Abstract

Car accidents are a major injury cause for children. The severity of the injuries can be significantly reduced by using safety seats. One type of safety seats is the Booster seat, which is used from a weight of 18 kilos to the height of 1.45 meters - the average height of 9 years of age for boys and girls in Israel. The booster makes the height adjustments between the child and the car seat belts which are designed for taller adults. Research shows that the booster seat is less used compared to the other safety seats.

Many children stop using boosters at a premature stage, before they reach the recommended height or age. As a result they are exposed to the "Seat Belt Syndrome", in which specific organs are injured during car crashes by the seat belt.

There have been many attempts to inform and educate the families regarding safety seats and boosters, but today there is no informative product which can function as a reminder for the time period in life when the booster is to be used.


The main objective of this paper is to propose a design for a new product to aid in the decision making on the use of boosters.


In order to achieve the objective, two focus groups have been conducted. One included 6 adults, and the other included 14 kindergarten children. Another method was a questionnaire which was distributed among 72 parents to 4-9 year old children. It had two main objectives: to show the knowledge of the parents regarding the use of boosters, and to show whether a tendency toward an informative product exists.

The results of the two focus groups show a use of target numbers on the product and both groups marked the products with graduations. The results from the questionnaires are consistent with earlier studies, and show that the percent of children who use boosters declines as the children are older. There was a confusion of when to terminate the use of boosters and on what grounds (weight or height). Most parents showed a positive tendency toward an informative product in their cars.

The design of the final product was a process, in which all the information which was gathered in the questionnaire and the focus groups was adapted into a coherent, user centered product which answers the needs of the target populations.
