Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Schaum-Formstückes, welches auf der dem Betrachter zuge wandten Seite mit einem geprägten Lederkleid versehen ist, gemäß den Merkmalen des Oberbegriffs des Anspruchs 1. Die Erfindung bezieht sich ferner auf ein Formstück, hergestellt nach diesem Verfahren.The invention relates to a method for producing a Foam molding, which on the viewer embossed leather dress, according to the features of the preamble of claim 1. Die The invention further relates to a molded article manufactured according to this procedure.
Derartige Schaum-Formstücke finden insbesondere als Innentei le in Kraftfahrzeugen, etwa als Instrumententafeln, Airbagab deckungen, Polster etc., Verwendung. Zur Herstellung des je weiligen Schaum-Formstückes wird üblicherweise zunächst ein Lederkleid aus einzelnen Lederteilstücken zusammengenäht. Die Nähte werden dann einzeln mittels entsprechender Dichtbahnen abgedichtet, damit beim späteren Hinterschäumen des Leder kleides kein Schaum durch die Nähte gedrückt wird. Anschlie ßend wird das Lederkleid geprägt, das geprägte Lederkleid in die Schäumform eingelegt, randseitig mit einem Klebeband ab gedichtet und dann hinterschäumt. Dabei kann gegebenenfalls zur Erhöhung der Stabilität des Formstückes eine Einlage mit eingeschäumt werden. Such foam moldings are used in particular as an inner part le in motor vehicles, for example as instrument panels, airbags covers, upholstery etc., use. To make the ever because foam molding is usually first a Leather dress sewn together from individual leather sections. The Seams are then cut individually using appropriate sealing sheets sealed so that when the leather is later foamed no foam is pressed through the seams. Then The leather dress is embossed, the embossed leather dress in the foam mold inserted, with an adhesive tape on the edge sealed and then foamed. This can be done if necessary to increase the stability of the fitting with an insert be foamed.
Nachteilig ist bei diesem bekannten Verfahren der hohe Auf wand, der sowohl mit dem Abdichten der einzelnen Nähte als auch mit dem Abdichten des Lederrandes in der Schäumform verbunden ist. Außerdem besitzt das jeweilige Lederkleid häufig nicht überall die gleiche Wandstärke, so daß der Schaum in einzelnen Bereichen des Lederkleides durch dieses hindurchschimmern kann und zu einem unerwünschten Hellig keitsmuster führt.The disadvantage of this known method is the high up wall, both with the sealing of the individual seams as also with the sealing of the leather edge in the foam form connected is. In addition, the respective leather dress often not the same wall thickness everywhere, so that Foam in individual areas of the leather dress through this can shimmer through and become an undesirable brightness pattern.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs erwähnten Art anzugeben, bei dem vor allem das zeit aufwendige Abkleben der Ledernähte entfallen kann. Ferner soll ein Schaum-Formstück offenbart werden, welches mittels des erfindungsgemäßen Verfahrens herstellbar ist.The invention has for its object a method of Specify the type mentioned above, in which above all the time elaborate masking of the leather seams can be omitted. Further a foam molding is to be disclosed, which means of the method according to the invention can be produced.
Diese Aufgabe wird hinsichtlich des erfindungsgemäßen Verfah rens durch die Merkmale des kennzeichnenden Teils des An spruchs 1 und hinsichtlich des erfindungsgemäßen Schaum- Formstückes durch die Merkmale des kennzeichnenden Teils des Anspruchs 5 gelöst. Weitere besonders vorteilhafte Ausge staltungen der Erfindung offenbaren die Unteransprüche.This object is achieved with regard to the method according to the invention rens by the characteristics of the characterizing part of the An claim 1 and with regard to the foam according to the invention Fitting by the features of the characterizing part of the Claim 5 solved. More particularly advantageous Ausge Events of the invention disclose the subclaims.
Die Erfindung beruht auf dem Gedanken, an dem Lederkleid auf der der Schaumschicht zugewandten Seite eine durchgehende Fo lie zu befestigen, wobei der Befestigungsvorgang vorzugsweise zusammen mit dem Prägen des Lederkleides erfolgt, so daß das separate Abkleben der einzelnen Nähte entfällt.The invention is based on the idea of the leather dress a continuous Fo. the side facing the foam layer lie to fasten, the fastening process preferably takes place together with the embossing of the leather dress, so that the separate masking of the individual seams is not necessary.
Sofern die Folie sich bis zu dem Rand des Lederkleides er streckt, kann zur Abdichtung der Schäumform auf ein zusätz liches Klebeband verzichtet werden, weil dieses Abdichten durch die Folie mit übernommen wird. Unless the film extends to the edge of the leather dress stretches, can be used to seal the foam mold on an additional Lich tape is dispensed with because of this sealing is taken over by the film.
Schließlich kann auf einfache Weise durch die Wahl der Wand stärke der Folie und durch seine Farbgebung vermieden werden, daß nach dem Hinterschäumen des Lederkleides der Schaum an den Stellen, an denen das Lederkleid eine geringe Wandstärke aufweist, durch das Leder hindurchschimmert.Finally, it can be done easily by choosing the wall thickness of the film and its coloring can be avoided, that after foaming the leather dress the foam on the places where the leather dress has a thin wall has shimmering through the leather.
Als Folienmaterial hat sich vor allem Polyurethan bewährt. Die Wandstärke der Folie sollte mindestens 0,03 mm betragen.Polyurethane in particular has proven itself as a film material. The wall thickness of the film should be at least 0.03 mm.
