The micro-adjuster control system, which was built directly into the lumbar support part of an automobile seat, was provided by Schukra of North America. For this thesis, three factors at two levels were studied. They were: cycle (2 min and 5 min), wait (15 sec and 30 sec), and pulse (0.8 sec and 1.1 sec). Based on this arrangement, a 2$\sp3$ full factorial, repeated measures design was employed. In each condition, subjects were required to sit on the experimental automobile seat for two hours. Ten relatively healthy subjects (five males and five females), ranging in age from 19 to 27 years, agreed to participate in this study. Data were obtained using electromyography (EMG). The response variable was the change in root mean squared ($\Delta$RMS) values. As a supplement, two questionnaires were developed specifically for this study. The purpose of this thesis was to determine the most optimal combination of cycle, wait, and pulse. (Abstract shortened by UMI.)Dept. of Industrial and Manufacturing Systems Engineering.
