Abstract

Aircraft seat actuator 1 includes light source 40 and detector 50, 60 detecting a change in light signal from the source and producing an end-of-travel signal received by a controller 8. Second aspect: A detectable member mountable on a rotatable shaft of an actuator. A sensor detects when detectable member completes a revolution and produces a signal. Third aspect: An output shaft of a linear actuator is connected to a fastener via a connecting member, which has a magnet between output shaft and fastener. A magnetic sensor is mounted on the actuator housing. Fourth aspect: An aircraft seat actuator has a position detector measuring position of an output shaft of the actuator, an ammeter measuring current drawn by the actuator, and a controller to shut-down the actuator if the current exceeds a threshold. The threshold is a function of the position of the output shaft. Fifth aspect: An aircraft seat actuator includes a gearbox having a housing constructed of polyamide. Sixth aspect: An aircraft seat linear actuator has a lead screw and nut, constructed of carbon-fibre reinforced polyamide impregnated with PTFE lubricant. Seventh aspect: An aircraft seat actuator has a gearbox with a non-circular profile for receiving an output shaft.
