Patent ID: 10512330

Abstract:
A legrest mechanism including a seat base rail, a mechanism rail, a drive assembly, a pivot plate link, a pivot plate, a main drive link, and a parallelogram legrest link assembly. The drive assembly moves the mechanism rail relative to the seat base rail, which drives movement of the parallelogram legrest link assembly between a retracted position and an extended position. The parallelogram legrest link assembly includes first and second legrest links, footrest and legrest drive arms, and a legrest bracket. The main drive link has a pin that is slidingly received in a slot in one of the first legrest link, second legrest link, or main drive link such that movement of the parallelogram legrest link assembly is decoupled from movement of the main drive link when the legrest and/or parallelogram legrest link assembly encounters an obstruction while moving from the extended position to the retracted position.
