SEATING ARRANGEMENTS FOR CYCLES, EXERCICE CYCLES, OTHER PEDAL-POWERED CONTRIVANCES AND THE LIKE CONTRIVANCES

摘要

A seating arrangement for a cycle or the like has a seat comprising a unitary saddle member (11) having a medial portion (14) with a support member attached to its underside for attaching it to a seat post. The support member may comprise a wire support (18). A pair of symmetrical wing portions (12, 13) extend laterally from the medial portion (14) and a nose portion (15) extends laterally from the medial portion (14) and a nose portion (15) extends forwardly from it. The wing portions (12, 13) are supported as cantilevers and curve outwards and upwards from the medial portion (14), preferably until their distal ends are at least 1.5 cm to 2.5 cm higher than the medial portion. Each wing portion (12, 13) is resiliently flexible to assume a substantially horizontal position under the weight of a rider. The leading edge (16, 17) of each wing portion (12, 13) may be swept back. Such wing portions (12, 13) provide for a greater degree of comfort because they do not concentrate the weight of the rider in one localized area, absorb vibration, and do not significantly inhibit movement of the lower buttocks and upper back of thighs as the rider pedals. In preferred embodiments, the seat is combined with a shock-absorbing seat post assembly comprising a shaft mounted telescopically in a tube and having a keyway extending longitudinally of the shaft between a first position within the end of the tube and a second position nearer the seat supporting end. A key located in the keyway engages the tube and limits rotation of the seat post while permitting reciprocating movement of the seat post relative to the tube.
