Definitions
- the present invention relates to a wiper blade for wiping a windshield of a vehicle.
- Wiper blades installed on vehicles such as automobiles are installed to wipe off rain, snow, insects, splashes from the front vehicle, etc., attached to the windshield to ensure the driver's view.
- the wiper blade is attached to the end of a wiper arm connected to an electric motor or the like, and reciprocates in a wiping range set on a window glass surface. Further, a spring is provided in the wiper arm, and the wiper blade is pressed against the wind glass surface by a pressing force transmitted from the spring via the wiper arm. In this manner, the wiper blade can wipe the window glass surface by the reciprocating swing and the pressing force by the wiper arm.
- the pressing force from the wiper arm needs to be distributed in the longitudinal direction of the blade wrapper in contact with the wind glass surface. Therefore, a dip blade in which a blade rapper and a wiper arm are connected by levers assembled in a plurality of stages has been developed, and the pressing force is dispersed through these repellers. Further, as disclosed in Japanese Patent Application Laid-Open No. 6-340249, a plate-like elastic member is attached so as to cover the back of the play wrapper, and a pressing force from a wiper arm connected to a central portion of the elastic member. A wiper blade has also been developed that disperses the water in the longitudinal direction of the play wrapper through an elastic member. This elastic member changes its width and thickness in the longitudinal direction, and applies a dispersion pressure to the blade wrapper according to the surface of the window glass to be wiped.
- this wiper blade has one elastic plate material attached to the blade wrapper, there is a possibility that the pressing force distributed to both ends is weaker than the pressing force applied to the central portion by being pressed by the wiper arm. is there. Also, by changing the width and thickness of the sheet material, the elastic force generated when it comes into contact with the wind glass surface, Since the pressing force to be dispersed is set, it is necessary to set the wiper blade according to the curvature of the window glass surface.
- the curvature of the window glass provided on vehicles often differs for each vehicle type due to design reasons, and it was necessary to set a dedicated wiper blade for each vehicle type. Therefore, the versatility of the wiper blade is reduced, and the manufacturing cost of the wiper blade may increase.
- An object of the present invention is to improve the versatility of a wiper blade for window glasses having different curvatures. Disclosure of the invention

- the wiper blade of this structure has the same structure as the conventional wiper blade. Even so, by changing the connection angle between the holding pieces according to the curvature of the window glass, the distributed pressing force can be averaged, and the versatility of the wiper blade can be improved. If the curvature of the window glass is so high that it cannot be handled simply by changing the connection angle between the holding pieces, it is possible to change to a holding piece having a different length dimension or to change the elastic coefficient of the elastic member. This can be dealt with by changing only the minimum necessary members.
- the wiper blade With the simple configuration of the wiper blade, the operation of the wiper blade is not hindered, the pressing force can be constantly dispersed on the blade wrapper on average, and the wiping performance can be stabilized.
- the wiper blade is configured simply Therefore, the manufacturing cost of the wiper blade can be reduced, and the height can be reduced and the size can be reduced. Furthermore, by changing the elastic modulus of the elastic member and the length of the holding piece, it is possible to follow the window surface with high curvature and complicated curved surface shape, and to easily reduce the dispersion pressure required for wiping. Can be obtained.
- the wiper blade of the present invention is characterized in that a radius of curvature of the holding piece assembly curved by the elastic member when the blade wrapper is separated from the window glass surface is smaller than a radius of curvature of the window glass surface. And thereby, the elastic member can be elastically deformed by bringing the wiper blade into contact with the wind glass surface, and the pressing force from the wiper arm can be dispersed in the longitudinal direction of the wiper blade.
- the wiper blade of the present invention is characterized in that the holding piece is molded in a state in which the elastic member is incorporated. As a result, manufacturing costs can be reduced.
- the wiper blade according to the present invention is characterized in that the elastic member comprises a plurality of members, and the holding members are connected to each other. This makes it easy to change the elastic coefficient of the elastic member.
- the wiper blade of the present invention is characterized in that it has an auxiliary member that positions and connects the plurality of elastic members in the longitudinal direction. As a result, the production cost can be reduced.
- the wiper blade according to the present invention is characterized in that the holding piece is formed to be gradually thinner toward another adjacent holding piece. Thereby, the wiping performance of the wiper blade can be stabilized without hindering the operation of the holding piece assembly.
- the wiper blade according to the present invention is characterized in that a holding claw for holding the blade wrapper is formed on the holding piece. This facilitates attachment and detachment of the wiper blade to and from the wiper blade.
