A lift assist device preferably includes a pair of lift units and a battery. Each lift unit preferably includes a linear actuator, a lift projection, a top bracket and a bottom bracket. A screw sled extends from one side of the linear actuator. An end of a lift projection is secured to the screw sled. One end of the top bracket is attached to a top of the linear actuator. One end of a bottom bracket is attached to a bottom of the linear actuator. The top and bottom brackets will be different depending on whether they are attached to rollators, wheelchairs, motorized wheelchairs and motorized scooters. The lift assist device may be used to help lift a user from a chair adjacent the rollator, wheelchair, motorized wheelchair or motorized scooter, or when the user is seated in rollator, wheelchair, motorized wheelchair or motorized scooter.

A multi-cell inflatable jack includes a plurality of jack elements. Each of the plurality of jack elements includes a body having a predetermined perimeter shape and defining a perimeter chamber and a central chamber. A valve is coupled to the body and configured to provide air flow to one of the perimeter chamber or the central chamber. A plurality of flow control stringers are located between the first chamber portion and the second chamber portion and are configured to control an air flow rate into each of the perimeter chamber and the central chamber. At least one fastener is formed on the body and configured to attach the jack element to at least one additional jack element in a multi-cell stack.

A caring device includes an adjustment command section configured to give a command for an adjustment of a standing start position of a support member, a standing operation command section configured to give a command for assistance of the standing operation using the support member, and a control device. The control device perform a cooperative operation of the first arm and the second arm so that the support member moves in an up-down direction when a command of the adjustment command section is received. The control device performs a cooperative operation of the first arm and the second arm so that a reference position of the support member moves along different movement trajectories in accordance with the standing start position adjusted by the command of the adjustment command section when a command of the standing operation command section is received.

Various aspects of the present disclosure are directed to adjustable chairs with a plurality of adjustment points to facilitate enhanced user mobility and increase a user's physical activity through guided exercises and stretches. In one example embodiment, a chair is disclosed including a lifting mechanism to assist a user from a seating to a standing position and facilitates standing stretches through a number of motion and rotation mechanisms.

An adjustable chair, belonging to the field of office furniture, comprising a base frame. A chair back is disposed at the rear end of the base frame. A lifting assembly is disposed on the base frame and provided with a seat, and comprises a bottom frame and a top frame formed with sliding slots. The seat is disposed on the top frame and the seat angle can be adjusted. By adjusting the height of the chair through the lifting assembly and adjusting the rotation angle of the seat, users not only can stand and lean against the chair, but also can normally sit on the chair.

A sit assist device (1) comprising a base (2) adapted to be supported by a seating surface, and a sitting platform (3) hingedly connected to the base (2) and movable between a raised position and a lowered position to assist a user to sit down onto and to stand up from the sitting platform (3). A primary biasing means (4) provides a primary resilient bias to resiliently bias the sitting platform (3) from the lowered position to the raised position over an operating range, thereby moving the sitting platform (3) from the lowered position to the raised position over the operating range as the user stands up from the sitting platform (3) and slowing the movement of the sitting platform (3) from the raised position to the lowered position over the operating range as the user sits down onto the sitting platform (3). A secondary biasing means (5) provides a secondary resilient bias to supplement the primary resilient bias over a portion of the operating range adjacent the lowered position.
