Description

Sitzschale
Beschreibung
== ==========
Eine einstückige Sitzschale 10 hat eine Lehne 12 und eine Sitzfläche 14, die über einen gekrümmten Übergangsabschnitt 16 verbunden sind. Um bei steifem Grundmaterial (z.b. dickem Sperrholz) ein federndes Auslenken der Lehne 12 bezüglich der Sitzfläche 14 zu ermöglichen, sind im Übergangsbereich 16 und ggf. in den benachbarten Endbereichen von Lehne 12 und Sitzfläche 14 zu beiden Seiten der Sitzschale jeweils in Querrichtung verlaufende Einschnitte 18 vorgesehen. Diese können parallel zu einander exakt in Querrichtung verlaufen; einige können auch unter leichtem Winkel angestellt sein, nach Art eines Strahlbüschels. Die Einschnitte 18 können alle gleich lang sein oder unterschiedlich lang wie bei 18' gezeigt.
Gestrichelte Linien 20 bzw. 20' begrenzen den einen für die Federwirkung wirksamen Bereich 22 der Sitzschale.
Man erhält so bei von Hause aus durch die Wahl des Grundma- teriales oder die Formgebung (Krümmung auch in Querrichtung, z.B. von der Sitzmitte zu den Seiten ansteigend) steifen Sitzschalen eine Feder zwischen Lehne und Sitzfläche bei glatt von der Lehne zur Sitzfläche durchgehender Randkontur der Sitzschale, die so mit einfach geschnittenen Bezügen einfach bezogen werden kann.
