This experimental research is aimed to evaluate the consequences of the slack offered by after- market web- ref- vld locking components ("comfort clips") on the performance of three- point seat belts. The laboratory results show a very bad performance of the devices under the test conditions, with a mean increase of 15- 20% for chest and 40% for pelvis displacement. The most worrying finding was the breakage of the belt, in 7 cases over 35; in other 3 cases, there was severe belt incision. All these laboratory data demonstrate danger in the use of these web- locking components.
