Wiper blade with air deflecting device
First Claim
1. A wiper blade comprising a wiping element, at least one air deflecting device and a superstructure provided with a plurality of yokes characterized in that means are provided to secure the air deflecting device to at least one of the superstructure and wiping element of the wiper blade, said means comprising a resilient material and thereby permitting multi-dimensional movement of the deflecting device relative to the superstructure to facilitate conforming of the deflecting device to a surface to be wiped by the wiper blade, and said deflecting device has two spaced abutments at its lowermost extension, which abutments guide the deflecting device over a surface to be wiped.

Abstract
A wiper blade is provided and has a wiping element, a superstructure having at least two articulated elements and an air deflecting device secured to at least one of the elements by resilient members. Stops, runners or abutments are carried by the lower edge of the air deflecting device to hold the lower edge of the air deflecting device spaced from the surface to be wiped by a limited but defined amount. The resilient members hold the air deflecting device and, in particular, the stops, runners or abutments on the air deflecting device resiliently against the surface to be wiped as the blade is reciprocated across said surface.

- 13. A wiper blade comprising a wiping element, at least one air deflecting device and a superstructure characterized in that the air deflecting device has an elongate edge, first and second spaced abutments are provided on the elongate edge and means secure the air deflecting device to the superstructure so that the abutments can bear on a surface to be wiped and transmit substantially the entire force from the deflecting device to the surface, said abutment effectively guiding the deflecting device over the surface without binding with the surface.
