Abstract
A rotary controlled motion transmission assembly is mounted behind the dashboard of a vehicle and has a knob that extends through the dashboard for rotary actuation by an occupant of the vehicle to move a bulkhead door for controlling the environment within the vehicle. The knob is connected to a cam plate having first and second ramps which rotate upon rotation of the knob. A pair of spring biased plungers, each having a camming surface, operatively engage respective ramps. A pair of cables are connected to the plungers and extend along a circuitous path within flexible conduits to a receiver assembly, such that axial translation of the plungers upon rotation of the control knob, results in axial translation of the cables. The cables are connected to a pulley mounted on a shaft which is connected to the bulkhead door for opening and closing of the door. When the knob is turned, the ramp surfaces move the plungers in opposing directions whereby the cables are moved in opposing directions thereby rotating the pulley within the receiver assembly, to move the bulkhead door.
