  • Publication number: 20180001754
    Abstract: A cabin assembly may comprises a door assembly comprising an outer surface, an inner surface, and a seal. The cabin assembly may further comprise a cabin frame comprising hinge assemblies pivotably coupling the door assembly to the cabin frame and a seal surface defining an opening into the cabin frame. The seal surface may contact and compress the seal of the door when the door assembly is in a closed position. The seal surface may include an angled seal surface that is provided at an angle with respect to the inner surface of the door assembly. The angled seal surface may be located proximate to the hinge assemblies. The angled seal surface may prevent a portion, of the seal of the door, from being compressed above a threshold when the door assembly is in the closed position.
