Un tel sommier donne entière satisfaction du point de vue confort lorsque la partie relevable est en position horizontale, mais au fur et à mesure que cette partie est relevée apparaít une sensation d'inconfort au niveau de la zone d'assise définie par la partie formant dossier du fait que les lattes de cette zone d'assise s'enfoncent de plus en plus sous le poids de l'utilisateur du sommier.Such a box spring gives complete satisfaction from the point of view comfort when the liftable part is in position horizontal, but as this part is raised appears a feeling of discomfort in the seating area defined by the backrest part of the causes the slats in this seating area to sink more and more under the weight of the user of the box spring.
Pour éviter le problème d'enfoncement exagéré des lattes en position assise, des solutions ont été proposées consistant toutes à renforcer la fermeté de la zone fessière en utilisant des lattes de raideur plus élevée, des lattes supplémentaires, avec ou sans curseurs de réglage de fermeté. Cependant, ces solutions connues ont pour inconvénient de rendre le sommier inconfortable et trop ferme en position allongée de repos de l'utilisateur.To avoid the problem of excessive sinking of the slats solutions have been proposed while seated all consisting in strengthening the firmness of the area gluteus using higher stiffness slats, additional slats, with or without sliders firmness adjustment. However, these known solutions have for the disadvantage of making the box spring uncomfortable and too firm when lying down the user.

La figure 7 est une vue en perspective suivant la flèche VII de la figure 2.Figure 7 is a perspective view along the arrow VII of figure 2.
En se reportant aux figures, la référence 1 désigne un
sommier du type à lattes transversales 2 disposées
transversalement au cadre en bois 3 du sommier qui
comprend une partie relevable 4 constituée d'un cadre
métallique portant des lattes transversales 2 et pouvant
occuper une position rangée horizontale dans le cadre 3
du sommier et plusieurs positions relevées inclinées
sélectivement réglables par l'utilisateur de façon à
constituer un dossier. Referring to the figures, reference 1 designates a
bed base of the type with
Le déplacement de la partie relevable 4 est commandé par
un moteur électrique 5 fixé dans le cadre 3 du sommier à
l'un des longerons 6 de celui-ci. Le moteur électrique 5
est activé par une commande manuelle (non représentée)
reliée à celui-ci par un cordon électrique. Le moteur
électrique 5 a son arbre moteur 7, disposé
transversalement entre les longerons 6 du cadre 3 du
sommier, qui est accouplé mécaniquement à la partie
relevable 4 par des bras latéraux 8 permettant le
pivotement autour de l'axe défini par l'arbre moteur 7 de
la partie relevable 4.The movement of the lifting part 4 is controlled by
an
Selon l'invention, la fermeté de la zone d'assise des
lattes 2 définie par la partie 4 occupant une position
relevée formant dossier est automatiquement changée en
fonction du pivotement de la partie relevable 4.According to the invention, the firmness of the seating area of the
A cet effet, le dispositif permettant de changer la
fermeté de cette zone d'assise comprend une pièce rigide
en forme de plaque 9, de préférence métallique et
rectangulaire, disposée sous les lattes 2 de la zone
d'assise et pouvant être déplacée de façon guidée
relativement au cadre 3 du sommier entre une position
inférieure représentée aux figures 2 et 4 à laquelle les
lattes 2 de la zone d'assise peuvent se débattre
librement sous le poids de la personne et une position
supérieure représentée aux figures 3 et 5 limitant le
débattement des lattes 2 à une valeur correspondant à une
fermeté maximum de la zone d'assise.To this end, the device for changing the
firmness of this seating area includes a rigid piece
in the form of a
Ainsi, lorsque la partie relevable 4 occupe sa position
rangée horizontale dans le cadre 3 du sommier, les lattes
2 de la zone d'assise procurent à l'utilisateur allongé
sur le sommier, via un matelas, la sensation de confort
habituel du fait que le poids exercé à cette zone par le
fessier de l'utilisateur n'est pas très élevé. Au fur et
à mesure que la partie 4 est relevée vers sa position
relevée maximum, la pièce rigide 9 se rapproche des
lattes 2 de la zone d'assise de façon à limiter le
débattement de ses lattes et à empêcher que le poids de
plus en plus important de l'utilisateur se concentrant à
la zone fessière de celle-ci écrase les lattes.Thus, when the lifting part 4 occupies its position
horizontal row in
Le déplacement de la pièce rigide en forme de plaque 9,
suivant une direction perpendiculaire au plan du cadre 3
du sommier 1, est commandé par le moteur électrique 5
dont l'arbre moteur 7 est accouplé à la pièce rigide 9
par des moyens mécaniques de déplacement de celle-ci.The displacement of the rigid plate-
Ces moyens mécaniques comprennent deux barres rigides
métalliques et parallèles 10, 11 montées à rotation dans
le cadre 3 transversalement aux longerons 6 de celui-ci
et accouplées à l'arbre moteur 7 de façon à être
conjointement entraínés en rotation dans le même sens ;
et deux paires d'éléments formant came 12 ; 13 solidaires
respectivement des deux barres rotatives 10 ; 11 et
situés en dessous de la pièce rigide 9 de façon à
déplacer celle-ci perpendiculairement aux barres
rotatives 10, 11 lorsqu'entraínées conjointement par
l'arbre moteur 7. Chaque élément formant came 12, 13 est
réalisé à partir d'une plaque métallique fixée
perpendiculairement à la barre rotative de support
correspondante 10, 11. Chaque barre 10, 11 a chacune de
ses parties d'extrémité tubulaire montée tournante sur un
axe cylindrique 14 fixé perpendiculairement au longeron
correspondant 6, par exemple par une vis de fixation 15.These mechanical means include two rigid bars
metallic and parallel 10, 11 rotatably mounted in
the
Les moyens d'accouplement des barres rotatives 10, 11 à
l'arbre moteur 7 comprennent deux paires de biellettes
15, 16 comprenant chacune une biellette 17 de jumelage
des deux barres 10, 11 et reliées à ces barres par
l'intermédiaire de deux bras de levier 18 et une
biellette 19 de liaison de la barre rotative 10 à l'arbre
moteur 7 par l'intermédiaire d'un bras de levier 20
solidaire de l'arbre moteur 7. Chaque biellette 19 est
reliée à la barre rotative 10 par le bras de levier 18 de
liaison de la barre 10 à la biellette 17. Comme
représenté en figure 7, chaque axe d'articulation 21
reliant un bras de levier 20 à la biellette
correspondante 19 est logé dans une lumière ou trou
oblong 22 réalisée à l'extrémité de la biellette 19 et
permettant au moteur électrique 5, lorsque la pièce
rigide en forme de plaque 9 est en position basse,
d'avoir suffisamment de puissance pour soulever la pièce
rigide 9. Les trous oblongs 22 introduisent un retard
dans la levée de la plaque 9 et permettant de ne pas
augmenter trop rapidement la fermeté de la zone d'assise
si on ne lève que légèrement la tête et de ne pas
surcharger le moteur pendant la phase de début de levée
de la tête ou du torse, phase où le moteur est le plus
sollicité du point de vue puissance.The means for coupling the
Le guidage du déplacement de la pièce rigide 9 suivant la
direction perpendiculaire au plan passant par les barres
rotatives 10, 11 s'effectue par deux paires de pattes de
guidage 23, 24 fixées sous la pièce rigide 9
perpendiculairement à celle-ci, par exemple par
l'intermédiaire de vis de fixation, et engagées
respectivement sur les deux barres rotatives 10, 11 qui
traversent des trous oblongs 25, 26 respectivement des
pattes de guidage 23, 24 permettant à celles-ci de
coulisser perpendiculairement aux barres respectives 10,

Les paires de biellettes 15, 16, les paires d'éléments
formant came 12, 13 et les paires de pattes de guidage
23, 24 sont disposées symétriquement à l'axe longitudinal
du cadre 3 du sommier 1. The pairs of
Le fonctionnement du dispositif de l'invention ressort déjà de la description qui en a été faite ci-dessus et va être maintenant expliqué.The operation of the device of the invention is apparent already from the description that was made above and goes now be explained.
Lorsque l'utilisateur souhaite occuper une position
assise sur le sommier 1, il active le moteur électrique 5
de façon que l'arbre moteur 7 entraíne les deux bras de
levier 20 dans le sens des aiguilles d'une montre par
rapport à la figure 2. Chaque bras de levier 20 pousse
alors la biellette correspondante 19 vers la droite par
rapport à la figure 2 de façon à entraíner simultanément
en rotation, par la biellette 17 et les bras 18, les deux
barres 10, 11 dans le sens anti-horaire. Les éléments
formant came 12, 13 sont de la sorte entraínés en
rotation simultanément également dans le sens anti-horaire
comme indiqué par les flèches en figure 4 et
permettent le déplacement vertical vers le haut de la
pièce rigide en forme de plaque 9 en synchronisme avec le
pivotement de la partie relevable 4 vers sa position
relevée choisie. La descente de la pièce rigide en forme
de plaque 9 s'effectue en commandant le moteur électrique
5 de façon à déplacer les éléments formant came 12, 13
dans le sens inverse à celui indiqué par les flèches de
la figure 4, le mouvement de descente de la pièce rigide
9 s'effectuant par gravité ou sous le poids de
l'utilisateur. On notera que le poids de l'utilisateur,
qui est maximal lorsque celui-ci est assis avec la partie
4 relevée en position maximum, est efficacement supporté
pratiquement par les deux barres rigides métalliques 10,
11. De plus, en position haute maximum de la pièce rigide
9, les lattes 2 de la zone d'assise sont pratiquement en
contact avec celle-ci qui est de préférence capitonnée ou
rembourrée. When the user wants to occupy a position
seated on the base 1, it activates the
L'invention a été décrite en référence à un sommier à
moteur électrique de commande de pivotement de la partie
relevable 4, mais il est bien entendu qu'elle s'applique
également pour un sommier du type à partie relevable
formant dossier manoeuvrée manuellement. De plus, on
pourrait envisager de déplacer la pièce rigide en forme
de plaque de changement de fermeté de la zone d'assise du
sommier en manoeuvrant, par un mécanisme à bras de
levier, les paires de biellettes 15, 16 indépendamment du
pivotement de la partie relevable 4.The invention has been described with reference to a box spring
electric part swing control motor
liftable 4, but it is understood that it applies
also for a box spring of the lifting part type
forming a manually operated backrest. In addition, we
might consider moving the rigid piece into shape
of firmness change plate of the seat area of the
bed base by operating, by an arm mechanism of
