Problems solved by technology

The disadvantage of this type of device is the need for parts that tighten the cable in order to ensure that the drive of the cable by the pulley it rests on is always of good quality
[0007] Such devices are still complex and bulky, especially when they should accommodate glass with a certain raised profile

Embodiment Construction

[0024] figure 1 The rear part of the motor vehicle shown is, for example, the tailgate (hayon) indicated as a whole by 1 , the outer shell of which has been removed and which includes the rear window 2 . Located in the tailgate is a glass wiping device, generally indicated at 10 , comprising a linearly movable glass wiping brush 11 , known per se, carried by a carriage 12 extending along the upper edge 3 of the rear window 2 Slide in the guide rail 13. The carriage 12 is driven by a drive part generally indicated by 14 which drives a transmission part 15 connected to the carriage 12 . It can be noted that the transmission part 15 extends in particular between the outlet 21 of the drive part 14 and the end 22 of the guide rail 13 . As will be seen below, the transmission member 15 comprises parts sliding inside guide grooves provided in the guide rail 13 .

[0025] as in image 3 As seen in , the transmission part represented by 15 as a whole is a flexible rack made of a ca...

Abstract

The inventive windscreen wiper device (2) comprises a windscreen wiper (11), which is linearly displaceable and is carried by a carrier (12) which is guided by a guiding rail (13) connected to a transmission means (15) driven by an actuating means (14). Said invention is characterised in that said guiding rail (13) is provided with at least one longitudinal chute for maintaining the transmission means (15) element and said transmission means is selected such that it is flexible and comprises an element slidable in said longitudinal chute of the guiding rail (13).

Description

technical field [0001] The invention relates to a glass wiping device comprising a linearly movable glass wiping brush. Such a device can be used in particular for wiping motor vehicle windows, in particular motor vehicle rear windows. Background technique [0002] A glass wiping device for motor vehicles is known, said device comprising a linearly movable glass wiping brush carried by a carriage guided by guide rails and driven by a transmission part connected to the drive part. [0003] In particular it is known that the carriage carrying the glass-scraping brush is driven by an apparently straight worm, which requires special means to keep the glass-scraping brush against the glass at all times, especially when the glass has a certain bulge When contouring. [0004] These devices with worms are also available with single-threaded worms and with double-threaded worms. The advantage of double-threaded worms is that these worms can be driven by a motor that turns in one d...
