Chapter 14 Anthropometry and biomechanics HFDS 2003 (amended Oct 2009)• 14.6.6 Wheelchair dimensions. Designers and human factorsspecialists shall use the data in Exhibit 14.6.6 for designproblems involving wheelchair users. This Exhibit presentswheelchair dimension data. [Source: UFAS, 1988]Exhibit 14.6.6 Wheelchair dimensions.The height of the handle is at 36 inches (915 mm). The armrest is 30 inches (760 mm) high. Eyelevel is between 43 and 51 inches (1090-1295 mm). The lap is at 27 inches (685 mm). The seat isat 19 inches (485 mm). The toe is at 8 inches (205 mm). The width of a wheelchair measuredfrom the outer edges of the back wheels is 26 inches (660 mm); the length is 42 inches (1065mm); the width measured from the outer edges of the footrests is 18 inches (455 mm). The toesextend 6 inches (150 mm) beyond the edge of the footrests.Note: Footrests may extend further for very large people.14-54
HFDS 2003 (amended Oct 2009)Chapter 14 Anthropometry and biomechanicsGlossaryAbduction - Movement away from the midline of the body.Acromion - The point of the shoulder.Adduction - Movement toward the midline.Anthropometry - The scientific measurement and collection of data about human physicalcharacteristics and the application (engineering anthropometry) of these data in the design andevaluation of systems, equipment, manufactured products, human-made environments, andfacilities.Bideltoid breadth - The maximum horizontal distance between the lateral margins of theupper arms on the deltoid muscles.Biomechanics - Describes the mechanical characteristics of biological systems, in this casethe human body, in terms of physical measures and mechanical models.Circumduction - A continuous circular movement of a limb.Correlation coefficient or "r" value - Describes the degree to which two variables varytogether (positive correlation) or vary inversely (negative correlation). The correlationcoefficient (r), has a range of values from +1.0 (perfect positive correlation) through -1.0(perfect negative correlation). Multiple correlation involves the predictable relationship oftwo or more variables with another criterion variable (such as a composite measurementvalue).Crinion - The midpoint of the hairline.Depression - The lowering of a body member from its normal position.Design limits approach - A method of applying population or sample statistics and dataabout human physical characteristics to a design so that a desired portion of the userpopulation is accommodated by the design. The range of users accommodated is a function oflimits used in setting the population portion.Distal - Away from the trunk (torso).Dynamic strength - A force exerted by limbs moving in a smooth manner over time, such aswhile lifting an object.Ectocanthus - The outside corner of the right eye formed by the meeting of the upper andlower eyelids. (Plural of ectocanthus is ectocanthi).Elevation - The raising of a body member from a normal position.14-55
