Design Guide for Saddle Seating on Small High-Speed Craft

摘要

This design guide gives recommendations for the design of saddle-type seatingfitted in small high-speed craft. Recommendations are made for the dimensions, angles, contouring and padding of the seat pan and backrest. Body depth and lateral space clearances are also considered, as are the positioning and dimensions of toe-straps and hand-holds. The recommendations are based on the principle of matching seat dimensions to the relevant dimensions of the user population so as to minimize passenger discomfort and reduce fatigue caused by inappropriate sitting postures. The dimensions suggested are appropriate for British males aged between 19 and 45 years. The anthropometric dimensions and population percentile values used in recommending each dimension are also specified so that the given values can be replaced by those appropriate to a different user population. The rationale behind the suggested dimensions and the consequences of deviating from the recommended values are specified.
