摘要： A pneumatic module has an air passage formed therein, including an air inlet to receive a source of pressurized air, a first subsystem with an air splitter in fluid communication with the air inlet, a second subsystem, and a third subsystem. The air splitter is configured to create two unequal air pressure fields to deflect an airflow from the air inlet to the second subsystem. The second subsystem is configured to create two unequal air pressure fields to deflect the airflow toward a first air bladder to inflate the first air bladder, and when the first air bladder reaches a first threshold air pressure, a first backpressure from the first air bladder causes the second subsystem to switch and deflect the air flow to a second air bladder. A second backpressure causes the air splitter to switch and deflect the airflow from the second subsystem to the third subsystem.

摘要： A method for configuring a controller to operate a motor to position a seat, in which the controller includes an integrated current sensor and the seat includes a latch operatively coupled to the motor, includes determining an operating profile of the motor under one or more operating conditions, wherein the operating profile represents motor current values during activation of the latch, and wherein the activation of the latch includes at least one latch pulling condition and one latch release condition. The method further includes analyzing the operating profile in order to correlate the profile to the position of the latch. The method also includes loading the controller with instructions to enable comparison of a real-time current measured by the integrated current sensor to the stored operating profile, wherein the analysis enables determination of the latch condition in real-time.

摘要： An adjustable support system for a seat having a fixed frame includes a support movable from a first position to a second position relative to the frame. An actuator is coupled to only the support and is configured to move the support between the first and second positions. A member is operatively associated with and movable by the actuator. A flexible cable has a first end coupled to the member for travel along the length of the member and a second end coupled to the fixed frame such that movement of the member by the actuator causes the flexible cable to move the support between the first position and the second position.

摘要： An actuator includes a motor, a gear assembly, a pulley selectively rotatable about an axis by the motor via the gear assembly, at least one biasing member, a first cable connected at one end to the pulley, and a second cable connected at one end to the pulley. The pulley is rotatable in a first pulley direction to a first actuation position to increase tension in the first cable and is rotatable in a second pulley direction opposite the first pulley direction to a second actuation position to increase tension in the second cable. The at least one biasing member is operable to bias the pulley in the second pulley direction when the pulley is in the first actuation position and to bias the pulley in the first pulley direction when in the pulley is the second actuation position.
