Cycle seat

A bicycle or tricycle seat comprising:

• a housing adapted to be attached to a bicycle;
• a first buttock-supporting member having a front end and a rear end thereof;
• means for operably pivotally attaching said rear end of first buttock-supporting member to said housing along a substantially horizontal axis;
• a second buttock-supporting member having a front end and a rear end thereof;
• means for operably pivotally attaching said rear end of said second buttock-supporting member to said housing along a substantially horixontal axis;
• coordinating means for supporting bottom portions of said first and second buttock-supporting member forwardly of said horizontal axes, said coordinating member comprising an elongated member pivotally attached intermediate the ends thereof along a substantially horizontal axis which is disposed generally transversely to and lower than said other horizontal axes, first support means disposed toward one end of said elongated member for supporting said bottom portion of said first buttock-supporting member, and second support means disposed toward the other end of said elongated member for supporting said bottom portion of the other of said second buttock-supporting member whereby when the front end of one of said buttock-supporting member moves downwardly by a certain distance, the front end of the other said buttock-supporting member will move upwardly by aproportional distance;
• the underside of said first and second buttock-supporting members being rigid and said first and second support means being in slideable contact with the underside of the respective first and second buttock-supporting members;
• stop means for limiting the degree of pivoting of said elongated member;
• first pitch adjustment means associated with said first supporting means for selectively adjusting the distance between the underside of said elongated member and the underside of said first buttock-supporting members;
• and
• second pitch adjustment means associated with said second supporting means for selectively adjusting the distance between said elongated member and the underside of said second buttock-supporting member.
