Samenvatting
The most recent official statistics worked out by the British Ministry of Transport show that about 13% of wounds, whether severe or slight, were caused by the glazing. Amongst points to be considered, can be mentioned the risk of cuts and also the importance and duration of stresses and decelerations applied to the human body. Beyond certain relatively low speeds, it is impossible, without considerable danger, to make the windscreen along absorb the whole kinetic energy of the passenger. It is explained how in case of impact, only a pop- out-windscreen is adapted to human tolerances of head and cervical column.
