Claims (5)

X 2 side-flowing wind currents act by claims: they press the wiper down onto the windshield to make it more firmly in working contact 1. Swivel arm for wiper with one to hold with the windshield. The guide surface, designed as a fin for the airflow sweeping past, is either un-fl provides a characteristic resistance by drawing with a that the guide surface (8, 2M) is set on the pivot in a support lowering, which the wiper arm (4), most of its length to the guide surface in moderate winds in its usual, occupying, sitting and moving back relative to the arm between the inoperative position, in the case of considerable see two positions is movable, which allows the wind speeds to take effect. Provide suitable inclinations for airflow if it hits one side or the other of the arm during one of the pivot pins in a spiral spring. the end wall of a connector is seated 2. Swivel arm for windshield wipers on »5 other pivot pins in an attachment of an auxiliary bracket Claim 1, characterized in that the Uu set. ßcrc part of the swivel arm is a metal strip (2) Another suggestion that has become known is and that wiper blade is placed on the outer surface of the strip (2) on a plate to anpreßdruekerhöhu. which stands on the holding arm of the sheath and a squeegee is to be attached to the free end of the arm in such a way that the width of the driver and a curved cross wind act frontally on the plate, which has a hinge. has a cut so that the air flow pulls it is concave with respect to the driving wind in any windward surface (18), whereby the guide can be adjusted; A clamping device is used for this setting on the arm by means of two fastenings. The plate surface should also (15, 17) have a wedge-shaped E-elevation at its inner and outer end so that it is fixed, the inner attachment (15) a relative air evenly up and down on the ves pivoting and the external fastening surface acts,
allows relative sliding across the arm. However, practice has shown that in this case 3. Pivoting for windshield wipers after changing the vehicle did not generate airflow, as discussed 1, characterized in that the Leit 30 main. near the windshield sinking surface (20) is flat and runs along a longitudinal axis (22) right to this, but extends in some direction is attached to the arm (2). so that the distance from the windshield divides, the they of the air flow on one or the other effect of this part flow from the individual construction side can be blown, the tilting units including the body shape and the movement is limited by stops (24). 35 Depending on the wipe shape, without the desired Anwelche the baffle to generate a correct compression pressure for the air flow. Allow sloping surface to offer. The invention has set itself the task to 4. Swivel arm for windshield wiper after approaching, avoid that the end of the wiper is near the claim I to 3, characterized in that the guide surface is printed on the disc and that of the Guide surface (8, 20) shear off one end from the disc which is inwardly remote from the guide surface is pressed towards extending actuating finger. It solves this problem in that the has, whose lateral movement is the tilting movement of the guide surface on the wiper arm, for the most part caused by the guide surface. occupying its length sits and relative to that 5. Swivel arm for windshield wiper can be moved between two positions after an arm. the dem Claim 3, characterized in that the air flow by 45 offer suitable inclinations when it is on a longitudinal axis movable guide surface (20) hits one side or the other of the arm. As a inwardly extending spindle with a further advantage results in a Kostcner gear connection one with the wiper savings, because the guide surface is not used with every replacement shaft concentric flywheel drive can be changed by being a wiper blade with r.js the guide surface in one or the other row 50 must. is tilted. The r.ußerc ^T c il of the pivot arm may be a metal strip and the voltage applied to the outer surface of the strip of thin sheet guide surface exist and to the free hand of the arm 55 increasing width and have a curved cross-section, so that the surface facing the air flow The invention relates to a swivel arm for is concave, the guide surface on the arm by means of Windshield wipers with one of the two attachments passing by on its inner and outer Airflow offering an inclined surface and it is fixed at the end, the inner fixing a relative pressing the windshield wiper against the wind swivel 60 and the outer attachment a relative protective disc utilizing guide surface. sliding across the arm is permitted. It is a guide surface for a windshield wiper. The guide surface is expediently flat and around a known, which attached the longitudinal axis movably to the arm under the influence of the driving wind, so that Windshield wipers on the windshield push them to one side or the other by the airflow. and can be blown between two positions through the air streams 65, whereby the tilting movement through mung should be moved back and forth. Each Schei-stops is limited, which the guide surface to the benwischer is here with an air flow exposed to the wind to offer a properly inclined surface, on which the corresponding, The guide surface can open inwards towards the
