Definitions

  • the invention relates to an integral safety helmet, in particular for motorcyclists according to the preamble of the main claim.
  • Such a protective helmet is known from DE-PS 28 46 636. It consists of a helmet shell on which a chin part is pivoted. When the safety helmet is closed, the helmet wearer folds down the chin part, which in this position is automatically locked to the helmet shell by a locking mechanism. If the helmet wearer wants to remove the protective helmet, he presses two push buttons on the side. You unlock the chin part. The helmet wearer can swing it up and remove the protective helmet.
  • the object of the invention is to develop such a known integral safety helmet so that the chin part can be unlocked and swiveled up in a simpler manner.
  • the helmet wearer can press this button with just one hand. Since the chin guard must first be pivoted upwards to remove the protective helmet, it is a further feature of the invention to adapt the actuation direction for the opening button to this pivoting movement. In this way, the helmet wearer swivels the chin guard upwards when the opening button is pressed.
  • the opening button is designed as an actuating lever which is arranged approximately vertically on the front of the chin guard. Its upper end section is mounted in an axis of rotation provided on the chin guard. The lower end section of the opening button has an easily accessible shape.
  • the opening button is designed as a two-armed lever which is mounted in the middle on the chin guard. To this way you get a combined push / pull button.
  • the lower lever arm can be seen as a pull button because it is gripped from behind and pulled forward.
  • the upper lever arm is the push button because it is pressed against the chin guard when pressed. This configuration of the opening button enables the helmet wearer to unlock the chin guard in two different ways.
  • the chin guard In the event of an impact, the chin guard should not be released automatically. It is therefore advisable to arrange the opening button sunk inside the chin guard.
  • the return of the opening button to the initial state, in which the chin bar is locked down with the helmet shell, is expediently carried out again by a compression spring which is arranged between the push button part or the upper lever arm and the wall of the chin part.
  • the opening button is connected to a locking mechanism via a cable.
  • the locking mechanism can be designed in different ways.
  • a snap spring engages in this locking bolt, which is in turn fixed on the chin bar and is actuated via the cable pull.
  • the type of activity can also be of various types.
  • a release lever is provided for this purpose, which is mounted within the side wall of the chin guard and against Presses spring force on the snap spring.
  • this release lever is also designed as a spring element and, as the only component, also takes on the function of the snap spring.
  • a motorcyclist 1 can be seen in FIG. 1, wearing an integral protective helmet 2 on his head.
  • the protective helmet 2 consists of a dome-shaped helmet shell 3 which surrounds the head of the motorcyclist 1.
  • the helmet shell 3 pivotably supports a chin guard 5 via swivel joints 4 on both sides (only one of these swivel joints is visible due to the type of representation).
  • the chin guard 5 is modeled on the lower jaw area of the motorcyclist and therefore overlaps this area approximately in the form of an elliptical half-shell. Its end sections 5a run at an angle upwards and are mounted in the axes of the rotary joints 4.
  • the motorcyclist is about to take off the helmet.
  • he has gripped an opening button 6 arranged on the front of the chin bar 5 with his thumb from below and presses it upwards.
  • the opening button 6 acts on a cable 7 a locking mechanism with which the chin bar 5 is locked down on the helmet shell 3.
  • the motorcyclist 1 on the opening button 6 the chin bar 5 swivels upward via the swivel joints 4 into the position shown in FIG.
  • the motorcyclist 1 can remove the helmet in this position.
  • FIG. 2 shows a lower section of the protective helmet 2 in an enlarged view.
  • the chin strap 5 shown in section is folded down and locked on the helmet shell 3.
  • a locking mechanism is provided on each side of the helmet, because of the type of illustration in FIG. 2 only one can be seen.
  • Each locking mechanism consists of a mushroom-shaped locking bolt 8 of the helmet shell 3.
  • the locking bolt 8 engages behind a snap spring 9, which is fixed at one end to the chin guard 5.
  • the chin bar 5 pivots on a bearing eye 5b on a release lever 10 which presses against the freely projecting section of the snap spring 8 and against its spring force.
  • One end of the cable 7 is attached to the release lever 10, the other end leads to the opening button 6.
  • the opening button 6 is on the front of the chin guard 5. It is elongated Lever executed and - seen from the front on the chin guard - is oriented approximately vertically on the chin guard 5. With its upper end it rests in a bearing eye 5c of the chin guard 5, so that it can be pivoted upward about an approximately horizontally extending axis - again seen from the front onto the chin guard. At its lower end section, the opening button 6 has an easily accessible shape 6a. At this point, the chin guard 5 also has a recess which allows the motorcyclist to grip the opening button 6 with his thumb and to push it forward. Finally, a fastening eye 6b protrudes from the opening button 6, on which the end of the cable 7 is suspended and from there leads to the locking mechanism, not shown, on the other side. The fastening eye 6b extends through an opening in the chin guard 5.
  • the motorcyclist (as also drawn in FIG. 1) only has to press his thumb against the section 6a of the opening button 6 from behind.
  • the opening button 6 rotates upward and pulls the obliquely set release lever 10 toward itself via the cable 7. This presses the snap spring against its spring force out of the locking bolt 8.
  • the chin guard 5 then swivels upward in the manner shown in FIG.
  • the spring force of the snap spring 9, on the other hand, causes the opening button 6 to be reset as soon as the motorcyclist releases it.
  • FIG. 3 again shows the lower section of the protective helmet 2.
  • the chin guard 5 is locked to the helmet shell 3 in the same way as in FIG.
  • the opening button 6 ' is designed as a two-armed lever with a lower lever arm 6c' and an upper lever arm 6d '. With its central section 6e ', it is pivotably mounted on a bearing eye 5c of the chin guard 5.
  • the swivel axis again runs horizontally when viewed from the front of the helmet, while the opening button 6 is oriented approximately vertically on the chin part, with the same viewing direction.
  • the upper lever arm 6b is seated in a recess 5e which is worked into the contour of the front of the chin part 5. This protects the upper lever arm 6d against unintentional actuation in the event of an impact.
  • a compression spring 11 Between the wall of the chin part and the back of the lever arm 6d sits a compression spring 11 which presses the lever into the position shown.
  • the chin guard 5 can be unlocked in two ways. In a normal case, the motorcyclist will grasp the shape 6a 'of the lower lever arm 6c' with his thumb - as is also shown in FIG. 1 - and press the opening button 6 'upwards in the pivoting direction.
  • the second possibility of unlocking the chin part is via the upper lever arm 6d '.
  • the locking mechanism can in turn be released via the locking bolt 8 and the snap spring 9.
  • the word "Press” can advantageously be written on the visible surface of the upper lever arm 6d.
