Abstract
A folding chair includes front and rear supports that fold and/or retract into central beams to reduce the space occupied by the chair in a folded configuration. A backrest is coupled to the central beams with a hub that allows an angle of the backrest relative to the central beams to be selected and for the backrest to be folded flat relative to the central beams. One or more actuators and pin actuators may control the relative movements of the backrest, front support, rear support, and central beams.
Claims23
A chair, comprising:
- a frame;
- a seating surface coupled to the frame;
- a backrest surface coupled to the frame,
- the frame having a backrest frame including a first portion and a second portion, wherein the first and second portions are connected together in a telescoping manner whereby the backrest frame includes a retracted position and an extended position;
- at least one blocking pin constructed and arranged to hold the backrest frame in the extended position;
- and,
- an actuator operatively coupled to the at least one blocking pin, the actuator configured to actuate the at least one blocking pin to allow the backrest frame to move from the extended position to the retracted position.
4 more elements
A chair, comprising:
- a frame having a backrest portion including a first portion and a second portion, wherein the first and second portions are connected together in a telescoping manner whereby the backrest portion has a retracted position and an extended position;
- at least one blocking component coupled to at least one of the first and second portions, the at least one blocking component constructed and arranged to allow the backrest portion to move from the extended position to the retracted position upon actuation of the at least one blocking component, wherein the at least one blocking component is constructed and arranged to hold the backrest portion in the extended position;
- and,
- an actuator operatively coupled to the at least one blocking component, the actuator configured to actuate the at least one blocking component to allow the backrest frame to move from the extended position to the retracted position.
1 more element
A chair, comprising:
- a frame having a backrest portion including a first portion and a second portion, wherein the first and second portions are connected together in a telescoping manner whereby the backrest portion includes a retracted position and an extended position, wherein the first portion comprises inner stiles and the second portion comprises outer stiles, wherein the inner stiles and outer stiles are constructed and arranged to slide relative to each other where the inner stiles slide into and out of the outer stiles to move the backrest portion between the retracted position and extended position, respectively;
- wherein the backrest portion further includes a rail connecting the outer stiles to form a U-shaped second portion of the backrest portion;
- at least one blocking pin constructed and arranged to hold the backrest portion in the extended position;
- and,
- an actuator disposed on the rail and operatively coupled to the at least one blocking pin via a tether, the actuator configured to actuate the at least one blocking pin to allow the backrest portion to move from the extended position to the retracted position.
2 more elements
A foldable chair, comprising:
- a backrest frame having a first stile and a second stile disposed at least partially inside the first stile and configured to slide in the first stile between an extended and a retracted position;
- a blocking pin movable between a blocking position and an unblocking position, wherein in the blocking position, the blocking pin cooperates with the first and second stiles to inhibit sliding motion of the second stile relative to the first stile, and in the unblocking position the second stile is free to slide relative to the first stile;
- a tether operatively coupled to the blocking pin at a first end;
- and
- an actuator operatively coupled to a second end of the tether, wherein the actuator is operable by a user to move the blocking pin between the blocking position and unblocking position.
