Abstract

The release unit comprises two pairs of weights (3), each pair being fixed to an arm. The centre point of this arm has a spur gear, forming a pivot and meshing with a double pinion gear (2). One set is positioned each side of a rack (1), retained by a spring. The smaller gear of each double pinion meshes with gear teeth each side of the rack and, when this latter is pulled continually rotates the gearing against the inertia of the weights until the unit is released. A short pull has no effect.

Description

1er. 1st.

: Système d'ancrage à ouverture automatique retardée même sous effet de traction continue.: Anchoring system with automatic delayed opening even under continuous traction effect.

Cette invention concerne les attaches de ceintures de se-
-curité et permet la séparation automatique totale des deux par
-ties du système d'ancrage sans intervention manuelle.
This invention relates to seat belt fasteners.
-security and allows total automatic separation of the two by
-ties of the anchoring system without manual intervention.

les systèmes d'attaches existant actuellement et équipant
l'ensemble des véhicules automobiles présentent un inconvénient
majeur: ils ne libèrent pas totalement l'usager après un choc
grave.
the existing fastening systems and equipping
all motor vehicles have a drawback
major: they do not fully release the user after a shock
serious.

la ceinture classique à tension fixe le maintient atta . - ché à son siège. the classic fixed-tension belt keeps him attacked. - checked at its headquarters.

la ceinture à enrouleur exige l'annulation quasi com-
-plète de l'effort de traction pour se relâcher et le libérer
partiellement.
the retractable belt requires cancellation almost
- full of tensile force to relax and release it
partially.

Cet ensemble mécanique très simple,objet de l'invention
utilise l'inertie des masses pour libérer progressivement l'éner-
-gie cinétique engendre lors d'une traction violente et brève
ou modérée et prolongée, appliquée à l'une ou aux deux parties
de cet ensemble et provoquer leur séparation totale.
This very simple mechanical assembly, object of the invention
uses the inertia of the masses to gradually release the energy
kinetic momentum generates during a violent and brief pull
or moderate and prolonged, applied to one or both parties
of this whole and cause their total separation.

Il est composé d'une partie fixe comprenant des masselot
-tes (3) mobiles sur le rayon de leur orbite par inertie,et so
-lidaires d'un système d'engrenages multiplicateurs (2), leur
imprimant un mouvement rotatif, relatif à l'effort de traction
reçu par l'intermédiaire d'une crémaillère (i) constituant la
partiemobile de l'ensemble.
It is composed of a fixed part including weights
are (3) mobile on the radius of their orbit by inertia, and so
-lidaries of a multiplier gear system (2), their
printing a rotary movement, relative to the tensile force
received through a rack (i) constituting the
part of the whole.

Te fonctionnement est le suivant:
la cremaillère,partie mobile de longueur variable,subiscant une traction,entraine 3a rotation de l'ensemble engrenages mass- -lottes et, la relation se terminant, s'échappe créant la séparaxa -tion des deux parties de l'ensemble d'ancrage.
The operation is as follows:
the rack, movable part of variable length, undergoing traction, causes 3a rotation of the gear assembly mass -lottes and, the relationship ending, escapes creating the separation of the two parts of the anchoring assembly .

L'echappement ou le non-echappment de la crémaillère sont modules suivant la puissance et la durée de la tration reçue:
Premier cas: la traction très violente et très brève n'autorise
pas la mise en rotation des masselottes et la cré mailler ne subit qu'un très faible mouvement de translation.
The exhaust or non-exhaust of the rack is modulated according to the power and the duration of the received tration:
First case: very violent and very brief traction does not allow
not the rotation of the weights and the mesh creation undergoes only a very slight movement of translation.

Deuxième cas: la traction très violente et d'une durée plus lon
-gue entraine la mise en rotation des masselottes qui,la traction exercée sur la crémaillère ayant cesse,continuent leur action par leur inertie propre et éjectent la crémaillère hors de la partie fixe.
Second case: very violent traction and of longer duration
-go causes the rotation of the weights which, the traction exerted on the rack having ceased, continue their action by their own inertia and eject the rack out of the fixed part.

Troisième cas: la traction est de puissance quelqonque mais con
tinue et prolongée, la crémaillère provoque la ro -tation de l'ensemble et s'échappe également réalisant la sépara -tion du système d'ancrage.
Third case: the traction is of some power but con
continuous and prolonged, the rack causes the rotation of the assembly and also escapes, achieving separation of the anchoring system.

L'idée-mère de cete invention réside en trois points prin -cipaux:
-- lors d'un choc léger ou moyen et bref,le système assure une entière sécurité (1er cas)
-- lors d'un choc très violent mais de durée plus longue le système maintient l'usager pendant le choc et le libère de sa ceinture après (2ème cas)
-- lorsqu'il y a successions de tractions dues à des"tonneaux", le système compensatoire de rappel de la crémaillère assu -re la fermeture pendant cette phase. Si l'usager se trouve en position anormale et exerce une traction continue sur sa ceinture alors qu'il lui est impossible d'en atteindre l'ouverture manuelle le système s'ouvre de lui même et le libère (3ème cas)
Cet ensemble possède un rappel,engrenages-masselottes,par ressorts,en position de repos qui permet la tension constante de la ceinture en compensant les courts mouvements de translation qui peuvent ê tre appliqués à la crémaillère et qui n'ont pas motivé son éjection.
The main idea of this invention resides in three main points:
- during a light or medium and brief impact, the system ensures complete safety (1st case)
- during a very violent shock but of longer duration the system keeps the user during the shock and releases him from his belt after (2nd case)
- when there are successions of pulls due to "barrels", the compensating system of recall of the rack assu -re closure during this phase. If the user is in an abnormal position and exerts a continuous pull on his belt while it is impossible for him to reach manual opening, the system opens by himself and releases him (3rd case)
This set has a reminder, gear-weights, by springs, in the rest position which allows the constant tension of the belt by compensating for the short translational movements which can be applied to the rack and which did not motivate its ejection.

Un système dtexentriques à commande manuelle permet en éloignant les ensembles engrenages-masselottes de son axe la ré- -insertion de la crémaillère,afin que celle-ci n'annule pas l'ac -tion des ressorts de rappel lors du réarmement de l'ensemble d'ancrage.  A manually operated dtexentric system allows the gear-flyweight assemblies to move away from its axis to re-insert the rack, so that the rack does not cancel the action of the return springs when rearming the anchor assembly.
