ABSTRACT:
A pillow and bedding retainer for a made-up tip-up bed (11) includes a flexible concave panel (21) extending across a bed storage recess (14). The panel is freely mounted in a parallel spaced pair of horizontal open channels (22, 23) attached to a pivot frame (9) forming a bedding cavity (40). As bed (11) is tilted from a horizontal position (A) to a vertical position (C) through an intermediate position (B) the upper edge (24) of the head of a mattress (13) slidingly engages and presses the panel rearwardly further into the storage recess and tensions the pillow and upper bedding portions against the mattress head top surface retaining them in a diminishing volume of the cavity. The center of curvature of the panel is displaced from the pivot axis (30) of the bed and the panel has a radius of curvature greater than the radius of curvature of the bed pivot axis.
