Foldable Vehicle Seat With Headrest-to-Pillow Flat-Lay Design

The patent implements a two-stage rotation mechanism for the backrest. The first rotation stage reclines the backrest to a predetermined angle, and the second rotation stage completes the flattening process. This dynamic, multi-stage approach allows the backrest to transition smoothly from an upright position to a fully flat position without creating gaps or stepped portions, thereby achieving both seating flatness and comfort for lying down.

The patent designs the headrest with multi-functionality. It can be mounted on the backrest during normal driving to provide head support, and during camping mode, it can be detached and used as a pillow on the ground or on camping gear. This universal design eliminates the need for separate storage space while preventing interference with facing seats during camping, as the headrest becomes part of the camping equipment rather than a removable component at risk of loss.

The patent merges the headrest with the camping functionality by designing it to serve dual purposes: as a headrest during driving and as a pillow during camping. This integration eliminates the need for separate storage space for the headrest, as it becomes part of the camping equipment. The headrest can be stored within camping gear or used directly on the ground, thereby maximizing the lodging space inside the vehicle while preventing loss.
