An Exploratory Study of Integrating Booster Seat Design on Rear Seat Vehicle in Static Test

Abstract

Child Restraint System (CRS) is a safety seat created especially for child or small adult. The function of CRS is to protect or avoid child from any injury or death during vehicle crashes. This study presents a broad, comprehensive research effort that brings together industry and academic skill and uses numerous methodologies with countermeasures as the focus of applied research. The objectives of this study are to design mechanism for an integrated child seat booster for the rear seat and analyze the strength of the booster seat mechanism when loads applied on it. In order to get the seating reference point, 3D scanning process has been performed using car seat model from a toy car. A design of the booster seat mechanism is chosen for the reference based on the previous study. SolidWorks has been used in the designing and simulation of the static test process for the booster seat mechanism. The simulation has been performed to determine stress, strain and displacement of the integrated seat booster mechanism by applying different loads in static condition. The result from the simulation showed that when load D (37.08kg) was applied on the mechanism, it has the highest stress, strain and displacement which is 7689000N/m2, 2.22×10-5 and 1.74×10-2mm respectively. This is due to the fact that the more the force applied on the mechanism, the greater the stress, strain and displacement reacted on the booster seat mechanism. The success of this project will able the researcher and consumer to improve the safety of the childoccupant in the CRS during the event of crash.
