A back support belt formed of a relatively rigid material having a width of 31/2 to 6 inches and a method of limiting the movement of a person in preventing lower back injury are disclosed. The belt reduces risk of lower back injury by restricting movement of the wearer, applying bio-mechanical directed forces to specific areas of the midsection and lateral trunk of the wearer and by utilizing pressure points which remind the wearer to use proper lifting techniques and good body mechanics.

1. A back support belt, comprising: an elongate support band which is 31/2 to 6 inches wide along the entire length thereof having a first and second longitudinal end, said support band being formed of leather which is 4 to 8 mm thick or being formed of a relatively rigid material having a similar stiffness as said leather; and tightening means for tightening said belt around a subject in a position wherein said first and second longitudinal ends of said support band overlap between 6 to 10 inches and said tightening means applys external pressure to both of said overlapping longitudinal ends of said belt when tightened. 2. The back support belt of claim 1, wherein said elongate support band is formed of a single piece of leather having a substantially uniform width along the entire length thereof. 3. The back support belt of claim 1, wherein said elongate support band has a substantially uniform width along the entire length thereof. 4. The back support belt of claim 1, wherein said tightening means includes a first tightening strap connected with one longitudinal end of said support band and means for adjustably fastening said tightening strap to said elongate support band. 5. The back support belt of claim 4, wherein said tightening means further includes a second tightening strap connected with the other longitudinal end of said support band. 6. The back support belt of claim 5, wherein said second tightening strap contains a buckle having a width smaller than the width of said support band. 7. The back support belt of claim 1, wherein said support band is formed of a strip of leather having a thickness of about 4-8 mm. 8. A back support belt, consisting essentially of: a generally straight elongate support band which is 31/2 to 6 inches along the entire length thereof and having first and second longitudinal ends, said support band being formed of leather which is 4-8 mm thick or being formed of a relatively stiff material having a similar stiffness as said leather; and tightening means for tightening said belt around the midsection of a subject in a position wherein said first and second longitudinal ends of said support band overlap between 6 to 10 inches and further wherein said tightening means urges both of said overlapping longitudinal ends of said belt against the abdomen of a subject when being worn by a subject to increase the intra-abdominal pressure in said subject. 9. The back support belt of claim 8, wherein said elongate support band is formed of a strip of leather having a thickness of about 4-8 mm. 10. The back support belt of claim 8, wherein said elongate support band has a substantially uniform width along the entire length thereof. 11. The back support belt of claim 8, wherein said elongate support band is formed of a strip of leather having a thickness of about 6 mm. 12. A method for limiting the movement of a person and preventing lower back injury, comprising the steps of: applying to a person to be treated the back support belt of claim 1; and positioning and tightening said belt on said person to increase the intra-abdominal pressure of said patient. 13. A method for limiting the movement of a person and preventing lower back injury, comprising the steps of: applying to a person to be treated the back support belt of claim 1; and positioning and tightening said belt on said person to increase intra-abdominal pressure wherein anteriorly said belt applys pressure to the sternal half of the tenth rib and the anterior portion of the iliac crest to restrict excessive forward bending, laterally said belt extends distally from the inferior border of the lateral portion of the tenth rib to the iliac crest to slightly limit lateral trunk motions occurring in the thoraco lumbar and lumbar areas wherein the pressure from said belt along the inferior border of the tenth rib and the superior border of the iliac crest acts to remind said subject of the allowable and safe limits of lateral flexion and rotation, and posteriorly the edges of said belt extend distally from the thoraco lumbar joint to the fifth lumbar joint to limit excessive extension of the lumbar spine and decrease lordosis and wherein pressure areas of the inferior edge of the dorsal portion of the twelfth rib and the sacral iliac line of the ilium serve as a reminder to said person when excessive extension of the spine is attempted. 14. The method of claim 12, wherein when said belt is applied to said person a space exists between said support band and the lumbar vertebral spinous processes of said person and when said belt is tightened said intra-abdominal pressure presses against the spine of said person to reduce the lordosis which is allowable by said space. 15. The method of claim 13, wherein the two longitudinal ends of said belt are overlapped between 6 to 10 inches on the abdomen of said person and both overlapped portions are pressed against the abdomen of said person to increase intra-abdominal pressure. 16. The back support belt of claim 1, wherein the upper and lower edges on the front and lateral portions of said belt are not padded. 17. A back support belt comprising: a generally straight elongate support band having first and second longitudinal ends which is 31/2 to 6 inches wide along the entire length thereof and which is formed of leather which is 4 to 8 mm thick or formed of a material which has similar rigidity characteristics as said leather; first connecting means attached to said belt at a point of attachment which is 5 to 11 inches from said first longitudinal end of said support band to thereby define a first longitudinal flap extending from said point of attachment to said first longitudinal end; and second connecting means attached to said second longitudinal end of said support band adapted for connection with said first connecting means, said first and second connecting means being arranged on said support band in a manner such that said first and second connecting means can be connected in a manner such that said first and second longitudinal ends can be overlapped an amount of from 5 to 11 inches and both of said longitudinal ends of said support band apply pressure to the abdomen of a wearer. 18. The back support belt of claim 17, which comprises a first connecting strap having a width less than the width of said belt, a second connecting strap having a width less than the width of said belt and means for adjustably connecting said first and second straps. 19. A back support belt, comprising: a generally straight elongate support band formed of leather having a thickness of 4 to 8 mm which is 31/2 to 6 inches wide along the entire length thereof, said elongate support band having first and second longitudinal ends and wherein the upper edges of the sides of the belt are not padded; a first strap attached to said belt at a point of attachment which is 5 to 11 inches from said first longitudinal end thereof thereby defining a first longitudinal flap extending from said point of attachment to said first longitudinal end; a second strap attached to said second longitudinal end of said support band; and means for adjustably connecting said first and second straps whereby said first longitudinal flap can overlap said second longitudinal end an amount of 5 to 11 inches. 20. The back support belt of claim 19, wherein the lower edges of the sides of the belt are not padded. 21. The back support belt of claim 19, and further comprising an abdominal pad to the stomach side of said first longitudinal flap.
