Definitions

  • the invention relates to a protective helmet, in particular a helmet, with a helmet cap with a visor opening and a transparent visor attached to the helmet cap by means of a control plate having at least two guide tracks for at least two bolts, the guide tracks causing the visor to move radially away from an edge of the visor opening enable when opening the visor from the closed position and at least one of the bolts can be acted upon by a spring force, and wherein the interaction of at least one bolt with its guideway results in at least one latching of the visor in an open position.
  • Protective helmets with eye protection in the form of a flip-up visor have been known and used for many years.
  • Protective helmets of the type concerned by the present invention are, in particular, full-face helmets, the helmet cap of which - possibly with a separate part - continues into the chin area of the helmet wearer, so that the visor opening is limited on all sides by the helmet cap.
  • Such helmets are used in particular as crash helmets for motorcyclists, car racing drivers and test drivers, as aviator helmets, etc.

  • the visor must have appropriate points of attack at the ends of the visor, which enables the visor to be advanced by the user, who regularly wears thick gloves.
  • the points of attack must also be aerodynamically compatible in order to avoid whistling noises from the points of attack in the wind. The operation of the visor for the purpose of advancing is therefore not very comfortable for the user.
  • the visor must have further points of attack for the flip-up movement.
  • dome-shaped visor causes, is caused by an essentially V-shaped spring, which has been used as a separate component in the arrangement of the control plate and visor. Accordingly, the visor must also axially against the force of the spring when fully closed
  • the spring used also causes the elastic pressure force for the realization of locking positions by the other bolt, which is in the segment-shaped recesses of its guideway
  • the known arrangement does not allow optimal handling of the visor, since a separate pressing process is required when closing.
  • it is relatively complicated to assemble by inserting the spring between a bolt and the control plate.
  • a protective helmet is known from EP 0 302 212, in which the visor, which can be swiveled up and down, is guided on a path through which the visor is swiveled upwards in order to adapt to the shape of the helmet cap during the swiveling movement.
  • the invention is therefore based on the problem of facilitating the handling of a protective helmet of the type mentioned at the outset without sacrificing the function of a visor and improving its structural design.
  • a protective helmet of the type mentioned at the outset is characterized in that the opening and closing movement of the visor is controlled exclusively by the bolts guided in the guideways of the control plate, that the movement carries out at least one of the bolts in its guideway there is a resilient counter pressure element with a defined frictional force and that the spring forces for realizing locking positions and the counter pressure element are provided exclusively by the shape of the control plate and the elasticity of the material of the control plate.

  • Advance of the visor is controlled only by guiding the bolts in their guideways when the user wants to swing the visor up to the opening.
  • the guideways carry out a translatory movement pulling the visor against the edge of the visor opening, as a result of which the visor can be closed tightly at the edge of the visor opening.
