摘要

The handlebars have a bar holder and a fork bridge, connected via an adjustable support. The support is a four-bar coupling linkage (3a,3b,4,7) with associated adjusting device. The linkage consists of fixed holder (7) connected to the fork bridge (1), two coupling members (3a,b) linked to the fixed holder, and the bar holder (4) connected to the members. The adjusting device is a self-locking threaded spindle (5) with motor drive supported on holder and one coupling member. The bearings (9) of the linkage are lined with a vibration-damping material.
