Abstract
Abstract A spinal support device (10) for applying a directed and concentrated force on the sacrum to position the sacrum and pelvis to thereby establish a desired spinal posture when in a seated position. The device comprising a rigid support member (44) and a brace member (32) to which the rigid support member is attached. The device provides isolatable force on the sacrum from the sacral base line downwardly to a bottom seat surface and for a width across an individual's back approximately equal to twice the dimension of the posterior portion of the individual's sacrum.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
70 words
A spinal support device for applying support pressure to the sacral portion of the spine, comprising a rigid support member (44, 86,144) having rear and bottom surfaces (44,64) adapted to engage with back and bottom portions (14,12) of a seat and a shaped front surface (58) for applying support pressure to the sacral portion of the spine, and means (34,66) for locating the rigid support member (44,86,144) in the seat.
Claim 2
Dependent Claim
23 words
A support device according to claim 1 wherein the front surface of the rigid support member comprises an anatomical conforming front surface (88).
Claim 3
Dependent Claim
30 words
A support device according to claim 1 or 2 further including a padding member (46,88,170,172) positioned so as to extend across at least a portion of said front surface (58).
Claim 4
Dependent Claim
26 words
A support device according to any preceding claim wherein the locating means comprises a flexible seat locating member (66) extending from the rigid support member (44).
Claim 5
Dependent Claim
38 words
A support device according to any of claims 1 to 4 wherein the locating means comprises a brace member (30) which includes an upstanding portion (32) attached to said rigid support (44) and a seat engaging portion (34).
Claim 6
Dependent Claim
15 words
A support device according to claim 5 wherein said seat engaging portion (34) is flexible.
Claim 7
Dependent Claim
31 words
A support device according to any preceding claim wherein the rigid support member (44, 86, 144) has a top portion that has a greater width dimension than a bottom portion thereof.
Claim 8
Dependent Claim
33 words
A support device according to any preceding claim wherein said rigid support member (44, 86, 144) further includes a bulbous portion (62) extending anteriorly from a lower portion of the front surface (58).
Claim 9
Dependent Claim
22 words
A support device according to any preceding claim in which the rigid support member (144) forms an integral part of a seat.
Claim 10
Dependent Claim
45 words
A spinal support device for applying specific support pressure to the sacral portion of the spine comprising a rigid support member (44, 86,144) having at least top, opposing side and front surfaces and a brace member (30,90,140) to which said rigid support member is attached.
Claim 11
Dependent Claim
83 words
A sacral support for use with a seat having back and bottom portions directing and concentrating force anteriorly on the posterior of the sacrum comprising a rigid member (44,86,144) having seat contacting rear and bottom surfaces (44, 64) and a shaped anterior surface (58) that extends from a position substantially level with the sacral base line to the surface of the bottom seat portion (12) and horizontally a distance of about twice the posterior portion of the sacrum adjacent the sacral base line.
Claim 12
Dependent Claim
69 words
A sacral support device for exerting isolatable pressure on a designated spinal area comprising a rigid support member (44,86,144) having at least top, opposing sides and front surfaces, said front surface (58) having an anatomically accommodating curvature and an inflatable member (48,84,162) extending at least partially about said top and opposing side surfaces and a seat accommodating frame member (30,90,140) to which said rigid support member (44,86,144) is attached.
Claim 13
Dependent Claim
48 words
A spinal support device comprised of a rigid block (44,86,144) having top, bottom, opposing side, front and rear surfaces, said top (56) having a width dimension that is wider than the width of said bottom (64), said front surface (58) having a concave top to bottom extending curvature.
Claim 14
Dependent Claim
108 words
A lower back support mechanism for use with a seat having interconnected back and bottom portions (14,12) comprising: a rigid support member (44) having a generally concave front surface (58) having upper and lower sections, said lower section (62) extending anteriorly of the upper section (60); said support member further including a seat locating member (66) extending therefrom so that when said locating member is positioned between the back and bottom portions (14,12) said support member can be positioned on the seat relative to a user of the seat and relative to the back and bottom portions to produce localized pressure on the sacrum of the seat user.
Claim 15
Independent Claim
68 words
A method of supporting the neuro-musculo-skeletal system to produce pelvic stability in a seated position comprising the steps of placing a rigid support member (44,86,144) at the juncture of a back and bottom portion (14,12) of a seat, and positioning the rigid support member (44,86,144) relative to an individual in the seat so that force is applied by the rigid support member against the sacrum of the individual.
