A seat is disclosed herein having a backrest, a base for receiving a posterior of a human user, and an incline adjuster having a shaft, a lever, a follower, and a rack the shaft being moveable to swing the lever to cause a follower into or out of locking engagement with the rack, an arrangement being such that when the follower is in an unlocked disposition the rack can move to adjust an incline of the backrest and the base.

A wheelchair can comprise: a frame comprising an upper portion and a lower portion that is coupled to the upper portion so that the upper portion is vertically adjustable with respect to the lower portion. A pair of drive wheels can be coupled to the frame. A plurality (e.g., a pair) of casters are coupled to the frame. Each caster can have a respective swivel axis. At least one caster of the plurality of casters can be configured to be locked to prevent swiveling about its respective swivel axis and unlocked to enable swiveling about its respective swivel axis.

An elevation-type armrest includes a driving assembly and a cushioning assembly. The driving assembly includes a worm, a crank, an axle, a shaft, a worm gear, two toothed wheels and two pinions. The crank is connected to the worm. The axle extends perpendicular to the worm. The worm gear is connected to the axle and engaged with the worm. The first toothed wheel is connected to the axle. The shaft extends parallel to the axle. The second toothed wheel is connected to the shaft and engaged with the first toothed wheel. The pinions are connected to two ends of the shaft. The cushioning assembly includes a supporting tube connected to two racks. Each of the racks includes a toothed portion movably located in a corresponding one of the cylinders and engaged with a corresponding one of the pinions.

Provided is a robot. The robot includes a main body which is provided with a traveling wheel and in which an opening portion is defined in a top surface thereof, a seat configured to cover the opening portion at an upper side of the opening portion, an elevation mechanism disposed within the main body, the elevation mechanism being configured to elevate the seat with respect to the main body, and a gap cover configured to be elevated together with the seat, the gap cover being configured to cover a gap between the seat and the main body. The seat includes a seat base to which the gap cover is connected and which is inserted into the opening portion and a seat pad configured to cover the seat base at an upper side of the seat base, the seat pad being disposed above the main body.

Provided is a robot. The robot includes a main body in which an opening portion is defined in a top surface thereof, a seat configured to cover an upper side of the opening portion, a traveling wheel protruding downward from a bottom surface of the main body, a backrest connected to the seat, an opening defined in a front surface of the main body, a foot supporter protruding forward from the main body through the opening, and a pair of arm supporters connected to both sides of the seat, respectively.

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.

A mobile body (1A) includes: a base body (3) tiltably assembled to a movement operation section (2) that can move on a floor surface; an occupant riding section 6 installed to the base body (3) by a connection mechanism (4); an auxiliary ground contact section 7 connected to the occupant riding section (6) and in contact with the floor surface in a slidable or rollable manner when a tilt amount of the occupant riding section (6) with respect to the floor surface increases to a predetermined amount; and a control device (80) which controls the movement of the movement operation section (2) to stabilize the attitude of the mobile body (1A). The connection mechanism (4) elastically rocks the occupant riding section (6) with respect to the base body (3) according to the movement of the center of gravity of a user P riding on the occupant riding section (6).

A wheelchair having a tiltable occupant-support assembly, a powered drive system for adjusting the degree of tilt, and a control system for varying the degree of tilt in a programmatic automated fashion. The wheelchair is programmed or programmable to vary the degree of tilt, and therefore the wheelchair's occupant, automatedly. The wheelchair may provide pre-set ranges of seating angles and durations of time at each angle of tilt. The wheelchair thereby allows for reliable off-loading of the occupant's weight from pressure points, to avoid pressure ulcers, and does so programmatically so as to reduce the burden on healthcare staff and professionals while also ensuring adherence with prescribed tilting schedules.
