Abstract
Abstract A simplified, self-locking cushion assembly, such as a seat or back cushion for a vehicle seat. The cushion assembly incorporates a flexible cover having a flap portion along each of its edges. The flexible cover extends around a resilient cushion filler resting upon a cushion support which is attached to the frame member of the cushion assembly. In assembly, the flexible cover is pulled tightly over the top of the resilient cushion filler, thereby compressing the cushion filler between the flexible cover and the cushion support. A part of the flexible cover flap portion is tucked between the frame member and cushion support. The force created by the tendency of the compressed cushion filler to expand against the cushion support secures the flap portion in that position.
