Description

(1) An exemplary embodiment of the invention will be described below, with reference to one FIGURE. In the drawing:

(2) FIG. 1 shows a perspective view of a testing device for determining a contact pressure of a vehicle side window on a window seal.

(3) FIG. 1 shows a perspective view of a testing device 1 that is used to determine the contact pressure of a vehicle side window (not shown here) on a window seal (also not shown). In order to determine the contact pressure, the testing device 1 comprises a central processing unit 2, which is connected to a pressure measuring film of the testing device 1 via an evaluation unit (not shown here) integrated in the central processing unit 2 via a cable integrated in a connection piece 4.

(4) The connection piece 4 connects the evaluation unit to the pressure measuring film comprising a plurality of pressure measuring sensors (not shown here), which film is connected to a positioning element designed as a bracket 5 in the exemplary embodiment shown. The bracket 5 makes it possible to arrange the pressure measuring film such that said film engages around the edge of the vehicle window, and therefore the pressure measuring film contacts portions of a window inner face, of the window outer face and of an end face of the vehicle side window 1. Suction cups 6 arranged opposite one another on the inside of the bracket 5 make it possible to precisely align and secure the pressure measuring film on the vehicle side window.

(5) In the closed state of the vehicle side window, the pressure measuring film is loaded on all sides by the window seal. The contact pressure of the vehicle side window on the window seal can therefore be determined on all sides by means of pressure measuring sensors arranged so as to be distributed over the surface of the pressure measuring film.

(6) The data obtained are evaluated via the evaluation unit of the central processing unit 2, which outputs the determined results via an LED display of a display unit 3 of the central processing unit 2.

(7) The pressure measurement results may be output to the user in the form of exact values. Alternatively, it is possible to signal to the user that the determined contact pressures are correct or that they deviate from predetermined values by simply displaying “OK” or “Not OK”. The central processing unit 2 optionally comprises a memory unit, in which the predetermined contact pressures for the relevant vehicle type are stored, such that comparison with the measurement data obtained is possible using the evaluation unit. The central processing unit 2 may also be designed for connection, in particular wireless connection, to an external memory unit.
