Windscreen wiper device
View Patent ↗A windscreen wiper device includes an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material. The wiper blade includes a wiping element which can be placed in abutment with a windscreen to be wiped, which wiper blade includes a central longitudinal groove, in which groove a longitudinal strip of the carrier element is disposed. The windscreen wiper device includes a connecting device for an oscillating arm, wherein the oscillating arm is pivotally connected to the connecting device about a pivot axis near one end thereof. The wiping element is movable in a direction at least substantially perpendicular to a windscreen to be wiped, dependent on the pressure exerted by the longitudinal strip on the wiper blade.
1. A windscreen wiper device comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, the wiper blade comprising a wiping element which can be placed in abutment with a windscreen to be wiped, which wiper blade includes a central longitudinal groove, in which groove a longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for an oscillating arm, wherein the wiping element is movable relative to said longitudinal strip of said carrier element in a direction at least substantially perpendicular to a windscreen to be wiped, dependent on the pressure exerted by the longitudinal strip on the wiper blade, and wherein said groove extends in a downward direction beneath the longitudinal strip to form a longitudinal hollow channel defined by said longitudinal strip and a bottom of said groove, wherein said bottom is flexible, and wherein said wiping element is allowed to move relative to said longitudinal strip of said carrier element in a direction perpendicular to a windscreen to be wiped, dependent on the pressure exerted by the longitudinal strip on the wiper blade due to the resiliency of said bottom.
2. A windscreen wiper device according to claim 1 , wherein the wiping element is resilient between a first position facing away from the longitudinal strip and a second position facing towards the longitudinal strip.
3. A windscreen wiper device according to claim 2 , wherein the wiping element is in the first position at a pressure A exerted by the longitudinal strip on the wiper blade, wherein the wiping element is in the second position at a pressure B exerted by the longitudinal strip on the wiper blade, and wherein pressure A is smaller than pressure B.
4. A windscreen wiper device according to claim 1 , wherein the groove also extends in upward direction above the longitudinal strip for forming a longitudinal hollow channel defined by the longitudinal strip and an upper surface of the groove.
5. A windscreen wiper device according to claim 4 , wherein the wiper blade is provided with a spoiler at a side thereof facing away from a windscreen to be wiped.
