Development of seating accommodation models for soldiers in vehicles

Area of Science:

• Human Factors Engineering
• Ergonomics
• Military Vehicle Design

Background:

• Optimizing driver seating is crucial for military vehicle operational effectiveness and safety.
• Previous seating accommodation models did not account for personal protective equipment (PPE) and body-borne gear worn by soldiers.
• Tactical vehicle design requires specific consideration of driver anthropometry and posture.

Purpose of the Study:

• To develop statistical models for predicting driver-selected seating positions in military vehicles.
• To create the first driver accommodation models that incorporate the effects of body armor and body-borne gear.
• To provide a foundation for designing more accommodating and ergonomic seating in tactical vehicles.

Main Methods:

• Analysis of soldier driving postures and seating positions from a large-scale laboratory study.
• Application of regression techniques to develop statistical accommodation models.
• Focus on driver positions with fixed heel points and variable steering wheel locations in tactical vehicles.

Main Results:

• Developed predictive models for driver seating accommodation based on population anthropometry and vehicle layout.
• Successfully integrated the impact of body armor and body-borne gear into seating accommodation predictions.
• Established novel models applicable to typical tactical vehicle designs.

Conclusions:

• The developed models offer significant benefits for the design of military vehicles.
• The methodology can be extended to other driving environments where protective equipment influences seating posture, such as law enforcement and firefighting vehicles.
• These findings represent a significant advancement in understanding and modeling driver accommodation in demanding operational contexts.
