Abstract

The device has two parts (1,2) which can be joined by a hinge (5) in two stable positions. Part (1) is attached to the upper seat belt roller (3) and the other part (2) exerts pressure on the belt to prevent it from automatically winding back up. Part (2) consists of a tongue (6) with a curved end, and has a cushion (9) on the surface facing the belt. The hinge (5-8) allows limited rotation of the tongue (6). Part (2) exerts pressure on the belt as it leaves the roller, by means of a cylindrical toothed wheel. ADVANTAGE - The vehicle passenger can manually lengthen the seat belt by a few centimetres, thus reducing the discomfort caused by pressure of the seat belt on the body.

Description

La présente invention concerne un dispositif permettant d'atténuer l'oppression permanente provoquée par les ceintures de sécurité à enrouleur installées dans la plupart des véhicules automobiles. The present invention relates to a device for alleviating the permanent oppression caused by the retractable seat belts installed in most motor vehicles.

Les ceintures de sécurité, si elles constituent un élément important de la sécurité des occupants dans les véhicules, sont aussi bien souvent synonymes d'inconfort. En effet, les plus répandues sont dotées de dispositifs qui enroulent automatiquement toute longueur superflue de ceinture; ce qui revient à dire qu'il existe un rattrapage des jeux permettant d'assurer une tension minimale. Cette caractéristique technique est avantageuse lorsque l'utilisateur s'extrait de son véhicule et que la ceinture ne sert plus : ès l'instant où il la déboucle, elle s'enroule automatiquement et vient se placer en un endroit aisément accessible, prête pour un nouvel usage. Seat belts, while an important part of occupant safety in vehicles, are also often synonymous with discomfort. In fact, the most widespread have devices that automatically wind up any unnecessary length of belt; This amounts to saying that there is a catching up of the games allowing to ensure a minimum tension. This technical characteristic is advantageous when the user extracts himself from his vehicle and the belt is no longer used: as soon as he unbuckles it, it rolls up automatically and comes to be placed in an easily accessible place, ready for a new use.

Toutefois, le rattrapage immédiat de tout jeu inutile nuit au confort des occupants, car la tension constante imposée par l'enrouleur automatique a pour effet d'exercer-une pression sur le corps en contact avec la ceinture ; ainsi, selon le placement des organes fixant le circuit de la-ceinture et la position de l'utilisateur, la pression pourra s'exercer au niveau de l'épaule, du cou, du ventre ou-de la poitrine. La gêne qui en résulte peut être préjudiciable, notamment si elle accroît le malaise de personnes supportant mal des trajets en automobile, ou si elle en provoque parce qu'elle se localise en des endroits très sensibles, par exemple à l'emplacement d'opérations chirurgicales ou de fractures récentes. However, the immediate recovery of any unnecessary play harms the comfort of the occupants, because the constant tension imposed by the automatic retractor has the effect of exerting pressure on the body in contact with the belt; thus, depending on the placement of the organs fixing the lap-belt circuit and the position of the user, the pressure may be exerted on the shoulder, the neck, the belly or the chest. The resulting discomfort can be detrimental, especially if it increases the discomfort of people who do not tolerate car journeys well, or if it causes it because it is located in very sensitive places, for example at the site of operations. surgery or recent fractures.

Le dispositif de la présente invention remédie à ces inconvénients sans empêcher le fonctionnement normal de l'enrouleur automatique, c'est-à-dire qu'il permet toujours les mouvements lents de l'utilisateur Vers l'avant, et qu'en cas de choc, la ceinture se bloque et maintient les occupants du véhicule contre leur siège, de sorte que l'efficacité de la ceinture n'est pas modifiée, mais au surplus la ceinture n'est plus sensible de la meme manière et n'èst plus ressentie comme une gêne. The device of the present invention overcomes these drawbacks without preventing the normal operation of the automatic rewinder, that is to say that it still allows the slow movements of the user forwards, and that in case shock, the belt locks and keeps the occupants of the vehicle against their seat, so that the effectiveness of the belt is not changed, but moreover the belt is no longer sensitive in the same way and is not more like an embarrassment.

Dans ce but, selon l'invention, la longueur entre le point de bouclage et l'extrémité supérieure du trajet suivi par la ceinture peut être allongée par rapport à celle que fournirait normalement l'enrouleur automatique à l'équilibre. Le réglage de la petite portion de longueur additionnelle est à la charge de l'occupant, quelques centimètres obtenus par exemple au moment de l'extension initiale étant suffisants pour garantir le confort. A cet effet, il manipule le dispositif qui se présente comme une languette articulée sur un support fixe et qui vient bloquer la ceinture au niveau de l'enrouleur supérieur afin d'empêcher que l'excédent de longueur ne soit réenroulé.La position du stème de l'invention, au niveau de l'enrouleur supérieur, permet de placer l'excédent dans le tronçon "utile", c'est-à-dire entre le point supérieur et celui de bouclage, et non pas. entre l'enrouleur automatique souvent situé au niveau du plancher et l'enrouleur supérieur. For this purpose, according to the invention, the length between the buckling point and the upper end of the path followed by the belt can be lengthened compared to that which the automatic winder would normally provide at equilibrium. The adjustment of the small portion of additional length is the responsibility of the occupant, a few centimeters obtained for example at the time of the initial extension being sufficient to guarantee comfort. For this purpose, it manipulates the device which is presented as a tongue articulated on a fixed support and which comes to block the belt at the level of the upper reel in order to prevent the excess of length from being rewound. of the invention, at the upper reel, allows to place the excess in the "useful" section, that is to say between the upper point and that of looping, and not. between the automatic reel often located at floor level and the upper reel.

Dans une description plus précise de l'invention, on se réfèrera aux figures placées en annexe, et pour lesquelles
- la figure 1 représenté une vue de face d'une configuration du dispositif,
- la figure 2 est une vue de côté, alors que
- les figures 3 et 4 font état d'une variante du dispositif, montrée suivant les mêmes vues qu'auparavant.
In a more precise description of the invention, reference will be made to the figures placed in the appendix, and for which
- Figure 1 shows a front view of a configuration of the device,
- Figure 2 is a side view, while
- Figures 3 and 4 show a variant of the device, shown in the same views as before.

Selon un premier exemple, le système de l'invention se compose de deux parties articulables (1) et (2) l'une par rapport à l'autre. Le premier élément (l) est de forme quelconque s'adaptant à l'enrouleur supérieur (3) sur lequel il est fixé. Selon une réalisation préférentielle, cet élément est triangulaire avec un sommet arrondi, et il est percé d'un orifice circulaire (6) permettant sa fixation. La base du triangle a une épaisseur équivalente à celle de la ceinture et comprend à ses deux extrémités les -deux parties femelles de la charnière (5). According to a first example, the system of the invention consists of two articulated parts (1) and (2) relative to each other. The first element (l) is of any shape adapting to the upper reel (3) on which it is fixed. According to a preferred embodiment, this element is triangular with a rounded top, and it is pierced with a circular orifice (6) allowing its fixing. The base of the triangle has a thickness equivalent to that of the belt and comprises at its two ends the two female parts of the hinge (5).

Le second élément (2) est constitué par une languette (6) dont une extrémité est recourbée vers l'intérieur de l'habitacle (T) alors que l'autre extrémité forme l'arbre (8) de la charnière ; la face en regard de la ceinture porte un patin ou coussinet (9). Il s'agit de l'élément fonctionnel du dispositif, qui réalise l'effet désiré. Grâce à la charnière (5)-(S), cette languette est mobile en rotation selon l'axe (8), mais cette rotation est d'amplitude limitée : le mouvement est possible entre deux points d'équilibre qui forment les deux positions ouverte et fermée. The second element (2) consists of a tongue (6), one end of which is curved towards the interior of the passenger compartment (T) while the other end forms the shaft (8) of the hinge; the opposite face of the belt carries a pad or pad (9). This is the functional element of the device, which achieves the desired effect. Thanks to the hinge (5) - (S), this tongue is movable in rotation along the axis (8), but this rotation is of limited amplitude: the movement is possible between two points of equilibrium which form the two positions open and closed.

Le fonctionnement est le suivant
- lorsque la languette est en position ouverte, le fonctionnement de la ceinture de sécurité est normal, le dispositif de l'invention n'a aucun effet sur le système préexistant. Au surplus, cela ne gêne pas le réenroulement automatique de la ceinture de sécurité, et la boucle arrivant en fin de course avec une certaine vitesse ne risque pas de casser la languette.
The operation is as follows
- When the tongue is in the open position, the functioning of the seat belt is normal, the device of the invention has no effect on the pre-existing system. In addition, this does not hinder the automatic rewinding of the seat belt, and the loop arriving at the end of the race with a certain speed does not risk breaking the tongue.

- En position fermée (voir figure 2), la languette exerce une pression sur la surface de la ceinture par l'intermédiaire du coussinet et empêche le réenroulement automatique même si la tension en amont de l'enrouleur supérieur est nulle. La charnière doit donc être configurée de telle sorte qu'en cette position', la languette soit coincée afin d'exercer une pression suffisante au niveau de la partie basse de l'enrouleur. - In the closed position (see Figure 2), the tongue exerts pressure on the surface of the belt via the pad and prevents automatic rewinding even if the tension upstream of the upper reel is zero. The hinge must therefore be configured so that in this position ', the tongue is jammed in order to exert sufficient pressure at the bottom of the reel.

Le bout recourbé permet une bonne préhension de la part de l'utilisateur, afin que la manipulation soit aisée
Selon une variante (figures 3 et 4), la partie (1) est très réduite alors que l'action de pression se fait par l'intermédiaire d'une molette cylindrique (10) placée sous la partie (2) et qui agit sur la ceinture au débouché de l'enrouleur supérieur. A cet effet, le patin s'introduit "dans la fenêtre de l'enrouleur destiné au passage de la ceinture.
The curved end allows a good grip on the part of the user, so that handling is easy
According to a variant (FIGS. 3 and 4), the part (1) is very small while the pressure action takes place by means of a cylindrical wheel (10) placed under the part (2) and which acts on the belt at the outlet of the upper reel. For this purpose, the pad is introduced "into the window of the reel intended for the passage of the belt.

Bien entendu, ces exemples ne sont qu'illustratifs et ne peuvent être considérés comme limitatifs, l'invention englobant également toutes variantes  Of course, these examples are only illustrative and cannot be considered as limiting, the invention also encompassing all variants
