ABSTRACT:
A test fixture operative to simulate seat belt assembly installations. An articulated arm assembly, comprising a primary arm and a secondary arm, has its primary arm lower end mounted by a dual pivot of a support base at the origin of X and Y axes of an X, Y and Z coordinate system. The anchor position of the seat belt retractor is adapted to be releasably fixed on the support base relative to the X and Y axes. The seat belt webbing pillar turning loop is pivotally and linearly adjustably supported on the secondary arm. A motorized load transducer, located on the primary arm, extracts the seat belt webbing from its stowed position on the retractor providing measurements of the forces required to perform this action. The test fixture allows various changes in vehicle seat belt system components to be measured thereby readily determining the optimum installation geometries for a seat belt system that is comfortable and easy to use.
