Definitions

  • the invention relates to an integral helmet with a plastic helmet cap, at the front edge of the slip opening a chin spoiler part carrying a chin pad is articulated by means of a folding hinge and locked in the closed state.
  • the integral helmets which are primarily designed for motorcyclists, have a helmet cap that is provided with a continuous chin section below the visor opening and thus protect the chin area of the helmet wearer.
  • a spoiler part is usually attached below this chin area, which on the one hand prevents the wind from flowing directly from the neck area into the interior of the helmet, and on the other hand exerts a cushioning function for the chin.
  • Integral crash helmets of this type are usually held on the head of the helmet wearer with a chin strap which crosses the slip opening and should lie against the chin of the helmet wearer.
  • the chin strap usually consists of two ends that are connected with a snap lock. After the helmet has been pushed onto the head, the chin strap must be closed. Since the helmet wearer cannot see into the area of the chin strap, the chin strap only has to be closed using buttons. Closing the helmet is therefore cumbersome and time-consuming.
  • a helmet of the type mentioned at the outset has become known as the GPA helmet (DE-OS 28 47 933).
  • the chin spoiler part is designed as a plastic part that can be folded open around a horizontal hinge, the hinge sitting in the middle on the front of the helmet.
  • An identical hinge which is attached to the center of the back of the helmet, holds a corresponding neck spoiler part, so that the two spoiler parts can be folded away from the helmet cap to the front or back.
  • the helmet can be pulled onto the head of the helmet wearer.
  • the two spoiler parts are closed and, due to their shape, reduce the slip opening to such an extent that the helmet can no longer be detached from the head of the helmet wearer.
  • the helmet is fixed after being pushed onto the head of the helmet wearer by folding the two spoiler flaps, which replace a chin strap. Since the spoiler flaps are closed on a guided movement, the helmet wearer does not require any special attention, so that the fastening process for the helmet on the head of the helmet wearer is somewhat simplified.
  • the invention is based on the object of designing an integral helmet of the type mentioned at the outset in such a way that an awkward closing operation after putting on the helmet is avoided, and on the other hand no close closure of the helmet in the neck area is required.
  • a chin strap is attached to an end of the chin spoiler part which is folded away from the helmet in the open state of the chin spoiler part and which crosses the slip opening in the usual manner when the chin spoiler part is closed.
  • the integral helmet according to the invention also has a foldable chin spoiler part. However, this does not in itself serve to secure the helmet on the head of the helmet wearer, but primarily to close the chin strap, which is thus automatically applied when the chin spoiler part is closed. The cumbersome closing of the two ends of the chin strap is therefore replaced by the simple, guided closing movement of the chin spoiler part.
  • the chin strap can be adjustable in length in the usual way, so that a simple adaptation to different head lengths is possible. This can ensure that the helmet sits securely and free of symptoms even for different head lengths.
  • the lower edge of the insertion opening can be designed in the usual way so that no edge significantly reducing the insertion opening is required, which also constrains the head of the helmet wearer from below and furthermore makes ventilation of the helmet interior more difficult.
  • the folding hinge is approximately perpendicular to the plane formed by the edge of the slip opening in the front chin region of the helmet cap and is attached to one side of the helmet cap.
  • the chin strap is fastened to the free end of the chin spoiler part which can thus be pivoted approximately parallel to the edge of the slip opening, its other end being fastened to the chin spoiler part or to the helmet cap in the region of the folding hinge.
  • the chin spoiler part swings out of the side of the helmet cap.
  • This pivoting arrangement has the great advantage that the unfolded chin spoiler part does not interfere when putting on the helmet and does not make this putting on difficult.
  • the folding movement of the chin spoiler part about a horizontal hinge forward in the known helmet leads to a hindrance to putting on the helmet due to the ends of the chin spoiler part projecting downwards, ie against the chest of the helmet wearer.
  • the opening movement according to the invention is made even more advantageous if the folding hinge is provided with a lifting guide, by means of which the chin spoiler part is displaced downwards away from the slip opening during the opening process.
  • a lifting guide is known from general hinges. Guiding the chin spoiler part when opening it down the advantage that when closing the chin spoiler part the helmet is guided from below against the chin of the helmet wearer.
  • the preferred folding movement laterally out of the area of the helmet cap enables a further advantageous embodiment, in which the helmet cap has an outwardly open groove at the front edge of the slip opening and the foldable chin spoiler part has an inwardly open groove and the chin spoiler part thus has its groove when it is closed pushes on the groove of the helmet cap that both grooves interlock.
  • the chin spoiler part is connected extremely securely to the helmet cap and is optimally secured against opening in the event of a lively impact on the chin spoiler part.
  • the integral helmet according to the invention preferably has no foldable neck spoiler part. Rather, it is preferred if the home calotte has a recess for the chin spoiler part and the folding hinge is attached to an edge of the recess. In this case, the helmet cap itself forms the rim aligned with the chin spoiler part.
  • the integral helmet shown in the drawing consists of a hard, impact-resistant dome 1, which has an integrally molded chin part 3 running below a visor opening 2.
  • the visor opening 2 can be closed by a visor disk of a visor 4.
  • a hinge 5 is attached to one side of the chin part 3 and is characterized schematically in FIG. 1 by its axis.
  • the axis of the hinge 5 is approximately perpendicular to the plane formed by the front edge 6 of the slip opening of the helmet.
  • a hinged chin spoiler part 7 is fastened to the helmet cap 1 by the hinge 5.
  • the chin spoiler part 7 has an upper edge 8, the contour of which is practically identical to the contour of the front edge 6 of the slip opening, that is to say the slip opening in the chin region.
  • a web 9 extends flat inward from the upper edge 8 of the chin spoiler part 7.
  • a closure part 10 is fastened on the web 9 and cooperates with a latching mechanism for locking the chin spoiler part 7 in the closed state, which is attached to the chin part 3 and is not shown in the drawing.
  • the locking mechanism can be unlocked by a button 11 inserted into the chin spoiler part 3 and actuated from the outside, by pressing the button inwards against the pressure of the locking spring and thereby moving a pin of the locking mechanism out of a bore 12 in the closure part 10.
  • a fastening part 13 for a chin strap 14 is fastened on the web 9 at the free end of the chin spoiler part 7.
  • the fastening part 13 consists of an eyelet 15 through which the chin strap 14 is pulled.
  • the chin strap 14 is adjustable in length in the usual way.
  • the upper edge 8 of the chin spoiler part 7 has an inwardly open groove 16 which is delimited at the top by a web 17.
  • the front edge 6 is formed with a corresponding outwardly open groove 18, which in turn is delimited at the bottom by a web 19.
  • the two grooves 16, 18 mesh with one another by the web 17 engaging in the groove 18 and the web 19 in the groove 16. Since at least the last part of the closing movement of the chin spoiler part 7 takes place in the plane of the lower edge 6, the two grooves 16, 18 are pushed into one another without any problems.
  • the webs 17, 19 and the grooves 16, 18 are dimensioned with respect to one another such that the web 17 fits into the groove 18 and the web 19 into the groove 16.
  • a circumferentially toothed connection is created between the chin spoiler part 7 and the chin part 3 of the helmet cap 1, as is illustrated in a sectional illustration in FIG. 2. It is therefore practically impossible to tear off the closed chin spoiler part 7 from the chin part 3 of the helmet cap 1.
  • Figure 1 illustrates that the chin spoiler part 7 moves away from the lower edge 6 of the slip opening of the helmet when opening down. This movement could be brought about by an inclined hinge 5, but is preferably ensured by a lifting guide in the hinge 5.
  • the lifting guide can be designed so that no vertical movement of the chin spoiler part occurs at the beginning of the opening movement or at the end of the closing movement, so that the teeth of the grooves 16, 18 can be perfectly interlocked.
  • the hinge 5 sits at the front end of a recess at the lower edge of the helmet cap 1.
  • the recess for the chin spoiler part 7 has such a height that the lower edge of the chin spoiler part 7 just continues the lower edge of the helmet cap 1 outside the recess.
