Abstract

A cycle saddle which includes a cushioned part A on a base plate B is not fixed rigidly to the post E but can move in sympathy with the movements of the rider and of the cycle as a whole; the movement is limited and controlled by springs C, F, G. The height of the saddle may be adjusted by means of the bracket H and bar I. The saddle is shaped such that no part of the seating area passes between the thighs of the rider. <IMAGE>

Description

SPECIFICATION Improvements in and relating to seats for pedal cycles The subject of this invention is an improved seat for pedal cycles designed to eliminate saddle fatigue and to facilitate easier hill climbing through the use of extension springs strategically placed to give the said seat, two dimensional flexibility. The said seat is not fixed immovable, it rides freely, in that it can swivel and pivot to a limited degree, restricted and controlled by the said extension springs which automatically adjust to the bounce and incline of the cycle when in motion and also to the incline of the machine when hill climbing and also to the movement of the rider's thighs and rump. A main feature of the invention is that no part of the sitting area of the said seat passes between the thighs of the cycle's rider.The seat is covered with a stuffed cover of quality cloth, leather, or a suitable water proofed material suitably shaped, with the filling being of soft latex foam or other soft alternative.

The suggested area of the top of the seat is approximately; eighteen centimetres wide at the front, about eighteen centimetres along the sides and tapering down to about twelve centimetres at the back.

Fig. 1, of the accompanying drawings, shows a side aspect of the said invention mounted on a section of a cycle frame. The rigid base of the seat is the partly curved metal base plate as shown at - (B), which could be any suitable strong alternative. The plate has an indent as shown at - (D) with a small protrusion bent down to slot into the hole at the top of the seat heightening tube. The indent and protrusion are at the centre of the base plate from side to side and at least two thirds back from the front to back, as shown at (D).As the hole at the top of the seat heightening tube is larger than the protrusion, the seat is able to swivel and pivot freely but limited to a degree by the tensions imposed by the said extension springs, which are arranged as shown in fig. 1 by way of example only, they could of course be arranged differently and increased or decreased in number. The pair of springs -- (C) attached at the bottom to the bracket -- (H) stretch upwards, slightly forward and outward to opposite sides of the base plate - (B) to which they are secured and they are the main, swivel retarding springs.

The two springs -- (F) ARE the primary weight carrying springs. They also are attached to opposite sides of the base plate toward the rear and are anchored to the protrusion on the height adjusting bar - (I) as shown, which said bar, is also attached at the top, to the bracket -- (H) and also to the nut and bolt - (J) on the section of said cycle frame. These two springs should be set at sufficient tension to tilt the flat part of the base plate up at an angle not exceeding thirty degrees.

The two springs -- (G) are attached, right to the rear of the sides of the base plate - (B) and also are anchored to the protrusion on the bar - (I).

These springs can be slightly longer than the others and should not come on to tension until the seat is sat upon. They then act as a check and prevent the seat from dipping but allow the seat to bounce at the front to compensate for the unevenness of the terrain. The cushion part of the seat, a side aspect of which is shown at - (A), is covered with cloth, leather, or a water proofed material and filled with latex foam or any suitable soft alternative. The bar -- (I) could be dispensed with, but you would then of course be unable to higher the seat.

1. A seat for use on pedal cycles which is supported on extension springs arranged in a manner which allows the said seat to swivel and pivot to a degree limited and controlled by the said extension springs which cause the said seat to adjust automatically to the bounce and incline of the cycle when in motion. The seat has an attachment which enables it to be raised or lowered and the base is covered with material stuffed with a thick soft filling. A main feature of the invention is that no part of the sitting area of the seat extends between the thighs of the rider. A seat constructed and arranged as herein described with reference to the accompanying drawing.

2. A seat as in claim 1, constructed and arranged as herein described with reference to the accompanying drawing and with reference to claim 1, but in which the said seat is limited by restriction so as to pivot only.

3. A seat as described in previous claims but in which the said seat is limited by restriction so as to swivel only.

4. A seat as described in previous claims but in which the said seat has no attachment which enables the seat to be raised and lowered.

A seat constructed and arranged as herein described with reference to the accompanying drawing. 2. A seat as in claim 1, constructed and arranged as herein described with reference to the accompanying drawing and with reference to claim 1, but in which the said seat is limited by restriction so as to pivot only. 3. A seat as described in previous claims but in which the said seat is limited by restriction so as to swivel only. 4. A seat as described in previous claims but in which the said seat has no attachment which enables the seat to be raised and lowered. New claims or amendments to claims filed on 4 January 1 982. Superseded claims 1-4. New or amended claims:

1. In a bicycle having a mounting attachment for a seat, wherein the improvement comprises an improved seat mounted on said attachment comprising: a rigid flat base of metal or alternative rigid medium, suitably shaped for sitting on with the widest end at the front and narrowing off to the rear (and with no under frame), said base having strategically arranged holes along the rear and side edges; also a protrusion from the underside of the base at a point, central between the two side edges, and ideally just off centre between the rear and front end of the said base and rigid in relation to the base, but loose fitting in relation to the bicycle mounting attachment into the top of which it slots; the seat can rotate horizontally, and pivot vertically in an arc, in the way of a seesaw; extension springs, riveted or bolted to the strategically arranged holes around the base, are secured at the opposed ends to a bracket and extension bar; the bracket is secured around and near the top of the seat mounting attachment, and the extension bar, to the vertical part of the bicycle frame, into which the seat mounting attachment slides; all the springs are pulled taut before the bar attachment is secured; this draws the springs downwards and inwards with constant tension, to an area around the seat mounting attachment; as the load bearing springs are lower down than the two frontal springs, the front end of the seat tilts up at an angle, above the horizontal bar of the cycle, until restricted by the said frontal springs; which said springs also exert a braking and pull back tension on the rotating potential of the seat base, caused by the movement of the riders thighs and rump when pedalling; the sum total tension exerted by all the said springs, prevents any side rocking tendency; a loose or fixed cover for the base, possibly cloth, fabric, leather, or any other suitable material; any of which should be adequately water proofed; the cover is filled with, for exampie latex foam, or any suitable soft filling, the greater amount of which should be tightly compressed and fixed, over and around the front edges, of the seat base, which is the area of the rider's point of contact with the seat; this places the rider in a more forward position on the bicycle, and thereby, transferring the body weight of the rider directly over the forward down drive pedal; thus giving more power and much greater acceleration at the discretion of the said rider.

2. A seat for a pedal cycle constructed and arranged substantially as herein described with reference to the accompanying drawing and with reference to claim 1, except wherein the said springs are arranged different and could be increased or decreased in number.

3. A seat for a pedal cycle constructed and arranged substantially as herein described with reference to the accompanying drawing and with reference to claim 1, and claim 2, except wherein the protrusion could be a cup or both.

4. A seat for a pedal cycle constructed and arranged substantially as herein described with reference to the accompanying drawing and with reference to claims 1, 2, and 3, whereby the rotation potential of the base is totally restricted.

5. A seat for a pedal cycle constructed and arranged substantially as herein described with reference to the accompanying drawing.
