摘要：

Knowledge of the interaction of forces between persons and the bed in which they lie or the seat on which they are sitting, provides an insight into the loading of their muscles, bones and soft tissue. To determine the total forces on the body-supporting surfaces (backrest, seat pan, foot rest) resolved in components perpendicular and parallel to these surfaces a new instrument has been developed, with which the forces perpendicular and parallel to three different freely adjustable body-supporting surfaces can be registered. During the first measurements the forces on a bed were measured when a person sits in a bed with the backrest at an angle of 45-degrees to the horizontal and the mattress horizontal. The measurements on a healthy population (mean mass = 77 kg, SD = 11 kg) showed an accuracy of +/- 10 N. In this position the mean shear force on the seat pan was 97 N.
