Definitions

  • the invention relates to a mid wheel drive wheelchair, comprising a frame and a suspension unit for at least one drivable wheel element connected thereto, wherein the suspension unit comprises a first bearing arm connected to the frame for the drivable wheel element, wherein a first end of the first bearing arm is pivotably connected to the frame, wherein the drivable wheel element is rotatably mountable near a part of the first bearing arm which part is spaced apart from the first end, and wherein the suspension unit is provided with a spring and/or damper element connected to the frame for damping a pivoting motion of the first bearing arm.
  • the suspension unit comprises a front bearing arm for a front supporting wheel element.
  • the generally known mid wheel drive wheelchair comprises a frame having a driving unit.
  • a seat for a user is mounted on the frame.
  • the user has access to control means shaped as a movable handle for thereby moving the wheelchair.
  • the generally known wheelchair is provided with a total of six wheels: two front wheels, two middle wheels, and two rear wheels.
  • the middle wheels are drivable by means of the driving unit, which is connected to the control means.
  • the wheelchair is movable by driving the middle wheels.
  • the front and rear wheels are not driven, but serve as a means of supporting the wheelchair, for acquiring the required stability during a rolling movement.
  • a steering motion can be performed by driving the two middle wheels independently of one another.
  • a great advantage of the generally known mid wheel drive wheelchair is that it is able, due to the relatively central positioning of the driven wheels, to perform a relatively compact rotation motion. To this end one middle wheel is driven in the forward direction, and the other middle wheel is driven in the backward direction.
  • a drawback of the known mid wheel drive wheelchair is, that the suspension unit is configured in a relatively complex manner.
  • the complexity of the suspension unit makes the known wheelchair relatively expensive.
  • the complex suspension unit it has been shown that the stability and the comfort for the user can be improved.
  • the object of the current invention is to provide an improved mid wheel drive wheelchair, which preferably is provided with a simple suspension system, and wherein stability of the wheelchair on different surfaces and in varying circumstances is guaranteed, without at the same time losing track of the comfort of the user.
  • the invention provides a mid wheel drive wheelchair according to claim 1.
  • the suspension unit comprises a second bearing arm for a rear supporting wheel element. A first end of this second bearing arm is pivotably connected to the first bearing arm, wherein the first end of the second bearing arm is located between the spring and/or damper element and the first bearing arm.
  • the spring and/or damper element is also configured for damping a pivoting motion of the second bearing arm.
  • the first bearing arm with the drivable wheels is, by means of the second bearing arm which is hingedly connected thereto, dampingly suspended to the frame.
  • the first bearing arm is thus connected to the frame only with the first end, and connected to the second bearing arm only with the second end Damping for both the first and the second bearing arm is thereby achieved in an embodiment by means of only a single spring and/or damper element. In this manner the number of required components, and the complexity of the suspension unit are reduced.
  • both arms are dampingly connected to one another. It has been shown that this improves the stability of the wheelchair, and that the comfort of the user is therein secured. Thereby the object of the current invention is achieved.
  • a first end of the spring and/or damper element is connected to the frame, wherein an end of the spring and/or damper element which is spaced apart from the frame is directly connected to the second bearing arm.
  • the spring and/or damper element may in an embodiment engage on a part of the second bearing arm which is located longitudinally spaced apart from the first end.
  • a point of rotation of the drivable wheel element is located between the hinging point of the first bearing arm and the hinging point of the second bearing arm.
  • the hinging point of the second bearing arm is located between the point of rotation of the drivable wheel element and the spring and/or damper element.
  • the wheelchair comprises a seat element for a user which is connected to the frame.
  • the suspension system according to the invention it is possible to place the driven wheels relatively far to the front.
  • the point of rotation of the drivable wheel element is substantially located perpendicularly spaced apart from the seat element, preferably perpendicularly spaced apart from the centre of the seat element. This increases the manoeuvrability of the wheelchair, but achieves, especially during in place rotations (being a rotation motion of the wheelchair, without a translating motion) a higher level of comfort for the user, because the point of rotation then substantially coincides with the centre of mass of the user.
  • the second bearing arm is also suspended pivotably about its longitudinal axis.
  • the second bearing arm is pivotably suspended about its longitudinal axis. The number of degrees of freedom of the second bearing arm is thereby increased, by means of which an accurate following motion of the wheels across the surface is possible.

  • the suspension unit comprises a front bearing arm for a front supporting wheel element.
  • a first end of this front bearing arm is pivotably connected to the first bearing arm, which comprises the drivable middle wheel element.
  • a front spring and/or damper element is provided which is configured for damping of a pivoting motion of the front bearing arm.
  • a first end of the front spring and/or damper element is preferably connected to the frame, and an opposite end of the front spring and/or damper element is directly connected to the front bearing arm.
  • Preferably at least one front pivoting wheel element is mountable on the front bearing arm.
  • the front bearing arm is mounted to the first bearing arm near the first end of the first bearing arm, which first end is connected to the frame.
