Definitions

  • the present invention relates to a motorised wheelchair comprising a chassis, which is mounted on wheels, and a seat fixed on a seat frame mounted on the chassis so as to be movable between a driving position and a service position allowing access to the chassis.
  • a motorized wheelchair of the above mentioned type is known from GB 2269143 .
  • the seat of the wheelchair described in this prior art document is mounted on the chassis so as to be pivotable about a generally horizontal axis located in front of the chassis.
  • Such an arrangement is useful with regard to servicing or installing/removing the battery, or the motor(s) which are located in the chassis, under the seat when the same is in the driving position.
  • the arrangement described in this document allows access to the motors and battery located in the chassis, it has several disadvantages. In particular, when the seat is pivoted, any object or accessory present in the seat and not securely fixed to the seat will fall from the seat. Further, such an arrangement is only suitable for a wheelchair where the legrest is secured to the chassis itself, but not for wheelchair where the legrest is secured to the seat.
  • the motorised wheelchair according to the present invention concerns a motorised wheelchair as defined in claim 1. Important features of the wheelchair according to the present invention are further defined in the claims depending on claim 1.
  • the wheelchair represented on Fig. 1 comprises a seat 1 secured to a seat frame 2 mounted on a chassis 3, said chassis being itself mounted on wheels 4.
  • the legrest 26 is secured to the seat frame 2.
  • the seat frame 2 mainly comprises two longitudinal elements 5 and 6 and two transversal elements 7 and 8. Said seat frame is mounted on the chassis 3 so as to be movable between a driving position as shown on Figs 4 and 8 and a service position as shown on Fig. 7 allowing access to the battery and motors located in the chassis.
  • the seat frame 2 is connected to the chassis through a trapezium type device comprising two pairs of lateral members 18, 21. Since the structure of the seat frame and of the chassis is symmetrical with regard to a medium longitudinal vertical plan of the wheelchair, only one side of the device, i.e. the side situated on the left in Figs 4 to 7, will be described.
  • the trapezium type device comprises two lateral members 18, 21, said first lateral member 18 being on one of its ends 20 hinged to the chassis 3 at a location corresponding approximately to the middle of the length of the seat frame when the seat frame is in the driving position of the seat, and on its other end 19 hinged at the free end of an element 24 protruding out of the seat frame 2 in the prolongation of the element 7.
  • the second lateral member 21 is hinged on one of its ends 22 on the lateral element 6 of the seat frame, at about one third of its length from the rear part of the seat frame, and on its other end 23 is hingedly mounted on the ends of a transversal horizontal bar or tube 15.
  • Said transversal horizontal bar or tube 15 is in its turn hingedly mounted to be translated in rotation parallely to an axis 16, 16' parallel to said horizontal bar or tube 15, and which can be secured to said chassis or to a tilt mechanism 17 of the seat, when the seat is provided with such a tilt mechanism.
  • the trapezium type device allowing the displacement of the seat from a driving position to a service position is arranged in a manner to avoid any increase of height of the wheelchair when the seat is in the driving position.
  • the lateral members 18 and 21 do not move in a same plan, since the spaced apart of the two longitudinal elements 5 and 6 of the seat frame, on which are hinged the lateral members 21 is smaller than the internal width of the chassis.
  • the locking of the seat frame in the driving position of the seat illustrated in Figs 4 and 8 is obtained on the one part by the action of two claws 11, 11' fixed to the front element 8 of the seat frame 2, said claws being clampled on the horizontal bar or tube 15, and on the other part by the action of two screws 25, 25' which fix the seat frame to the chassis through the transversal axis 30 (see also Fig. 4).
  • the lateral members 18, 21 will pivot toward the above, bringing the seat frame again in a substantially horizontal position (Figs 6 and 10) to reach a final advanced position as shown in Fig. 7, allowing an easy access to the batteries and motor(s) located into the chassis.
  • the forward movement of the seat is facilitated by two gas springs 24, 24' fixed to the internal side of the chassis and acting on the lateral members 18.
  • the seat frame Since, apart from the first reclining movement of the seat in the first step of the displacement, the seat frame remains substantially horizontal during the whole movement (that is why the movement of the seat has been called a slightly curved translation movement), avoiding any important forwards inclination of the seat.
  • the displacement movement of the seat can be easily handled by a single person, said gas springs ensuring the positioning of the seat in the service position once displaced.
  • the device is provided with a safety means for disabling the drive mode of the wheelchair when the seat is removed from its driving position.
  • a safety means for disabling the drive mode of the wheelchair when the seat is removed from its driving position.
  • Such safety means can comprise a micro switch or any other suitable switch placed on any suitable part of the seat frame.
