Anthropometric Design Considerations for Truck Cab Driver's Seat
The provided figures and dimensions illustrate the importance of considering anthropometric data when designing truck cab driver's seats. Each dimension of the cab corresponds to a specific body dimension, highlighting the need to utilize either the 5th or 95th percentile anthropometric data for optimal design. Proper alignment of cab dimensions with body dimensions ensures comfort and safety for drivers of varying sizes.

Example 1 The following figure shows a view of the driver's seat of a truck cab, with dimensions corresponding to the letters below. The figure of the person indicate 36 different body dimensions. For each cab dimension below, indicate (first column) the important (limiting) body dimension number, and (second column) whether a 5th or 95th percentile anthropometric dimension should be used.
