Post-collision examination requires verification of all seat belt assemblies starting from retractors and extending to buckles and front seat belt buckle support assemblies (slide bar) and shoulder belt height adjusters and child seat tether attachments and their attaching hardware. Technicians who show evidence of no damage and correct operation can maintain belt assemblies; otherwise, technicians should replace them. During the collision inspection, checks should include examination of belt assemblies which stayed unused; new installations must occur if damage or malfunctions are identified. Regular checks of seat belt assemblies need to happen because damage could occur from severe stress, but the proper working condition must always be confirmed. The inspection of attaching areas must be done before installing a new seat belt assembly to test for damage and distortion; if damage occurs, repair the sheet metal to its original condition. Follow manufacturer guidelines to set up new seat belts before proceeding with a Functional Test.
