Abstract

PURPOSE:To make it possible to simply and certainly remove ice and snow or an oil film attaching to a windshield or the like by forming a layer made of conductive and elastic heating material at least on the tip of a blade body, and utilizing the heating action of said material. CONSTITUTION:A blade body 1 is composed of a base 1a held by holding metal fittings 2, a neck 1b protruding from said base 1a and being free-bendable right and left, and a core 1c formed on the tip of said neck 1b in about triangle- shape cross section. In this constitution, a layer which is made of conductive and elastic low resistance material and becomes gradially thinner from the neck 1b toward said tip is formed over the whole outer surface of the core 1c. Conductive elastomer such as conductive rubber and resin or the like is used as the conductive and elastic material 3. The heating action due to Joule heat of said material 3 can be therefore improved to simply and certainly re move ice and snow or an oil film attaching to a windshield or the like.

Another branch stay is pivotally attached to the end of each branch stay near the blade center, and the elastic blade is held by a flexible gripping frame supported by the six-point support of these branch stays. It is.

ドライバーの視界を悪くするなどの欠点があった。When such conventional wiper blades are applied to the windshield of a car that is driven in an area with wet snow such as blizzards or flecks of snow, the wiper blade arm swings due to the snow firmly adhering to the windshield. The problem was that the angle of movement was gradually narrowed, worsening the driver's visibility. Furthermore, if an oil film adheres to the windshield of a car while the vehicle is in motion, the wiper blades cannot remove it completely, causing the windshield to fog up, which also impairs the driver's visibility.

It is an object of the present invention to provide a wiper blade that can perform the following functions.

This will melt the snow that has adhered to it or decompose and remove the oil film.

) and a neck (1b) that can be bent left and right, and a blade core (1C) with a substantially triangular cross section formed at the tip of the neck (1b). Blade core (1
The outer surface of C) has a neck (1b
) A conductive elastic material (3) having a low resistance is formed so as to become gradually thinner from the side toward the tip end. Conductive elastic material (3
), a conductive elastomer such as conductive rubber or conductive resin is used. The reason why the conductive elastic material (3) is made gradually thinner from the neck (1b) side to the tip side is because the electrical resistance on the tip side of the conductive elastic material (3) increases in inverse proportion to the cross-sectional area. This is to enhance the heat generation effect due to Joule heat. In addition, instead of covering the outer surface of the blade core (1C) with the conductive elastic material (3) as in this example, the main body (1) of the blade has a substantially triangular cross section as shown in the third figure. It may be formed into a shape and a conductive elastic material (3) may be formed at the tip thereof.
