Abstract
A thrust support for bicycles against which the rider may press his buttocks at the same time he exerts the muscular force of his legs upon the pedals so as to accomplish additional driving power, thereby exerting less upper body energy and maintaining proper seat position.
Claims5
A thrust support for attachment to a conventional cycle seat comprising:
- a U-shaped member having a pair of spaced legs interconnected at one end by a bight,
- said member comprising a hollow tubular configuration bent along its length to cause the free end of its legs to extend laterally therefrom in a common direction,
- means secured to and extending between the legs of said member,
- said means detachably engaging the back edge of the seat for limiting relative motion between the seat and the thrust support, and
- the free ends of each of said legs being cut away to form concave configurations along a given part of their lengths which surround a part of a tubular frame of the seat when the thrust support is clamped in position.
