A seat assembly for wheelchair of the type having a structure expandable from a contracted condition to an expanded position comprises a pair of tubular members connected to the structure. Each tubular member has a main tubular body, a secondary tubular body parallel to and inside the main tubular body, and an elongated slit extending along both the main tubular body and the secondary tubular body and common to both the main tubular body and the secondary tubular body. The slits open into an inner channel of the secondary tubular body. The main tubular body and the secondary tubular body form a hollow integral piece of composite material. A panel, e.g., of non-rigid material has rods on its opposite edges, the rods having a diameter smaller than that of the secondary tube and larger than a width of the slit to be held captive in the secondary tube, whereby the panel extends through the slit.

A portable wheelchair is collapsible for ease of development, handling and transport, while also providing a front steer configuration and a rear steer configuration.

A wheelchair is provided which includes driving wheels, side frame, footrest arms, and footrest plates. The driving wheels are rotatably coupled to the exterior sides of the side frames. The footrest arms are movable between arm unfolded and folded positions. Each of the footrest arms is pivotably coupled to an arm pivot shaft. The arm pivot shaft is positioned on the exterior side of each of the side frames in front of each of the driving wheels. The footrest plates can support user's feet. Each of the footrest plates is coupled to the fore end of each of the footrest arms. The distance between the fore ends of the footrest arms in the arm unfolded position is smaller than the distance in the arm folded position.

A folding wheelchair is disclosed having a frame with two side portions, a seat and a folding mechanism. The folding mechanism has coupling connections, pivoting connections and a cross-strut with two bars crossing at a pivot point. First ends of each of the cross-strut bars are mounted rotatably on the side portions of the frame via the pivoting connections. Second ends of each of the cross-strut bars are releasably mounted on the other of the two side portions of the frame via the coupling connections. A distance between the frame side portions may be modified if the cross-strut bars second ends are released from the frame side portions. The cross-strut bars are pivoted relative to each other about the pivot point. The cross-strut extends from the first ends to the second ends of the bars in a cross-strut direction which, in the operating position, extends substantially along the seat.

The present invention provides an assistive mobility device convertible between a rollator mode and a transport chair mode.

A small electric vehicle includes: a vehicle body that has a forward and backward direction, and a width direction; left and right driving wheels provided apart in the width direction of the vehicle body; left and right motors connected so as to respectively transmit power to the left and right driving wheels; an operation unit that includes a joystick-type operation piece; and a control unit for controlling the left and right motors according to an amount of operation on the operation piece, wherein the control unit is configured to execute deceleration and stop control when the operation piece is returned to the neutral position during travel, and execute rapid stop control irrespective of an amount of operation in left and right directions when the operation piece is tilted backward during forward travel at a speed equal to or greater than a predetermined threshold.

A folding wheelchair with an excretion device has a foldable chair frame, a supporting device on the chair frame under a seat which is also foldable together with the chair frame, a wash device for cleansing and a wipe device for wiping. The folding wheelchair allows its user to perform excretion and cleansing by himself without leaving the wheelchair, saving the self-esteem for the users and reducing the burdens for the caregivers.

An adjustable wheelchair and components thereof are provided. The wheelchair may include a first chassis connected to a first wheel on a first side of the wheelchair. The first chasses may include a first strut configured to laterally translate while supporting a seat. The wheelchair may further include a second chassis connected to a second wheel on a second side of the wheelchair. The second chasses may include a second strut configured to laterally translate while supporting the seat. A jack may be connected to the first chasses and second chasses. The jack may operatively cause the first and second chassis expand away from each other and contract toward each other to vary a width between the first side and second side of the wheelchair.

A small electric vehicle includes: a vehicle body that has a forward and backward direction, and a width direction; left and right driving wheels provided apart in the width direction of the vehicle body; left and right motors connected so as to respectively transmit power to the left and right driving wheels; an operation unit that includes a joystick-type operation piece; and a control unit for controlling the left and right motors according to an amount of operation on the operation piece, wherein the control unit is configured to execute deceleration and stop control when the operation piece is returned to the neutral position during travel, and execute rapid stop control irrespective of an amount of operation in left and right directions when the operation piece is tilted backward during forward travel at a speed equal to or greater than a predetermined threshold.

Disclosed herein is a backrest interlocking type frame for a foldable wheelchair. The backrest interlocking type frame includes: a seat frame which includes a first horizontal bar and a second horizontal bar spaced apart from each other at a predetermined interval and arranged at the top and the bottom of the seat frame, a first mounting member, a second mounting member, and a third mounting member mounted between the first horizontal bar and the second horizontal bar to be spaced apart from one another, a first bracket mounted on the first mounting member and a second bracket mounted on the second mounting member; a backrest frame which includes a first vertical bar and a second vertical bar formed integrally, wherein one end of the first vertical bar is rotatably mounted on the third mounting member of the seat frame through a first hinge portion, and both ends of a rail are fixed between the second mounting member and the third mounting member of the seat frame; a horizontally foldable frame rotatably mounted on the first bracket and the second bracket of the seat frame; and a transfer block mounted on the rail to move along the rail, wherein one end of a retractor is rotatably mounted on the transfer block through a third hinge portion, the other end of the retractor is rotatably mounted on the second vertical bar of the backrest frame through a second hinge portion, so that the horizontally foldable frame is operated to be folded when the backrest frame is folded downwardly, thereby reducing the overall width of the seat frame.
