Problems solved by technology

[0009] [09] However, after the bearing is eliminated, the scraper arm and the brushes also extend outside the motor vehicle, thereby restricting the elimination of the bearing, which itself constitutes a wounding object that can cause injury

Embodiment Construction

[0024] [24] In order to describe the invention, as a non-limiting example, the vertical, longitudinal and transverse orientations indicated by the symbols V, L, T in the drawings are taken.

[0025] [25] also adopted the back-to-front direction as the longitudinal direction, and the left-to-right direction as shown in Fig. 1 .

[0026] [26] In the following description, the same, similar or similar components are denoted by the same reference numerals.

[0027] [27] FIG. 1 shows a motor vehicle window wiper 10 , with a drive shaft 14 having a bearing 12 and a wiper arm 16 .

[0028] [28] The bearing 12 guides and fixes the rotation of the transmission shaft 14 . It is provided with a tubular strut 18 having a vertical axis A for receiving a transmission shaft 14 rotating about its axis A.

[0029] [29] For its fastening to the motor vehicle body structure 20 , the bearing 12 has a generally annular seat 22 coaxial with the strut 18 .

[0030] [30] According to a known desig...

Abstract

The invention concerns an arrangement for fixing a wiper device (10), comprising: a stem (18) for guiding in rotation and fixing a shaft (14) driving a wiper arm (16) and which is fixed on a body structure element (20) of the vehicle by means (24,30) enabling its disengagement from the body structure element (20) upon impact; and a driving head (14) which links the wiper arm (16) to the driving shaft (14) and which comprises a front element (34) bearing the wiper arm (16), and a rear element (36) mutually linked by means (50) enabling the wiper arm (16) to be disengaged from the body structure element (20). The invention is characterized in that the means linking the front element with the rear element comprise at least one intermediate part (50) which is adapted to be disengaged from the front element (34), or from the rear element (36) upon disengagement of the stem (18) from the body structure element (20).

Description

technical field [0001] [01] The invention relates to a device for securing a motor vehicle wiper. [0002] [02] The invention relates in particular to a device for securing a motor vehicle wiper, which device has: [0003] [03]- The wiper arm alternately sweeps the rotary guide and fixed bearing of the transmission shaft, extending axially substantially in the vertical direction, fixed on the motor by means of at least partially detaching from the body structure when the wiper is subjected to an impact on vehicle body structures; and [0004] [04]-Drive head, connecting the scraper arm to the drive shaft, having a front member supporting the scraper arm and a complementary chamber at least partially received in the front member by a sleeve coaxial with the drive shaft The rear member in the said front member and the rear member are connected to each other by means of separating the wiper arm from the drive shaft when the bearing is separated from the body structure.
