Arrangement for determining position coordinates of pressure on surface evaluates sensor unit signals resulting from relative movement of stiff frame and stiff plate joined by flexurally weak zone

摘要

The arrangement has a flexurally stiff plate (16) movable relative to a flexurally stiff frame (18) and at least three sensor units between the frame and plate. The plate is joined to the frame by a defined, elastically deformable flexurally weak transition region/flexing zone (20) and the force action point is derived from the sensor unit signals resulting from the relative movement of the frame and plate.
