Description

Dispositif amortisseur de choc au niveau de la ceinture de sécurité. Shock absorber device at the seat belt.

La presente invention concerne un dispositif permettant d'obtenir une retenue progressive du corps de l'utilisateur par la ceinture de sécurité lors d un freinage brutal ou d'un choc avant.The present invention relates to a device making it possible to obtain progressive retention of the user's body by the seat belt during sudden braking or a front impact.

Les ceintures de sécurité en service å ce jour présentent l'inconvénient de retenir brutalement le corps de l'utilisateur occasionnant ainsi des blessures en cas de freinage brutal ou de choc avant.Seat belts in service to date have the disadvantage of brutally restraining the body of the user, thereby causing injury in the event of sudden braking or front impact.

En effet, lors d'un freinage brutal ou d'un choc avant, l'énergie cinétique emmagasinée par le corps de l'utilisateur projette celui-ci vers l'avant en entrainant la sangle (baudrier) de la ceinture qui se bloque quasi instantanément.Indeed, during brutal braking or a front impact, the kinetic energy stored by the body of the user projects it forward by driving the strap (harness) of the belt which is almost blocked instantly.

L'arrêt brutal se faisant d'abord au niveau de la fixation supérieure (fixe ou boucle pour ceinture å enrouleur) située au dessus de ltépaate de l'utilisateur, provoque douleur. blessure voire fracture af nIveau de celle-ci (clavicule. etc.).The sudden stop first at the upper attachment (fixed or buckle for a retractable belt) located above the shoulder of the user, causes pain. injury or even fracture in terms of it (collarbone, etc.).

La force exercée par le corps sur la partie supérieure de la sangle (basdrRerl de la ceinture provoque le glissement de celle c dans la boucle dL point d'ancrage sur plancher au centre du véhicule et donc l'écrasement de llabdomen par la sangle
(ventrale) de la ceinture occasionnant des blessures à ce niveau (rate. intestins,etc.). The force exerted by the body on the upper part of the strap (basdrRerl of the belt causes the sliding of that c in the loop of the anchor point on the floor in the center of the vehicle and therefore the crushing of the abdomen by the strap
(ventral) of the belt causing injuries at this level (spleen. intestines, etc.).

Le glissement de la sangle de la ceinture dans la boucle précitée provoque, de par son allongement, le glissement du thorax sur celle-ci et les blessures qui s'ensuivent (meurtrissures des chairs. ecchimoses. fractures , etc.)
La ceinture, selon l'invention. pallie à ces inconvénients a l'a;de d'un dispositif constitué de deux éléments fixés chacun à un point d'ancrage différent. The slipping of the strap of the belt in the aforementioned buckle causes, by its elongation, the sliding of the thorax on the latter and the injuries which follow (bruising of the flesh. Bruises. Fractures, etc.)
The belt according to the invention. overcomes these disadvantages a; of a device consisting of two elements each attached to a different anchor point.

Le premier élément est fixée au point d ancrage central du plancher du vehicule. Ce premier élément. constitué d'une boucle et d'un axe mobile ainsi que de cales en caoutchouc, a deux fonctions essentielles - en cas de freinage brutal ou de choc avant. il bloque automatiquement la sangle permettant ainsi une répartition homogène des forces sur la ceinture, - en outre, les cales de caoutchouc assurent un amortissement et donc une absorbtion progressive de l'énergie cinétique du corps de l'utilisateur au niveau de sa base.The first element is fixed to the central anchorage point of the vehicle floor. This first element. consisting of a loop and a movable axle as well as rubber shims, has two essential functions - in the event of hard braking or front impact. it automatically blocks the strap, thus allowing a homogeneous distribution of forces on the belt, - in addition, the rubber wedges provide damping and therefore a gradual absorption of the kinetic energy of the user's body at its base.

Le deuxième élément est fixé au point d'ancrage sur le montant au-dessus de l'épaule de l'utilisateur,.The second element is fixed to the anchor point on the upright above the user's shoulder.

Ce deuxième élément est constitué d'une boucle articulée (évitant la saillie dangereuse en cas de choc latéral) et d'une chappe coulissante sur celle-ci dans laquelle sont disposés des ressorts ; cet élément a pour fonction d'assurer un amortissement et donc une absorbtion progressive de l'énergie cinétique ' du corrs de l'utilisateur a son niveau supérieur (sans la restituer immédiatement)
Selon une première forme de réalisation. les ressorts d'amortissement sont de forme plate et ondulée, d'épaisseurs différentes assurant la progressivité.This second element consists of an articulated loop (avoiding dangerous protrusion in the event of a side impact) and a sliding cover on the latter in which springs are arranged; this element has the function of ensuring a damping and therefore a gradual absorption of the kinetic energy of the user's corrs at its higher level (without restoring it immediately)
According to a first embodiment. the damping springs are flat and wavy, of different thicknesses ensuring progressiveness.

Selon une deuxième forme de réalisation. les ressorts d'amortissement sont de forme cylindrique agissant a des mouvements différents (fonction de l'intensité des forces), assurant la progressivité.According to a second embodiment. the damping springs are cylindrical in shape acting at different movements (depending on the intensity of the forces), ensuring progressiveness.

Le dispositif complet met donc en présence les deux systèmes d'action précités qui assurent une répartition homogène des actions ou des forces par autoblocage de la sangle tt amortissement au point d'ancrage sollicite et apporte les avantages suivants - en cas de freinage brutal. i supprime les blessures dues au glissement de la sangle de ceinture et de l'arrêt brutal de celle-ci, - en cas de choc avant, il supprime ou diminue dans de très grandes proportions les effets du choc (blessures, fractures, etc.).The complete device therefore brings together the two aforementioned action systems which ensure a homogeneous distribution of actions or forces by self-locking of the strap tt damping at the anchoring point requested and brings the following advantages - in the event of brutal braking. i eliminates the injuries due to the slipping of the belt strap and the sudden stop of the latter, - in the event of a front impact, it eliminates or reduces in a very large proportion the effects of the impact (injuries, fractures, etc. ).

L'invention est exposée ci-après plus en détail en référence aux dessins annexés dans lesquels les figures représentent les différentes pièces nécessaires à la réalisation de l'invention et leur assemblage.The invention is set out below in more detail with reference to the accompanying drawings in which the figures represent the various parts necessary for carrying out the invention and their assembly.

Le premier élément du dispositif représenté en coupe sur la figure 2 est constitué d'un Té (1) solidarisé au verrouillage & poussoir sur le point d'ancrage du plancher au centre du véhicule, d'une boucle (3) dont la partie inférieure en forme de chape reçoit les cales en caoutchouc (4) et la partie supérieure du Té (1) retenus par les tétons (7). La partie supérieure de cette boucle (3) présente une lumière pour le passage de la sangle (6) qui enveloppe l'axe de translation (5) et son fourreau (8) guidés par le carter (2). Lors du réglage et du verouillage de la ceinture, l'élément du dispositif étant tenu par l'utilisateur à l'aide des extrémités de l'axe (5). le coulissement de la sangle est facilite par le fourreau (8) tournant librement sur l'axe (5).Après verrouillage de la ceinture, au repos la sangle coulisse sur le fourreau (8). Sous l'effet d'un freinage brutal ou d'un choc avant, l'axe (5) et son fourreau t8) guidés par le carter (2) sont translates assurant ainsi le blocage de la sangle (6) sur la boucle (3) . L'élasticité de la liaison (azDsorbtion progressive de l énersle cinetique) est
assurée par es cales en caoutchouc (4) situees entre la boucle
(3) et le Té de verrouillage (J)
Le deuxième élément du dispositif (père réalisation) représenté en coupe sur la figure 8 est constitué d'une ferrure de fixation
(9) (sur le montant de la carosserie au-dessus de l'épaule de
l'utilisateur) sur laquelle se pose le cache de protection (18), d'une boucle (11) articulée sur la ferrure (9) a l'aide de l'axe
(10), d'une chape (14) (avec taquets de guidage à sa partie suéieure) dans laquelle sont disposés des ressorts plats ondulés (15) de différentes épaisseur. Cette chape (14) est guidée a sa partie inférieure par les tétons (12) et les vis de serrage et retenue (13). APrès verrouillage de la ceinture, en position de repos, la sangle (6) de la ceinture coulisse sur la chape (14). Lors d'un freinage brutal ou d'un choc avant, le tirage soudain de la sangle (6) provoque le coulissement de la chape (14) sur ia boucle (1;) guidée par les tétons (12).The first element of the device shown in section in Figure 2 consists of a Tee (1) secured to the lock & push button on the floor anchoring point in the center of the vehicle, a loop (3), the lower part in the form of a yoke receives the rubber wedges (4) and the upper part of the tee (1) retained by the pins (7). The upper part of this loop (3) has a slot for the passage of the strap (6) which envelops the translation axis (5) and its sheath (8) guided by the casing (2). When adjusting and locking the belt, the device element being held by the user using the ends of the pin (5). the sliding of the strap is facilitated by the sheath (8) freely rotating on the axis (5). After locking the belt, at rest the strap slides on the sheath (8). Under the effect of brutal braking or a front impact, the axis (5) and its sheath t8) guided by the casing (2) are translates thus ensuring the blocking of the strap (6) on the buckle ( 3). The elasticity of the bond (progressive absorption of the kinetic kinetics) is
provided by rubber wedges (4) located between the buckle
(3) and the locking tee (J)
The second element of the device (father embodiment) shown in section in Figure 8 consists of a fixing fitting
(9) (on the upright of the body above the shoulder of
the user) on which the protective cover (18) is placed, a loop (11) articulated on the fitting (9) using the pin
(10), a yoke (14) (with guide tabs at its sueior) in which are arranged corrugated flat springs (15) of different thickness. This yoke (14) is guided at its lower part by the pins (12) and the clamping and retaining screws (13). After locking the belt, in the rest position, the strap (6) of the belt slides on the yoke (14). During sudden braking or a front impact, the sudden pulling of the strap (6) causes the clevis (14) to slide on the loop (1;) guided by the pins (12).

L'amortissement du choc provoqué par l'action (absorbtion progressive de l'énergie cinétique) est assure par les ressorts
(15) d'épaisseurs differentes permettant une retenue progressive.The shock absorption caused by the action (progressive absorption of kinetic energy) is absorbed by the springs
(15) of different thicknesses allowing progressive retention.

La restitution de l'énergie absorbé est ralentie a l'aide des vis de serrage et retenue (13) qui permettent å la chape (14) d'enserrer entre ses deux faces la base de la boucle (11). L'axe (10) assure l'articulation 9/11 et évite ainsi toute saillie possible de la boucle (li) par rapport au cache de protection
(18) en cas de choc latéral.The restitution of the absorbed energy is slowed down using clamping and retaining screws (13) which allow the yoke (14) to enclose the base of the loop (11) between its two faces. The axis (10) ensures the 9/11 articulation and thus prevents any possible projection of the loop (li) relative to the protective cover
(18) in the event of a side impact.

Le deuxième-élément (2ème réalisation) représente en coupe sur la figure 16 qui a les memes fonctions que celui de la première réa
lisation. s'en différencie de par les ressorts d'amortissement(19 guidés par la chape (17) recouverte du couvercle (16) qui sont de forme cylindrique de différentes longueurs. agissant en prenant appui sur la base de la boucle (11) å des moments differents en fonction de l'intensité des forces assurant ainsi la progressivité de l'absorbtion de l'énergie.The second element (2nd embodiment) represents in section in Figure 16 which has the same functions as that of the first sheave
reading. differs from it by the damping springs (19 guided by the yoke (17) covered with the cover (16) which are of cylindrical shape of different lengths. acting by resting on the base of the loop (11) å different moments depending on the intensity of the forces thus ensuring the progressiveness of the absorption of energy.

L'invention telle qu'elle est réalisée trouve son application dans l'industrie automobile ou accessoiriste, soit en tant qu'accessoire adaptable aux ceintures de sécurité existantes ou chez les constructeurs automobiles en tant qutélément constituant les ceintures de sécurité équipant les véhicules neufs. The invention as it is carried out finds its application in the automotive or accessory industry, either as an accessory adaptable to existing seat belts or in car manufacturers as part of the seat belts fitted to new vehicles.
