  • For upholstery it is also important to achieve a pleasant compression hardness. In the case of a sound-absorbing effect is desirable.
  • Another object is to propose a method for producing such furniture components.
  • the furniture component for upholstery or as a component has an outer covering, which results from the addition of a plastic.

Abstract

Composant de meuble (9) pour rembourrage ou en tant qu'élément de construction, qui possède une enveloppe extérieure (3, 4) produite par apport d'une matière plastique dans la cavité (10, 20) d'un moule (M). Il possède extérieurement une structure de surface définie, qui constitue une image symétrique d'une structure de surface de la cavité (10, 20) créée de manière ciblée. L'enveloppe (3, 4) est produite par pulvérisation de la matière plastique dans la cavité (10, 20) du moule (M) ou par introduction de matière plastique dans la cavité (10, 20) et par répartition de la matière plastique dans le moule fermé (M) par rotation du moule (M) dans un plan. L'enveloppe (3, 4) entoure le composant de meuble (9) totalement ou seulement partiellement, et dans une épaisseur uniforme ou sélectivement différente par zones. Selon une variante, le composant de meuble est rempli d'air et/ou d'une charge (6), notamment d'une mousse molle ou d'un granulat, et il peut contenir au moins un insert (5) résistant à la flexion. Selon une autre variante, le composant de meuble contient un insert (5) résistant à la flexion, de préférence une plaque, par exemple en matériau dérivé du bois, qui est pourvu de l'enveloppe (3, 4) au moins sur une surface. Si le composant de meuble possède un remplissage d'air et/ou contient la charge (6), une soupape peut être montée dans l'enveloppe (3, 4) ou dans l'insert (5). L'enveloppe (3, 4) et la charge (6) sont constituées de polyuréthane, l'enveloppe (3,4) pouvant aussi être du gel de polyuréthane. Le composant de meuble qui est rempli d'air ou contient une charge (6) sous la forme d'une mousse molle ou d'un granulat sert de rembourrage sur un meuble d'assise ou de couchage, pour l'assise, le dossier, les accoudoirs ou les appuie-tête de ce meuble. Le composant de meuble qui est constitué uniquement d'un insert (5) entouré par l'enveloppe (3, 4) est utilisé comme plateau de table, comme matériau sous forme de plaque pour des meubles à corps ou comme coque de siège.
