Continuous Loop Shoulder/Lap Belt Test

System with Movable Tongue and One Retractor

1. Driver will buckle up and proceed to a safe test area. If the RH passenger safety belt must be tested a passenger should be buckled into the RH seat. (The passenger belt may be tested utilizing a driver only, providing the driver has the ability to grasp the RH shoulder belt and extend it approximately (660 mm) 26 inches with no compromise to safe driving.) This method applies to the 8 km/h (5 MPH) test only.

NOTE: The RH shoulder belt is not extended fully to preclude the possibility of a false feeling (full extension vs. lockup).

2. After reaching a safe area to perform sudden stops, the driver will attain a speed of approximately 8 km/h (5 MPH). The driver should inform the passenger (if applicable) that he is preparing to make a severe brake application. At this time, both driver and rider should grasp their respective shoulder harness and prepare to lean slightly forward at the moment the brake application is made.
3. The driver will make a maximum brake application (approximately 9.7 m/sec sq [32 ft/sec sq]) without tire skid. (The maximum brake application should be on dry concrete or equivalent hard road surface, never on a wet or gravel road.) The driver and passenger should lean forward slightly into the shoulder harness. At this instant, the belts should "lockup" without webbing payout.
4. If there is a "lockup" of both shoulder straps, the seat belt assemblies are functioning properly. Should either or both retractors fail to "lock up" at the 8 km/h (5MPH) speed, the test should be repeated at a constant 24 km/h (15 MPH). (This test must be performed with a passenger if the RH belt is to be tested.)

WARNING: THE DRIVER AND PASSENGER SHOULD BE PREPARED TO BRACE THEMSELVES IN THE EVENT THE SAFETY BELT RETRACTOR DOES NOT LOCK.

5. If either or both shoulder belts do not lock up at the 24 km/h (15 MPH) test, the vehicle is to be returned for repair of the malfunctioning seat belts. Remove the retractor and rework the sheet metal in the retractor's mounting surface. Install the retractor assembly and re-test the safety belt assembly(s) as previously stated.

CAUTION: If the retractor of a new safety belt assembly has been bolted into a damaged or distorted mounting area, the new retractor could be warped and may not function. If this is the case, re-shape the sheet metal and install another new complete safety belt assembly.
