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.

A chair includes a seat pan member, a movement support frame, and at least two movement support members operatively connected to the seat pan member and the movement support frame. The at least two movement support members are configured to support the seat pan member in a floating manner for dynamic movement with respect to the movement support frame in at least one degree of freedom in a horizontal seating plane.

The invention 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 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).

An apparatus that supports a user in a variety of positions to comfortably perform tasks, such as applying one or more tattoos to skin of a subject is herein disclosed. The apparatus can be reconfigured to optimally position and support the arms and/or chest of the user. A method for using a stool can involve rotating armrests of the apparatus from a stowed position to a deployed position. The armrests can support the user's forearms while supporting the user's chest such that the user can comfortably perform tasks in front of a chest support of the stool.

There is noticed a dynamic frame of the chair, which comprises a seat holder (1), to which a swivel sleeve (3) is demountably attached from one side, into which a spherical head (41) of a spherical thread swivel (4) with a threaded end piece (42) is tightly seated, to which a nut (7) is demountably attached and to which a silent block bushing (2) is demountably attached from the other side, to which an annular locking ring (6) with four locking undercuts (61) and four locking noses (62) is demountably attached from one side and a frame sleeve (5) with a sliding hole (53) and four sleeve noses (51) and four sleeve reinforcement pieces (52) is detachably fastened from the other side.

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.

“Thron” is Swedish for throne and so is the ideal name for the product being described here in this abstract. A novel and unique ergonomic chair created for the purpose of sitting for extended periods of time. The human body when forced to remain sedimentary begins to accumulate neural toxins. Toxins like uric and lactic acid become difficult to remove from the body because of a lax seated position over a prolonged period of time. The intended use of Thron as an ergonomic chair is to increase blood circulation and enhance postural awareness from sitting on the air-filled rubber inserts.

A chair for fitness exercise includes a base, a stretching mechanism, a backrest, an armrest, a footrest and a supporting cushion. The stretching mechanism includes a pull rod and an elastic connector. One end of the elastic connector is fixedly connected to the base, and the other end of the elastic connector is connected to the pull rod. The base includes a footrest rod, and one end of the elastic connector is fixedly connected to the footrest rod. The backrest includes a backrest rod. The armrest is connected to the base, and an elastic assembly is fixedly arranged on the armrest. The footrest includes two side supporting rods. The supporting cushion is arranged between two side supporting rods. The elastic assembly includes a connecting rod, a first limiting member, a second limiting member, a third limiting member, a front spring, a rear spring, a first sleeve and an engaged key.

This invention concerns hoodie garments, Such garments have a sewn on, tied on, Velcro secured on, or otherwise attached button, knob, or other similar device on the middle part of the head covering portion of the hoodie so as to provide a support point for a facemask across a user's mouth and nose.

A portable therapeutic unit and system for treating a back, a neck, or the back and the neck of a user is disclosed. The therapeutic unit includes a first seat, a back support, a hinge, and a metal back. The first seat is designed for the user to sit thereupon. The back support is designed to support a back of the user. The hinge pivotally connects the first seat and the back support. The metal back is connected to the back support, with the metal back magnetically coupling with an attachment magnet. Further, the attachment magnet couples to a therapeutic aid to deliver treatment to the user.
