An impact test stand for vehicle components, such as interior parts, operating parts and components of an occupant restraint system includes a stationary frame and an impact body. The impact body is mounted on a carriage. The carriage is guided by a guide track and driven by a linear drive. By accelerating the carriage, the impact body is driven against the component to be tested.

Impact test stand for vehicle components

A device for testing vehicle occupant restraint systems for a side impact, with a target carriage ( ) which is provided with a structure ( ) in which there are mounted a seat ( ) for a test dummy ( ), an imitation ( ) of the lower region of a vehicle side structure and the side impact restraint system ( ) to be tested, and with an impact carriage ( ) which is provided with a pushing surface ( ) associated with the imitation ( ) of the lower region of the vehicle side structure, the impact carriage ( ) and the target carriage ( ) being movable relative to each other such that an impact of the pushing surface ( ) and the imitation ( ) of the lower region of the vehicle side structure onto each other can be brought about at a predetermined speed, is characterized in that the structure ( ) is additionally provided with at least one imitation ( ) of the upper region of a vehicle side structure and that the impact carriage ( ) is provided with an upper pushing surface ( ) arranged above the lower pushing surface ( ).

Device for carrying out side impact tests on motor vehicle passenger restraint systems

A force limiter for vehicle safety belt systems which is inserted in the force flow path of the safety belt system by means of two fittings (26, 32), the distance between the fittings (26, 32) being able to be increased with a conversion of energy. In the context of such a force limiter the characteristic of the tensile force effective between the two fittings is to be rendered adjustable along the deformation displacement over a wide range. This is achieved since a first one (26) of such fittings is fixedly connected with the metal frame (20) having a deflection pin (22) arranged therein and a second one (32) of the fittings is fixedly connected with a first end of a metal strip (30), which is adapted to be drawn about the pin (22) along a positively set path. Owing to such configuration it is possible for the characteristic of the force limiter to be selected by the designer within a wide range independently of the threshold value as from which the force limiter takes effect.
