Abstract
A windshield wiper system (100) includes a pivoting wiper arm (110); a wiper blade (120) for wiping a surface (102); and a connector assembly (128) coupling the pivoting wiper arm (110) to the wiper blade (120), the connector assembly (128) comprising a gear drive (130) including at least one drive gear (132) and at least one positioning cog (136), wherein the gear drive (130) rotates the wiper blade (120) based on an angular position of the pivoting wiper arm (110) such that an arc of a motion path (320) of the wiper blade (120) is reduced.
Claims12
A windshield wiper system comprising:
- a pivoting wiper arm;
- a wiper blade for wiping a surface, and
- a connector assembly coupling the pivoting wiper arm to the wiper blade, the connector assembly comprising a gear drive including at least one drive gear and at least one positioning cog,
- wherein the gear drive rotates the wiper blade based on an angular position of the pivoting wiper arm such that an arc of a motion path of the wiper blade is reduced,
- wherein the pivoting wiper arm comprises a first arm member and a second arm member,
- wherein the gear drive comprises a first drive gear and a second drive gear, wherein the first drive gear is coupled to the first arm member and the second drive gear is coupled to the second arm member,
- wherein the gear drive comprises a first positioning cog and a second positioning cog,
- wherein the first and second positioning cogs are in engagement with the first and second drive gears,
- wherein the connector assembly further comprises a swing link coupled to the wiper arm,
- wherein, during operation, the wiper arm and the first and second drive gears rotate in a first direction at a first same speed rate, and
- wherein the swing link and the first and second positioning cogs rotate in a second direction opposite to the first direction at a second same speed rate which is higher than the first speed rate.
