If according to the preferred variant of each of these roles with an associated electric motor is provided, can be controlled individually by the individual Electric motors an extremely manoeuvrable seating furniture can be created. On Another advantage of such a "four-wheel drive" is the ability to overcome obstacles such as. Door thresholds, carpet edges and shaggy carpets too overcome because there are no freely rotatable and easy to lock Furniture castors are needed.
- only one can drivable roller can be provided which e.g. in the central or rear area of the seating is arranged centrally and is designed to be steerable. Also with such an arrangement, an extremely agile mobile seating created. Crossing the roller can change direction in a confined space.
- the roles can be anywhere the seating can be arranged. Only one can be used Be drivable role, or it can be several, in particular two or four, rollers with a drive.
- a single central, i.e. either with respect to the longitudinal direction and the transverse direction, drivable role provided.
- the seating furniture has four roles on, which are each arranged in a corner area of the seating, wherein two diagonally opposite rollers, e.g. the front right roller and the rear left roller, each with a drive are.
- the rollers can be attached to the side parts of the seating, for example be, either directly or via a suitable support structure.
- the or each is drivable Provide the roller with a suspension, which ensures that the respective roller remains in permanent contact with the ground. This way, for optimal traction of the mobile seating furniture.
- a further preferred embodiment proposes between each to provide a drive motor and the drive roller with a slip clutch, which serves as overload and transport protection. Damage to the Drive unit, in particular of the motor, in overload conditions or, for example then when the seating is moved by the user by hand can be safely avoided in this way.
- the drive rollers can alternatively always with the same Direction of rotation driven, but operated at different speeds become.
- the drive rollers therefore turn in when cornering the same direction, but at different speeds, in extreme cases a drive roller is stationary, e.g. when driving a sharp left turn the or each left drive roller.
