Description

General windshield wiper seat combination structure

Technical Field

The present invention relates to a windshield wiper, and more particularly to a windshield wiper seat assembly structure capable of combining multiple windshield wiper driving arms.

Background

In general, the windshield wiper of an automobile needs to be arranged on the outer side surface of the glass of the automobile through a connecting windshield wiper driving arm set, and the driving arm applies acting force to the windshield wiper rubber strip so as to drive the windshield wiper to swing back and forth on the glass surface, thereby scraping off foreign objects such as rainwater or dirt on the glass surface.

Furthermore, the wiper driving arm is generally embedded and fixed on the base combination structure of the wiper. Since the types of the windshield wiper driving arms equipped in various automobile factories and automobile models are different, various windshield wipers are required to be matched with the windshield wiper driving arms of different types in design so as to be equipped with a specific base combination structure. In this regard, most windshield wiper operators use a plurality of base combinations to provide users with the option of assembling the corresponding base combinations. This not only causes an increase in the overall price of the wiper blade but also causes unnecessary waste of parts, and thus needs to be improved.

In view of this, the present inventors have made intensive studies and have made an effort to solve the above-mentioned problems in combination with the application of the theories, with respect to the above-mentioned prior art, and have made an object of improvement by the present inventors.
