Linkage for adjusting vehicle seat heights and tilt - consists of link pin with bearing section and annular attachment

摘要

The linkage for mounting levers, rocker-arms etc. especially for adjusting the height and tilt of seats, in vehicles for example, has a link-pin (14) fixed to a holder. The bearing section (15) of the link pin (14) has an annular attachment (19) in the form of an outward-widening truncated cone shape increasing in diameter. The plastic bearing bushing (18) enclosing the bearing section (15) is slightly shorter than the bearing section (15). The largest-diameter part of the annular fitment (19) is next to the link-pin (14) head (17) forming a contact surface. ADVANTAGE - The bearing pin's bearing section is designed to reduce clearance and rattling.
