Beds and methods for applying a micro traction force on the body of a user over time to treating or relieve back/spinal pain. Embodiments of a bed according to the present invention provide a section of the bed that is movable relative to other sections of the bed and apply a restorative force to the movable section such that when a user lays on the movable section, the movable bed section is displaced and a tractive force is applied to the user’s body due to a force apparatus applying a force thereto. The movable bed section can be suspended by a tensional support and/or supported by a compressional support in various configurations disclosed herein.

Provided is a three-dimensional wave generating device and a multifunctional motion bed having the same. A safety device prevents a driven pulley and/or a driven pulley to which an eccentric shaft is coupled from being separated from a coupling shaft. Therefore, operation stability is secured while noise caused by separation or unstable coupling of the driven pulley and/or eccentric shaft in a three-dimensional wave generating device is prevented from occurring, and when a functional motion bed to which the three-dimensional wave generating device is applied is provided, the user can feel a three-dimensional wave more effectively in bed.

A system can include a zipper that connects a mattress to a bed foundation. For example, the zipper can extend from a head end to a foot end of an adjustable foundation. For another example, a zipper can connect to a mattress along a seam of the mattress and/or to a foundation along a seam of a foundation. For another example, a first zipper can connect the mattress core to a second zipper and the second zipper can connect a foundation to the first zipper. For another example, first and second zippers can be substantially vertically aligned.

A head elevation apparatus configured to be positioned under a mattress may include a base panel and a top panel positioned on the base panel. The top panel may include a center panel hingedly coupled to the base panel. An upper flap may be hingedly coupled to the center panel. A lower flap may be hingedly coupled to the center panel.

A mattress support assembly includes a mattress cover that has a coupling feature. A support casing defines an attachment feature and is selectively coupled to the mattress cover via the coupling feature. A support member is operably coupled to the attachment feature of the support casing. The support member has a load surface, a base surface, and an expandable body defined between the load surface and the base surface.

The present invention discloses a multifunctional motion simulation bed which has multiple segments and simulates preprogrammed motions. The segments are articulately connected to form a motion platform. In one embodiment, the segments are disposed above a base. Actuators are mounted on the base and pivotally coupled with the base and the segments. A microprocessor drives the actuators individually and causes the motion platform to simulate motions. In another embodiment, the segments are disposed above a frame which is arranged above a base. One segment is fixed on the frame. Some actuators are pivotally coupled with the frame and some of the segments. Other actuators are pivotally coupled with the frame and the base. A microprocessor drives the actuators individually and causes the frame and motion platform to simulate motions.

The present invention relates to the field of bed frame structures, and in particular, to a novel detachable bed frame assembly mechanism. The novel detachable bed frame assembly mechanism includes a bed frame body. The bed frame body includes an outer frame, an inner frame, and two sets of wooden strips. The outer frame is a rectangular frame including two horizontal tubes, two lateral tubes, four L-shaped iron-plate connectors, bolts, and nuts. The inner frame includes at least one horizontal connecting tube, a plurality of lateral connecting tubes, iron sheets, bolts, and nuts. The two sets of wooden strips are symmetrically disposed on the horizontal connecting tube and the horizontal tubes on both sides of the horizontal connecting tube and are parallel to the lateral tubes, to connect the horizontal connecting tube to the horizontal tubes. The invention is easy to assemble and disassemble and is safe and reliable.

A pneumatic adjustment module is attachable to a support panel of a bed. The module has a base received on a support panel of the bed and a tilt panel attached to the base with a vertex hinge. A bladder is positioned between the base and tilt panel. The bladder may have a plurality of expansion segments. The bladder is pneumatically expandable from a deflated condition to an inflated condition. The tilt panel is substantially parallel to the base in the deflated condition and in the inflated condition has an effectively triangular expanded cross section with a vertex proximate the vertex hinge providing the tilt panel with a tilt angle with respect to the base.

A modular system is usable to vary the conditions around a bed in a home to provide various levels of support for patients who are at home and have varying acuity of medical complications. The modular system allows the home bed to be temporarily adapted for medical care.

An air mattress includes a first air cell, a second air cell, a plurality of third air cells, and a body-lifting air cell. The second air cell includes a first air chamber, a second air chamber, and a structurally-weakened region. The body-lifting air cell is below the second air cell and at least one of the third air cells. The body-lifting air cell is inflated by an air source controlled by a control system. When the body-lifting air cell is inflated, a vertical distance between the top of second air cell and the bottom of air mattress is greater than a vertical distance between the top of first air cell and the bottom of air mattress. When the body-lifting air cell is inflated, the second air cell has a lower structural strength than the other air cells to have a cushioning effect against external forces.
