Mercedes Benz C-Class. Front Emergency Tensioning Retractors

The emergency tensioning retractor in the W204 is a new design of toothed rack retractor tensioner. The functioning principle is based on the fact that an integrated toothed rack, which is fired pyrotechnically, unwinds via a cogwheel connected to the seat belt retractor and thus initiates the belt tensioning.
