Abstract
A chair including a support, a backrest with a backrest frame hingedly connected to the support, a seat bottom with a seat frame hingedly connected to the backrest and a bracket extending rearward from the seat frame, a linkage arm with a proximal end hingedly connected to the support at a fixed vertical position and a distal end hingedly connected to the bracket, and a return mechanism. Rotation of the seat bottom from a closed position to an open position causes, by way of interaction between the linkage arm and the bracket, the seat bottom to move forward from the support and the backrest to rotate about the support and recline.
Claims27
A chair, comprising:
- a support;
- a backrest including a backrest frame hingedly connected to said support;
- a seat bottom including a seat frame, hingedly connected to said backrest, and a bracket extending rearward from the seat frame;
- a linkage arm with a proximal end hingedly connected to said support at a fixed vertical position and a distal end hingedly connected to the bracket;
- a return mechanism to return said seat bottom from an open position to a closed position;
- wherein rotation of said seat bottom from the closed position to the open position causes, by way of interaction between said linkage arm and the bracket, said seat bottom to move forward from said support and said backrest to rotate about said support and recline.
A chair, comprising:
- a support having a front surface and a rear surface;
- a backrest adjacent to the front surface of said support and hingedly connected to said support via a first pivot fixed in position on said support, said backrest rotatable about the first pivot from an upright position to a reclined position without protruding beyond the rear surface of said support;
- a second pivot in a bottom portion of said backrest;
- and
- a seat bottom hingedly connected about the second pivot, said seat bottom rotatable about the second pivot from a stowed position in which a top surface of said seat bottom is adjacent to said backrest to an open position;
- wherein rotation of said seat bottom from the stowed position to the open position causes said seat bottom and said second pivot to move forward away from said support and said backrest to rotate about said first pivot to the recline position.
A chair, comprising:
- a support;
- a backrest hingedly connected to a top portion of said support;
- a cradle rigidly connected to a bottom portion of said backrest, said cradle being movable with respect to said support via the hinged connection between said backrest and said support;
- a seat bottom hingedly connected to said cradle including a bracket extending from a rear portion of said seat bottom;
- a linkage arm with a proximal end hingedly connected to said support and a distal end hingedly connected to the bracket;
- wherein rotation of said seat bottom from a closed position to an open position causes, by way of interaction between said linkage arm and the bracket, said seat bottom and said cradle to move forward from said support and said backrest to rotate about said support and recline;
- and
- a width between a rear surface of said backrest and a bottom surface of said seat bottom in the closed position is equal to or less than a width of said cradle.
