FIG. 3 is a side view of the seat accessory wherein the seat accessory comprises a replacement back portion of theseat 18. - The following is a discussion and description of the preferred specific embodiments of this invention, such being made with reference to the drawings, wherein the same reference numerals are used to indicate the same or similar parts and/or structure. It should be noted that such discussion and description is not meant to unduly limit the scope of the invention.
- Turning now to the drawings and more particularly to
FIG. 1 we have a perspective view of a seat duty belt accessory 20 for attachment to a back portion of aseat 18.FIG. 2 is a side view of the seat accessory 20 shown inFIG. 1 as viewed along line 2-2 when folded into an operative position. The seat accessory 20 minimizes excessive pressure on the lower back 16 of alaw enforcement officer 14 when an equippedduty belt 12 is worn. The seat accessory comprises: anupper back portion 24 having a thickness generally exceeding the thickness of the equippedduty belt 12; alower back portion 22 having a minimal thickness; and, a positioning and support means 26 to maintain theback portions seat 18. When theofficer 14 leans back, his back is supported largely by theupper back portion 24 of the seat accessory 20 and there is no excessive back pressure on his lower back as a result of the equippedduty belt 12 he is wearing. - Most preferably the positioning and support means 26 comprises a
strap 27 which is configured to extend around a back portion of theseat 18. Alternatively, the positioning and support means 26 might comprise a seat cover (not shown) containing theback positions -
FIG. 3 is a side view of the seat accessory wherein the seat accessory 20 comprises a replacement back portion of theseat 18. It is contemplated that the back portion of theseat 18 might be entirely replaced by a seat duty belt accessory 20. In this event the positioning and support means to maintain theback portions seat 18 would be an adaption on the seat accessory 20 so that the seat accessory 20 could attach to the bottom portion of theseat 18 in a manner similar to the way in which the original back portion of theseat 18, which had been replaced, was attached to the bottom portion of theseat 18. Such a seat duty belt accessory 20 might be produced by either an original equipment manufacturer, or alternatively, a secondary market replacement equipment manufacturer. - In the most preferred embodiment of the invention the seat accessory 20 further comprises a
bottom portion 28 foldingly attached to the bottom edge portion of thelower back portion 22 of the seat accessory 20. Arigid seat frame 30 extends around a peripheral portion of theback portions bottom portion 28 of the seat accessory 20. Hinges 32 attach the back portion of theframe 30 to the bottom portion of theframe 30. In the most preferred embodiment of the invention theframe 30 comprises flat bar which is ¾″×⅛″. - In has been found if the
lower back portion 22 of the seat accessory 20 has a height of 10″ and generally a 0″ padding thickness and the upper portion of the back portion of the seat accessory 20 has a height of generally 13″ and a maximum 3″ padding thickness 44 then an equippedduty belt 12 does not press into an officer's 14 back with excessive pressure. - While the invention has been described with preferred specific embodiments thereof, it will be understood that this description is intended to illustrate and not to limit the scope of the invention, which is defined by the following claims.
