Reclining armchair with lifting seat and extending footrest
An armchair comprising a seat chassis supported on a support chassis by a pair of support columns, a chair back structure pivotally attached to a rear end of the seat chassis and to the support chassis, and a leg support structure pivotally attached to a front end of the seat chassis and connected to a beam, wherein the beam is attached the chair back structure. A first actuating device is mounted to the chair back, where a protracting end of the first actuating device is connected to the seat chassis. The armchair further comprises a second actuating device mounted to the support chassis, a footrest connected to a protracting end of the second actuating device, a third actuating device attached to the seat chassis, and a seating structure connected to a protracting end of the third actuating device and mounted above the seat chassis, wherein the seating structure includes an operative position projecting upwards and forwards by the third actuating device at a tilting angle from the seat chassis.
1 . An armchair comprising:
a seat chassis supported on a support chassis by one or more support columns;
a leg support structure pivotally attached to a front end of the seat chassis;
a first actuating device attached to the seat chassis; and
a seating structure connected to a protracting end of the first actuating device and mounted above the seat chassis, wherein the seating structure includes an operative position projecting upwards and forwards by the first actuating device at a tilting angle from the seat chassis to assist a user to get up from the armchair and a reclining position of the seating structure that reclines the seat chassis downwards and backwards by the first actuating device, wherein the reclining position further extends a footrest from a recessed location under the seat chassis, wherein the footrest further locks in place at a specific position to secure a user in the armchair.
2 . The armchair of claim 1 , wherein the seating structure in the operative position is at a tilted angle with respect to the seat chassis of up to 5 degrees.
3 . The armchair of claim 1 , wherein the seating structure in the operative position is projected upwards by up to 12 cm from the seat chassis.
4 . The armchair of claim 1 , further comprising a sensor embedded in the seating structure to react to a user's pressure or weight on the seating structure and activate the first actuating device to retract automatically.
5 . The armchair of claim 4 , wherein the sensor embedded in the seating structure is configurable to detect that no weight is on the seating structure for a period of time and to thereafter activate the first actuating device to automatically return the seating structure to a sitting position.
6 . The armchair of claim 1 , further comprising a chair back structure pivotally attached to a rear end of the seat chassis and to the support chassis.
7 . The armchair of claim 6 , further comprising a slider connected to the chair back structure.
8 . The armchair of claim 7 , further comprising a recliner actuator mounted to the chair back structure and connected to the seat chassis, the recliner actuator configured to bring the armchair to the reclining position.
9 . The armchair of claim 8 , wherein the slider comprises a wheel for allowing the slider to roll within a slot.
10 . The armchair of claim 9 , wherein the recliner actuator causes the slider to slide upwards in the slot and allows the seat chassis to pivot on the one or more support columns.
11 . The armchair of claim 1 , wherein the footrest is connected to a protracting end of a second actuating device mounted to the support chassis.
12 . The armchair of claim 11 , wherein the footrest is configured to lock in place at a specific position that helps secure a user from sliding down in the armchair.
13 . The armchair of claim 12 , wherein the footrest comprises a lip or friction surface to keep the user's feet on the footrest.
14 . The armchair of claim 11 , wherein the footrest is configured to extend out from the armchair to a plurality of lengths.
15 . The armchair of claim 14 , wherein the footrest comprises a sensor to detect the touching of feet on the footrest, and wherein the footrest is configured to stop extending automatically when the sensor detects the feet touching.
16 . An armchair comprising:
a seat chassis supported on a support chassis by one or more support columns;
a leg support structure pivotally attached to a front end of the seat chassis;
a first actuating device attached to the seat chassis;
a seating structure connected to a protracting end of the first actuating device and mounted above the seat chassis, wherein the seating structure includes an operative position projecting upwards and forwards by the first actuating device at a tilting angle from the seat chassis to assist a user to get up from the armchair; and
a sensor embedded in the seating structure to react to a user's pressure or weight on the seating structure and activate the first actuating device to retract automatically.
17 . The armchair of claim 16 , further including a reclining position of the seating structure that reclines the seat chassis downwards and backwards by the first actuating device, wherein the reclining position further extends a footrest from a recessed location under the seat chassis, wherein the footrest further locks in place at a specific position to secure a user in the armchair.
18 . The armchair of claim 16 , wherein the seating structure in the operative position is at a tilted angle with respect to the seat chassis of up to 5 degrees.
19 . The armchair of claim 16 , wherein the seating structure in the operative position is projected upwards by up to 12 cm from the seat chassis.
20 . The armchair of claim 16 , wherein the sensor embedded in the seating structure is configurable to detect that no weight is on the seating structure for a period of time and to thereafter activate the first actuating device to automatically return the seating structure to a sitting position.
21 . The armchair of claim 16 , further comprising a chair back structure pivotally attached to a rear end of the seat chassis and to the support chassis.
22 . The armchair of claim 21 , further comprising a slider connected to the chair back structure.
23 . The armchair of claim 22 , further comprising a recliner actuator mounted to the chair back structure and connected to the seat chassis, the recliner actuator configured to bring the armchair to a reclining position.
24 . The armchair of claim 23 , wherein the slider comprises a wheel for allowing the slider to roll within a slot.
25 . The armchair of claim 24 , wherein the recliner actuator causes the slider to slide upwards in the slot and allows the seat chassis to pivot on the one or more support columns.
26 . The armchair of claim 16 , further comprising a footrest connected to a protracting end of a second actuating device mounted to the support chassis.
27 . The armchair of claim 26 , wherein the footrest is configured to lock in place at a specific position that helps secure a user from sliding down in the armchair.
28 . The armchair of claim 27 , wherein the footrest comprises a lip or friction surface to keep the user's feet on the footrest.
