Definitions
- the invention relates to a movement device for mounting in a support device and a support device which entails that at least one part of the device actively moves in a continuously predetermined fashion.
- the pattern of the movement occurs independently of the movement of the user.
- the movements entail that the muscles of the user are continuously activated changing the muscle strain of the user, which again entails that the user does not get tired and sore as quickly as usually.
- the invention further relates to a support device, such as a bed or a chair comprising such a movement device.
- some chairs have incorporated adjustment means, where the user can adjust the seat and back portions of the chair using the adjustment means.
- the movement/weight of the user can also induce the adjustment means to expand or contract whereby the back and/or the seat of the chair moves accordingly.
- Beds are also known to have movement systems such as spring systems and elevation systems, where the movements of the systems are induced by the user, either by the movement/weight of the user that induces the springs to contract or by the user adjusting the elevation of the bed by influencing the adjustment means.
- the object of the present invention is to solve the above mentioned problems.
- the tilting movements bering along a change in muscle activity of the user sitting on the sitting device or lying on the lying device which increases the blood flow in the body and are therefore beneficial to people with tendency to sit or lie still for long hours. Due to the slightly tilting automatic movements, the user does not novice - or only vaguely notices - these active patterns of movements.
- the tilting of said at least one support surface occurs independently of the movement of the user.
- the tilting is a continuous movement Induced by the actuating means, and not under influence of the user.
- the support surface can be any surface that supports the user.
- the actuating means can e.g. be hydraulic/pneumatic, electrically or motor driven, but any suitable actuating means can of course be used to tilt the support surface.
- said movement device comprises actuating means for tilting two support surfaces of said support device, said tilting of said two support surfaces being a cyclic movement, the cycle time of said two support surfaces being different from each other.
- the cycle time of the one support surface is twice the cycle time of the second support surface.
- said movement device comprises actuating means for tilting the lumbar back part of said support device.
- said movement device comprises actuating means for tilting the seat part of said support device, said tilting being a sideways tilting.
- the active and automatic movement of a support device being a lying device is advantageous in that the lying device can be especially beneficial for bedbound people who have to lie still in the bed for a long time.
- the active and automatic movement brings along a significant change in muscle activity, entailing less muscle fatigue of the user, which increases the blood flow in the body and also induces greater comfort by entalling a reorganization of the strain and burden in the body of the person. Therefore the movement device is obvious to implement into hospital and nursing beds.
- All the figures show an office chair. However, it is important to stress that the movement device of the present invention can be mounted on every kind of sitting device such as sofas, car seats, office chairs and easy chairs, just to mention a few, and also In lying devices, such as sofas or divas.
- the office chair on the figures only illustrates one embodiment of a device wherein the movement device can be implemented.
- Figure 1a and b show the concept of the invention.
- a movement device according to the invention is implemented in a chair.
- Figure 1a shows that the movement device entails that the back portion of the chair moves constantly in a predetermined fashion (101). The back portion is in this embodiment tilting backwards and forwards but it could be any other pattern of movement such as eg. sideways movements.
- Figure 1b shows a chair where the movement device entails that the seat of the chair is moving in a predetermined fashion (103). In this embodiment the seat is tilting sideways, but again it could be any other pattern of movement such as tilting forwards and backwards.
- the movement device entails that either or both the back part or/and the seat part of the chair is moving.
- any other support surfaces of a support device could also be controlled by the movement device.
- the pattern of the movement occurs independently of the movement of the user.
- the automatic, active movements are very modest and weak, so that the user does not notice - or only vaguely notices - these active patterns of movements.
- the movements entail that the muscles of the user are continuously activated changing the muscle strain of the user, which entails that the user does not get tired and sore as quickly as usually.
- Figure 2 shows a chair 201 with a seat portion 203 and a back portion.
- the back portion is divided Into two parts; a lumbar back part 205 and an upper back part 207.
- a lumbar back part 205 changes the angle in respect to the seat position 203 when the back actively moves in predetermined movements caused by the movement device, whereas the upper back part 207 continues to be positioned in a predetermined angle in respect to the seat position 203 - and therefore also in respect to a vertical upright position of the back part.
- the angle between the upper back part 207 and the seat portion 203 is In one embodiment 10 degrees.
- a four-link mechanism (a parallelogram) 211 connects the seat and the upper part of the back.
- the split 209 between the upper part and the lumbar part of the back is in one embodiment positioned 20 cm above the height of the upper side of the seat.
- the lumbar back portion actively moves in a tilting mode backwards and forwards.
- the actual amplitude should be chosen considering that upholstery of the support device might absorb a part of the movement.
- the actuating means of the movement device (not shown on the figure) can be hydraulic/pneumatic, actuator or motor driven, but any suitable actuating means can of course be used to tilt the support surface.
- Figure 3 shows a chair 301 with a seat portion 303 and a back portion.
- the seat actively moves in predetermined movements, caused by the movement device.
- the seat is moving from side to side.
- This constant sideway seat tilt movement 311, performed by the movement device changes the condition of the supporting structure In the seat, which entails a reorganization of the strain and burden in the body of the person sitting on the chair. This induces greater comfort and less muscle fatigue.
- the combined movements mimic "figure eight" movements.
- the cycle time of the seat portion is twice the cycle time of the lumbar portion to counteract repeated symmetry that can be negative for the user.
- the cyclic figure eight movements bring along a significant change in muscle activity of the user which increases the blood flow in the body. This is especially beneficial to people with tendency to sit still for long hours.
- the chair can, besides these constant, predetermined active movements implemented by the movement device, also have the possibility of voluntary movements, these movements being independent of the automatic movements.
- These voluntary movements e.g. tilting the back backwards by pressing the weight back or tilting the seat forward by pressing the legs down towards the ground, are linked to the pattern of the movements of the user and therefore dependent on the movements of the user sitting on the chair.
- the chair can also be adjusted by the user. These adjustments include adjustment of the stiffness of the spring, adjustment of the height of the seat position and adjustment of the depth of the seat. All of the adjustments, both regarding the user adjustable movements and the active and automatic movements performed by the movement device, can be linked to person identification, e.g. via RFID tags or via a personal ID card with the user specific adjustment loaded thereon, so that the chair automatically adjusts these features after identification of the user.
- the chair can be regulated and adjusted before the first time the chair is used.
- This user specific pre-adjustment of the chair itself and the movement device can be conducted via a software program that takes body characteristics, height, weight and age of the user in consideration. The chosen adjustment is loaded to a personal ID card.
- an occupational therapy adjustment can also take place, where an occupational therapist in cooperation with the user finds the correct adjustments of the chair.
- These adjustments can e.g. via wireless communication be coded on a personal ID card so that the chair automatically adjusts to the user after identification of the user via e.g. loading the personal ID card into a computer.

Description
- The invention relates to a movement device for mounting in a support device and a support device which entails that at least one part of the device actively moves in a continuously predetermined fashion. The pattern of the movement occurs independently of the movement of the user. The movements entail that the muscles of the user are continuously activated changing the muscle strain of the user, which again entails that the user does not get tired and sore as quickly as usually. The invention further relates to a support device, such as a bed or a chair comprising such a movement device.
- Chairs, such as office chairs, car seats, sofas etc., where both seat and back part can move in various dimensions, have been known for a long time. The intention of such chairs is to increase the wellbeing and to reduce tiredness of the user sitting on the chair. In some chairs it is the movement/weight of the user that induces the springs to contract whereby the back and/or the seat of the chair moves accordingly. If the user leans back, then the back part of the chair gives in and moves according to the movement of the user to a certain degree. Also, if the user tips to one side of the seat so that most of the weight is positioned on one side of the seat, then the seat part gives in and moves according to the users movement to a certain degree.
- Also, some chairs have incorporated adjustment means, where the user can adjust the seat and back portions of the chair using the adjustment means. The movement/weight of the user can also induce the adjustment means to expand or contract whereby the back and/or the seat of the chair moves accordingly.
- A chair with a movement device described in
WO 2010/043955A3 . - Beds are also known to have movement systems such as spring systems and elevation systems, where the movements of the systems are induced by the user, either by the movement/weight of the user that induces the springs to contract or by the user adjusting the elevation of the bed by influencing the adjustment means.
- Drawbacks of solutions as mentioned above are that the movements, besides the adjustment, are induced by the user. The user has to activate the muscles to induce movement of the chair or bed. However, some users sit or lay very still while for example working in front of a computer screen, watching TV or driving the car. If you sit or lay very still for a long time, you will eventually get tired and sore.
- The object of the present invention is to solve the above mentioned problems.
- This is obtained by a movement device for mounting in a support device according to claim 1.
- The tilting movements bering along a change in muscle activity of the user sitting on the sitting device or lying on the lying device which increases the blood flow in the body and are therefore beneficial to people with tendency to sit or lie still for long hours. Due to the slightly tilting automatic movements, the user does not novice - or only vaguely notices - these active patterns of movements.
- The tilting of said at least one support surface occurs independently of the movement of the user. The tilting is a continuous movement Induced by the actuating means, and not under influence of the user.
- The support surface can be any surface that supports the user.
- The actuating means can e.g. be hydraulic/pneumatic, electrically or motor driven, but any suitable actuating means can of course be used to tilt the support surface.
- In an embodiment said movement device comprises actuating means for tilting two support surfaces of said support device, said tilting of said two support surfaces being a cyclic movement, the cycle time of said two support surfaces being different from each other.
- In an embodiment the cycle time of the one support surface is twice the cycle time of the second support surface.
- In an embodiment said movement device comprises actuating means for tilting the lumbar back part of said support device.
- In an embodiment said movement device comprises actuating means for tilting the seat part of said support device, said tilting being a sideways tilting.
- The active and automatic movement of a support device being a lying device is advantageous in that the lying device can be especially beneficial for bedbound people who have to lie still in the bed for a long time. The active and automatic movement brings along a significant change in muscle activity, entailing less muscle fatigue of the user, which increases the blood flow in the body and also induces greater comfort by entalling a reorganization of the strain and burden in the body of the person. Therefore the movement device is obvious to implement into hospital and nursing beds.

Figure 1a and b show the concept of the invention. A movement device according to the invention is implemented in a chair.Figure 1a shows that the movement device entails that the back portion of the chair moves constantly in a predetermined fashion (101). The back portion is in this embodiment tilting backwards and forwards but it could be any other pattern of movement such as eg. sideways movements.Figure 1b shows a chair where the movement device entails that the seat of the chair is moving in a predetermined fashion (103). In this embodiment the seat is tilting sideways, but again it could be any other pattern of movement such as tilting forwards and backwards. In these figures the movement device entails that either or both the back part or/and the seat part of the chair is moving. However, it is not necessarily the back part and the seat part that are controlled, any other support surfaces of a support device could also be controlled by the movement device. The pattern of the movement occurs independently of the movement of the user. The automatic, active movements are very modest and weak, so that the user does not notice - or only vaguely notices - these active patterns of movements. The movements entail that the muscles of the user are continuously activated changing the muscle strain of the user, which entails that the user does not get tired and sore as quickly as usually. -
Figure 2 shows achair 201 with aseat portion 203 and a back portion. The back portion is divided Into two parts; alumbar back part 205 and anupper back part 207. Here, it is only thelumber back part 205 that changes the angle in respect to theseat position 203 when the back actively moves in predetermined movements caused by the movement device, whereas theupper back part 207 continues to be positioned in a predetermined angle in respect to the seat position 203 - and therefore also in respect to a vertical upright position of the back part. The angle between theupper back part 207 and theseat portion 203 is In one embodiment 10 degrees. In order for the angle between the upper back part and the seat portion to be constant, a four-link mechanism (a parallelogram) 211 connects the seat and the upper part of the back. Thesplit 209 between the upper part and the lumbar part of the back is in one embodiment positioned 20 cm above the height of the upper side of the seat. In one embodiment the lumbar back portion actively moves in a tilting mode backwards and forwards. In an embodiment the actual amplitude should be chosen considering that upholstery of the support device might absorb a part of the movement. The actuating means of the movement device (not shown on the figure) can be hydraulic/pneumatic, actuator or motor driven, but any suitable actuating means can of course be used to tilt the support surface. -
Figure 3 shows achair 301 with aseat portion 303 and a back portion. The seat actively moves in predetermined movements, caused by the movement device. In one embodiment the seat is moving from side to side. This constant sidewayseat tilt movement 311, performed by the movement device, changes the condition of the supporting structure In the seat, which entails a reorganization of the strain and burden in the body of the person sitting on the chair. This induces greater comfort and less muscle fatigue. - In one embodiment, where both the lumbar back portion and the seat move, the combined movements mimic "figure eight" movements. In one embodiment the cycle time of the seat portion is twice the cycle time of the lumbar portion to counteract repeated symmetry that can be negative for the user. The cyclic figure eight movements bring along a significant change in muscle activity of the user which increases the blood flow in the body. This is especially beneficial to people with tendency to sit still for long hours.
- The chair can, besides these constant, predetermined active movements implemented by the movement device, also have the possibility of voluntary movements, these movements being independent of the automatic movements. These voluntary movements, e.g. tilting the back backwards by pressing the weight back or tilting the seat forward by pressing the legs down towards the ground, are linked to the pattern of the movements of the user and therefore dependent on the movements of the user sitting on the chair.
- The chair can also be adjusted by the user. These adjustments include adjustment of the stiffness of the spring, adjustment of the height of the seat position and adjustment of the depth of the seat. All of the adjustments, both regarding the user adjustable movements and the active and automatic movements performed by the movement device, can be linked to person identification, e.g. via RFID tags or via a personal ID card with the user specific adjustment loaded thereon, so that the chair automatically adjusts these features after identification of the user.
- The chair can be regulated and adjusted before the first time the chair is used. This user specific pre-adjustment of the chair itself and the movement device can be conducted via a software program that takes body characteristics, height, weight and age of the user in consideration. The chosen adjustment is loaded to a personal ID card. In connection with or instead of the pre-adjustment conducted by a software program, an occupational therapy adjustment can also take place, where an occupational therapist in cooperation with the user finds the correct adjustments of the chair. These adjustments can e.g. via wireless communication be coded on a personal ID card so that the chair automatically adjusts to the user after identification of the user via e.g. loading the personal ID card into a computer. Instead, the user identification could be performed via RFID technology where the user identifies him- or herself.
