Claim:
A drive device ( 10 , 20 , 30 ) of a windshield wiping device, the drive device comprising a housing and at least one shaft ( 13 , 21 , 32 ) supported for pivoting movement relative to the housing, characterized in that one of a strip and a cord is wound about the at least one shaft ( 13 , 21 , 32 ) with a defined tension, the one of the strip and the cord having one end fixed relative to the housing and an opposite end, and in that an actuator engages the opposite end of the one of the strip and the cord, the actuator causing the one of the strip and the cord to move between a release condition, in which a force applied to the shaft by the one of the strip and the cord is reduced and the shaft is pivotable relative to the one of the strip and the cord, and a blocking condition, in which the force applied to the shaft by the one of the strip and the cord is increased to block pivoting movement of the shaft relative to the housing.
