A wiper system is disclosed for a motor vehicle, and includes a longitudinally extended multi-part support having first and second longitudinally extended support arms. The second support arm is oriented in an imaginary extension to the first support arm and connected to the first support arm. A fastening element for fastening the support to a body of the motor vehicle is in each case arranged on the longitudinal ends, which face away from one another, of first and second support arm. A first wiper bearing is arranged on at least one of the longitudinal ends of first and second support arm.

A wiper subassembly for a motor vehicle has a windshield wiper retention member connected by a front connection arrangement in the longitudinal direction of the motor vehicle to a first bodywork component and by a rear connection arrangement to a second bodywork component. In order to optimize the crash behavior of a wiper subassembly, the front connection is arranged to be configured, when a threshold force which acts in the longitudinal direction between the windshield wiper retention member and the first bodywork component is exceeded, to give way so that the first bodywork component can be moved to the rear relative to the windshield wiper retention member.

Provided is a cleaning member, comprising an elastic member that includes polyurethane, wherein: when tan ? of a test piece sampled from the elastic member is measured in the temperature range of ?20? C. to +60? C., the peak temperature of a peak indicating the maximum value of tan ? is at 15.0? C. or below; the maximum value of tan ? is 0.20 to 0.55; tan ? at a temperature of 55? C. is 0.13 or larger; and where the detected quantity of all ions obtained when the test piece is heated at a rate of temperature increase of 10? C./second to 1000? C. using a direct-sampling mass spectrometer is M1 and the integrated intensity of a peak in a derived ion thermogram that corresponds to a range of m/z values originating in multifunctional isocyanate with at least three isocyanate groups is M2, M2/M1 is at least 0.001.
