A helmet is used to protect the head of motorcycle rider especially when an accident happens by absorbing the impact/crash load. In Indonesia, wearing a helmet when riding a motorcycle is obligated by the constitution. Hence, in line with the quick growth of online motorbike and taxi service, carrying a personal helmet has become a common need. Yet, it becomes troublesome to carry and store the helmet due to its big size. This paper introduces a primary design idea of a foldable helmet for motorcycle rider by fulfilling the safety standard of SNI (Indonesian National Standard). The proposed helmet uses hinge components that allow the folding mechanism. Strength analysis of the hinge-pin lock system is discussed in this paper. From the result, it was confirmed that the foldable helmet could withstand a loading requirement of 3000 N at the joint system (hinge) as required by SNI. The proposed folding mechanism can reduce a helmet volume up to 50% smaller than the non-foldable one. Furthermore, this study is expected to give contribution to the engineering product design.
