Abstract: The invention provides a bendable thermoplastic reinforcement for a profiled seal or profiled molding of a vehicle, such a profiled element including same and a method for producing the reinforcement. The reinforcement of substantially U-shaped cross section, has a central portion and two arms, each arm having over its length a series of limbs separated from one another by slots. Over at least one part of the length of the reinforcement, each limb has laterally an asymmetrical geometry and an area greater than that of each adjacent slot. The reinforcement is produced by extrusion of a thermoplastic material via a die of U-shaped profile formed between an extruder head and a receiving member for the material being discharged from the head which is provided with a hollow cavity designed to form directly said central portion, the slots and limbs, so that the extruded material progressively covers the receiving member.
