Abstract
A windshield wiper assembly in addition to carrying the wiper blade, also carries an additional cleaning device which may be a brush, an ice scraper, or an additional blade through which washer fluid may be sprayed. The additional device is coupled with the wiper arm-and-blade assembly by means of a coupling which may be operated by an adjusting element. The additional part is only used, when it is really necessary and, in addition, serves to reduce pressure on the wiper arm-and-blade assembly in the parking position.
Claims34
A vehicular window cleaning apparatus, comprising:
- a windshield wiper assembly including a wiper arm-and-blade and drive means for driving said wiper arm-and-blade;
- an additional part for intensifying the cleaning effect of said wiper blade;
- a coupling for coupling said additional part to said assembly for movement with said wiper arm-and-blade;
- and
- an adjusting element for operating said coupling to selectively couple said additional part to said assembly and uncouple said additional part therefrom.
A vehicular window cleaning apparatus, comprising:
- a windshield wiper assembly including a wiper arm-and-blade;
- an additional part for intensifying the cleaning effect of said wiper blade;
- a coupling for coupling said additional part to said assembly, said coupling comprising a spring loaded structural unit which acts upon at least one of said wiper arm-and-blade assembly and said additional part;
- an adjusting element for operating said coupling to selectively couple and uncouple said additional part to said assembly;
- an actuator operable by said adjusting element;
- the spring force of said spring loaded structural unit being only so great, that it can be overcome with the release of the coupling action by a change in the position of said actuator;
- an axle mounted on said additional part and extending in the longitudinal direction of said wiper arm-and-blade assembly;
- said structural unit comprising a two-armed catch rotatable about said axle and a spring supporting a first arm of said catch on said additional part, said first arm having a hooked end and adapted to lockingly engage said wiper arm-and-blade assembly;
- and
- a tappet displaceable by said adjusting element, the second arm of said catch being movable by said tappet in a direction opposite to the direction of force of said spring.
A cleaning apparatus in accordance with claim 37, wherein:
- said wiper blade is articulated lateral to said wiper arm.
