Abstract

A support cushion structure comprises a support cushion panel (1), a base panel (2), and a slidable connection assembly (3) connected between the support cushion panel (1) and the base panel (2). Two sides of the base panel (2) are provided with sliding slots (21), respectively. Multiple positioning blind holes (211) arranged in a longitudinal direction are provided within the sliding slots (21). The slidable connection assembly (3) comprises a base (31) provided with an upper cover (32). Two sides of the base (31) are configured to be vertically movable and position-limited within the sliding slots (21). At least one support cushion fastening plate (33) that can be connected and fastened to a back side of the support cushion panel (1) protrudes and extends from the base (31). A pull handle (34) is provided in the upper cover (32), and an inner end of the pull handle (34) is connected to a pin (35). The pin (35) passes through the base (31) and is positioned in one of the positioning blind holes (211). Pulling the pull handle (34) outward drives the pin (35) to be extracted from the positioning blind hole (211), and allows the pin to slide to another one of the positioning blind holes (211) to be positioned. The invention uses modular assembly to achieve convenient installation, and enables, by simply pulling the pull handle (34), the height of the support cushion panel (1) to be adjusted without requiring users to leave their seats.
