Description

L'addition con+ormément au brevet principal concerne un appui-tEte orientable et réglable pour dossiers de sièges des véhicules automobiles. The addition in accordance with the main patent relates to an adjustable and adjustable headrest for seat backs of motor vehicles.

L'objet de loaddition se rattache au secteur technique des accessoires et équipements prévus pour les passagers des véhicules automobiles. The object of loaddition relates to the technical sector of accessories and equipment intended for passengers of motor vehicles.

On rappelle selon une caractéristique à la base du brevet que I'appui-tête est constitué d'un cadre ouvert vers le bas, qui est fixé au dossier du siège de manière réglable angulairement à partir d'un plan vertical et d'une ossature montée pivotante par rapport a la partie inférieure du cadre et recevant à coulissement contrlé lwappui-tEte proprement dit ladi- te ossature est maintenue dans le plan du cadre en position d'utilisation normale, par des moyens de retenue élastiques et peut basculer vers l'avant du siège sous lFeffet d'une force d'appui exercée à l'opposé de son articulation au cadre puisrevenir en position lorsque l'action de la force qui a provoqué le basculement a cessé ses effets.  It is recalled according to a characteristic on the basis of the patent that the headrest consists of a frame open downwards, which is fixed to the seat back in an angularly adjustable manner from a vertical plane and a framework pivotally mounted relative to the lower part of the frame and receiving controlled sliding lwappui-tEte itself the said frame is maintained in the plane of the frame in the position of normal use, by elastic retaining means and can tilt towards front of the seat under the effect of a pressing force exerted opposite its articulation to the frame, then returning to position when the action of the force which caused the tilting has ceased its effects.

partir de cette conception de base, on a voulu étendre et améliorer les caractéristiques de loappui-tSte tout en les simplifiant d'une manière notable. From this basic design, we wanted to extend and improve the characteristics of loappui-tSte while simplifying them in a notable way.

Dans ce but, suivant une première caractéristique de l'addition, les moyens de retenue élastiques de l'ossature pivotante contre le cadre sont conformés et agencés à l'une de leurs extrémités en combinaison avec les branches latérales de l'ossa- ture, pour coopérer avec des encoches de prépositionnement formées facialement sur les bras recevant le coussin et montés à libre coulissement dans lesdites branches. To this end, according to a first characteristic of the addition, the elastic retaining means of the pivoting frame against the frame are shaped and arranged at one of their ends in combination with the lateral branches of the frame, to cooperate with prepositioning notches formed face on the arms receiving the cushion and mounted to slide freely in said branches.

Suivant une autre caractéristique, le dispositif de réglage angulaire du cadre par rapport au moyen de fixation du siège coopère avec deux butées fixes d'indexation pour avoir automatiquement la position angulaire désirée en vue de son blocage
L'invention est exposée ci-aprbs plus en détail a l'aide des dessins qui représentent seulement un mode d'exécution.According to another characteristic, the device for angular adjustment of the frame relative to the means for fixing the seat cooperates with two fixed indexing stops so as to automatically have the desired angular position with a view to blocking it.
The invention is set out below in more detail with the aid of the drawings which represent only one embodiment.

La figure i est une vue de face de l'appui-tete
la figure 2 est une vue partielle de coté de l'appui tête F
les figures 3 et 4 montrent le réglage angulaire du cadre par rapport au moyen de fixation du siège.Figure i is a front view of the headrest
Figure 2 is a partial side view of the head support F
Figures 3 and 4 show the angular adjustment of the frame relative to the seat fixing means.

On rappelle pour une meilleure compréhension de la suite de la description, que I'appui-tête comprend essentiel le- ment un cadre ouvert (1) et une ossature (2) recevant le coussin (15). L'ossature (2) est articulée par ses branches (2a) sur les montants (la) du cadre (i) agencé pour autre fixé d'une manière réglable angulairement au dossier du siège. En outre, l'ossature (2) est maintenue dans le plan du cadre (1) par des ressorts en épingle (4) qui lui assurent son rappel permanent quand la force qui a provoqué son basculement a cessé. It will be recalled for a better understanding of the rest of the description, that the headrest essentially comprises an open frame (1) and a framework (2) receiving the cushion (15). The frame (2) is articulated by its branches (2a) on the uprights (la) of the frame (i) arranged for another fixed in an angularly adjustable manner to the seat back. In addition, the frame (2) is held in the plane of the frame (1) by pin springs (4) which ensure its permanent return when the force which caused its tilting has ceased.

Selon l'addition, pour le réglage en hauteur des bras (14) recevant à libre articulation le coussin (15) et leur blocage en position, l'extrémité (4b) des ressorts (4) est convenablement recourbée pour coopérer, au travers d'une lumière (7b) formée transversalement dans l'épaisseur des branches (2a), avec des crans (14c). Ces crans ou autres empreintes en creux (14,) sont formés facialement sur les bras (14) (figure 1) et constituent chacun une rampe pour le relevage manuel automatique des bras (14) Les montants latéraux -(la) du cadre (1) ont une section transversale en U et font ainsi office de chape pour lvar- ticulation des branches (2a).Les ailes des montants (la) sont également entaillées pour permettre le passage des brins (4b). According to the addition, for the height adjustment of the arms (14) receiving the articulation of the cushion (15) and their locking in position, the end (4b) of the springs (4) is suitably bent to cooperate, through 'a light (7b) formed transversely in the thickness of the branches (2a), with notches (14c). These notches or other indentations (14,) are formed face on the arms (14) (Figure 1) and each constitute a ramp for the automatic manual lifting of the arms (14) The lateral uprights - (la) of the frame (1 ) have a U-shaped cross section and thus act as a yoke for variculation of the branches (2a). The wings of the uprights (la) are also notched to allow the passage of the strands (4b).

Dans la forme de réalisation illustrée, la traverse supérieure du cadre (1) est remplacée par un axe longitudinal (18) fixé sur les montants (la) en débordement latéral desdits montants (la). Les extrémités épaulées de l'axe (18) forment une portée cylindrique (ira) pour le montage à libre articulation, au moyen de pattes (19a), d'une traverse (19) agencée pour entre fixée sur le dossier du siège. In the illustrated embodiment, the upper cross member of the frame (1) is replaced by a longitudinal axis (18) fixed on the uprights (la) projecting laterally from said uprights (la). The shouldered ends of the axis (18) form a cylindrical bearing surface (ira) for mounting with free articulation, by means of lugs (19a), of a crosspiece (19) arranged for between fixed on the seat back.

Llune des pattes (19a) de la traverse de fixation
(19) est prolongée en direction du bas par une plaque en secteur
(20) percée d'au moins deux orifices (20a) en arc de cercle destinés à coopérer avec le doigt (9) logé par exemple dans le fourreau (10) solidaire d2un montant (la). La commande en translation du doigt (9) peut autre effectuée par tout moyen connu et approprié du type de celui décrit dans le brevet principal.One of the legs (19a) of the fixing crossmember
(19) is extended towards the bottom by a sector plate
(20) pierced with at least two orifices (20a) in an arc intended to cooperate with the finger (9) housed for example in the sheath (10) integral with an upright (la). The control in translation of the finger (9) may otherwise be carried out by any known and appropriate means of the type described in the main patent.

Dans l'exemple illustré dans l'addition, le doigt (9) est assujetti à un levier (21) articulé sur le montant (la) et commandé en pivotement par une tringle de manoeuvre (22). Comme déjà indiqué, le doigt (9) est rappelé en position par le ressort 513) positionne dans le fourreau (105. Il en résulte donc, selon la position du doit (9) dans l'un des orifices (2raz du secteur (20), deux positions angulaires différentes du cadre (1) par rapport à la traverse de fixation (19). In the example illustrated in the addition, the finger (9) is subject to a lever (21) articulated on the upright (la) and pivotally controlled by an operating rod (22). As already indicated, the finger (9) is returned to position by the spring 513) positioned in the sheath (105. This therefore results, depending on the position of the must (9) in one of the orifices (2raz of the sector (20 ), two different angular positions of the frame (1) relative to the fixing crosspiece (19).

Suivant une autre caractéristique, l'axe (18) est asservi à un ressort de rappel (23) dont les brins coopèrent en appui avec la traverse (19) d'une part et le montant (lb) par exemple, autre part. Cet axe (18) présente en outre deux butees fixes d'indexation (24) et (25) coopérant alternativement avec la traverse de fixation, selon le positionnement angulaire relatif du cadre (1). According to another characteristic, the axis (18) is controlled by a return spring (23) whose strands cooperate in support with the crosspiece (19) on the one hand and the upright (lb) for example, on the other hand. This axis (18) also has two fixed indexing stops (24) and (25) cooperating alternately with the fixing cross member, according to the relative angular positioning of the frame (1).

Enfin, on rappelle, comme déjà décrit et illustré dans le brevet principal, que le coussin ou têtière (15) est monté d'une manière auto-orientable en bout des bras (14). Finally, it is recalled, as already described and illustrated in the main patent, that the cushion or headrest (15) is mounted in a self-orientable manner at the end of the arms (14).

Les avantages ressortent bien de la description, en particulier, on souligne, en plus des avantages indiqués dans le brevet :
- la simplicité de réalisation
- la facilité de réglage
- la fiabilité du fonctionnement.The advantages emerge clearly from the description, in particular, it is emphasized, in addition to the advantages indicated in the patent:
- the simplicity of realization
- ease of adjustment
- reliability of operation.

Les différentes caractéristiques décrites et il les tries constituent un repose-tEte anti-choc. fonctionnel, conf or- table et assurant une sécurité totale non seulement aux passagers avant mais également aux passagers arrière.  The various characteristics described and the sorts constitute an anti-shock headrest. functional, comfortable and ensuring total safety not only for front passengers but also for rear passengers.
