Windscreen wiper device
View Patent ↗A windscreen wiper device comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one longitudinal groove, in which groove at least one longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for an oscillating arm, wherein said oscillating arm is pivotally connected to said connecting device about a pivot axis near one end thereof, with the interposition of a joint part, wherein said wiper blade comprises a spoiler at a side thereof facing away from the windscreen to be wiped, characterized in that a free end of said spoiler, facing towards an A-pillar of the windscreen to be wiped, is provided with a beveled surface, seen from the windscreen to be wiped.
1. A method of installing a windscreen wiper device on a windshield of a vehicle that has an A-pillar, comprising the steps of:
making a wiper blade made of an integral piece of elastomeric material and extending with an at least substantially constant cross-sectional shape between opposite longitudinal ends, the wiper blade including a lower wiping portion for sealing against a windscreen, the wiper blade further including an upper holding portion interconnected with the wiping part by an integral tilting web portion, and the holding portion including a longitudinal groove and a spoiler which faces away from the wiping portion;
inserting a longitudinal strip of a carrier element into the longitudinal groove of the wiper blade;
firmly attaching a connecting device to the wiper blade and strip;
cutting the spoiler of the wiper blade adjacent at least one of the longitudinal ends to provide the spoiler with a bevelled portion that has a bevelled surface and wherein a height of the wiper blade along the bevelled surface decreases towards the adjacent longitudinal end for avoiding contact between the spoiler and an A-pillar on a vehicle and wherein, after cutting, the longitudinal groove of the wiper blade remains open at the at least one of the longitudinal ends of the wiper blade;
attaching the connecting device with an oscillating arm; and
contacting the wiping part of the wiper blade with the windshield such that the bevelled portion of the spoiler at least partially rests underneath the A-pillar of the vehicle.
2. The method as set forth in claim 1 wherein the step of cutting the spoiler is further defined as cutting the spoiler of the wiper blade adjacent each of the longitudinal ends.
3. The method as set forth in claim 1 wherein the elastomeric material is rubber.
4. The method as set forth in claim 1 wherein the step of attaching the connecting device to the wiper blade and strip includes mounting the connecting device around the spoiler without damaging the spoiler by engaging clamping members on the connecting device around longitudinal sides of the wiper blade that face away from each other.
5. The method as set forth in claim 1 wherein the groove is generally rectangular in shape and with a raised area for reduced friction between the wiper blade and the longitudinal strip.
6. The method as set forth in claim 1 wherein a ratio of the height of the wiper blade outside of the bevelled portion and the height of the wiper blade in the bevelled portion is between 1.5 and 8.
7. The method as set forth in claim 1 wherein, in a final form, the longitudinal ends of the wiper blade further are free of end caps.
8. The method as set forth in claim 1 wherein the step of making the wiper blade is further defined as extruding the wiper blade.
