Problems solved by technology

The expenditure on assembly time and assembly tools borne by the vehicle manufacturer is generally too high when fastening the wiper device by means of screw parts and damping elements
On the other hand, the screwless fastening mechanism disclosed in DE 198 33 404 A1 is not in all respects favorable for assembly due to its multi-part construction, and wherein the fastening mechanism also exists when it is used instead of a threaded part. Doubts in terms of mechanical reliability, which can only be overcome by an additional axial fixation of the plug pins in the receiving holes present in the rubber bushings

Embodiment Construction

[0020] FIG. 1 shows a glass-to-water device for motor vehicles known from the prior art, which comprises a rod-shaped support body 2 , which is supported at both ends by a bearing body 3 (shaped tube). A wiper shaft 4 for fastening a windshield wiper arm (not shown) is mounted axially fixed and rotatable in each bearing body 3 . Arranged on the support body 2 , approximately on its middle part, namely the plate 5 , is a drive 6 which acts on the connecting rod 7 . The end of the connecting rod 7 is hingedly connected to the swing arm 8 or 9, which is also rigidly connected to the wiper shaft 4 respectively.

[0021] This known windshield wiper device 1 is fastened at points 10 , 11 , 12 and 13 to a motor vehicle body 14 under a windshield (not shown) by means of fastening means. Currently, this fastening is typically achieved at least at one of the points 10 to 13 by means of a screw, while at other points plug pins can be provided on the device side. In other embodiments, t...

Abstract

The invention relates to a wiper installation (1) which is easy to install and can be fixed on the body without screws. For this purpose, both on the wiper installation and on the vehicle a respective plate-shaped area (15, 16) having a throughbore (17, 18) is provided. A clamp lock (20) comprises a tie bolt (21), insertable through the bores (17, 18), and a tension lever (22) which is rotatably received in its head portion (26). Said clamp lock (20) is made of a plastic material by multi-component injection molding as a one-part piece with a tension lever (22) rotatably disposed on the tie bolt (21).

Description

technical field [0001] The invention relates to a windshield wiper device for a motor vehicle, having a fastening mechanism with a plurality of fastening points on the device side, which are each designed to detachably interact with corresponding fastening points on the vehicle side , wherein at least one pair of fixing points cooperates without threaded connection. Background technique [0002] Such fastening of a wiper device to the body of a motor vehicle is known from DE 198 33 404 A1. The fastening at a given pair of fastening points takes place here as a screwless plug connection or snap-in connection, wherein on the device side there is provided a fastening means protruding from the support structure of the wiper device, which is designed to be plugged into the corresponding in the receiving hole formed on the side of the vehicle. The receiving opening itself is arranged in a special holder, for example a rubber sleeve, which is fastened to the vehicle body. [000...
