Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle accessories, in particular to a motorcycle rear rack with a backrest. Background Art

[0002] For safety reasons, motorcycles are equipped with a rear backrest, mainly for the rider at the back. When starting or riding, the rider has something to lean on, so that they can sit more comfortably and steadily. It is a safety protection measure for riding, which increases the safety factor. At the same time, it can also support the waist during riding, which can increase the riding comfort and effectively relieve the fatigue caused by long-term riding. Therefore, it is very necessary to install a backrest on motorcycles.

[0003] According to the publication number: CN220884632U, a motorcycle rear rack with a backrest is disclosed. This technology discloses "a motorcycle rear rack with a backrest, belonging to the technical field of motorcycle backrests, a motorcycle rear rack with a backrest, comprising: a motorcycle base bracket, a rear backrest mounting assembly provided at the upper end of the motorcycle base bracket, and an adjustment assembly provided at the upper end of the rear backrest mounting assembly." The technical effects include "the backrest hinged by an L-shaped connecting rod can be adaptively adjusted up and down when the rider's back rests on it, thereby better fitting the rider's waist."

[0004] Although the backrest in the above solution can be adjusted to support the passenger's back, when the backrest is not in use, it cannot be conveniently stored, resulting in occupying the space of the rear shelf and limiting the cargo carrying capacity of the rear shelf.
