Definitions

  • the invention relates to a crash helmet, consisting of a relatively thin and hard outer shell and a relatively thick and soft inner shell with at least one opening in the outer and the inner shell and at least one lamp which is at least partially disposed within an opening.
  • spacers ensure that there is a distance between the hard shell and the skull of the head in the normal state. Compared to a directly lying, hard shell, the impact speed is slightly reduced in case of contact. Another advantage is that the air space between the skull and the hard shell is used for ventilation and thus for the removal of sweat.
  • This configuration is usually referred to as a "protective helmet” and is z. B. for construction workers and miners a standardized protection device. In mining, it has long been known to provide such a protective helmet with a lamp.
  • helmets differ in that as a spacer between the head and thin, hard outer shell a much thicker, much softer inner shell is introduced. In the event of a collision, it ensures a continuous deceleration of the head, so that the impact speed of the head on the hard outer shell is significantly reduced.
  • crash helmets are used in the use of powered by muscle power vehicles such as bicycles or rudders or driving aids and sports equipment such as skateboards and inliners.
  • muscle power vehicles such as bicycles or rudders or driving aids and sports equipment such as skateboards and inliners.
  • sports equipment such as skateboards and inliners.
  • perspiration is permanently released from the head and has to be removed by air.
  • ventilation openings are common.
  • the openings were very welcome as vents to dissipate heat and sweat. Their almond shape was later transferred to the vents of current, clamshell helmets. As with the historic crash lids, their soft inner shell on impact provides a "crumple zone" that reduces the acceleration applied to the head by spreading the impact of a crash over a longer period of time, significantly reducing the likelihood of skull fracture becomes.
  • the helmet must be able to slide as little resistance as possible on the impact surface or the impact edge along. Otherwise, the resulting friction forces are transmitted via the crash helmet and the head to the cervical vertebrae, which can cause vertebral fractures and nerve damage, the so-called "whiplash", or threatens the final final cervical fracture.
  • the hard outer shell must have as low as possible a “sliding friction coefficient" when sliding on asphalt, stones and other expected surfaces. This requirement is met by numerous plastics.
  • the surface contour of the outer shell must be continuously curved and, if possible, should have no edges or even protruding parts.
  • brackets of the lights can be rammed into the head of the user in an impact from the impact surface through the ventilation openings and thereby increase the risk of punctured fractures of the skull.
  • the patent US 5, 871, 271, Chien describes a bicycle helmet, in whose ventilation holes LEDs are installed as a light source.
  • This patent provides, in addition to the ventilation openings in the soft inner shell further recesses in which z. B. a battery is housed.
  • the main disadvantage is that internals such as the battery, the protective effect of the helmet is reversed on impact to the contrary: Instead of spreading the impact force over a large area on the skull, it is concentrated by the non-compressible battery on the outer edge. As a result, an impact in the battery is a very high, in the illustrated embodiment FIG. 5 create linear strain on the human skull with the high risk of skull fracture at this site.
  • the invention has taken on the task of integrating into the openings of a crash helmet a lamp so that it does not affect the safety function of the helmet in an impact, and additionally improves the stability of the helmet something.
  • each luminaire is fixed to a crossbar which connects two opposite edges of the opening, in which it projects on both sides of the opening over its edge and is fastened with at least two bearing surfaces on the outer shell.
  • the crossbar By connecting two opposite edges of the opening, the crossbar ensures increased stability of the crash helmet. Since it is attached to the outer shell, it finds in the structure of the helmet the best possible grip and does not interfere with the protective function of the inner shell during the impact.
  • the lamp is mounted within the opening on the crossbar.
  • the luminaire is preferably arranged on the side of the traverse facing the center of the helmet. This ensures that a light in the rear part of the helmet in an impact is not driven by their inertial mass on and catapulted to the helmet actually to be protected, but is prevented by the Traverse because it is across the opening and is supported on the outer surface of the helmet.
  • the front in the direction of movement of the helmet lights are protected in a collision by the crossbar from spikes that would otherwise penetrate into the opening and thereby could press the light on the head.
  • the desirable on impact sliding ability of the helmet on the impact surface is not further limited.
  • the crossbar increases the effective outer surface of the helmet, thereby distributing the peak forces acting on the outer shell more evenly.
  • the traverse extends slightly beyond the contour of the outer shell, this is less advantageous than a flush with the contour of the helmet integration.
  • the part projecting beyond the contour first wears on the impact surface during sliding movements of the crash helmet, as it is rubbed off by friction, the crosshead is thereby sanded relatively quickly to a uniform course of the contour.
  • the crossbar protrudes only slightly beyond the contour, the impact will not cause an excessive concentration of impact forces in this area and the additional impulses that arise when a sliding movement of the helmet on the impact surface transferred to the cervical vertebrae are not too large. Nevertheless, in this case, the outstanding part of the contour of the traverse should be as flat as possible.
  • a lamp according to the invention is also suitable for retrofitting helmets.
  • the traverse can then be glued with at least one support surface at its two ends on the outer surface in the vicinity of the edge of an opening.
  • the traverse engages with a permanently elastic latching lug in a complementary counterpart in the outer shell.
  • this latching connection must be so stable that it holds the maximum expected forces in a collision forces and still so shallow building, that even at a significant compression of the helmet at this point does not cause a point overloading of the head.
  • both bearing surfaces of the traverse are concave and complementary to beads formed at the edges and form an undercut with respect to the beads of two opposite edges.
  • Such a connection can be formed as a latching connection, provided that the materials of the outer shell and traverse have a corresponding elasticity.
  • bearing surfaces are lowered into an approximately almond-shaped ventilation opening at the widest point from the outside and then within the opening in the direction of the Longitudinal axis to be moved until the two bearing surfaces rest on the beads of the edge. Since the concave bearing surfaces are formed complementary to the beads at the edges of the opening, and are aligned so that an undercut is formed, the traverse is secured with the concave bearing surfaces behind the beads.
  • the crossbar is inserted in a ventilation slot at the top of the helmet, which is aligned in the direction of movement of the helmet, then also has a rigidly fixed to the crossbar light in the direction of movement forward and / or backward. It is located essentially within the contour of the outer shell and therefore does not interfere with the impact.
  • the lamp via at least one hinge relative to the crossbar is pivotable, so that the direction of the light beam of the lamp can be repeatedly adapted to the current head posture.
  • the longitudinal axis of the luminaire can no longer be aligned tangentially to the front outer surface of the helmet. Then it must be pivotable relative to the crossbar. Since the lamp then protrudes from the opening Publ and beyond the contour of the helmet, must they are folded back on impact, which happens automatically by the belching on the impact surface.
  • the lamp finds a secure fit at any angle, the pivoting can be inhibited by a friction element or a locking element with several locking steps. Then the lamp remains in the desired position even when driving through a pothole.
  • a shock absorber can be provided which helps to reduce the forces occurring in the event of an impact when the light is swung back. Such a shock absorber is also useful if an automatic alignment of the lamp is provided, this can, for. B. the center of gravity of the lamp are arranged lower than the pivot axis of the respective joint. As a result, the exiting light beam after completion of the pivoting movement always in the desired direction.
  • the orientation of the lights depending on the current position of the head - also be done automatically.
  • an automatic pivoting drive for the lights is required.
  • the invention proposes that on a side surface a pendulum arm is pivotally mounted, which is mechanically or pneumatically connected to the pivotable lights and radiate the lights in the desired direction when pointing vertically downwards pendulum.
  • the invention proposes as a variant of a pneumatic connection.
  • a small pneumatic cylinder or - even easier - a bellows or a rolling bellows must be attached.
  • These pneumatic elements are interconnected by small air hoses.
  • the advantage is that the air hoses are inexpensive and without significant impairment of the protective effect of the crash helmet -. B. can be installed in the joint between the inner and outer shell.
  • pendulum and lights Another connection between pendulum and lights is a mechanism, either via pressure and tension rods or cables or chains. Also conceivable is an electromotive pivoting of each individual lamp. About a position sensor and a E-lektronikbau facia for evaluation of the position sensor then the electric motor will pivot the lamp accordingly.
  • Another way to compensate for movements of the head are multiple light sources in a lamp, of which only one is activated, which radiates approximately in the direction currently desired.
  • each lamp is an autonomous functional unit, that is in each lamp, a light source such.
  • a light source such.
  • B. a battery and that also a switch are installed in the housing of the lamp.
  • the invention recommends that lenses are installed in the lamp, which focus the emitted light.
  • the trusses of adjacent openings can be connected to a common light carrier, which runs on the outer shell. If this light carrier is only worked quite flat, so hardly protrudes beyond the contour of the crash helmet, it hardly hampers the optimal backup in the impact.
  • the helmet may be equipped with a fan that draws in ambient air and distributes it to the inner surface through tubes, hoses, or other channels within the inner shell.
  • a lamp with flashing light source can be arranged on the two longitudinal sides of a crash helmet. These turn signals can serve as direction indicator. To turn it off and on, the invention proposes a wireless activation and deactivation, e.g. B. from the handlebar of a bicycle.
  • Skateboard or Inline riders can activate the flashing light as well as the front or rear facing lights by a switch directly on the light.
  • both bearing surfaces of the traverse are glued not only to the outer shell but also to the inner shell. Depending on the dimensioning of the individual components, this further increases the stability of the crash helmet and also the stability of the luminaire attachment. If used for bonding surface portion of the inner shell extends at an acute angle to the contour of the crash helmet and therefore protrudes despite a relatively large adhesive surface or other, constructive reason, the crossbar only with a relatively small degree in the soft inner shell, in the event of a fall the passive one Effectiveness of compressing the soft inner shell is not significantly impeded.
  • the upper light 2 is still in the pivoted state in which it lies approximately in the plane of the outer shell 11 of the crash helmet.
  • the two lower lights 2 are pivoted so far with respect to the cross member 3 that their light exit surface 21 points forward or rearward in the direction of travel and thereby light beams 22 in the direction of movement (eg for lane illumination) and counter to the direction of movement (eg. as a tail light).
  • the trusses 3 according to the invention with the lights 2 pivotally attached thereto are also suitable for retrofitting existing helmets.
  • FIG. 2 the supervision is shown on a bicycle helmet, which corresponds to the in FIG. 1 is similar. Very conspicuous are the numerous openings 13 in the outer shell 11, which continue through the adjoining inner shell 12. At the edges 14 of the opening 13, the view of the cut edges of the thick and soft inner shell 12 becomes visible FIG. 2 characterized by irregular hatching.
  • a lamp 2 is fixed by means of a cross member 3 respectively. It can be seen how the Traverse 3 protrudes beyond the opening 13 and rests in the region of the outer shell 11.
  • four lights 2 forward and two lights 2 to the rear.
  • the two outer, forward facing lights are still pivoted into the contour of the outer shell 11, so that the lights could not radiate parallel to the other two lights 2.
  • FIG. 3 is a section through a crash helmet 1 with two lights 2 reproduced, which are secured by trusses 3 in the openings 13. For the sake of clarity, the lines of the helmet 1 located behind the cutting plane are not drawn.
  • FIG. 3 shown area corresponds approximately to the in FIG. 1 and FIG. 2 illustrated two middle, the forward facing group of four lights.
  • FIG. 3 In cross-section of FIG. 3 clearly shows how the two lights 2 are supported with their wing-like protruding bearing surfaces 31 on the outer shell 11. It is in FIG. 3 the retrofitting of a helmet by universally usable trusses 3 shown. The area adjoining the support surface 31 of the traverse 3, which includes the pivot axis 42 of the joint 4, forms a profile which is only approximately complementary to the profile of the edges 14. In FIG. 3 it becomes clear that the resulting small cavity is replaced by a - in FIG. 3 not shown - adhesive can be filled, so that the contact area between the cross member 3 and the crash helmet 1 is increased.
  • FIG. 3 is very easy to understand that the cross member 3 only slightly over the outer shell 11 to the outside (ie in FIG. 3 to the top) protrudes.
  • the cross member 3 with the attached light 2 pressed only slightly into the crash helmet 1.
  • FIG. 3 is comprehensible, as well as in a compression of the outer shell 11 compared to the very thick inner shell 12 to half the lights 2 still do not protrude beyond the inside of the compressed inner shell 12 and thus during the impact not in contact with the - not shown here - Head come.
  • FIG. 3 are the lights 2 on the pivot axis 42 relative to the cross member 3 pivotally. In the illustrated rest position, they thus do not protrude appreciably beyond the contour of the outer shell 11 or beyond the contour of the inner shell 12.
  • FIG. 4 the section is drawn by a traverse 3. Since the cut is placed in the middle of the here U-shaped traverse 3, only that part of the traverse 3 is to be seen as a cutting surface, which connects the two bearing surfaces 31 together.
  • FIG. 4 In FIG. 4 are drawn with dashed lines, the two positions of a built-in traverse 3 pivotally mounted light 2. In the lower of the two positions shown, the longitudinal axis of the lamp 2 is approximately parallel or tangential to - here not shown - outer shell 11. In the upper angular position of the lamp 2 it protrudes maximally from the crash helmet 1 out. As a result, the pivoting region 41 of the joint 4 with the swiveling axis 42 becomes clear.
  • FIG. 5 is the front of the in FIG. 4 cut lamp 2 shown.
  • the luminaire 2 has with its light exit surface 21 to the viewer and the pivot axis 42 of the joint 4 extends in the image plane.
  • Very clearly visible are the two bearing surfaces 31 of the traverse 3, which will rest on the Au ⁇ enschale 11 in the installed state.
  • the traverse 3 bulges in this embodiment spherical segment.
  • FIG. 6 is the supervision on the in FIG. 4 and FIG. 5 see the light unit 2 shown with its traverse 3.
  • the U-shaped configuration of the traverse 3 is clear in this embodiment.
