Abstract
A collapsible chair has a seat (102), rear leg (110), and an armrest (160), and further has a back support element (120) and a pair of lateral cross braces (130, 140). The back support element is pivotally coupled to the rear leg, and the lower end of the back support element is movably guided along one first cross brace by a guiding element (150), while the armrest is coupled to the upper end of the other cross brace. Preferred collapsible chairs include a footrest (180) that moves upward and forward, when the backrest reclines. A locking mechanism (170) provides for reclining of the back support among a continuous set of positions.

A reclining chair comprising:
- a seat, a rear leg, an armrest, a reclining back support element having a lower end, and a first lateral cross brace and a second lateral cross brace, each of the cross braces having an upper end and a lower end;
- wherein the first and second lateral cross braces are pivotably coupled to the rear leg, and wherein the first and second lateral cross braces are pivotably coupled to each other;
- wherein the back support element is pivotally coupled to the rear leg, and wherein the lower end of the back support element is movably guided along the first cross brace by a guiding element;
- and
- wherein one portion of the armrest is coupled to the upper end of the second lateral cross brace, wherein another portion of the armrest is coupled to the chair via a connector element, and wherein the armrest substantially remains in the same attitude when the back support element reclines, and;
- wherein the reclining chair collapses in a single movement.
A method of reclining a collapsible chair having a seat, a back support element, an armrest, and a back support coupled to the back support element, comprising:
- mechanically coupling the back support element to a leg such that a movement of the back support element is associated with reclining of the back support;
- providing a guiding element and a locking member that cooperate with a lateral cross brace to provide locking of the back support element at a substantially continuously variable set of reclining positions
- wherein the lateral cross brace is pivotably coupled to the rear leg;
- coupling one portion of the armrest to the lateral cross brace and another portion of the armrest to the chair via a connector element;
- and
- wherein the armrest substantially remains in the same attitude when the back support reclines.
A collapsible reclining chair having a seat coupled to a back support, and an armrest coupled on one portion to a lateral cross brace that is pivotably coupled to a rear leg, wherein the chair collapses in a single movement when the seat pivots towards the back support, and wherein the armrest substantially remains in the same attitude when the back support reclines.
