The invention claimed is: 1. An apparatus (1) for exercising abdominal muscles in a sitting position, the apparatus comprising: an elastic and expandable tensile belt (2) which is moved by a user by active muscular exertion, and a fastening means (3) for detachably affixing said tensile belt (2) to
The invention claimed is: 1. An apparatus (1) for exercising abdominal muscles in a sitting position, the apparatus comprising: an elastic and expandable tensile belt (2) which is moved by a user by active muscular exertion, and a fastening means (3) for detachably affixing said tensile belt (2) to a backrest (18) of a selected one of a chair, a car seat (19), and other article of seating furniture, wherein said tensile belt (2): a) is adapted to elastically constrain the abdominal muscles by exerting tensile force thereon, b) is adapted to engagingly encircle the waist of a user over no more than 270��, while a remainder of the waist is embraced by said fastening means (3), c) a respective connector element (7, 8) at each end thereof (12, 14), and d) an elastic strap (6) extending between said connector elements (7, 8); and wherein said fastening means (3) e) extend around the backrest (18) of the chair, the car seat (19) or the other article of seating furniture, and f) is provided with two mating connector elements (23, 24), each of which is compatible with a respective one of said mating connector elements (7, 8) of said tensile belt (2), and which separate a front part of the fastening means (3) between said connector elements (23, 24) from a back portion of said fastening means (3) beyond said connector elements (23, 24), wherein an elastic region is located at said front part of said fastening means (3), while said back portion of said fastening means (3) is nonelastic and neither stretches nor shifts as the abdominal muscles are exercised. 2. The apparatus in accordance with claim 1, wherein the length of said tensile belt (2) is adjustable. 3. The apparatus in accordance with claim 1, wherein said connector elements (7, 8; 23, 24) for attaching said belt (2) to the backrest (18) are provided with tongue elements (9) that prevent said connector elements (7, 8; 23, 24) from disconnecting on their own. 4. The apparatus in accordance with claim 1, further comprising a lordosis support (20) adapted to be fixed to said tensile belt (2) and to the backrest (18). 5. The apparatus in accordance with claim 4, wherein said lordosis support (20) is disposed between two of said connector elements (23, 24). 6. The apparatus in accordance with claim 4, wherein said lordosis support (20) comprises an inflatable air cushion. 7. The apparatus in accordance with claim 1, wherein said fastening means extends around the backrest (18) and is elastically implemented. 8. The apparatus in accordance with claim 7, wherein said fastening belt for affixing said tensile belt (2) to the backrest (18) is fastened to itself and is adapted to be slipped over the backrest (18). 9. The apparatus in accordance with claim 7, wherein said fastening means for affixing said tensile belt (2) to the backrest (18) is adapted to be fastened to itself and placed around the backrest (18). 10. The apparatus in accordance with claim 1 and further comprising two grip elements (4, 5), each comprising a mating connector element (26, 27), for connection to said mating connector element (7, 8) compatible therewith and disposed at the respective end (12, 14) of said tensile belt (2). 11. The apparatus in accordance with claim 1 wherein said fastening means further comprises a lordosis support.
