  • the disk 1 is essentially planar over a larger part of its disk surface, but at the edge, i.e. at the edge. H. when the pane 1 is designed as a vehicle front pane in the area of the so-called A-pillar 2 of the vehicle, it is convexly curved on the outer surface, in such a way that this curvature increases with a decreasing distance from the A-pillar 2, as is particularly the case in FIGS 3 can be seen.
  • FIGS. 1-3 also show a wiper arm arrangement 3 which, in the manner described in more detail below, consists of at least one wiper arm 4 and an auxiliary or control arm 5.
  • the wiper arm 4 is provided in the usual way on the other end of the vehicle, not shown in FIGS. 1-3, on a wiper shaft 4.1 driven for the wiping or pivoting movement, and the control arm 5 at this end of the wiper arm arrangement about an axis parallel to the axis the wiper shaft, but is articulated radially offset from the wiper shaft axis on a vehicle-side bearing 5.1 (FIG. 4).
  • the wiper blade 6 is fastened, which is indicated schematically in FIGS. 1-3 by its wiper rubber, specifically with the wiper lip 6.1 resting on the window 1.
  • the wiper blade 6 or the wiper lip 6.1 are each oriented as perpendicularly as possible to the outer surface of the pane 1, as is shown with the normal position N in FIGS. 1-3.
  • a wiper blade holder 7, on which the wiper blade 6 is interchangeably provided in the usual manner can be pivoted in a bearing 8 about an axis which runs parallel or approximately to the longitudinal axis of the wiper blade 6 and, in the embodiment shown, also in The longitudinal direction of the wiper arm 4 extends, specifically controlled by the control arm 5, which is provided on the side of the wiper arm 4.
  • the control arm 5 is guided at its end on the wiper blade on the wiper arm 4, specifically in the embodiments shown in the figures by means of an articulated lever 9 which is connected at one end to the control arm 5 via a joint 10 and at the other end via a joint 11 at one end of a Boom 12 is articulated, which is attached with its other end to the wiper blade end of the wiper arm 4 and protrudes radially from this end.
  • the axes of the two joints 10 and 11 are parallel to one another and also parallel or approximately parallel to the axis of the wiper shaft 4.1 and the joint 5.1.
  • the wiper blade-side end of the control arm 5 is also connected via a control lever 13 to the end of a pivot arm 14 projecting radially from the pivot axis of the wiper blade holder 7, specifically via ball joints 15 and 16, of which the ball joint 15 is formed by a ball head of a joint pin which at the same time forms the joint 10.
  • the two levers 10 and 13 are located on the side of this arm 12 facing away from the vehicle window 1.
  • FIGS. 4 to 6 show, as a possible embodiment, a wiper arm arrangement 3 a, which differs from the basic design described above essentially in that the wiper blade holder 7 can additionally be pivoted over a limited angular amount about an axis that is perpendicular to the pivot axis of the joint 8 and is oriented perpendicular to the surface of the vehicle window 1 when the wiper arm arrangement 3a is mounted on the vehicle.
  • the wiper blade 6, which is only indicated by a broken line in FIG. 4, is as close as possible in the parking position and parallel to the lower edge and in the reverse position is as parallel as possible to the edge adjacent to the A-pillar 2 the vehicle window 1 lies.
  • the swivel arm 14 is at one end of a shaft 17 and projects radially away from it.
  • the shaft 17 forms, together with a bearing 18 on the wiper blade end of the wiper arm 4, the joint 8 for adapting the normal position of the wiper blade 6.
  • a further bearing element 19 is fastened, which is also pivoted when the shaft 17 is pivoted and radially offset to the axis 17.1 of the shaft 17, on the Control arm 5 facing away from this axis 17.1 has a joint 20 with which the wiper blade holder 7a corresponding to the wiper blade holder 7 can be pivoted about the pivot axis 20.1 oriented perpendicular to the axis 17.1 for the additional pivoting movement.
  • the wiper blade holder 7a forms a lever or swivel arm 7a.1 projecting radially from the joint 20 in the direction of the vehicle-side end of the wiper arm arrangement 3a, which at its free end via a joint 21 e.g. Ball joint is connected to one end of a further control arm 22, which is articulated at its end on the vehicle side via a joint 23 to a bearing 24 which does not pivot with the wiper shaft 4.1, namely about an axis parallel to the axis of the wiper shaft 4.1, but radially with respect to the latter added.
  • a joint 21 e.g. Ball joint
  • Ball joint is connected to one end of a further control arm 22, which is articulated at its end on the vehicle side via a joint 23 to a bearing 24 which does not pivot with the wiper shaft 4.1, namely about an axis parallel to the axis of the wiper shaft 4.1, but radially with respect to the latter added.
  • FIGS. 7-9 show, as a further possible embodiment, a wiper arm arrangement 3b which differs from the wiper arm arrangement 3a essentially in that the control arm 22 is dispensed with and its function is also taken over by the control arm 5.
  • a lever 26 is articulated on the end of the shaft 17 having the swivel arm 14 via a joint 25, for example a ball joint, the other end of which is connected via a joint 27, for example a ball joint, to the free end of the swivel arm 7b.1 formed by the wiper blade holder 7b connected is.
  • FIGS. 10 and 11 show, as a further possible embodiment, a wiper arm arrangement 3c, which differs from the wiper arm arrangement 3b in that, instead of the lever 26, a lever 28 is provided which is axially displaceable on the wiper arm 4 by means of a joint 29 between its two ends and is pivotally mounted, in the embodiment shown, about an axis perpendicular to the axis 17.1 of the shaft 17 and parallel to the axis of the wiper shaft 4.1.
  • the shorter lever arm of the double-armed lever 28 is drivingly connected to a driver 30 which projects radially away from the shaft 7.
  • the free end of the pivot arm 7c.1 is articulated with a joint 31, which functionally corresponds to the pivot arm 7b.1 and is part of the wiper blade holder 7c corresponding to the wiper blade holder 7b.
  • the function of the control arm 22 is taken over by the control arm 5, i. H. Via this control arm, both the pivoting of the wiper blade 6 about the axis 17.1 to adjust the normal position and the pivoting about the axis 20.1 for orienting the wiper blade 6 in the reverse position in parallel or as far as possible parallel to the A-pillar 2 is achieved.
  • FIGS. 12 and 13 show, as a further possible embodiment, a wiper arm arrangement 3d, which differs from the wiper arm arrangement 3b essentially in that the pivoting of the wiper blade holder 7d about the axis 20.1 of the joint 20 takes place via a lever or swivel arm 32 which is connected to a End is attached to the shaft of the joint 20 and which is articulated at its other end via a lever serving as a coupling to the wiper blade end of the control arm 5.
  • the wiper blade holder 7d is also connected to the shaft of the joint 20, so that when the control arm 5 moves relative to one another the pivoting of the wiper blade holder 7b about the axis 20.1 of the joint 20 takes place.
  • the joints 34 and 35 are designed such that pivoting of the bearing element 19 about the axis 17.1 is possible. With the wiper arm arrangement 3d there is also the possibility of providing the joint 35 coaxially with the joint 10.
  • the wiper arm arrangements 3a - 3d also have in common that, in addition to this pivoting for the adjustment of the normal position of the wiper blade 6, the pivoting of the wiper blade 6 about the axis of the joint 20, i. H. around the axis perpendicular to the longitudinal extension or approximately perpendicular to the longitudinal extension of the wiper blade 6, specifically to adapt the position of the wiper blade in the reversed position to the course of the edge of the disc 1 in the region of the A-pillar 2. While in the wiper arm arrangement 3a this pivoting is controlled by the additional control arm 22, the other embodiments have in common that the control of the wiper blade 6 to adapt the position of the wiper blade 6 in the reversed position to the course of the edge of the disc 1 is carried out by the control arm 5.
  • the wiper arm arrangements 3b and 3c have in common that the pivoting of the wiper blade holder 7b or 7c takes place by pivoting the shaft 17, while in the wiper arm arrangement 3d the pivot arm 32 oriented with its longitudinal extension transverse to the relative movement of the control arm 5 via the coupling or the lever 33 attacks directly on the control lever 5.
