Opis:: The analysis carried out by the authors indicates high threat to the rear seat passengers in passenger cars during a road accident. Vehicle designers indicate potential threats for passengers when they take a position in a car which is unexpected by a manufacturer of passive protection systems. Based on that, the tests were prepared in order to consider several different positions of a rear seat passenger. In particular, attention was paid to a threat to passengers when they take a position unexpected by a manufacturer of the passive protection systems in a car. Indicating and justifying a need to adjust the operation of the individual protection means to a passenger anatomy and current passenger position in a car in order to optimize his protection makes an important aim of these tests. This paper presents the results of the tests performed with a Hybrid III dummy, size M50, placed in three different positions in the back seat of a car. During each test, a series of physical values were measured and the motion of a dummy against the car body and the car interior components were filmed. The effects resulting from a change of a passenger’s position, observed on the courses of dynamic loads occurring during an accident, were analysed. Despite of small changes to a passenger’s position, their significant influence on the dummy movement during a frontal collision of a car and an obstacle was observed.

Opis:: Results of investigations of the dynamic loads acting on the occupants of backseats in a passenger car during a frontal collision and an analysis of such loads have been presented. The analysis was based on results of experimental tests carried out on a crash-test stand at the Automotive Industry Institute (PIMOT). It was focused on the influence of the pre-tightening of seat belts on the state of loading of test dummies representing a 50 centile male (M50) and a child aged about 10 years. The child dummy was placed in a child safety seat (which included both a seat cushion and a backrest), designed for children with a mass of 15 to 36 kg. The dummies were restrained with the use of standard seat belts. The quantities taken into consideration included head and thorax accelerations measured for both dummies and, for the M50 dummy, forces and moments acting on the neck, thoracic deflection, and axial forces in the thighs. In the analysis, results of three crash tests with different seat belt pre-tightening force values were taken into account. To estimate the risk of injury, indicators of biomechanical immunity of the human body to the effects of impact loads were used. Conclusions drawn from a frame-by-frame analysis of films recorded by means of high-speed cameras were also taken into consideration at this work. The benefits of adequate pre-tightening of seat belts by the user, especially by seat belt pretensioners, were confirmed. In the case of seat belts with pretensioners, the risk of severe injury to an adult passenger (AIS4+) was estimated at 18%, i.e. about a half of that incurred when seat belts without pretensioners are used. For a child, the pretensioners were found to reduce this risk to 9%, i.e. to about one-third.
W pracy przedstawiono wyniki badań i analizę obciążeń dynamicznych, jakie działają na osoby na tylnych siedzeniach w samochodzie osobowym, podczas zderzenia czołowego. Analiza została przeprowadzona na podstawie rezultatów badań eksperymentalnych, przeprowadzonych na stanowisku zderzeniowym w Przemysłowym Instytucie Motoryzacji. Uwagę skupiono na wpływie wstępnego napięcia pasów na stan obciążenia manekina reprezentującego 50-centylowego mężczyznę (M50) oraz manekina dziecka w wieku około 10 lat. Manekin dziecka siedział w foteliku samochodowym (podstawka z oparciem), przystosowanym dla dzieci o masie 15÷36 kg. Manekiny przypięte były za pomocą standardowych pasów bezpieczeństwa. Rozważono przyspieszenie działające na głowę i klatkę piersiową obu manekinów oraz siły i momenty działające na szyję, ugięcie klatki piersiowej oraz siły osiowe w udach manekina M50. W analizie zostały wykorzystane wyniki trzech prób zderzeniowych, w których pasy bezpieczeństwa były wstępnie napięte siłami o różnych wartościach. Do oceny ryzyka obrażeń wykorzystano wskaźniki biomechanicznej odporności ciała człowieka na skutki obciążeń udarowych. Podczas analizy wykorzystano także wnioski z analizy poklatkowej filmów nagranych za pomocą kamer do zdjęć szybkich. Potwierdzono korzyści wynikające ze wstępnego napięcia pasów bezpieczeństwa przez użytkownika, a zwłaszcza przez napinacze. Oceniono, że po zastosowaniu napinacza ryzyko ciężkich obrażeń dorosłego pasażera (AIS4+) jest około dwa razy mniejsze (18 %) niż w samochodzie bez napinaczy. W przypadku dziecka jest to 9 %, czyli trzykrotnie mniej niż z pasami bez napinaczy.

Opis:: The dynamic loads acting on a human body during a road accident may cause bodily injuries. They are dependent not only on the car structure and applied means of individual protection but also on the anthropometric features of a human body and its location in car. The safety of the car occupants on the rear seats in the passenger cars has been treated as a secondary issue so far. The achieved stage of the structure of that equipment for the rear seat occupants makes an important confirmation of that state. Usually there is no adjustment of the seat belt fixing point position, seat belt pretensioners, seat adjustment. This paper considers the risk of injury for the front and rear seat passengers of the passenger cars on the basis of analysis of dynamic loads that can affect them during the road accident. The attention was paid to the adults and children aged about 10 years. The dynamic loads were analysed with making use of experimental results of frontal flat barrier impact. During the tests, the passengers are protected by typical passive safety systems on the front and the rear seats. In the evaluation used the criteria of the biomechanical human body resistance to the impact load effect. The attention is paid to relations between a seat occupied in a car and the probability of injuries. The analysis of the laboratory impact tests was preceded by the assessment of risk of injury of the front and rear seat passengers in the real road accidents, which has been prepared based on the literature data.
