The system, consisting of actuators (26, 28) for an adjustable seat back (18) and leg rest (20), linked to a transducer furnishing a crude value for current actuator positions, has a control unit (30) with calculators (80, 84) giving a corrected value, and memories (88) for the corrected and threshold values. The control unit also has an input (94) for reference positions, and a refined correction value setter (92). |
