Abstract

The car safety belt tensioning system comprises a vertical rack (34) whose teeth (36) cooperate with a pinion (32) on the end of a rod (30). This passes through a spool (28), to which the belt is fastened. An independent claim is included for a car safety belt fitted with the tensioning system.
