  • Patent number: 5028016
    Abstract: A modular work station particularly suited for aircraft slidably mounts computer work station seats. The seats and work stations may be oriented in a modular manner with the seat orientation being directed toward the fore or aft ends of an aircraft to enhance operator comfort during long periods of flight. The seats are provided with a swivel capability of at least 180.degree. to enable ingress into a walkway. During landing and take-off, the operator seat has the capability of being latched in a forward- or rearward-facing position to enhance operator safety during these conditions. The seat is slidably mounted along a track that has rear curved portions that allow a seat to slide back to an angular orientation to facilitate an operator's ingress or egress.
