Abstract:
A bicycle seat for a bicycle having an overall length (B) and a maximum width (D), comprising:(a) an elongated frontal portion including a frontal support surface for supporting a bicycle rider when the rider is in a racing position with his or her tail bone positioned over said frontal portion, and having means defining an elongated opening with inner surfaces converging toward the front of the seat and positioned to receive the neurovascular bundle in the perineal area of the rider when the rider is in a performance or racing position, said means defining an elongated opening including recessed sloping walls and at least a portion of said elongated opening being a through-hole passing entirely through the seat, said frontal portion having an overall length (G) substantially equal to one-half of the overall length (B) to enable the rider to control the bicycle in performance or racing position;(b) a perforate medial portion integrally connected to said frontal portion and including a medial support surface designed to support the rider when the rider is in a performance position and his or her tail bone is positioned over said medial portion, said medial support surface having means defining an arcuate opening extending coextensively and contiguously from said elongated opening and forming its rearmost terminus, said means defining an arcuate opening including a recessed arcuate sloping wall and at least a portion of said arcuate opening being a through-hole passing entirely through the seat, said arcuate opening being positioned, shaped, and dimensioned to avoid producing pressure on the rider's perineum when the rider is seated on the seat, the rearmost terminus of said arcuate opening being disposed in said medial portion at a distance from the front of the seat equal to about 5/8 of the overall length (B) to position said arcuate opening so that said arcuate opening receives the neurovascular bundle of the rider when the rider is in the touring position, and extending therefrom continuously forwardly to form said elongated opening in said frontal portion, to form a single continuous opening;(c) an imperforate rear portion integrally connected to said medial portion at about the maximal width (D) and extending rearwardly therefrom, said rear portion having a length equal to about one quarter of the overall length (B), said rear portion including a rear support surface for supporting the rider's buttocks when the rider is in a touring position with his or her tail bone positioned over said rear portion, said maximal width (D) being equal to about one-half of the overall length (B);(d) wherein said frontal support surface, said medial support surface, and said rear support surface are generally coplanar and are tapered gradually; and(e) said continuous opening being generally tear-drop shaped and being positioned such that a neurovascular bundle of the rider is positioned over and received by said continuous opening when a rider is in a touring, performance, or racing position, said continuous opening having a width (A) sufficient to receive the entire width of the neurovascular bundle of the rider within said continuous opening when the rider is in the touring, performance, or racing positions and when the seat is compressed under the weight of the rider, said continuous opening being positioned, shaped, and dimensioned consistent with anatomical measurements of the size and location of the neurovascular bundle.
