Description

Bandeau appuie-front pour siège de passager Headrest for passenger seat

L'invention concerne un bandeau appuie-front destiné à soutenir la tête du passager qui somnole ou qui dort.The invention relates to a forehead support strip intended to support the head of the sleepy or sleeping passenger.

De nombreux efforts ont été faits pour améliorer le confort des sièges de passagers d'automobiles, d'avions et de trains. Certains dispositifs sont spécialement étudiés pour soutenir la tête du passager qui somnole ou qui dort. On connaît notamment des dossiers inclinables, des appuie-têtes postérieurs inclinables, des appuis latéraux escamotables. On connaît aussi des dispositifs de retenue de la tête constitués d'un bandeau passé autour de la tête du passager et d'un moyen de connexion au dossier ou à l'appuie-tête postérieur. Le brevet US 4707 031 présente deux modes de réalisation d'un dispositif de retenue de la tête : un mode "adulte" et un mode "enfant". Selon le dit brevet, le mode adulte comporte un premier bandeau passé autour de la tête, lequel bandeau est couplé à un deuxième bandeau passé autour du dossier. La description n'indique pas que le dit premier bandeau pourrait se distendre ou se rompre en cas de décélération importante ou en cas de choc. Le mode e réalisation "enfant" du brevet US 4 707 031 décrit une bande supplémentaire facultative pour "mieux résister aux mouvements latéraux de la tête (par rapport à l'appui-tête) par exemple au cours de décélération brusque" . Le brevet DE 9001789 décrit un dispositif de retenue de tête pour enfants qui comprend un bandeau frontal et un bandeau mentonnier, tous deux connectés au dossier. Le brevet GB 2 179852 décrit un support de tête, de hauteur réglable, connecté à l'appuie-tête postérieur ou au dossier. Le brevet US 5 081 714 décrit un premier bandeau passé autour de la tête et relié en arrière à un second bandeau passé autour du dossier. Les brevets DE 29610904 et DE 4306555 décrivent aussi des bandeaux en textile, connectés à l'appuie-tête postérieur. Le brevet US 4607885 décrit un support de tête pour enfant, en forme de U et rigide.Many efforts have been made to improve the comfort of passenger seats in cars, planes and trains. Certain devices are specially designed to support the head of the sleepy or sleeping passenger. Are known in particular reclining backrests, tilting rear headrests, retractable lateral supports. Head restraint devices are also known which consist of a strip passed around the passenger's head and of a means of connection to the backrest or to the rear headrest. US Patent 4,707,031 shows two embodiments of a head restraint: an "adult" mode and a "child" mode. According to the said patent, the adult mode comprises a first strip passed around the head, which strip is coupled to a second strip passed around the backrest. The description does not indicate that the said first strip could distend or rupture in the event of significant deceleration or in the event of an impact. The "child" embodiment of US Pat. No. 4,707,031 describes an optional additional strip to "better resist lateral movements of the head (relative to the headrest), for example during sudden deceleration". Patent DE 9001789 describes a head restraint for children which comprises a frontal band and a chin band, both connected to the backrest. Patent GB 2 179852 describes a head support, of adjustable height, connected to the rear headrest or to the backrest. US Patent 5,081,714 describes a first strip passed around the head and connected back to a second strip passed around the back. The patents DE 29610904 and DE 4306555 also describe textile headbands, connected to the rear headrest. US Patent 4607885 describes a head support for children, U-shaped and rigid.

Ces dispositifs de retenue de la tête présentent un grave inconvénient : ils relient fixement la tête du passager au dossier, ce qui peut être dangereux en cas de choc brutal ou en cas de décélération importante, en particulier si le thorax échappe à la ceinture de sécurité.These head restraint devices have a serious drawback: they fix the passenger's head to the backrest, which can be dangerous in the event of a sudden impact or in the event of significant deceleration, in particular if the chest escapes the seat belt.

Le but de l'invention est de remédier à cet inconvénient.The object of the invention is to remedy this drawback.

Pour mémoire, des dispositifs retiennent la tête en cas de choc, mais laissent la tête libre en utilisation normale. Le brevet FR 2 721 880 décrit une sangle de retenue de la tête en cas de changement brusque de mouvement. Le brevet DE 29516661 décrit un dispositif de retenue du casque du conducteur de voiture de sport. Le brevet US 4 909459 décrit un dispositif de retenue de la tête en cas de décélération supérieure à une valeur-seuil. Le brevet GB 1 497 847 décrit un dispositif de maintien de la tête qui laisse la tête libre lors d'une utilisation normale et retient la tête en cas d'accident. Le brevet WO 99/02376 décrit un bandeau qui retient la tête en cas de choc et qui permet à la tête de tourner librement en utilisation normale. Ces dispositifs sont hors du domaine de l'invention puisqu'ils ne soutiennent pas la tête en utilisation normale et la retiennent en cas de choc, ce qui est exactement le contraire de ce qui est recherché dans la présente invention.For the record, devices hold the head in the event of an impact, but leave the head free in normal use. Patent FR 2 721 880 describes a head retaining strap in the event of an abrupt change in movement. Patent DE 29516661 describes a device for retaining the helmet of a sports car driver. US Pat. No. 4,909,459 describes a device for retaining the head in the event of deceleration greater than a threshold value. Patent GB 1 497 847 describes a head holding device which leaves the head free during normal use and retains the head in the event of an accident. WO 99/02376 describes a headband which retains the head in the event of an impact and which allows the head to rotate freely in normal use. These devices are outside the scope of the invention since they do not support the head in normal use and retain it in the event of an impact, which is exactly the opposite of what is sought in the present invention.

L'invention a pour but de fournir un bandeau appuie-front qui puisse se distendre ou se rompre en cas de décélération importante ou en cas de choc, tout en assurant le soutien de la tête du passager en utilisation normale. Conformément à l'invention, ce but est atteint en incorporant au bandeau des zones extensibles ou des zones de moindre résistance, dites zones de "rupture". En cas de décélération importante ou en cas de choc, le bandeau selon l'invention laisse à la tête sa liberté de mouvement par rapport au dossier, évitant ainsi des traumatismes de la colonne cervicale. En particulier, si au cours d'un choc le thorax s'écarte du dossier ou échappe à la ceinture de sécurité, la tête du passager peut suivre le mouvement du thorax.The object of the invention is to provide a forehead support strip which can stretch or break in the event of significant deceleration or in the event of an impact, while ensuring the support of the passenger's head in normal use. In accordance with the invention, this object is achieved by incorporating into the strip stretch zones or zones of less resistance, called "break" zones. In the event of a significant deceleration or in the event of an impact, the strip according to the invention allows the head to move freely relative to the backrest, thereby avoiding trauma to the cervical spine. In particular, if during a shock the thorax deviates from the backrest or escapes the seat belt, the passenger's head can follow the movement of the thorax.

Description :Description:

Certains modes de réalisation de l'invention font usage de tissus connus, à adhésion réversible. Les dits tissus sont d'ordinaire utilisés pour la fermeture réversible de vêtements, de sacs ou de bandoulières. Les dits tissus comportent à leurs surfaces soit des boucles, soit des barbules. Les dites boucles et barbules s'accrochent respectivement lorsqu'on presse les deux surfaces l'une contre l'autre. Les dites boucles et barbules se décrochent lorsqu'on écarte les deux surfaces l'une de l'autre. Dans la suite de la description, la dénomination "bande à adhésion réversible" désignera une bande constituée avec du tissu à adhésion réversible tel qu'il est décrit au présent paragraphe.Certain embodiments of the invention make use of known fabrics, with reversible adhesion. Said fabrics are usually used for closing reversible clothing, bags or shoulder straps. Said fabrics have on their surfaces either loops or barbs. Said loops and barbs hang respectively when the two surfaces are pressed against each other. The said loops and barbs fall off when the two surfaces are separated from one another. In the following description, the designation "reversible adhesion band" will designate a band made with reversible adhesion fabric as described in this paragraph.

Figure 2 shows, according to the 1st embodiment of the strip (1), the spread strip (1), composed of the zones (10, 11, 12, 13, 14, 15, 16, 17, 18) and the tongue ( 55). Figures 3 and 4 show respectively the outer and inner faces of the strip (1) in the spread position.

Aucun élément n'est cousu ni collé au niveau de la face interne ni de la face externe des zones (11, 13, 15, 17) de la bande (3). En réponse à un appui, le tissu de la bande (3) des zones (11 , 13, 15, 17) a une réaction en trois temps :No element is sewn or glued at the internal face or at the external face of the zones (11, 13, 15, 17) of the strip (3). In response to a press, the fabric of the strip (3) of the zones (11, 13, 15, 17) has a reaction in three stages:

+ dans un premier temps, en cas d'appui faible, le tissu se distend facilement + dans un second temps, en cas d'appui moyen, le tissu arrive en limite d'allongement et résiste. + dans un troisième temps, en cas d'appui très important, le tissu se rompt.+ at first, in the event of weak support, the fabric easily distends + in a second time, in the event of average support, the fabric arrives at the limit of elongation and resists. + thirdly, in the event of very significant support, the tissue breaks.

L'absence d'élément rapporté au niveau des zones (11 , 13, 15, 17) permet au tissu de la bande (3) :The absence of any added element at the level of the zones (11, 13, 15, 17) allows the fabric of the strip (3):

+ de jouer un rôle d'extensibilité au niveau des zones (11 , 13, 15, 17) en cas de décélération faible ou en réponse à l'appui de la tête du passager. + de se distendre ou de se rompre au niveau d'une des zones (11 , 13, 15, 17) en cas de décélération importante ou en cas de choc. Les bandes élastiques et peu extensibles (21 ) et (22) des zones (12) et (16) limitent l'extensibilité du bandeau (1) en cas de décélération moyenne. Les bandes à adhésion réversible (19) et (23) des zones (10) et (18) permettent de fermer le bandeau appuie-front (1 ) et de régler la longueur du bandeau appuie-front (1) .+ play a role of extensibility at the level of the zones (11, 13, 15, 17) in the event of weak deceleration or in response to the support of the passenger's head. + to stretch or break at one of the zones (11, 13, 15, 17) in the event of significant deceleration or in the event of an impact. The elastic and poorly extensible bands (21) and (22) of the zones (12) and (16) limit the extensibility of the strip (1) in the event of average deceleration. The reversible adhesion bands (19) and (23) of the zones (10) and (18) make it possible to close the forehead support strip (1) and to adjust the length of the forehead support strip (1).

Selon une variante non illustrée de réalisation du bandeau, le bandeau (1) est coupé transversalement au milieu de la zone (14). Cette coupure permet à la zone (14) de se détacher des sangles (24) en cas de décélération importante ou en cas de choc, ce qui ajoute à la sécurité.According to an alternative embodiment of the strip, not illustrated, the strip (1) is cut transversely in the middle of the zone (14). This cut allows the area (14) to detach from the straps (24) in the event of significant deceleration or in the event of an impact, which adds to safety.

Lorsque le passager ne souhaite pas utiliser le bandeau, il peut ouvrir le bandeau (1 ) et appliquer les zones (10) et (18) sur des bandes à adhésion réversible prévues à cet effet sur le dossier ou sur les faces externes des zones (30 des sangles (24) (figure 5). Si la taille de l'appuie-tête le permet, les zones (10) et (18) peuvent aussi se chevaucher en arrière de l'appuie-tête et adhérer l'une à l'autre au moyen des bandes à adhésion réversible (19) et (23) (figure 6). Les autres modes de réalisation de l'invention prévoient aussi la possibilité de repliement des zones (10) et (18) en arrière et la possibilité de chevauchement des zones (10) et (18) en arrière de l'appuie-tête.When the passenger does not wish to use the strip, he can open the strip (1) and apply the zones (10) and (18) on reversible adhesion strips provided for this purpose on the backrest or on the external faces of the zones ( 30 of the straps (24) (Figure 5). If the size of the headrest allows, the areas (10) and (18) can also overlap behind the headrest and adhere to one the other by means of the reversible adhesion bands (19) and (23) (FIG. 6). The other embodiments of the invention also provide for the possibility of folding the zones (10) and (18) backwards and the possibility of overlapping zones (10) and (18) behind the headrest.

Selon un perfectionnement de l'invention, un dispositif rabattable (51) de protection contre la lumière est fixé sur le bord inférieur de la zone (10), au moyen d'une charnière textile. Le dit dispositif (51) peut être placé dans deux positions : une position abaissée dans laquelle il protège les yeux du passager contre la lumière, et une position relevée. Le dispositif (51) se fixe en position relevée au moyen d'une bande à adhésion réversible (52) placée sur le dit dispositif (51 ) et au moyen d'une bande à adhésion réversible (53) placée sur la face externe de la zone (10). Dans ce cas, la bande à adhésion réversible (57) est placée sur la face externe du dispositif (51). Une ficelle de suspension (56) permet de retenir le dispositif (51) en position abaissée . Un moyen connu permet de régler la longueur de la ficelle (56) et donc de régler l'inclinaison longitudinale du dit dispositif (51) en position abaissée. La figure 7 montre en perspective, en vue antéro-latérale, le bandeau (1) muni du dispositif (51) en position abaissée. Selon une variante non illustrée de réalisation du dispositif (51), le dit dispositif (51) peut être amovible.According to an improvement of the invention, a folding device (51) for protection against light is fixed on the lower edge of the zone (10), by means of a textile hinge. Said device (51) can be placed in two positions: a lowered position in which it protects the passenger's eyes from light, and a raised position. The device (51) is fixed in the raised position by means of a reversible adhesion strip (52) placed on said device (51) and by means of a reversible adhesion strip (53) placed on the external face of the zone (10). In this case, the reversible adhesion strip (57) is placed on the external face of the device (51). A suspension string (56) allows the device (51) to be retained in the lowered position. Known means makes it possible to adjust the length of the string (56) and therefore to adjust the longitudinal inclination of said device (51) in the lowered position. Figure 7 shows in perspective, in anterolateral view, the strip (1) provided with the device (51) in the lowered position. According to a variant of the device (51) not illustrated, said device (51) can be removable.

Selon le meilleur moyen de réaliser la bande (3), la dite bande est constituée d'un tissu (42) qui présente une élasticité en deux temps : dans un premier temps, en cas de décélération faible, le tissu est facilement extensible, puis au delà d'une limite d'allongement le tissu devient peu extensible. Le dit tissu (42) comporte deux sortes de fibres :According to the best means of producing the strip (3), the said strip consists of a fabric (42) which has elasticity in two stages: firstly, in the event of weak deceleration, the fabric is easily stretchable, then beyond an elongation limit the fabric becomes not very stretchy. Said fabric (42) comprises two kinds of fibers:

- des fibres rectilignes (40) composées de matériau élastique facilement extensible et disposées sensiblement parallèlement à la ligne médiane (35) du bandeau (1).- rectilinear fibers (40) made of easily extensible elastic material and arranged substantially parallel to the midline (35) of the strip (1).

- des fibres (41), composées de matériau élastique peu extensible et qui ont au repos un trajet curviligne, par exemple en accordéon ou en sinusoïde. La figure 8 montre schématiquement un exemple de réalisation du tissu (42) avec des fibres rectilignes (40) et des fibres curvilignes (41 ), le dit tissu (42) étant représenté au repos. Du point de vue fonctionnel :- Fibers (41), composed of elastic material which is not very extensible and which have at rest a curvilinear path, for example in accordion or in sinusoid. FIG. 8 schematically shows an embodiment of the fabric (42) with rectilinear fibers (40) and curvilinear fibers (41), the said fabric (42) being shown at rest. From a functional point of view:

- au repos, les fibres (40) et les fibres (41) ne sont pas sollicitées.- At rest, the fibers (40) and the fibers (41) are not stressed.

- en cas de décélération faible : seules les fibres (40) sont sous tension, les fibres (41) ne sont pas sollicitées.- in the event of weak deceleration: only the fibers (40) are under tension, the fibers (41) are not stressed.

- en cas de décélération moyenne : les fibres (40) sont sous tension, les fibres (41) ont un trajet rectiligne et sont sous tension et limitent l'allongement. Selon un mode simplifié de réalisation de la bande (3), la bande (3) est constituée d'un tissu-mousse synthétique en poiy-uréthane, tissu-mousse qui est d'ordinaire utilisé à des fins d'isolation. Ce tissu-mousse est peu extensible. Il se rompt en cas de tension importante. En revanche, sa résistance à la traction est suffisante pour soutenir la tête du passager qui somnole. Dans le cas où la bande (3) est constituée avec le dit tissu-mousse, seules les pièces (19,20,23,56) sont fixées sur la bande (3). Selon une autre variante de réalisation, la bande (3) est constituée d'un tissu-mousse synthétique en polystyrène à bulles fermées, tissu-mousse qui est d'ordinaire utilisé à des fins d'emballage. Ce tissu-mousse est d'un contact moelleux, ce qui améliore le confort du passager.- In case of medium deceleration: the fibers (40) are under tension, the fibers (41) have a straight path and are under tension and limit the elongation. According to a simplified embodiment of the strip (3), the strip (3) consists of a synthetic foam fabric made of polyurethane, a foam fabric which is usually used for insulation purposes. This foam fabric is not very stretchy. It breaks in the event of significant tension. However, its tensile strength is sufficient to support the head of the sleepy passenger. In the case where the strip (3) is formed with the said foam fabric, only the parts (19,20,23,56) are fixed on the strip (3). According to another alternative embodiment, the strip (3) consists of a synthetic foam polystyrene with closed bubbles, foam fabric which is usually used for packaging purposes. This foam fabric has a soft touch, which improves passenger comfort.

Description du dispositif de fixation :Description of the fixing device:

Selon le premier mode de réalisation du dispositif de fixation : - le bandeau (1 ) est situé entièrement en avant de l'appuie-têteAccording to the first embodiment of the fixing device: - the strip (1) is located entirely in front of the headrest

- une ou plusieurs sangles (24) sont serrées verticalement autour de l'appuie- tête postérieur et plaquent la zone (14) du bandeau (1) contre l'appuie-tête (figure 1). La ligne médiane (36) de chaque sangle (24) se situe sensiblement dans un plan vertical et longitudinal par rapport au véhicule. La zone (14) passe en avant de la zone (29) de chaque sangle (24). Le serrage des sangles (24) plaque la zone (14) contre l'appuie-tête. Description des sangles (24) : Chaque sangle (24) comporte deux faces :- one or more straps (24) are tightened vertically around the rear headrest and press the area (14) of the strip (1) against the headrest (Figure 1). The center line (36) of each strap (24) is located substantially in a vertical and longitudinal plane relative to the vehicle. The zone (14) passes in front of the zone (29) of each strap (24). Tightening the straps (24) presses the area (14) against the headrest. Description of the straps (24): Each strap (24) has two sides:

- une face, dite "interne", située au contact de l'appuie-tête postérieur connu ou au contact de la partie supérieure du dossier.- a face, called "internal", located in contact with the known posterior headrest or in contact with the upper part of the backrest.

- une face, dite "externe", située du côté opposé à la face interne. Chacune des sangles (24) est constituée :- a face, called "external", located on the side opposite to the internal face. Each of the straps (24) consists of:

- d'une bande (25) de tissu très peu extensible.- a strip (25) of very little stretch fabric.

- de pièces (31,32,33) collées ou cousues sur la bande (25), pièces qui seront décrites plus loin.- Parts (31,32,33) glued or sewn on the strip (25), parts which will be described later.

Chaque bande (25) comporte deux faces :Each strip (25) has two faces:

- une face, dite "interne", située au contact de l'appuie-tête postérieur connu ou au contact de la partie supérieure du dossier. - une face, dite "externe" située du côté opposé à la face interne.- a face, called "internal", located in contact with the known posterior headrest or in contact with the upper part of the backrest. - a face, called "external" located on the side opposite to the internal face.

Chaque sangle (24) comporte trois zones :Each strap (24) has three zones:

- une zone (28) qui se trouve en regard de la face postérieure du dossier.- A zone (28) which is located opposite the rear face of the backrest.

- une zone centrale (29) dont la partie la plus médiane se trouve en regard de la face antérieure de l'appuie-tête postérieur connu.- A central zone (29), the most median part of which is opposite the anterior face of the known posterior headrest.

- une zone (30) qui , lorsque la sangle (24) est fermée, se trouve en regard de la zone (28).- A zone (30) which, when the strap (24) is closed, is located opposite the zone (28).

Une bande à adhésion réversible (31) est cousue ou collée sur la face interne de la bande (25) au niveau de la zone (30). Sur la face externe de la bande (25) sont cousues ou collées : une bande à adhésion réversible (33) au niveau de la zone (30) et une bande à adhésion réversible (32) au niveau de la zone (28) La figure 9 montre une bande (25) étalée et la ligne médiane (36) de la sangle (24). La figure 10 montre une sangle (24) étalée, composée des zones (28) (29) (30). Les figures 11 et 12 montrent respectivement les faces externe et interne d'une sangle (24). Pour la mise en place des sangles (24), la bande à adhésion réversible (31) de la face interne de la zone (30) est appliquée sur la bande à adhésion réversible (32) de la face externe de la zone (28) (figure 13). Selon une variante du 1 er mode de réalisation du dispositif de fixation, lorsque l'appuie-tête postérieur n'est pas pourvu de montants verticaux, la sangle (24) est placée dans un plan sensiblement horizontal (figure 14). Dans ce cas, la zone (14) du bandeau (1) est fixée à la face externe de la zone (29) de la sangle (24) suivant un procédé connu, tel que par exemple collage, soudure ou couture. La dite fixation peut aussi se rompre en cas de décélération très importante ou en cas de choc, ce qui ajoute à la sécurité.A reversible adhesion strip (31) is sewn or glued to the internal face of the strip (25) at the level of the zone (30). On the external face of the band (25) are sewn or glued: a reversible adhesion band (33) at the level of the zone (30) and a reversible adhesion band (32) at the level of the zone (28) The figure 9 shows a band (25) spread and the center line (36) of the strap (24). FIG. 10 shows a spread strap (24), composed of the zones (28) (29) (30). Figures 11 and 12 show respectively the outer and inner faces of a strap (24). For the fitting of the straps (24), the reversible adhesion strip (31) of the internal face of the zone (30) is applied to the reversible adhesion strip (32) of the external face of the zone (28) (figure 13). According to a variant of the 1st embodiment of the fixing device, when the rear headrest is not provided with vertical uprights, the strap (24) is placed in a substantially horizontal plane (Figure 14). In this case, the zone (14) of the strip (1) is fixed to the external face of the zone (29) of the strap (24) according to a known method, such as for example gluing, welding or sewing. Said attachment can also break in the event of very significant deceleration or in the event of an impact, which adds to safety.

Deuxième mode de réalisation du dispositif de fixation : Selon le 2ème mode de réalisation, le dispositif de fixation du bandeau (1) au siège comporte une housse (43) qui est enfilée sur l'appuie-tête postérieur connu ou sur le dossier. La housse (43) est constituée d'un tissu élastique qui lui permet de s'adapter à la forme de l'appuie-tête postérieur ou à la forme du dossier. Sur la face postérieure de la housse (43) sont collées ou cousues une ou plusieurs bandes à adhésion réversible (50). La zone (14) du bandeau (1) est collée ou cousue sur la face antérieure (45) de la housse (43). La housse (43) est renforcée par une bande (54) de tissu peu extensible sur le pourtour de la dite housse, au niveau de l'insertion de la zone (14) du bandeau (1). La figure 15 montre en perspective, en vue antéro-latérale, la housse (43) munie de la bande de renfort (54) et des bandes à adhésion réversible (50). La figure 16 montre en perspective, en vue antéro-latérale, la housse (43) enfilée sur l'appuie-tête postérieur et le bandeau (1) fermé en avant au niveau des zones (10) et (18). Pour la clarté du dessin, la bande de renfort (54) n'est pas représentée sur la figure 16.Second embodiment of the fixing device: According to the 2nd embodiment, the device for fixing the headband (1) to the seat includes a cover (43) which is threaded onto the known posterior headrest or onto the backrest. The cover (43) is made of an elastic fabric which allows it to adapt to the shape of the rear headrest or the shape of the backrest. On the rear face of the cover (43) are glued or sewn one or more strips with reversible adhesion (50). The area (14) of the banner (1) is glued or sewn on the front face (45) of the cover (43). The cover (43) is reinforced by a strip (54) of fabric that is not very stretchy around the periphery of said cover, at the level of the insertion of the zone (14) of the strip (1). Figure 15 shows in perspective, in antero-lateral view, the cover (43) provided with the reinforcing strip (54) and reversible adhesion strips (50). Figure 16 shows in perspective, in antero-lateral view, the cover (43) threaded on the rear headrest and the strip (1) closed in front at the areas (10) and (18). For clarity of the drawing, the reinforcing strip (54) is not shown in FIG. 16.

3ème mocje de réalisation du dispositif de fixation : Le bandeau (1) passe en arrière de l'appuie-tête postérieur. Le bandeau est positionné au moyen de pattes (58) collées ou cousues sur l'appuie-tête postérieur (figure 17). La fixation des pattes (58) sur le dossier ou sur l'appuie-tête postérieur connu est suffisamment lâche de façon que les pattes (58) se détachent du dossier ou de l'appuie-tête postérieur connu en cas de décélération très importante ou en cas de choc, ce qui ajoute à la sécurité.3rd mocje of realization of the fixing device: The strip (1) passes behind the posterior headrest. The headband is positioned by means of tabs (58) glued or sewn onto the rear headrest (Figure 17). The attachment of the legs (58) on the backrest or on the known rear headrest is sufficiently loose so that the legs (58) detach from the backrest or of the known rear headrest in the event of very significant deceleration or in the event of an impact, which adds to safety.

4ème mode de réalisation du dispositif de fixation :4th embodiment of the fixing device:

Le bandeau (1) passe en arrière de l'appuie-tête postérieur. Deux sangles (24) sont serrées verticalement ou horizontalement autour de l'appuie-tφte postérieur. La bande à adhésion réversible (20) de la zone (14) du bandeau (1) est appliquée sur les bandes à adhésion réversible (33) des zones (30 des sangles (24). Cette manoeuvre solidarise la zone (14) du bandeau (1) avec la face postérieure de l'appuie-tête, par l'intermédiaire des sangles (24) (figure 18).The strip (1) passes behind the rear headrest. Two straps (24) are tightened vertically or horizontally around the rear headrest. The reversible adhesion band (20) of the zone (14) of the band (1) is applied to the reversible adhesion bands (33) of the zones (30 of the straps (24). This maneuver secures the zone (14) of the band (1) with the rear face of the head restraint, via the straps (24) (Figure 18).

Selon une variante de réalisation non illustrée, des bandes à adhésion réversible sont collées ou cousues directement sur la face postérieure de l'appuie-tête ou du dossier. Les dites bandes adhèrent à îa bande (20) de la zone (14) du bandeau (1). According to a variant embodiment not illustrated, strips with reversible adhesion are glued or sewn directly onto the rear face of the headrest or of the backrest. Said strips adhere to the strip (20) of the zone (14) of the strip (1).
