A tilting mechanism for a chair that has a seat frame, a seat and a chair back. The tilting mechanism has a track path along which the seat tracks between an upright sitting position and a reclined position. The chair back tracks concurrently between a first position when the seat is in the upright sitting position and a second inclined position when the seat is in the reclined position. The inclination of the chair back increases at a greater rate than the inclination of the seat as the seat moves between the upright sitting position and the reclined position.

A swing chair includes a base, a seat, and a driving frame. The seat is disposed above the base. The driving frame is disposed between the base and the seat. The driving frame includes a first fixing base, a first shaft, a second fixing base, a second shaft, a first driving assembly, and a second driving assembly. The first fixing base is fixed to the base. The first shaft is rotatably connected to the first fixing base. The second fixing base is fixed to the seat. The second shaft is connected to the first shaft and the second fixing base is rotatably connected to the second shaft. The first driving assembly is configured to drive the first shaft to rotate with respect to the first fixing base. The second driving assembly is configured to drive the second fixing base to rotate with respect to the second shaft.

An assistance chair assembly includes a base and a chair is positioned on the base. Two upright boards are perpendicularly connected to the top of the base, and two extension portions extend from the rear end of the base. The chair includes two front legs and two rear legs. The front legs each have a curve slots which allows the chair to be is pivotable about the bolts extending through the rear legs of the chair. The weight center of the chair is not moved beyond the two extensions portions of the base when the chair is pivoted toward the two extensions portions.

A wheelchair includes a frame, a seat attached to the frame, a first forward wheel on a first side of the frame and a second forward wheel on a second side of the frame, a first rearward wheel on the first side of the frame and a second rearward wheel on the second side of the frame, a first drive wheel on the first side of the frame positioned intermediate between the first forward wheel and the first rearward wheel and a second drive wheel on the second side of the frame positioned intermediate between the second forward wheel and the second rearward wheel, and actuators to independently control the vertical position of the first forward wheel relative to the frame, the vertical position of the second forward wheel relative to the frame, the vertical position of the first rearward wheel relative to the frame, the vertical position of the second rearward wheel relative to the frame, the vertical position of the first drive wheel relative to the frame and the vertical position of the second drive wheel relative to the frame.

Disclosed is a manual wheelchair having a rotating seating area thereby providing a gradation of seating options between an upright and a tilted position. The rotation of the seating area of the disclosed wheelchair from an upright to a tilted position is independent of the position of provided push handles.

A wheelchair is disclosed that is especially designed for caretakers of severely handicapped patients. The wheelchair is pushed in a seat-backward direction that allows the caretaker to see the patient face-to-face for better evaluation of the patient's comfort status during movement of the wheelchair.

The present disclosure relates to atilt assembly (1) for a powered wheelchair (15), comprising: an elongated base member (3) provided with an axial channel, a lifting member (5) configured to be received by the base member (3) and to move rectilinearly in the channel, between a retracted position and an extended position relative to the base member (3), a tilt frame (7) pivotally connected to the lifting member (5), the tilt frame (7) being configured for mounting a seat assembly (21) thereto, and an actuator arm (9) pivotally connected to the base member (3) and to the tilt frame (7), the actuator arm (9) being configured to be actuated between a retracted actuator position and a fully extended actuator position, wherein the tilt frame (7) is configured to obtain a perpendicular orientation relative to a central axis (11) of the lifting member (5) when the lifting member (5) is in the retracted position and the actuator arm is in the retracted actuator position and to be inclined relative to the central axis (11) when the lifting member (5) is in an extended position and actuator arm is in the retracted actuator position, to thereby provide a tilt functionality.

A mechanism for a scissor lift (1) or for a tilt system (21) is disclosed, which mechanism comprises a lower frame (2), an upper frame (3), a controlling arm (6), a lifting arm (7) and a power source (8) and is configured in such a way that an extension of the length of the power source (8) causes the lifting arm (7) to pull a fulcrum (14) on the first lever arm (4) or a fulcrum (22) on the second lever arm (5) in a direction away from the lower frame (2), which, in turn, causes the lowermost end of the second lever arm (5) to be pulled towards the lowermost end of the first lever arm (4) and at least one end of the upper frame (3) to be forced away from the lower frame (2). The power source (8) will provide a substantially constant power throughout the motion when the mechanism being used in a scissor lift, whereas, the power source (8) may give maximum power in the beginning of the motion and less power later on in a tilt system. Furthermore, a scissor lift (1) and a tilt system (21) each comprising such a mechanism and a wheel chair comprising such a scissor lift and/or such a tilt system are disclosed.

The present disclosure relates to a tilt assembly (1) for a powered wheelchair (15), comprising: an elongated base member (3) provided with an axial channel, a lifting member (5) configured to be received by the base member (3) and to move rectilinearly in the channel, between a retracted position and an extended position relative to the base member (3), a tilt frame (7) pivotally connected to the lifting member (5), the tilt frame (7) being configured for mounting a seat assembly (21) thereto, and an arm (9) pivotally connected to the base member (5) and to the tilt frame (7), wherein the tilt frame (7) is configured to obtain a perpendicular orientation relative to a central axis (11) of the lifting member (5) when the lifting member (5) is in the retracted position and to be inclined relative to the central axis (11) when the lifting member (5) is in the extended position, to thereby provide a tilt functionality.

A first transport apparatus includes a deck for supporting a patient thereon and a lift mechanism supporting the deck. The deck is removable from the lift mechanism for use as a second transport apparatus or part of a second transport apparatus. The first transport apparatus further includes an electrically powered device at the first transport apparatus, and a user input device for wireless control of the electrically powered device, which is operable at or near the first transport apparatus and the second transport apparatus.
