Abstract

The drum 10 of its casing 1 comprises an opening 15 beneath which is placed a bracket 3, the transverse web of which is hollowed out with a slit 30 allowing the passage of the strap 2. Two substantially triangular tongues 34, 35 stand up normally to the drum 10 on either side of the slit 30 in order to define a constant-spacing passage.

Description

IL existe de nombreux types d'enrouleurs de courroies ou sangles utilisés dans des domaines très divers, tels que Les enrouleurs de ceinture de sécurité pour automobile, ceux utilisés pour les sangles de sécurité des travailleurs effectuant des tâches dans des zones éLevées par rapport au sol, etc.... There are many types of belt reels or straps used in a wide variety of fields, such as seat belt reels for cars, those used for the safety straps of workers performing tasks in high areas above the ground , etc ....

Dans tous Les enrouleurs connus, La sangle s'enroule sur une bobine intérieure disposee dans un boitier muni d'une fente que traverse cette sangle. Dans Les enrouleurs considérés, Si la sangle est vriLLée, c'està-dire repliée sur elle-même dans le sens Longitudinal, elLe peut très bien pénétrer dans le boîtier en changeant d'orientation, de telle sorte qu'on risque des incidents de fonctionnement Lors de L'enroulement de ladite sangle. Elle peut encore se coincer dans ta fente. In all known reels, the strap is wound on an inner coil arranged in a housing provided with a slot through which this strap passes. In the reels considered, If the strap is twisted, that is to say folded back on itself in the longitudinal direction, it can very well penetrate into the case by changing orientation, so that there is a risk of incidents of operation When winding said strap. It can still get caught in your slit.

Les perfectionnements qui font l'objet de la présente invention visent à remédier à ces inconvénients et à permettre la réalisation d'un enrouleur dans lequel la sangle ne puisse pas se vriller. De pLus, con formément à l'invention, la sangle peut se présenter de manière décalée angulairement par rapport à la fente
A cet effet, l'enrouleur suivant l'invention comporte deux languettes substantiellement triangulaires qui se dressent normalement au boi- tier de l'enrouleur de part et d'autre de sa fente.The improvements which are the subject of the present invention aim to remedy these drawbacks and to allow the production of a reel in which the strap cannot twist. Furthermore, in accordance with the invention, the strap can be angularly offset from the slot.
To this end, the reel according to the invention comprises two substantially triangular tabs which normally stand on the housing of the reel on either side of its slot.

Suivant une autre caractéristique de L'invention, une barrette est disposée au niveau de chacune des extrémités de la fente pour permettre le guidage de la sangle si elLe se présente en biais par rapport audit boiter. According to another characteristic of the invention, a bar is arranged at each of the ends of the slot to allow the strap to be guided if it is at an angle to said housing.

Le dessein annexé, donné à titre d'exemple, permettra de mieux comprendre L'invention, Les caractéristiques qu'elle présente et les avantages qu'elLe est susceptible de procurer
Fig. 1 est une vue en perspective d'un enrouleur comportant application des perfectionnements suivant L'invention.The appended drawing, given by way of example, will make it possible to better understand the invention, the characteristics which it presents and the advantages which it is capable of obtaining.
Fig. 1 is a perspective view of a reel comprising application of the improvements according to the invention.

Fig 2 en est une coupe transversale suivant Le pLan de symétrie de l'enrouleur.  Fig 2 is a cross section along the plan of symmetry of the reel.

Fig. 3 est une coupe effectuée dans un plan perpendiculaire à celui dans Lequel se dépLace La sangle avant sa coopération avec le système suivant L'invention. Fig. 3 is a section made in a plane perpendicular to that in which the strap moves before its cooperation with the system according to the invention.

Fig. 4 est une vue semblable à celLe de fig. 2, mais ilLustrant une variante dans Laquelle le bottier est réalisé en matière plastique moulée. Fig. 4 is a view similar to that of FIG. 2, but illustrating a variant in which the boot is made of molded plastic.

On a illustré en fig. 1 et 2 un enrouLeur comprenant essentielle- ment un boîtier 1 à l'intérieurduquel est monté un dispositif d'enrou- lement non représenté pour une sangle 2. Le bottier est composé d'un tambour 10 cylindrique annulaire dont les deux bases sont fermées par un flasque 11. Un axe 12 tourillonne dans chacun des flasques pour porter le système d'enroulement non représenté de la sangle 2. Le tambour 10 est pourvu d'une chape 13 supportant un goujon 14 permettant la suspension de l'enrouleur.Le tambour est encore.muni d'une ouverture 15 (fig. 2) permettant le passage de la sangle 2 et qui est coiffé par un étrier 3 dont les joues 31 et 32 sont assujetties au tambour 10 de chaque côté des extrémités de l'ouverture 15 et entre lesquelles sont montés à rotation libre deux rouleaux 4 destines au guidage de la sangle 2. Illustrated in fig. 1 and 2 a reel essentially comprising a housing 1 inside which a winding device (not shown) for a strap 2 is mounted. The case consists of a cylindrical annular drum 10 the two bases of which are closed by a flange 11. An axis 12 journalled in each of the flanges to carry the winding system, not shown, of the strap 2. The drum 10 is provided with a yoke 13 supporting a stud 14 allowing the suspension of the reel. The drum est encore.muni une opening 15 (fig. 2) allowing the passage of the strap 2 and which is capped by a stirrup 3 whose cheeks 31 and 32 are subject to the drum 10 on each side of the ends of the opening 15 and between which are mounted free rotation two rollers 4 intended for guiding the strap 2.

Le voiLe transversal 33 de L'étrier 3 comprend une fente 30 assurant le passage de la sangle 2. Conformément à L'invention les deux bords de la fente 30 sont pourvus de deux languettes 34, 35 qui se dressent normalement au tambour 10 du boitier et dont lécartement constant est égal à la largeur de la fente 30. Chaque languette 34, 35 présente en profil une forme substantiellement triangulaire dont le sommet se trouve en gros dans l'axe de symétrie de la sangle 2. Un gousset 36, 37 réunit chaque languette à la partie correspondante du voile transversal 33 de manière à assurer la rigidité desdites languettes. The transverse section 33 of the stirrup 3 comprises a slot 30 ensuring the passage of the strap 2. According to the invention, the two edges of the slot 30 are provided with two tongues 34, 35 which normally stand on the drum 10 of the housing. and whose constant spacing is equal to the width of the slot 30. Each tongue 34, 35 has in profile a substantially triangular shape whose apex is roughly in the axis of symmetry of the strap 2. A gusset 36, 37 brings together each tongue to the corresponding part of the transverse web 33 so as to ensure the rigidity of said tongues.

Suivant une autre caracteristique de l'invention, chaque jonction du voile transversal 33 et des joues 31, 32 de l'étrier 3 porte une barrette cylindrique 38, 39 qui se trouve donc décalée vers l'extérieur par rapport aux arêtes externes de la fente 30. According to another characteristic of the invention, each junction of the transverse web 33 and the cheeks 31, 32 of the stirrup 3 carries a cylindrical bar 38, 39 which is therefore offset towards the outside with respect to the external edges of the slot 30.

Dans un mode d'exécution préféré de la disposition qui précède1 on réa lise le tambour 10' du boîtier 1 au moyen d'une pièce obtenue par moulage sous pression d'une matière plastique, de telle sorte que ledit tambour et L'étrier 3 ne forment qu'une seule et même pièce. Ainsi la fente 30' est un prolongement de l'ouverture 15' dont Les bords arrondis remplacent les rouleaux 4. In a preferred embodiment of the above arrangement, the drum 10 ′ of the housing 1 is made using a part obtained by pressure molding of a plastic material, so that said drum and the stirrup 3 are one piece. Thus the slot 30 ′ is an extension of the opening 15 ′, the rounded edges of which replace the rollers 4.

Grâce aux dispositions suivant L'invention, on crée dans une zone amont de la fente Lorsque La sangle 2 pénètre dans le boftier 1, une espece de patin double qui redresse Le sangle dans le cas ou elle se présenterait vrillée, de telle sorte qu'il ne peut se produire aucun coincement dans cette fente, ni à l'intérieur du dispositif d'enroulement. Thanks to the arrangements according to the invention, in a zone upstream of the slot, when a strap 2 enters the boftier 1, a kind of double pad which straightens the strap in the event that it becomes twisted, so that there can be no jamming in this slot or inside the winding device.

En outre, la présence des barrettes 38, 39 permet le fonctionnement parfait du système anti-vrillage constitué par Les languettes 34, 35 même si la sangle est orientée en biais par rapport au boftier.  In addition, the presence of the bars 38, 39 allows the perfect functioning of the anti-twisting system constituted by the tongues 34, 35 even if the strap is oriented at an angle relative to the boftier.

Il doit d'ailleurs être entendu que La description qui précede n'a été donnée qu'à titre.d'exemple et qu'elLe ne Limite nullement le domaine de L'invention dont on ne sortirait pas en remplaçant Les détails d'exécution décrits par tous autres équivalents.  It should moreover be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which no one would depart by replacing the execution details. described by all other equivalents.
