Abstract
A gel is used as the joining agent to mount a rain sensor to a windscreen of an automobile. The gel used does not harden even in the long term, and air pockets which form inside the gel or on the boundary surfaces with the glass pane or the sensor migrate into the area around the sensor. The rain sensor is attached to a glass pane without special elastic intermediate elements, using the elasticity of the joining agent for tolerance compensation.
Claims20
A device for mounting a rain sensor on a body comprising:
- a silicone gel permeable to infrared light joining the rain sensor to the body;
- the rain sensor rigidly embedded in a sensor housing;
- an edge of the sensor housing resting on the body having local projections;
- and
- a holder supporting the sensor housing on the body, the holder including:
- a wall protruding from the body, the wall accommodating a portion of the sensor housing;
- and
- a cover enclosing the sensor within the sensor housing, the cover having locking tabs connectable to respective recesses in the wall and having at least one of a radially-extending projection and a radially-extending recess such that, in a closed position, the at least one of the radially-extending projection and the radially-extending recess of the cover respectively engages one of a radially-extending recess and a radially-extending projection of the housing.
A device for mounting a rain sensor to a windshield of a vehicle, comprising:
- a silicone gel joining a portion of a facing surface of the rain sensor to the windshield;
- a sensor housing surrounding at least an outer peripheral edge of the rain sensor;
- projections extending from a surface of the sensor housing facing the windshield, the projections in contact with the windshield;
- and
- a holder engaged about an outer peripheral edge of the sensor housing, the holder including:
- a sealing strip extending along an inside edge of the holder, the sealing strip in contact with the windshield and spaced from the outer peripheral edge of the sensor housing;
- an adhesive surface extending away from the sealing strip, the adhesive surface opposed to and spaced from the windshield;
- and
- an inner surface extending from the sealing strip and away from the windshield to contact the sensor housing.
A device for mounting a rain sensor to a windshield of a vehicle, comprising:
- a silicone gel joining a portion of a facing surface of the rain sensor to the windshield;
- a housing extending between the windshield and the rain sensor for a remainder of the facing surface of the rain sensor and extending from a surface of the windshield to enclose an outside peripheral edge of the sensor;
- and
- projections extending from a surface of the housing facing the windshield, the projections in contact with the windshield.
A device for mounting a rain sensor that operates with radiation on a body with the rain sensor being joined to the body with silicone gel comprising:
- silicone gel being colored with a dye that is permeable to infrared light;
- the rain sensor being rigidly embedded in a sensor housing;
- an edge of the sensor housing which rests on the body being provided with local projections;
- and
- a holder mounted on the body, with the holder engaging on the sensor by one of directly and by an essentially rigid intermediate element and the holder indirectly pressing the sensor against the body via the silicone gel, wherein the holder is realized integrally with the body.
