Abstract
A three-place aircraft divan configured to be installed side-facing in an aircraft and track between an upright sitting position and a berth position. Seat bottom and backrest portions of the divan are movably supported on a static frame and track together. The divan includes inflatable passenger restraints at each seat place and a leg flail prevention device at one end of the frame triggered to actuate in response to an event sensed by a mechanical crash sensor. The inboard leg arrangement of the divan accommodates the installation of two containers for containing high-capacity life rafts under the seat bottom frame, among other equipment.
Claims15
A three-place berthing aircraft divan, comprising:
- a fixed frame comprising a seat bottom frame and a backrest frame;
- first, second and third inboard legs affixed to the seat bottom frame;
- a seat bottom comprising a tracking platform supported by the seat bottom frame and movable relative thereto to track between an upright sitting position and a berth position;
- a backrest comprising a back follower supported by the backrest frame and movable relative thereto, the back follower and the tracking platform linked such that the back follower and the tracking platform track together between the upright sitting position and the berth position;
- a passenger restraint provided at each seat place, each passenger restraint including a lap belt anchored to the tracking platform and a should harness detachable from the lap belt;
- and
- an automatic leg flail prevention device disposed at one end of the seat bottom frame;
- wherein the tracking platform interlocks with the seat bottom frame and each of the lap belts are affixed to an outboard tube of the tracking platform such that each of the lap belts track inboard with the tracking platform and loading on each of the lap belts is transferred to the seat bottom frame through the tracking platform.
A three-place berthing aircraft divan adapted to be installed side-facing in an aircraft cabin, comprising:
- a fixed frame comprising a seat bottom frame and a backrest frame affixed to the seat bottom frame;
- a plurality of inboard legs affixed to the seat bottom frame;
- a seat bottom supported by the seat bottom frame and comprising a tracking platform movable relative to the seat bottom frame to track between an upright sitting position and a berth position of the aircraft divan;
- a backrest supported by the backrest frame and comprising a back follower movable relative to the backrest frame to track the aircraft divan between the upright sitting position and the berth position;
- a passenger restraint provided at each seat place comprising a lap belt anchored to the tracking platform and an inflatable should harness detachable from the lap belt;
- a leg flail prevention device disposed under one end of the seat bottom frame;
- and
- a mechanical crash sensor unit including a processor configured to sense a crash event, and in response to the sensed crash event, trigger inflation of each inflatable should harness and deploy the leg flail prevention device;
- wherein the tracking platform and the back follower are pivotably attached such that the seat bottom and the backrest track together relative to the frame between the upright sitting position and the berth position;
- and
- wherein one end of each inflatable shoulder harness is wound on a retractor affixed under the seat bottom frame, wherein a length of the inflatable shoulder harness remains outside of the retractor such that the retractor provides unceasing tension on the inflatable shoulder harness.
