Definitions

  • the invention relates to a visor for a protective helmet, comprising two retaining arms and two bearing devices for the retaining arms, said bearing devices being attachable to a helmet shell of a helmet, for pivoting the visor between two end positions which correspond to an operating position, in which the visor is folded down and rests on a front edge of the helmet shell, and a parking position, in which the visor is folded up and disposed on the outer surface of the helmet shell.
  • a similar helmet known from document EP 1 841 338 B1 is preferably used as a police helmet.
  • the visor of the helmet When the visor of the helmet is folded up in the parking position, a substantial gap exists between the visor and the helmet outer face.
  • such a helmet When used in the forest area, such a helmet would have the disadvantage that branches could get caught between the visor and the helmet and pull the helmet from the user's head.
  • a protective helmet of the kind known from document DE 29 07 054 A1 when used in the forest area.
  • the visor assumes a parking position in which it has a particularly large distance from a shield-like front edge of the helmet and from the outer face of the helmet at a position which is further up relative to the edge, so that branches cannot get caught only between the visor and the outer face of the helmet shell, but also on the visor itself.
  • each bearing device is formed for being mounted to the helmet shell inside and each retaining arm extends from the visor to its free end connected to the bearing device substantially parallel to and with such a distance from the visor that a slot is formed between the retaining arm and the visor through which the helmet shell extends in the parking position.
  • the visor is disposed in close adjacency on the outer surface of the helmet shell in the parking position. The visor is guided by the retaining arms so that in the operating position it does hardly have any distance from the outer surface of the helmet with its upper edge. This visor does therefore not offer any opportunities for obstacles to get caught.
  • each of the bearing devices has a spring-biased locking element associated with it by means of which the visor is retained in a releasable manner by frictional force in the operating position and in the parking position.
  • the spring bias of the locking element causes the visor eventually to move into one of the two end positions on its own and with an increasing acceleration.
  • the visor or a frame of the visor hits the helmet in the end position, the visor may rebound and come to rest in a position that is not precisely the desired end position.
  • the impact on the helmet shell in the end position is always accompanied by generation of noise, which is usually perceived as annoying.
  • Known from DE 10 2009 012 450 A1 is a helmet having a visor equipped with a sealing lip which in the operating position rests against the helmet shell.
  • DE 36 07 483 A1 describes a protective helmet that comprises a folding part and a visor attached to the folding part.
  • the folding part In the operating position, the folding part cooperates with the helmet to have a sealing function.
  • the visor In the operating position, the visor cooperates with the folding part to have a sealing function.
  • this object is solved by providing the visor with a soft lip at least in an area in which the visor can be brought into close proximity or into touch with a helmet shell in the end positions.
  • the lip of the visor of the invention when its soft resilient lip hits the outer surface of the helmet shell in the end position corresponding to the parking position, the lip of the visor damps the momentum of motion so that a rebound is substantially prevented and the noise generated during the impact on the helmet shell is substantially damped.
  • the lip of the visor of the invention has the same effect when the visor in the end position corresponding to the operating position hits the protruding front edge of the helmet shell from above, wherein the sealing lip in this position additionally also provides a seal between the visor and the helmet shell so that raindrops pouring down on the outer surface of the helmet shell pour down aside via the visor toward the outside and thus do not enter the field of view of the person wearing the helmet.
  • the lip of the visor has the same sealing effect. Furthermore, in the parking position a view screen or a grid mesh in the frame of the visor provides a rain shield which does not allow raindrops to enter the field of view immediately.
  • the lip of the visor is a soft component, in contrast to a hard component formed by the view screen or the frame of the visor.
  • the soft component is resilient and prevents the hard component from rebounding from the desired end position.
  • the soft lip damps the closing momentum. This is significant in particular for a visor with a protective helmet where the visor always has a minimum distance from the outer surface of the helmet shell in both end positions and in the range between the two end positions.
  • the lip is formed and disposed on the visor such that in the operating position of the visor it can be placed onto a protruding front edge of the helmet shell. This does not only ensure good damping while assuming the end position corresponding to the operating position, but also ensures a particularly good seal between the visor and the helmet shell in this end position.
  • the lip is further formed and disposed on the visor so that it can be brought to rest against the outer surface of the helmet shell in the parking position. This close adjacency is beneficial for both the damping and the sealing function of the lip and ensures that the visor assumes and also retains each of the two desired end positions.
  • the lip is made of a soft resilient material which is shock absorbing as well as sealing, wherein in a further embodiment the material of the lip is preferably selectable among rubber, TPE, TPU, silicon rubber, PVC, or the like. Selection of a suitable material for the lip thus allows influencing its damping and sealing function.
  • the lip is attached to the visor or to a visor frame by frictional force.
  • the lip may have a suitable profile, for example, substantially a U-profile, allowing it to be easily plugged onto a corresponding ledge of the visor or a frame of the visor.
  • the lip is attached to the visor or to a visor frame by form fit and/or adhesion.
  • the connection by form fit can be achieved, for example, by providing the sealing lip at its free longitudinal edges with bulges which engage in a corresponding notch on the visor or on the visor frame in a manner similar to a bulge stripe engaging in a bulge rim.
  • a connection by adhesion can be achieved when establishing the connection of the lip with a visor or a visor frame, which is usually done during a spraying process, by welding or melting the lip with the material of the visor or the visor frame.
  • At least one of its bearing devices has a spring-biased end position lock associated with it which locks the support arm in each end position by frictional force and which accelerates the visor toward the other end position when pivot motion of the visor out of an end position is manually initiated, until the lip touches the helmet shell substantially without a rebound.
  • This end position lock which by itself is known, and the acceleration by the end position lock during the pivot motion between the two end positions, which by itself is known, are supplemented in accordance with the invention by the damping and sealing function of the lip, which facilitates assuming and retaining each end position.
  • the visor is combined with a protective helmet.
  • a protective helmet in which the visor is moved into the one or the other end position by hand
  • the visor of the invention has a particularly advantageous effect in the combination according to the invention if it is moved between its two end positions under spring bias, because it is capable of preventing a rebound by damping the momentum of motion when reaching the end of the pivot motion and, simultaneously, of damping generation of noise and, in addition, of having a sealing function.
  • FIG. 1 shows a side view of a visor of the invention on a protective helmet, in particular for forest workers, wherein the visor is shown folded up in a parking position,
  • FIG. 2 shows the protective helmet in the same side view as in FIG. 1 , wherein the visor is folded down in an operating position and wherein the protective helmet additionally carries a hearing protection not shown in FIG. 1 ,
  • FIG. 3 shows a top view of a front half of the protective helmet of FIG. 2 .
  • FIG. 4 shows the visor and a front part of the protective helmet as a detail in a sectional view
  • FIG. 5 shows a part of the detail of FIG. 4 on a greater scale
