Abstract : Helmet visor support apparatus is provided which can move the visor between a raised and a lowered position by the operation of one hand. The apparatus comprises a visor support arm pivotally attached to the helmet at a pivot point for moving the visor between the raised and lowered positions. A positioning means is attached to the helmet at the pivot point and has at least two bores corresponding to the raised and lowered visor positions. A locking pin retractably engages either one of the bores in the positioning means to lock the visor support arm in position. A spring coiled around the locking pin normally biases the locking pin in engagement with one of the bores. A manually activatable retracting means is attached to the locking pin for retracting the locking pin from the one of the bores upon being manually activated, thereby allowing the visor support arm to pivot. The retracting means is supported on the visor support arm between the two ends thereof and is positioned to be activated by manual movement away from the pivot point and towards the visor.
