DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

[0079] The features below to be considered optional as not all features listed below need be provided in an exemplary chair.

[0080] 1. A Chair having at least two axis (pivots) (REFERENCE 1.5 & 1.7) which connects to three partsBackrest (REFERENCE 1.1), Seat (REFERENCE 1.2) and Leg-rest (REFERENCE 1.3). Such leg-rest has a footboard connected to it at the feet side (REFERENCE 1.4). Such foot board is connected to an electric actuator allowing it to move in a linear movement toward the feet (head side) of the patient and to the opposite direction (REFERENCE 3.8).

[0081] The Axle/Pivot of the tilting (REFERENCE 1.5, 3.3, 4.4) is, when in seating position, higher than the Seating support surface (REFERENCE 1.2, 3.7). Which allows the chair to be low enough as a regular armchair. This structure allows the seating support surface, which is connected to the leg-rest and footboard, to raise while tilting, so there is enough height from the floor to achieve full tilt as in FIGS. 2 and 4.

[0082] 2. The chair has at least two electric actuators for moving the Chair (apparatus) to various positions, including Seating/Reclining position (FIG. 1), Lying position (FIG. 3) and Standing position (FIG. 2).

[0083] 3. The Actuators can be connected to a controller which can be pre-programmed to define the movement of the different parts of the chair.

[0084] 4. Examples for possible operation of the chair

[0085] a. From seating position to standing position (FIG. 7 to FIG. 8 and FIG. 9)By pressing a button on handset or the button on the vertical handle (REFERENCE 5.1), the controller gets the command to do the following processesMoves backrest Down by closing backrest actuator (REFERENCE 3.9), Move leg-rest up and footboard out, by opening leg-rest (REFERENCE 3.10) and footboard actuators (REFERENCE 3.8), move footboard in until touches the feet by closing footboard actuator (REFERENCE 3.8), and tilt by opening the tilt actuator (REFERENCE 3.10). While user is tilted the footboard carrying the user feet will move down, so when fully tilted the footboard is touching the floor or in close position (REFERENCE 2.4).

[0086] b. From Fully tilted to seating position (FIG. 9 to FIG. 10 and to FIG. 7)By pressing a button on the handset the footboard will be raised by moving footboard actuator, The chair will tilt down by closing tilt actuator. Backrest will be raised by opening backrest actuator and leg-rest will move down by closing leg-rest actuator.

[0087] All movements of any part of the chair, i.e. Backrest, Leg-rest, footboard, seat can be moved independently by moving actuator which is connected to the relevant part.

[0088] 5. The chair may have on its armrest/Handles (REFERENCE 1.6, 2.1, 3.4), vertical stick (REFERENCE 3.5) connected to at least one of the arm-rests.

[0089] 6. The chair may have handles which can be connected to the side of the backrest (REFERENCE 3.4) or the armrest (REFERENCE 1.6, 2.1). Such handles have a mechanism (REFERENCE 3.9) which is changing the angle in respect to the angle between the seat support and the backrest or the angle of the seat support in respect to the floor or a combination of the two (REFERENCE 1.6, 2.1, 3.4).

[0090] 7. Such angle change of the armrests may be done with a mechanical structure (REFERENCE 3.8) or by an electric actuator connected to the armrest and controlled by the chair main controller, having a program which define its position in respect to the other actuators position.

[0091] The angle between the handle and the backrest and seat support will change as seen in (FIGS. 1 to 4).

[0092] 8. The chair will allow the user moving to any seating position, with legs down, up, backrest up, down, to a tilting position and Trendelenburg position (FIGS. 1, 2 and 3).

[0093] 9. Such chair (apparatus) can be in a size of a chair/Arm-chair. The chair can come in different dimensions to allow smaller and bigger people.

[0094] 10. The footboard connected to the Leg-rest may move in and out for physical therapy of the user.

[0095] 11. Such footboard may have a sensor which will send a signal when the footboard is pressed by the user.

[0096] 12. Such footboard may have a scale integrated.

[0097] 13. Such footboard may have a sensor on its outer side for preventing the footboard from pressing on an object or someone, during the end of the tilting.

[0098] 14. The Chair has armrests, on which it has one or two special vertical handles (REFERENCE 2.1 & 3.5) to operate some functions of the chair by the user while having a safe grip.

[0099] The vertical handle (REFERENCE 1.6, 2.1, 3.5, 4.1) may have a control button (REFERENCE 5.1) to electrically operate the chair to move it at least to standing and lying position, but can also move the user to any seating angle position.

[0100] 15. On the arm rest there can be an additional operating button in a location (REFERENCE 5.2), which will allow the user to reach it, while in lying position or any other position in the chair, so He will always be able to reach an operating button.

[0101] 16. The chair may have a Tablet (REFERENCE 6.1) which will be connected to the operating system of the chair through [0102] Wi-Fi [0103] Infra-Red [0104] Wired [0105] Bluetooth [0106] Any other commercial connectivity possibility
