摘要

The backrest angle adjusting system for swing seats is built into the rear suspension bars. These are made up of telescopic tubes (51, 56) with rows of bores. A stop (52) prevents the inner tube from being pulled out of the outer tube. The end of a snap ring (54) inside the inner tube is fitted through one set of bores and is locked in position by a locking band (53).
