Abstract
The disclosure relates to a bicycle seat having a narrow front portion which broadens to a wider rear portion. A central cut-out (c) of arrowhead shape is formed in the seat to provide relief for an occupants external genitalia. An elevated hump structure (7) is also included on the seat surface to provide a rest for the superficial perineal space of an occupant. The particular structural characteristics of the seat improve the qualities of seat design and user comfort.
Description

ARROWHEAD BICYCLE SADDLE
Background of the Invention
This invention relates to bicycle seats. More specifically, this invention relates to improvements in the saddle portion of a bicycle seat and is intended to improve the qualities of seat design and user comfort.
At the present time, many general purpose bicycle saddles and high performance bicycle saddles are designed with a narrow leading end portion, a central transition portion and a wider or flaired trailing end portion. The saddle surface is generally flat and fashioned with downwardly contoured side panels and the front and rear ends thereof include a downwardly projecting tip and an anchor respectively. A tubular frame underlies and supports the saddle between the tip and anchor in a posture above a bicycle saddle post.
Although considerable effort has been directed at improving rider comfort through the development of bicycle seat pads, insufficient attention has been placed upon surface contours. Pressure points are always going to exist where the rider's pelvic structures rest on the saddle surface. Currently, the anterior weight of the rider's pelvis is forced to straddle the central portion of the saddle surface, compressing sensitive neural, vascular, urologic, and genital structures between the pubis and the crest of the saddle. The medical sequelae being recognized- as pudendal neuritis, torsion of the testes, membranous urethritis, and vascular compression. This translates into sexual and urinary dysfunction after prolonged pressure. The posterior weight of the rider currently rests on the wider flaired posterior saddle surface.

Objects of the Invention
The Arrowhead Saddle is designed to articulate with the human pelvis in such a way as to enhance rider comfort and health by creating surface contours that support the anterior pelvic structures and alleviate the current situation where these structures are forced to straddle the crest of the central saddle. More specifically, the goal is to maximize pressure over the ischiopubic rami and superficial perineal space of the pelvis, thereby minimizing pressure on sensitive neural, vascular, and urologic structures which comprise the human genitalia. This purpose is further served by the peculiar arrowhead cutout creating a pressure free zone in which the above structures can rest.
The Drawings
The objects and advantages of the present invention will become apparent from the following detailed description of the Arrowhead Saddle taken in conjunction with the accompanying drawings where:
FIGURE 1 is a top view of a bicycle saddle having a narrow leading end portion; a central arrowhead cutout C and a flaired trailing end portion' the cross hatched line on the surface defines zones A and B of rider contact and the shape of the proposed detachable pad;
FIGURE 2 is a lateral view showing surface contours of the saddle surface. Notable features are surface elevations at 7 and the recessed cutaways 6, which are the wingtips of the arrowhead;
FIGURE 3 is a lateral view taken after a longitudinal cross sectional cut along line 3 -- 3;

FIGURE 4 is a cross sectional view taken along section line 4 — 4 in FIGURE 1 displaying surface contours at the base of the arrowhead, and the mid-section of the saddle surface.
Detailed Description
Returning to FIGURES 1 - 4 there will be seen the general embodiment of the saddle structure and the details which define the invention. In FIGURE 1, the observer's eye will view the top surface of the saddle with two general pressure zones delineated by the dotted lines, labeled A and B. These zones represent areas where the rider's weight bearing structure will interact with the saddle surface. More specifically, zone A, which is actually an elevated hump 7, will articulate with the rider's ischiopubic rami and superficial perineal space. Zone B is where the rider's ischial tuberosity will rest on the saddle surface. These zones A and B thus represent four specific weight bearing zones to enhance rider comfort by weight redistribution. In the central portion of the saddle surface is a large cutout area in the shape of an arrowhead C. The recess 8 corresponds to the tail of the arrowhead.
Transposing this view onto the lateral view, FIGURE 2, one can appreciate some of the landmarks corresponding to the arrowhead. The recess in the lateral contour 6 represents one of the flaired wingtips of the arrowhead cutout C. Behind this depression one can appreciate the bulging contours of the hump structures 7 which form the rear margin of the arrowhead. These humps also correspond with pressure zones A on the top view.
These humps converge towards the midline where their contour again becomes flush with the surface area of pressure zone B, as shown in FIGURE 3. Referring to FIGURE 4, which is a cross section through the rear base of the arrowhead at the wingtips 6, reveals the cross sectional contour of the critical midseetion, further defining surface features referred to above.

Claims
C L A I M S
What I claim, is having designed a bicycle seat having a narrow front portion which broadens from a forward edge rearwardly to a wider rear portion having a rear edge; characterized by a central cutout having an arrowhead shape extending from a leading tip located near the forward edge of the seat to a wider mid-section, approximately halfway between the front and rear edges; said cutout including a trailing edge portion which narrows in a rearward direction from the mid section to a rear tip located intermediate the mid section of the cutout and the rear edge of the seat, and wherein the seat is relatively flat from the forward edge to the mid section of the cutout but which includes an elevated hump structure which borders the trailing edge and rear tip of the cutout and which extends from the mid section to the rear of the seat, whereas the hump structure will provide a rest for the superficial perineal space of the occupant while the cutout provides a receptacle for the external genitalia.
