Seat belt assemblies together with their attaching hardware need assessment following any collision including retractors, buckles, the belt tension sensor (BTS) if present and front seat belt buckle support assemblies (slide bar) if present, seat belt shoulder belt height adjusters if present, child seat tether bracket assemblies and the automatic locking retractor (ALR) feature for child seats in passenger seating positions. A new seat belt assembly requires installation when any operational or damaged assembly fails the Functional Tests or shows incorrect operation. Seat belt assemblies along with their attaching hardware should not be installed unless the sheet metal maintaining structural integrity gets restored to its original state post any damage to the attaching areas because such neglect increases crash-activated injury risks. Installations of completely new seat belt systems that contain retractors and buckles and height adjusters become essential after front pretensioner deployment occurs. A scheduled check of seat belt assemblies must happen to make sure the components stay unharmed and function correctly following severe stress events. The installation of new seat belts must start with an examination of their attaching points for damage or shape distortions before sheet metal repair and restoration to original form and structure occurs. Installations should follow restoration and then perform the Functional Test.
