Abstract

An automotive windshield wiper connection device has a body which is provided with a hook-type elastic piece, an insertion-type elastic piece, a pin hole, and a locking slot. The hook-type elastic piece is provided thereover with a rotary cover pivoted therewith for engaging a hook-type rocking arm. The insertion elastic piece is provided thereover with an insertion hole for engaging an insertion-type rocking arm. The connection device is thus compatible with the windshield wiper rocking arms of motor vehicles of various models.

1. An automotive windshield wiper connection device comprising:

two side plates parallel to each other and each provided in the center of a bottom thereof with a pin hole and a locking slot;

a connection portion connecting said two side plates and provided at one end with an insertion-type elastic piece and at another end with a hook-type elastic piece, said insertion-type elastic piece being provided with an insertion hole, a retaining hole being located over said insertion hole, one of said side plates being provided with a first elastic pad located at one side of said retaining hole, and said one of said side plates being provided with a second elastic pad located over a place between said pin hole and said locking slot, said elastic pads extending above said connection portion in an un-flexed condition, said connection portion being provided with a cover fixing slot located in proximity of said hook-type elastic piece, said side plates each being provided with a protrusion and a recess located at an outer end thereof; and

a cover having a cover pin by which said cover is pivotally engaged to said cover fixing slot, said cover being provided with a strength retaining point and a retaining point corresponding respectively to said protrusion and said recess of said connection portion;
