Wiper strip for use in windscreen wiper device of motor vehicle, has elastic middle part connected with wiper lip that is tiltable by deformation of middle part relative to fastening part, where middle part contains elastomer foam material

摘要

The wiper strip has a fastening part (1), a wiper lip (3), and an elastic middle part (2) connected with the wiper lip. The wiper lip is tiltable by deformation of the middle part relative to the fastening part, where the middle part contains elastomer foam material with higher hardness in an area limited at the fastening part than in an area limited at the wiper lip. The elastomer foam material has set of different layers. Limiting surfaces between two adjacent layers of the elastomer foam material is not even. The elastomer foam material exhibits a closed cellular structure.
