A human lift apparatus is disclosed. In various embodiments, the lift apparatus includes a substantially vertical guide rail; a carriage positioned to be moved up and down along the guide rail; a drive mechanism coupled to the carriage and configured to move the carriage at a controlled rate along the guide rail; and a tiltable seat coupled mechanically to the carriage in a manner that allows the seat to tilt about a substantially transverse tilt axis that is substantially parallel to the floor and runs substantially across the seat at a depth that enables a human subject to be seated on the tiltable seat with the center of gravity of the human subject being between the tilt axis and a back end of the seat. The tiltable seat is tiltably mounted in a manner and location that allows the tiltable seat to tilt down, with a front edge of the seat lower than the back edge of the seat, as the center of gravity of the human subject is shifted to a position forward of the tilt axis.

The present invention provides an assembly having a wheelchair and a lift assembly to urge the seat surface upward with respect to the frame from a lowered position when supporting the seated individual during use to an elevated position with respect to the frame assisting the individual during ingress or egress to or from the wheelchair. The lift assembly may include a mechanical linkage and an actuator. The assembly also provides at least one brake configured to block rotation of the wheelchair wheel with respect to the wheelchair frame in a locked state and disengaging with the wheels to allow rotation of the wheel with respect to the frame in an unlocked state. The assembly also provides a brake linkage communicating between the lift assembly and the brake to move the brake into the lock state when the seat surface moved to the elevated position.

According to an aspect of some embodiments of the present disclosure there is provided a chair including a base component, a seat component connected to the base component by a central hinge, and a back-rest component connected to the seat component by a back hinge, wherein when the chair is in a sitting position, the seat component is lower than the central hinge. Related apparatus and methods are also described.

A lift-assist device is disclosed including a seat frame. A seat base can be pivotally coupled to the front side of the frame and moveable between a depressed and extended position. The seat base and seat frame are positionable over the toilet such that a central aperture on the seat base is positioned over the toilet bowl of the toilet. A first arm support can be coupled to the first lateral side of the seat frame and a extends from the top side of the seat frame. A first arm can be pivotally coupled to the first arm support about a point located between a front end and a rear end of the first arm, the rear end of the first arm supporting the seat base. A biasing member can be connected to the seat frame, the biasing member configured to bias the seat base in the extended position.

Sensor devices closely attached to a body of a user, and walking assist devices such sensor devices may be provided. For example, a sensor device including a sensor configured to sense physical information of the user, and a support configured to provide an elastic force to the sensor such that the sensor closely attached to the body regardless pf a movement of the user, and enable the sensor to sense the physical information of the user with relative accuracy may be provided.

A portable rotation assist device is configured to reorient mobility impaired patients when they are moving from one location to another such as from a vehicle seat to a wheelchair. The rotation device is placed on the floor or ground between the two positions. The patient stands or can be assisted to stand on the platform on top of the device. The platform is then rotated to a second position to transfer the patient. Rotational movement and torque is provided by an onboard battery and compact motor acting through gears incorporated into the rotating platform. Choice of rotation direction and actuation of start and stop is provided by a wireless remote control. Remote control buttons are configured so they must be held down during rotation and rotation stops upon button release.
