Abstract

This invention is related to a shielding assembly comprising a cover plate, upper and lower paddle arms, a circular plate, and a back plate for covering an opening in an arm of a recliner chair. The opening provides clearance for a drive tube that moves independently from the arm. The paddle arms are rotatably coupled to the cover plate, wherein rotation is restrained by tension devices. The circular plate is slidably disposed between the paddle arms and the back plate. The back plate is fixedly attached to the cover plate by fasteners that limit rotation of the paddle arms. In operation, if the drive tube moves upward or downward, the circular plate, having a bore circumferentially engaged to the drive shaft, moves therewith vacating a portion of the opening. One of the paddle arms may be deflected by the drive tube movement while another continues to overlie the vacated portion.
