International Classification:

B60N002/22

US Classification:

297/362110

Abstract:

A no-back drive mechanism for use in aircraft seat actuator assemblies. The mechanism provides a general interface between an electric motor and a seat actuator. The mechanism prevents an aircraft seat actuator from back driving under passenger induced loads on the seat. The no-back drive mechanism comprises an input member, an output member, and a housing. The input and output members include driving and driven members respectively. The driven members include cam surfaces on which ride rolling members. The cam surfaces are designed to cause the rolling members to wedge against the cam surfaces and the housing when the output member experiences either clockwise or counter-clockwise rotation due to passenger induced loads on the aircraft seat actuator assembly. The driving members of the input member, by contrast, include features which disengage the rolling members from their locked positions and transmit torque to the driven members of the output member, thereby allowing the input member to freely drive the output member in both clockwise and counter-clockwise directions.

Abstract:

A vehicle seat system includes a vehicle seat, a main controller, a plurality of hub controllers connected to the main controller, and a plurality of seat devices operatively coupled to the seat. Each seat device is connected to a corresponding one of the hub controllers and operatively coupled to the main controller through the hub controllers. At least two of the seat devices are connected to a single one of the hub controllers.
