Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a rear-seat automotive seat that folds backward. Background Technology

[0002] The existing folding structure of the rear seats of automobiles usually adopts forward flipping and relies on a complex multi-link mechanism. Although the zero-gravity seats of some high-end models can achieve multiple posture adjustments, the mechanism is complex and there are many parts. This not only increases the production cost significantly, but also makes the assembly difficult, consumes more manpower and resources, and is not convenient for later maintenance.

[0003] At the same time, the existing seats fold forward, resulting in insufficient flatness of the vehicle body, which often occupies a certain amount of space and affects the expansion of storage space such as the trunk. This cannot meet users' needs for larger and flatter storage space, especially for scenarios where there is a need to load large items, where the limitations are more obvious. Utility Model Content
