Definitions

  • the invention relates to a protective helmet with a visor that can be swung up and down on both sides of the helmet.
  • Protective helmets of this type are widely known.
  • the visor and protective helmet are connected by coaxial swivel joints, which allow the visor to rotate about a fixed axis of rotation for pivoting up and down.
  • the visor up and down all its points move in a circular arc around the axis of rotation, and a closer adjustment of the visor in its various pivot positions to the contour of the protective helmet leaves much to be desired, the more the helmet contour deviates from this circular arc.
  • the invention has for its object to provide a protective helmet of the type mentioned in such a way that the various visor positions can be more freely adapted in relation to the helmet and the helmet shape, even if the helmet shape deviates more from circular arc contours in the pivoting direction of the visor.
  • the visor and the protective helmet are connected on both sides of the helmet by a guiding device in which the visor is also guided so as to be displaceable relative to the helmet in a forced coupling with the pivoting movement.
  • the visor shift is preferably directed backwards in the one swiveling direction of the visor on the helmet and forwards in the other swiveling direction, in particular the rearward displacement of the visor with a swiveling-up movement, the front forward shift can be coupled with its pivoting movement.
  • the forward and backward directions are related to the direction of view of the helmet wearer.
  • the progress achieved by the invention consists essentially in the fact that a translational movement is superimposed on the pure rotary movement of the visor, so when the visor is pivoted up and down the axis of rotation is shifted parallel to itself, the direction and path of this shift depending on the pivoting movement can be largely arbitrarily chosen by suitable design of the guide devices.
  • the movement path of the visor can be adapted very effectively to the helmet contour, so that, for example, the opened visor closer to the Helmet shell than in the known protective helmets, or with the visor folded down, a larger distance from the face of the helmet wearer or from the edge of the helmet shell that limits the face opening of the helmet is obtained, which can be important for the rear ventilation of the folded-down visor.
  • each guiding device consists of two guides which, in the projection parallel to the axis of the pivoting movement of the visor, are designed as linear guides each consisting of two associated guide partners, one of which is firmly attached to the protective helmet, the other is firmly arranged on the visor that both linear guides also at least over part of their guide paths, again in the axis of the pivoting movement seen the parallel projection of the visor, inclined to each other, i.e.
  • linear guides enable wide variations in the movement path of the visor with respect to the helmet shell of the protective helmet by changing the angles mentioned, the length of the guide paths and the distance between the corresponding guide partners of both linear guides in a very simple manner.
  • the linear guides can be curved, as long as self-locking is only avoided. The simplest and therefore the most practical are the linear guides.
  • the arrangement is usually best made such that the linear guides each consist of a guide finger as the one guide partner and a guide track guiding the guide finger as the other guide partner.
  • the easiest way is to form the guide finger as a pin, the guide track as a guide slot receiving the pin or as a guide groove.
  • the pin itself can be rotatably mounted about the pin axis or a guide roller can be rotatably mounted on the pin.
  • a preferred embodiment is characterized in that the guiding fingers are arranged on the visor, the guideways on the protective helmet, and that with each guiding device one of the two guideways extends in the direction of the visor displacement, which means that the size of the visor displacement is predetermined the length of the guideways becomes shortest with both linear guides.
  • the protective helmet on the inside of its helmet shell has ear cups which have a wall part containing the guideways, to which the visor lies with a side part, which the carries outward-pointing guide fingers.
  • the ear cups are then expediently releasably attached to the helmet shell and designed as a carrier or holder not only for the visor but also for the helmet interior.
  • the guide devices can also be provided on the outside of the protective helmet.
  • the arrangement is best made such that the guide fingers on the outside of the helmet shell protrude outwards and the guideways are arranged on the side parts of the visor, the visor overlapping the outside of the helmet shell.
  • the helmet shell is designated 1, a cheek pad provided on the inside of the helmet shell with 2.
  • two holes 3 are located on both sides just above the cheek pad 2, through which screws and nuts 4 each two ear cups 5 can be screwed on as part of the interior in the Generalfig. c) are shown.
  • These earcups 5 have spacers 6 for connection to the helmet shell 1, so that both earcups 5 in the state installed in the helmet shell 1 are mutually parallel guide surfaces 7 for the one in the partial figure.
  • b) Form the visor 8 shown.
  • the visor 8 has a transparent disk 8.1, which is contained in a visor frame 8.2, which is guided with its frame ends 8.3 projecting on both sides beyond the edge of the visor disk 8.1 on the ear cups 5 in a manner to be described in more detail.
  • the ear cups 5 are carriers or holders not only of the visor 8, but also of the other parts of the interior, namely the inner cap 9, a neck strap 10 and a chin strap 11, which has a plug lock 12 with a tongue shown at 13 for opening and closing and is designed as a fork belt, the front fork part 13.1 on the auricle 5 and whose rear fork part 13.2 can be attached to the neck strap 10.
  • the ear cups 5 each have two guide slots 14.1, 14.2 running at an angle to one another and the visor 8 is provided at each end of its frame 8.2 with two guide pins 15, one of which on each helmet side has one guide pin in one of the two guide slots and the other guide pin reaches into the other guide slot from the inside out.
  • the guide pins 15 protrude slightly outwards from the guide slots 14.1, 14.2 and there, not shown in the drawing, overlap the edges of the guide slots, which secure the guide pins in the guide slots.
  • the visor 8 and the helmet shell are connected on both sides of the helmet by a guide device, which in turn consists of two guides, which are in the projection parallel to the axis of the pivoting movement of the visor, i.e.
  • linear guides namely straight guides
  • these guide partners are, without exception, designed as a guide pin 15 on the one hand and a guide slot 14.1 or 14.2 receiving the pin on the other hand.
  • Both linear guides are inclined to each other over the entire length of their straight guide path. Their guiding directions therefore enclose an angle 16 with one another, this angle 16 must have at least one size that excludes the self-locking of both linear guides.
  • the guide partners 14, 15 stand in both linear guides at one end of the guide path, in the folded end position of the visor 8 shown in dashed lines at the other end of the guide path.
  • the guide pins 15 can be rotatably mounted about the pin axis.
  • FIG. 1 and 2 which show protective helmets with guide devices arranged on the inside of the helmet, the guide pins 15 on side parts 8 'of the visor, the guide slots 14.1, 14.2 on the protective helmet, in particular in FIG. 1, are arranged on the ear cups 5.
  • the guide pins 15 on side parts 8 'of the visor, the guide slots 14.1, 14.2 on the protective helmet, in particular in FIG. 1 are arranged on the ear cups 5.
  • one of the two guide slots in FIG. 1 the upper 14.2, in FIG. 2 the lower guide slot 14.1, extends in the direction of the visor displacement, that is to say the displacement of the axis of rotation. If the visor in FIG. 2 is moved from the opened position into the folded-down position shown in dashed lines, the guide pins 15 seated on the visor 8 run in the guide slots 14.1, 14.2 into the position shown in dashed lines.
  • the trajectory curve b 'in Fig. 2 describes the path of the sighting point B when the visor 8 would perform a purely rotating movement about the axis D in the position shown in dashed lines.
  • the guide devices provide the visor 8 with a forward displacement in the described movement, so that point B moves along curve b "into point B". This results in a forward displacement E between the two folded visor positions, which is equal to the length of the un tere guide slot 14.1.
  • the guide pins 15 are at the rear, in the folded position at the front end of the guide slots 14.1, 14.2.
  • the guide devices are arranged on the outside of the protective helmet.
  • the guide pins 15 on the outside of the helmet shell 1 projecting outwards, so they keep their position unchanged during the visor movement.
  • the guide slots 14.1, 14.2 are now arranged on the side parts 8 'of the visor 8, the visor 8 overlap the helmet shell 1 with these side parts 8' so that the guide pins 15 projecting outward from the helmet shell 1 into the guide slots 14.1, 14.2 can intervene.
  • the guide slots 14.1, 14.2 move along the fixed guide pin 15 in the positions shown in dashed lines at 14 '.
  • the guide pins 15 are at the front end of the guide slots 14, in the folded position at the rear end.
  • the extent of the forward displacement of the visor 8 in the folded-down position is determined by the length of the lower guide slot 14.1.
