Development and Evaluation of a Semi-Reclining Driver's Seat for the XM1 Tank 770250

The concept of a semi-reclining driver's seat for an advanced tank is based primarily on the need to provide a low tank silhouette in order to decrease the probability of enemy detection, and to present as small a target as possible. An initial seat field test was performed with four Army and nine Chrysler tank drivers. The test data indicated that the seat configuration provided a satisfactory compromise between silhouette and driver comfort. A supplementary laboratory experiment indicated improvement in comfort-discomfort ratings and favorable reactions to the overall driver's station as a function of increased legroom. Rigorous operational evaluations using experienced Army armor personnel reaffirmed the validity of the seat concept.
