Oddziaływanie drgań pionowych na dziecko-niemowlę posadowione w foteliku podczas jazdy w samochodzie

Gromadowski T., Więckowski D.

Prace Naukowe Politechniki Warszawskiej. Transport

2014

z. 101

33--42

W pracy przedstawiono problematykę związaną z oddziaływaniem drgań pionowych na dziecko-niemowlę posadowione w foteliku podczas jazdy w samochodzie, w dwóch wariantach: fotelik zamocowany na fotelu przednim oraz fotelik umieszczony na kanapie tylnej. Przedstawiono zagadnienie związane z zagrożeniem drganiami mechanicznymi w środkach transportu drogowego. Podjęto temat oddziaływania drgań na dziecko-niemowlę. Przeprowadzono badania eksperymentalne drogowe z wykorzystaniem manekina NIEMOWLĘ (N). Podkreślono brak badań w tym zakresie. Na podstawie własnych badań eksperymentalnych wykonano analizę w dziedzinie czasu.

The elaborate described issue of vertical vibrations impact on baby sitting in a car seat while driving. It concerns two options: baby car seat fitted to the front seat and to the back seat. The matter concerns danger of mechanical vibrations in means of transportation. Raised the subject of vibrations impact on baby. Performed experimenta, road tests used manikin of a baby. The lack of tests concerning this matter is underlined. Basing on individual, experimental tests an analysis of time field has been conducted.

Frequency analysis of vertical vibrations acting on a baby transported in a child car seat

The biggest dangers that may result from human exposure to vibrations caused by vehicle movement occur in automotive transport [6]. The vibrations experienced during vehicle ride may cause a variety of pathological symptoms arising in people. The adverse health effects may also include reduced motion control, blurred vision, or impairment of the ability of free communication, memory processes, or perception [6]. The paper covers the impact of vertical vibrations on a baby riding in a safety seat in a car, with addressing in particular the dangers caused by mechanical vibrations to children in transport facilities. Two options were considered, with the safety seat being installed on either the front or rear car seat. Experimental road tests were carried out with using a dummy representing the baby. The lack of research work on this issue has been emphasised. For the sake of maximum safety, babies should be transported in safety seats. The type approval tests of child safety seats are chiefly focused on the evaluation of protection from harmful collision effects, according to UN ECE Regulation No. 44 [S13]. Regrettably, they do not include tests to determine the influence of vibrations, especially those occurring during “normal” ride, on the child’s body.
