Abstract
Today, intelligent safety systems are installed in modern cars in view of minimising road hazards. An intelligent air bag system for example, comprised several subsystems that are integrated to include the weight sensor system, image sensor system, crash sensor system and tyre pressure monitoring system. These systems when poorly positioned into the car seat, will certainly affect comfort and reliability of the car seat. This research presents the design work on an intelligent car seat, which is equipped with a load cell type-sensory system. The load cells are used to detect the weight of a passenger for the deployment of an air bag system. The proposed design is validated against displacement and stress analysis using an 80 kg load to simulate the weight of a passenger. Results from the design validation indicated that the proposed configuration and material is appropriate for use in the intelligent car seat application.

Summary
Each year new and better automotive components are introduced by the automotive manufacturers in view of improving passengers safety and comfort as well as aesthetics. Developments related to automotive safety cost billions of dollars each year and that exclude casualties, death as well as its adverse effects to the environment[2,3]. The load cells are used for detecting the weight and position of the passenger for the deployment of an air bag in an ISS. The car seat is part of the improved features of the ISS for detecting road hazards. It combines several subsystems such as a weight sensor, image detector, collision system and a tyre pressure monitoring system. The air bag will be deployed under circumstances such as hazards occurring at a specific speed, the position of the driver to the air bag source and the presence of a driver in the vehicle
