Abstract
An adjustable chair device and method of use for supporting a user in either a traditional seated position in which a pair of legs of the user rest upon a floor, or in a relaxed seated position in which the legs of the user are supported above the floor, provides a base supporting an aft cushion assembly, a forward cushion assembly, and an upwardly extending seat back which cooperate to support the user in a seated position. The forward cushion assembly is adjustably attached to the aft cushion assembly with an adjustment assembly that allows both horizontal and vertical adjustment of the forward cushion assembly.
Claims19
An adjustable chair device for supporting a user in either a traditional seated position in which a pair of legs of the user rest upon a floor, or in a relaxed seated position in which the legs of the user are lifted with respect to the traditional seated position, the chair device comprising:
- a base supporting an aft cushion assembly, a forward cushion assembly, and an upwardly extending seat back;
- the aft cushion assembly providing an aft upwardly facing surface, the forward cushion assembly providing a forward upwardly facing surface, and the upwardly extending seat back providing a front facing surface, the aft upwardly facing surface, the forward upwardly facing surface, and the front facing surface cooperating to support the user in a seated position;
- and
- a means for adjusting the vertical position of the forward upwardly facing surface, while a user is sitting on the chair, between a first extreme position in which the forward cushion assembly contacts the aft cushion assembly and the forward upward facing surface is at the same vertical level as the aft upward facing surface, and a second extreme position in which the forward upward facing surface is in its entirety at a vertical distance from the aft upward facing surface.
An adjustable chair device for supporting a user in either a traditional seated position in which a pair of legs of the user rest upon a floor, or in a relaxed seated position in which the legs of the user are lifted with respect to the traditional seated position, the device comprising:
- a base supporting an aft cushion assembly, a forward cushion assembly, and an upwardly extending seat back;
- the aft cushion assembly providing an aft upwardly facing surface, the forward cushion assembly providing a forward upwardly facing surface, and the upwardly extending seat back providing a front facing surface, the aft upwardly facing surface, the forward upwardly facing surface, and the front facing surface cooperating to support the user in a seated position;
- a horizontal slide bar guide mounted on the aft cushion assembly;
- a slide frame having a horizontal slide bar that slidably engages the horizontal slide bar guide for horizontal adjustment of the slide frame;
- at least one vertical support arm attached to the forward cushion assembly and adjustably attached to the slide frame;
- and
- a means for adjusting the vertical position of the forward upwardly facing surface, while a user is sitting on the chair, between a first extreme position in which the forward cushion assembly contacts the aft cushion assembly and the forward upward facing surface is at the same vertical level as the aft upward facing surface, and a second extreme position in which the forward upward facing surface is in its entirety at a vertical distance from the aft upward facing surface.
A method for adjusting a chair device to support a user in either a traditional seated position or a relaxed seated position wherein a pair of legs of the user are supported above a floor, the method comprising the steps of:
- a) providing a chair device comprising:
- a base supporting an aft cushion assembly, a forward cushion assembly, and an upwardly extending seat back;
- the aft cushion assembly providing an aft upwardly facing surface, the forward cushion assembly providing a forward upwardly facing surface, and the upwardly extending seat back providing a front facing surface;
- a means for adjusting the vertical position of the forward upwardly facing surface;
- and
- a means for adjusting the horizontal position of the forward upwardly facing surface with respect to the aft cushion assembly;
- b) installing the base upon the floor;
- c) positioning the user upon the chair device such that the aft upwardly facing surface, the forward upwardly facing surface, and the front facing surface cooperating to support the user in a traditional seated position in which the legs of the user rest upon the floor;
- d) adjusting the horizontal position adjusting means to position the forward upwardly facing surface to contact a lower thigh portion of the legs of the user;
- and
- e) adjusting the vertical position adjusting means so that the forward upward facing surface is in its entirety at a vertical distance from the aft upward facing surface.
