Abstract

Many law enforcement officers have lower back problems arising from the habitual wearing of what is generally known as a “Sam Browne” duty belt. Workmen'"'"'s Compensation now presumes any lower back ailment suffered by a law enforcement officer was caused by a duty belt; and consequently, automatically covers such back problem. A duty belt seat accessory for minimizing excessive pressure on the lower back of a law enforcement officer when he wears a duty belt is disclosed. The seat accessory comprises: a lower back portion having a minimal thickness; an upper back portion having a thickness generally exceeding the thickness of the lower back portion and the equipped duty belt; and, a strap to maintain the back portion in an upright position adjacent to a seat. When the officer leans back his back is supported largely by the upper back portion of the seat accessory and there is no excessive back pressure on his lower back as a result of the equipped duty belt he is wearing.

Claims

1. A duty belt seat accessory for use with a bench vehicle seat having a seat back and a seat bottom, the seat accessory comprising:

a bottom edge portion;

a thoracic upper back portion having a substantial thickness;

a lumbar lower back portion disposed between the bottom edge portion and the thoracic upper back portion and having a thickness less than the thickness of the thoracic upper back portion, thereby creating a concavity adjacent the bottom edge portion and positioned so as to be behind the lumbar spine of a user seated on the seat bottom and against the seat accessory, to accommodate an equipped duty belt and to relieve pressure on the lumbar back caused by equipped duty belt, wherein the concavity is about ten inches high, measured in a direction extending from the bottom edge portion toward the thoracic upper back portion, the concavity extending laterally across the lumbar lower back portion such that no portion of the concavity between the thoracic upper back portion and the bottom edge portion protrudes forwardly of the thoracic upper back portion when the user is sitting against the seat accessory in a normal seating position; and

,

a support device configured to support the seat accessory such that the bottom edge portion is maintained against the seat back and adjacent to the seat bottom of the vehicle seat.

2. A seat accessory as in claim 1 wherein the support device comprises a strap which is configured to extend around a back and rear bottom portion of the seat.

3. A seat accessory as in claim 1 further comprising a bottom portion foldingly attached to the bottom edge portion of the lower back portion of the seat accessory.

4. A seat accessory as in claim 3 further comprising a rigid seat frame extending around a peripheral portion of the upper and lower back portions;

and the bottom portion of the seat accessory.

5. A seat accessory as in claim 4 wherein the lower and upper back portions, and the bottom portion of the seat accessory are hinged together by hinges attaching a back portion of the frame to a bottom portion of the frame to accommodate varying slopes of the lower and upper back portions with respect to the bottom portion of the seat accessory.

6. A seat accessory as in claim 5 wherein the frame comprises a flat bar.

7. A seat accessory as in claim 6 wherein the frame is made from flat bar ¾

″

in width and ⅛

8. A seat accessory as in claim 5 wherein the upper and lower back portions of the seat accessory further comprise wings which are foldingly attached to side portions of the back portions of the seat accessory.

9. A seat accessory as in claim 5 wherein the seat accessory further comprises magnets positioned centrally in the back portions of the seat accessory to reduce back pain.

10. A seat accessory as in claim 5 wherein one of the back portions in the seat is inflatable.

11. A seat accessory as in claim 5 further comprising a pump and a release valve so that volume and pressure of air in the back portion of the seat accessory may be controlled.

12. A seat accessory as in claim 5 wherein the upper and lower back and bottom portions of the seat accessory contain a bullet resistant fabric so that the seat accessory may be removed in an emergency situation and used as a shield against bullets by officers and wherein the support device comprises hook and loop type fasteners for quick removal in an emergency situation.

13. A seat accessory as in claim 1, wherein the concavity is about 4 inches deep relative to the thoracic upper back portion.

14. A seat accessory as in claim 1, wherein the bottom edge portion defines a lower edge of the seat accessory.
