Spacer for a vehicle windscreen wiper

The wiper has a wiper blade (1), which is raised when in parked position. A slide rail (2) with trailing slide edge (7) is positioned on the side of the wiper facing the parking position, and parallel to the wiper blade. The distance between sliding edge and glass is dimensioned, so that in parking position the slide rail engages on a ramp-like wedge-shaped parallel shoulder (8). The size of the shoulder decreases in direction towards the glass (6), and the rail moves with its slide edge along the rising slide edge (9) of the shoulder along a defined path into parking position, so that lifting of the wiper blade is secured.
