Suspension for a bicycle saddle

Abstract

A seat apparatus includes a rigid base adapted for selectively mounting on a seat post of a bicycle and includes an armature mount. A rigid armature has a rear end, a front end, and a central mounting portion adapted for fixing with the armature mount of the base. A saddle has a top side, a bottom side, a front end, and a rear end, the top side being adapted for receiving a person thereon in a seated position. A connecting element is fixed between the bottom side of the saddle and with the front end of the armature. A cushion is fixed between the bottom side of the saddle and the rear end of the armature and includes a top membrane, a bottom membrane, and at least one peripheral membrane all capturing a cushioning substance therebetween.

(15) FIGS. 1-3 illustrate a seat apparatus 10 for mounting on a seat post 25 of a bicycle 20 or similar vehicle. A rigid base 30 is adapted for selectively mounting on the seat post 25 of the bicycle 20 and includes an armature mount 40.

(16) A rigid armature 50 has a rear end 58, a front end 52, and a central mounting portion 55 adapted for fixing with the armature mount 40 of the base 30. Preferably the armature 50 includes a pair of rearwardly-projecting rigid arms 59 (FIG. 4), each terminating at the rear end 58 of the armature 50. The base 30 and armature 50 are preferably made from a strong metal material.

(17) A saddle 60 has a top side 69, a bottom side 61, a front end 62, and a rear end 68, the top side 69 being adapted for receiving a person 18 thereon in a seated position. The saddle 60 may be a resilient or flexible material such as leather, foam, cushioned vinyl, or the like.

(18) A connecting element 70 is fixed between the bottom side 61 of the saddle 60 proximate the front end 62 thereof and with the front end 52 of the armature 50. The connecting element 70 has a resilient member 80 for providing a first resilient connection between the saddle 60 and the armature 50. The connecting element 70 preferably further includes a double-hourglass shaped elastomeric spacer 75. In such an embodiment, the front end 52 of the armature 50 is a U-shaped member 51 (FIGS. 2, 4, 6A and 6B) partially curved around the elastomeric spacer 75. A mechanical fastener 100, such as a bolt or pin, is longitudinally aligned with the elastomeric spacer 75. The curved front end 52 of the armature 50 fastens the elastomeric spacer 75 to the front end 62 of the saddle 60.

(19) A cushion 90 is fixed between the bottom side 61 of the saddle 60 proximate the rear end 68 thereof and the rear end 58 of the armature 50. The cushion 90 provides a second resilient connection between the saddle 60 and the armature 50.

(20) Preferably the rear end 58 of the armature 50 includes a rigid lower bed 110 having an upwardly-facing recess 120 (FIG. 2). Similarly, the bottom side 61 of the saddle 60 proximate the ear end 68 thereof includes an upper bed 130 having a downwardly-facing recess 140. The cushion 90 includes a top membrane 98, a bottom membrane 92, and at least one peripheral membrane 95 all capturing a cushioning substance 150 therein, such as foam, gel, elastomeric rubber, a non-compressible fluid material, or the like. As such, the cushion 90 is fixed between the recesses 120,140 of the upper and lower beds 130, 110 such that the rear end 68 of the saddle 60 is able to rotate up and down and shift laterally left and right (FIGS. 8C, 8D) about a pivoting front end 62 thereof. The cushion 90 may be fixed to each recess 120,140 with ultrasonic bonding, an adhesive 160, a mechanical faster 170, or the like. The upper bed 130 and top membrane 98 may be integrally formed, and the lower bed 110 and the bottom membrane 92 may be integrally formed.

(21) In one embodiment, the peripheral membrane 95 includes an inner membrane 94 adapted to contain the cushioning substance 150 therein, and at least one retention cord 180 is threaded between the top and bottom membranes 98,92 outside of the inner membrane 94. As such, the at least one retention cord 180 prevents the inner membrane 94 from exceeding a predetermined diameter and thereby maintaining a minimum height H.sub.m of the cushion 90 when the cushion 90 is under compression (FIGS. 7-8D) between the upper and lower beds 130,110. The at least one peripheral membrane 95 may further including at least one outer membrane 96 adapted to contain a lubricant 190, such as oil, between the top membrane 98, lower membrane 92, inner membrane 94, and the outer membranes 96 (FIG. 5).
