The effects of pelvic belt anchoring location on wheelchair seating system loads in frontal impact motor vehicle crashes
Determining worst-case wheelchair seating system loading conditions in frontal impact crash tests is necessary to help develop a RESNA standard that evaluates seating systems used as seats for motor vehicle travel. Eleven sled impact tests were conducted to determine the effect of pelvic belt...
Force-exertion postures with external bracing in industrial tasks: data from an automotive assembly plant
During one-handed tasks, individua ls will often support their body mass using the contralateral hand or other body region. It is hypothesized that bracing postures are adopted to reduce and/or change the tasks demands, allowing the individual to assume a more optimal posture or reduce spinal...
Modeling variability in torso shape for chair and seat design
Anthropometric data are widely used in the design of chairs, seats, and other furniture intended for seated use. These data are valuable for determining the overall height, width, and depth of a chair, but contain little information about body shape that can be used to choose appropriate contours...
New definition of legibility index to examine off-axis viewing of text and graphics
Reading text and graphics is a common issue in lighting design and practice. Legibility of text and graphics is often measured using the Legibility Index, conventionally defined as the distance at which material can be read with perfect accuracy (the legibility distance) divided by the character...
Characterization of knee impacts in frontal crashes
Analyses were performed to quantify the conditions under which the knee is loaded in frontal motorvehicle crashes and to thereby provide insight on the test conditions that should be used in future studies of the tolerance of the knee to loading of its anterior surface. These analyses estimated...
Predicting force-exertion postures from task variables
Accurate representation of working postures is critical for ergonomic assessments with digital human models because posture has a dominant effect on analysis outcomes. Most current digital human modeling tools require manual manipulation of the digital human to simulate force-exertion postures or...
Crashworthiness of forward-facing wheelchairs under rear impact conditions
Current voluntary wheelchair standards address crashworthiness for wheelchairs used as seats in motor vehicles under frontal impact conditions. A new standards development effort addresses the crash performance of forward-facing wheelchairs in a moderate-severity, rear-impact crash. Dynamic sled...
