20110278891 | MODULAR CONTOUR SUPPORT APPARATUS - A four way lumbar support for an automobile seat includes a wire array, a fixed frame, and a basculating arm. When in its extended position, the basculating arm exerts pressure on the wire array thus providing lumbar support to the seat occupant at that point. A system of cables and sliding connections allows the basculating arm to slide along the fixed frame so that the lumbar support may be provided at different heights within the seat. | 11-17-2011 |
20130306161 | SYSTEM AND METHOD FOR A PRESSURE SIGNAL LINEARIZATION TRANSFER FUNCTION - A method for operating a pneumatic lumbar support between a deflated position and an inflated position. The method includes inflating a bladder of the pneumatic lumbar support; sensing a pressure within the bladder using a pressure sensor; producing an inflation output signal from the pressure sensor, wherein the inflation output signal is a function of time; and converting the inflation output signal using an inflation-deflation transfer function. | 11-21-2013 |
20140070583 | LUMBAR SUPPORT SYSTEM - A lumbar support system for a seat backrest having a fixed frame includes a lumbar support coupled to the fixed frame that is movable from a first position to a second position and a motor for moving the lumbar support. A threaded member is operatively associated with the motor such that the motor rotates the threaded member about an axis. A traveling member is operatively associated with the threaded member such that rotation of the threaded member translates the traveling member along the threaded member. The system further includes a flexible cable having a first end and a second end. The first end is coupled to the traveling member for movement therewith and the second end is coupled to the fixed frame such that translation of the traveling member in response to rotation of the threaded member moves the lumbar support element from the first position to the second position. | 03-13-2014 |

The system further includes a flexible cable having a first end and a second end. The first end is coupled to the traveling member for movement therewith and the second end is coupled to the fixed frame such that translation of the traveling member in response to rotation of the threaded member moves the lumbar support element from the first position to the second position. | 03-13-2014 |
20140125102 | LUMBAR SUPPORT SYSTEM - 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. | 05-08-2014 |
20140191553 | CABLE SYNCHRONIZER SYSTEM - An actuation system for concurrently actuating a first mechanism and a second mechanism from a first state to a second state includes an actuator and a sliding member operatively engaged with the actuator and movable from a first position to a second position in response to actuation of the actuator. A connecting member has a relaxed state and a taut state. The connecting member includes a first end coupled to the first mechanism, a second end coupled to the second mechanism, and a medial portion cooperative with the sliding member. Movement of the sliding member from the first position to the second position changes the connecting member from the relaxed state to the taut state, whereby the tension is increased in the connecting member. | 07-10-2014 |
20140265991 | SYSTEM AND METHOD FOR SENSORLESS REMOTE RELEASE ACTUATING SYSTEM - 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. | 09-18-2014 |
20160059757 | LUMBAR SUPPORT SYSTEM - 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. | 03-03-2016 |
