ABSTRACT OF THE DISCLOSURE
A wheel chair or the like comprises a frame having rollers, wheels or the like; a seat section including arm, foot, and back rests, mounted on the frame; and a drive mounted on the frame for the travelling movement of the wheel chair.
The seat section along with the arm, foot, and back rests is rotatably mounted on the frame for tilting from a normal seat-ing position upwardly and backwardly relative to the frame, and there is provided a lifting device, operable by the drive, for tilting the seat section into a desired position.

Description
~L4~ 4t~
This inVention relates to a wheel chair or the like.
For more or less seriously physically handicapped patients, there have been developed certain provisions on wheel chairs which enable the patients to transport them-selves without the help of others.
This is more difficult if the patient is very seriously disabled, for example, owing to congenital or acquired damage to the spine or the central nervous system.
In addition to having difficulties in walking, such patients are in need of supports at various places, and further require adaptation of their sitting posture to different activities~
Wheel chairs driven by a motor are well-known. In those cases, however, they have been designed particularly to meet a patient's difficulties in walking, and it is contemplated that practically all other functions can still be performed by the patient.
It is an object of the present invention to make a wheel chair of the last-mentioned kind more universally applicable, that is to say, to render it suitable for use by patients having not only a walking handicap, but also other serious con~itions involving the loss of normal muscular functions, with particular attention to the patient's sitting posture, adapted to particular activities.
The present invention aims at providing a wheel chair or the like, which is a help~ul aid even in cases in which the patient is able virtually exclusively to move the fingers.

The present invention aims at providing a wheel chair or the like, which is a help~ul aid even in cases in which the patient is able virtually exclusively to move the fingers.
- 2 -`~
According to the invention, then, there is provided a wheelchair or the like of the type comprising a frame having rollers, wheels or like means, a seat section including arm, foot and back rests, mounted on the frame, and drive means mounted on the frame for the travelling movement of the wheelchair characterized in that the seat section along with the arm, foot and back rests is rotatably mounted about horizontal -shaft means affixed to the frame for tilting from a normal seating position upwardly and backwardly relative to the frame; there are provided lifting means, operable by the drive means and responsive to control m~ans for tilting the seat section into a desired position, and the control means are mounted on the seat section in the vicinity of the arm rests for rotating with the seat section within reach of a user's hand.
Accordingly, in addition to causing the wheelchair to move, to stop and to perform other functions connected with the transportation of a patient, the patient i5 capable of adjusting the seat section to any desired tilted position, using the drive means provided in the frame.
The lifting means for causing the seat section to tilt relatively to the frame can take various forms. An effective solution is a lifting device disposed between the frame and the seat section, and operable via an operating panel.
A mechanical, pneumatic, or hydraulic jack has been found to be very suitable for the purpose.
Further features will become apparent from the following description, read with reference to the accompanying drawing, which, highly diagrammatically, illustrates a side view of a preferred embodiment of the wheelchair constructed according to the present invention.
Referring to the drawlng, there is shown a wheel chair having a ~rame 1, preferably made of ligh-t and strong tubing. The wheel chair has two large rear wheels 2 provided with pneumatic tyres and two small front wheels or rollers 3, which can act as steering wheels.
Mounted in frame 1 is a drive unit 4, comprising, for example, an electric motor, a battery, conduits, switches and the like, for enabling certain functions.
Mounted on frame 1 is further a seat section 5, equipped with arm rests 6, foot rests 7, and a back rest 8.
This seat section subassembly is mounted for tilting movement relative to frame 1 about a shaft 9. In order that seat section 5 may be put into any desired position, a lifting device 10 is provided between seat section 5 and frame 1. This lifting device may be a ~ack operable mechanically, pneumatically or hydraulically. The actuating command can be given from an operating panel 11, which is conveniently situated within easy reach of the patient's hand. The lowest position of the seat section is shown dotted in the drawing.
Any other position, for example as shown in fully drawn lines, is obtained by sending, via the operating panel, a given actuating pulse to the commanding mechanism.
In the embodiment shown, the wheel chair can be displaced by electric means, and the same source of voltage is here used to provide the power to tilt the seat section.
For heavily handicapped patients, the tiltability of the seat section alone is not sufficient to meet requirements.
Therefore the wheel chair according to the invention has still 4~5 other facilities.
- The foot rests, for example, are rotatable and slidable relatively to the frame portion 13 at 11 and 12.
The angular position of back rest 8 relative to the seat 5 is adjustable through a mechanism comprising a strip 15 wlth holes therein and a peg plate 14.
The back rests has a cushion 16 with adjustable lumbar rests, one of which is shown at 17. An adjustable head rest, of known construction, is shown at 18. For completeness' : 10 sake the back rest is provided with handlesl one of which is shown at 19. This provision is necessary to provide for the case when the automatic traveI actuating system fails or possibly is absent.
.
According to the invention, then, there is provided a wheelchair or the like of the type comprising a frame having rollers, wheels or like means, a seat section including arm, foot and back rests, mounted on the frame, and drive means mounted on the frame for the travelling movement of the wheelchair characterized in that the seat section along with the arm, foot and back rests is rotatably mounted about horizontal -shaft means affixed to the frame for tilting from a normal seating position upwardly and backwardly relative to the frame; there are provided lifting means, operable by the drive means and responsive to control m~ans for tilting the seat section into a desired position, and the control means are mounted on the seat section in the vicinity of the arm rests for rotating with the seat section within reach of a user's hand.
