A retaining frame for a support element of a sensor in a motor vehicle is disclosed. The retaining frame has a flat underside that can be adhered to a window of a motor vehicle, and having an opening with at least one contact surface for the support element in which opening the support element can be positioned flat on the window and against the contact surface, and has a spring element by which a force can be applied to the support element.

As is well known, the influencing variables most important for a sense of comfort are considered during regulation in controlled heating and air conditioning units. Incipient condensation on the windshield or other windows in particular is to be prevented thereby. Sensor modules, inter alia, are employed for this purpose, which have, for example, a capacitative thin-layer sensor. An additional thermopile is provided for determining the window temperature. The present idea eliminates the determination of the window temperature, for which purpose a sensor working capacitatively in the exemplary embodiment is brought directly to the window temperature and a direct thermal coupling of the sensor with the window occurs via a metal plate connected directly to the sensor and a thin adhesive film. The metal plate can thereby form one of the electrodes of the sensor itself or be connected to said electrode in a direct thermal manner. The use of the sensor in the sensor module is a further preferred embodiment.

An adjustable assembly comprises a base (mount ring 1), an adjustable part (inner ring 3), a lever (tilting lever 5) and a drive (drive element 6). The lever (tilting lever 5) is connected to the base (mount ring 1) and to the adjustable part (inner ring 3) via two elastic solid pivoting joints (7, 8) oriented in parallel. One of the two solid pivoting joints (7) is divided into two pivoting joint parts (7a, 7b), which are arranged such that along their pivoting axis (9) they are offset sideways on either side of the second solid pivoting joint (8).

The regulated heating and air conditioning installations normally enable, when controlled, integration of the main factors affecting the comfort of passengers, in particular preventing the windscreen and the other windows from getting clouded. In order to detect incipient mist formation, condensation and moisture sensors generate detection signals, which initiate steps for preventing mist formation when a threshold value is exceeded. Measures are taken for preventing mist formation based on requirements and in a manner adapted to the changing moisture conditions of the glass panes, for example, by using points of intervention stored in a processor. Steps are therefore taken to prevent mist formation, based on moisture variation gradients of the glass panes. Depending on the moisture of the glass panes varying in time and in terms of values, each point of intervention is generally set on as soon as possible, but the latest possible, the local conditions and local meteorological elements being taken into consideration when the method is applied.
摘要:
The invention relates to a sensor unit for detecting the wetting of a window. Signals from the condensation sensor are used to control an air conditioning, heating, and/or ventilation unit. The signals of the rain sensor, on the contrary, are used to control a windshield wiper or washing unit for vehicles. A sensor unit, which comprises two sensors, is placed on the interior of the window. In a preferred variant, both are coupled to a common switchable evaluation unit, so that through mutual evaluation of the two sensors or their signals, both incipient condensation on the interior of a vehicle window and the wetting of the exterior, e.g., by rain, is detected. In an improvement of the invention, both sensors are integrated into a sensor module.
