Abstract:
1. A spring damper system for bicycles having: a first load-applying segment and a second load-applying segment; at least one spring mechanism comprising at least one spring arranged to be operatively effective between said first and the second load-applying segments; a damping means arranged to be operatively effective between the first and said second load-applying segments; a regulating mechanism by means of which the damping behavior of said damping means can be adjusted; whereby said regulating mechanism automatically effects a damping behavior setting of said damping means contingent upon a tension or load present in said at least one spring; whereby the regulating mechanism comprises at least one control element configured as a control rod and arranged to be moveable relative to at least one passage opening by means of which an opening cross-section of said at least one passage opening can automatically be modified for adjusting the damping behavior setting; whereby said at least one spring includes at least one chamber filled only with gas, whereby said at least one chamber filled only with gas acts as a gas spring in concert with the gas present therewithin; whereby said control rod comprises a control rod piston area which is loaded by said gas spring such that the spring force of said gas spring upon loading induces an axial displacement of the control rod; and whereby at least one control rod spring acts on said control rod, a spring force of said at least one control rod spring acting counter to the spring force of said gas spring.
