Description

8. Headlight washer system according to An It is the object of the invention to provide a headlight claim 1 to 7, characterized in that via fer-wiper washer system for vehicles, in particular the wiper and / or washer switch (WiSo, 55 for motor vehicles, to control that an uncontrolled WaSo) the windshield wiper washer a controllable operation is avoided.

All operation with the windshield wiper washer switch WaSl and the wiper switch can be operated, but that it does not necessarily control WiS 1. As long as the wiper washer must be operated with it. At the wiper switch WWSo of the windshield wiper wash system you can see which one is switched on, the actuation of the wiper drive status of the headlight wiper wash switch WWS 1 of the headlight wiper wash system prevails if the associated wiper washer system does not Impact. Only when the wiper switch is operated. With this dependency, the switch switch WiSo of the windscreen wiper system is in the position of the wiper washer switch in the headlight switch position I or II. If the control potential WischwaschaiJage it is sufficient if the wiper of the connection 15 switch via the switch output 53 b and the washer switch of the headlights and the diode D1 or via the switch output 53 fer-wiper washer system via a common actuator and the diode D 2 on the connection 53 a of the Wigungsorgan can be switched on and off at the same time. switch WiS 1. If the Wi-So that this parallel operation of the two wiper washer switches WiS 1 is actuated, then the system is limited to a minimum, and then the wiper motor M1 of the headlights can also be provided so that this wiper system is switched on. When switching off the wiper switch as a self-resetting push button switch switch WiS 1, the headlight wiper is formed. position via the reset switch RS 1 in the parking

The control of the headlight wiper washer Jung brought, with the reset switch RS 1 position is designed according to an embodiment of the invention so and the break contact of the wiper switch WiS 1 that over the wiper switch of the headlight 20 short circuit to the ground terminal 31 for the projector wiper system and a reset switch that closes the wiper motor Af 1,
Via a switch cam of the wiper motor in itself The operated washer switch WaS 1 of the bill known way is in the park position, the launcher washing system prepares a circuit for the wiper motor of the headlight wiper system controls a washing pump P 1 or a solenoid valve that can be detected. A headlight washer can be installed using the washer switch. This washing pump circuit or a headlamp solenoid valve only becomes effective when the WaSofer washing system washer switch is activated. the windscreen washer is closed. Included

If the wiper switch of the windscreen wiper switch then also the washing pump Po of the windshield layer has several operating positions, provision is made for the washing system to be switched on. Since the washer switch, that is, the wiper switch of the headlight wiper of the windscreen washer system is designed as a self-resetting washing system via decoupling diodes with the switching switch, both different switching positions or switching outputs of the washing systems are switched off at the same time. The Wades wiper switch of the windshield wiper system switch WaS 1 of the headlamp washer system is bundled and so in each switched-on position it only decides whether or not the windshield wiper position can be controlled at the same time. 35 the headlight washer system must be switched on.

Since the Scheir.werfer wiper washer system is only of use when the wiper motor Mo of the windshield wiper system is illuminated, it is provided via the reset switch RSo and the Witerhin that the control circuit wiper switch WiSo of the combined wiper wheel wiper and / or washer switch the ticket switch WWSo controlled.

A link with the control circuits tet. This relay R closes via its contact c of the wiper washer switch with contacts of the control circuit for the wiper switch light switch is possible if the headlight wiper system is via the 45 WiS 1. This wiper and / or washer switch of the window control circuit leads a switching relay on and off via contact 58 of the wiper and washer system - light switch LS to control potential +30. Which can be switched. the control windshield wiper system via its contact must be in operation and the circuit for the wiper and / or washer switch LS must be switched on when the lights of the headlight wiper system closes. 50 turret wiper system via the wiper switch WiS 1
