    Description of the Related Art
    Particularly in relation to elder care, care of people with physical or mental handicaps or disabilities, persons may have such reduced mobility that they are not able to go to the toilet or take a shower by themselves.
    From the international patent application WO 99/60977 it is therefore known to place the person in a chair provided with a hole in the seat, so that the person may go to the toilet through this hole. However, in relation to persons that are more or less paralysed or are more or less self-immobile it is also a difficult task to remove the persons trousers and/or undergarment both in relation to the toilet function and in relation to bathing the person or simply dressing and undressing the person. From WO 99/60977 it is therefore known to form the chair with adjustable back and leg rest so that the persons seat and thigh area are lifted of the chair so that the persons trousers and/or undergarment may be pulled down. However, this chair requires substantial mobility of the user or substantial lifting of an assisting nurse or other.
    An object of the invention is therefore to provide for advantageous technique for use in relation with dressing and undressing a weak or handicapped person.

    Detailed description of the invention
    Fig. 1 illustrates a toilet chair 1 in raised position, as seen from the side, and fig. 2 illustrates a toilet chair 1 in raised position, as seen in perspective.
    In this embodiment, the toilet chair 1 comprises an underframe 10 provided with height adjustment means arranged to enable that the height of the chair 1 may be adjusted - i.e. the seats 5 distance from the floor may be adjusted through a multijoint mechanism and an electrical powered actuator (not shown). However, in another embodiment the chair 1 could be arranged to be height adjusted in other ways, such as by means of spring, air cylinders or other, the height adjustment could be manual or the chair 1 could be arranged with the seat 5 in a fixed height.
    In this embodiment, the chair 1 is also provided with wheels 15 enabling that the chair 1 may be pushed around, e.g. to move the user into a bathroom or the like. However, in another embodiment at least some of the wheels 15 could be driven so that the chair 1 would be self-propelled and so that the user may use the chair as a transport vehicle.
    In another embodiment, the chair 1 could be formed without wheels 15 so that the position of the chair 1 would be more or less fixed.
    In this embodiment, the toilet chair 1 comprises a chair back 2, which in this embodiment is formed by a head part 3 and a bottom part 4. In this embodiment, the head part 3 is formed by two individual parts but in another embodiment the head part 3 could be formed as one single part or as three or more individual parts all arranged at the head area of a chair back 2..
    In another embodiment, the back 2 could comprise more parts than just the head part 3 and the bottom part 4.
    DK 2018 70029 A1
    In this embodiment, the bottom part 4 is formed as a single part but in another embodiment the bottom part 4 could be formed by two or more individual parts all arranged at the lower back area of a chair back 2.
    In this embodiment, the chair 1 is also provided with a seat 5 which in this case comprises a front part 6 - arranged at the thigh area of a chair user - and a rear part 8 - arranged at the buttocks area of a chair user.
    In this embodiment both the front part 6 and the and the rear part 5 are each formed as a single part but in another embodiment the front part 6 and/or the rear part 5 could be formed by two or more individual parts.
    In this embodiment, the seat 5 is provided with a toilet opening 7 enabling free access through the seat 5, so that a user of the chair 1 may go to the toilet into a bedpan, a toilet, a potty or similar located under or in the toilet opening 7 while sitting in the chair 1.
    In this embodiment, the toilet opening 7 extends across both the front part 6 and the and the rear part 5 but in another embodiment the toilet opening 7 could be formed in only the front part 6 or only in the rear part 5.
    Since the bottom part 4 is defined as being the lower part of the back 2 and since the rear part 8 is defined at being the part of the seat 5 being furthest to the rear (i.e. nearest to the chair back 2) the bottom part 4 and the rear part 8 are therefore arranged next to each other in this embodiment, with nothing but a crack between the two parts 5, 6. However, in another a narrow part - such as a fillet, a bridging part, a moulding, a bar or other -- may be arranged between the two parts 5, 6 e.g. to increase comfort, to reduce crush hazard or other.
    DK 2018 70029 A1
    In this embodiment the chair back 2, the seat 5, the ieg rest 10 and substantially all other parts of the chair are formed from a non-hygroscopic material such as a plastic material -- e.g. polyurethane foam, nylon, melamine or other -, a metal such as aluminum, stainless steel, coated steel or other, natural or artificial rubber materials or another material that is substantially structurally stable and does substantially not absorb water or disintegrate when being subject to water. Also in this embodiment actuators, joints, wirings and other are formed substantially waterproof so that the entire chair 1 may be washed without particular considerations and so that a person can be bathed while sitting in the chair 1.
    In this embodiment, the chair 1 is shown without armrests but in a preferred embodiment both sides would be provided with an armrest both to increase comfort for the user - in that the user will be able to rest arms on the armrests - but also to increase the safety of the chair 1 in that the armrests will reduce the risk of a weak or immobile person falling out of the chair 1. In a preferred embodiment, the position and/or angle of the armrests will follow' or at least somehow be linked to the angle and/or position of the chair back 2.
    Fig. 3 illustrates a toilet chair 1 in lowered position, as seen from the side.
    In this embodiment, the toilet chair 1 comprises back angle adjustment means 9 for adjusting the back angle BA of the back 2 in relation to the seat 5 so that the back 2 may be adjusted from a more or less upright position as disclosed in fig. 1 to a leaned back position as disclosed in fig. 3.
    In this embodiment, the back angle adjustment means 9 enables that the back angle BA between the back 2 and the seat 5 may be adjusted between 100 and 140 degrees but in another embodiment the back angle BA could be adjustable between 80 and 180 degrees or between 90 and 160 degrees or any combination thereof.
    DK 2018 70029 A1
    Also in this embodiment, the toilet chair I comprises leg rest angle adjustment means 11 for adjusting the leg rest angle LA of the leg rest 10 in relation to the seat 5 so that the leg rest 10 may be adjusted from a more vertical position as disclosed in fig. 1 to the raised position disclosed in fig. 3.
    In this embodiment, the leg rest angle adjustment means 11 enables that the leg rest angle LA between the leg rest 10 and the seat 5 may be adjusted between 80 and 30 degrees but in another embodiment the leg rest angle LA could be adjustable between 120 and 0 degrees or between 90 and 15 degrees or any combination thereof.
    In this embodiment, the toilet chair 1 is also provided with seat angle adjustment means (not shown) for adjusting the seat angle SA of the seat 5 in relation to the underlying ground so that the seat 5 may be adjusted from a more or less horizontal position disclosed in fig. 1 to the slightly tilted position disclosed in fig. 3.
    In this embodiment the back angle BA, leg rest angle LA and the seat angle SA can be individually adjusted but in another embodiment two or more of these could be mechanically coupled, so that if e.g. the back 2 is moved backwards the leg rest 10 is automatically simultaneously raised.
    In this embodiment, the back angle adjustment means 9 and the leg rest angle adjustment means 11 are enabled through joints by which the leg rest 10 and the back 2 may tilt in relation to the seat 5 and in this embodiment the back angle BA, leg rest angle LA and the seat angle SA can be individually adjusted by means of individual actuators (not shown) but in another embodiment the back angle BA, leg rest angle LA and/or the seat angle SA could be coupled and adjusted by means of the same actuator and/ one or more could also or instead be manually operated.
    Fig. 4 illustrates a toilet chair 1 with a rear part 8 raised, as seen from the side.
    DK 2018 70029 A1
    In this embodiment, the rear part 8 is arranged to be displaceable upwards in a direction towards the front of the chair 1 independently of the front part 6 so that the upper part of the buttocks - the part neighbouring the lumbar area - of a person occupying the chair 1 is directly lifted. Furthermore, in this way the lumbar area of this person is also lifted and a helper may pull the trousers and/or undergarment of this dressed person down towards the rear part 8. After this the bottom part 4 is raised and the rear part 8 is lowered as disclosed in fig. 5 so that the buttocks area of the person is lifted free of at least most of the seat 5 so that the trousers and/or undergarment may be pulled further down towards the knees of the person. After the trousers and/or undergarment are pulled past the rear part 8, the rear part 8 could be raised again to enable that the trousers and/or undergarment may be pulled further down. With trousers and/or undergarment in this pulled down position the person may go to the toilet through the toilet opening 7 or the helper may remove the trousers and/or undergarment completely e.g. before a shower or in relation to changing clothes.
    When the trousers and/or undergarment needs to come back up around the waist of the person in the chair 1, the process is more or less reversed in that first the rear part 8 and the bottom part 4 (or only the rear part 8 and then the bottom part 4) is raised so that the trousers and/or undergarment may be pulled up to the rear part 8 after which the rear part 8 is lowered and the trousers and/or undergarment are pulled up to the bottom part 4. The rear part 8 is then lifted again and the bottom part 4 is lowered so that the trousers and/or undergarment may be pulled all the way back up around the waist of the person before the bottom part 4 is lowered and the leg rest 10 and back 2 is e.g. returned to the position disclosed in fig. 1 and/or the person is lifted back into bed.
    In this embodiment, the displacing of the rear part 8 is enabled through seat mechanical actuation means 17 which in this case comprises rear part actuator 19 and
    DK 2018 70029 A1 linear guiding means 13 arranged to guide the rear part 8 linearly up and down in relation to the front part 6. However, in another embodiment the seat mechanical actuation means 17 could be formed to displace in a tilting manner and/or be enabled differently e.g. through a motor, through manually operated displacing means or otherwise.
    In this embodiment, the rear part 8 is arranged to extend 8 centimetres up from the seat 5 when in upper position, but in another embodiment the stroke of the rear part could be 6, 4 or even fewer centimetres or the stroke could be 10, 12 or even more. Or the stroke could be adjustable.
    Fig. 5 illustrates a toilet chair 1 with a bottom part 4 raised, as seen from the side.
    In this embodiment, the bottom part 4 is arranged to be displaceable outwards in a direction towards the front of the chair 1 independently of the head part 3 so that the lumbar area of a person sitting in the chair may be lifted so that at least some of the buttocks area of the person is lifted free of the seat 5.
    In this embodiment, the displacing of the bottom part 4 is enabled through back mechanical actuation means 16 which in this case comprises a tilt joint 12 - around which the bottom part 4 is arranged to tilt in relation to the head part 3 -- and a bottom part actuator 18. However, in another embodiment the back mechanical actuation means 16 could be formed to displace linearly and/or be enabled differently e.g. through a motor, through manually operated displacing means or otherwise.
    In this embodiment, all actuators on the chair are electrically powered and the chair would therefore also be provided with an electrical power source such as a battery'. However, in another embodiment the motion of the chair and chair parts could be driven differently, e.g. through pneumatics, hydraulics, motors or other.
    DK 2018 70029 A1
    In this embodiment, the bottom edge of the bottom part. 4 is arranged to be raised around 8 centimetres in upper position, but in another embodiment the stroke of the bottom part 4 could be 6, 4 or even fewer centimetres or the stroke could be 10, 12 or even more. Or the stroke could be adjustable.
    The invention has been exemplified above with reference to specific examples of chair designs, angle adjustment means 9, 11, tilt joints 12 and other. However, it should be understood that the invention is not limited to the particular examples described above but may be designed and altered in a multitude of varieties within 10 the scope of the invention as specified in the claims.
