Abstract
A sensor for measuring the deflection of a thorax of an anthropomorphic dummy includes a base for mounting on a thoracic spine assembly, a tape drum rotatably mounted on the base, at least a pair of spring tapes each having one end connected to the base and an opposite end attached to the tape drum, the spring tapes biasing the tape drum for rotation in a predetermined direction, and a displacement tape having one end attached to and being wound about the tape drum in a direction opposite the predetermined direction and having an opposite end for attachment to a rib set of the dummy. The sensors are mounted in four pairs on the spine assembly and the opposite end of the displacement tapes of each pair are attached together to a different point on the rib set. The sensors in each pair are spaced apart a first predetermined distance along a Y axis and a ninth sensor is spaced a second predetermined distance from one of the other sensors along a Z axis. Deflection of the rib set toward the thoracic spine assembly will cause the tape drums to rotate in the predetermined direction to wind up the displacement tapes to indicate the deflection of the rib set through triangulation.
