A deployable attendant seat assembly that is configured to deploy in a vehicle cabin from a stowed position as an attendant seat into a deployed position configuring the deployable attendant seat assembly into a lockable barrier to prevent passengers from moving along an aisle in a vehicle cabin into a vehicle area forward of the lockable barrier.

A dual purpose aircraft lavatory component that can be a dual purpose aircraft lavatory door that is configured to deploy in a vehicle cabin from an initial position as an aircraft lavatory monument component into a deployed position converting aircraft lavatory monument component into an aircraft cabin lockable barrier to prevent passengers from moving along an aisle in a vehicle cabin into a vehicle area forward of the lockable barrier.

A hybrid aircraft barrier that is configured to deploy in a vehicle cabin from an initial stowed position as an aircraft cabin monument component into a deployed position converting the aircraft cabin monument component into an aircraft cabin lockable barrier to prevent passengers from moving along an aisle in a vehicle cabin into a vehicle area forward of the lockable barrier.

A device for preventing access to an area of an aircraft includes a first vertical frame post designed for attachment to a structure of the aircraft, a second vertical frame post designed for attachment to a structure of the aircraft, a barrier element displaceably connected to the first frame post and including a latching element for detachable connection of the barrier element to the second frame post, and a delay unit including a spring-loaded damping cylinder displaceable into a damping position by a locking movement in opposition to a spring force. The delay unit is designed to release the latching element after a time delay.

A barrier door system to control movement of persons through an opening within a cabin area of an aircraft. The barrier door system includes a track with an elongated shape with a first end and a second end. A barrier door includes panels that are pivotally connected together and one or more pins that extend outward from a top edge of the barrier door and are configured to engage with the track. The panels are configured to pivot together in a folded configuration at a stowed position, and to pivot outward away from the track in an extended configuration to extend across the opening at the deployed position.

A deployable attendant seat assembly that is configured to deploy in a vehicle cabin from a stowed position as an attendant seat into a deployed position configuring the deployable attendant seat assembly into a lockable barrier to prevent passengers from moving along an aisle in a vehicle cabin into a vehicle area forward of the lockable barrier.

A hybrid aircraft barrier that is configured to deploy in a vehicle cabin from an initial stowed position as an aircraft cabin monument component into a deployed position converting the aircraft cabin monument component into an aircraft cabin lockable barrier to prevent passengers from moving along an aisle in a vehicle cabin into a vehicle area forward of the lockable barrier.

An aircraft includes a flight deck including a flight deck door configured to be moved between an open position and a closed position, a first monument, second monument, and a secondary barrier door moveably secured between the first monument and the second monument. The secondary barrier door is configured to fold into a stowed position in which a path to the flight deck is open, and unfold into a deployed position in which the path to the flight deck is closed.

An aircraft section, between a cockpit and a cabin, comprises an aisle to access to the cockpit from the cabin, and a monument extending in a longitudinal direction and a transverse direction. The monument includes a first lavatory, a second lavatory adjacent thereto in the transverse direction and comprising the aisle, a wall separating the first lavatory from the second lavatory, a boundary wall delimiting the first lavatory and a portion of a rear wall of the cockpit, and a second boundary wall delimiting the second lavatory and a second portion of the rear wall of the cockpit. The boundary walls are parallel or continuous. The monument further includes an outer door movable between an open position, where the cockpit aisle is accessible from the cabin area, and a closed position, where the cockpit aisle is blocked with respect to the cabin area.

An aircraft includes a flight deck including a flight deck door configured to be moved between an open position and a closed position, a first monument, second monument, and a secondary barrier door moveably secured between the first monument and the second monument. The secondary barrier door is configured to fold into a stowed position in which a path to the flight deck is open, and unfold into a deployed position in which the path to the flight deck is closed.
