Definitions

• the invention relates to a windshield wiper device, in particular for a motor vehicle, with a fastening part for fastening a wiper arm on a wiper shaft.
• the object of the invention is to improve a windshield wiper device of the type mentioned at the outset in such a way that manufacturing tolerances in the area of the wiper arm can be compensated for in the future.
• the invention solves this problem by a windshield wiper device of the type mentioned, in which, according to the invention, the position of the wiper arm can be adjusted transversely to the wiper shaft with the fastening part.
• manufacturing tolerances can be eliminated in the future when installing the wiper arm. be compared.
• This compensation option avoids the undesirable narrow points and collisions between the wiper arm and the body or the window.
• design requirements can be met precisely with the windshield wiper device according to the invention.
• the fastening part can have a lower part and an upper part which can be displaced relative thereto.
• the windshield wiper device according to the invention can be implemented in a structurally very simple and thus also inexpensive manner.
• the lower part can expediently sit on the wiper shaft, whereas the wiper arm is attached to the upper part.
• the upper part and the lower part can be displaced relative to one another along the grooves, as a result of which the position of the wiper arm can be continuously adjusted transversely to the wiper shaft.
• the grooves enable a positive connection for torque transmission between the lower part and the upper part, the torque being transmitted transversely to the grooves.
• the upper part can have a recess for receiving the lower part. Then the lower part can be at least partially sunk in the upper part.
• this constructive measure saves installation space and, on the other, creates a further positive connection between the lower part and the upper part. Due to the positive connection, outer surfaces of the lower part are in contact with inner surfaces of the upper part, so that a torque transmission is likewise transmitted through the outer surfaces of the lower part and the inner surfaces of the upper part. can occur if the positive locking of the grooves is not sufficient.
• the upper part can advantageously have an elongated hole for pushing through the wiper shaft.
• the elongated hole enables the upper part receiving the wiper arm to be positioned transversely to the wiper shaft. Because the wiper shaft can be inserted through the upper part, the upper part and the wiper shaft can be screwed together, for example by a nut.
• the lower part can have a hole for inserting the wiper shaft.
• the hole in the lower part can also be conical.
• the upper part can have a further recess for receiving a nut or a screw head.
• the recess allows the nut or the screw head to be countersunk in the upper part, which saves installation space.
• Figure 1 is an exploded perspective view of the fastening part and the wiper shaft. 2a shows a perspective view from above of the upper part;
• 3a shows a perspective view from above of the lower part
• 3b shows a perspective view from below of the lower part
• Fig. 4 is a sectional view through an assembled fastener
• FIG. 5a shows a perspective view from below of the mounted fastening part in a first position
• 5b shows a perspective view from below of the mounted fastening part in a second position
• Fig. 5c is a perspective view from below of the assembled fastener in a third position.
• FIG. 1 shows a fastening part 10 which has a lower part 11 and an upper part 12.
• the lower part 11 and the upper part 12 abut one another and can be plugged onto a wiper shaft 13.
• the wiper shaft 13 has an external thread de provided, on which a nut 14 is screwed for fastening the fastening part 10.
• the upper part 12 has a recess 20 on its upper side (see FIG. 2a), in which the nut 14 is at least partially countersunk.
• the upper part 12 On its underside, the upper part 12 is provided with grooves 21 (see FIG. 2b) which engage in grooves 30 in the lower part 11 (see FIG. 3a) (see FIG. 4).
• the upper part 12 can be moved relative to the lower part 11 along the grooves 21 and 30, whereby the position of a wiper arm, not shown here, can be continuously adjusted transversely to the wiper shaft 13.
• the grooves 21 and 30 also ensure a positive connection for torque transmission between the lower part 11 and the upper part 12. The torque transmission takes place transversely to the grooves (FIG. 4).
• the upper part 12 is also provided on its underside with a recess 22 for receiving the lower part 11. Consequently, the lower part 11 can be at least partially sunk in the upper part 12.
• the recess 22 forms a further positive connection of the lower part 11 with the upper part 12.
• the positive connection means that outer surfaces 31 of the lower part 11 are in contact with inner surfaces 23 of the upper part 12 (see FIGS. 2b, 3a, 3b and 4). As a result, torque transmission can also take place through the outer surfaces 31 and the inner surfaces 23 if the positive locking of the grooves 21 and 30 is not sufficient to transmit the torque (FIG. 4).
• the upper part 12 is provided with an elongated hole 24 through which the wiper shaft 13 is inserted. The elongated hole 24 enables the upper part 12 to be positioned transversely to the wiper shaft 13.
• the lower part 11 has a hole 32 through which the wiper shaft 13 can be inserted.
• the wiper shaft 13 has a conical region 15 to which the hole 32 of the lower part 11 is adapted (see FIGS. 1 and 4).
• the figures 5a, 5b and 5c show the fastening part 10 mounted on the wiper shaft 13 in different positions.
• the fastening part 10 is located with its center on the wiper shaft 13.
• the fastening part 10 is mounted in the two outermost positions on the wiper shaft 13.
