The lift components may include frontal bars, a tabletop, a central arm, lifting forks, a hoist, a knee blocker, footrests, a transfer chair, detachable handles, and / or safety cushions. Embodiments of the present invention may include one or more patient interfaces. The patient interfaces may attach to the lift cart and / or one or more lifting components. The patient interfaces may include slings, chairs, straps, harnesses, and / or transfer sheets. In one embodiment, the patient interfaces may include foldable panels. In one embodiment, the patient interfaces may include a buttock / link support. Example embodiments of methods of the present invention may include frontal transfers, lateral seated transfers, lateral bed transfers, and sit-to-stand transitions.

A passive gravity balancing assist device for human sit-to-stand motion is provided. The design combines the use of auxiliary parallelograms with springs to produce an orthotic device wherein the total potential energy of the system is constant during standing and sitting motion.

The present invention provides a body lift-assist walker device for gait training is provided by the invention. The patient wears a pressurized body suit over all or a portion of his lower body, and the suit is attached to the walker device. A positive pressure or vacuum condition is applied to the interior of the suit, so that the differential pressure condition across the suit offloads a portion of the patient's body weight to the ground through the supportive walker device to make it easier for him to walk or run. The walker device also includes a lift-assisted body weight support device operated by a constant force mechanism like a pneumatic air cylinder that can lift the patient from a sitting position to a standing position with minimal physical effort. The device provides a portable and convenient system for persons undergoing physical therapy for treatment of gait or balance problems following an injury, stroke, or neurological disorder, or for use by elderly or disabled persons who have encounter difficulties in the sit-to-stand movement or walking.

Mobility device for physically disabled people 1, comprising a chassis 10 with at least one motor for maneuvering the entire mobility device 1; a pivot arm 20, which at its lower end 22 is pivotably connected to the chassis 10; and a pelvis support 40, which is connected to an upper end 23 of the pivot arm 20; wherein a physically disabled person 2 can sit with the pelvis support 40 attached to its body, can move around with the mobility device 1 in a standing position on the chassis 10, and can change on its own from sitting to standing position, wherein all elements of the mobility device 1 except the elements directly contacting the body of the person 2 extending above pelvis height h of the sitting person 2 can be lowered or moved to or below this height h. The present invention further comprises a method for erecting of a sitting physically disabled person 2 and for fixing of the person 2 in standing position onto a motor-driven mobility device 1.

An apparatus for raising and lowering a payload, particularly a chair and its user to provide assistance with the sit-to-stand task. The apparatus comprises a base, a platform, linkages attached between base and platform to allow only vertical motion therebetween, an inflatable bag also situated between base and platform, and a source of pressurized fluid such as compressed air, whereby the bag is inflated and deflated to raise and lower the platform. The user may use an existing, favorite chair, including a reclining chair, which is placed upon the platform without modification. In a low position, the platform is quite close to the floor, providing comfort during sitting. In a high position, the platform is greatly elevated, to provide a full measure of sit-to-stand assistance. The apparatus is compact, doesn't interfere with reclining or rocking while sitting, and is easily deployable, movable, and storable.

The invention discloses a sit-to-stand chair, which comprises a chair bracket, a seat, a rotating frame and a driving mechanism, wherein the rotating frame is used for driving the seat to be inclined relative to the chair bracket so as to assist people on the seat to stand up, and the driving mechanism is used for driving the rotating frame to run. One end of the rotating frame and the top of the chair bracket form a rotating pair, the other opposite end of the rotating frame and one end of the seat also form a rotating pair, and a compound hinge driven by the driving mechanism to rotate is arranged in the middle of the rotating frame. The driving mechanism is used for raising up the rotating pair of the rotating frame and the seat by driving the rotating frame to move around the rotating pair formed by the rotating frame and the chair bracket, and expanding the included angle between the rotating frame and the seat by driving the seat to rotate relative to the rotating frame. During the process of assisting standing up, people can feel that the seat has ascending and rotating trends, the standing-up process is steady, and the final rotating angel of the seat is small, so that the old can be effectively prevented from slipping and falling down. The sit-to-stand chair has a simple structure and is wide in application range.
