Electromechanical actuation system for aircraft passenger suites and method
First Claim
1. An electromechanical actuation system for an aircraft passenger suite for allowing passenger-initiated adjustment of a passenger seat and related passenger accoutrements, comprising:
- (a) a suite control unit configured to receive command signals from a user interface; and
(b) a first line replacement unit comprising a first integral electronic control unit and a second line replacement unit coupled to the first line replacement;
(c) wherein the first electronic control unit controls operation of the first line replacement unit and the second line replacement unit in response to command signals received from the suite control unit, wherein;
the second line replacement unit includes a second integral electronic control unit, and the second electronic control unit controls operation of the second line replacement unit in response to user commands received from the suite control unit when the first electronic control unit becomes inoperative.
