The accessibility door may be coupled to the privacy shell via at least one actuation assembly. The accessibility door may be configured to actuate between an open position and a closed position via the at least one actuation assembly. The privacy shell may be coupled to the privacy shell base. At least a portion of the privacy shell may be configured to conform to at least a portion of the aircraft seat. The privacy shell base may be configured to support the accessibility door at a height above a floor of an aircraft cabin including the aircraft passenger compartment. The height may be selected to allow access to the aircraft seat over the privacy shell base when the accessibility door is in the open position. ## Claims ### Claim 1 An aircraft passenger compartment, comprising: an accessibility door; a privacy shell, the accessibility door coupled to the privacy shell via at least one actuation assembly, the accessibility door configured to actuate between an open position and a closed position via the at least one actuation assembly, the at least one actuation assembly including: at least one rotation assembly and at least one translation assembly, the accessibility door and the privacy shell separated by a distance configured to change as the accessibility door actuates between the open position and the closed position, the accessibility door configured to actuate between the open position and the closed position via the at least one rotation assembly and the at least one translation assembly, the accessibility door configured to rotate about one or more vertical axes into an open position against the privacy shell via the at least one rotation assembly and the accessibility door configured to translate along at least one track and at least one slider, the accessibility door including a range of actuation having a select angle of rotation between the closed position and the open position via the at least one rotation assembly, the angle of rotation increasing during the transition between the closed position and the open position, the angle of rotation decreasing during the transition between the open position and the closed position; an aircraft seat; and a privacy shell base, the privacy shell being coupled to the privacy shell base, at least a portion of the privacy shell configured to conform to at least a portion of the aircraft seat, the privacy shell base configured to support the accessibility door at a height above a floor of an aircraft cabin including the aircraft passenger compartment, the height selected to allow access to the aircraft seat over the privacy shell base when the accessibility door is in the open position. ### Claim 2 (depends on 1) The aircraft passenger compartment of claim 1, the privacy shell including one or more privacy shell elements, at least one privacy shell element of the one or more privacy shell elements configured to conform to the at least the portion of the aircraft seat. ### Claim 3 (depends on 1) The aircraft passenger compartment of claim 1, the at least one slider configured to actuate along the at least one track. ### Claim 4 (depends on 3) The aircraft passenger compartment of claim 3, the at least one track coupled to the privacy shell base, the at least one slider coupled to the accessibility door. ### Claim 5 (depends on 1) The aircraft passenger compartment of claim 1, comprising: an interlocking assembly, the interlocking assembly configured to couple the accessibility door to the privacy shell base when the accessibility door is in the closed position. ### Claim 6 (depends on 5) The aircraft passenger compartment of claim 5, the accessibility door configured to operate as a privacy shell element of the privacy shell when the accessibility door is in the closed position and the interlocking assembly couples the accessibility door to the privacy shell base. ### Claim 7 (depends on 1) The aircraft passenger compartment of claim 1, the at least one rotation assembly including a first linkage and a second linkage, the first linkage and the second linkage each being coupled to the privacy shell via one or more hinge joints, the first linkage and the second linkage each being coupled to the accessibility door via one or more additional hinge joints. ### Claim 8 (depends on 7) The aircraft passenger compartment of claim 7, the first linkage being greater in length than the second linkage. ### Claim 9 (depends on 7) The aircraft passenger compartment of claim 7, at least one of the first linkage or the second linkage including a curved section. ### Claim 10 (depends on 1) The aircraft passenger compartment of claim 1, comprising: an armrest, the armrest configured to be actuated between a stowed position and a deployed position, the armrest configured to be in the stowed position to allow access to the aircraft seat over the armrest when the accessibility door is in the open position. ### Claim 11 (depends on 10) The aircraft passenger compartment of claim 10, the privacy shell base configured to conform to a portion of the armrest when the armrest is in the stowed position. ### Claim 12 (depends on 11) The aircraft passenger compartment of claim 11, a top surface of the privacy shell base and a top surface of the armrest being the height from the floor of the aircraft cabin. ### Claim 13 An aircraft passenger compartment, comprising: a privacy shell, the accessibility door coupled to the privacy shell via at least one actuation assembly, the accessibility door configured to actuate between an open position and a closed position via the at least one actuation assembly, the at least one actuation assembly including: at least one rotation assembly and at least one translation assembly, the accessibility door and the privacy shell separated by a distance configured to change as the accessibility door actuates between the open position and the closed position, the accessibility door configured to actuate between the open position and the closed position via the at least one rotation assembly and the at least one translation assembly, the accessibility door configured to rotate about one or more vertical axes into an open position against the privacy shell via the at least one rotation assembly and the accessibility door configured to translate along at least one track and at least one slider, the accessibility door including a range of actuation having a select angle of rotation between the closed position and the open position via the at least one rotation assembly, the angle of rotation increasing during the transition between the closed position and the open position, the angle of rotation decreasing during the transition between the open position and the closed position; an aircraft seat; and a privacy shell base, the privacy shell being coupled to the privacy shell base, at least a portion of the privacy shell configured to conform to a backrest of the aircraft seat, the privacy shell base configured to support the accessibility door at a height above a floor of an aircraft cabin including the aircraft passenger compartment, the height selected to allow access to the aircraft seat over the privacy shell base when the accessibility door is in the open position.
