Abstract
A foldable chair includes a seat panel having a first end portion and a second end portion, a pivotable support having a first end portion and a second end portion, the first end portion of the pivotable support pivotally connected to the first end portion of the seat panel, and a variable resistance support assembly pivotally coupled to the second end portion of the seat panel for selectively raising and lowering the seat panel. The variable resistance support assembly can include a housing, with a first spring and a second spring stored therein. The first spring can have a first pressure load and the second spring can have a second pressure load that is less than the first pressure load.
Claims14
A foldable chair, comprising:
- a seat panel having a first end portion and an opposing second end portion;
- a pivotable support having a first end portion and an opposing second end portion, the first end portion of the pivotable support pivotally coupled to the first end portion of the seat panel;
- a variable resistance support assembly pivotally coupled to the second end portion of the seat panel, the variable resistance support assembly being compressible to selectively lower the second end portion of the seat panel in response to a force exerted by the user on the seat panel and configured to provide at least two levels of resistance as the second end portion of the seat panel is lowered;
- a base having a front, back, and opposing sides, the base being coupled to the variable resistance support assembly;
- a foot rest extending in a first direction from the base, wherein the foot rest comprises an L-shaped bracket detachably mounted to the base, the L-shaped bracket having a first section attached to the base and a second section having a central rib dividing the foot rest into left and right web sections for receiving the user's feet;
- and
- at least one brace leg extending from the base in a second direction opposite the first direction,
- wherein the second end portion of the pivotable support is pivotally coupled to the base.
A method of supporting a user above a floor surface, comprising
- providing a chair including:
- a seat panel having a first end portion and an opposing second end portion,
- a pivotable support having a first end portion and an opposing second end portion, the first end portion of the pivotable support pivotally coupled to the first end portion of the seat panel,
- a variable resistance support assembly pivotally coupled to the second end portion of the seat panel, the variable resistance support assembly being compressible to selectively lower the second end portion of the seat panel in response to a force exerted by the user on the seat panel and configured to provide at least two levels of resistance as the second end portion of the seat panel is lowered;
- a base having a front, back, and opposing sides, the base being coupled to the variable resistance support assembly;
- a foot rest extending in a first direction from the base, wherein the foot rest comprises an L-shaped bracket detachably mounted to the base, the L-shaped bracket having a first section attached to the base and a second section having a central rib dividing the foot rest into left and right web sections for receiving the user's feet;
- and
- at least one brace leg extending from the base in a second direction opposite the first direction,
- wherein the second end portion of the pivotable support is pivotally coupled to the base;
- lowering the second end portion of the seat panel from at least one elevated position to a lowered position in response to a motion of the user sitting on the seat panel;
- compressing the variable resistance support assembly to a first degree in response to a first amount of force exerted on the seat panel by the user during the sitting motion;
- and
- compressing the variable resistance support assembly to a second degree in response to a second amount of force exerted on the seat panel by the user during the sitting motion, the first amount of force being less than the second amount of force.
A foldable chair, comprising:
- a seat panel having a first end portion and an opposing second end portion;
- a pivotable support having a first end portion and an opposing second end portion, the first end portion of the pivotable support pivotally coupled to the first end portion of the seat panel;
- a variable resistance support assembly pivotally coupled to the second end portion of the seat panel, the variable resistance support assembly being compressible to selectively lower the second end portion of the seat panel in response to a force exerted by the user on the seat panel and configured to provide at least two levels of resistance as the second end portion of the seat panel is lowered;
- a base having a front, back, and opposing sides, the base being coupled to the variable resistance support assembly;
- a foot rest extending in a first direction from the base, wherein the foot rest comprises an elongate plate detachably mounted to the base, the plate having a major section extending towards the front of the foldable chair and a minor section extending towards the back of the foldable chair;
- and
- at least one brace leg extending from the base in a second direction opposite the first direction,
- wherein the second end portion of the pivotable support is pivotally coupled to the base.
