Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to the structure of wiper blades for vehicles, etc.

[Conventional technology]

Wiper blades attached to the windshield surface of conventional vehicles follow the curved glass surface of the window, so wiping is performed by following the two-dimensional cross-sectional curve of the windshield surface. Therefore, the conventional wiper blade 10 whose top view and side view are shown in FIGS. 4a and 4b has a clip 2.
A first lever 3 is connected to the wiper arm 1 by a pin 4 and pivotally attached to the clip 2 by a pin 4, a second lever 6 is pivotally attached to both ends of the first lever 3 by a pin 5, and a plurality of second levers 6 are connected to the wiper arm 1 by a pin 4. It is composed of a bucking 7 supported by each joint 6a and a blade rubber 8 attached to the bucking 7.
It is deformed so that the center part becomes higher by following the dimensional cross-sectional curve.

In addition, the wiper blade disclosed in Utility Model Application No. 53-129035 shifts the axis of the first lever and the axis of the second lever to bring the first lever closer to the window glass surface, thereby reducing the storage space during storage. At the same time, the resistance to wind pressure is reduced, but the blade rubber follows in the same manner as shown in FIGS. 4a and 4b.

[Problem that the invention attempts to solve]

In the above-mentioned conventional wiper blade, the blade rubber deforms in such a way that it follows the two-dimensional sectional view curve of the glass curved surface so that the central part becomes higher. When the wiper blade is stopped, the position of the wiper blade must be raised by the curvature of the wind lower molding added to the curvature of the wiper blade, which obstructs the driver's forward visibility. It has the disadvantage of becoming

[Means for solving problems]

In the wiper blade of the present invention, each of the levers and the blade rubber attachment member constituting the wiper blade has a curvature approximately equal to the curvature of the blade lower molding.

[Effect]

Therefore, each blade and the blade rubber attachment member constituting the wiper blade are curved along the window glass surface with a curvature approximately equal to the curvature of the wind lower molding, so when the wiper is stopped, the wiper blade is are located directly above the wind lower molding in parallel with almost the same curvature, ensuring a wide field of view for the driver.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1a and 1b are a top view and a side view of an embodiment of the wiper blade of the present invention. The parts and parts names constituting the wiper blade are the same as those shown in FIGS. 9
The radius of curvature R in the window glass surface direction is approximately equal to the curvature of the window lower molding 11.
Therefore, as shown in FIG.
The driver's forward field of view is expanded because the vehicle is located almost parallel to the curve.

Figure 3 shows the wiper blade 1 of this invention on the passenger side.
0 is a diagram showing the wiping range of the front window when a conventional wiper blade is attached to the driver's seat side. This diagram clarifies the difference in the forward field of view between the two.

In addition, in the case of a single wiper, if the curvature of each lever of the wiper blade 10 at the stop position is matched to the curvature of the wind lower molding 11, the field of view is expanded and the appearance is good. Furthermore, since the wiper blade 10 has a curvature, the blade lip does not reverse all at once during reversal, thereby reducing reversal noise.

[Effect of idea]

As explained above, the present invention provides a wiper that includes a first lever pivotally connected to a wiper arm, a blade rubber support member and a blade rubber attached to a plurality of branch levers pivotally connected to both ends of the first lever. By making the curvature of each blade lever and blade rubber attachment member approximately equal to the curvature of the windrow lower molding, the driver's field of view is expanded, the appearance is improved, and the force that acts when the wiper blade is reversed is reduced. This has the effect of making it smaller and making reversal easier.
