Abstract
Description
Die Erfindung betrifft eine Heizmatte für einen Kraftfahrzeugsitz, wobei eine Thermoplastmatte ein Elektroheizelement aufnimmt.The invention relates to a heating mat for a motor vehicle seat, a thermoplastic mat accommodates an electric heating element.
Die DE 41 22 363 C1 beschreibt eine Heizmatte aus mehreren, miteinander verklebten Schichten, bei der in den Schichtaufbau zwischen zwei Schichten ein Elektroheizelement eingefügt ist. Der mehr schichtige Aufbau erfordert eine zeitaufwendige Montage, insbesondere wegen der Klebearbeiten.DE 41 22 363 C1 describes a heating mat made of several layers glued together, in which an electrical heating element is inserted into the layer structure between two layers. The more layered structure requires a time-consuming assembly, especially because of the adhesive work.
Aufgabe der Erfindung ist die Bereitstellung einer einschichtigen Heizmatte, die einfach und zeit sparend herstellbar ist.The object of the invention is to provide a single-layer heating mat that is simple and time can be produced economically.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß das Elektroheizelement etwa in der Mittelebene der als Spritzgießteil ausgebildeten Thermoplastmatte angeordnet ist.This object is achieved according to the invention in that the electric heating element approximately in the Middle plane of the thermoplastic mat designed as an injection molded part is arranged.
Die Erfindung unterscheidet sich insofern vom Stand der Technik, als das Elektroheizelement durch die Thermoplastmatte umspritzt ist. Das Elektroheizelement ist also sozusagen in die Ther moplastmatte integriert. Ein Verbinden des Elektroheizelements mit der Thermoplastmatte entfällt.The invention differs from the prior art in that the electric heating element is encapsulated by the thermoplastic mat. The electric heating element is so to speak in the Ther integrated mop mat. There is no need to connect the electric heating element to the thermoplastic mat.
Eine Anpassung an den lokalen Wärmebedarf der Heizmatte ist dadurch möglich, daß das Heizele ment als schlangenförmiger oder mäanderförmiger, in der Mittelebene der Thermoplastmatte ausgelegter Heizdraht ausgebildet ist.An adaptation to the local heat requirement of the heating mat is possible in that the Heizele ment as a serpentine or meandering, laid out in the central plane of the thermoplastic mat Heating wire is formed.
Eine Anpassung an den Fahrzeugsitz wird dadurch erzielt, daß die Heizmatte aus einem thermopla stischen Elastomeren besteht.An adaptation to the vehicle seat is achieved in that the heating mat from a thermopla elastic elastomers.
Des weiteren betrifft die Erfindung ein Verfahren zur Herstellung einer Heizmatte durch Spritzgie ßen des thermoplastischen Elastomeren, wonach innerhalb einer Formkammer des geöffneten Spritzgieß werkzeugs der Heizdraht ausgelegt und nach dem Schließen des Spritzgießwerkzeugs mit einem ther moplastischen Elastomeren umspritzt wird.The invention further relates to a method for producing a heating mat by injection molding ß of the thermoplastic elastomer, after which within a mold chamber of the opened injection molding the heating wire and after closing the injection mold with a ther is molded around plastic elastomers.
Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung erläutert, in der darstellen:An embodiment of the invention is explained with reference to the drawing, in which:
Fig. 1 eine Draufsicht auf die Heizmatte und Fig. 1 is a plan view of the heating mat and
Fig. 2 einen Schnitt nach der Linie II-II in Fig. 1. Fig. 2 shows a section along the line II-II in FIG. 1.
Die Heizmatte nach den Fig. 1 und 2 umfaßt eine Thermoplastmatte 1 aus einem thermoplastischen Elastomeren und ein etwa in der Mittelebene der Thermoplastmatte 1 angeordnetes Elektroheizelement in Form eines schlingenförmig oder mäanderförmig, ausgelegten Heizdrahtes 2, dessen Enden an eine An schlußvorrichtung 3 angeschlossen sind.The mat according to FIGS. 1 and 2 comprises a thermoplastic mat 1 made of a thermoplastic elastomer and which is arranged approximately in the center plane of the thermoplastic mat 1 electric heating element in the form of a loop-shaped or meander-shaped, designed heating wire 2, the ends of which circuit device to a to 3 are connected.
Der Heizdraht 2 wird etwa in der Mittelebene einer Formkammer des geöffneten Spritzgießwerk zeugs durch eine Handlingvorrichtung in der gewünschten Form ausgelegt. Nach Schließen des Spritz gießwerkzeugs wird ein thermoplastisches Elastomeres in die Formkammer eingespritzt. Nach dem Öff nen des Spritzgießwerkzeugs kann man die Heizmatte in der dargestellten Form entnehmen.The heating wire 2 is approximately in the central plane of a mold chamber of the opened injection molding machine designed by a handling device in the desired shape. After closing the injection mold, a thermoplastic elastomer is injected into the molding chamber. After opening the injection mold, the heating mat can be removed in the form shown.
