FIELD AND BACKGROUND OF THE INVENTION The present invention relates to supporting apparatus and, more particularly, to multi- position support apparatus featuring a motorized foot support.

Hereinafter, the term "engine" refers to any device that is able to move things, including, but not limited to motor, and actuator. Basic principles and details relating to multi-position support apparatus featuring a motorized foot support needed for properly understanding the present invention are provided herein. Complete theoretical descriptions, details, explanations, examples, and applications of these and related subjects and phenomena are readily available in standard references in the fields of physics, electronics, home care devices, and elderly care. There is prior art regarding elements, systems, and methods based on, or including, multi-position wheelchairs and multi-position beds. However, none of the following indicated prior art refers to multi-position support apparatus featuring the important and novel feature of motorized foot support. U.S. Patent No. 5638563, issued to Iura Tadashi, discloses a posture change-over device, designed so that the posture of the head supporting frame when the back supporting frame is raised and pivoted can be selected from two postures; a posture where the head supporting frame is kept horizontal and a posture where the head supporting frame and the back supporting frame form one plane. Therefore, in the latter case, the bed can be used in the same manner as previous beds capable of raising the upper body, and in the former case, a user can raise his/her upper body without dropping the pillow or articles even when he/she raises his/her back. However, this device is unable to achieve a standing position and there is no user customization and no preprogrammed operation programs. European Patent No. 1180352A1, issued to Soejima Noboru et al., discloses an apparatus for moving a body, wherein a phantom axis passing from the head through the center of the legs of the body is defined as a vertical axis, a phantom axis passing through the abdomen in the longitudinal direction is defined as a longitudinal axis, and a phantom axis passing through the abdomen in the lateral direction is defined as a lateral axis, and motions around these three axes are carried out individually or in combination in order to support, twist and vertically move a body suitably for various individual somatotype and posture. However, it is unable to achieve a standing position and there is no user customization and no preprogrammed operation programs.

European Patent No. 1413281A1, issued to Horitani Masao et al., discloses a bed wherein coordinates defined by a back angle and a knee angle, a pattern that connects between a coordinate point at which each of a back bottom and a knee bottom is horizontal and a coordinate point which is a final reaching point for a back lift-up operation and at which the back bottom is lifted up by multiple points is set, and a control section moves the back bottom and the knee bottom. However, it is unable to achieve a standing position. There is also no user customization and no preprogrammed operation programs.

U.S. Patent No. 6912746, issued to Grove Christopher John, discloses a bed for accommodating heavy persons. The bed is particularly for use in hospitals, where heavy patients have to be treated. The invention provides a bed comprising a frame; a central support section mounted on the frame; two opposite end support sections, one being a head section and the other being a foot section, each mounted for pivoting movement relative to the central section; and drive means for driving the end support sections for pivoting o

movement relative to the central section; wherein the foot section has a platform which extends at an angle to the plane of the section, and the foot section can pivot to a position where the platform is substantially at ground level. In one embodiment the central section is mounted for pivoting movement about a pivot axis at or near to its edge adjacent the foot section, and further comprises drive means for driving the central support section for pivoting movement about said pivot axis. However, it is unable to achieve a standing position and there is no user customization and no preprogrammed operation programs.

U.S. Patent No. 4685159, discloses Oetiker, Hans, discloses a hospital bed which includes a bed frame consisting of a center bed frame section and of a head bed frame section and foot bed frame section pivotal relative to the center bed frame section; the bed frame is supported relative to a chassis by way of a first intermediate yoke-like frame structure providing pivotal movement in either direction of the bed frame about a single transverse axis; the first intermediate frame structure is pivotally connected with a second intermediate frame structure to provide tilting about a longitudinal axis; the second intermediate frame structure which consists of a parallelogram-linkage system provides for height adjustments of the bed frame and is so constructed and arranged as to permit the bed frame to assume a nearly vertical position with the foot bed frame section at the bottom without interference from the transverse bearer member of the chassis. However, there is no description or suggestion for a motorized foot support and there is no user customization and no preprogrammed operation programs.

U.S. Patent No. 5023967, issued to Ferrand, Robert, discloses a system providing universal support for patients, and includes an articulated platform supported by a universal joint supported by a pair of hydraulic support arms, and by a pair of lesser hydraulic arms spaced from the universal joint. The platform is comprised of multiple relatively hinged panels which are also hydraulically driven. Thus, the platform is capable of assuming a large number of configurations, including full sitting and standing positions. A patient cushion system includes multiple cushions which are individually or severally controlled through a valve and manifold system which is computer controlled for cycling cushion pressures between high and low pressures. The sides of the bed platform have restraining members which may be lowered and hinged in toward the patient to provide access to the patient. These restraining members also provide for supplemental support of such things as a canopy or tension weight. Further, a pendulum arm is attachable to the side restraint member for supporting auxiliary equipment in an upright position regardless of the orientation of the bed. A sanitary system is incorporated in the cushion system to provide cleansing and removal of bodily wastes. A restraint system, also operable by the cushion system, may be provided over the top of the patient to further restrain a patient. However, there is no description or suggestion for a motorized foot support and the disclosed embodiment is highly complicated and therefore expensive.

U.S. Patent No. 3997926, issued to England, Robert W., discloses a bed including an open supportive framework pivotably mounting an occupant support platform for movement between a horizontal and an upright position. The bed includes a drive mechanism and associated motor with controls to enable selective movement of the platform between the two positions. The drive assembly includes a lead screw operatively connecting the open framework to the platform. A nut pivotably mounted on the framework threadably receives the screw which, when turned, causes pivotal movement of the platform between the two positions. The framework is open at a foot end of the bed to enable an occupant to move freely toward or away from the support platform. The platform includes a foot rest assembly that may be selectively moved longitudinally relative to the platform between an operative and inoperative position. In the operative position, the foot rest may be utilized to receive and support the weight of the occupant, assuring that the platform cannot be pivoted past either position, that the platform cannot fall during a power outage, and that the motor will not operate unless the foot rest is in the operative position. However, this bed is unable to achieve a sitting position. Also, there is no description or suggestion for a motorized foot support and there is no user customization and no preprogrammed operation programs. U.S. Patent No. 6862762, issued to Johnson, Michael Karl, discloses the patient support apparatus which includes a base frame and a patient support assembly. The patient support assembly is pivotably mounted the base frame and is moved by a first actuator to rotate between a horizontal position and an upright position. The patient support assembly includes an upper body portion, a lower body portion and a leg portion. The upper body portion, the lower body portion and the leg portion are pivotably interconnected with a linkage frame so that they can be moved in unison by a second actuator between a supine configuration and an upright, chair shaped configuration. Thus, the patient support apparatus is adjustable between a flat, bed-shaped configuration and a seat-shaped configuration, and is also movable between a horizontal position and an upright position. However, there is no description or suggestion for a motorized foot support. U.S. Patent No. 6101646, issued to Son, Chong Eun, discloses a dual-function bed used as a chair, equipped with a patient toilet. The bed is designed to be selectively used as a chair by controlling the folding angle of it with the operation of a reduction motor. Moreover, as attached equipment, the toilet has the capabilities of cleaning itself and discharging excrement. Subsequently, this invention allows a disabled and non-ambulatory patient to relieve oneself and rest by simply operating a control unit without nurse. However, it is unable to achieve a standing position and there is no alternative method for waste disposal via an appropriate sewage system. Also, there is no user customization and no preprogrammed operation programs.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention relates to supporting apparatus and, more particularly, to multi- position support apparatus featuring a motorized foot support.

The preferred embodiments of the device of the present invention are discussed in detail below. It is to be understood that the present invention is not limited in its application by the details of the order or sequence of steps of operation or implementation of the method and/or the details of construction, arrangement, and composition of the components of the device set forth in the following description, drawings or examples. While specific steps, configurations and arrangements are discussed, it is to be understood that this is done for illustrative purposes only. A person skilled in the relevant art will recognize that other steps, embodiments, configurations and arrangements can be used without departing from the spirit and scope of the present invention.

The present invention is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology, terminology and notation employed herein are for the purpose of description and should not be regarded as limiting.

Elderly people have difficulty bending over and moving from a standing position to a sitting position, and vice versa.

People with severe knee problems also have difficulty bending their knees. As a result, the action of sitting down on a bed is difficult for them. I o

Overweight and/or obese people sometimes find it difficult to bend their knees when sitting down on a bed, and have difficulty rising up from a bed.

For simplicity, hereinbelow the terms "bed" and "multi-position bed" and "multi- position support apparatus" should have the save meaning without limiting the scope of the present invention.

The multi-position support apparatus featuring a motorized foot support of the present invention receives and lowers the user from a standing position (while both the bed and user are about vertical), into a reclining or horizontal position, optionally without having to tie and/or secure the user to the bed before the angular position change occurs. Then, when the user wants to get out of bed, the bed raises the user from lying down to standing up.

In an exemplary embodiment option of the present invention, the multi-position support apparatus features wheels which enable it to move. In an alternative exemplary embodiment option of the present invention, the wheels which enable the bed to move are motorize. In the case where the wheels which enable the bed to move are motorize, it is possible to control the movement of the bed using a control panel. The control panel allows the user to operate the different engines separately, and/or to perform complete operations such as transition from a standing position to a sitting position and vice versa, transition from a standing position to a lying position and vice versa, and transition from a sitting position to a lying position and vice versa.

Referring to FIG. 1, and FIG. 2, a main novel feature of the present invention is motorized foot support 17. It is important to have motorized foot support 17 to prevent the user from sliding as the bed shifts from a lying position to a standing position and/or when the bed shifts from a sitting position to a standing position. When the user wishes to stand up from lying down or sitting, motorized foot support 17 moves toward the head of the bed until it reaches the user's feet. Optionally, motorized foot support 17 is actuated by motor 21.

Detecting when the foot support has reached the feet of the user lying in the bed can be achieved in various novel ways. For example, a pressure sensor that measures the intensity of the resistance from the user's legs can be used. The minimal threshold of intensity measured by the sensor should be set to a high enough value to ensure that motorized foot support 17 has actually reached the user's feet, and not another object that possibly is on the bed. For example, as a safety precaution, it is important to make sure that the user is not brought to a standing position while stepping on a blanket or a pillow.

However, if the user purposely wants to be brought to a standing position while stepping on a blanket or a pillow, the pressure sensor should be configured and set to ensure that a minimal predefined amount of pressure is applied, implying that the object is pressed to the user's feet. Only when the appropriate amount of pressure is measured by the sensor, the bed begins to rise to a standing position.

In an exemplary embodiment option of the present invention, when the user wishes to shift from a lying position to a sitting position, it is possible to waive the movement of foot support. Alternatively, it is possible to enable the bed of the present invention to begin moving when the amount of pressure measured by the sensor is smaller than the predefined amount of pressure required for beginning the shifting, from a lying position to a standing position. In an exemplary embodiment option of the present invention, when the user wishes to be brought to a standing position, the multi-position support apparatus starts to change its angular position simultaneously while foot support moves toward the direction of the head of the multi-position support apparatus. Performing these two actions simultaneously saves time and does not endanger the user, as long as motorized foot support 17 reaches the user's feet in a reasonable amount of time in relation to the angular position of the multi- position support apparatus.

When the multi-position support apparatus reaches a predefined angle, motorized foot support 17 starts to come down so that the feet of the user are in close proximity to ground level when the user is brought into standing position. The object of this operation is to prevent the user from having to descend a step.

The engine of motorized foot support 17 can be positioned either underneath the multi-position support apparatus or on the side of the multi-position support apparatus.

In an exemplary embodiment option of the present invention, motorized foot support 17 may be connected to its operating engine through slots in the mattress, as illustrated in FIG. 2, FIG. 3, and FIG. 4. Alternatively, motorized foot support 17 may be connected to its operating engine using at least one arm-like extension reaching out from at least one side of the multi-position support apparatus (not shown in the figures). In that alternative embodiment it is not required that the mattress be slotted.

Referring to FIG. 2, motorized foot support 17 can move along axis 300 or along axis 301. The bed of the present invention can also be used as a chair. In an exemplary embodiment option of the present invention, the bed can be moved into a sitting position, like a TV recliner.

Referring to FIG. 3, an exemplary embodiment of the bed of the present invention features at least the following:

(a) Foot support 17 able to move towards the head of the bed when the bed is in positions other than standing, and towards the ground when the bed is in standing position (i.e. about vertical) or moves towards a standing position.

(b) Multi-position support apparatus (c) Optionally, the multi-position support apparatus being covered by a mattress. In another exemplary embodiment option the mattress comes equipped with the means for it to be attached to the bed of the present invention. Exemplary attachment means are nails, screws, hooks, and press-studs.

In an exemplary embodiment option of the present invention, the bed is equipped with a toilet bowl. Optionally, when the toilet bowl is being used, the bed shifts to a sitting position. Optionally, the toilet bowl usage is indicated by the user via a control panel (not shown in the figures).

In an exemplary embodiment option of the present invention, a foldable tray is attached to the multi-position support apparatus. The foldable try may be used as a base for placing various objects such as food, drinks, dishes, books, a remote control, a telephone, a computer, an alarm clock, etc.

The foldable tray can be folded in any way known in the art. Optionally, when the bed is changing its angular position, the foldable tray can be moved aside either manually by the user, or by an engine powered by any means known in the art, to prevent objects placed on it from falling down as the multi-position support apparatus moves.

In another exemplary embodiment option of the present invention, the bed can be raised vertically (i.e. up and down). The ability to raise the bed vertically is useful and convenient for when a user is receiving ambulatory treatments, physical examinations, getting therapy, massage, and/or any other treatments known in the art. By raising and lowering the bed, the bed's height can be adjusted to the height of the caregiver.

In another exemplary embodiment option of the present invention, the bed's armrests are not fixed to any moving parts of the bed. Thus, the user can place a blanket or any other object on the armrests before the bed is shifted from one position to another, without the object falling from the arm rests. Optionally, the bed includes a special shelf and/or tray on which various objects can be placed so that they will not fall down when the bed shifts from one position to another.

Configurations, components, operation, and implementation of the multi-position support apparatus of the present invention, are better understood with reference to the following description and accompanying drawings.

Referring to FIG. 1, an exemplary embodiment of multi-position support apparatus 10, features at least the following: back support 11, back-seat angle 13, seat 14, seat-leg angle 15, leg support 16, motorized foot support 17, and multi-position support apparatus base 19. Moreover, multi-position support apparatus 10 optionally features at least one hand support 12 and leg-foot angle 18. In an exemplary embodiment of the present invention, there is back-seat angle 13, seat-leg angle 15, and leg-foot angle 18 featuring a pivot, as know in the art. FIG. 3 illustrates another exemplary preferred embodiment of the present invention features back support 403, seat 402, seat-leg angle 401, and leg support featuring motorized foot support 17.

FIG. 4 illustrates an exemplary embodiment of the bed of the present invention in horizontal position with elements 504 and 506. In the following description of the device of the present invention, included are only main or principal details needed for sufficiently understanding proper 'enabling' utilization and implementation of the disclosed device. Accordingly, descriptions of the various required or optional minor, intermediate, and/or, sub systems, which are readily known by one of ordinary skill in the art, which are available in the relevant prior art and technical literature. Multi-position support apparatus 10 uses engines to change its angular position. For decorative or space-saving purposes, multi-position support apparatus 10 can be designed with all or most of the engines controlling its angular position concentrated beneath seat 14. The electro-mechanical structure of multi-position support apparatus 10 of the present invention may be constructed in a variety of ways known in the art, and in the novel constructions as described in the following exemplary embodiments.

The angles of multi-position support apparatus 10 are programmed so that the user returns to the standing position with maximum stability; slightly reclined. Because of its slightly reclined angle, multi-position support apparatus 10, when in a standing position, does not throw the user off-balance. It is to be understood that the meaning of "reclining" may be interpreted as "backward inclining."

FIG. 7 illustrates the angles of multi-position support apparatus 10 in standing position. Either in a standing position or when entering a standing position, angle 41 is larger than 180 degrees, in order to prevent the user from falling. Angle 40 should be smaller than 180 degrees, but not smaller than a predefined angle, which is dependent on the angular position of multi-position support apparatus 10 in its entirety.

The control system of the system of the present invention functions to prevent the user from manually reducing angle 40 beyond an angle wherein exists the possibility that the user will fall forward from the multi-position support apparatus. By using the present invention, the probability of accident is very low. Receiving the user from a standing position - and returning the user to a standing position - minimizes the probability of bed-related accidents occurring.

It is to be understood that the present invention is useful for people who cannot stand. In that case, the present invention is receiving the user from a sitting position - and returning the user to a sitting position. Angular change that is to fast can cause dizziness in elderly people. This phenomenon is known in the art as orthostatic hypotension. Optionally, the speed at which multi- position support apparatus 10 changes its angular position can be controlled and adjusted for the comfort and health condition of a user. Optionally, when the angular position changes, it is possible to stop the apparatus by using the control panel or any other controlling device

Moreover, during the transition from laying position to standing position, elderly people might suffer from orthostatic hypotension. As a result, elderly people may feel weakness, muscle tonus decrease, and even possibly faint. Muscle tonus decrease during transition to standing position may result in falling of the user from the bed. During the transition from laying position to standing position, the user is leaned against the bed until the user is standing. The danger in loosing muscle tonus is slipping down or to the side of the bed, and even falling to the front.

In an exemplary embodiment of the present invention, in order to recognize muscle tonus decrease and prevent the falling, the bed features a muscle tonus monitoring device. Muscle tonus monitoring can be achieved by various devices known in the art.

When the muscle tonus monitoring device is detecting a critical reduction in user's muscle tonus, the bed is automatically bringing the user back to a safe reclining position. In an exemplary embodiment option of the present invention, the bed prevent the falling using the following method.

Optionally, there is upbringing motorized protective barriers on the sides of the bed, thus preventing the user from slipping to the side.

There is motorized foot support 17 pushing the user's feet forward by moving on axis 301 as illustrated in FIG. 2. Thus, legs of the user are used as a lever and prevent the user from falling forward. Moreover, the lever effect helps to lean the body of the user against the bed.

Optionally, there is pushing the user's knees forward, resulting in knees bending.

Along with the feet, which are pushed forward, the user is brought to a safe position. It is important that the knees and feet are pushed forward, rather than the body of the bed is brought backward. Thus, the bed fully supports the body of the user, keeping constant contact with the user. Keeping constant contact with the user and no gap between the user's body and the bed, reduces the falling of the bed probability.

There is gradual returning of the bed to reclining position, constantly keeping contact with the body of the user.

FIG. 1 illustrates an exemplary embodiment option of multi-position support apparatus 10, capable of entering into positions of standing, sitting and reclining.

Engines are connected to the various parts of multi-position support apparatus 10.

For example, engines are connected to back support 11, seat 14, and leg support 16. In another optional embodiment (not shown in the figure), there are engines connected to the device's pivots. For example, the two engines can be connected to back-seat angle 13 and seat-legs angle 15.

The angle of back support 11, seat 14, and leg support 16, changes during operation in order to achieve maximum stability and put minimal pressure on the legs. In an exemplary embodiment option, the user enters the apparatus in a standing position, leans backwards, and upon achieving a reclined angle of 20 to 60 degrees, the apparatus begins to move the user into a sitting position. When the apparatus moves from sitting to standing the user is first brought to an inclined position of between 20 and 60 degrees, and only then is brought to a full standing position. An optional exemplary embodiment option of the present invention prevents a situation in which multi-position support apparatus 10 descends on the foot of an operator who is not the user, such as a nurse. One or more sensor is placed in or on foot support 17.

The one or more sensor detects objects and prevents foot support 17 from crushing them.

Optional sensors include, but are not limited to, infra-red sensor, electric footboard that sends a signal when it is stepped upon, micro switch, camera, or any other sensor known in the art.

Another optional exemplary embodiment of the present invention prevents a situation in which back support 11 crushes an operator who is not the user, such as a nurse. One or more sensor is placed in or on back support 11. The one or more sensor detects objects and prevents back support 11 from crushing them. Optional sensors include, but are not limited to, infra-red sensor, electric footboard that sends a signal when it is stepped upon, micro switch, camera, or any other sensor known in the art.

In order to achieve a reclining position (180 degrees), it is possible to create an indentation in the pivot area so that the pivot will fall into the indentation when the multi- position support apparatus is stretched, as required for a reclining position.

Optionally, the armrests of the multi-position support apparatus of the present invention can move up, down, and to the sides, to enhance the user's comfort. Optionally, the armrest can be detached from the multi-position support apparatus. In this case, when the multi-position support apparatus moves, the armrests are not moving along with it, to allow the user to comfortably reach for an object or shelf during changes in position.

Referring to exemplary embodiment option illustrated in FIG. 8, the use of one engine and a parallelogram-based structure enables the multi-position support apparatus to shift from a standing to a sitting position, or from a sitting to a reclining position.

Parts 80 and 90 operate a rod that can decrease or increase in length. When the rod's length grows, the device shifts to a reclining position.

Referring to optional embodiment illustrated in FIG. 9, the leg-support and back- support move nearly together and therefore one engine can be used for both. The second engine is used for changing the angle of the multi-position support apparatus.

FIG. 9 illustrates a parallelogram-based structure device with two engines. The operation of the first engine is identical to that of the parallelogram-based structure device with one engine. Operation of the second engine raises and lowers the device. 101 is an engine for shifting from a sitting to a standing position.

The apparatus is fixed to axis 103.

The purpose of engine 102 is to shift the apparatus from a sitting to a lying position. It is to be noted that in the parallelogram-based structure device, 104 and 105 are parallel and move in tandem. In a non-parallelogram-based structure device, it is sometimes possible to control each of the parts independently or almost independently.

Referring to FIG. 1, an optional exemplary embodiment of the present invention shows the states of engines 23, 24, and 25 setting the angular position of multi-position support apparatus 10. Use of three or more engines to control the angular position of multi-position support apparatus 10 enables further adjustment of the movement of multi-position support apparatus 10, for the comfort of the user.

It is to be understood that multi-position support apparatus 10 may include more than three parts where each part may feature a separate engine.

In an optional exemplary embodiment of the present invention, multi-position support apparatus 10 features different lengths and therefore caters to users of various heights. Therefore, the length of multi-position support apparatus 10 should be adjusted to the height of the user. Adjustment of multi-position support apparatus 10 to the user's height may be accomplished by controlling the lengths of leg-support 16 and back-support 11.

When multi-position support apparatus 10 shifts from the position of sitting to reclining, the user's body may slide down. This motion can cause uncomfortable friction to an unclothed body. To prevent the friction, it is possible to enable multi-position support apparatus 10 to move according to the motion of a user. For example, enabling the back of the bed to move according to the motion of a user's back. Referring to FIG. 5, back support 62 is floating over back-support frame 60. In an optional exemplary embodiment of the present invention, the floating of back support 62 over back-support frame 60 is achieved by slides 61. In an optional exemplary embodiment, one or more of the following parts may be floating parts: head support, back support, and leg support.

According to another option, the floating is achieved by using the following optional embodiments:

(a) Two or more tracks. Hereinafter, the term "track" refers to any device that enables movement along a specific direction.

(b) A spring holding the floating part in place is an exemplary solution for ensuring that the floating part does not move independently. To prevent quick movement by the spring it is possible, for example, to integrate the spring with a piston.

(c) Using a telescopic device. An exemplary telescopic device is shock absorbers such as those used in motorcycles or automobile luggage compartments (trunks). The functionality of the telescope device is to ensure that the support is not moving by itself and/or not moving independently when the user momentarily gets up.

It is to be understood that the use of a telescopic device is just an example and floating parts can be implemented with any other device known in the art, such as, but not limited to, the prior art wheelchairs disclosed in the background of the invention section of the present invention. As long as no command is given to change the angular position of multi-position support apparatus 10 and/or as long as the engine is idle, the floating part's position on the slide is fixed. This can be achieved by using a pin, step motor, electromagnet, etc. In this case, the telescopic device is not needed, as the floating part is not moving independently.

The floating device moves along at least one track. Options: a track down the middle, two tracks down the sides of the back-support, or any other equivalent implementation.

Optionally, instead of using a floating device, a device moved by an engine over a track can be used. This is made possible due to the fact that the distance the user's back should move depends on the angular position of the chair/apparatus, and therefore can be measured in advance.

The starting positions of the floating parts can be determined according to the specific user's height. In that case, the multi-position support apparatus of the present invention adjusts to different heights of users by moving the floating parts' positions according to the user's height. The taller a person is, the further apart the floating parts' starting position is in the apparatus' standing position.

Hereafter the floating parts of the exemplary multi-position support apparatus are described.

Referring to FIG. 1, parts 11 and 14 are nearest to one another in a standing position. The following example describes the movement of the parts in order to prevent uncomfortable friction when the apparatus changes its angular position. When an active control system that controls the position and movement of the floating parts is used, parts 11 and 14 move closer together as the apparatus shifts from a sitting to a reclining position.

Another option is using floating parts without active control. The floating parts are placed on a slide. When the user sits, parts 11 and 14 move away from one another. When the user lies down, parts 11 and 14 move closer together. To sum up, when shifting from a standing to a sitting position the parts should move away from each other, and when shifting from sitting to reclining the parts should move closer.

It is to be understood that the floating-parts solution as an exemplary method can be implemented on any of the users' body supporting parts, including the backseat and leg supports. Because relative movement is needed, it is sufficient that only the back-support part and/or the leg-support part be floating. In this case, it is not necessary for the seat to move, because the back-support and/or leg-support are moving.

In an optional exemplary embodiment of the multi-position support apparatus of the present invention, a feces-collecting device, referred to herein as "integrated toilet", can be integrated into multi-position support apparatus 10. The integrated toilet features significant hygienic advantages. Exemplary integrated toilets include a toilet, toilet bowl, and lavatory seat.

There are cases where there is a need to secure the user to multi-position support apparatus 10. For example, when the user is an elderly person suffering from Alzheimer's disease, dementia or amnesia.

Securing the user to the device can be done by using any means known in the art. For example, multi-position support apparatus 10 side-handles that close-in/envelop the user and hold the user in place, and/or support / stability / binding straps attached to the sides of multi-position support apparatus 10.

FIG. 6 is an illustration of armrest 30, which enables the user of the present invention to enter multi-position support apparatus 10 from a comfortable and safe direction 31.

Entering multi-position support apparatus 10 comfortably is achieved using two handles, armrests, or hand supports, featuring different lengths. On one side, there is a short handle for allowing easy entry into the device; on the other side, a long handle both supports the user and prevents the user from falling from the apparatus.

Moreover, the user can be secured at the knees while standing, to increase safety and stability.

In an optional exemplary embodiment of the present invention, it is possible to control the operation of the device of the present invention by one or more means of the following options: (a) Operating the device using a control button that enables choosing the desired program, (b) Operating the device using a controller that identifies voice commands, (c) Automatic operation of the device by means of user-identification, (d) Identifying the user may be achieved by any method known in the art. For example: by means of voice or visual aids, RFID, smart card, key, user's weight, control panel, etc.

After the device identifies the user, a personal program of a specific user is executed. Angles and velocities are examples of some of the parameters which can be saved in the personal program.

In another optional exemplary embodiment of the present invention, the device of the present invention is operated manually. The manual operating program activates each step/stage according to instructions from either the user or any other human operator.

In another optional exemplary embodiment of the present invention, the device of the present invention is operated by an automatic program that activates all stages, sequentially. In an optional exemplary embodiment of the present invention, the device is operated by one of the following, or by a combination thereof: (a) the user, (b) an operator who is not the user, (c) from any place where it is possible to control the device's operations via remote control or any other remote operating means as known in the art, or, (d) automatically, using methods known in the art.

In an optional exemplary embodiment of the present invention, prior to executing the program, the device activates a voice indicator that tells the user about the program to be executed. Only after the user confirms the voice-indicated selection does the device activate the program. The user can confirm execution of the program by any input means known in the art, such as pressing a confirmation button, or by voice-command.

An exemplary optional device of the present invention features an interface from which a variety of operations are controlled. The controller may be operated by the following exemplary means: manual, keyboard, voice-activation, computer-connected, for example via RS232 or USB, remote activation such as by telephone or wireless network, or by any other means known in the art. In an optional exemplary embodiment of the present invention, there is the ability to back up all or some of the parameters that have been user- customized. Examples of parameters that have undergone user-customization: User programs, angles, heights, and angular change velocity. Parameters customized for the user may be saved in the device or in any computer, or memory element, capable of communicating with the bed.

In an optional exemplary embodiment of the present invention, the device of the present invention features a Built in Test (BIT). The BIT system may be used for fast identification of failures. This capability enables the technician to more easily determine what action should be taken when coming to the user. This also makes it easier to provide price quotes to the user prior to responding for repairs. Optionally, the BIT results may be transferred to the technician's equipment via a phone line or wireless network, or any other know in the art communication aid. In an exemplary embodiment of the present invention, When installing the device at the user's site, the technician is able to set a combination of velocities, movement angles, and other parameters referred to herein as "operational customized parameters" of the device such that it is possible to fit the use of the device to the requirements, comfort and safety of the specific user. Optionally, the operational customized parameters are saved in a memory element for future use.
