Door system with a deceleration mechanism

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

• a deceleration mechanism that is attached to a lower region of the door panel and comprises:
• a bolt,
• a bolt moving mechanism that is attached to the bolt,
• a latch mechanism that is removably connected to the bolt moving mechanism and adapted to block the bolt moving mechanism in a normal mode and to release the bolt moving mechanism in a deceleration mode,
• an activation mechanism that is attached to the latch mechanism and adapted to switch the latch mechanism from the normal mode to the deceleration mode when a predetermined air pressure difference threshold between the compartments of the aircraft is exceeded, and
• a brake element that is rigidly attached to the bolt, wherein the bolt moving mechanism, upon release, presses the bolt against the brake element such that the brake element pushes against the floor structure, thereby decelerating the rotational movement of the door panel.
