An apparatus (1) for positioning the body of a user (100), wherein the apparatus can be used in a seat or in the form of a rest, comprising a seating element (20), a pelvis and lumbar-spine module (13) and a computer unit (40), wherein the pelvis and lumbar-spine module comprises an adjusting element (117) and a sensor (113), and the seating element comprises an adjusting element (108) and three sensors (111, 112), wherein the sensors (111, 112, 113) sense seat-related and rest-related pressures, wherein the computer unit activates the adjusting elements, wherein a first and second sensor (112) and a third sensor (111) sense the seat-related pressure of the first and second ischial tuberosities (102) and of the coccyx (104), wherein the first and the second ischial tuberosities define an ischial-tuberosity level, wherein the adjusting element of the seating element compensates for the ischial-tuberosity level horizontally about the user's sagittal axis, and whereupon the adjusting element of the pelvis and lumbar-spine module tilts the user's pelvis (101) about the horizontal axis of the same until the seat-related and/or rest-related pressure of the coccyx has a value substantially equal to zero.

A physical conditioning and therapeutic conditioning system that, when configured and incorporated into the construction of a chair, has a seat, a base configured to rest on a surface, and a seat-support mechanism which is configured to couple the seat to the base and enables the seat, when unlocked in one embodiment, to be pivoted in any direction while rocking in the seat and using one's own body weight for resistance. Ideally the seat-support mechanism permits universal motion in all directions above a vertical axis, including front to back inflection and side-to-side inflection of at least 40° , including 360° of rotation on a universal type joint. The universal type joint is a ball joint consisting of a bearing stud and socket enclosed in a case, with all parts made of steel. In one embodiment, the bearing stud is tapered and fits into a hydraulic post. A ball joint is used to allow free rotation in two planes at the same time.

The universal ball joint when attached to the underside of a seat is surrounded by a metal caste collar, also attached to the underside of the seat, and with a locking system attached to the upper collar. Inserted into the upper collar, along with a lower collar attached to the arm support structure, surrounding the ball joint assembly is a hardened metal coiled spring, used ideally to stabilize, through compression, the seat in a horizontal position and allow for locking the seat in a horizontal position, when no force is applied or when not in use.

This disclosure relates to a seat device (1) comprising an underframe (2) and a seat (3) connected to the underframe (2) in such a way as to pivot about a pivot seat axis (A1), there being provided means for elastically biasing the seat (3) in anti-clockwise rotation. The seat device (1) further comprises a lumbar part (42); rotationally secured to the seat (3), and a saddle (5) for supporting the top of the thighs of the user, the saddle (5) being connected to the front region of the seat (3).

A control mechanism (20) for a chair (100) comprises a baseplate (21) configured to be coupled to a chair base assembly (102), a support plate (22) configured to be coupled to a chair seat (103), and an elastic element (23) arranged between the base plate (21) and the support plate (22). The elastic element (23) enables the support plate (22) to be tilted with respect to the base plate (21) around a first tilt axis and a second tilt axis different from the first tilt axis. The control mechanism (20) further comprises a control handle (24) configured to be actuated in an actuating direction (34), and at least one stop element (26A-26D). Each stop element is arranged between the base plate (21) and the support plate (22) and configured to limit a minimum distance between the base plate (21) and the support plate (22) at the position of the corresponding stop element (26A-26D). A stop element adjust mechanism (28) is coupled to the control handle (24) and configured to adjust the minimum distance of each stop element in response to actuating the control handle in the actuating direction (34).

A multifunctional chair is disclosed, including: a first frame body unit, the first frame body unit including a head end and a tail end; a first supporting unit configured to support the first frame body unit, the first supporting unit connected with a first connecting position of the first frame body unit and a height of the tail end of the first frame body unit being lower than a height of the first connecting position; a first leaning unit arranged in a position of the first frame body unit close to the first connecting position; a second frame body unit arranged on a back portion of the first frame body unit, the second frame body unit and the first frame body unit being rotatably connected, the second frame body unit and the first frame body unit in rotatable connection being capable of moving between a first posture of a reclining chair or a seat and a second posture of fitness equipment, the second frame body unit and the first frame body unit being in the first posture when having an angle, and the second frame body unit and the first frame body unit being in the second posture when the tail ends of the second frame body unit and the first frame body unit are overlapped; and a second leaning unit arranged on the second frame body unit. The multifunctional chair has multiple functions and is also used for seats, recliners and fitness equipment, and has simple structure, simple and fast operation, convenient use, and easy to carry and transport.

A support for a piece of seating furniture provides an additional degree of freedom of movement. The support has a connecting unit fitted on a main body that connects to a supporting element of an underframe. The connecting unit has a mounting device for the supporting element, in particular a mount for the upper end of the supporting element. The connecting unit is fitted on the main body such that it is possible to alter the inclination of the main body relative to the supporting element. For that purpose the main body has a preferably convex contact base, which in the fitted state is contacted by a contact head of the connecting unit, with the abutment forming a non-planar contact rather than a contact over a surface area, in particular a punctiform contact.

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.

The presently claimed subject matter is directed to furniture elements. Further, the presently claimed subject matter concerns a furniture covering element configured with a cushioning arrangement.

Joint arrangement (10) has a hollow cylindrical receiving cylinder (20) that extends in a cylinder axis direction (Z) and receives one end of a chair column (30) of an active-dynamic wobble chair, the latter movably mounted in a substantially hollow cylindrical outer joint shell (40) composed of joint shell segments (45). Movable mounting of receiving cylinder (20) is achieved by deformable elastic elements (50) arranged to be variable in shape and position in a bearing gap (60) between an outer wall portion (21, 22) of the receiving cylinder (20) and an inner wall portion (41, 42) of the joint shell (40). Receiving cylinder (20) is actuated in a force-dependent manner, whereby shape and/or position of the elastic elements (50) change as viewed in a radial direction (Rs) from changing, preferably reducing, clearance of the bearing gap (60) when the receiving cylinder (20) is actuated in a cylinder axis direction (Z).
