ABSTRACT:
An occupant lumbar support system includes a flexible lumbar support member having homogenously connected first and second connection braces. The lumbar support member is deflectable to a plurality of lumbar support positions. A rigid displacement rod is connected at a first rod end to one of the connection braces. A lumbar member actuation mechanism has a rotatable first actuation arm receiving a second displacement rod end. The actuation member translates the displacement rod causing the first and second connection braces to move toward each other, deflecting the lumbar support member to any of the lumbar support positions. A cable is connected at a first end to an actuation mechanism second actuation arm and at a second end to a displaceable lever manually movable to co-rotate the first and second actuation arms and translate the displacement rod.
