HIGH-STRENGTH CONTINUOUS SEAT ECCENTRIC BACKREST ADJUSTER

WIPO Patent Application WO/2024/017138

A1

The present invention relates to a high-strength continuous seat eccentric backrest adjuster, which comprises a gear toothed plate and a ring gear toothed plate which can rotate relative to each other, the gear toothed plate and the ring gear toothed plate being connected to each other by means of mutually meshed teeth; and an eccentric part driven by a cam, the eccentric part rotating in the circumferential direction to drive relative rolling motion between the gear toothed plate and the ring gear toothed plate. The ring gear toothed plate is provided with a first axis point, the gear toothed plate is provided with a second axis point, the eccentric distance e of the ring gear toothed plate relative to the gear toothed plate is the linear distance between the first axis point and the second axis point, and e is 1.35 mm-1.65 mm. According to the high-strength continuous seat eccentric backrest adjuster of the present application, by setting the eccentric distance e of the ring gear toothed plate relative to the gear toothed plate to be 1.35 mm-1.65 mm, the strength of the backrest adjuster is increased, and under the condition that the strength is kept unchanged, the backrest adjuster has a small diameter and light weight, so that lightweighting is achieved.
