  • 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.

  • Patent number: 9151091
    Abstract: An actuator mechanism for a door latch is provided. The actuator mechanism may include a first actuator and a second actuator. The first actuator can be pivotably coupled to a first support structure about a first axis. Moreover, the first actuator can include an engaging tip, a first engagement and a second engagement. The second actuator can be pivotably coupled to a second support structure about a second axis. In response to the movement of the arm of the second actuator about the second axis, the first engagement of the first actuator can rotate about the first axis to move the engaging tip to release the door latch. Alternatively, in response to the movement of the second engagement of the first actuator, the second engagement of the first actuator can rotate about the first axis to move the engaging tip to release the door latch.
