Abstract: The present invention relates to a method for producing a wiper blade element (10) for a wiper blade and/or a wiper blade having a wiper blade element (10), in particular for a windscreen wiper. In order to provide simple and economical wiper blade elements and wiper blades having excellent properties, in particular having high wiping quality, high abrasion resistance, a high degree of friction reduction and miming noise reduction and a long service life, in said method a particle layer (12) is applied to an elastomer substrate (11), the elastomer substrate (11) is vulcanised with the particle layer (12) deposited thereon, and, after vulcanisation, a friction-reducing material (13) is applied to the particle layer (12). The invention further relates to a wiper blade element and wiper blade produced in such a way.

Abstract: Disclosed herein is a coupling apparatus for a wiper arm, which can provide firm coupling between a wiper blade and the wiper arm. The coupling apparatus comprises a blade coupling part provided to the wiper blade and including front and rear plates and having an opening defined at upper portions of the front and rear plates and a support shaft having a rectilinear plane formed at either side of the support shaft, and a wiper arm coupling part integrally formed at one end with the wiper arm and including a slant insertion mechanism to cause the wiper arm to be slantly inserted onto the support shaft and to hold the support shaft so as not to be separated from the slant insertion mechanism by changing an inclination of the wiper arm after the wiper arm is inserted onto the support shaft.
