair of wings adjacent the first cantilevered beam, is greater than a second width, defined between the outer surface of the pair of wings on the second end.
14. The wiper blade assembly of claim 13 wherein grooves are formed between the wings and the cantilevered beams.
15. The wiper blade assembly of claim 13 wherein the base support structure comprises internal side walls having arcuate rivet clips that are capable of securing the rivet of a mounting base of a wiper blade, and transverse lateral walls which extend between and connect the internal side walls.
16. The wiper blade assembly of claim 15 wherein, the cap includes an aperture which can engage and secure at least one of the locking tabs of the connector assembly.
17. The wiper blade assembly of claim 13 wherein the cap further comprises claws which engage the bottom of the side walls of the connector assembly.
18. The wiper blade assembly of claim 13 wherein the cap further comprises spacers which maintain a gap between the cap and the ends of the wings or top surface of the connector assembly.
