DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The swing chair generally has a seat 20. The seat includes three pivotally connected panels comprising: a seatback 21, a seat middle 22 and a seat lower 23. Each seat panel is made of a seat frame 27 preferably made of metal, and a seat fabric 26 that is preferably UV resistant. The seat 20 has a seat armrest 24. The seat armrest 24 is pivotally connected to the seat back 21. The seat armrest is also pivotally connected to the seat armrest support 25. A sway bar 28 connects between the left and right sides of the seat middle 22. Seat armrest 24 forms a four bar mechanism being pivotally connected with the seat back 21, the seat middle 22, and the seat armrest support 25.

A user can recline on the seat. Reclining allows the user to lay almost prone. The seat is suspended from a frame. The support frame 50 has a front right vertical support 51, a front left vertical support 52, a rear left vertical support 53, and a rear right vertical support 54. The left horizontal support 55 connects between the rear left vertical support 53 and the front left vertical support 52. The right horizontal support 56 connects between the front right vertical support 51 and the rear right vertical support 54. The rear horizontal support 58 connects between the rear left vertical support 53 and the rear right vertical support 54. The vertical supports are generally vertical, and bent or angled inward so that they meet at an apex crossbar which is an upper horizontal support 57.

The seat 20 is hung from the upper horizontal support 57. The upper horizontal support 57 has a left suspension spring 65 and a right suspension spring 66 suspended from it. The left suspension spring 65 is connected to a left suspension connector 67. The right suspension spring 66 is connected to a right suspension connector 68. The right suspension connector 68 supports the front right suspension member 63 and the rear right suspension member 64. The left suspension member 67 supports the front left suspension member 61 and the rear left suspension member 62.

The left suspension members are connected to the left side of the seat 20. The right suspension members are connected to the right side of the seat 20. The front suspension members are connected to the front side of the seat 20. The rear suspension members are connected to the rear side of the seat 20. The rear suspension members are connected behind the rear lower hinges 34. The front suspension members are connected behind the armrest front lower hinges 33. Therefore, the pair of rear lower hinges 34 are located between where the front suspension members and the rear suspension members connect to the seat 20. The left suspension members and the right suspension members suspend the seat middle 22 in a rearward tilt. The seat middle 22 has a bowed front member 36 that has a downward curve.

The armrest has an armrest front upper hinge 31 connecting the seat armrest 24 to the seat armrest support 25. The seat armrest support 25 is rigidly connected to or is integrally formed with the seat lower 23. The pair of seat armrest rear upper hinges 32 connects the seatback 21 pivotally to the seat armrest 24. The armrest lower front hinges 33 pivotally connect the seat lower 23 and seat armrest support 25 to the seat middle 22. The seat middle 22 is pivotally connected to the seat back 21 at the rear lower hinges 34.

This invention can be made of metal or plastic or wood parts. The hinges can have angle limiting features. The hinges can be adjustable for tension control so that various resistance is provided to the reclining mechanism.

Additionally, the swing chair can have a foot rest. The seat lower panel 23 can have a foot rest 71 connected across the lower portion of the seat lower panel 23. The foot rest 71 can be connected from a right side to a left side of the lower portion of the seat lower panel 23. The foot rest 71 can mounted to pivot on foot rest pivots 73. A pair of foot rests can be used when a double chair for a pair of persons is being implemented. The foot rests in a double chair can be made to be freely movable.

Additionally, the armrest front upper hinge 31 can be mounted to an inside surface 72 of the seat armrest 24. Also, a locking mechanism 74 can connect the seat armrest 24 to the seat middle 22 or another part of the swing chair so that the backrest is locked in upright position to provide back support. The locking mechanism 74 can be formed as a bar that connects between various members to form a frame, or the locking mechanism 74 can be formed as a pin that inserts into a pair of holes to lock various members together to provide an upright position of the back support.

As seen from the figures, the four bar mechanism is formed between pairs of generally parallel members. The lower seat panel maintains a parallel relationship with the seatback panel in both the reclining position and upright position. The seat middle 22 maintains a generally parallel relationship with the armrest 24 in both the reclining position and the upright position. A parallelogram is formed by the four bar mechanism which provides a lack of upward bias due to its geometric configuration. The seatback can recline to a generally horizontal position that lacks an upward bias, which allows the user to recline like the user is floating on a cloud. The lower seat panel is pivotally below the back panel.

The armrest front upper hinge 31 is spaced apart from the armrest front lower hinge 33 by the front four bar mechanism member 35. The front four bar mechanism member 35 is a part of the seat armrest support 25 that extends downward to the seat lower 23. The front four bar mechanism number 35 located from the armrest front upper hinge 31 to the armrest front lower hinge 33 is preferably approximately the same length as the distance from the armrest rear upper hinge 32 to the rear lower hinge 34. Similarly, the armrest 24 is located between the armrest front upper hinge 31 and the armrest rear upper hinge 32. The armrest 24 is the same length as the portion of the seat middle 22 that is located between the armrest front lower hinge 33 and the rear lower hinge 34. The armrest is mounted above the seat middle panel 22. The seat middle panel 22 has a tubular frame. The pair of armrests is pivotally mounted to the seatback at the armrest rear upper hinge 32, which in turn is pivotally mounted to the seat middle panel 22 at the rear lower hinge 34, which in turn is mounted to the lower seat panel at the armrest front lower hinge 33, which in turn is mounted to the pair of armrests at the armrest front upper hinge 31.

From an upright position, the pair of armrests move rearward and downward to a reclined position while maintaining a generally parallel relationship to the seat middle panel 22.
