Abstract: A trunk lid for a motor vehicle includes an inner lining, a rear window, and a structural reinforcement. The structural reinforcement includes an upper portion which defines a rear-window opening and a lower portion which extends the upper portion toward the bottom of the trunk lid. The structural reinforcement is made in a single piece of a polymer material. An outside of the structural reinforcement is completely covered at least by the rear window and an outer covering panel placed beneath the rear window. An inside of the structural reinforcement is completely covered by the inner lining. The structural reinforcement and the inner lining interact to form a first hollow frame, of a first closed section, surrounding the rear-window opening, and to form a second peripheral hollow frame, of a second closed section, that is close to the outer edges of the trunk lid.

Abstract: The invention relates to a motor vehicle trunk lid (1) that includes: a structural reinforcement (18), an inner lining (42), and a rear window. The structural reinforcement (18) is made up of an upper portion, defining a rear window opening, and a lower portion that extends the upper portion toward the bottom of the trunk lid (1). According to the invention, the structural reinforcement (18) is produced from a single polymer material part. Said structural reinforcement is covered, on the outside thereof, by at least the rear window and by an outer decor panel placed under the rear window so as to completely cover the structural reinforcement (18), and said structural reinforcement is completely covered, on the inside thereof, by the inner lining (42).
