Abstract

A connecting member (or members) for holding a windshield wiper blade member is formed to have a generally L-shape cross section comprising a short side and a long side, the free end of which is bent in a U-form for reinforcing the connecting member and for lowering air flow passing below it thereby to lessen lifting force acting on the wind shield wiper blade assembly when a vehicle is being driven in a high speed.

Claims

1. A windshield wiper comprising a blade assembly and connecting member attached to said blade assembly and having a short side and a long side in the transverse cross section to its longitudinal direction the long side of said member terminating at one end in a U-shaped bent portion bent in the same direction as the short side extends with the flat portions of said long side extending in parallel planes and the curved portion joining said flat portions substantially deflecting air impinging thereon so as not to impinge on said short side and not to lift said blade assembly.

2. A windshield wiper blade assembly comprising;

a first connecting member, a pair of second connecting members each one of which is pivotally connected to each end of said first connecting member, a blade member longitudinally slidably held by said pair of second connecting members, said first connecting member having a generally L-shaped cross section comprising short side and a long side, the edge of said long side remote from said short side being bent in a U-form with the flat portions thereof extending in parallel planes and the bending being in the same direction that the short side extends for reinforcing the mechanical strength of said first connecting member and for directing air flow passing underneath the same to substantially prevent air impinging on said short side.

3. A windshield wiper assembly as in claim 2 wherein said second connecting members have a generally L-shaped cross section comprising a short and a long side, the free end of said long side being bent in a U-form for reinforcing mechanical strength of said second connecting member and for directing air flow passing below the same.
