Door system with a deceleration mechanism

A door system adapted to control an opening of a door module that separates compartments of an aircraft, the door module comprising a door panel and a door frame, wherein the door panel performs a rotational movement above is floor structure of the aircraft during an opening of the door module, the door system comprising:

• a deceleration mechanism that is operable in a normal operation mode and a deceleration mode and comprises:
• a hinge, and
• a wedge-shaped component that is rotatably attached to the hinge, wherein during the rotational movement of the door panel from a closed position to any open position:
• the wedge-shaped component is embedded in the floor structure of the aircraft to prevent an interaction with the door panel in the normal operation mode, and
• the wedge-shaped component protrudes from the floor structure of the aircraft and interacts with the door panel such that the rotational movement of the door panel is decelerated at least between a first open position and a second open position in the deceleration mode;
• and
• an activation device that is coupled to the wedge-shaped component and that switches the deceleration mechanism from operating in the normal operation mode to operating in the deceleration mode when a difference in pressure between the compartments exceeds a predetermined threshold.
