Side window deflector
A side window deflector has a body, and a flange joined to the body for fitting into a channel of a vehicle door window. At least one camming facet is formed on an inner surface of a deflector body end portion, adjacent a junction of an end portion lower edge and a flange lower edge. An advancing top edge of a window glass will encounter this camming facet before it encounters any other structure of the body end portion. Some embodiments have two camming facets. The camming facet eases the upward travel of the window glass into its channel. The main and end portions of the body have curved and recurved transitions to the flange, mitigating against bending stress.
