Definitions

• the invention relates to a windshield wiper with the features mentioned in the preamble of claim 1.
• Windshield wipers of the generic type are known. These are usually used to wipe windows of motor vehicles in order to ensure a clear view of a vehicle driver.
• the windshield wipers have a wiper arm which can be set into a swiveling or oscillating movement by means of a wiper drive.
• the wiper arm is connected at one end to a body-mounted wiper shaft, while the other, free end of the wiper arm carries a wiper blade.
• a holding bracket is provided which is detachably and articulated at the free end of the wiper arm.
• the detachable arrangement makes it possible to replace worn wiper blades, while the articulated arrangement allows the wiping movement to be adapted to curved windows. allowed.
• the wiper according to the invention with the features mentioned in claim 1 offers the advantage that the risk of breakage of the actuating means is reduced.
• Characterized in that the actuating means is assigned a stop to limit an actuating path it is advantageously achieved that on the one hand the unlocking of the latching connection is possible, but the load on the connection point between the actuating means and the intermediate piece is drastically reduced.
• the relative movement of the actuation Means of supply to the intermediate piece at the junction is limited to an elastic deformation, so that changes in the lattice structure occurring as a result of a deformation exceeding maximum elasticity - which could lead to a breakage - can be prevented.
• Figure 1 is a schematic overall view of a wiper
• Figure 2 is an exploded perspective view of a connection point between a wiper arm and a bracket and
• Figure 3 is a perspective view of an intermediate part in a sectional view.
• FIG. 1 shows a wiper 10.
• the wiper 10 has a wiper arm 12, one of which End 14 turn test is arranged on a wiper shaft 16.
• the other, free end 18 of the wiper arm 12 carries a wiper blade 20.
• the wiper blade 20 is held by a holding bracket 22, which can be detachably and articulately connected to the end 18 of the wiper arm 12 via a fastening part 24.
• the articulated connection takes place via an axis of rotation 26 which extends approximately perpendicular to the wiper axis 16.
• FIG. 2 shows an exploded view of the connection area between the fastening part 24 of the holding bracket 22 and the end 18 of the wiper arm 12.
• the attachment takes place via an intermediate piece 28.
• the intermediate piece 28 is a molded part, which on the one hand can be connected to the wiper arm 12 in a positive and non-positive manner and on the other hand enables the wiper arm 20 and the wiper arm 12 to be arranged in an articulated manner.
• the intermediate piece 28 consists of two side parts 30 and 32 arranged essentially parallel to one another, which are connected to one another via webs 34 and 36 and a hollow body 38.
• the hollow body 38 forms an opening 40 which is open at the edge and serves to receive the axis of rotation 26 of the holding bracket 22.
• the side parts 30 and 32 have funnel-shaped cutouts 42 which open into a slot 44 in the passage opening 40.
• a width of the slit "44 is selected to be smaller than the diameter of the rotation axis 26 so that the intermediate piece 28 can be snapped onto the axis of rotation 26th
• the diameter of the through opening 40 is based on the diameter
• the axis of rotation 26 is coordinated such that the intermediate piece 28 can be rotated around the axis of rotation 26 without play.
• a receptacle 46 for the end 18 of the wiper arm 12 is formed between the side parts 30 and 32.
• the hollow body 38 forms a contact surface 48 against which a hook 50 of the end 18 with its inner lateral surface 52 bears in a form-fitting manner.
• the hook 50 is virtually guided over the hollow body 38, so that it is arranged in a free space 54 of the hook 50.
• the side surfaces 30 and 32 which protrude beyond the hollow body 38, bear against end surfaces 56 of the wiper arm 12.
• the side parts 30 and 32 have inwardly directed nub-like elevations 58, between which the wiper arm 12 is quasi clamped with its end faces 56.
• a spring tongue 60 arises from the hollow body 38 and is pressed against the hollow body 38 by the hook 50, so that a play-free holding is also possible in the axial direction of the wiper arm 12.
• a tab 62 arises from the hollow body 38 and serves as an actuating means 64 for locking the connection between the holding bracket 22 and the wiper arm 12 via the intermediate piece 28.
• actuating means 64 By means of the actuating means 64, a locking web 66 can be locked in a groove 6 ' 8 of the wiper arm 12.
• the actuating means 64 is shown here in a locking position A and an unlocking position E.
• the tab 62 extends from a wall 70 of the hollow body 38 and is hinged there in accordance with a thickness of the tab 62.
• a connecting area 72 between the wall 70 and the tab 62 forms a pivot axis 74 of the actuating means 64.
• the locking web 66 engages in the groove 68 of the hook 50 so that it is secured against a relative displacement to the intermediate piece 28.
• Unlocking takes place by pivoting the actuating means 64 about the pivot axis 74, so that the locking web 66 disengages from the groove 68.
• the wiper arm 12 can be detached from the intermediate piece 28. This is necessary, for example, to replace a wiper blade 20, for example due to wear.
• a further web 76 arises from the side part 32.
• the web 76 forms a stop 78 for the actuating means 64.
• the web 76 is arranged in such a way that when the actuating means 64 is struck, the locking web 66 reached with the groove 68. By limiting the actuation path, material fatigue in the area of the connection point 72 between the hollow body 38 and the tab 62 is prevented, so that, for example when the actuating means 64 is actuated several times, a fatigue fracture can be prevented at this point.
• the web 76 has a bevel 80 on its surface facing the tab 64, which forms a stop surface 82 of the stop 78. This ensures that the tab 62 is not guided against a sharp-edged stop 78 when it is transferred to the unlocking position E. A flat introduction of a holding force opposite to the direction of movement of the tab 62 thus takes place through the flat stop 78, so that, viewed over the length of the tab 62, it is not subjected to high bending stress around the stop 78.
