AN APPARATUS FOR CHATTERING-PREVENTION FOR WIPER OF VEHICLES

摘要

The present invention relates to a chattering prevention device for vehicle wipers. The chattering prevention device is arranged on vehicle wipers and prevents wiper blades from chattering. The chattering prevention device includes: an arm fixture which is formed on a side of a sliding groove to be fixed and installed on a side of wiper arms; a blade holder which has a clip unit fitted and coupled thereto while surrounding the periphery of the wiper blades and a connection unit formed to be extended and protrude from a side of the clip unit to be connected to a retainer and is coupled to a side of the wiper blades to correspond to the arm fixture; and the retainer which connects the arm fixture and the blade holder to each other and restricts a gap between the arm fixture and the blade holder to ensure robustness of the wiper blades in accordance with the rotation of the wiper arm. The chattering prevention device has the blade holder and the retainer fixed thereon and the arm fixture coupled through sliding to restrict the components and enable the upward and downward sliding movement for maintaining the reliable operation of the wipers. The chattering prevention device also reduces a kinetic energy difference between the front and rear ends of the wiper blades to alleviate chattering, thereby removing impurities from the vehicle glass more efficiently.
