A conveyance for surmounting obstacles which includes a first ground engaging arrangement, and a second ground engaging arrangement, and the first and second ground engaging arrangements are operable to move in an alternating sequence of movements to enable the conveyance to surmount obstacles. The conveyance is statically balanced alternately by one then the other of the ground engaging arrangements throughout the sequence of movements. Each ground engaging arrangement includes a forwardly disposed portion and a rearwardly disposed portion which are spaced apart from one another. Each ground engaging arrangement further includes an obstacle accommodating region located between the forwardly disposed portion and the rearwardly disposed portion which can accommodate a portion of an obstacle being surmounted during use.

The present invention relates to a wheelchair footrest 1, comprising a continuous foot support 10 or two separate foot supports 10 for supporting the feet of a user; and at least one lighting means 20; wherein said lighting means 20 is fixedly arranged on at least one of said foot supports 10 to illuminate at least a floor area 40 on a front side 102 of said wheelchair 100; and the lighting means 20 comprises an LED strip which is fixedly arranged on the underside 12 of the at least one foot support 10, and wherein the LED strip has a length BL which extends over at least 50% of the width B of the at least one foot support 10. The present invention relates also to a wheelchair 100 comprising a corresponding wheelchair footrest 1.

A power assist wheelchair includes a wheel, an electric motor that drives the wheel, an encoder that detects rotation of the electric motor, and a control device that controls the electric motor. The control device includes a total torque value calculator that calculates a total torque value based upon only a detection signal of the encoder, an assist torque value calculator that calculates an assist torque value based upon an output current of the electric motor, a manual torque value calculator that calculates a manual torque value based upon a difference obtained by subtracting the assist torque value from the total torque value, and a target current determiner that determines a target current of the electric motor based upon the manual torque value.

Embodiments described herein are directed to a wheelchair system that includes a wheelchair and an exoskeleton. The wheelchair includes a frame, a pair of armrests coupled to the frame, and a control unit. The pair of armrests movable between an attached position and a detached position. When in the attached position, each one of the pair of armrests are coupled to the frame and when in the detached position, each one of the pair of armrests is removed from the frame. The exoskeleton is communicatively coupled to the control unit via a cable extending between the exoskeleton and the control unit. The exoskeleton being releasably coupled to at least a portion of the frame of the wheelchair. The wheelchair system is translatable between a wheelchair mode and an exoskeleton mode such that, when in the exoskeleton mode, the control unit provides electrical power and control signals to the exoskeleton.

This vehicle (2) usable by a physically handicapped or able-bodied person, in particular for athletic or recreational activities, comprises a seat (4) made from monobloc plastic material and at least two main wheels (6), the seat (4) comprising a seat bottom (40), a backrest (42) and lateral rims (43). The seat (4) has a cavity (18) extending below the backrest (42) and the seat bottom (40) and an opening passing through the seat (4) between the cavity (18) and a rear part of the backrest (42), the cavity (18) and the opening being intended to accommodate a backrest of a seat (4) of a second identical vehicle positioned below said vehicle (2), such that at least two identical vehicles (2) are stacked stably one on top of the other.

Provided is a lightweight and inexpensive wheelchair that can be easily operated with either a right or left hand. The wheelchair according to the present invention is provided with; a pair of handrims having a first portion and a second portion; a drive mechanism for transmitting a first rotational force generated by the first portion on one side to a wheel on another side, and for transmitting a second rotational force generated by the first portion on the other side to a wheel on the one side, wherein the drive mechanism includes an axle on the one side, an axle on the other side connected to the axle on the one side via a rotary shaft, a first two-way clutch located on the axle on the one side, and a second two-way clutch located on the axle on the other side.
