Bicycle seat cover assembly with triangular elastic under flap members

A bicycle seat cover assembly which is configured for rider comfort as well as for ease of installation and use, comprising:

• a seat cover of a generally flat triangular configuration narrowed to a tongue at its forward end and having both its forward and rearward extremities smoothly curved in a horizontal plane, including a cushion member, a top cover liner pulled tightly over said cushion member, a bottom cover liner adapted to engage the bicycle seat, and an exterior trim member extending about the entire periphery of said seat cover and attached to both said top cover liner and said bottom cover liner;
• a front under flap member extending horizontally beneath said tongue portion of said seat cover with its peripheral edge secured to said exterior trim member, and having an under trim member secured along its rearward edge, the ends of said under trim member also being secured to said exterior trim member;
• said seat cover being transversely bent throughout its length so as to be concave on its under surface, and said front under flap member together with said under trim member being in tension for maintaining said seat cover in its transversely bent condition;
• a crescent-shaped back under flap member extending transversely beneath the rearward end portion of said seat cover with its convexly curved rearward edge secured to said exterior trim member, said back under flap member normally lying loosely against said concave under surface of said seat cover, said back under flap member having its forward corners cut off to provide truncated ends, and having a back strap extending transversely of said seat cover and secured to said back under flap member along the concavely curved forward edge thereof;
• a pair of essentially triangular, highly elastic members disposed between said exterior trim member and respective truncated ends of said back under flap member, each of said triangular elastic members having one edge thereof secured to said exterior trim member and another edge thereof secured both to the associated truncated end of said back under flap member and to the associated end of said back strap, the remaining edge of each triangular elastic member being longitudinally stretchable so as to effectively provide a hinged support for the associated truncated end of said back under flap member;
• said seat cover assembly being installed upon a bicycle seat by first placing said front under flap member underneath the tongue of the bicycle seat;
• said back under flap member being adapted to be placed underneath the rearward end portion of the bicycle seat, whereupon said triangular elastic members are stretched to allow a hinged movement of the truncated ends of said back under flap member relative to said exterior trim member;
• and
• an adjusting strap disposed intermediate to said under trim member and said back strap, having respective end portions secured to said exterior trim member at respective sides of said seat cover assembly, a ring attached to one of its end portions, and its other end portion being of a hook and pile construction and being adapted to be pulled through said ring and fastened to itself in order to finely adjust the securing action of said adjusting strap.
