The present invention relates to an electric vehicle. The electric vehicle includes: a mobile base capable of traveling by an electromotive drive; and a battery capable of supplying electric power used in the electromotive drive. The mobile base includes: a front base having a front wheel; and a rear base having a rear wheel, the front and rear bases are configured to be capable of moving relative to each other so as to be changeable between an expanded state in which a wheelbase is expanded, and a contracted state in which the wheelbase is more contracted than in the expanded state, the front base includes a receiving portion capable of receiving the battery, and the receiving portion has a front opening formed in a front-end portion of the front base or a rear opening formed in a rear-end portion of the front base.

An electric vehicle includes: a mobile base capable of traveling by an electromotive drive; a seat including a seating portion having a sitting surface; and a battery capable of supplying electric power used in the electromotive drive. The seating portion of the seat includes a receiving portion capable of receiving the battery and arranged on a seat lower side with respect to the sitting surface. The mobile base is changeable between an expanded state in which a wheelbase is expanded and a contracted state in which the wheelbase is more contracted than in the expanded state. The seat is movable between a sitting position that the sitting surface faces a vehicle upper side in an expanded state of the mobile base, and a retracted position that the seating portion is retracted from the sitting position to a vehicle front side in a contracted state of the mobile base.

A folding electric wheelchair that provides the user an electronic driving system powered by two lithium-ion batteries that is sealed to be weatherproof, able to drive over different terrain types and slope grades on any given day whether it's raining or sunny, lightweight and portable for transportation, travel-friendly, compact in overall size when in the folded position to fit into a small space for storage. An ergonomically contoured seating that includes a bump dampening and terrain vibration system with the supporting frame pieces (34), (42), and (50) having an oval shape. The manner of how the embodiment operates to fold and unfold consists of eight specific hinge joint embodiments including: (30), (32), (38), (40), (46), (48), (58) and (64).

A lightweight collapsible frame, a plurality of wheels, at least one supporting member for supporting a patient at least partially, and at least one guiding member for guiding the movement of the transporter is provided. At least one of the plurality of wheels is mounted on the lightweight collapsible frame and at least one of the plurality of wheels is mounted on the guiding member. The guiding member and the supporting member are mounted on the frame.

An adjustable backrest is adapted for a chair frame and includes a first pivoting component, a second pivoting component, a backrest sliding assembly and a backrest connecting component. The second pivoting component is pivoted to the first pivoting component. The backrest sliding assembly is slidably disposed on the first pivoting component. The backrest connecting component is disposed between the first pivoting component and the second pivoting component. A first end of the backrest connecting component is pivoted to the backrest sliding assembly. A second end of the backrest connecting component is pivoted to the second pivoting component. The backrest sliding assembly drives the second pivoting component to pivot relative to the first pivoting component by the backrest connecting component when the at least one backrest sliding assembly slides relative to the first pivoting component, so as to support a user's back portion at different angles.

A mobile object according to the invention includes: a moving base including a front base and a rear base; a seat including a seating part and a leg part configured so as to support the seating part; and a frame disposed on the rear base, in which the leg part includes: the seating part attaching region to be attached to the seating part, the base attaching region to be attached to the front base so as to be pivotable, and a frame attaching region to be attached to the frame so as to be pivotable, the front and rear bases are movable relative to each other such that the moving base can change between the expanded state and the contracted state of the wheelbase, the pivotal movement of the leg part is interlocked with the relative movement between the front and rear bases, the frame is configured so as to cover the seating part attaching region and the frame attaching region from an outside of the mobile object in the width direction when the moving base is in the expanded state, and cover the base attaching region and the frame attaching region of the leg part from an outside of the mobile object in the width direction when the moving base is in the contracted state.

The electric vehicle according to the present invention includes a moving base capable of traveling by electromotive drive, a seat including a seating part having a seating surface and disposed on the moving base, and a back plate used as a seat back corresponding to the seating surface and disposed on the moving base, the seat can move between a seating position with the seating surface facing upward, and a retracting position with the seating part retracted forward from the seating position, the back plate can be moved between a standing-up position located rearward and upward with respect to the seating part of the seat when at the seating position, and a lying-down position located forward of the standing-up position, and the back plate includes a baggage carrier formed on a back surface facing upward when at the lying-down position and allowing baggage to be placed thereon.

A mobile object is configured so as to be capable of moving front and rear bases 10,30 object to each other in order to make a wheel base provided between the front wheels 12 and the rear wheels 32 expandable and contractible. The front base 10 moves so as to be expand and contract the tread width between the front wheels 12 in association with the expansion and the contraction of the wheel base achieved. The seating part 41 is configured so as to turn forward in association with the relative movement of the front and rear bases 10,30 in order to contract the wheel base and the tread width. The seating part 41 is configured so as to turn backward in association with the relative movement of the front and rear bases 10,30 in order to expand the wheel base and the tread width.

A multi-purpose wheelchair is disclosed herein. The wheelchair comprises a tubular frame having two support members pivotally mounted and extending upwardly from the tubular frame. The wheelchair also comprises four legs pivotally mounted and extending downwardly from the tubular frame. The wheelchair comprises further four wheels arranged such that one wheel is provided with each of the legs. The wheelchair also comprises a split-seat with an opening supported on the base. Further, the wheelchair comprises a back support extending between the two support members.

A mobile object of the invention includes: a moving base including a front wheel and a rear wheel; a seat having a seating surface; and an armrest located outward of the seating surface in a width direction of the mobile object. The armrest includes: a supporting part supported on the moving base; a body part supported by the supporting part; and a grip protruding from the body part. The armrest is configured so as to be changeable between the position of use in which a user seated on the seating surface can hold the grip with the arm positioned upward of the armrest, and the lift-up position in which the grip is positioned upward of the position of use. The grip in the lift-up position is located outward in the width direction of the mobile object with respect to the grip in the position of use.
