Abstract

The piston of a reciprocating wiper system on which a wiper arm is mounted is guided to be linearly displaceable in a capshaped bearing and has a slide which is longitudinally guided by two guide elements fixed to the housing. To achieve jam-free guidance on the guide elements without adjustment, the slide is guided with a capshaped bearing on one guide element in a closed manner. In contrast thereto there is a play between the slide and the second guide element in the plane defined by the guide elements.
