Method for manufacturing a windshield wiper blade

Abstract

A method of manufacturing a windscreen-wiper blade for a motor vehicle is disclosed. The blade includes at least one mounting element in which a housing and an attachment rail are arranged parallel to the longitudinal axis of the mounting element, an elastically deformable spine arranged inside the housing of the mounting element, and a wiping strip, including a heel interlocked inside said rail of the mounting element. The method involves hot deformation of at least one longitudinal end of the mounting element, so as to immobilize the spine and the wiping strip longitudinally inside the housing and the rail of the mounting element, respectively.
