Abstract
The Mercedes- Benz passive restraint system consists of air bags deployed by means of solid propellant gas generators and kneebolsters. The sensor is designed to detect low and high impact severity levels. To balance the specific limitations of belt or air bag performance, combined systems have been studied, such as an air bag/ kneebolster system with supplementary belt or modern lap/ shoulder belt systems, supplemented by an air bag in the steering wheel and a pretensioner for the passenger belt, both of which are designed to prevent head/ face impact.
