SITUATION
A major manufacturer of infant car seats required a more reliable method of holding the armrest onto the seat. Their former method was to use a standard screw to fasten the armrest in place. The movement of the armrest up and down would loosen the screw. They needed a method that would hold the armrest firmly in place, while still allowing it to rotate as designed.
SOLUTION
Through our ENGINOMICS ®, Driv-Lok Inc. identified a solution to the problem by using an engineered Ferrol Stud. Ferrols around the circumference of the pin are designed so the plastic flows over them when the pin is inserted. The ferrols then lock into the plastic, making removal of the pin virtually impossible. This allows the arm to rotate freely while maintaining the required tight fit.
