Abstract

The damper is for vibrations of a vehicle windscreen. It has a method of length adjustment and a flexible part which lessens vibration amplitudes. These two items are joined to a central core of two tubular parts connected to a joint with threaded ends. These ends screw into threaded parts in the tubular parts. In these, are a piston head in the retractable flexible head. The head presses against a spring giving flexibility. The threaded piston head screwed into the tube has a rod, giving length adjustment.

Description

La présente invention concerne un dispositif amortisseur de vibrations apte à être installé, par exemple, entre le tableau de bord et le pare-brise de véhicules à moteur, dans le but d'empêcher que le verre de ce dernier se brise sous l'impact d'une pierré.  The present invention relates to a vibration damping device able to be installed, for example, between the dashboard and the windshield of motor vehicles, in order to prevent the glass of the latter from breaking under impact. of a stone.

Comme on le sait, lorsqu'un pare-brise s'émiette sous le choc d'une pierre projetée par un véhicule qui précède, ceci est dû dans la plupart des cas, non pas à l'impact lui-même, mais aux vibrations que provoque cet impact. Le problème est donc d'empêcher ces vibrations de se produire pour qu'elles ne puissent causer la détérioration toujours regrettable et parfois très dangereuse du pare-brise. As we know, when a windshield crumbles under the impact of a stone thrown by a vehicle in front, this is due in most cases, not to the impact itself, but to the vibrations that causes this impact. The problem is therefore to prevent these vibrations from occurring so that they cannot cause the always regrettable and sometimes very dangerous deterioration of the windshield.

On utilise à cet effet un dispositif qui comprend un élément élastique destiné à diminuer l'amplitude des vibrations et avantageusement un moyen de réglage de sa longueur pour permettre de l'adapter aux conditions de montage. A device is used for this purpose which comprises an elastic element intended to reduce the amplitude of the vibrations and advantageously means for adjusting its length to allow it to be adapted to the mounting conditions.

L'invention a pour objet de perfectionner les dispositifs connus de ce type. The object of the invention is to improve the known devices of this type.

A cet effet, le dispositif selon l'invention comprend essentiellement un corps tubulaire formé de deux parties placées l'une à la suite de l'autre et reliées 1' une à l'autre par une pièce intermédiaire. Une de ces parties renferme un ressort de compression qui sollicite en permanence vers l'extérieur une tige rétractable. L'autre partie du corps tubulaire présente un taraudage dans lequel se visse l'extrémité filetée d'une autre tige, dont la position est donc réglable de façon à saillir plus ou moins hors de la dite partie. To this end, the device according to the invention essentially comprises a tubular body formed by two parts placed one after the other and connected to one another by an intermediate piece. One of these parts contains a compression spring which permanently urges outward a retractable rod. The other part of the tubular body has a thread in which the threaded end of another rod is screwed, the position of which is therefore adjustable so as to project more or less out of said part.

L'extrémité extérieure de chacune des tiges s'articule sur une embase apte à se fixer par une surface auto-collante sur la face intérieure du pare-brise ou sur le tableau de bord, respectivement. The outer end of each of the rods is articulated on a base capable of being fixed by a self-adhesive surface on the inner face of the windshield or on the dashboard, respectively.

Le montage du dispositif est facilité avantageusement par la possibilité de régler la position d'une des tiges et d'adapter ainsi la longueur de l'ensemble à la distance qui sépare le tableau de bord du pare-brise à 1' endroit choisi pour sa mise en-place.  The mounting of the device is advantageously facilitated by the possibility of adjusting the position of one of the rods and thus adapting the length of the assembly to the distance which separates the dashboard from the windshield at the location chosen for its implementation.

De toute façon, l'invention sera bien comprise à 1' aide de la description qui suit, en référence au dessin schématique annexé, représentant, à titre d'exemple non limitatif,une forme d'exécution de ce dispositif:
Fig. 1 est une vue en coupe longitudinale de l'en- semble du dispositif amortisseur selon l'invention, le corps tubulaire étant représenté en outre séparément en lévation;
Fig. 2 est une vue éclatée du dispositif de fig. 1;
Fig. 3 est une vue de face d'une des embases;
Fig. 4 est une vue en coupe longitudinale de la partie centrale du dispositif, à l'état rétracté au maxi mum. In any case, the invention will be clearly understood with the aid of the following description, with reference to the appended schematic drawing, representing, by way of nonlimiting example, an embodiment of this device:
Fig. 1 is a view in longitudinal section of the assembly of the damping device according to the invention, the tubular body being furthermore shown separately in elevation;
Fig. 2 is an exploded view of the device of FIG. 1;
Fig. 3 is a front view of one of the bases;
Fig. 4 is a view in longitudinal section of the central part of the device, in the retracted maximum state.

Comme on peut le voir, la partie centrale du dispositif selon l'invention est formée par un corps tubulaire fait de deux demi-corps identiques 7 et 15, munis à leurs extrémités en regard de taraudages Il et 16, respectivement, par lesquels ils se vissent sur un raccord central 6 muni à cet effet de deux tétons filetés. As can be seen, the central part of the device according to the invention is formed by a tubular body made of two identical half-bodies 7 and 15, provided at their ends facing threads II and 16, respectively, by which they are screw on a central connector 6 provided for this purpose with two threaded pins.

Dans le demi-corps 15 est logé un ressort hélico1- dal de compression 5, qui prend appui contre le téton adjacent du raccord central, ainsi qu'une tige 4, dont la tête en forme de piston s'appuie contre l'autre extrémité du ressort. La tige 4 est donc élastiquement rétractable. In the half-body 15 is housed a helical compression spring 5, which bears against the nipple adjacent to the central connector, as well as a rod 4, the piston-shaped head of which rests against the other end spring. The rod 4 is therefore elastically retractable.

Dans l'autre demi-corps 7 est montée une tige antagoniste 8, dont la tête 18 est filetée et se visse dans le taraudage 11, ce qui permet de régler sa position axiale rel- tivement au corps-tubulaire et de modifier ainsi la longueur de l'ensemble du dispositif. In the other half-body 7 is mounted an antagonist rod 8, the head 18 of which is threaded and screws into the thread 11, which makes it possible to adjust its axial position relative to the tubular body and thus to modify the length of the entire system.

Chacune des deux tiges 4 et 8 se termine à son extrémité extérieure par une partie aplatie munie d'une fente, partie qui s'engage dans une fente, respectivement 13 et 12 d'une protubérence 17 d'une embase, respectivement 1 et 10, et s'articule sur une cheville 2, 9, qui sert d'axe d'articulation. Each of the two rods 4 and 8 ends at its outer end with a flattened part provided with a slot, part which engages in a slot, respectively 13 and 12 with a protuberance 17 of a base, respectively 1 and 10 , and is articulated on a pin 2, 9, which serves as an axis of articulation.
