Abstract: A child restraint system may provide a seat and restraint system for a child in an aircraft lavatory. The child restraint system may be configured to be installed on an existing wall such as a wall of an aircraft lavatory or be manufactured as part of an aircraft lavatory. The child restraint system may be a rigid structure comprising a seat back, a seat bottom, a first seat side, a second seat side, and a harness. The child restraint system may be a flexible or fabric structure. The child restraint system may comprise a seat, a first strap, and a second strap.

Abstract: An adjustable height fastener may have a fixed receiver connectable to a fixed structure and an extendible member connectable to the fixed receiver at different locations along a first axis. The extendible member may slide relative to the fixed receiver along the first axis and may selectably connect to fix the fixed receiver and the extendible member in a first location along the first axis.

Abstract: An aircraft lavatory monument is provided that includes a first lavatory comprising a first door providing access to the first lavatory from an aisle of an aircraft, a second lavatory proximate the first lavatory, the second lavatory comprising a second door providing access to the second lavatory from the aisle of the aircraft, and a movable wall disposed between the first lavatory and the second lavatory. In a first position, the movable wall separates the first lavatory from the second lavatory providing privacy therebetween. In a second position, the movable wall is translated toward an outer wall of the aircraft lavatory monument thereby combining the first lavatory and the second lavatory.

Abstract: A lavatory door including an ashtray is disclosed herein. The lavatory door includes a door panel having a first side and an opposing second side and the ashtray disposed within the door panel. The ashtray includes a first outer panel disposed along the first side of the door panel and configured to move away from the door panel, a second outer panel, opposite the first outer panel, disposed along the second side of the door panel and configured to move away from the door panel, and a bottom surface extending from the first outer panel to the second outer panel.

Abstract: A T-divider includes a housing defining a proximal end, a distal end, and at least one cavity extending therebetween. The housing extends along a longitudinal axis. The T-divider includes a moveable portion disposed in the housing and extending between the proximal end and the distal end. The movable portion is configured to rotate about the longitudinal axis from a stowed orientation to a removal orientation.

Abstract: An aircraft lavatory is disclosed herein. The aircraft lavatory includes an access door providing access to the aircraft lavatory from at least one of an aisle, a cross aisle, or a passageway of an aircraft, wherein the access door is configured to rotate from a closed position to an open position in a first direction and a moveable wall disposed adjacent the access door, the moveable wall being configured to rotate from a closed position to an open position in a second direction that is opposite the first direction, the moveable wall being configured to receive and secure the access door while the moveable wall is in the closed position, wherein an opening configured to allow ingress of a mobility device into the aircraft lavatory is created in response to the access door being in the open position and the moveable wall being in the open position.

Abstract: An aircraft lavatory monument is provided that includes a first lavatory including a first door providing access to the first lavatory from an aisle of an aircraft; a second lavatory proximate the first lavatory, the second lavatory including a second door providing access to the second lavatory from the aisle of the aircraft; and a movable wall disposed between the first lavatory and the second lavatory, the movable wall including a latching mechanism positioned on an exterior edge of the movable wall and accessible from the aisle of the aircraft, where the latching mechanism, responsive to being in a locked position, causes the movable wall to be positioned at a first position separating the first lavatory from the second lavatory and providing privacy therebetween, and where the latching mechanism, responsive to being in an unlocked position, allows the movable wall to collapse thereby forming an enlarged bathroom space.
