EP2022372A1 - Slatted frame with lumbar support - Google Patents

Abstract

Slatted frame comprises a frame (1) with slats (3) and a lying region (5) corresponding to the lordosis region of a person so that high compression of a mattress in this lying region is achieved with uniform loading of the mattress. Preferred Features: The slats of the lying region are partially raised compared with the lying regions next to the lying region.

Description

The invention relates to a slatted frame with lumbar support. The lordosis is the curvature of the spine between the cervical vertebrae area and the lumbar vertebrae, which is present in a healthy person and is directed downwards (forward convex). Support i. a curvature replicating support while sitting is perceived by many people as pleasant, so that in the meantime many seats in vehicles have built a so-called lumbar support.

In the case of known slatted frames, it is at most provided to change the compliance of the slats in an area-dependent manner with respect to the adjacent slats so as to produce in certain areas a lying sensation which is different from the remaining areas and thus beneficial to the person lying.

From the DE 197 46 156 B4 For example, it is known to equip the slats of a slatted base by means of lowerable fitting parts in order to be able to lower the slats of one area in relation to those of adjacent areas.

However, it has been shown on the basis of extensive investigations that the lying sensation, which is possibly achievable with the conventional systems by means of adaptation, is insufficient to achieve a lying-down behavior, especially in the lordosis area, which is perceived as optimal for most persons, especially in the supine position.

Thus, the invention has for its object to provide a slatted frame, which provides improved comfort, and which is inexpensive and easy to manufacture. This object is achieved by the reproduced in claim 1 slatted frame. Advantageous embodiments are the subject of the dependent claims. The independent claim relates to an advantageous arrangement of a mattress and a slatted frame.

The invention relates to a slatted base for a mattress with a frame and a plurality of slats mounted on the frame. Preferably, the plurality of slats are mounted transversely to the intended direction of lying and parallel to each other on the frame to define a support surface for a mattress. The slatted base according to the invention is characterized in that at least one slat and / or its storage of a certain lying area of the slatted frame predetermined lying surface is designed so that with uniform load on the mattress over the bed, for example, resting on the lying surface of the mattress plate, a higher compression of the mattress is achieved in this lying area, as in adjacent lying areas. According to the slatted frame is intended for a mattress. Mattresses are generally upholstery, which is placed on the slatted frame according to the invention, to allow a person a comfortable lying and sleeping. The invention is not limited with regard to the mattress. Thus, it may be, for example, a foam core, innerspring, latex core or natural mat filled mattress.

According to the invention, the lying area is an area of the lying area which is arranged in the region of the lordosis of a person lying on the mattress or corresponds to this area. As already mentioned, the lordosis is the curvature of the spine between the cervical vertebrae area and the lumbar vertebrae area, which is present in a healthy person (forward convex). In this assignment of the specific lying area to the lordosis area of a reclining person, a proper use of the slatted frame or the mattress and an average height of the person lying are assumed. Thus, in one embodiment, a person lying in the transverse direction is assumed, and a higher compression only in a transversely central region in comparison with in transverse and reached in lying direction adjacent areas. In a preferred, because no transverse lying median lying position for achieving the higher compression and thus support is assumed, this is caused over the entire transverse direction. This comparatively higher compression causes a particularly pronounced support of the spine in the lordosis area and provides for most people a very pleasant reclining sensation. The higher compression provides for a lying person for support in the lumbar region, for example, inter alia, by a lordosis corresponding increase in the upper surface of the mattress in this area.

In a further advantageous embodiment, the lath or slats of the specific lying area are at least partially arranged higher at least in the unloaded state compared to the arrangement of the slats of the adjacent or even remaining lying area. As a result, the inventive comfort-enhancing effect is achieved particularly easy. For example, the batten or the slats has a longitudinally upward curvature and is or are arranged so that it is or are at least partially elevated compared to the adjacent slats.

This elevation in the lumbar region in one half of the lying surface also has the advantage that it can be easily distinguished from the foot of the slatted base on the basis of the elevation overhead. As a result, there is no need to specify the orientation of the slatted frame imprint on the slatted frame and / or the intended alignment of the load grate optionally when inserting the slatted base in a bed position falls particularly easy.

In an advantageous embodiment, it is provided that the storage of the lath or slats of the specific lying area comprises a vertical travel to the lying surface and at least a part of the spring travel, the slat or slats is higher in comparison to the arrangement of the slats of the remaining lying area is or are. As a result, a variable load-dependent adaptable and thus perceived as particularly pleasant, compared with higher compression in a specific lying area (lordosis area) is advantageously achieved. For example, the lower stop of the spring travel (spring-loaded state) is the bar the lumbar area at the same height with slats of the adjacent area or in the event that it is the battens of the adjacent area to spring-mounted, lowerable battens, for example, the lower stop of the bar or the slats of the particular area at the same height its upper stop (unloaded state).

In a further advantageous embodiment of the aforementioned embodiment, a means for at least partial blocking of the spring travel or to prevent jounce is provided in order to make an adaptive adjustment of the excessive arrangement of the lath or their jounce in the particular lying area, for example, the end user.

In a further embodiment, the fittings provided for supporting the slats on the frame of the slatted base on a frame fixed to the bearing block with at least one vertical receiving bore and a slat holder with an insertable into the receiving bore pin. Such storage is for example from the DE 197 46 156 B4 which is hereby incorporated herein by reference.

Preferably, at least the bearing blocks of all hardware parts are the same design to reduce manufacturing costs.

In a further embodiment leaf springs are provided, which act to provide a spring travel on the free ends of the pins of the bar holder. For example, these are made of plastic to reduce the cost.

In a further embodiment, a plurality, for example three, offset in height mounting positions for the bearing block are provided on the frame to selectively fix the bearing block to it. As a result, a height adjustment and thus individual adaptation of the specific lying area to the individual lordosis area, or its lengthwise extension of the lying person or the amount of compression in this particular lying area, can be undertaken.

The invention relates to a remote arrangement of a mattress and a slatted frame in one of the previously described embodiments with the respective advantages associated therewith.

FIG. 1 On the frame 1 are several parallel to each other and transverse to the direction of lying slats 3, 3 ', 3 "(for clarity, not all slats are denoted by reference numerals) are provided, which are distributed over the bed surface On the lying surface defined by the slats 3, 3 ', 3 ", a mattress 2 is placed. The slats 3 ', 3 "are resiliently mounted in the bearing blocks 4' and 4". This makes it possible to lower the slats relative to the illustrated upper stop (rebounded state) of the spring travel of the slats 3 ', 3 "The slats 3 are likewise resiliently mounted on the bearing blocks 4 by means of the bearing 7. Opposite the adjacent slats 3', 3 However, "they are arranged so that their upper and illustrated (rebounded state) stop above the slats 3 'and 3" is located .Thus, with even load on the mattress 2 on the bed in the area of the arrowhead 5, a higher compression of the Generally elastic or viscoelastic mattress (2) as in the adjacent areas, here in the by the bearing blocks 4 ', 4 "predetermined lowering ranges achieved. This region of higher compression is arranged according to the invention in the region of the lordosis of a person lying down (not shown). This higher compression can provide an unobstructed mattress 2 for a bulge 6 of the mattress surface 2 in this area or provide a burdened by a lying person mattress 2 for a contour tracking of the bed surface and thus support the lumbar region.

In FIG. 2 Details of storage are shown. On the ends of the slats 3, 3 'cap-shaped holding elements 10, 10' attached. On the holding elements 10, 10 'pins 9, 9' are formed, which are respectively inserted in vertical through holes of the bearing blocks 4, 4 '. The length of the pins 9, 9 'defines in each case a spring travel. This upwardly directed spring effect is caused in each case by a leaf spring 8, 8 'provided on the respective bearing block 4, 4', which acts on the free end of the pin 9, 9 " 3 in the illustrated rebound condition and when jouncing above the height of the batten 3 'until it reaches the height of the rebounded, illustrated state of the batten 3', which is outside the lumbar region, in the fully rebound condition The aforementioned lumbar support is achieved in order to prevent deflection of the slat 3, optionally an element 11 can be attached to the journal 9 in order to hinder the compression or to at least partially block the suspension travel.
