     DETAILED DESCRIPTION 
     The disclosure generally relates to an adjustable bed apparatus, in particular an adjustable bed foundation. The adjustable foundation includes independently adjustable lumbar and neck support structures on an adjustable back/head section of the adjustable bed foundation. In some embodiments, the lumbar and neck support structures include inflatable air bladder structures. In other embodiments, the lumbar and neck support structures include mechanically actuatable subsections of the adjustable back/head section of the adjustable bed foundation. 
       FIG. 1  is a side view of an adjustable bed  10  according to the disclosure. The illustrated adjustable bed  10  includes an adjustable foundation  20  (e.g., adjustable bed foundation), a mattress  300  sitting atop the adjustable foundation  20 , and a lumbar and neck support system  400  (e.g., lumbar support structure  410  and neck support structure  420  positioned at one or more locations on a back/head portion of the foundation  20  and in direct or indirect contact with the mattress  300 ). In other embodiments, the adjustable bed  10  can include a rail system  500  as illustrated in  FIG. 12  and  FIG. 13 . In some embodiments the adjustable bed  10  can include both the lumbar and neck support system  400  and the rail system  500 , and in some embodiments the bed  10  can include only one of the two systems  400 ,  500 . The adjustable foundation  20  can include a mattress support (or deck)  100  mounted to an adjustable frame  200 .  FIG. 2  is a top perspective illustration of a mattress  300  according to the disclosure. 
     The mattress support  100  includes a deck support  110  platform, for example including a plurality of deck support sections  110 A- 110 D as illustrated. A deck support platform  110  formed from a plurality of deck support sections  110 A- 110 D, each having a corresponding upper surface  112 A- 112 D (i.e., the surface which supports the mattress  300 ) is suitable for the adjustable foundation  20 . In the illustrated embodiment, section  110 A corresponds to the foot portion of the bed, section  110 B corresponds to the leg portion of the bed, section  110 C corresponds to the bottom portion of the bed, and section  110 D corresponds to the head and neck portion of the bed  10  (i.e., where the sections correspond to the body portion of a user laying on the bed  10 /mattress  300  in a normal use orientation). Each section  110 A- 110 D includes longitudinally opposed ends  110 A 1  and  110 A 2 ,  110 B 1  and  110 B 2 ,  1100   1  and  1100   2 ,  110 D 1  and  110 D 2 , respectively, where the longitudinal direction Y is generally defined as being perpendicular to the pivot axis P (described below) and/or along the mattress support  100  length or mattress  300  length. Each deck support section  110 A- 110 D can be pivotally attached to one or more adjacent sections (e.g., directly or indirectly via underlying frame  200  structure as described below), thus allowing each section  110 A- 110 D to rotate independently around the lateral pivot axis P (e.g., an axis generally in the lateral direction X and perpendicular to the longitudinal direction Y). The mattress support  100  generally includes at least two deck support sections, for example including a fourth (foot) support section  110 A, a third (leg) support section  110 B pivotally attached to the fourth section  110 A, a second (bottom) support section  110 C pivotally attached to the third section  110 B, and a first (back/neck/head) support section  110 D pivotally attached to the second section  110 C as shown in  FIG. 1 . In other embodiments (not shown), the mattress support  100  can have fewer or more support sections (e.g., a third (foot) support section, a second (leg and bottom) support section pivotally attached thereto, and a first (back/head/neck) support section pivotally attached thereto). In some embodiments the support sections  110 A- 110 D can be formed from a rigid support material such as wood or metal. In other embodiments the support sections  110 A- 110 D can be formed from a flexible fabric or padding material (e.g., alone or in combination with a rigid support material, such as a cover or padding for an underlying rigid support material). 
     The adjustable frame  200  generally provides the mechanical, electrical, and electronic support and articulation components for the adjustable foundation  20  and bed  10 . As illustrated, the adjustable frame  200  includes a frame support  210 , for example including a plurality of frame support sections  210 A- 210 D as illustrated and corresponding to the deck support sections  110 A- 110 D. Each deck support section  110 A- 110 D can be fixedly or removably mounted (e.g., via bolts, screws, or other fastener or adhesive components) to its underlying frame support section  210 A- 210 D such that when one or more frame support sections  210 A- 210 D are articulated, the deck support sections  110 A- 110 D are correspondingly articulated. As illustrated, each frame support section  210 A- 210 D can be pivotally attached at a pivot axis P to one or more adjacent sections (e.g., directly as illustrated and providing an indirect pivotal attachment for corresponding deck support sections), thus allowing each section  210 A- 210 D to rotate independently around the lateral pivot axis P. The adjustable frame  200  generally includes at least two frame support sections, for example including a first (foot) support section  210 A, a second (leg) support section  210 B pivotally attached to the first section  210 A, a third (bottom) support section  210 C pivotally attached to the second section  210 B, and a fourth (head/neck) support section  210 D pivotally attached to the third section  210 C as shown in  FIG. 1 . In other embodiments (not shown), the adjustable frame  200  can have fewer or more frame support sections (e.g., a first (foot) support section, a second (leg and bottom) support section pivotally attached thereto, and a third (head/neck) support section pivotally attached thereto). 
     As illustrated, the adjustable frame  200  further includes a subframe  230 , for example a rigid, non-articulatable frame structure which sits on a floor or within a decorative bed frame common in the furniture industry such as a platform bed (e.g., via various leg elements, not shown) and provides stability for the bed foundation  20  as the adjustable frame  200  is articulated to various different positions. The subframe  230  can include one or more structural components, for example including longitudinal subframe members  232 , lateral subframe members  234 , and/or feet or legs  236  ( FIGS. 3, 4, 12, and 13 ). The adjustable frame  200  can further include one or more support members  220  connecting structure between the subframe  230  and the frame support  210  and sections  210 A- 210 D thereof. The support members  220  can include one or more vertical support members  226  as well as one or more longitudinal support members  222  and/or lateral support members  224  mounted to the vertical support members  226  to provide a base or support for the frame support  210  ( FIGS. 3, 4, 12, and 16-18 ). The vertical support members  226  can be mounted to the subframe  230  or components thereof, and the longitudinal and/or lateral support members  222 ,  224  can be mounted to the vertical support members  226 . In some embodiments, the adjustable frame  200  can further include rollers  228 , for example mounted to the vertical support members  226 , which rollers  228  engage the longitudinal subframe members  232  and permit longitudinal movement forward or backward of the support frame  220 , frame support  210 , and the mattress support  100  ( FIGS. 3, 4, 12, and 14 ). In some embodiments the vertical support members  226  are fixedly mounted to the subframe  230  or component thereof ( FIG. 16 ). In such embodiments, the support frame  220  is in a stationary or fixed longitudinal and lateral position relative to the subframe  230 , although rotational movement or articulation of the frame support  210  and the mattress support  100  is possible. In some embodiments, one or more of the frame sections  210 A- 210 D can be fixed in position relative to the subframe  230  (e.g., bottom section  210 C as illustrated) and be unable to rotate or articulate relative to the subframe  230 , although other frame sections pivotally attached thereto are able to rotate or articulate. As further illustrated, the adjustable frame  200  can include one or more actuators  240  variously mounted to one or more of the subframe  230 , a support member  220 , and a frame support section  210 A- 210 D. In some embodiments, the subframe  230 , the support members  220 , and the frame support sections  210 A- 210 D can be formed from metal such as steel. The actuators  240  can be any of those commonly known in the art. The actuators  240  and, correspondingly, the configuration or position of the adjustable frame  200 , mattress support  100 , and mattress  300  can be controlled and adjusted by a suitable power supply (not shown), adjustable bed controller  250  (e.g., programmable logic controller or otherwise), and remote control to deliver repositioning commands (not shown). 
     The mattress  300  is not particularly limited, and it can be a conventional mattress  300  (e.g., a spring or coil mattress, memory foam mattress, air mattress) with a base  310  (e.g., a continuous fabric material) suitable for use on a mattress support structure such as a fixed bed frame or an adjustable bed frame. The mattress suitably has a thickness of at least 20 cm (e.g., at least 20 cm, 30 cm, or 35 cm and/or up to 30 cm, 40 cm, or 50 cm). In the illustrated embodiment, the mattress  300  includes a mattress containment frame  305  including a plurality of foam cells (or foam springs)  340  positioned in the frame  305  to provide the sleeping support surface for the mattress. The mattress containment frame  305  includes a lower/bottom base  310 , sidewalls  320 , and endwalls  330  which generally define the interior frame  305  volume housing the foam cells  340 . The sidewalls  320  and endwalls  330  suitably are formed from a foam material. The base  310  can be a generally continuous fabric material. The mattress  300  is generally positioned above the mattress support  100  surface  112 , for example sitting directly atop the deck support sections  110 A- 110 D. In other embodiments, other structure between the mattress  300  and mattress support  100  surface  112  can be present, for example a padding or cushion material. 
       FIGS. 3-6  illustrate an embodiment in which the lumbar and neck support system  400  includes an inflatable lumbar support  410  and an inflatable neck support  420 . Suitably, the inflatable supports  410 ,  420  are formed from a durable fabric or plastic material. The inflatable lumbar support  410  is positioned in a bottom region B of the first deck support section  110 D (e.g., bottom 20%, 30%, 40%, or 50% of longitudinal length L of the first deck support section  110 D, measured relative to the end of the first deck support section  110 D adjacent the second deck support section  110 C), such that the lumbar support  410  exerts pressure when inflated against the lumbar region of a person laying or sitting on the adjustable bed  10 . Similarly, the inflatable neck support  420  is positioned in a top region T of the first deck support section  110 D (e.g., top 20%, 30%, 40%, or 50% of longitudinal length L of first deck support section  110 D, measured relative to the end of the first deck support section  110 D corresponding to the head end of the adjustable bed  10 ), such that the neck support  420  exerts pressure when inflated against the neck region of a person laying or sitting on the adjustable bed  10 . The inflatable lumbar support  410  laterally extends across the first deck support section  110 D and is disposed on an upper surface  112 D of the first deck support section  110 D. Suitably, the inflatable lumbar support  410  and/or the inflatable neck support  420  extends at least 60%, 70%, 80%, or 90% of the mattress support surface  100  lateral width W. In some embodiments, the inflatable lumbar support  410  and/or the inflatable neck support  420  is a single inflatable bladder extending across the first deck support section  110 D (e.g., at least 60%, 70%, 80%, or 90% of the lateral width W of the mattress support surface  200  or the first deck support section  110 D, such as for a twin, queen, or king size bed). In other embodiments, the inflatable lumbar support  410  and/or the inflatable neck support  420  includes a plurality of inflatable bladders  410 A,  410 B and/or  420 A,  420 B extending across the first deck support section  110 D. For example, there can be two separate bladders on adjacent support halves corresponding to a bed section for a first person and a second person such as on a queen, split queen, king, or split king bed  10 . The plurality of bladders can be in fluid communication so that they inflate/deflate together, or they can be fluidly isolated from each other so that they can be independently inflated and deflated. As specifically shown in  FIG. 4 , the bed  10  can further include a means  430  for supplying pressure to the inflatable lumbar support  410  and the inflatable neck support  420 , for example including an air pump or compressor along with suitable valves and tubing (not shown) for independently inflating and deflating the various supports/bladders. 
     In a particular embodiments shown in  FIGS. 5 and 6 , the bed  10  can further include a flexible lumbar pressure distribution member  414  mounted to the first deck support  110 D section and at least partially covering or enclosing the inflatable lumbar support  410 . Similarly, the bed can include an analogous flexible neck pressure distribution member (not shown) mounted to the first deck support section  110 D and at least partially covering or enclosing the inflatable neck support  420 . For example, the pressure distribution member can be a thin but rigid plastic material or sheet that can deform and conform to the curvature of the underlying bladder, but which provides lateral support to laterally distribute the pressure of a person&#39;s lumbar/back or head/neck to lessen bladder sag in the region where the person is located. One longitudinal end of the pressure distribution member can be fixedly mounted to the first deck support section  110 D and the opposing longitudinal end can have a floating or sliding mount such as through a sleeve  416  fixedly mounted to the first deck support section  110 D (e.g., where the illustrated sleeve  416  can further accommodate a complementary neck pressure distribution member when present). 
       FIGS. 7-11  illustrate an embodiment in which the lumbar and neck support system  400  is in the form of a multi-section first deck support section  110 D. The first deck support section  110 D includes a longitudinally extending support frame  114 D (e.g., steel or other metal) pivotally attached to the second deck support section  110 C, a lumbar support deck section  440 , a back support deck section  450 , and a head support deck section  460 . The a back support deck section  450  is fixedly mounted to an upper surface of a middle section of the support frame  114 D. The a lumbar support deck section  440  is pivotally mounted to the second deck support section  110 C and is positioned above an upper surface of a bottom section of the support frame  114 D (e.g., having an opposing free end adjacent the back support deck section  450 ). The head support deck section  460  is pivotally mounted to the support frame  114 D and is positioned above an upper surface of a top section of the support frame  114 D (e.g., having an opposing free end at the head end of the bed  10 ). 
     The lumbar and neck support system  400  further includes first, second, and third actuators  462 ,  464 , and  466 . The first actuator  462  has a first end  462 A mounted to one or more of the second deck support section  110 C (e.g., a supporting frame member thereof) and the stationary bed frame  200 , and a second end  462 B mounted to the support frame  114 D. The first actuator  462  is adapted to move the support frame  114 D between articulated and substantially flat positions relative to the stationary bed frame  200 . Suitably, the first end  462 A has a fixed pivotal attachment to the second deck support section  110 C and/or the stationary bed frame  200 , and the second end  462 B has a fixed pivotal attachment to the support frame  114 D. The second actuator  464  has a first end  464 A mounted to the support frame  114 D, and a second end  464 B mounted to the lumbar support deck section  440 . The second actuator  464  is adapted to move the lumbar support deck section  440  between articulated and substantially flat positions relative to the support frame  114 D. Suitably, the first end  464 A has a fixed pivotal attachment to the support frame  114 D, and the second end  464 B has a floating pivotal attachment to the lumbar support deck section  440  (e.g., floating wheels or rollers contacting the lumbar support deck section  440 ). The third actuator  466  has a first end  466 A mounted to the support frame  114 D, and a second end  466 B mounted to the neck support deck section  460 . The third actuator  466  is adapted to move the neck support deck section  466  between articulated and substantially flat positions relative to the support frame  114 D. Suitably, the first end  466 A has a fixed pivotal attachment to the support frame  114 D, and the second end  466 B has a floating pivotal attachment to the neck support deck section  460  (e.g., floating wheels or rollers contacting the neck support deck section  460 ). 
       FIGS. 12-18  illustrate an adjustable bed  10  according to another aspect of the disclosure in which the bed  10  includes a rail system  500 . Although the embodiments in  FIGS. 12-18  are generally illustrated as including the lumbar support  440  of the lumbar and neck support system  400  as described above, it is understood that embodiments of the adjustable bed  10  including rail system  500  can include some, all, or none of the various features of the lumbar and neck support system  400 . 
     The adjustable bed  10  includes a stationary bed frame  200  that includes a stationary subframe  230  and that can further include one or more support members  220  mounted to the subframe  230  for supporting a mattress support surface  100 , one or more deck support sections  110 , and/or one or more frame support sections  210 . The bed frame is stationary in the sense that the subframe  230  and/or components thereof are stationary (e.g., in a fixed position relative to the ground or other underlying support surface for the bed  10 ), although the support members  220 , the frame support sections  210 , the deck support sections  110 , and/or the mattress support surface  100  can be moveable components of the bed  10  relative to the subframe  230  (e.g., longitudinal motion of the support members  220 , rotational motion or articulation of the frame support sections  210 , the deck support sections  110 , and/or the mattress support surface  100 ). The mattress support surface  100  is supported by the stationary bed frame  200 , for example being mounted directly or indirectly to the subframe  230  and/or the one or more support members  220  (when present). The mattress support surface  100  generally includes a first deck support section  110 , and a second deck support section  110  pivotally attached to the first deck support section  110 . In the illustrated embodiments, the mattress support surface  100  includes four pivotally connected deck support sections  110 A,  110 B,  110 C,  110 D corresponding to the foot, leg, bottom, and back/head portions of the deck support  110 , respectively. Similarly, the bed can include an adjustable frame support  210  as a mounting structure between the mattress support surface  100  and the bed frame  200  (e.g., to the support members  220  and/or the subframe  230 ), for example including frame support sections  210 A- 210 D corresponding to the deck support sections  110 A- 110 D. 
     The rail system  500  generally includes one or more mounting elements  520  fixedly or detachably mounted to the bed frame  200  and one or more rails  510  fixedly or detachably mounted to the mounting elements  520 . As more particularly shown in  FIGS. 14-18 , a given mounting element  520  generally includes a first end  522  mounted (e.g., fixedly or detachably) to the subframe  230  or the support member  220  (when present) and a second end  524 . The second end  524  extends outwardly from the stationary bed frame  200  and is positioned at a location at or below the subframe  230  (e.g., below a plane defined by the subframe  230  or elements thereof) relative to the mattress support surface  100  (e.g., where the location of the mattress support surface  100  defines the relative location above the subframe  230 ). Further, a given rail  510  is (fixedly or detachably) mounted to the second end  524  of a corresponding mounting element  520 . In an embodiment, the first end  522  of the mounting element  520  is detachably mounted to the subframe  230  or the support member  220  (when present). Alternatively or additionally, the second end  524  of the mounting element  520  can be detachably mounted to the rail  510 . The rail  510  generally extends along an external side of the subframe  230  (e.g., along the entire side length thereof), for example along an external side generally parallel with a longitudinal subframe element  232  corresponding to a left or right side of the adjustable bed  10 /bed frame  200 , or along an external side generally parallel with a lateral subframe element  234  corresponding to a head or foot end of the adjustable bed  10 /bed frame  200 . 
     Various embodiments for the rails  510  are possible. As generally shown in  FIGS. 12-17 , a particular rail  510  can vertically extend below the subframe  230  (e.g., below a plane defined by the subframe  230  or elements thereof, such as toward the floor). Similarly, a particular rail  510  alternatively or additionally can vertically extend above the subframe  230  (e.g., above a plane defined by the subframe  230  or elements thereof, such as toward the mattress support surface). The rail  510  can be configured (e.g., sized/shaped) such that vertical extension of the rail  510  above and/or below the subframe  230  conceals from external view (i.e., relative to the bed  10 ) one or more metal or other structural components below the mattress support surface  100 , such as one or more of the subframe  230 , support members  220 , frame supports  210 , deck supports  110 , actuators  240 , and/or control boxes (not shown). The rail  510  can be made from or otherwise include any desired material, suitable examples of which include one or more of wood and metal (e.g., steel). The rail system  500  can include a plurality of rails  510  which collectively form a rail border  512  around the perimeter around the adjustable bed  10 /bed frame  200 . For example, as illustrated, the rail border  512  can include rails or boards  510 A,  510 B,  510 C,  510 D corresponding to the foot, (right) side, (left) side, and head portions of the rail border  512 , respectively. In a particular embodiment, the rail system  500  includes at least 4 rails  510  (e.g., rails  510 A- 510 D) and at least 4 corresponding mounting elements  520 , such that there is at least one corresponding mounting element  520  for each rail  510  and the rails  510  collectively form the continuous rail border  512  around the external perimeter of the adjustable bed  10  (e.g., foot, head, and side rails  510 , and one or more corresponding mounting elements  520  for each rail  510 ). 
     In some embodiments, and as shown in  FIGS. 12, 12A, 12B, and 13 , the mattress support surface  100  further includes at least a first deck support spacer  116 , which extends along an external side  118  of the first deck support section  110  and vertically extends below the first deck support section  110  (e.g., toward the subframe  230 ), and a second deck support spacer  116 , which extends along an external side or edge  118  of the second deck support section  110  and vertically extends below the second deck support section  110  (e.g., toward the subframe  230 ). For example, as particularly illustrated, the mattress support surface  100  can include deck support spacers  116 A,  116 B,  116 C,  116 D along external sides  118 A,  118 B,  118 C,  118 D corresponding to the foot, leg, bottom, and back/head deck support sections  110 A,  110 B,  110 C,  110 D, respectively. The foot and head deck support sections  110 A,  110 D can further include deck support spacers  116  along their external end or edge  118 . In an embodiment, when the mattress support surface  110  is in a flat configuration, the deck support spacers  116  and the rail  510  can form a substantially continuous side surface  530  to the adjustable bed  10  (e.g., to the stationary bed frame  200 ), such as along a lateral or longitudinal edge of the bed  10 /bed frame  200 . In a refinement, the deck support spacers  116  and the rail  510  can have complementary shapes such that they are in contact to form the continuous side surface  530 . In another refinement, the deck support spacers  116  and the rail  510  can have complementary shapes such that they are in close proximity to form the continuous side surface  530  having a small gap  532  (e.g., at least 1 mm, 2 mm, 5 mm, 10 mm, or 25 mm and/or up to 5 mm, 10 mm, 15 mm, 25 mm, or 50 mm) between adjacent elements (e.g., two adjacent spacers  116 , an adjacent spacer  116  and rail  510 ). In another embodiment, the deck support spacers  116  along all head, foot, and side edges of all deck support sections  110  in the adjustable bed  10  collectively form with the rails  510  (e.g., rails  510 A- 510 D) four substantially continuous side surfaces  530  around the entire perimeter of the bed  10 /bed frame  200 . In an embodiment, the deck support spacers  116  are formed from or otherwise include as a component a polymeric foam (e.g., partially or entirely formed therefrom; such as a natural or artificial latex foam, polyurethane foam, etc.). The deck support spacers  116  and the rails  510  can be formed from the same or different materials. For example, all can be formed from wood, all from metal, all from a polymeric foam, etc. Alternatively, all from one group of either the support spacers  116  or rails  510  can be formed from wood, metal, or a polymeric foam, and all from the other group can be formed from a different material such as wood, metal, or a polymeric foam. 
     Various embodiments for the mounting elements are possible, in particular as illustrated in  FIGS. 14-18 . In some embodiments, the mounting element  520  can be mounted to the subframe  230 . For example, the mounting element  520  can be mounted to a longitudinal subframe member  232  extending between head and foot ends of the adjustable bed  10  (e.g., stationary bed frame  200  thereof), such as shown in  FIGS. 12 and 14-16  (connecting the head rail  510 A to the longitudinal subframe member  232 ) and  FIG. 17  (connecting the side rail  510 C to the longitudinal subframe member  232 ). For example, the second end  524  of the mounting element  520  can extend outwardly from the stationary bed frame  200  substantially parallel to the subframe  230  (e.g., substantially in the plane defined by the subframe  230  or components thereof). In a particular embodiment, and as described above, the mattress support surface  100  can be longitudinally slidably mounted to the longitudinal subframe member  232  (e.g., to two longitudinal subframe member  232  on opposing sides of the adjustable bed  10 /stationary bed frame  200 , thus permitting forward/backward movement of the mattress support surface  100  relative to the subframe  230 , such as to move toward or away from an adjacent wall surface during articulation). The slidable mounting can include rollers  228  mounted to the mattress support surface  100 , deck support  110  thereof, or support member  220  mounted thereto, which rollers  228  can roll on the longitudinal subframe members  232 . In some embodiments, the stationary bed frame  200  includes the support member  200 , and the mounting element  520  is mounted thereto. For example, the subframe  230  can omit the longitudinal subframe members  232  extending between head and foot ends of the adjustable bed  10 /bed frame  200 , and the subframe  230  can include a lateral subframe member  234  to provide subframe  230  support, such as shown in  FIGS. 13 and 16 . In a refinement, the support member  220  can be in a fixed position relative to the subframe  220 . In another refinement, the first end  522  of the mounting element  520  can extend downwardly from the support member  220  and the second end  524  of the mounting element  520  extends outwardly from the stationary bed frame  200  substantially parallel to the subframe  230  (e.g., substantially in or below the plane defined by the subframe  230 ), for example as illustrated by the generally L-shaped mounting element or elbow  520  in  FIGS. 13 and 18 . In various embodiments, the mounting element  520  can include a receiving sleeve  528 , for example a U-, C-, or O-shaped sleeve  528  which is shaped or adapted to receive and mount a separate component of the mounting element  520  or a component of the subframe  230  or support member  220  to which the mounting element  520  is attached. As further illustrated, the mounting element  520  can include a slot  526  (e.g., along the length of a sidewall such as in the receiving sleeve  528 ) which permits variable-length attachment (e.g., in the lateral or longitudinal direction) between subframe  230  and the rail  510  (e.g., to facilitate detachable mounting therebetween and/or to accommodate variably sized rails  510  forming a rail border  512  with larger or smaller dimensions).
