Abstract
Abstract The defecation process can be substantially faciltated by means of a specially contoured toilet seat which is completely adaptable to conventional toilets. The toilet seat has a hinge means for attachment to the toilet and an annular relatively planar section, conforming generally in peripheral configuration to the periphery of the bowl section of the toilet. The hinge post section positioned at the rear end of the toilet. The rear section of the toilet is upwardly and outwardly curved at a steep angle thereby preventing the user from sitting back on the rear section of the toilet seat. The top surfaces of the seat in the rear and side sections slope in an upwardly and outward direction but at a progressively smaller angle than the rear most section. At the front section of the seat particularly in the thigh support region, the surface of the seat is somewhat concave and in a region of the front section the seat slopes in a direction which is the reverse of the slope at the side and rear sections.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
101 words
In association with a conventional toilet bowl having a horizontal upper face located the normal chair-height distance above floor level: an improved toilet seat connected to the bowl to overlie the bowl upper face; the upper surface of said seat including a steeply-sloped dished upper rear surface area for supportive engagement with the user''s pelvis, two shallowly-sloped dished upper side surface areas extending forwardly upper the rear surface area for supportive engagement with the user''s buttocks, and two generally flat horizontal upper front surface areas extending forwardly and inwardly from the side surface areas for supportive engagement with the user''s thighs.
Claim 2
Dependent Claim
101 words
In association with a conventional toilet bowl having a horizontal upper face located the normal chair-height distance above floor level: an improved toilet seat connected to the bowl to overlie the bowl upper face; the upper surface of said seat including a steeply-sloped dished upper rear surface area for supportive engagement with the user''s pelvis, two shallowly-sloped dished upper side surface areas extending forwardly upper the rear surface area for supportive engagement with the user''s buttocks, and two generally flat horizontal upper front surface areas extending forwardly and inwardly from the side surface areas for supportive engagement with the user''s thighs.
Claim 3
Dependent Claim
28 words
The seat of claim 1 wherein the side and front upper surface areas are on approximately the same horizontal level so that the user''s thighs extend generally horizontally.
Claim 4
Dependent Claim
37 words
The seat of claim 1 wherein the rear surface area extends an appreciable distance above the side surface areas whereby the rear surface area exerts an extensive stress urging the user to bend forwardly at the waist.
Claim 5
Dependent Claim
30 words
The seat of claim 1 wherein the rear upper surface area has a slope angle of about 55*, and the upper side surface areas have slope angles of about 20*.
Claim 6
Dependent Claim
38 words
The seat of claim 1 wherein the thigh-supporting surfaces, measured from the inner edge of the seat to the outer edge, are about 5 inches in the horizontal direction; said thigh-supporting surfaces being spaced apart about 3 inches.
Claim 7
Dependent Claim
26 words
The seat of claim 1 wherein the upper rear surface area has a front-to-rear dimension, measured in a horizontal direction, of about one and one-half inches.
Claim 8
Dependent Claim
54 words
The seat of claim 1 wherein the front outer edges of the seat conform generally to the plan contour of the bowl to provide substantially no seat overhang; the thigh-supporting surfaces extending inwardly from the seat outer edge for a distance of about 5 inches; said thigh-supporting surfaces being spaced apart about 3 inches.
Claim 9
Dependent Claim
140 words
An improved toilet seat connectable to a conventional toilet bowl to overlie the bowl upper face; said seat being located on a generally horizontal level, and being generally u-shaped in top plan outline; the upper surface of said seat including a steeply-sloped dished upper rear surface area for supportive engagement with the user''s pelvis, two shallowly-sloped dished upper side surface areas extending forwardly from the rear surface area for supportive engagement with the user''s buttocks, and two generally flat horizontal upper front surface areas extending forwardly and inwardly from the side surface areas for supportive engagement with the user''s thighs; said front surface areas being spaced apart about 3 inches, and said front surface areas having inner surface zones that extend considerable distances rearwardly from the front edge of the seat to provide extensive supportive areas for the user''s thighs.
Claim 10
Dependent Claim
140 words
An improved toilet seat connectable to a conventional toilet bowl to overlie the bowl upper face; said seat being located on a generally horizontal level, and being generally u-shaped in top plan outline; the upper surface of said seat including a steeply-sloped dished upper rear surface area for supportive engagement with the user''s pelvis, two shallowly-sloped dished upper side surface areas extending forwardly from the rear surface area for supportive engagement with the user''s buttocks, and two generally flat horizontal upper front surface areas extending forwardly and inwardly from the side surface areas for supportive engagement with the user''s thighs; said front surface areas being spaced apart about 3 inches, and said front surface areas having inner surface zones that extend considerable distances rearwardly from the front edge of the seat to provide extensive supportive areas for the user''s thighs.
Claim 11
Dependent Claim
87 words
The seat of claim 8 wherein the rear upper surface area has a slope angle of about 55*, and the upper side surface areas of about 20*; the upper rear surface area having a front-to-rear dimension, measured in a horizontal direction, of about 1 1/2 inches; the space circumscribed by the aforementioned upper surface areas being a generally circular opening having a radius of about 4 1/2 inches; and said upper front surface areas extending forwardly of said circular opening for a distance of about 4 inches.
Claim 12
Dependent Claim
27 words
The seat of claim 9 wherein the steeply-sloped surface area has slope angle of about 55*, and the shallowly-sloped surface areas have slope angles of about 20*.
Claim 13
Dependent Claim
23 words
The seat of claim 10 wherein the thigh-supporting surfaces measure about 5 inches from the seat inner edge to the seat outer edge.
Claim 14
Dependent Claim
105 words
A toilet seat for positioning a conventional bowl, said seat having an outer peripheral edge and an inner peripheral edge; the upper surface of the seat including a steeply-sloped dished upper rear surface area extending from the seat outer edge to the seat inner edge for supportive engagement with the user''s pelvis; two shallowly-sloped dished upper side surface areas extending from the outer seat edge to the inner seat edge for supportive engagement with the user''s buttocks; and generally flat horizontal upper front surface areas extending rearwardly from the outer front seat edge to the inner seat edge for supportive engagement with the user''s thighs.
Claim 15
Dependent Claim
105 words
A toilet seat for positioning a conventional bowl, said seat having an outer peripheral edge and an inner peripheral edge; the upper surface of the seat including a steeply-sloped dished upper rear surface area extending from the seat outer edge to the seat inner edge for supportive engagement with the user''s pelvis; two shallowly-sloped dished upper side surface areas extending from the outer seat edge to the inner seat edge for supportive engagement with the user''s buttocks; and generally flat horizontal upper front surface areas extending rearwardly from the outer front seat edge to the inner seat edge for supportive engagement with the user''s thighs.
Claim 16
Dependent Claim
36 words
