  Luftpolster mit   Lüftungskanal   
Die Erfindung betrifft einen Luftpolster mit Lüftungskanal, hergestellt aus einer   Gummiplatte   mit separatem Stoffüberzug, welcher vorzugsweise als keilförmiger Kopfpolster verwendet werden kann. 



   Fig. 1 zeigt den Gegenstand mit dem exzentrisch angeordneten   doppeltriehterförmigen   Lüftungs-   kanal. Dieser bewirkt bei der Keilform des Polsters im aufgeblasenen Zustand für den Kopf eine Mulde, welche eine stabilere Kopflagerung gewährleistet.   



   Fig. 2 zeigt den aufgeblasenen Polster in Seitenansicht und veranschaulicht den   trichterförmigen  
Lüftungskanal B, welcher in der Mitte eine   Gummischlauchversteifung   C aufweist. Diese verhindert ein Absperren des   Lüftungskanales   im aufgeblasenen Zustande. 



   Den ganzen Gummipolster umgibt ein Hülle   A   aus dünnem Stoffgewebe, welche die Luft durch   den Lüftungskanal leicht durchströmen   lässt. 



   Fig. 3 zeigt den   trichterförmigen   Lüftungskanal. 



   PATENT-ANSPRÜCHE :
1. Luftpolster mit Lüftungskanal, dadurch gekennzeichnet, dass der vorzugsweise doppeltrichter- förmige LÜftungskanal des Polsters in der Mitte eine Versteifung aufweist, welche im   aufgeblasenen  
Zustande des Polsters ein Zusammendrücken des Lüftungskanals verhindert.

  Air cushion with ventilation duct
The invention relates to an air cushion with a ventilation duct, made from a rubber plate with a separate fabric cover, which can preferably be used as a wedge-shaped head cushion.



   Fig. 1 shows the object with the eccentrically arranged double-string-shaped ventilation duct. With the wedge shape of the pad when it is inflated, this creates a recess for the head, which ensures a more stable head positioning.



   Fig. 2 shows the inflated cushion in side view and illustrates the funnel-shaped one
Ventilation duct B, which has a rubber hose stiffener C in the middle. This prevents the ventilation duct from being blocked when it is inflated.



   The entire rubber cushion is surrounded by a cover A made of thin fabric, which allows the air to flow easily through the ventilation duct.



   Fig. 3 shows the funnel-shaped ventilation duct.



   PATENT CLAIMS:
1. Air cushion with ventilation duct, characterized in that the preferably double funnel-shaped ventilation duct of the cushion has a stiffener in the middle, which in the inflated
Condition of the cushion prevents the ventilation duct from being compressed.
