Increasing comfort and safety for occupants - seatbelts are the most important element of passive safety systems in modern motor vehicles and electronics as well as sensors are contributing to this by a great extent. Typical sub-assemblies include, for example, the Cherry activation units used in the seatbelt retractor. Like all other components for passive safety systems, they are protected against ingress of water, resistant to corrosion caused by salt spray and must satisfy the usal key requirements concerning reliability and endurance. In addition to integrating electromechanical sub-assemblies into passenger restraint systems, Cherry is becoming increasingly involved in development work with customers, focusing on the use of Hall-effect sensors for these applications.
