Multiple sitting position chair

1. A reconfigurable chair, comprising:

a base;

a seat coupled to the base;

a rotatable backrest coupled to the seat;

a side mounted rest coupled to the seat, wherein, the side mounted rest is positioned laterally to the seat;

a first hinge coupling the side mounted rest to the seat, wherein:

the side mounted rest rotates upwardly around a first axis of rotation, defined by the first hinge, from a first position to a second position and to an indefinite number of positions between the first position and the second position, and

the first position is at an obtuse angle with an edge of the seat and the second position is at an acute angle with the edge of the seat;

a first housing coupled to the backrest;

a second housing coupled to the seat;

a post, wherein a first end of the post is coupled to the first housing and a second end of the post is coupled to the second housing;

a second hinge located in the first housing, wherein:

the second hinge defines a second axis of rotation,

the second axis of rotation is transverse to the first axis of rotation,

the second hinge is coupled to the backrest,

triggering an operation of the second hinge causes the backrest to rotate around the second axis of rotation, from a position perpendicular to a top surface of the seat, to a position parallel with the top surface of the seat and positions anywhere in between the position perpendicular to the top surface of the seat and the position parallel with the top surface of the seat;

a third hinge located in the second housing, wherein:

the third hinge defines a third axis of rotation,

the third axis of rotation is transverse to the first axis of rotation and parallel to the second axis of rotation,

the third hinge is coupled to the post,

triggering an operation of the third hinge causes the backrest to tilt in a range, away from or toward, the seat in a direction defined by the third axis of rotation,

the backrest is position able anywhere within the range, and

the back rest, in the position parallel with the top surface of the seat, and the seat, support a person sitting on the backrest in cooperation with the backrest being tilted away from the seat.

2. The reconfigurable chair of claim 1 , further comprising:

a gas piston coupled to the third hinge, wherein an actuation of the gas piston controls the range of tilt.

3. The reconfigurable chair of claim 1 , wherein the backrest is configured to move up or down, along a length of, or in line with, the post.

4. The reconfigurable chair of claim 1 , wherein the backrest, in the position parallel to the seat, is positioned higher than the seat.

5. The reconfigurable chair of claim 1 , wherein the backrest includes a cushion.

6. The reconfigurable chair of claim 1 , wherein the side mounted rest includes a cushion.

7. The reconfigurable chair of claim 1 , further comprising:

a lock, wherein the lock is configured to secure the side mounted rest in an upright position.

8. A reconfigurable chair, comprising:

a base;

a seat coupled to the base;

a post coupled to the seat;

a backrest coupled to the post;

a first hinge coupled to the post and to the backrest, wherein

the backrest is configured to rotate around the first hinge from a first, upright position of the backrest, to a second, flat position of the backrest;

a pair of side mounted rests coupled to the seat, each side mounted rest includes a second hinge, wherein:

a first of the side mounted rests is positioned on a left side of the seat,

the second side mounted rest is positioned on a right side of the seat, and

the first side mounted rest or the second side mounted rest is rotatable around an axis of the second hinge in positions including:

a first, upright position of the first or second side mounted rest,

a second, flat position of the first or second side mounted rest, and

an indefinite number of positions between the first, upright position of the first or second side mounted rest and the second, flat position of the first or second side mounted rest.

9. The reconfigurable chair of claim 8 , wherein each side mounted rest is configured to pivot from a respective edge of each side mounted rest coupled to the seat.

10. The reconfigurable chair of claim 9 , wherein the first side mounted rest pivots independently of the second side mounted rest.

11. The reconfigurable chair of claim 8 , wherein the side mounted rests, in a first position relative to the seat, a top surface of each side mounted rest follows a slope in alignment with a top surface of the seat.

12. The reconfigurable chair of claim 8 , further comprising a rotation point in a housing coupled to a support frame of the seat, wherein the backrest is configured to tilt forward or backward from the seat, in a range defined by the rotation point.

13. The reconfigurable chair of claim 8 , further comprising a height adjustment element coupling the backrest to the post, wherein a height position of the backrest is adjustable by operation of the height adjustment mechanism.

14. The reconfigurable chair of claim 8 , wherein at least one side mounted rest is configured to pivot upright while the backrest is positioned in the second, flat position.
