Abstract
A bicycle seat is provided including a pair of uppwardly divergent, opposite side support arms having lower ends pivotally mounted from a bicycle frame appreciably below the usual bicycle seat mounting structure of the bicycle frame and upper ends swingable toward and away from each other. The upper ends of the support arms include generally horizontal weight support members having longitudinal mid-portions pivotally supported from the arm upper ends for oscillation about generally horizontal transverse axes and the arms, including their pivotal mounting, are mounted from the bicycle frame for limited oscillation about an upstanding axis, angular displacement about the upstanding axis, in both directions from a center position thereof, being progressively yieldingly resisted.
Claims13
In combination, a bicycle frame having front and rear portions and an upright frame member whose lower end is disposed closely forward of a rear wheel journalled from said rear portion of said frame, a seat structure including mount structure on an upper portion of said upright frame member, a pair of upwardly divergent opposite side arms having upper and lower ends, mounting means mounting said lower ends from said mount structure for limited swinging of said upper ends toward and away from each other on opposite lateral sides of said frame, said upper ends each include rider weight support structure supported therefrom, said mounting means including pivot structure mounting said mount structure from said upright frame member for limited oscillation about said upright frame member.
The combination 7 including spring means operably connected between said arms and said frame yieldingly biasing said arm upper ends toward each other from their limit positions of maximum relative spacing, said links being upwardly convergent, said spring means including at least one elongated, upstanding and compression spring equipped airplane-type shock absorber connected between said frame and guide member.
In combination, a bicycle frame having front and rear portions and an upright frame member whose lower end is disposed closely forward of a rear wheel journalled from said rear portion of said frame, a seat structure including mount structure on an upper portion of said upright frame member, a pair of upwardly divergent opposite side arms having upper and lower ends, mounting means mounting said lower ends from said mount structure for limited swinging of said upper ends toward and away from each other on opposite lateral sides of said frame, said upper ends each include rider weight support structure supported therefrom, at least one flexible rider weight supporting panel extending between said rider weight support structures, said mounting structure being mounted from said upright frame member for limited oscillation about said upright frame member.
