Abstract
This is a split bicycle or tricycle saddle with left and right halves that move independently on a common pivot axis in a way that allows for more natural movement and posture of the human body during the foot operated pedal cycling activity. Each half of the saddle is shaped such that there is support behind the hip, capturing the ilium, as well as contact with the thigh which enables more power to be applied to the bicycle pedals when the cyclist is pedalling with the upper body fully upright in a more natural and comfortable position than the typical horizontal racing bicycle posture of the upper body. The resulting benefits from the said bicycle saddle arrangement are increased comfort, safety, better visibility, more power from the legs while both flexing and extending and less effort from the arms and chest muscles. In addition there is no pressure on the prostate and no damage to the testes so that male potency is unaffected as it is with other cycle seats which impact the sub-scrotal area.
Description
BACKGROUND OF THE INVENTION
Bicycles have been used worldwide for centuries. The cycling action of the human on a bicycle has in the past been one where the upper body remains upright with the face looking forward and hands resting naturally and in a relaxed way on a wide handle bar. Recent decades of bicycle frame and handlebar design have imposed a modified posture wherein the upper body is more horizontal with the face looking downward. The body in this posture is not in a relaxed state as it would be when standing or walking; the neck muscles are unnaturally straining to bring the face looking forward; the arms, hands and upper body are all bearing weight, and the lower spine and related muscles are constantly under tension in an effort to support a torso that is suspended between the hands and the crotch. This has lead to a more efficient way to apply power from the leg muscles to the pedals, but also requires the development of a different set of muscles that are more focussed on aiding leg muscles that are applying power to pedals. This modified posture of the upper body is normally associated with a wedge style bicycle seat intended to maximize blood flow to the major leg muscles while allowing support only to the pelvic bone in the sub scrotal area. Due to the adverse effects of intense pressure applied to this area that include penile numbness and infertility, there have been attempts in the past to move support to the normal seating area of the ischium of the inferior ramus of the pelvic bone. In particular these attempts have allowed the rider's weight to be distributed more evenly as low pressure over a larger seating area. Many split bicycle seat configurations have been designed in the past, such as described in the following documents found in the prior art:

This indeed is important for rider comfort, but continues to limit the force that can be applied to the foot pedals as there is only gravity and muscle power available as the means to apply force.
This invention builds on the prior art of rider comfort wherein gravity is removed as a limiting factor by capturing the ilium, therefore allowing greater force to be applied to the foot pedals.
BRIEF SUMMARY OF THE INVENTION
This invention is intended to allow for an upright posture of the rider in a more relaxed state similar to standing or walking, and in particular to assist with the application of power to the pedal by means of capturing the upper rear portion of the hip. This invention can also be used with the more modern posture of the upper body being more horizontal. In both cases this invention allows more power to be applied to the pedals by capturing the upper rear portion of the hip around the ilium. The uncaptured hip tends to move upward off the saddle during the downward power stroke of the leg muscles when the rider applies pressure to the foot pedal, said power being therefore limited by the combination of the rider's weight and gravity. This invention is a form of split saddle with left and right halves that move independently on a common pivot axis as the legs move alternatively. The mounting method consists of a horizontal pivot bar to which each saddle half is connected by means of two bearing blocks containing ball bearings to allow for rotational movement. Each seat half is located in a horizontal position by means of a spring when not bearing the rider's weight and cycling action. The pivot bar is connected to the stem with a connecting block.

This is a side plan view of the saddle as attached to the stem of a typical adult bicycle, with the right saddle half in a fully depressed position as is typical during the downward thrust of the rider's right leg when going through normal cycling activity, the left leg being in the upward position.

DETAILED DESCRIPTION OF THE INVENTION
The saddle is described in Figs. 1 and 2 operates as two independent support halves, the right saddle half 1 and the left saddle half 15. Fig. 2 details the exploded view of components, with the right side components enumerated and referenced therein, and the left side drawn and identifiable in the same manner as a mirror image of the right side. The seating surface of each saddle half is flexible and moulded to suit the human buttocks and rear upper hip area behind the ilium. The saddle halves 1 and 15 are mirror images of each other and each connect integrally with two metallic lower flange bearing blocks 2. Each of the bearing blocks are split, the two halves being 2 and 13 which captivate a ball bearing 7, and each of said bearing block halves fastened together with two machine screws 6 into threaded holes tapped vertically into the upper

BRIEF DESCRIPTION OF THE DRAWINGS
Fig 1. This is a side plan view of the saddle as attached to the stem of a typical adult bicycle, with the right saddle half in a fully depressed position as is typical during the downward thrust of the rider's right leg when going through normal cycling activity, the left leg being in the upward position.
Fig. 2. This is an exploded view of all components.
Fig. 3. Is a perspective view of the saddle as seen from underneath, attached to the stem.
DETAILED DESCRIPTION OF THE INVENTION
The saddle is described in Figs. 1 and 2 operates as two independent support halves, the right saddle half 1 and the left saddle half 15. Fig. 2 details the exploded view of components, with the right side components enumerated and referenced therein, and the left side drawn and identifiable in the same manner as a mirror image of the right side. The seating surface of each saddle half is flexible and moulded to suit the human buttocks and rear upper hip area behind the ilium. The saddle halves 1 and 15 are mirror images of each other and each connect integrally with two metallic lower flange bearing blocks 2. Each of the bearing blocks are split, the two halves being 2 and 13 which captivate a ball bearing 7, and each of said bearing block halves fastened together with two machine screws 6 into threaded holes tapped vertically into the upper
2 and lower 13 bearing blocks halves. When the saddle halves are assembled in the aforesaid manner to captivate the bearings, they may be slid onto the horizontal mounting bar 9 and positioned on the mounting bar to suit the rider's buttocks by means of spacer rings 8, and end collar 3, said end collar being fastened to mounting bar 9 by means of machine screw 10 which fastens through a vertical threaded hole in the end collar 3. During the assembly process, spring 4 is installed when the saddle half assembly is slid onto the horizontal mounting bar 9. As the said assembly with spring is slid onto position, spring block 5 is installed to captivate the rear facing spring end to slider bar 12. When the assembly is pressed together with pressure from end collar
3 towards the stem block 11, all spacers and bearings are intended to be captivated in a contiguous fashion, without any air gaps in between said spacers, bearings, stem block and end collar before the machine screw 10 is tightened. Stem block 11 is locked onto the standard bicycle or tricycle stem by means of fastening collar 14. The stem block is slotted beginning on the forward edge through to the vertical hole which accepts the stem, and the length of the slot matches the depth of the stem hole. The stem is fastened by means of a bolt and nut 16 which inserts into the block in a horizontal hole 17 that is ahead of the vertical stem hole. The bolt and nut 16 tighten together to decrease the diameter of the stem hole in the block thereby clamping the block on to the stem. The fully assembled saddle is shown in Fig. 3, with the standard bicycle stem shown attached to the fastening collar 14.
