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:
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.

Opis:
The work presents the results of crash tests carried out with six electrical car models (from 2012-2013), with the weight of 1200-2300 kg (Smart Electric Driver, Mitsubishi IMiEV, Nissan Leaf, CODA, Ford Focus BEV, Tesla Model S). The results were published on the Internet by the National Highway Traffic Safety Administration (USA), and the tests involved a car travelling at the speed of 56 km/h, hitting frontally into a non-deformable (stiff) barrier, positioned perpendicularly to the car’s direction of movement. Particular attention was paid to the deformation of the car after hitting the barrier, so-called stiffness characteristics of the frontal crumple zone, and to the loads on the dummies placed at the driver’s and passenger’s seat (Hybrid III, a 50-centile man and a 5-centile woman). Results of the tests with electric cars were compared with the results of the tests with over a hundred of combustion engine cars with similar weight and type of car body (sedan, hatchback). The tests proved that, in the majority of electrical cars tested, the deformation of the frontal crumple zone after hitting an obstacle is larger than in case of similar cars with internal combustion engine. Because of that, the dynamic loads on the occupants of the vehicle tend to be smaller, as indicated by measured loads on the heads and chests of the dummies. The results may suggest that the frontal crumple zone may be better constructed in the case of electric cars, while the design possibilities regarding that area are limited in standard cars due to the combustion engine, which is not deformed during the accident, which makes it more difficult for the energy of the crash to dissipate.
