Abstract
Description
La présente invention a pour objet un appui-te te pour siège de véhicule automobile qui est muni d'appuis latéraux; ces derniers évitent au passager en état de somnolence que sa tete bascule lors des virages.The subject of the present invention is a support for the seat of a motor vehicle which is provided with lateral supports; the latter prevent the drowsy passenger from tilting his head during turns.
Cet appui-tete est caractérisé en ce qu'il est à géométrie variable et peut occuper une première position dans laquelle les appuis latéraux sont escamotés et une deuxième position dans laquelle ces appuis latéraux sont en position active.This headrest is characterized in that it has variable geometry and can occupy a first position in which the lateral supports are retracted and a second position in which these lateral supports are in the active position.
Dans un premier mode de réalisation, les appuis latéraux sont fixes par rapport à l'appui arrière et l'appui-tete est monté pivotant d'environ 900 autour d'un axe transversal par rapport à l'armature du siège.In a first embodiment, the lateral supports are fixed relative to the rear support and the headrest is pivotally mounted by about 900 around an axis transverse to the frame of the seat.
Dans un second mode de réalisation les appuis latéraux sont montés coulissants horizontalement par rapport à l'appui arrière.In a second embodiment, the lateral supports are mounted to slide horizontally relative to the rear support.
On a décrit ci-après, à titre d'exemples non limitatifs, deux modes de réalisation de l'invention avec référence aux dessins annexés dans lesquels
La Figure 1 est une vue en perspective d'un
premier mode de réalisation, les appuis latéraux
étant en position inactive;
La Figure 2 est une vue semblable à la Figure 1,
les appuis latéraux étant en position active;
La Figure 3 est une vue en plan d'un détail;
La Figure 4 est une vue en plan d'un second
mode de réalisation;
La Figure 5 est une vue en coupe verticale d'un
détail;
La Figure 6 est une vue en coupe horizontale
d'un autre détail;
La Figure 7 est une vue en coupe d'un autre
détail.Two embodiments of the invention have been described below, by way of non-limiting examples, with reference to the appended drawings in which
Figure 1 is a perspective view of a
first embodiment, the lateral supports
being in the inactive position;
Figure 2 is a view similar to Figure 1,
the lateral supports being in the active position;
Figure 3 is a plan view of a detail;
Figure 4 is a plan view of a second
embodiment;
Figure 5 is a vertical sectional view of a
detail;
Figure 6 is a horizontal sectional view
another detail;
Figure 7 is a sectional view of another
detail.
Tel qu'il est représenté aux Figures 1 à 3, l'appui-tete 1 est monté pivotant autour d'un axe horizontal 2 sur les extrémités libres de deux tiges 3a et 3b qui sont articulées autour d'un axe 4 par rapport à l'armature du dossier 5 du siège; cette armature porte deux grilles 6, mobiles transversalement et munies de crans dans lesquels peuvent s'engager les tiges 3a et 3b et qui permettent ainsi de verrouiller ces tiges dans la position angulaire choisie.As shown in Figures 1 to 3, the headrest 1 is pivotally mounted about a horizontal axis 2 on the free ends of two rods 3a and 3b which are articulated around an axis 4 relative to the frame of the seat back 5; this frame carries two grids 6, transversely movable and provided with notches in which the rods 3a and 3b can engage and which thus make it possible to lock these rods in the chosen angular position.
L'appui-tete 1 présente la forme générale d'un U dont les branches 7a et 7b sont reliées l'une à l'autre par une partie comportant un renflement 7c qui est dirigé vers l'avant lorsque les branches 7a et 7b sont verticales et dirigées vers le bas. En dessous du renflement 7c la partie de l'appui-tete reliant les branches 7a et 7b est arrondie comme on le voit en 7d. A leur extrémité, les branches 7a et 7b comportent des rainures 8a et 8b dans lesquelles peuvent s'engager les tiges 3a et 3b. The headrest 1 has the general shape of a U whose branches 7a and 7b are connected to each other by a part comprising a bulge 7c which is directed forward when the branches 7a and 7b are vertical and directed downwards. Below the bulge 7c the part of the headrest connecting the branches 7a and 7b is rounded as seen in 7d. At their end, the branches 7a and 7b have grooves 8a and 8b in which the rods 3a and 3b can engage.
A la Figure 1, les branches 7a et 7b sont sensiblement verticales et le bourrelet 7c est dirigé vers l'avant; les tiges 3a et 3b sont engagées dans les rainures 8a et 8b. L'appui-tete joue son rôle habituel.In Figure 1, the branches 7a and 7b are substantially vertical and the bead 7c is directed forward; the rods 3a and 3b are engaged in the grooves 8a and 8b. The headrest plays its usual role.
En le faisant pivoter de 900 dans le sens contraire à celui des aiguilles d'une montre, on peut amener l'appui-tete dans la position de la Figure 2.By rotating it 900 anti-clockwise, you can bring the headrest into the position of Figure 2.
L'utilisateur peut alors engager sa tete entre les branches 7a et 7b qui servent d'appuis latéraux, contre la branche qui les relie et forme appui arrière.The user can then engage his head between the branches 7a and 7b which serve as lateral supports, against the branch which connects them and forms rear support.
L'appui-tete évite alors au passager, en état de somnolence, que sa tete bascule dans les virages. The headrest then prevents the passenger, in a state of drowsiness, from having his head tilted when cornering.
Dans le mode de réalisation des Figures 4 à 7, l'appui-tete 9 comprend un appui arrière 10 et deux appuis latéraux 11.In the embodiment of Figures 4 to 7, the headrest 9 comprises a rear support 10 and two lateral supports 11.
Chaque appui 11 comporte une armature 12 qui est montée pivotante autour d'un axe vertical 13 sur un support 14.Each support 11 comprises a frame 12 which is pivotally mounted about a vertical axis 13 on a support 14.
Celui-ci comporte un patin 15 monté coulissant dans un rail 16 solidaire de l'armature 17 de l'appui arrière 10.This comprises a shoe 15 mounted to slide in a rail 16 secured to the frame 17 of the rear support 10.
t'armature 12 porte un ressort 18 qui peut s'engager dans des crans d'une crémaillère 19 solidaire du support 14. De son côté ce dernier présente sur sa face arrière des crans 20 pouvant s'engager, en position avant et arrière du support dans un crantage de l'armature 17 de l'appui arrière.the frame 12 carries a spring 18 which can engage in notches of a rack 19 secured to the support 14. For its part, the latter has notches 20 on its rear face which can engage, in the front and rear position of the support in a notch of the frame 17 of the rear support.
Chacun des appuis latéraux 11 peut ainsi être déplacé horizontalement entre une position arrière inactive et une position avant active, en étant immobilisé par le cran 20 dans chacune de ces positions. Lorsqu'il est en position active, on peut régler l'écart entre lui et la tête de l'utilisateur en le faisant pivoter autour de l'axe 13; le ressort 18 engagé dans un cran de la crémaillère 19 le maintient dans la position angulaire choisie.Each of the lateral supports 11 can thus be moved horizontally between an inactive rear position and an active front position, by being immobilized by the notch 20 in each of these positions. When in the active position, the distance between him and the user's head can be adjusted by rotating it around the axis 13; the spring 18 engaged in a notch of the rack 19 maintains it in the angular position chosen.
I1 va de soi que la présente invention ne doit pas être considérée comme limitée aux deux modes de réalisation décrits et représentés, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the two embodiments described and shown, but on the contrary covers all variants thereof.
