Abstract

Device modifying the winder 5 of seat belts 1 for the purpose of eliminating the constriction of the chest which they bring about. This device, which is the size of a box of matches, consists of a ring 6 placed over the toothed wheel 3. On this ring, a lever bar 7 pushed by a coil spring 9 exerts permanent braking. This force is adjustable by means of a screw 10 which moves the fulcrum 8. To eliminate this braking when putting the belt on or rewinding it, a mechanical force from the foot suffices on a round-headed rod 13, or on the same round-headed rod which has become a switch if it actuates a small motor 15 which acts on the lever 12 and counterbalances the force of the coil spring 9.

Description

DESCRIPTION
Dispositif modifiant l'enrouleur des ceintures de sécurité dans le but de supprimer l'oppression qu'elles provoquent sur la poitrine.DESCRIPTION
Device modifying the retractor of seat belts in order to remove the oppression they cause on the chest.

Les dispositifs brevetés ces dernières années ne comblent pas les besoins d'un marché exigeant et immense et font souvent appel à des moyens très sophistiqués non conformes à l'esprit mécanique et simple de la ceinture actuelle. The devices patented in recent years do not meet the needs of a demanding and immense market and often use very sophisticated means that do not conform to the mechanical and simple spirit of the current belt.

Chaque pas fait pour se rapprocher de la ceinture idéale c' est à dire efficace, agréable à porter et simple dans sa construction doit être considéré avec attention.Each step taken to get closer to the ideal belt, that is to say, effective, comfortable to wear and simple in its construction must be considered with care.

Je propose pour me rapprocher le plus possible de ce but, d'ajouter à l'enrouleur, un petit système de freinage permanent que l'on ne débloque qu'au moment de son utilisation, c'est à dire pour la mettre en position d'efficacité ou pour lui permettre de se réenrouler ce pourquoi elle est conçue.I propose to get as close as possible to this goal, to add to the reel, a small permanent braking system that we do not unlock until its use, that is to put it in position of efficiency or to allow it to rewind what it is designed for.

Sur la fiv. 1 je représente schématiquement, grandeur nature, l'enrouleur tel qu'il existe maintenant. En tirant sur le baudrier (1) on enroule un ressort (2) par l'intermédiaire de l'axe (4). Ce ressort donne une tension suffisante pour réenrouler le baudrier (1). On the fiv. 1 I schematically represent, life-size, the reel as it exists now. By pulling on the harness (1) a spring (2) is wound up via the axis (4). This spring gives sufficient tension to rewind the harness (1).

La roue dentée (3) est solidaire avec le tamboujJsur lequel s'enroule la ceinture.C' est cette roue, qui par l'intermédiaire des dents et d'un cliquet placé en position excentrique, permet de bloquer le système dès qu'on déroule plus vite le baudrier.The toothed wheel (3) is integral with the tamboujJsur which wraps the belt. It is this wheel, which by means of the teeth and a pawl placed in an eccentric position, allows to block the system as soon as unrolls the harness faster.

Sur la fig.2 je propose de rajouter à la roue dentée, une couronne, qui devient l'élément sur lequel s'exerce un freinage (6) d'une force légèrement supérieure à la tension donnée par le ressort (2). Ce freinage permanent se fait par l'intermédiaire d'une barre de levier (7) qui repose sur le point d'appui (8). Le ressort à boudin (9) exerce sur l'extrémité de ce levier une force suffisante pour freiner la roue dentée. Le réglage de cette force se fait grâce à une vis (10) qui déplace le point d'appui (8) dans le sens désiré.  On fig.2 I suggest adding to the toothed wheel, a crown, which becomes the element on which braking (6) is exerted with a force slightly greater than the tension given by the spring (2). This permanent braking is done by means of a lever bar (7) which rests on the fulcrum (8). The coil spring (9) exerts on the end of this lever sufficient force to brake the toothed wheel. The adjustment of this force is done by a screw (10) which moves the fulcrum (8) in the desired direction.

Pour supprimer ce freinage et rendre ainsi pendant un temps voulu toute son efficacité à la ceinture il suffit d'exercer une certaine force sur le levier (12) à l'encontre du ressort à boudin (9) grâce à un cable relié à un champignon (13) actionné par le pied gauche du conducteur ou par le droit du passager. Un ressort (14) ramène le levier en en position initiale. To suppress this braking and thus make its belt effective for a given time, it suffices to exert a certain force on the lever (12) against the coil spring (9) thanks to a cable connected to a mushroom. (13) operated by the driver's left foot or by the passenger's right. A spring (14) returns the lever to the initial position.

On peut envisager de remplacer la force du pied par un système champignon - interrupteur actionnant un petit moteur 12 V (15) qui par l'intermédiaire d' un petit cable fait traction sur le levier (12). Cette solution ne change en rien la conception générale du dispositif qui reste entièrement mécanique comme est la ceinture de sécurité à enrouleur dans son principe. We can consider replacing the force of the foot with a mushroom-switch system actuating a small 12 V motor (15) which, by means of a small cable, pulls on the lever (12). This solution does not change the general design of the device which remains entirely mechanical as is the retractable seat belt in principle.

Le positionnement de ce dispositif par rapport à l'enrouleur est garanti par le lien commun entre ces deux parties et l'ancrage à la carrosserie. (16)  The positioning of this device relative to the reel is guaranteed by the common link between these two parts and the anchoring to the body. (16)

Claims (4)

REVENDICATIONS 1) Dispositif modifiant l'enrouleur des ceintures de sécurité caractérisé en ce qu'il s'adapte sur la roue dentée (5) sous la forme d'une couronne (6) sur laquelle s'exerce un freinage. 1) Device modifying the seat belt retractor, characterized in that it adapts to the toothed wheel (5) in the form of a crown (6) on which braking is exerted. 2) Dispositif selon la revendication 1 caractérisé en ce que le freinage de la couronne (6) et en conséquence du tambour sur lequel s'enroule le baudrier (5) est obtenu grâce à une barre de levier (7) à l'extrémité de laquelle un ressort à boudin (9) exerce une force qui est réglable. 2) Device according to claim 1 characterized in that the braking of the crown (6) and consequently of the drum on which the harness is wound (5) is obtained by means of a lever bar (7) at the end of which a coil spring (9) exerts an adjustable force. 3) Dispositif selon la revendication 2 caractérisé en ce que la force exercée par le ressort à boudin est réglée par un déplacement du point d'appui (8) grâce à une vis (10) qui permet de déplacer le chariot porteur de ce point d'appui (8) vers la gauche ou la droite en fonction des besoins. 3) Device according to claim 2 characterized in that the force exerted by the coil spring is adjusted by a displacement of the support point (8) with a screw (10) which allows to move the carrier carriage from this point d '' support (8) to the left or right as required. 4) Dispositif selon l'une des quelconques revendications précédentes caractérisé en ce que le levier (12) est tracté par un cable (11) relié à un champignon (13) actionné au pied. Un ressort (14) ramène le levier en position initiale.  4) Device according to any one of the preceding claims characterized in that the lever (12) is towed by a cable (11) connected to a mushroom (13) actuated at the foot. A spring (14) returns the lever to the initial position.
