Definitions

  • the invention relates to a wheelchair for the disabled with a movable and lockable seat surface about a horizontal first axis of rotation and a lower arranged, horizontally offset from the seat surface and movable about a further horizontal axis and lockable foot support surface.
  • Such a wheelchair is known from DE-PS 25 58 669.
  • a wheelchair with universal adjustment options which has a tiltable and height-adjustable seat shell and a footrest which can be changed in position relative to the seat shell, so that the user's feet can be fixed in a wide variety of positions.
  • a wheelchair with a footrest and a legrest is known from US Pat. No. 3,902,758. Although these supports can be moved so that an alternate use of one support is not hindered by the other support, it is not possible to adjust the seat and to determine the foot or leg support in a user-specific position.
  • the object of the invention is to develop a wheelchair for the disabled in such a way that the user of the wheelchair is not exclusively bound to the sitting posture.
  • This object is achieved according to the invention in a wheelchair of the type mentioned at the outset in that the seat surface and the foot support surface can be moved from a first, approximately horizontal position (seat position) with a vertical distance into a second position (knee position) in which the seat surface forward and downward and the foot support surface are inclined towards each other and the vertical distance between the two is reduced, and in which the foot support surface serves to support the shins or knees.
  • the object is achieved in a wheelchair of the type mentioned in that an additional lockable knee support surface is provided which serves to support the shins or knees and which can be moved into a rest position when not in use, which is an unobstructed Use of the foot support surface allows, and that the seat surface is movable from a first, approximately horizontal position (seat position) to a second position (knee position), in which the seat surface towards the front down and the additional knee support surface towards each other towards the top are inclined.
  • the advantages of the invention are, in particular, that the user can use the wheelchair either in a seated or kneeling position and thus there is variety.
  • the straight posture of the upper body is supported by shifting the body weight from the seat surface to the knee support surface and thus relieves the spine, so that the risk of consequential damage from the one-sided load on the spine is significantly reduced by the only possible sitting position so far .
  • the kneeling posture increases the freedom of movement for the upper body, so that activities that could not be done in a sitting posture, or only with great difficulty, are now possible from a wheelchair or are much easier to accomplish.
  • a so-called active armchair is already known (DE-Z :: Med. Orth.technik, 109 (1989), H. 6, pp. 239 to 244), which enables the user to kneel and the seat and knee support surface relative to one another distance and inclination can be adjusted gradually.
  • a disadvantage of this active armchair is that it is not a wheelchair; such an active armchair cannot be used for the disabled who are dependent on a wheelchair. In addition, this active armchair cannot be adjusted from the knee position to a conventional sitting position.
  • the wheelchair according to the invention for the disabled to change the inclination of the seat surface and the support surface used to support the knees independently of one another.
  • the knees can be set as conveniently as possible for wheelchairs used by different people (e.g. in hospitals) and adapted to their requirements.
  • the seat surface and the support surface used to support the knees can be adjusted jointly by a swivel mechanism. This makes it possible to switch the wheelchair from the sitting position to a predefined knee position with very little effort.
  • the seat and the support surface used to support the knees can be moved either by muscle power or by electric drives. This makes it possible to largely adapt the adjustment option to the needs of the user, which can vary greatly depending on the extent and severity of the disability.
  • Existing wheelchairs can also be converted accordingly, since wheelchairs that are powered by muscle power also require adjustment of the seat and support surface by muscle power or, in the case of electrically powered wheelchairs, a voltage source for moving the seat surface and the support surface is available anyway stands.
  • the seat surface and the support surface used to support the knees are rotatably supported and are supported by Wire tensioner changed in its angle of inclination.
  • Wire tensioner changed in its angle of inclination.
  • the support surface used to support the knees is padded on at least one side.
  • the padding increases the comfort of the seat considerably on the one hand, and on the other hand it reduces the strain on the skin if the user stays in the knee position for a long time.
  • the foot support surface can be moved out of the foot area to make it easier to get out of the wheelchair. This is achieved in particular by a foot support surface which is divided in the middle along the direction of travel and whose two individual surfaces can be folded up. As a result, the level that is otherwise present when the user gets up is eliminated. Rather, it is then possible that the user can put his feet directly on the floor and leave the wheelchair without any problems.
  • the backrest can be folded back to further increase the freedom of movement of the upper body in the knee position.
  • the wheelchair according to FIGS. 1 and 2 has a seat surface 1 and a foot support surface 2 which is horizontally offset from the seat surface 1.
  • the foot support surface 2 is pivotally mounted in pivot bearings 7 and can be moved from the sitting position, in which it lies essentially horizontally, into a knee position 2 '(indicated by dashed lines), in which the user of the wheelchair is with his knees or shins can rely on it.
  • the seat 1 is moved about a first axis of rotation 8 from the approximately horizontal position to a position 1 'which allows comfortable kneeling and in which the vertical distance a (sitting position) is reduced to the vertical distance a' in the knee position .
  • Figures 1 and 2 are to adjust the seat 1 and the foot support surface 2 in length adjustable wire tensioner 5, 5 '; 6, 6 'provided with which the inclination of the surfaces 1, 1'; 2, 2 'can be set.
  • a second axis of rotation 9 allows the backrest 4 to be folded back in order to obtain more freedom of movement for the upper body.
  • the wheelchair according to FIGS. 3 and 4 has a seat 1, 1 ', foot support surfaces 2a, 2b and an additional knee support surface 3, 3'.
  • the knee support surface 3 can be pivoted about a third axis of rotation 10 into a knee position 3 ', in which it is also inclined towards the seat surface 1, 1' in such a way that a comfortable kneeling is possible.
  • the knee support surface 3 In the sitting position, the knee support surface 3 is pivoted into a position in which it allows unhindered use of the foot support surfaces 2a, 2b.
  • the backrest 4 can in turn be folded back about the second axis of rotation 9 in order to increase the freedom of movement of the upper body.
  • the surfaces 2, 2 '; 3, 3 'for supporting the knees can be provided with padding (not shown).
  • the embodiments shown in FIGS. 1-4 can also be equipped with a swivel mechanism (not shown) which is actuated via a lever which is arranged laterally next to the seat surface and the inclination of the seat surface 1, 1 'and the surface used to support the knees 2, 2 '; 3, 3 'changed simultaneously.
  • pivoting mechanisms for adjusting the inclination of the seat and support surfaces can be driven instead of being driven by muscle power via electrically operated servomotors (not shown), which likewise allow the inclination angle to be adjusted separately or jointly.
