BACKGROUND OF THE INVENTION
(1) Field of the Invention
The disclosed inventive concept relates to seats, chairs, and devices used for cushioned and/or contoured support of certain parts of the human body. More particularly, the inventive concept herein is a specific design and construction of a seating device which supports the hamstring muscles and back of a user while simultaneously providing a concave bottom segment specifically contoured to the buttocks area of the anatomy. The disclosed device is intended to provide a supporting cushion and weight-bearing section for a person's thighs and back while the person is seated for extended periods of time. This particular design thereby eliminates or minimizes discomforting or painful contact of the buttocks area with a chair or other type of seating.
Devices are known that relate to seats and thigh supports. Some devices provide improved seat attachments consisting of two divided panels molded to curve up on the outer edge for those who have pain or discomfort sitting on a regular seat. Other devices provide seats having individual supports for the lower thigh of the user which are pivotally mounted at the front of the seat portion. However, these known devices provide a chair having a seat panel adapted to support the hamstrings and do not provide a seat that places the person's weight on the user's thighs rather than on their buttocks.

The objects, features, and advantages of the inventive concept presented in this application are more readily understood when referring to the accompanying drawings. The drawings, totaling five figures, show the basic components and functions of the device and methods of use. In the several figures, like reference numbers are used in each figure to correspond to the same component as may be depicted in other figures.
The discussion of the present inventive concept will be initiated with FIG. 1, which illustrates a front view of the seating device 1 in its open configuration. In the open configuration, the seating device 1 is receptive to a user 40 (not shown) sitting upon the seating device 1. The essential components of the seating device 1, as visible in FIG. 1, comprise a top panel 13, upon which a user's 40 thighs 45, 46 will rest; a contoured recess 12, which is contoured to correspond generally to a user's 40 buttocks 41, 42; an inner backrest 10, a back panel 11; a horizontally-oriented space 17; a left hinge 6 [shown in FIG. 5(c)] and left hinge bolt 8; a right hinge 7 (a right hinge bolt 9 is out of view); left and right armrests 2, 3; and left and right armrest supports 4, 5.
The contoured recess 12 is a solid, one-piece structure further comprising a top panel 13, a left side panel 15, a right side panel 16 not shown in FIG. 1), a forward front panel 14, a rear panel rear panel 18, and a continuous bottom edge 21.
FIG. 2 presents a left-side view of the seating device 1, again in the open configuration. The rightmost portion of FIG. 2 shows the inner backrest 10 and the back panel 11. The inner backrest 10 comprises an elastomeric exterior surface which encloses an underlayment of cushioning material, while the back panel 11 is composed of a rigid material for vertical structural integrity. The inner backrest 10 and back panel 11 are permanently joined in an abutting manner at a common interfacing surface 20.
FIG. 2 also shows the lower section of the seating device 1, which essentially is the contoured recess 12. As shown in FIG. 2, the contoured recess 12 comprises a solid, box-like structure having a front panel 14, a top panel 13, a left side panel 15, (the right side panel 16 is out of view), a rear panel 18, and a bottom edge 21, which edge 21 is common to the bottom of the left and right side panels 15, 16, the bottom of the front panel 14, and the bottom of the rear panel 18. The left armrest 2 is shown, being permanently attached at the angle shown, to a left armrest support 4. In turn, the left armrest support 4 is permanently attached to the left side of the top panel 13. In a corresponding manner, the right armrest 3 (not shown) is attached to a right armrest support 5, the right armrest support 5 being attached to the right side of the top panel 13.
In FIG. 2, the contoured recess 12 is shown to be an arcuate, transverse padded channel which runs the entire width from the left side to the right side of the seating device 1. The contoured recess 12 is a continuous structure shaped so as to generally correspond to the roundness of a user's buttocks. Again referring to FIG. 2, the upper half of the left hinge plate 6 is permanently attached to the left side of, and parallel to, the back panel 11. Both hinge plates 6, 7, may also be manufactured as an integral part of the back panel 11. The left hinge plate 6 is constructed with an aperture proximate the lower end of the left hinge 6 so as to accommodate the insertion of a left hinge bolt 8. By the same design, the upper half of the right hinge 7 [shown in FIG. 5(c)] is permanently attached to the right side of, and parallel to, the back panel 11. The right hinge plate 7 is constructed with an aperture proximate the lower end of the right hinge plate 7 so as to accommodate the insertion of a right hinge bolt 9.
In FIG. 2, both sides of the contoured recess 12, near the rear panel 18, are constructed with two threaded horizontal openings: one on the upper left side panel 15 and one on the right side panel 16. The threaded horizontal openings correspond to the threading of the previously-mentioned left hinge bolt 8 and the right hinge bolt 9, respectively. During manufacture, the back panel 11, having the left hinge plate 6 and right hinge plate 7 permanently attached, is lifted into a position directly above the rear panel 18, so as to align the respective apertures of the left hinge plate 6 and right hinge plate 7 with the threaded openings on the left-side and right-side panels 15, 16. The left hinge bolt 8 and right hinge bolt 9 are then inserted through the respective hinge apertures and into the threaded openings on the left-side and right-side panels 15, 16. The left and right hinge plates 6, 7, may be of a variety of different designs and construction, including an arrangement providing a spring-loaded attachment to the back panel 18 or to both side panels 15, 16 of the contoured recess 12. Further, the left and right hinge plates
In an alternative embodiment, the contoured recess 12 is configured with a horizontally-oriented circular channel extending the width of the seating device 1 from the rearmost portion of the left side panel 15 to the rearmost section of the right side panel 16. A corresponding circular, cross-sectioned rod 22 having a diameter corresponding to the inner diameter of said width-wise circular channel and a length corresponding to the length of said horizontally-oriented circular channel is included in the alternative embodiment. The said circular rod 22 further features exterior threading at both ends. The circular rod 22, once inserted into the circular channel, utilizes two threaded flat-head nuts 23, shown in FIG. 5(a), having internal threading corresponding to the exterior threads of said circular rod 22, to fasten both ends of the circular rod 22 securely against the left side panel 15 and right side panel 16 of the contoured recess 12.
Viewing FIG. 3, there is shown a user 40 in the motion of lowering the body onto the seating device 1, with the left hamstring muscles 45 approaching contact with the top panel 13 of the contoured recess 12. The left arm 43 of the user 40 assists in giving balance during the seating process by providing a gradual shift of the user's 40 center of gravity. Once seated, the user's back 47 will make contact with the cushioned inner back rest 10, and the buttocks 41 will be suspended directly over the concave portion of the contoured recess 12.
FIG. 4 illustrates a situation where the seating device 1 has been placed atop a chair 30 commonly found in residential or commercial settings. The back panel 11 of the seating device 1 is placed firmly against the chair back 33 and the bottom of the contoured recess 12 is placed in a level position upon the chair 30, corresponding to the horizontal of support provided by the chair 30 legs 34. A fully-seated user 40 is shown from the perspective of the right side of the seating device 1. The right hamstring muscles 46 of the user 40 are shown to be firmly supported by the top panel 13 of the contoured recess 12, and the back 47 of the user 40 may be firmly pressed against the cushioned back rest 10.
