Abstract
Vorrichtung zum Verhindern des Einklemmens eines Gegenstands zwischen dem Rahmen und der Scheibe eines von einem Motor zu öffnenden und zu schließenden Fensters, insbesondere Kraftfahrzeugfensters, mittels eines in den von dem Rahmen umfaßten Raum gerichteten, den Motor steuernden Sensors, dadurch gekennzeichnet, daß der Sensor als ein auf Wärmestrahlung von Warmblütern ansprechender pyroelektrischer Sensor ausgebildet ist.Device for preventing an object from getting jammed between the frame and the pane of a window that can be opened and closed by a motor, in particular a motor vehicle window, by means of a sensor which controls the motor and is directed into the space enclosed by the frame, characterized in that the sensor as a pyroelectric sensor responding to thermal radiation from warm-blooded animals is formed.
Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.
Eine bekannte Vorrichtung dieser Art weist ein elastisches Hohlprofil mit Rahmen und eine sich durch das Hohlprofil erstreckende Lichtschranke auf. Bei Einklemmen eines Gegenstands wird das elastische Hohlprofil zusammengedrückt und daraufhin die Lichtschranke unterbrochen. Hierdurch wird ein Steuersignal ausgelöst, das den Lauf des Motors umkehrt. Nachteilig ist dabei, daß der Sensor erst dann anspricht, wenn ein Gegenstand mit einer vorgegebenen Kraft eingeklemmt ist. Durch entsprechende Wahl dieser Kraft lassen sich zwar Verletzungen vermeiden. Handelt es sich bei dem eingeklemmten Gegenstand um den Finger einer Person, so wird jedoch diese Person zumeist in Schrecken versetzt, sei es, weil sie nicht weiß, daß ein Klemmschutz besteht oder sei es, daß sie der Funktion des Klemmschutzes nicht voll vertraut.A known device of this type has an elastic Hollow profile with frame and a light barrier extending through the hollow profile. When jammed of an object, the elastic hollow profile is compressed and then the light barrier interrupted. This triggers a control signal that reverses the motor. Disadvantageous is that the sensor only responds when an object is jammed with a predetermined force is. By choosing this force accordingly, injuries can be avoided. Is it in the case of the object trapped around a person's finger, however, that person is mostly in Terrified, be it because they do not know that there is protection against trapping or that it is functioning of the trap protection is not fully trusted.
Nach der US-PS 26 65 129 ist es bekannt, als Sensor ein auf Wärmestrahlung von Warmblütern ansprechendes Pyrometer in der Nähe einer Tür anzubringen, um mit seiner Hilfe die Tür selbsttätig zu öffnen, wenn sieh eine Person der Tür nähert.According to US-PS 26 65 129 it is known as a sensor place a pyrometer sensitive to thermal radiation from warm-blooded animals near a door in order to with its help to open the door automatically when a person approaches the door.
Aulgabe der Erfindung ist es. eine Vorrichtung mich dem Oberbegriff des Anspruchs 1 anzugeben, die in dem Fenster ohne große Raumbeanspruchung dem Rahmen des Fensters angepaßt anzubringen ist, bereits dann anspricht, wenn ein Gegenstand mit der Temperatur eines Warmblüters, also etwa ein menschlicher Finger, in den Bewegungsweg der Scheibe gelangt, selbst dann, wenn die Scheibe noch ziemlich weit entfernt von ihrer Schließstellung ist.It is the object of the invention. a fixture me the preamble of claim 1 to indicate that in the window without taking up much space Frame of the window is adapted to be attached, already responds when an object with the temperature of a warm-blooded animal, such as a human finger, gets into the path of movement of the disc itself when the disc is still a long way from its closed position.
Die Lösung dieser Aufgabe ist im Kennzeichen des Anspruchs 1 angegeben.The solution to this problem is given in the characterizing part of claim 1.
Der pyroelektrische Sensor spricht auf einen beispielsweise in den Bewegungsweg der Scheibe gesteckten Finger eines Menschen bereits an, wenn die Scheibe den Finger noch nicht einmal berührt hat.The pyroelectric sensor speaks to you for example A person's finger stuck in the path of movement of the disc is already affected when the disc hasn't even touched the finger.
Um zu vermeiden, daß Langzeiteffekte, etwa eine allmähliche Anwärmung der halboffenen Fensterscheibe, zu einer Auslösung des Sensors führen, ist bevorzugt eine Ausbildung gemäß Anspruch 2 vorgesehen. Eine Steuerschaltung dieser Art ist an sich nach der DE-OS 31 11 681 bekannt.To avoid long-term effects, such as gradual heating of the half-open window pane, lead to a triggering of the sensor, an embodiment according to claim 2 is preferably provided. One Control circuit of this type is known per se from DE-OS 31 11 681.
Um die Ansprechempfindlichkeit des Sensors zu erhöhen, ist bevorzugt eine Ausbildung gemäß Anspruch 3 vorgesehen, insbesondere gemäß Anspruch 4.In order to increase the sensitivity of the sensor, an embodiment according to claim is preferred 3 provided, in particular according to claim 4.
Die Ansprechempfindlichkeit des Sensors läßt sich weiter erhöhen, wenn man gemäß Anspruch 5 vorgeht.The sensitivity of the sensor can be increased further if one proceeds according to claim 5.
Eine besonders hohe Empfindlichkeit gegenüber sich zeitlich rasch ändernder Wärmestrahlung, die durch die Erfindung zu erfassen ist, erhält man mit einer Ausbildung gemäD Anspruch 6. Eine Bewegung eines in den Weg der Fensterscheibe gesteckten Fingers führt dazu, daß die Facetten, die dessen Wärmestrahlung ausgesetzt sind, wechseln. Dadurch ergibt sich ein kurzfristiger Signalabfall des Sensors, der meßtechnisch sehr leicht erfaßt werden kann. Die einzelnen Facetten können dabei gemäß Anspruch 7, im übrigen aber zu einem der oben beschriebenen Hohlspiegel aneinandergesetzt sein.A particularly high sensitivity to thermal radiation that changes rapidly over time, which is caused by the Invention is to be covered, is obtained with a training according to claim 6. A movement of one in the Finger stuck away from the window pane leads to the fact that the facets are exposed to its thermal radiation are, switch. This results in a short-term signal drop in the sensor, which is very much in terms of measurement technology can be easily grasped. The individual facets can according to claim 7, but otherwise to one the concave mirror described above be placed together.
Eine Ansprechzeit des Sensors im Bereich von 1Ao Sekunden reicht in der Praxis aus.A response time of the sensor in the range of 1 seconds is sufficient in practice.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels unter Hinweis auf die Zeichnung beschrieben. The invention is described below using an exemplary embodiment with reference to the drawing.
F i g. 1 zeigt einen Sensor im Querschnitt,
F i g. 2 zeigt den Sensor nach F i g. 1 in Blickrichtung Il in F i g. 1.F i g. 1 shows a sensor in cross section,
F i g. 2 shows the sensor according to FIG. 1 in the direction of view II in FIG. 1.
Der Sensor weist einen Leichtmetallgußkörper 2 auf, der in seinen Außenumrissen im Querschnitt die Form eines Dreiecks mit einer abgeschnittenen Spitze hat. Die Frontansicht 4 des Sensors ist in ihren Außenumrissen rechteckig. Von der Frontseite 6 aus weist der Sensorkörper 2 eine parabolische Aushöhlung 8 in Form eines so Streifens auf, die durch etwa einander parallele Seitenwände 10, 12 begrenzt ist. Von der Oberfläche 14 des Sensorkörpers 2 geht eine Bohrung 16 bis in den von den Flächen 8,10,12 umschlossenen Raum aus. In diese Bohrung ist der Sensor 18 gesteckt und an dem Sensorkörper 2 in nicht dargestellter Weise gehaltert. Der empfindliche Bereich 20 des Sensors 18 liegt etwa im Brennpunkt der Parabolfläche 8.The sensor has a light metal cast body 2, which has the shape in its outer contours in cross section of a triangle with a truncated tip. The front view 4 of the sensor is in its outer contours rectangular. From the front side 6, the sensor body 2 has a parabolic cavity 8 in the form of a so on the strip, which is delimited by approximately parallel side walls 10, 12. From the surface 14 of the Sensor body 2 has a bore 16 extending into the space enclosed by surfaces 8,10,12. In these The sensor 18 is inserted into the bore hole and held on the sensor body 2 in a manner not shown. Of the sensitive area 20 of sensor 18 lies approximately in the focal point of parabolic surface 8.
