Abstract:
1. A helmet having a main body which defines a front opening, a shield which is vertically pivotally connected to the main body to open or close the front opening, and a locking mechanism for the shield to maintain a fully closed shield position by engaging a projection which extends from a side of the helmet main body opposite a lower end portion of the shield in the fully closed position, and a fitting portion formed on said lower end portion of the shield, wherein said fitting portion comprises an elongated hole, the projection extending into and being engaged by the fitting portion when the shield is in the fully closed position over the front opening of the main body, the locking mechanism including an operating element having a sloping surface and a pressing piece, the locking mechanism being rotatably connected to a side of said main body for rotation from a locking position wherein the pressing piece is located on a side of said shield opposite the main body, such that the lower end portion of the shield is located between the main body and the pressing piece, with the pressing piece preventing bending of said shield away from said main body and disengagement of said projection from within said fitting portion and thus opening of said shield relative to said main body, to an unlocking position wherein the pressing piece is moved away from said shield, such that said portion of said shield is no longer located between the main body and the pressing piece, and the sloping face of the operating element is moved between said shield and said main body to bend said shield away from said main body to disengage said projection from within said fitting portion and thus enable the rotation of said shield to an opening position relative to said main body.
