Abstract
Sitting and kneeling chair allowing quick and frequent transition between two core configurations, between at least sitting and kneeling positions with adjustability, without leaving the chair. Knee pads have inverting knee assembly with front and rear ends, that uses a knee pad pivot, follower, and knee linkage coupling with and upper portion of a frame below the seat assembly for travel between the upper portion of the frame and the lower portion of the frame above a base where each knee pad may be deployed from and between deployed and inverted orientations.
Claims20
A sitting and kneeling apparatus, comprising:
- a seat cushion having a front portion and a rear portion;
- a seat assembly connected under the seat cushion;
- a frame support structure having an upper portion located below said seat assembly;
- an adjustable height element at said frame support structure;
- a base receiving the adjustable height element, said base supporting the adjustable height element above a substantially horizontal floor surface for raising and lowering said frame support structure with said seat cushion and seat assembly, said frame support structure having a lower portion located above said base;
- a first knee pad having a front portion and a rear portion for a deployed orientation where the front portion is above the rear portion with the front portion extending outwardly from the frame support structure, and an inverted orientation where the front portion is below the rear portion for storage with the front portion near the base and the rear portion alongside the frame support structure and below said seat assembly;
- a second knee pad having a front portion and a rear portion;
- a knee linkage;
- a frame support pathway at said frame support structure;
- a first inverting knee assembly connected under the first knee pad, said first inverting knee assembly having a front end and a rear end, said first inverting knee pad assembly having a first knee pad pivot at the front end of said first inverting knee assembly and a first knee pad follower at the rear end of said first inverting knee assembly, said knee linkage coupling the first knee pad pivot with the upper portion of said frame support structure below said seat assembly, with the first knee pad follower at the frame support pathway for travel between the upper portion of said frame support structure and the lower portion of said frame support structure above said base;
- a second inverting knee assembly connected under the second knee pad;
- and
- a first knee pad grip at the first inverting knee assembly for alternately positioning the first knee pad between the deployed orientation and the inverted orientation with the first knee pad follower traveling the frame support pathway between the upper portion of said frame support structure and the lower portion of said frame support structure.

A sitting and kneeling method, comprising the steps of:
- connecting a front portion and a rear portion of a seat cushion into a seat assembly;
- supporting the seat assembly atop an upper portion a frame;
- adjusting a height of the seat assembly from a lower portion the frame at a base thereof above a substantially horizontal floor surface for raising and lowering the frame with the seat assembly;
- providing a first knee pad having a front portion and a rear portion for a deployed orientation where the front portion is above the rear portion with the front portion extending outwardly from the frame, and an inverted orientation where the front portion is below the rear portion for storage with the front portion near the base and the rear portion alongside the frame and below the seat assembly;
- providing a second knee pad having a front portion and a rear portion;
- connecting a first inverting knee assembly under the first knee pad where the first inverting knee assembly has a front end and a rear end, the first inverting knee pad assembly having a first knee pad pivot at the front end of the first inverting knee assembly and a first knee pad follower at the rear end of the first inverting knee assembly;
- coupling a knee linkage at the first knee pad pivot with the upper portion of the frame below the seat assembly, with the first knee pad follower at a frame pathway on the frame for travel between the upper portion of the frame and the lower portion of the frame above the base;
- and
- moving the first inverting knee assembly for alternately positioning the first knee pad between the deployed orientation and the inverted orientation with the first knee pad follower traveling the frame pathway between the upper portion of the frame and the lower portion of the frame, and connecting a second inverting knee assembly connected under the second knee pad for moving with the first inverting knee assembly for alternately positioning the second knee pad between the deployed orientation and the inverted orientation with the second knee pad follower traveling the frame pathway between the upper portion of the frame and the lower portion of the frame.
