AI Technical Summary

Benefits of technology

[0005]The present invention is a lift chair which allows the seated occupant to have a significantly more accommodating angle when transferring to a standing position to reduce the possibility of accidentally falling forward or ineffectively managing the weight transfer to a metal walker. Among other needs, the present invention specifically addresses the areas of hip or knee related mobility problems, especially among the elderly and obese, who may be living alone or want a degree of independence that does not require assistance from other individuals.

Problems solved by technology

Additionally, the seat angle allows the occupant's back to be tilted forward, but the hips and knees remain significantly behind the lower legs and feet, which means the occupant's center of gravity also remains behind the occupant's lower legs and feet, limiting the person's ability to safely exit from the chair.
This presents an even greater problem particularly with the elderly whose muscles and coordination have diminished with age.

Embodiment Construction

[0021]The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

[0022]A stand-up chair according to the present invention is shown in the Figures generally at 10. The chair 10 includes a first seat portion 12 and a second seat portion 14. The first seat portion 12 is connected to the second seat portion 14 with a first hinge 16. The first hinge 16 extends along the entire width of the seat portions 12, 14 as shown in the Figures. Also connected to the first seat portion 12 is a backrest 18; the backrest 18 is fixedly connected to the first seat portion 12, and does not move relative to the first seat portion 12. The backrest 18 includes at least one armrest 20 for supporting the arm of an occupant when sitting in the chair 10. The armrest 20 is also used for support when getting out of the chair 10 to stand up.

[0023]Connected to the second seat portion 14 is front cross member 36,...

Abstract

A chair having a first seat portion and a second seat portion pivotally connected to the first seat portion. The first seat portion and the second seat portion are movable between a first or lowered position and a second or raised position, and the first seat portion and second seat portion are disposed in substantially the same plane when the first seat portion and the second seat portion are in the first position. Also included is an actuator for moving the first seat portion and the second seat portion between the first position and the second position, and when the actuator is actuated, the first seat portion pivots relative to the second seat portion such that the first seat portion is located in a different plane relative to the second seat portion.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 281,831, filed Nov. 23, 2009, and U.S. application Ser. No. ______, which claims the benefit of U.S. Provisional Application No. 61 / 399,745, filed Jul. 16, 2010.FIELD OF THE INVENTION[0002]The present invention relates to lift chairs which are used to aid in going from a seated position to a standing position.BACKGROUND OF THE INVENTION[0003]There are several lift chair products that are currently in use in the marketplace. Typically, these lift chairs have a single flat seat which is lifted and rotated to allow the user to exit the chair with minimal effort. Additionally, the seat angle allows the occupant's back to be tilted forward, but the hips and knees remain significantly behind the lower legs and feet, which means the occupant's center of gravity also remains behind the occupant's lower legs and feet, limiting the person's ability to safely exit from the ch...
