The tragedy of electric vehicles without helmets occurs every day. The existing electric vehicles can only hang helmets on the handle or put them in the back box. Many people do not wear helmets because of laziness or negligence. I design an arm for the helmet through interesting design. The helmet can be attached to the leather cushion, so that the user must pick up the helmet to sit down during the process of using the helmet. The purpose of reminding the user to wear the helmet is achieved by this design. This is the concept work that I intend to participate in the design competition. The 3d printing model is being made. Thank you for your suggestions ~
