Description

APPUI-DOS A APPLIQUER CONTRE LE DOSSIER D' UN SIEGE DE DE UEHICULE.  BACK SUPPORT TO BE APPLIED AGAINST THE BACK OF A DEEP SEAT.

La présente invention concerne un appui-dos destiné à être appliqué comme accessoire orthopédique sur le dossier du siège d'un véhicule automobile, en vue de corriger le profil de ce dossier pour permettre de l'adapter aux exigences de chaque utilisateur. The present invention relates to a back support intended to be applied as an orthopedic accessory to the seat back of a motor vehicle, with a view to correcting the profile of this back to allow it to be adapted to the requirements of each user.

De façon plus précise, l'invention à pour objet un appui-dos, caractérisé par le fait qutil comprend un coussin muni de moyens de fixation servant à le fixer au dossier du siège en une position réglable en hauteur. More specifically, the invention relates to a backrest, characterized in that it comprises a cushion provided with fixing means serving to fix it to the seat back in a position adjustable in height.

De façon avantageuse, lesdits moyens de fixation sont constitués par un premier support, qui peut être fixé au dossier du siège et par un second support, portant le coussin et monté à coulissement sur le premier support, des moyens de blocage réglables étant prévus pour bloquer le second support sur le premier en toute position désirée d'utilisation. Advantageously, said fixing means consist of a first support, which can be fixed to the seat back and by a second support, carrying the cushion and mounted to slide on the first support, adjustable blocking means being provided for blocking the second support on the first in any desired position of use.

Grâce à cette caractéristique, on peut adapter très facilement le profil du dossier du siège en fonction des caractéristiques de chaque utilisateur. En outre, chaque utilisateur est en mesure d'effectuer, à tout instant, l'adaptation du profil du dossier du siège en fonction des besoins divers qui peuvent se présenter, par exemple, au cours d'un voyage de longue durée. Thanks to this characteristic, the profile of the seat back can be very easily adapted according to the characteristics of each user. In addition, each user is able to carry out, at any time, the adaptation of the profile of the seat back according to the various needs which may arise, for example, during a long trip.

Pour mieux faire comprendre l'ob3et de la présente invention on va en décrire ci-après, à titre d'exemple purement illustratif et non limitatif, un mode de réalisation représenté sur le dessin annexé. To better understand the ob3et of the present invention we will describe below, by way of purely illustrative and not limiting, an embodiment shown in the accompanying drawing.

Sur ce dessin
- la figure 1 montre, de façon schématique, comment s'utilise l'appui-dos selon l'invention
- la figure 2 est une vue en perspective éclatée de cet appui-dos ;
- la figure 3 est une coupe selon III-III de la figure 1 ; et
- la figure 4 est une vue, à plus grande échelle, d'un détail de la figure 3.On this drawing
- Figure 1 shows, schematically, how to use the backrest according to the invention
- Figure 2 is an exploded perspective view of this backrest;
- Figure 3 is a section on III-III of Figure 1; and
FIG. 4 is a view, on a larger scale, of a detail of FIG. 3.

L'appui-dos tel que représenté et désigné par 1 comprend un coussin profilé 3 que l'on peut appliquer, comme accessoire orthopédique, sur le dossier 2 du siège d'un véhicule automobile pour en corriger le profil et l'adapter aux exi gences de chaque utilisateur. Cet appui-dos 1 comprend un châssis 4, de forme générale courbe, qui peut épouser la forme courbe de la face avant du dossier 2 du siège. Ce châssis 4 est muni de nervures de renfort 5 et il comporte, au droit des côtés, deux bords 6 repliés en équerre, servant de guides latéraux. Sur chacun des côtés du châssis 4 sont pratiqués deux fentes 7, dans chacune desquelles est enfilé un segment de ceinture 8, que l'on peut relier, à l'aide d'une boucle ou agrafe, à un autre segment de ceinture porté par le côté opposé du châssis 4.La fixation des deux segments de ceinture 8 au châssis 4 est assuré par un pivot de fixation 10 enfilé, de ehaque côté de ce châssis dans deux manchons.9 qui, du fait qu'ils sont solidaires chacun de ltextrêmité d'un segment de ceinture 8, l'empêchent de s'échapper de la fente correspondante 7. Sur chacun des bords repliés 6 du châssis 4 est percée, dans la partie médiane, une fente longitudinale 11. On a désigné par 12 un châssis ayant, approximativement, la même forme que celle du châssis 4 et muni de nervures de renfort 13. Sur la face avant de ce châssis 12 est fixé le coussin 3 qui, présente une partie rétrécie 3a qui, en cours d'utilisation, est tournée vers le haut.Ce châssis 12 comporte sur ses côtés deux bords repliés 14, constituant deux guides latéraux qui s'adaptent de façon coulissante dans les guides latéraux 6 du châssis 4. Chaque bord replié 14 du châssis 12 est percé d'un trou 15 dans lequel est engagée une vis 16 munie d'une poignée de réglage 16a. Comme on le voit de façon plus détaillée sur la figure 4 chacune des vis 16 traverse la fente correspondante 11 du bord replié 6 du châssis 4 et se visse dans un trou taraudé percé dans une petite plaque 17 insérée entre la face arrière du châssis 12 et la face avant du châssis 4. The backrest as shown and designated by 1 comprises a profiled cushion 3 which can be applied, as an orthopedic accessory, to the backrest 2 of the seat of a motor vehicle to correct the profile and adapt it to the requirements. each user. This backrest 1 comprises a chassis 4, of generally curved shape, which can match the curved shape of the front face of the seat back 2. This chassis 4 is provided with reinforcing ribs 5 and it comprises, at the right of the sides, two edges 6 folded at right angles, serving as lateral guides. On each of the sides of the chassis 4 are made two slots 7, in each of which is threaded a belt segment 8, which can be connected, by means of a loop or clip, to another belt segment carried by the opposite side of the chassis 4.The attachment of the two belt segments 8 to the chassis 4 is ensured by a fixing pivot 10 threaded, on each side of this chassis in two sleeves. 9 which, owing to the fact that they are each secured the end of a belt segment 8, prevent it from escaping from the corresponding slot 7. On each of the folded edges 6 of the chassis 4 is pierced, in the middle part, a longitudinal slot 11. A 12 has been designated a chassis having, approximately, the same shape as that of chassis 4 and provided with reinforcing ribs 13. On the front face of this chassis 12 is fixed the cushion 3 which, has a narrowed part 3a which, in use, is facing upwards. This chassis 12 has on its sides two folded edges 14, constituting t two lateral guides which slide in the lateral guides 6 of the chassis 4. Each folded edge 14 of the chassis 12 is pierced with a hole 15 in which is engaged a screw 16 provided with an adjustment handle 16a. As seen in more detail in FIG. 4, each of the screws 16 passes through the corresponding slot 11 of the folded edge 6 of the chassis 4 and is screwed into a tapped hole drilled in a small plate 17 inserted between the rear face of the chassis 12 and the front of the chassis 4.

Pour monter l'appui-dos 1 sur le dossier 2 du siège d'un véhicule automobile, on fixe le châssis 4 à ce dossier 2 à l'aide de la ceinture 8. En raison du montage coulissant entre les bords repliés 6 et 14 qui font partie respectivement des châssis 14 et 12, l'utilisateur peut procéder à un réglage de la position en hauteur du coussin 3 pour adapter le profil du dossier du siège en fonction de ses besoins. Pour bloquer le coussin 3 à la position voulue, on serre les vis 16 dans la petite plaque 17, à l'aide de la poignée 16a. L'utilisateur peut également procéder ensuite à un réglage plus précis de cette position du coussin 3, en fonction des besoins variables qui peuvent se présenter, par exemple, au cours d'un voyage de longue durée. To mount the backrest 1 on the backrest 2 of the seat of a motor vehicle, the chassis 4 is fixed to this backrest 2 using the belt 8. Due to the sliding mounting between the folded edges 6 and 14 which are respectively part of the chassis 14 and 12, the user can adjust the height position of the cushion 3 to adapt the profile of the seat back according to his needs. To block the cushion 3 in the desired position, the screws 16 are tightened in the small plate 17, using the handle 16a. The user can also then proceed to a more precise adjustment of this position of the cushion 3, according to the variable needs which may arise, for example, during a long journey.

Dans l'exemple décrit ci-dessus, les moyens de blocage réglables sont constitués par des vis 16, mais il est bien entendu que, sans sortir du cadre de l'invention, l'on pourrait remplacer ces vis par des moyens de blocage rapides d'un autre type, par exemple par des dispositifs de blocage à came commandés par des leviers.  In the example described above, the adjustable locking means are constituted by screws 16, but it is understood that, without departing from the scope of the invention, these screws could be replaced by quick locking means of another type, for example by cam locking devices controlled by levers.
