Sie ist sowohl höhenverstellbar als auch horizontal dehnbar. Bevorzugt besteht die erfindungsgemäße Vorrichtung aus einem Mittelteil mit zwei vergleichsweise starren Trägerelementen (4), die über ein in der Mitte angeordnetes elastisches Element (5) miteinander verbunden sind und aussen jeweils einen seitlichen Führungssteg (6) aufweisen, wobei die Führungsstege (6) im Rückenlehnenrahmen (1) verschiebbar angeordnet sind, einem auf einer Polsterplatte (9) befestigten Polsterkissen (8) als zur Membran (2) hin angeordnetem Vorderteil sowie einer Kunststoffplatte (10) als Rückteil, wobei das Polsterkissen (8) und die Kunststoffplatte (10) mittels einer Clipverbindung (11) verbunden sind und die Clipverbindung (11) in Langlöchern (12) der Trägerelemente (4) geführt ist.
