AI Technical Summary

Technical Problem

Existing wiper blades for motor vehicles struggle to maintain optimal contact with strongly curved windshields, leading to suboptimal wiping performance.

Method used

A wiper blade design incorporating a spring element made of a different elastic material, such as spring steel, between the wiper lip and support section, along with a wind deflector element and a reinforcing metal rail, to distribute contact force evenly and ensure consistent contact with the windshield, enhanced by airflow assistance.

Benefits of technology

Ensures clean and uniform contact with curved windshields, improving wiping performance and extending the wiper blade's service life through stable and efficient force distribution.
