Abdominal exercise machine

Abstract

An abdominal exercise machine for exercising the abdominal muscles while the user is in a reclined position, which includes a stationary back pad having an upper surface and a lower surface, with a pair of handle bars attached to one end of the back pad. The upper surface of the back pad is for receiving the back of the person exercising. A seat pad is provided having an upper surface and a lower surface, with the lower surface having rollers attached thereto for allowing the seat pad to roll relative to the back pad. The upper surface of the seat pad is for receiving the seat of the person exercising. A pivot assembly is provided having a first support member attached to the bottom surface of the back pad, a second support member attached to the bottom surface of the seat pad, and a connecting pivot member pivotally connected to the first support member and fixedly connected to the second support member, wherein said connecting pivot member is pivotally connected to pivot relative to said back pad. In this manner, movement of the seat pad relative to the back pad by the person exercising allows the person to pivot and provides up to 180° of exercise movement to strengthen the abdomen and the abdominal muscles.

1 ) An abdominal exercise machine for exercising the abdominal muscles while the user is in a reclined position, comprising:
 a) a stationary back pad having an upper surface and a lower surface, with a pair of handle bars attached to one end of the back pad; the upper surface of said back pad for receiving the back of the person exercising;   b) a seat pad having an upper surface and a lower surface, with the lower surface having rollers attached thereto for allowing the seat pad to roll relative to the back pad; the upper surface of said seat pad for receiving the seat of the person exercising;   c) one end of said back pad and one end of said seat pad each having curved mating surfaces;   d) a pivot assembly having a first support member attached to the bottom surface of the back pad, a second support member attached to the bottom surface of the seat pad, and a connecting pivot member pivotally connected to the first support member and fixedly connected to the second support member, wherein said connecting pivot member is pivotally connected to pivot relative to said back pad;   e) movement of said seat pad relative to said back pad by the person exercising allows the person to pivot and provides up to 180° of exercise movement to strengthen the abdomen and the abdominal muscles.   
   
   
       2 ) An abdominal exercise machine in accordance with  claim 1 , wherein said back pad has 4 stationary foot supports on the bottom surface of said back pad. 
   
   
       3 ) An abdominal exercise machine in accordance with  claim 1 , wherein said seat pad has 4 rollers on the bottom surface of said seat pad. 
   
   
       4 ) An abdominal exercise machine in accordance with  claim 1 , wherein said pivot assembly includes a pivot screw or bolt extending through said connecting pivot member about which said seat pad pivots. 
   
   
       5 ) An abdominal exercise machine in accordance with  claim 1 , wherein said curved mating surfaces are in the shape of a concave curved surface and a convex curved surface for allowing said seat pad to pivot up to 180° relative to said back pad.
