Wiper arms for wiper system for wiping e.g. front window of motor car, have metal reinforcement provided with array of partial sections, where partial sections of metal reinforcement are arranged in form of lattice

摘要

#CMT# #/CMT# The wiper arms (100, 101) have a metal reinforcement provided with an array of partial sections, where the partial sections of the metal reinforcement are arranged in the form of a lattice. Fixing members (110, 111) are provided for attachment to a drive axle and joint parts (120, 121) for holding wiper blades (140, 141). A composite of a plastic material and the metal reinforcement are provided in a region of the fixing member and/or the joint part. The composite of the plastic material is made of a fiber reinforced or ball-strengthened plastic material. #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a wiper arm. #CMT#USE : #/CMT# Wiper arms for a wiper system, for wiping front and rear windows of a motor car. Can also be used for a disk of a vehicle or a device. #CMT#ADVANTAGE : #/CMT# The partial sections of the metal reinforcement are arranged in the form of the lattice, thus enhancing the wiper arms for the wiping system with a high and permanent dimensional stability, and hence preventing deformation of the wiper arms during the service life of the wiper arms with high loads. The composite of the plastic material and the metal reinforcement are provided in the region of the fixing member and/or the joint part, thus manufacturing the wiper arm in a simple and flexible manner, while reducing the weight and the cost of the wiper arms. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top perspective view of wiper arms of a wiper system. 100, 101 : Wiper arms 110, 111 : Fixing members 120, 121 : Joint parts 125 : Holder unit 140, 141 : Wiper blades.
