The head impact test serves the manufacturer of steering wheels, seats, head-rests, instrument panels etc. and the costumers for the proof that the products fulfill the cossresponding regulations of the ECE-R 12.
A rigid examining head is accelerated with a mass of 6.8 kilograms and a diameter from 165 mm on a speed of at least 24.1 km/h.
The examining head shall feign the impact of the human head on the examinee during an accident. Measured over 3 ms, predefined in terms of as a permitted limiting value a middle delay of 80 g is.
For the production of the impact velocity the gravitational force is made use of, i.e. the examining head beats led out of a defined height linearly on the examinee. This test bed is realized by means of a 5 m high aluminium profile framework. In this the examining head which is put together on one over engine and sledge placing destitute of toothed belts becomes on the examining height driven and there fixed by the computer by means of an electromagnet automatically.
The examining head falls virtually friction freely at the triggering of the examination about a computer order on the examinee.
