Abstract
Abstract A support pad for relief of osteoarthritis of the hip joint, which connects the trochanter to the pelvis. The support pad has cushioning means for comfortable placement against the user's pelvis. The cushion has sufficient thickness so that when the user is lying on his side, it shifts body weight bearing pressure from the trochanter to the pelvis to reduce pressure on the hip joint, and thereby reduce pain in the joint. The support pad may have adjustable thickness to accommodate the anatomical geometry and weight of different users. A leg cushion may be used between the inner thighs to further reduce pressure in the hip joints.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
133 words
An arthritis relief support pad having length, width and thickness dimensions for placement on the pelvic crest of the pelvis of a user lying on his side on a supporting surface to shift body weight bearing pressure from the trochanter to the pelvis and thereby relieve pressure on the hip joint connecting the pelvis and trochanter, the support pad comprising: (a) cushion means for cushioning the pelvic crest and for lifting the pelvis relative to the supporting surface a distance sufficient to shift weight bearing pressure normally acting on the trochanter to the pelvis, said cushion having a top surface for placement against the crest of the pelvis and a bottom surface for placement against the supporting surface; and (b) a dimensionally stable base attached to the bottom surface of the cushion means.
Claim 2
Dependent Claim
133 words
An arthritis relief support pad having length, width and thickness dimensions for placement on the pelvic crest of the pelvis of a user lying on his side on a supporting surface to shift body weight bearing pressure from the trochanter to the pelvis and thereby relieve pressure on the hip joint connecting the pelvis and trochanter, the support pad comprising: (a) cushion means for cushioning the pelvic crest and for lifting the pelvis relative to the supporting surface a distance sufficient to shift weight bearing pressure normally acting on the trochanter to the pelvis, said cushion having a top surface for placement against the crest of the pelvis and a bottom surface for placement against the supporting surface; and (b) a dimensionally stable base attached to the bottom surface of the cushion means.
Claim 3
Dependent Claim
29 words
The support pad according to claim 1 wherein: (a) the support pad has a curved shape in the length dimension for following the circumferential curvature of the user's hip.
Claim 4
Dependent Claim
25 words
The support pad according to claim 1 wherein: (a) the pad has a length for wrapping around the user for placement on both pelvic crests.
Claim 5
Dependent Claim
59 words
The support pad according to claim 1 wherein: (a) the cushion means has two or more layers of cushion material stacked upon each other; and (b) two or more loops of cord running through the cushion material in the thickness dimension and along the longitudinal dimension for binding the cushion layers and the base into a unitary support pad.
Claim 6
Dependent Claim
50 words
The support pad according to claim 4 wherein: (a) the pad has a length of between approximately 12 and 15 inches; (b) the pad has a width of between approximately 3 inches and 5 inches; and (c) the pad has a thickness of between approximately 21/2 inches and 4 inches.
Claim 7
Dependent Claim
163 words
An arthritis relief support pad having length, width and thickness dimensions for placement on the pelvic crest of the pelvis of a user lying on his side on a supporting surface to shift body weight bearing pressure from the trochanter to the pelvis and thereby relieve pressure on the hip joint connecting the pelvis and trochanter, the support pad comprising: (a) cushion means for cushioning the pelvis crest and for lifting the pelvis relative to the supporting surface a distance sufficient to shift weight bearing pressure normally acting on the trochanter to the pelvis, said cushion having a top surface for placement against the crest of the pelvis and a bottom surface for placement against the supporting surface; (b) a dimensionally stable base attached to the bottom surface of the cushion means; (c) a leg cushion for placement between the user's inner thighs to reduce pressure between hip joint parts; and (d) strap means for attaching the cushion to the user's inner thigh.
Claim 8
Dependent Claim
163 words
An arthritis relief support pad having length, width and thickness dimensions for placement on the pelvic crest of the pelvis of a user lying on his side on a supporting surface to shift body weight bearing pressure from the trochanter to the pelvis and thereby relieve pressure on the hip joint connecting the pelvis and trochanter, the support pad comprising: (a) cushion means for cushioning the pelvis crest and for lifting the pelvis relative to the supporting surface a distance sufficient to shift weight bearing pressure normally acting on the trochanter to the pelvis, said cushion having a top surface for placement against the crest of the pelvis and a bottom surface for placement against the supporting surface; (b) a dimensionally stable base attached to the bottom surface of the cushion means; (c) a leg cushion for placement between the user's inner thighs to reduce pressure between hip joint parts; and (d) strap means for attaching the cushion to the user's inner thigh.
Claim 9
Dependent Claim
42 words
The support pad according to claim 6 wherein: (a) the leg cushion has thickness of between approximately 4 inches and 5 inches, a width of between approximately 4 inches and 5 inches, and length of between approximately 8 inches and 10 inches.
Claim 10

64 words
The support pad according to any one of claims 6 or 7 further comprising: (c) spacing means for creating adjustable support pad thickness to accomodate variations in greater trochanter lateral protrusion and weight among different users having: (i) one or more stacked spacers, and (ii) retaining means attached to the cushion means for attaching the spacers to the bottom surface of the cushion means.
Claim 11
Dependent Claim
15 words
The support pad according to claim 8 wherein: (a) the spacers comprise generally rigid material.
Claim 12
Dependent Claim
62 words
The support pad according to any one of claims 1-5 further comprising: (c) spacing means for creating adjustable support pad thickness to accomodate variations in greater trochanter lateral protrusion and weight among different users having: (i) one or more stacked spacers, and (ii) retaining means attached to the cushion means for attaching the spacers to the bottom surface of the cushion means.
Claim 13
Dependent Claim
15 words
The support pad according to claim 10 wherein: (a) the spacers comprise generally rigid material.
