- Abstract
- Masters Degree in Applied Science; Much has been written about seated working posture - particularly in the late 19th and early 20th centuries, and the furniture associated with achieving what is commonly referred to as the "German Square" postural geometry (after Mandal, 1974). The physical sciences aspects of chair, desk and associated furniture ancillary to the task required of the seated worker, have been described in the scientific literature and the standards and guideline publications of the authorities of many countries of the western world. The most important contribution of multi-adjustable furniture to the reduction of postural discomfort and musculo-skeletal complaints is recognised. As a result a variety of standards and guidelines concerning some of these aspects exists in countries such as the United Kingdom, Canada, United States of America, Germany, Australia and the Scandinavian countries. The International Organisation for Standardisation published document TC136/SC7 in 1978, consolidating such existing standards. Less emphasis has been placed on the interface of the information exchange and the comfort, performance and preferences of the seated worker; ie., the practically, the comfort and the intrinsic safety of the working posture prescribed by the model established by the many standards. Existing specifications and guidelines differ in their orientation towards operator performance and comfort of the operator, in as much as some purport to be "furniture standards", for example C.E.N, Comite European de Normalisation, Paris, 1980, while others purport to be "postural standards", for example, International Organisation for Standardisation document TC 136/SC7 (1978). The standards are uniform in matters of upright trunk and 90° upper and lower limb geometry, but are divided in the lineal dimensions applied to eye height above the floor, shoulder acromion to home row of keys (or pen-grip position of the dominant hand and fingers), and eye distance to copy.
