Definitions

  • the present invention relates to a safety device for the transport in a vehicle of a person traveling in a wheelchair.
  • Another wheelchair fixing device (FR-A-2 383 342) using two positioning hooks which are intended to be engaged in two longitudinal rails embedded in the floor of the vehicle before being hooked to the frame of the wheelchair also cannot be operated by the occupant of the wheelchair.
  • the present invention relates to a simple safety device involving only minor adaptations on a conventional transport vehicle and on conventional wheelchairs, while providing the occupants of wheelchairs, without the assistance of a guard or another person, effective protection both against the effects of the forces which occur during the normal operation of the vehicles and against the effects of shocks occurring in the event of a possible accident.
  • the safety device for the transport in a vehicle of a person circulating in a wheelchair, comprises two fastening members connected on either side to the chassis of the wheelchair, between the front wheels and the rear wheels of the chair, said two hooking members being each provided at its lower end with a means which can be brought to cooperate with a retaining member fixed to the floor of the vehicle under the action of an operating means disposed at the upper end of the fastening member so that it can be actuated by the occupant of the wheelchair.
  • the wheelchair is equipped with a seat belt for retaining the occupant of the chair in the latter, said seat belt being fixed to the fastening members.
  • Said retaining member is constituted by an elongated trough-shaped profile open upwards, embedded in the floor of the vehicle transversely to the normal running direction of the vehicle, the front longitudinal edge of said profile being extended rearwards to the height of the floor and carrying at its free end a flange facing downwards.
  • Each attachment member comprises a tube rigidly fixed to the two lower and upper longitudinal members of the frame of the chair, and a rod slidingly mounted in said tube, said rod being provided at its lower end, projecting from the lower end of said tube, with a gripping tab facing forward in the direction of travel of the wheelchair and having at its free end an edge turned upwards, and at its upper end means capable of being actuated by the occupant of the wheelchair to allow the latter to bring the gripping tab in the low position to engage this tab in the retaining profile and in a high position and lock it in this high position, the edge of the gripping tab being hooked behind the edge of the profile of detention.
  • each attachment member comprise an eccentric articulated by a substantially horizontal axis on the upper end of said rod so that its peripheral cam surface cooperates with the upper end of said tube , and an operating handle fixed to said eccentric to allow the occupant of the chair to bring the gripping tab in the low position and in the high position and lock it in the high position.
  • Each attachment member may further advantageously comprise means for immobilizing the rod relative to the tube in an elevated position in which the grip tab is at a distance above the vehicle floor and does not interfere with the normal movement of the chair. rolling.
  • the seat belt is of the type with three fixing points, the two lower points of the belt being fixed to the tubes of the fastening members, one of the columns of the back of the chair being extended above the height of the shoulders of the occupant of the chair and the third point of the belt being provided at the upper part of said column.
  • Figs. 1 and 2 illustrate a conventional wheelchair comprising a tubular chassis formed by two lateral halves 1.
  • Each chassis half 1 comprises a front upright 2 and a rear upright 3 connected together by a lower spar 4 and an upper spar 5.
  • Each half chassis 1 has at the rear a large fixed wheel 6 and at the front a small steerable wheel 7.
  • the two chassis halves 1 are interconnected by a seat 8 and, below the latter, by a system of connecting rods 9 allowing the chassis to be folded.
  • the backrest 10 is supported at the rear of the chair by two columns 11, each of which is fixed to one of the chassis halves 1.
  • the wheelchair is equipped with a seat belt to restrain the occupant of the wheelchair on the latter and a mechanism for anchoring the wheelchair to the vehicle.
  • the mechanism for anchoring the wheelchair to the vehicle comprises a member 12 fixed to each half of the chassis 1 for attaching the wheelchair to the floor 13 of the transport vehicle.
  • a retaining profile 14 is embedded in the floor 13.
  • the retaining profile 14 has the shape of a trough open upwards, arranged transversely to the direction vehicle.
  • the rear flank of the profile 14 extends obliquely backwards and upwards, up to the upper face of the floor 13.
  • the front flank of the profile 14 is extended rearwards, at the level of the upper face from the floor 13, by a horizontal edge 15 which ends in a flange 16 oriented downwards. The edge 15 is thus released and accessible both from the bottom and from the rear in the direction of travel of the vehicle.
  • the attachment member 12 comprises a rod 17 slidingly mounted inside a tube 18 fixed to the two side members 4, 5 of each half of the chassis 1. At its lower end projecting from the tube 18, the rod 17 has a tapped blind hole into which is screwed a threaded rod 19 carrying at its lower end a gripping tab 20 provided with a flange 21 facing upwards. A nut 22 makes it possible to block the threaded rod 19 relative to the rod 17.
  • the tube 18 is fixed to the half of frame 1 using two clamps 23 (see 2, 3, 4) each of which embraces one of the two side members 4, 5 of the half of frame 1.
  • the rod 17 is biased downward relative to the tube 18 by a compression spring 24 interposed between a shoulder 25 that has the rod 17 inside the tube 18 and a plug 26 fixed to the upper end of the tube 18 and crossed by the upper end of the rod 17.
  • An eccentric 27 is articulated by a transverse axis 28 on the upper end of the rod 17, above the plug 26, so that the peripheral surface of the eccentric 27 cooperates in the manner of a cam with the plug 26.
  • An operating lever 29 is fixed to the eccentric 27 so as to allow the rotation of the latter.
  • the handle 29 is fixed to the eccentric 27 so that it is substantially in the extension of the tube 18 when the axis 28 of the eccentric 27 is in its position closest to the plug 26 and is folded against the tube 18 when the axis 28 of the eccentric 27 is in its position furthest from the plug 26.
  • the handle 29 has a transverse profile in an arc of a circle adapted to the circular profile of the tube 18, so that in position folded against the tube 18, the handle 27 fits over part of your section of the tube 18.
  • a handle 30 fixed to the handle 29 facilitates the operation of the latter.
  • the gripping tabs 20 are hooked below the edge 15 of the retaining profile 14 embedded in the floor 13, the gripping tabs 20 being clamped upwards against the edge 15 of the retaining profile 14 under the action eccentrics 27 rotated so that the levers 27 are folded against the tubes 18.
  • the attachment members 12 thus block the wheelchair on the floor 13.
  • Fig. 4 shows a fastening member 12 in the inactive position, that is to say in the position in which the gripping tab 20 is raised above the surface of the floor 13 to allow the movement of the wheelchair on the floor 13.
  • the rod 17 is raised relative to the tube 18 so that the eccentric 27 is at a distance above the plug 26 and the rod 17 is immobilized in this position relative to the tube 18 , against the action of the spring 24, by the lever 29 folded against the tube 18, the free end of which, facing downwards, is engaged from the top behind a hooking tab 31 open upwards, attached to the tube 18 near its upper end.
  • the wheelchair is equipped with a three-point seat belt, of the inertia reel type.
  • the inertia reel 32 is fixed to the lower end of one of the coions 11 which is extended upwards beyond the backrest 10.
  • the strap 33 of the belt extends from the reel 32 upwards to a reference 34 mounted on the upper end of the higher column 11.
  • the other end of the strap 33 and the locking loop 35 of the belt are respectively fixed to the fastening members 12 located on the two opposite sides of the wheelchair.
  • a plate 36 (not shown in FIGS.
  • each tube 18 extends in the direction of the backrest 10 backwards from the tube 18, the said plates 36 having, in the vicinity of their free rear end, the two lower attachment points 37 for the belt, that is to say for the strap 33 and for the buckle 35.
  • the occupant of the wheelchair can, without any help, attach himself to the wheelchair, by fastening the seat belt, and anchor the wheelchair to the floor of the vehicle. It suffices that the occupant of the chair directs the latter, the levers 29 being in the position according to FIG. 4, that is to say the tabs 20 being raised above the floor 13, up to the vicinity of the location for anchoring to the floor (profile 14). It then lifts the levers 29 to release them from the lugs 31 and flaps them upwards, so that the rods 17 descend, under the effect of the springs 24 until the gripping lugs 20 bear on the floor 23. If the gripping tabs 20 were already above the retaining profile 14, they penetrate directly into the latter. Otherwise, a slight movement of the chair allows them to be engaged in this profile.
  • the tubes 18 of the fastening members 12 could be fixed to the chassis halves 1 of the chair by means other than the clamps 23, for example permanently by welding.
  • the collars 23 nevertheless have the advantage of allowing a removable fixing on armchairs of different models, the collars 23 being adjustable along the axis of the tubes 18 by means of slides 38 which can be locked by screws 39 in slides 40 integral with the tubes 18 (see fig. 3).
  • the spring 24 which urges the rod 17 downwards relative to the tube 18 is not essential, the weight of the rod 17 being generally sufficient to allow the latter to slide downwards as soon as it has been released at its upper end.
  • the seat belt for attaching the occupant to the chair may be of the two-point or three-point type, with or without a retractor, but the use of a three-point retractable belt provides better protection, facilitates the seat belt is fastened and gives the occupant more freedom of movement.
