Abstract
An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a first end of the wiper arm, and an output shaft coupled to a second end of the wiper arm. The wiper blade includes a support member coupled to a blade element through a clip and a fastener extending through the blade element. The support member can be made from a composite material and the clip and fastener allow for attachment of the blade element to the support member without piercing the support member.
Claims19
A wiper blade for use on a windshield of an aircraft, the wiper blade comprising:
- a support member coupled to a blade element;
- a clip coupled to and surrounding at least a portion of the support member and at least a portion of the blade element, wherein the clip comprises:
- a first side surface, a second side surface, a top surface, a first partial bottom surface, and a second partial bottom surface;
- wherein the first partial bottom surface extends from the first side surface inward toward a center plane of the clip and the second partial bottom surface extends from the second side surface inward toward a center plane of the clip and toward the first partial bottom surface;
- and
- wherein at least a portion of each of the first partial bottom surface and the second partial bottom surface are parallel with at least a portion of the top surface;
- a fastener extending through the blade element and the clip, wherein the fastener secures the clip to the blade element;
- and
- a coupler coupled to and surrounding at least a portion of the support member and at least a portion of the blade element.
A windshield wiper system for use on a windshield of an aircraft, the windshield wiper system comprising:
- a wiper comprising a wiper arm and a wiper blade coupled to a first end of the wiper arm, the wiper blade comprising:
- a support member coupled to a blade element;
- a clip coupled to and surrounding at least a portion of the support member and at least a portion of the blade element, wherein the clip comprises a first side surface, a second side surface, and a top surface extending between and connecting the first side surface to the second side surface, the top surface includes a curved surface and a flat surface, wherein the curved surface of the top surface is adjacent and contacts the support member;
- and
- a fastener extending through the blade element and the clip, wherein the fastener secures the clip to the blade element;
- and
- an actuator comprising an output shaft, wherein the output shaft is coupled to a second end of the wiper arm, and wherein the actuator is configured to oscillate the output shaft to sweep the wiper in an arc across the windshield of the aircraft.
