Technical Field
Aspects of the present disclosure relate to a reduced arc windshield wiper system that may be used in conjunction with a variety of different types of vehicles. As used herein, a vehicle is a motorized or non-motorized vehicle and may be, for example, a rail vehicle, a motor vehicle, a watercraft or an aircraft.
Background
Windshield wipers (also known as surface wipers) are devices used to remove rain, snow, ice, and debris from a surface such as a windshield. Almost all vehicles, including motor vehicles (e.g., cars and trucks), rail vehicles (e.g., railroad cars), boats and some aircraft, are often equipped with such wipers in accordance with legal requirements.
The wiper typically includes a wiper arm that pivots at one end and has a wiper blade attached proximate to the other end of the wiper arm. The wiper arm is powered by a motor (typically an electric motor), although pneumatic power is also used in some vehicles. The wiper blade rotates back and forth across the windshield, pushing water or other deposits from its surface. The speed of the wiper arm is typically adjustable, having several continuous speeds and typically having one or more intermittent settings. Most automobiles use two synchronized radial type arms, while many commercial vehicles use one or more four-bar linkage arms.
Disclosure of Invention
A first aspect of the present disclosure provides a windshield wiper system comprising: pivoting a 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 including a first connecting member directly coupled to the wiper arm and a second connecting member directly coupled to the wiper blade, wherein the first and second connecting members are movably coupled to each other, and wherein a position of the first connecting member relative to the second connecting member is based on an angular position of the pivoting wiper arm.
A second aspect of the present disclosure provides a vehicle comprising a windshield wiper system as described herein.

Detailed Description
To facilitate an understanding of the embodiments, principles and features of the present disclosure, they are explained below with reference to implementations in illustrative embodiments. In particular, they are described in the context of being a windshield wiper system for a vehicle. However, embodiments of the present disclosure are not limited to use in the described systems or methods.
The components and materials making up the various embodiments are described below in an illustrative rather than a restrictive sense. Many suitable components and materials that will perform the same or similar function as the materials described herein are intended to be within the scope of embodiments of the present disclosure.
Known windshield wiper systems include wiper arms that may leave an un-wiped area. For example, current wiper systems may trace a motion path having a large arc in a central region of the windshield, which tends to leave poor visibility where most needed in the central region (particularly the lower central region of the windshield).
The present disclosure provides an improved windshield wiper system, particularly a reduced arc windshield wiper system, which may be used in connection with many different types of vehicles. By varying the position, particularly the height, of the wiper blade as it traverses the path of travel (during the wiper stroke), the arc formed by the wiper blade may be reduced or reduced, thereby leaving less un-wiped area, particularly in the lower center area of the windshield and improving visibility.
