POCKET SPRING MATTRESS AND SLATTED BASE

Description

[0001] The present invention relates to a pocket spring mattress, preferably in combination with a slatted frame, which is used as a support device for a mattress. The mattress is characterized in that its spring firmness, particularly in the shoulder support area, can be easily adjusted. The mattress has a spring basket and at least one support, which can be exchanged individually or together to adjust the firmness of the mattress. The slatted frame is characterized in that it can be variably adjusted to a variety of heights and spring properties of the slats. The invention further relates to a mattress system with multiple spring baskets and supports, from which a combination of a spring basket and at least one support can be selected to produce a mattress tailored to the user's needs.

[0002] The slatted frame has the advantage that the slats are arranged in areas corresponding to the human body and slats only need to be moved within the slatted frame in order to adjust the height and spring properties.

[0003] Generally, the slatted frame has two end frame sections, preferably of the same length, which are pivotally connected opposite one another to a central frame section or which are rigidly connected to one another. Optionally, each of the end frame sections can be pivoted independently of the other on the central frame section, e.g., into a plane common to the central frame section or beyond the plane in which the central frame section lies, e.g., to pivot only one or both of the end frame sections, e.g., to pivot one or both of the end frame sections higher for the upper body or the legs, and optionally to further fix them in a pivoted position.In embodiments in which the end frame sections are rigidly connected to the central frame section, the central frame section can have a pivot joint about which the end frame sections can be pivoted towards one another, e.g. in order to arrange the end frame sections relative to one another, in particular for arranging the folded slatted frame in a package. Generally speaking, each pivot joint to which an end frame section is hinged is preferably arranged with its pivot axis on the side of the long sides opposite the slats. The long sides and their end frame sections can be formed from wooden beams, e.g. with a rectangular cross-section, or hollow metal profiles, each of which is subdivided in the region of a pivot joint.The long sides can be divided by having end faces arranged perpendicular to their length, or by having end faces arranged in a V-shape, with the pivot joint located in the area of ​​the smallest distance between the end faces. A pocket-spring mattress preferably rests on the slatted frame.

[0004] The invention further relates to a method for transporting a pocket-spring mattress according to the invention, which is arranged in an airtight cover, comprising the step of evacuating the cover, rolling up the cover with the pocket-spring mattress arranged therein, packing this rolled-up cover in a carton, and transporting the carton. Preferably, the end frame sections of a slatted frame according to the invention are pivoted toward one another along one or two pivot joints, then packing the slatted frame with the end frame sections pivoted toward one another in a separate carton, and transporting the frame.

[0005] DE 298 09 859 U1 discloses modular mattress systems that contain a single- or multi-part mattress core that can be connected to a topper and / or a plate. Furthermore, mattresses divided into zones of varying firmness are known from DE 297 10 758 U1, for example. The arrangement of the zones is usually symmetrical or synchronous.

[0006] The NZ 330983 A describes a mattress that has four firmness zones, each with exactly one shoulder zone, and forms the firmness of the mattress zones through the combination of foamed polyurethane or foamed latex with cylindrical recesses in which spiral springs are arranged.

[0007] EP 1 352 597 A1 discloses a spring mattress with a removable insert. US 2006 / 0185084 A1 discloses a mattress with a support frame.

[0008] The aforementioned types of mattresses have the disadvantage that after purchase, individual adaptation to the needs of the user is not possible or not possible in a simple way (e.g. only by exchanging the mattress).

[0009] DE 10 2015 101 432 B4 describes a slatted frame for supporting a mattress, which has curved spring slats on a frame and spring slats which have a flat, centrally arranged bridge area between end-positioned cranked sections, so that the bridge area is arranged higher or lower when these slats are turned.

[0010] The aforementioned types of mattresses have the disadvantage that after purchase, individual adaptation to the needs of the user is not possible or not possible in a simple way (e.g. only by exchanging the mattress).

[0011] It has been shown that conventional slatted frames allow only limited adjustment by varying the spring action and / or height of slats which, from one end of the slatted frame, have a head area, a shoulder area, an adjacent lumbar area, an adjacent pelvic area, a leg area and a foot area.

[0012] The object of the invention is to provide an alternative mattress that can be easily adapted to the user's needs. In particular, the mattress should be adjustable in its spring firmness, at least in certain sections, e.g., in the area where the shoulder rests, preferably allowing easy variation of the degree of firmness, particularly in the shoulder area. Preferably, the mattress is provided in combination with a slatted frame that allows a variety of adjustments of the slats with regard to their height relative to the frame and their spring action, in order to adapt the slatted frame to a body, wherein the slatted frame provides a general adjustment, particularly for the lumbar region.

[0013] The invention solves this problem with the features of the claims and, in particular, provides a pocket spring mattress that is arranged on the slatted frame with its upper side facing away from the mattress. The mattress is characterized in that its spring firmness, particularly in the shoulder support area, can be easily adjusted. The mattress has a one-piece spring basket and at least one pad, which can be replaced individually or together to adjust the firmness of the mattress. The invention further relates to the slatted frame in combination with a mattress system with several one-piece spring baskets and pads, from which a combination of one of the spring baskets and at least one pad can be selected to produce a mattress tailored to the user's needs, optionally in combination with a slatted frame.Preferably, the invention also relates to a method for adapting a slatted frame of a pocket spring mattress to a human body, wherein the slatted frame is rotated by 180° in the plane in which its frame extends and / or the slats (11) of one shoulder area are exchanged for the slats of the other shoulder area and / or the supports of one shoulder area are exchanged for the supports of the other shoulder area.The invention further relates to a method for producing a slatted frame in combination with a pocket spring mattress, in which the pocket spring mattress is composed of a mattress system which contains at least two spring baskets and at least three first supports, wherein a first of the at least two spring baskets has a first shoulder region with a first spring hardness and a second shoulder region with a second spring hardness, and a second of the at least two spring baskets has a first shoulder region with a third spring hardness and a second shoulder region with a fourth spring hardness, and wherein the at least three first supports each have different degrees of hardness.Furthermore, the method can provide that the spring basket is wrapped in a common cover together with the first and / or the second support, or alternatively that only the spring basket is wrapped in a cover and only a first support is applied to one side of the cover.

[0014] The pocket spring mattress has a one-piece spring basket having a first end and an opposite second end, wherein the distance between the first end and the second end of the spring basket is the length of the spring basket or the length of the mattress, a first side and an opposite second side, each connecting the first end to the second end, wherein the distance between the first side and the second side is the width of the spring basket or the width of the mattress, a top side and an opposite bottom side, wherein the distance between

[0015] Top and bottom are the height of the spring basket and the springs are spiral springs arranged with their spring axis parallel to the height of the spring basket, with the top being designed as a support surface and the bottom facing the slatted frame when the mattress is arranged on a slatted frame, wherein the spring cage is divided into zones arranged parallel to its width, wherein the spring cage has a first shoulder region of a first spring hardness and a second shoulder region of a second spring hardness, wherein the first spring hardness is different from the second spring hardness, a first support which adjoins the upper side of the spring cage and is preferably connectable to the latter, optionally a second support which adjoins the lower side of the spring cage and is preferably connectable to the latter, a cover in which the spring cage, the first support and / or optionally the second support are contained, preferably a strip steel which is arranged between a row of springs arranged adjacent to the circumference of the spring cage and a row of springs adjacent to this, on or consists of.

[0016] Preferably, the mattress has a support only on its upper side and consists of a spring basket which is wrapped in a cover and a support which is arranged inside, preferably outside the cover on the upper side of the mattress.

[0017] The spring basket is generally constructed in one piece, so that the individual zones cannot be removed separately from the spring basket. When the mattress is arranged on a slatted frame, the spring basket is generally arranged with its underside facing the slatted frame and its upper side facing away from the slatted frame, with only one support being preferably arranged on the upper side, within a cover enveloping the spring basket or on the outside of a cover enveloping the spring basket. In particular, the mattress is not reversible, i.e. it is not suitable for rotating about an axis of rotation parallel to the length and / or width of the spring basket and resting with the upper side, on which the first support is arranged, adjacent to a slatted frame.

[0018] Generally, pocket springs are arranged in the spring cage, with their spring axes aligned parallel to the mattress's rotation axis, which is parallel to the height of the mattress. Accordingly, the pocket springs are arranged with their spring axes perpendicular to the top and bottom of the mattress. The firmness of the spring cage, or the zones within the spring cage, is generally determined by the spring strength of the pocket springs arranged within it, with a lower degree of firmness being achieved by a lower spring strength, and a higher degree of firmness being achieved by a higher spring strength.

[0019] The spring basket has 7 zones, starting from its first end a first head area, a first shoulder area, a first lumbar area, a pelvic area, a second lumbar area, a second shoulder area and a second head area.

[0020] The rotation axis of the mattress is formed parallel to the height of the spring basket or perpendicular to the top. In general, the mattress can be transferred from a first position to a second position by rotating it 180° around the rotation axis, wherein in the second position the second shoulder area is preferably arranged exactly in the area in which the first shoulder area is arranged in the first position and vice versa, so that the second shoulder area takes the place of the first shoulder area and vice versa. For this purpose, the distance between the first end and the first shoulder area is preferably exactly the same as the distance between the second shoulder area and the second end, and the first and second shoulder areas each have the same dimensions.

[0021] It has been shown that the comfort of lying on a mattress is primarily determined by the firmness of the mattress in the shoulder support area, while the firmness in the leg area can be neglected. In the first position of the mattress, the user rests with their shoulder in the first shoulder area of ​​the mattress and their legs in the second shoulder area. By rotating the mattress 180° around the rotation axis, the mattress is transferred to the second position, in which the user rests with their shoulder in the second shoulder area of ​​the mattress and their legs in the first shoulder area of ​​the mattress.

[0022] According to the invention, the first head region has the same degree of hardness as the second head region. Furthermore, the first lumbar region has the same degree of hardness as the second lumbar region. However, by way of derogation from this, the first shoulder region according to the invention has a degree of hardness that is higher or lower than the second shoulder region, e.g. higher or lower by at least 10% or by at least 20%, e.g. in each case up to 30% or up to 25%, measured as the average spring strength of the springs contained therein. According to the invention, a lower degree of hardness is achieved in that the springs have a smaller diameter and are made of spring wire of the same thickness and hardness as springs in a region with a higher degree of hardness. All springs are spiral springs whose spring axes are arranged parallel to the height or perpendicular to the top of the spring basket.In general, all springs, in particular adjacent springs, are preferably arranged with their spring axes at the intersection points along the same lines running parallel to the length and width of the spring cage, so that the springs of smaller diameter are arranged at a greater distance from one another in the width of the spring cage. Further preferably, all springs, in particular adjacent springs, are arranged with their spring axes along the same lines running parallel to the length of the spring cage, wherein the springs are further preferably arranged with their pockets adjacent to one another along their circumference and / or in contact with one another. The regions of the pockets that are arranged in contact with one another can be connected to one another, e.g. glued, or unconnected and only loosely contact one another. In general, adjacent springs are arranged with their spring axes at the intersection points of the same lines orarranged in exactly one grid of lines that run parallel to the length and width of the spring cage, with all springs arranged without offset to neighboring springs, or no springs arranged with an offset to neighboring springs.

[0023] By having the same degree of hardness in the first and second head areas, or the first and second lumbar areas, the mattress has the advantage that by rotating around the axis of rotation only the degree of hardness of the shoulder area can be varied and the other zones of the mattress, in particular in the lumbar and pelvic areas, have essentially the same degree of hardness in the second position as in the first position.

[0024] According to the invention, the spring cage has a circumferential steel strip which is arranged between a row of pocket springs arranged adjacent to the circumference of the spring cage and a row of pocket springs adjacent to this, such that the steel strip runs parallel to the circumference of the spring cage and is spaced from the circumference of the spring cage by exactly the outer row of pocket springs. The steel strip has a rectangular cross-section, wherein its broad side is preferably arranged parallel to the upper side, and more preferably the steel strip is arranged adjacent to the upper side or in the plane of the upper side. The steel strip has, for example, a broad side of 5 to 20 mm, preferably 10-15 mm, and a thickness of 1 to 4 mm, preferably 2-3 mm. Generally speaking, the steel strip is preferably made of spring steel. A steel strip arranged in this way allows the spring cage to be rolled up around an axis lying parallel to the upper side, parallel to the width or perpendicular to the length of the spring cage, e.g.B. for arranging the rolled-up spring basket in a box. Additionally, the steel strip provides the spring basket with sufficient stability, e.g., to prevent the top from shifting toward the bottom of the spring basket. Optionally, the spring basket is only covered by a cover, which can consist of a single layer of fabric. Furthermore, the steel strip provides sufficient strength to the spring basket's edges, e.g., to prevent a person sitting on the edge from sinking excessively.

[0025] The first layer, also referred to as the topper, preferably comprises or consists of foamed natural latex or foamed 100% natural latex, optionally in a cover. The first layer is preferably designed to rest completely on the top surface of the spring cage and is the same length and width as the spring cage.

[0026] The first layer has a firmness level that is preferably constant across its entire cross-section. The first layer is preferably designed so that its firmness level, in combination with the spring basket and optionally additional layers, results in an overall mattress firmness of H1, H2, H3, H4, or H5.

[0027] The optional second support may comprise or consist of foam and / or comprise or consist of an elastic wall. Preferably, the second support is configured so that the spring cage rests on it over its entire surface and has the same length and width as the spring cage.

[0028] Generally speaking, the mattress, including the spring basket, cover and one layer or first layer and optionally an additional second layer, is free of adhesive.

[0029] Generally, the spring basket is encased in a cover, optionally together with the first and / or second support, or alternatively individually or separately from the first and / or second support. When the mattress is placed on a slatted frame, the cover rests on top, preferably directly on the slatted frame.

[0030] The spring basket, preferably the cover, is generally preferably designed to be connected to the first and / or second support, e.g. by means of hook-and-loop fasteners or zippers, the closure halves of which are each arranged to fit on mutually facing sides of the spring basket or the cover and the first or second support. Optionally, the spring basket in the mattress is only connected to the first and / or second support in that the spring basket, first support and optionally second support are contained in a common cover, in particular are not glued. Preferably, the mattress consists of a spring basket which is wrapped in a cover, on one side of which, which forms the upper side, a support is arranged and connected to the cover, and is in particular free of adhesive. The support, which is generally also referred to here as the first support, can be connected to the cover only by means of a hook-and-loop fastener and / or a zipper.

[0031] The mattress system comprises at least two spring baskets and at least three first supports, and optionally at least two second supports. In general, a first of the at least two spring baskets comprises a first shoulder region with a first spring hardness and a second shoulder region with a second spring hardness, and a second of the at least two spring baskets comprises a first shoulder region with a third spring hardness and a second shoulder region with a fourth spring hardness, wherein the first, second, third, and fourth spring hardness preferably differ by at least 10% or at least 20%. Furthermore, the at least three first supports each have different degrees of hardness. Preferably, the at least three supports all have the same height. Optionally, the at least two second supports each have different degrees of hardness, different thicknesses, or are made of a filling made of different materials, e.g.one made of foam, one made of animal wool, one made of cotton, one made of synthetic fibers, each in a cover made of, for example, cotton fabric.

[0032] Preferably, first supports which have different degrees of hardness and / or consist of a shell with a filling made of different materials all have the same height or thickness.

[0033] To produce a mattress from the mattress system, preferably exactly 1 spring basket, exactly 1 first layer, optionally exactly 1 second layer is selected from the mattress system and the spring basket, optionally together with the first and / or the second layer, is wrapped in exactly one common cover, or exactly one layer, also referred to as the first layer, is arranged on top of the cover that only wraps the spring basket.

[0034] It has been shown that an optimal lying feeling on a mattress can be created by the interplay of the overall firmness of the mattress. In this case, a mattress basket with spring firmness is selected for the body weight and height of the user. This mattress basket has a suitable spring firmness in the first shoulder area and a spring firmness that is one degree softer or harder in the second shoulder area. By combining two shoulder areas whose spring firmnesses differ by exactly one degree, the degree of firmness can be varied or changed by one degree by simply rotating it around the axis of rotation. According to the invention, by selecting a first layer and a spring basket, optionally a second layer, a mattress can be produced from the mattress system that creates an optimal lying feeling and contains a variation in the degree of firmness in the shoulder area.The mattress has the advantage that in order to vary the degree of firmness in the shoulder area, the springs of the spring basket remain unchanged and do not have to be replaced segment by segment, for example.

[0035] The mattress is positioned with its pelvic area to match the pelvic area of ​​the slatted frame, so that the shoulder areas of the mattress are also positioned to match the shoulder areas of the slatted frame and the lumbar areas of the mattress are positioned to match the lumbar areas of the slatted frame.

[0036] The invention further relates to a slatted frame in combination with the pocket spring mattress, with slats arranged parallel to each other and spaced apart for placement under a mattress, the a rectangular frame with long sides and end narrow sides, wherein the frame has or consists of a central frame section and a first end frame section and a second end frame section pivotably connected thereto or rigidly connected thereto and opposite one another, optionally only the central frame section has a pivot joint, wherein generally preferably the second frame section is pivotally connected to the first frame section, wherein the long sides of the end frame sections and the central frame section are preferably arranged at the same distance from one another, optionally the frame is arranged on a second frame, wherein the end frame sections are pivotable relative to the second frame and can be fixed in a pivot position, wherein more preferably the second frame is rigid, slats arranged parallel to the narrow sides,whose ends have the same cross-section and are held by supports fixed to the frame, wherein preferably two adjacent slats are held by their ends in a common support, wherein 12 slats are arranged on the first and second end frame sections, of which the two slats that are immediately adjacent to the respective end narrow side form an end region, four slats that are immediately adjacent to the central frame section form a lumbar region, and six slats that are arranged between the end region and the lumbar region form a shoulder region, wherein the slats that form the shoulder region on the first end frame section are held by height-elastic supports, the slats that form the shoulder region on the second end frame section are held by non-elastic, preferably height-adjustable supports,wherein the slats of one shoulder region are preferably bent between their ends and their middle section and the slats of the other shoulder region have, at least in their middle section, a central elongated hole parallel to the longitudinal extension of the slat, wherein the 4 slats forming the lumbar regions are adjustable in their spring action and are held on height-adjustable supports, wherein 4 slats forming the pelvic region, which preferably extends over the central frame section, are adjustable in their spring action and are held on non-height-adjustable, optionally springy supports, wherein preferably each slat which is immediately adjacent to the respective end narrow sides of the frame has a projection facing the end narrow sides, which projects beyond the cross-section of its ends, wherein preferably the supports which each have one slat, optionally two slats,which are immediately adjacent to the respective end narrow sides of the frame, are held in exactly one position relative to the frame or are not height-adjustable relative to the frame, has or consists of.

[0037] The slatted frame is based on the realization that a central frame section, which forms a pelvic area, can be arranged between two end frame sections, and that each of the end frame sections can have a different combination of supports and slats held therein in order to configure one of the end frame sections to a desired shoulder area, while the shoulder area of ​​the other end frame section is sufficiently adjustable or adapted as a leg area. The slatted frame therefore offers a shoulder area in each end frame section, so that when aligned horizontally, the slatted frame already offers two different interchangeable shoulder areas by rotating it horizontally. Furthermore, the supports and slats of the shoulder areas can be freely combined, e.g. by exchanging supports and / or slats from the second shoulder area for supports and / or slats from the first shoulder area.It has been shown that the individual adjustment of the slatted frame to a body is significantly more important in the shoulder area than in the leg area, and that the supports and slats arranged in the non-adjusted shoulder area always form an acceptably adjusted leg area. The slatted frame according to the invention forms two lumbar areas that can be freely combined with the other areas, in particular with the shoulder areas. It has been found that the lumbar areas can each be held by four identical slats with adjustable spring action on height-adjustable supports, each springy or non-springy, and a centrally arranged pelvic area, which extends over four slats, can have slats with adjustable spring action on non-height-adjustable supports.

[0038] In general, slats adjustable in their spring action are preferably formed by two parallel bent slats arranged one above the other, which are clamped against each other by at least two clamping elements displaceable along the slats, wherein preferably only the ends of one of the slats are held in a support and the other, parallel slat is shorter.

[0039] Non-spring slats are solid, one-piece slats that have an arched central section or are completely arched, optionally with a bend between their arched central section and their ends.

[0040] The slats of one shoulder area, which are bent between their ends and their central section, can have a curved central section, particularly one that is convexly curved towards the area on which a mattress is placed, or a central section that is flat when not under load. Generally, these slats are bent in opposite directions between their ends and their central section, so that the ends are spaced in a common plane from the plane in which the central section extends. Such slats can be held by the supports in a position rotated 180° about their longitudinal axis in order to arrange their central section in a different plane, e.g., relative to the plane in which the slats of the pelvic area extend.

[0041] Non-height-adjustable supports are supports that hold slats at exactly one height, optionally spring-loaded, on the frame and, for example, supports that have exactly one mounting section, so that the recess in the support in which one end of a slat is held is arranged at exactly one distance from the frame.

[0042] Height-adjustable supports have at least two preferably parallel mounting sections, so that their recess, in which one end of a slat is held, is arranged at one of at least two distances from the frame, depending on the mounting section which is connected to the frame.

[0043] Spring supports are made of plastic and have at least one spring section between their recess, into which one end of a slat can be inserted and held, and a mounting section that can be connected to the frame. The spring section can, for example, have at least two spring arms, e.g. at least four spring arms arranged around a hollow space. A mounting section can be designed for the arrangement of a plug-in connection, clamp connection or screw connection that is fixed to the frame. Preferably, the mounting section is designed for the arrangement of a plug-in connection that can be reversibly connected to the frame, e.g. holes for receiving bolts that are fixed to the frame. Spring supports are, for example, those with a change in the distance between the recess, in which one end of a slat is held, and the mounting section by at least 1 cm, preferably by at least 2 cm or at least 3 cm, under a load of 100 N (approximately 10 kg).

[0044] Non-resilient beams are those in which there is a substantially rigid connection without a spring element between the mounting section and the recess in which one end of a batten is held, e.g. with a change in the distance between the recess in which one end of a batten is held and the mounting section by a maximum of 1 cm, preferably by a maximum of 0.5 cm or a maximum of 0.2 cm by a load of 100 N (about 10 kg).

[0045] In general, a middle section of a batten can have 50 to 80% of its length between the supports.

[0046] Slats which have a central elongated hole parallel to the longitudinal extension of the slat in their central section can consist of two, three or four parallel narrow slats, the distance between which forms a elongated hole which optionally extends over the entire length between the supports, wherein the narrow slats are preferably connected to one another at their ends.

[0047] The second frame is preferably congruent with the frame if its frame sections are arranged in a common plane, and is particularly arranged below the frame opposite the direction of pivoting of the end frame sections. Optionally, a second frame can circumferentially surround the first frame. In embodiments in which the frame sections are rigidly connected to one another, the longitudinal sides of the frame can be formed as a single piece.

[0048] Preferably, the slatted frame has exactly one frame consisting of two parallel long sides and end narrow sides attached to them, wherein the long sides are divided in the middle and connected with a hinge.

[0049] The slatted frame will now be described in more detail with reference to the figures shown schematically in Fig. 1 a design of the slatted frame in top view, Fig. 2a design of the slatted frame in side view, Fig. 3 a view of an embodiment of the spring cage, Fig. 4 a design of the mattress in longitudinal section and Fig. 5a, b show a section of a long side with a preferred pivot joint for two sections of a long side of a slatted frame.

[0050] In general, the same reference numbers in the figures indicate elements with the same functions.

[0051] The Figure 1shows a slatted frame with a rectangular frame 1 with long sides 2 and end narrow sides 3, which form a central frame section 4 and, pivotally connected thereto, a first end frame section 5 and, opposite, a pivotally connected second end frame section 6. The long sides 2 of the end frame sections 5, 6 and the central frame section 4 are arranged at the same distance from one another, so that supports 7 attached thereto, which are opposite one another, are at the same distance from one another and all slats have their ends at the same distance, so that all slats can be exchanged between the supports.

[0052] An optional second frame 8 can be arranged circumferentially around the frame 1, preferably congruent with the frame 1 and below the frame 1, wherein the end frame sections 5, 6 are pivotable relative to the second frame 8 and can be fixed in a pivoted position, e.g. by means of a locking device or support. In general, all slats are arranged parallel to the narrow sides 3 and approximately parallel to the plane spanned by the frame 1. The ends of the slats have, as is generally preferred, the same cross-section and are held in recesses of supports 7 which are fixed opposite one another on the long sides 2. As is generally preferred, two adjacent slats are held by their ends in a common support.

[0053] Twelve slats 10 are arranged on each of the first end frame section 5 and the second end frame section 6. The two slats 10 immediately adjacent to the respective end narrow side form an end region 14 and are preferably non-resilient. Generally, non-resilient slats 10 are preferably straight.

[0054] Immediately adjacent to the central frame section 4, four slats form a lumbar area 15. A shoulder area 16 is formed by six slats which are arranged between the

[0055] end region 14 and the lumbar region 15. The slats which form the shoulder region on the first end frame section 5, also referred to as the first shoulder region 16a, are held by resilient supports 7c, the slats which form the shoulder region 16 on the second end frame section 6, also referred to as the second shoulder region 16b, are held by non-resilient supports 7d. The slats 11 of one shoulder region 16, which is the first shoulder region 16a or the second shoulder region 16b, are slats 11 which are cranked between their ends 9 and their middle section 11a, and the slats 13 of the other shoulder region, which is correspondingly the second shoulder region 16b orthe first shoulder region 16a, have at least in their central section 13a a central elongated hole parallel to the longitudinal extension of the slat, wherein the four slats which form the lumbar regions 15 on both sides of the pelvic region 17 and the central frame section 4 are slats 12 with adjustable spring action and are held on height-adjustable supports 7b, wherein the four slats 12 which form the pelvic region 17, which extends as preferred over the central frame section 4, are slats 12 with adjustable spring action and are held on non-height-adjustable supports 7a.

[0056] As is generally preferred, each slat 10, which is directly adjacent to the respective end narrow sides 3 of the frame 1, has a projection 10a facing the respective end narrow side 3, which projects beyond the cross-section of its ends 9. Each slat 10, optionally two slats 10, which are directly adjacent to the respective end narrow sides 3 of the frame 1, are preferably non-resilient slats 10 and are held by supports that are non-height-adjustable supports 7a and non-resilient supports 7d. Optionally, all slats have the same length. Preferably, the slats 10 arranged in the end regions 14 and the slats 7a arranged in the pelvic region 17, optionally also the slats 7b arranged in the lumbar region 15, have the same length and are in particular longer than the slats 7c, 7d arranged in one of the shoulder regions 16, 16a, 16b.Generally, the slats 7c, 7d arranged in one of the shoulder regions 16, 16a, 16b preferably have the same length so that they are interchangeable. Accordingly, the pocket spring mattress (100) can have slats (10) of the slatted frame arranged in the end regions (14), wherein the slats (7a) arranged in the pelvic region (17) and the slats (7b) arranged in the lumbar region (15) have the same length and are longer than the slats (7c, 7d) arranged in one of the shoulder regions (16, 16a, 16b), which each have the same length, and the distance between the slats of the slatted frame and the long sides (2) can be spanned by supports (7a, 7b, 7c, 7d) and the long sides (2) of the end frame sections (5, 6) and the central frame section (4) are arranged at the same distance from one another.

[0057] The Figure 2shows a second frame 8 which circumferentially surrounds the frame 1, wherein the central frame section 4 is rigidly attached to the second frame 8 or is formed by it, and the first terminal frame section 5 and the second terminal frame section 6 are articulated symmetrically along the extension of the long sides 2 on the second frame 8 at a pivot joint 18 and therefore, for example, also have the same length.
