The purpose of this study is emphasized on searching for the ergonomic child safety seating design to reduce the neck injuries during forward car collision. The new designed prototype of ergonomic safety seat, featuring with two cushions under the seat, buffering device in the back-rest support and lowery placing the child restrain belt through the rear side of the seat, is suitable for the use...

There are many types of car suspensions control, H∞ control of vehicle suspension is studied in the literature for a brave time ago. We can define active suspensions as control systems incorporating a parallel spring and an electronically controlled damper. The contribution of this paper relies on H∞ control design to improve comfort and road holding of the car, and on control validation throug...

BACKGROUND One of the major causes of death among children younger than 15 years is vehicular injury. Car safety seats protect children in a crash if they are used correctly. The objective of this study was to assess the level of parental knowledge and their attitudes regarding car safety seats. METHODS The survey was conducted in May and June 2007 at Bakirkoy Dr. Sadi Konuk Research-Training...

One hundred ninety-five rear impacts with both front- and rear-seat occupants in the struck car, where at least one occupant sustained permanent disability, were selected for study. There was a significantly higher disability risk for the female rear-seat occupant compared with the male driver. Furthermore, a higher risk was found for female rear-seat occupants compared with female front-seat p...

Modern car seats are often equipped with adjustable lumbar supports for reducing fatigue and improving ride comfort in different driving conditions. Studies on the effect of lumbar support on seat dynamic performance and ride comfort are not often seen. This experimental study was designed to investigate how lumbar support affects static and dynamic characteristics of the driver seat of a sport...

The compulsory use of seat belts for drivers and front seat passengers was introduced to the United Kingdom in 1983. In 1991 legislation was extended to include rear seat adult passengers in cars where a seat belt was fitted. This protects rear seat passengers from ejection from the vehicle, and prevents them from becoming a hazardous projectile to front seat passengers in the event of a collis...

OBJECTIVE Many modern cars have seat belt reminders (SBRs) using loud and clear sound and light signals. These systems have developed over the last few years. This study investigates how these modern systems influence the seat belt use in real-life traffic in built-up areas in some European cities. METHODS The data were collected by field observations in major cities in six European countries...

Abstract—In this paper, passenger ride comfort issues are studied taking active quarter car model with three degrees of freedom. A hybrid fuzzy – PID controller with coupled rules (HFPIDCR) is designed for vibration control of passenger seat. Three different control strategies are considered. In first case, main suspension is controlled. In second case, passenger seat suspension is controlled. ...
