The foot frame, the shank link, the connecting link, and the knee link constitute a four-bar linkage.

Apparatus for supporting a person in a prone position comprises a support stand and a platform movably mounted to the support stand by a linkage, in which the platform is movable on the linkage between a first position and a second position, in which the platform comprises an upper portion in a first plane and a lower portion comprising a concavity relative to the first plane.

Sitting furniture (100) comprising a seat (110), a lower leg support (120) and a chest support (130). The invention is characterised in that the seat (110) is arranged to support the posterior thigh (11) and/or buttocks (12) of a seated user (10) such that the femur bone (13) of the seated user (10) is downwards inclined in the anterior direction at an angle of at least 40° downwards in relation to the horizontal, in that the lower leg support (120) is arranged to support the anterior side of the lower legs (14) of the seated user (10), and in that the chest support (130) is arranged to support the chest (15) of the seated user (10) in a forward leaning position of the seated user (10) such that the third lumbar vertebrae body (16) of the seated user (10) is arranged in a support plane (150), which support plane (150) is perpendicular to the sagittal plane of the user and in which support plane (150) the respective pivot point (17) of the seated user's (10) hip joints and the respective pivot point (18) of the seated user's (10) shoulder joints are also arranged when the posture of the seated user (10) is symmetric about the seated user's (10) sagittal plane.

An inversion chair and the method of treatment are provided to assist a user in the treatment and prevention of migraine headaches by increasing and altering the blood flow within the head. The inversion chair includes a frame having a first and a second side connected to each other by a fixed backrest. The sides of the frame have L-shaped configurations comprising upstanding side and base sections that are connected by a curved member. A rotatable seat is positioned between the sides of the frame. The chair is adapted to transition between a standard sitting position to an inverted position. The chair comprises an upper user support bar and a lower leg support bar for maintaining a user within the chair during inverted use. The support bar is removable and used to either secure the lap of the individual when inverted, or support the chair when in an upright state.

Novel sit-stand seating devices, more particularly, to sit-stand seats or stools that can tilt forward to provide balanced support for seated to near-standing postures and methods of their use are disclosed. The sit-stand devices are useful, inter alia, to provide stabilized worker positioning to carry out a task for a range of sitting through standing postures in an environment associated with a task for a worker in need thereof.

An accessory support attachment for coolers that is selectively couplable thereto and operably configured to support accessories thereon, the attachment comprising a support sidewall of a substantially rigid material with a first portion hingedly and lockably couplable to a second portion, at least one accessory support member selectively and slidably coupled to an outer surface of the support sidewall, a first and second plurality of enclosures coupled to the accessory support member and operably configured to retain accessories therein, a handle member designed to facilitate greater ease of transport of coolers, and a back support frame member operably configured to function as a backrest and support the weight of a user when seated on the cooler and leaning back, on, or against the back support frame member.

An ergonomic method for working in confined work spaces is disclosed. The method, in some cases, includes the steps of: a) providing a support structure that is generally in the configuration of a rectangular prism having six faces, a length, width, and a height in which the length, width, and height differ from one another so that the structure provides three different height positions when the support structure is placed on the floor of the workspace; b) placing the support structure with one of its faces in contact with a contoured floor surface in a confined work space; and c) sitting or standing on the support structure.

A flight attendant seat comprises a carrier having a guide with opposed first and second ends, and a storage compartment receiving the guide first end. The guide provides guidance along its length between its first and second ends. The seat comprises a plurality of segments, each slidingly mounted to the guide to allow a sliding movement of the segments along the guide and relative to the carrier device between a stored position of the segments within the storage compartment, and an exposed position of the segments. A seat element is pivotally mounted to a first of the segments pivotable between an inoperative and operative seat forming position. At least one backrest is mounted to at least a second of the segments. With the segments in their exposed position, the seat element, when pivoted to its operative position, together with the backrest(s), can be used as a flight attendant seat.

Systems and methods for exerting forces on a body, including a support structure defining a space and a plurality of surface contacting units that are configured to exert force upon the body, such that the weight is distributed away from the primary weight bearing regions to non-weight bearing regions of the body, or vice versa, without exerting significant shear or frictional forces on surfaces of the body. The systems and methods may be used to exert forces to cause fluid shift in different compartments of the body. Applications include treatment of various disease conditions including pressure ulcers, heart failure, high blood pressure, preeclampsia, osteoporosis, injuries of spine and to slow microgravity-induced bone and muscle loss. The systems and methods may be used to simulate gravity, weightlessness or buoyancy, in rehabilitation medicine. The system may include a chair, bed, a wearable suit or an exoskeleton.
