  • the chair may include a preferably removable hoop, and possibly a soft top, and / or has its reclining and / or swivel seat.
  • the roll bar can serve as means of gripping, holding and / or positioning of the hands, and of a fixing structure for a hood (for example a hood for protection against rain).
  • the seat is tilted for example by means of the actuator type.
  • the chair is electric, in particular the batteries being arranged on a rear platform and in front of the coupling means, or else under the chair.
  • the wheelchair is electric and has a weight of at most about twenty kilograms, preferably at most 20 kg, in particular due to the choice of materials, a refined chassis and the number of wheels.
  • the invention also relates to a method of transporting the aforementioned wheelchair of the invention and without using the chair, the method comprising a step of raising the chair, for example of manual lifting of the chair, and a step of coupling / arrangement of the coupling means of the chair in cooperation with a vehicle hitch, in particular a vehicle hitch ball.
  • the chair is attached directly to the hitch. In the coupled position of the chair on the vehicle hitch, the chair is high and at a distance from the ground. The chair does not touch the ground. The chair is in the carried position and is raised (off the ground, without its wheels touching the ground); it can then be transported.
  • the method includes a step of locking the coupling of the chair on the hitch.
  • the method may include a step of protecting the chair, in particular against bad weather, by covering it with a protective cover.
  • the term “height”, the qualifiers “upper”, “lower”, are used in the context of an installation of the armchair resting by its wheels on a horizontal flat floor.
  • the terms “front” and “rear” are understood with respect to the direction of movement of the chair when a user is installed in the chair.
  • the terms “lateral” and “laterally” qualify elements positioned on the sides of the chair, not at the front or rear.
  • the wheelchair 1 according to the invention illustrated in the figures is preferably an electric wheelchair. It is intended according to the invention to be mounted directly on a vehicle hitch as illustrated in the figure 3 .
