Description

Title of the invention: Mattress for an articulated bed, and articulated bed equipped with said mattress

[0001] Articulated and tilting beds are beds that allow for various postures thanks to a slatted base that can be articulated in one or more positions, thus facilitating user comfort. The slatted base's joints allow for different postures, such as, for example, different positions of the torso, lower limbs, lumbar region, cervical region, etc. The bed has a corresponding mechanism to allow the transition from one position to another. The mechanism consists of one or more articulation points in the transverse direction, that is, transversely to the longitudinal direction of the bed. As a result, the longitudinal direction of the bed is parallel to the anatomical longitudinal axis of the bed user in the intended position of use.In single beds, the bed dimension in the longitudinal direction is larger than in the transverse direction, as is also the case in beds for two users of classic dimensions ("double" or "two-seater", "queen size", "king size"), with the exception of the "presidential king size" format in which the longitudinal and transverse dimensions coincide (200 x 200 cm).

[0002] Since the mattress must be able to "follow" the bed base in the various positions defined by the rotation of the different transverse axes of articulation, the solution proposed by manufacturers focuses on mattresses made of materials that allow for good adaptability, such as latex, for example, and with moderate thicknesses, since greater thickness reduces adaptability. The problem with these highly adaptable mattresses of reduced thickness lies in their lower firmness. However, users generally prefer mattresses with a firmness greater than that which can be obtained with latex. This is why adjustable beds remain inconvenient for a significant number of users.

[0003] One objective of the present invention is to provide a means to address the aforementioned problem.

[0004] More particularly, the present invention proposes a mattress having a generally elongated parallelepiped-shaped body defining a length along the longitudinal direction and a width or transverse direction perpendicular to the longitudinal direction, the mattress comprising an expanded component that covers the entire length of the mattress, characterized in that said expanded component has cutouts along the transverse direction and that pass through the entire component in said transverse length on at least one face, intended to facilitate folding the mattress along an axis parallel to said transverse length.

[0005] Therefore, the invention provides mattress components made of expanded material, said component covering the longitudinal dimension of the mattress and having cutouts on one or both faces, perpendicular to said faces, intended to improve its adaptability to the articulated bed frame on which it rests. The component may be, for example, the core, a layer of padding, or a cross member of a fairing block, for example.

[0006] Finally, the present invention proposes a profile of a component or components of expanded mattresses that extend along the mattress specifically designed to allow expansion (and compression) in areas of the sleeping surface that absorb the greatest curvature when the base of an articulated bed articulates.

[0007] Preferably, the aforementioned expanded component also covers the entire transverse direction of the mattress. Preferably, this component is a core. In a preferred embodiment, the aforementioned core is composed of various materials.

[0008] In order to effectively absorb the curvature, preferably, the present invention features parallel cutouts on both faces of the core, since in an articulated bed the headboard usually adopts a concave position while the footboard has a convex surface. Thus, in certain embodiments, the component has cutouts on its lower surface in the headboard area and cutouts on its upper surface in the footboard area.

[0009] Preferably, the cutouts are arranged in groups of parallel cutouts grouped into zones. To accommodate the different curvatures permitted by the articulated bed, the cutouts in one zone differ in depth and / or density from those in another zone. Preferably, the cutouts are specifically designed to optimize the mechanical behavior of the expanded material, where applicable, a compression or tension zone. Preferably, within each zone, the distance between the cutouts and / or their depth can vary. For example, preferably, the depth of the cutouts can be greater at the center of each group of parallel transverse cutouts and smaller at the ends of the group. Similarly, the depth of the cutouts between zones can vary. In particular, for example, the depth of the cutouts on the upper face can be different from the depth of the cutouts on the lower face.

[0010] Insofar as the cutouts do not contribute to the adaptation of the mattress to the movements of the articulated bed, preferably the component (core or other) is devoid of them in the longitudinal direction.

[0011] The present invention also relates to articulated beds which include a mattress according to the present invention, in any of the proposed forms. Preferably, the groupings of cutouts coincide with a transverse axis of articulation of the bed.

[0012] For better understanding, by way of explanatory examples, but without limitation, drawings of an embodiment of the object of the present invention are provided in the appendix.

[0013] Fig. 1 represents a side view diagram of an articulated bed according to the present invention with a mattress according to the present invention.

[0014] Fig. 2 represents a perspective view of the mattress shown in Fig. 1.

[0015] Figure 1 represents an articulated bed 2 which is provided with two articulation axes 21, 22 transverse to the longitudinal direction. The bed is represented schematically only, without all of its components being shown. The head area is indicated by the reference numeral 23 and the foot area by the reference numeral 24. On the platform of the articulated bed is placed a mattress 1, of which only the core is shown, consisting of two layers 11, 12 of expanded material with different properties. Each layer occupies the entire dimension of the mattress, in both the longitudinal and transverse directions. The mattress 1 shown in the example has transverse cutouts for better adaptation of the mattress to the action of the articulated bed. The transverse cutouts are arranged in two groups. The first group of cutouts 14 is located on the underside of the mattress 1 and the second group of cutouts 13 is located on the upper side of the mattress 1.The first group of cutouts corresponds to the head area 23, while the second group of cutouts corresponds to the foot area 24. Both areas coincide with one of the articulation axes 21, 22. As can be seen, the depth of the cutouts differs in the two areas. Within each area, the density and / or depth of the cutouts also varies, due to the fact that the stretching required for the correct adaptation of the mattress to the position adopted by the adjustable bed varies with proximity to the articulation axis.

[0016] Figure 2 shows the core of mattress 1 of Figure 1 in its normal position, without being folded by an articulated bed. It can be seen that the cutouts extend over the entire transverse dimension of the mattress (1) (the same is true for the first grouping 14 and for the second grouping 13).

[0017] If the invention has been presented and described with reference to embodiments thereof, it is understood that these embodiments are not limiting to the invention, and that numerous variable construction details or other details may become apparent to a person skilled in the art upon interpretation of the description, claims, and drawings. All variants and equivalences included in the The scope of the present invention can therefore be considered as falling within the broader scope of the following claims.
