Definitions
- the present invention relates to an improved device for securing helmets, in particular protective helmets for drivers and passengers of motor vehicles, and in particular two- or three-wheeled vehicles.
- the invention relates to a protective helmet, in particular for pilots of land vehicles, of the type comprising on the one hand a rigid shell capable of being wrapped, by means of suitable padding, essentially the upper, posterior parts. and lateral of the head of the user by providing the latter with an opening for vision, this shell being practically fixed relative to the head when the helmet is in place, and on the other hand a lower and anterior rigid part, movable forward with respect to said shell and suitable for being secured thereto by suitable pivoting and / or locking means, said movable lower and front part containing a bead which, when said portion is secured to said shell, comes to take support under and around the user's chin.
- Helmets of this general type are described in documents DE-A-2 853 260 and US-A-3 362 403, but they do not have padding suitable for fitting around the rear part of the neck as well as take support under the suboccipital fossa of the wearer. Indeed, the padding of the shell of these known helmets extends only at the back of the head, without supporting or protecting the neck of the user. In addition, the opening of known helmets is too large to be able to ensure excellent securing on the wearer's head because said bead is here only a support mentioned which does not extend as far as the mandible of the user.
- the object of the present invention is to remedy these drawbacks of known helmets, and above all to ensure that, in the event of an accident, the helmet is more securely retained on the head of the user.
- a helmet of the general type described at the start will be, in accordance with the present invention, essentially characterized in that said padding of the shell is extended, at its rear and lower part, by padding capable of fitting around the rear part of the neck as well as being supported at the level of the sub-occipital pits of the user, and in that said bead, when said lower and anterior movable part is secured to said shell, also comes to bear on each side, under the mandible of the user, so that said padding and said bead together define an opening which surrounds the neck of the user, and is significantly narrower than the interior space of said shell.
- the front part can be disengaged for fitting or removing the helmet in different ways: according to one of the variants proposed, the front part can be completely uncoupled from the helmet (Figure A) and re-coupled by snap-fastening, locking or another on either side of it. According to another variant, this front part can be released by lateral pivoting around a hinge (FIG. B), the closing being effected by snap-fastening of a lock or other system on the opposite part. It can also be provided that the front part can move forward by sliding on two slides, and lock internally when closed.
- the front part can tilt forwards around an axis of rotation of the hinge type, for opening movements.
- This axis can be located above the orifice intended to clear the field of vision ( Figure D), or, preferably, below it ( Figure C).
- the front part can tilt forward around two axes of rotation placed laterally on each side towards the rear of the opening intended for the visual field.
- the locking will also be carried out by two side latches located at the base of the helmet (figure I).
- FIG. 1 we see laterally a helmet 11 of conventional shape shown schematically, dressed with a rigid movable part 12, made in principle of the same material as the shell, on which is attached a visor 13 in transparent or other material, allowing visibility.
- the above mobile part is equipped with two stops 14 and 14 '(in symmetry).
- the movable part 12 is disposed at the front of the helmet and moves forward and upward relative to its two lateral axes 15 and 15 ′ located next to the two upper angles of the vision slot.
- FIG. 11 illustrates an embodiment of the device according to the invention; thus, we see on each side a self-locking locking system 16-16 'cooperating with the fasteners.
- the fasteners 17 and 17 make it possible to maintain the two assembled parts (the mobile part with the helmet).
- a centering shoulder 18 guides the two parts relative to each other.
- the movable part 12 when closed, therefore represents the securing device of the invention.
- the padding 19 made of materials similar to those used for protection in the shell 11, comes to rest under the mandible, thus securing the helmet with the wearer's head.
- This bead is of course maintained over its entire length by the extension of the rigid part under the mandible, freeing only the passage of the neck.
- the front part of the neck is itself protected from the rigid material by the overflow of the bead 19 which can be seen in FIG.
- this system compared to a conventional strap, distributes the holding force, which makes it more comfortable.
- a padding 20 located at the base inferior posterior of the shell 11 will be adjusted around the nape of the neck in the same way and with the same precautions as the aforementioned bead.
- the movable part can be guided and braked in its opening by a special shaped tongue 21, which will slide in a slide forming an integral part of the helmet.
- Adjustable aerators 22 will preferably be made for the above reasons.
- the opening curve X-X 'of the movable part 12 due to the choice of the location of the hinge pin 15, voluntarily causes a slight jamming on the chin.
- This characteristic induces that in the event of the helmet being torn off, the mobile part 12 will always have a tendency to close, thus applying no effect in this critical phase, on the closing latch 16 in the unlocking direction, thus ensuring a very high security with regard to the helmet.
- the force in this case will be essentially supported by the articulation 15 as in the conventional case of a strap on its retaining rivets.
- the strap has a weak point at its closing loop, which is not the case in the method according to the invention, the device is made in a single rigid piece.
- the helmet 11 and its movable part 12 thus closing further under the wearer's head than in a conventional helmet and having no sharp angles at this location, there will be less risk of dangerous snagging of the helmet from below in the event of an accident.
- FIG. 111 illustrates a preferred embodiment according to the invention, consisting in extending the lower part of the helmet as a whole (shell and movable front part) by a sufficiently large return 23, and more particularly facing the neck and the larynx , this return being lined internally with an absorption layer 24 and a layer of honeycomb foam 25, more flexible for comfort, this in order to avoid that the edge of the edge of the helmet, during the possible and brutal rotation of it, following a shock, does not come to traumatize the larynx or the cervical vertebrae.
- the curve of this return will be plotted as a function of the apparent center of rotation “C R of the helmet, the latter being situated approximately in the vicinity of the geometric center of the upper hemisphere of the helmet.
- this center of rotation may vary slightly.
- the lower part of the helmet can be used which returns under the head and under the mandible at four privileged points: firstly for the front part of the helmet, on each side, under the mandible, just in front of the gonic angle and on each side of the larynx 26; in fact, at this point, at the opening of the jaw, the displacement of the mandible is slight, unlike that recorded at the tip of the chin, thus making it possible to release it a little below, while keeping the support in front of the chin 28.
- the support is carried out at the level of the sub-occipital fossa 27, on each side of the muscle masses surrounding the vertebrae, thus making it possible to further release the nape at the very delicate level of the cervical vertebrae.
- the invention finds an interesting application in the safety of cyclists, motorcyclists and racing drivers.
