Definitions

  • the invention relates to a protective helmet comprising a system for adjusting the length of a head support independent of a system for adjusting the position of a neck strap.
  • Protective helmets are used, for example, in mountaineering or climbing to provide protection in the event of falling rocks or head impacts. They are therefore part of the essential equipment for climbers and mountaineers.
  • the document US 2015/0327617 discloses a protective helmet with a neckband that deforms to adapt to the size of the head.
  • the same user will have a head circumference that fluctuates according to the activities, which generally requires having a helmet with an adjustable head circumference or even having two different helmets. Indeed, in summer the helmet is worn directly on the head or on a thin cloth. On the other hand, in winter the user can wear a hat or a hood. If the helmet is used for canyoning, the helmet can be worn on the hood of the suit. Traditionally, depending on the size defined by the head circumference, the position of the helmet in relation to the median frontal plane changes, which can lead to discomfort or even unsuitability of the helmet.
  • the document EP0558427 describes a helmet with a headband in the form of a ring with a system for adjusting the perimeter of the headband by means of a rack system fixed to the crown.
  • the rack system allows the perimeter of the headband to be modulated as well as the front part and the occipital part of the head circumference in relation to the crown. This solution is complicated to implement and is expensive.
  • WO2005/016047 discloses a helmet having a headband according to the preamble of claim 1.
  • An object of the invention is a protective helmet, the position of the median frontal plane of the helmet of which can be easily moved relative to the position of the median frontal plane of the user for several head circumference adjustment values.
  • the neckband is mounted to pivot on the first and second fixing points around respectively two non-collinear and non-orthogonal pivot axes, the positions of the two pivot axes being unchanged relative to the cap with the evolution of the length of the head support.
  • the front portion and the first and second side portions of the head support define a plurality of predefined positions corresponding to a plurality of head support length values.
  • the first fixing point and the second fixing point are rigid and removable connection points.
  • the mechanical connection between the front portion of the head support and the cap defines at least two axes of rotation arranged such that when the front portion of the head support moves away from the front portion of the cap, the front portion of the head support moves closer to the top of the cap.
  • the means for adjusting the position of the neckband are formed by a flexible element connecting the neckband with the front part of the skullcap or head support and a blocker having a first state allowing sliding along the flexible element and configured to define multiple blocking positions of the blocker on the flexible element and a second state in which the blocker is fixed on the flexible element.
  • the invention also relates to a method of adjusting a protective helmet as described in independent claim 7, which allows better centering of the helmet on the head.
  • the method comprises dismantling the first and second fixing points relative to the skullcap before adjusting the length of the head support and reassembling the first and second fixing points before adjusting the spacing between the neckband and the front part of the head support.
  • THE figures 1, 2 And 3 represent a protective helmet 1 comprising a cap 2 made of a material preventing it from folding back on itself.
  • the cap 2 may preferably be made of plastic material, for example injected polycarbonate or ABS or polystyrene or expanded polypropylene, or any other plastic material, in particular injected plastic, thermoformed or foam.
  • the cap 2 comprises a frontal part 2a located at the front, that is to say close to the user's forehead, and an occipital part 2b located at the rear.
  • the frontal part 2a is separated from the occipital part 2b, by two lateral parts 2c respectively right and left.
  • the protective helmet 1 is provided with a head support 3 and a neck strap 4.
  • the head support 3 is fixed to the cap 2 so as to form a U.
  • the U-shaped head support 3 is closed by the neck strap 4 to go around the user's head.
  • the head support 3 comprises a front part 3a and two side parts 3b respectively right and left as illustrated in figures 3 , 10 and 11 .
  • the two side parts 3b are separated by the front part 3a.
  • the head support 3 is intended to come into contact with the user's head.
  • the front part 1a is intended to come into contact with the user's forehead while each of the parts lateral 3b is intended to come into contact with the lateral parts of the user's head.
  • the head support 3 is intended to separate the head and the cap 2.
  • the head support 3 is fixed to the cap 2. More precisely, the front part 3a of the head support 3 is fixed to the front part 2a of the cap 2 by one or more front fixing points 11. The two ends of the head support 3 are fixed to the side parts 2c of the cap 2 by first and second fixing points 6.
  • the first and second fixing points 6 are advantageously arranged in the rear part of the cap 2, that is to say in the rear half of the cap 2 relative to the median front plane of the cap 2.
  • the helmet 1 comprises head support adjustment means 3 which are configured to adjust the length of the head support 3.
  • the head support 3 is adjustable so as to define several different values of head support 3 length.
  • the length of the head support 3 is modified between the first and second fixing points 6.
  • the first and second fixing points 6 are fixed on the shell 2 independently of the length of the head support 3.
  • the adjustment means of the head support 3 are able to adjust the separation distance between the front part 3a of the head support 3 and the front part 2a of the cap 2.
  • Increasing the effective length of the head support 3 corresponds to a move closer together between the front part 3a of the head support 3 and the front part 2a of the cap 2.
  • Reducing the effective length of the head support 3 corresponds to an increase in the gap between the front part 3a of the head support 3 and the front part 2a of the cap 2.
  • the adjustment means modulate the length of the head support 3 so as to modulate the distance between the front part 3 of the head support 3 and the front part 2a of the cap 2.
  • Adjusting the length of the head support 3 makes it possible to define the position of the user's forehead relative to the front part 2a of the cap 2 and therefore intervenes in the centering of the head inside the helmet.
  • a head support 3 in the form of a U associated with ends fixedly mounted on the cap 2 the adjustment of the length of the head support head 3 allows the position of the front part 3a to be adjusted simply and precisely.
  • the neckband 4 is mounted to be movable relative to the front part 3a of the head support 3 and to the front part 2a of the skull cap 2.
  • the neckband 4 is mounted to be movable relative to the front part 3a of the head support 3 so as to modulate the space available between the neckband 4 and the front part of the skull cap 2 and to press the user's forehead against the front part 3a.
  • the movement of the neckband 4 makes it possible to define the spacing between the occipital part 2b of the skull cap 2 and the occipital bone.
  • the neckband 4 presses on the occipital part of the head to press the forehead against the frontal part 3a of the head support 3 and thus define the position of the head relative to the skullcap 2.
  • the helmet 1 comprises means for adjusting the position of the neckband 4 which are configured to define the position of the neckband 4 relative to the front part 3a of the head support 3.
  • the means for adjusting the neckband 4 are distinct from the means for adjusting the length of the head support 3 to independently adjust the neckband 4 and the head support 3.
  • the movement of the neckband 4 and the adjustment of the head support 3 make it possible to center the head in the skullcap 2 by independently defining the distance between the occipital part of the skullcap 2 and the neckband 4 on the one hand and the distance between the front part of the head support 3 and the front part of the skullcap 2 on the other hand.
  • the adjustment means of the neckband 4 make it possible to define the separation distance between the neckband 4 and the front part 3a of the head support 3.
  • the helmet 1 can be better centered on the user's head by using adjustment means independent of the position of the forehead relative to the frontal part of the cap 2 and the position of the occipital bone relative to the occipital part of the cap 2.
  • the means for adjusting the neckband 4 are fixed on the one hand to the neckband 4 and they are fixed on the other hand to the front part 2a of the cap 2 and/or to the front part 3a of the head support 3 so as to define the distance between the neckband 4 and the front part 3a of the head support 3.
  • the means for adjusting the neckband 4 are fixed to the front part 2a of the cap 2.
  • the adjustment means of the head support 3 are configured such that the front part 3a of the head support 3 is mounted to be movable relative to each of the side parts 3b in a longitudinal direction of the head support 3.
  • the longitudinal direction is substantially included in a transverse plane of the user. In the illustrated configuration, the head support 3 does not define a ring.
  • the longitudinal direction extends from one end of the head support 3 to the opposite end along the largest dimension. The longitudinal direction connects the two fixing points 6 with the cap 2.
  • the neckband 4 has two additional attachment points with the skull cap 2.
  • the two additional attachment points are fixed on the skull cap 2 independently of the length of the head support 3.
  • the neckband 4 can have any configuration insofar as the position of the neckband 4 is adjustable independently of the length of the head support 3.
  • the two additional attachment points of the neckband 4 correspond to the first and second attachment points 6 between the head support 3 and the skull cap 2.
  • the same attachment point 6 is used to attach the neckband 4 and the head support 3 to the skull cap 2.
  • the neckband 4 is pivotally mounted about at least one pivot axis 5 relative to the occipital portion 2b of the skull cap 2.
  • the neckband 4 is pivotally mounted relative to two pivot axes 5 which are not collinear and advantageously non-orthogonal. The movement of the neckband 4 relative to the front part 3a of the head support 3 results in a deformation of the neckband 4 so that in the absence of stress by the adjustment means of the neckband 4, the neckband 4 is in a rest position. The rest position is independent of the length of the head support 3.
  • the neckband 4 presses the user's forehead against the front part 3a of the head support 3, which results in a user whose head is offset towards the front part 2a of the cap 2.
  • FIG. figure 4 Such a configuration is illustrated in FIG. figure 4 .
  • This configuration can be a source of discomfort. It is therefore particularly interesting to bring the occipital part of the head closer to the occipital part of the cap 2.
  • the helmet according to the invention makes it possible to recenter the helmet by increasing the distance between the front part 2a of the cap 2 and the front part 3a of the head support 3 by reducing the length of the head support 3.
  • the neckband 4 is pivotally mounted and preferably by means of the two pivot axes 5 which are mounted fixed relative to the cap 2 independently of the length of the head support 3.
  • the two lateral parts 3b of the head support 3 are fixed on the two lateral parts 2b of the cap 2 so that the at least one pivot axis 5 is stationary relative to the cap 2.
  • the pivoting connection between the head support 3 and the neckband 4 does not move despite the modulation of the length of the head support 3.
  • the user defines the distance between the front part 3a and the front part 2a. He can then fix the helmet 1 on the head using the neckband 4 which deforms. The deformation of the neckband 4 is intended to push the forehead against the front part 3a.
  • the adjustment means of the head support 3 are configured to allow the definition of an infinite number of different values of length of the head support 3, for example by using a strap that cooperates with a strap blocker.
  • adjustment means that are configured so that the frontal part 3a and the occipital part 3b of the head support 3 define a plurality of predefined positions corresponding to a plurality of values of length of the head support 3, with a finite number of possibilities, for example less than 5 different adjustment possibilities.
  • the adjustment means are configured so as to define 2 or 3 different lengths of the head support 3.
  • This adjustment of the length of the head support 3 makes it possible to adapt a single dimension of cap 2 to a greater variety of user head circumference dimensions. Using a predefined number of head support length values 3 or less than 5 seems sufficient to ensure good comfort of use for different head sizes.
  • each lateral part 3b of the head support 3 is fixed to the lateral part 2c of the shell 2 by means of a rigid connection 6. It is particularly advantageous for each lateral part 3b of the head support 3 to be mounted removably relative to the lateral part 2c of the shell 2. This makes it possible to dismantle at least part of the head support 3 to facilitate its adjustment. It is also advantageous for the front part 3a of the head support 3 to be mounted immovably relative to the shell 2.
  • the two lateral parts 3b of the head support 3 are formed by two parts mounted movably relative to the front part 3a.
  • the two lateral parts 3b are mounted movably independently of each other relative to the front part 3a.
  • the two lateral parts 3b are connected to each other, on the one hand, by the front part 3a and connected to each other on the other hand by the neck strap 4.
  • Each of the two side parts 3b is fixed to the neckband 4 by means of a rotation shaft defining the axis 5.
  • the two pivot shafts 5 provide the connection between a connecting end of the neckband 4 and one of the two side portions 3b of the head support 3.
  • Each side portion 3b is fixed to the cap 2 such that the two connecting ends of the neckband 4 are fixed or substantially fixed relative to the cap 2.
  • each lateral part 3b of the head support 3 is removably mounted relative to the front part 3a of the head support 3 in order to facilitate the adjustment of the length of the head support 3 and the overlap distance between the front part 3a and the lateral part 3b.
  • the adjustment means of the head support 3 are configured to define a plurality of distinct adjustment positions defining several different values of length of the head support 3.
  • the front part 3a defines a plurality of protruding areas 7 and the side part 3b defines holes 8 which are inserted into the protruding areas 7. The cooperation between the protruding areas 7 and the holes 8 defines at least two different lengths of head support 3.
  • figure 5 illustrates a connection configuration between one end of the front part 3a and a side part 3b of the head support 3.
  • the protruding areas and the holes can be interchanged between the front part and the side part.

  • the front part 3a can define a protruding area 7 which cooperates with another hole 8 so as to define a second connection point which blocks the position of the front part 3a relative to the lateral part 3b and prevents the rotation of the lateral part 3b relative to the front part 3a and maintains the front part 3a and the occipital part 3b which prevents separation.
  • the front part 3a of the head support 3 is provided with two connection members configured to cooperate with two complementary connection members arranged on the occipital part 3b.
  • the figure 5 illustrates a configuration where the front part 3a and the side part 3b define a head support 3 of reduced length while the figure 7 illustrates a configuration where the frontal part 3a and the occipital part 3b define a head support of greater length.
