Definitions

  • the present invention relates to a chair adapted for use by handicapped persons and comprising a chassis supporting a seat and a back support, which has at least one lateral armrest.
  • Document GB 1 368 134 discloses a chair for handicapped persons according to the preamble of claim 1.
  • the trunk supports according to this document are adjusted and fixed by set screws, which do not allow a quick release or a simple return to a previous holding position.
  • the object of the present invention is to eliminate the problems mentioned above and to provide a chair adapted for use by handicapped persons, which has support arrangements above the arm rests, so that also very gravely handicapped persons can sit steady in the chair without falling over to either side.
  • This object is achieved by virtue of a device recited in claims 1 and 2.
  • the back support exhibits trunk supports which project from both of its sides, can be swung towards and from each other and fixed in their position. They can be brought into positions matching the shape of the body with the aid of control devices connecting them with the back support. Adjustment of their position vertically is carried out by means of vertically oriented rods, located at the back rest, and along which the trunk supports can be fixed. The rods are part of a first control device.
  • the pivoting movement of the trunk supports in a direction to and from the person sitting in the chair is carried out with the aid of a second control device, whereby the pivoting movement can be halted in a determined adjustment position matching the body of the user.
  • the trunk supports can be temporarily released from that position by actuation of special locking means.
  • the curved support members, constituting the trunk supports are likewise adjustable in the horizontal direction to match the user's body. Since the trunk supports can, by use of the locking means, conveniently be released in connection with the person taking place in the chair or leaving it, they do not, when not in use form any obstacle.
  • Numeral 1 in Fig. 1 is a chair of the type now available in the market and having a chassis 2, a seat 3 and a back support 4.
  • the chair 1 does also, at each side of the seat 3, have arm rests 5 and 6, which are adjustable in the vertical direction.
  • This chair does also include a braking deice 7 and a brake control lever 8.
  • Figs. 2-4 show a chair of the type mentioned above which is provided with pivotable trunk supports 9 and 10, projecting from each side of the back support 4 and pivotable to and from each other. Trunk supports 9 and 10 are vertically adjustable by means of a first control device 11 and by means of a second control device 12 adjustable towards the body of the person sitting in the chair 1 to a preset, desired position offering a safe holding of the body. The fixation of trunk supports 9 and 10 in that position close to the body is attained with the aid of a locking member 13 which, when released, permits that each trunk support can be swung out when a person shall sit down in the chair or rise to leave it. As appears from Figs.
  • trunk supports 9 and 10 are constituted by a padded and somewhat curved support member 14, which matches the body contour of the user.
  • the member 14 is mounted on a vertically extending guide rod 15 which is secured to the back support and along which is displaceable a holder 16 comprising a vertical position adjustment member 17 which together with the guide rod 15 forms said first control device 11.
  • the second control device 12 is constituted by a locking core 18, which is mounted in the vertical position adjustment member 17 of the holder 16 and is shown more in detail in Figs. 8 and 9.
  • the locking core 18 is provided with a hole 19 and is located inside an orifice 20 in member 17, which in turn is swingably mounted in a fork-shaped portion 21 of holder 16.
  • the portion 21 does also have an opening 25 for the locking member 13 and a hole.
  • a screw 22 is arranged to engage a groove 24 in the locking core 18.
  • Locking core 18 does also have at least one locking hole 23 cooperating with the locking member 13 for release and/or fixation of the related trunk support 9;10 in a rotational position.
  • Figs. 8 and 9 show a magnified view of the locking core 18 mounted at the end of holder 16 inside the fork-shaped portion 21.
  • the support member 14 is mounted horizontally displaceable in the holder 16 so that it can be brought into a position at a suitable distance from the back support 4, where is locked by use of a socket head cap screw 27.
  • trunk supports 9 and 10 When the chair is used, one or both of trunk supports 9 and 10 is swung to a position shown in Fig. 4 after a preceding release trunk support 9 effected by means of locking member 13 which is then caused to leave hole 23 in the locking core 18 by a downward pulling movement.
