Embodiment Construction

[0014] A device for driving the windscreen wipers of a vehicle typically comprises a base 1 supporting two stationary arms 2 each of which supports at one end a bearing 3 of a rotating shaft 4 of the windscreen wiper . The shaft 4 is driven alternately in rotation by a crank 5 having two cranks, which itself is driven by a connecting rod 6 which is hinged on one side to the crank 5 and on the other side to a shaft 7 which is driven by The motor 8 supported by the base 1 is driven to reciprocate translation (forward and backward). The connecting rod 6 on the passenger side passes partially over the air inlet 10 of the vehicle ventilation and heating system.

[0015] If water flows along the connecting rod 6 on the passenger side, there is a risk of being sucked up by the air inlet 10 . When the driver activates the ventilation system, this water entry situation will cause the water to be carried into the heating pipes and then into the cabin, which is accompanied by atomizati...

Abstract

The invention concerns a device for driving motor vehicle windscreen wiper, of the type comprising at least two drive members consisting of a connecting rod (6) and a crank (5) driving the shaft (4) of a windscreen wiper blade, some parts of the connecting rod (6) and / or of the crank (5) passing above an air inlet scoop (10) of the vehicle ventilating and heating system. The invention is characterized in that it comprises a drop-breaker (12) arranged on the connecting rod (6) and / or the crank (5) at a location spaced apart overhanging said air inlet scoop (10).

Description

technical field [0001] The invention relates to a device for driving a windscreen wiper, comprising at least two drive members consisting of a connecting rod and a crank for driving a rotating shaft of the windscreen wiper. Background technique [0002] For the passenger, sometimes due to the tight space, a certain part of the connecting rod and / or the crank passes over the air intake of the ventilation and heating system. [0003] The Applicant has found that water sometimes enters the heating ducts, which presents a risk of water spraying into the vehicle compartment when the ventilation system is in operation. Contents of the invention [0004] The purpose of the present invention is to solve this problem. [0005] The present invention achieves its object by proposing to place the droplet smashing system on the connecting rod and / or crank at a location that does not overhang the air inlet. [0006] In particular, the present invention provides a device for driving a ...
