1. A device for simultaneously measuring relative movements and positions of parts of a human body comprising:
- at least two measuring sensors; and
attachment means for attaching said sensors to the parts of the body whose relative movements and positions are to be measured; and
at least two bars which are pivotally connected to each other and interconnect said means for attaching the sensors to the parts of the body, said bars forming a part of a pivotal parallelogram action linkage and the imaginary axes about which said movements are performed forming another part of said pivotal parallelogram action linkage;
said measuring sensors being arranged at vertices of said pivotal parallelogram action linkage;
said attachment means being for attaching a first one of said at least two measuring sensors to the head of the body for measuring the head'"'"'s rotation; and
for attaching a second one of said at least two measuring sensors to a shoulder of the body;
a first one of said bars thereby being pivotally connected with the measuring sensor on the head, said first bar at its opposite end being pivotally connected with a second one of said bars, and the measuring sensor on the shoulder being arranged at the vertex at the opposite end of said second bar remote from its pivotal connection with the first bar.

Abstract
Device for detection of relative motions or positions of one or more parts of the body, comprising at least two measuring sensors which are applied to the parts of the body whose motions or positions are to be measured. Signals from the sensors are transmitted to a signal processor for storing and/or analyzing. The measuring sensors are connected to the fulcrums of a parallelogram action linkage which is attached to the parts of the body whose relative movements or positions are to be detected. The imaginary axes about which some of the above-mentioned motions take place form a part of the parallelogram action linkage.
