(EN) VENTILATED MOLDED COVERS FOR SEATING APPLICATIONS
(FR) REVÊTEMENTS MOULÉS VENTILÉS POUR APPLICATIONS DE SIÈGES
Abstract
(EN)
A ventilated molded seat trim cover for a vehicle seat and a ventilated vehicle seat having a ventilated molded seat trim cover, comprising a stacked assembly of an upper textile layer, a first adhesive layer, an air permeable polyurethane cellular foam interlayer thermo- moldable at temperatures between about 104°C and about 127°C, a second adhesive layer, a thermoplastic polyurethane (TPU) film, a third adhesive layer, and a scrim backing layer. The stacked assembly is compression molded in a 3 -dimensional mold while at least a portion of the foam interlayer is heated to a temperature between about 104°C and about 127°C to form the ventilated molded seat trim cover. The TPU film prevents airflow passing through a bottom surface of the seat trim cover. Airflow in the foam interlayer can pass through the upper textile layer.

Un revêtement de garniture de siège moulé ventilé pour un siège de véhicule et un siège de véhicule ventilé ayant un revêtement de garniture de siège moulé ventilé, comprenant un ensemble empilé d'une couche textile supérieure, une première couche adhésive, une couche intermédiaire en mousse cellulaire de polyuréthane perméable à l'air pouvant être moulée thermiquement à des températures comprises entre environ 104 °C et environ 127 °C, une seconde couche adhésive, un film de polyuréthane thermoplastique (TPU), une troisième couche adhésive, et une couche de support de canevas. L'ensemble empilé est moulé par compression dans un moule en trois dimensions tandis qu'au moins une partie de la couche intermédiaire en mousse est chauffée à une température comprise entre environ 104 °C et environ 127 °C pour former le revêtement de garniture de siège moulé ventilé. Le film en TPU empêche le passage d'un flux d'air à travers une surface inférieure du revêtement de garniture de siège. Le flux d'air dans la couche intermédiaire en mousse peut passer à travers la couche textile supérieure.
