A windshield wiper blade including an elongated, flexible wiper element having a spine and a tip portion for wiping action against a windshield surface. The spine includes at least one elongated reinforcing and retaining vertebra for restraining the wiper element into a desired longitudinal orientation. The vertebra has an elongated body defining a thin, generally rectangular cross-section. The body is formed of a plurality of generally parallel fibers extending longitudinally internally of the body. The fibers are maintained in tension by cured resinous material which defines the exterior dimension of the body.

[ I claim:] [10.] A windshield wiper blade assembly comprising:an elongated, flexible wiper element having a spine and a tip portion for wiping action against a windshield surface;a wiper superstructure including claws cooperatively engaging said spine of said wiper element at spaced locations along the longitudinal length thereof so as to mount said wiper element to said superstructure;said spine including a pair of opposed, longitudinally extending, laterally outward opening slots, each of said slots receiving a reinforcing and retaining vertebra for restraining said wiper element into a desired longitudinal orientation and for cooperating with said claw to mount said wiper element to said superstructure;each of said vertebra having an elongated body defining a thin, generally rectangular cross-section dimensioned to fit partially within said slots and partially extending laterally outward from said slots along the substantial longitudinal length of said wiper element and cooperatively engaged by said claws, each vertabra body being formed of a plurality of generally parallel fibers extending longitudinally internally of said body within a cured resinous material which maintains said plurality of parallel fibers in tension and defines the exterior dimensions of said body, and each of said vertebra allowing flexing of said wiper element in a direction generally perpendicular to the longitudinal axis of said wiper element and substantially along the length thereof while at the same time resisting flexing in a direction parallel to the surface to be wiped.
