Patent ID: 8287022

Claim:
A rear masking device ( 20 ) for a motor vehicle, comprising: supports ( 30 ) intended to be integral with the sides ( 14 ) of the motor vehicle; a shelf ( 32 ) rotatably mounted about a transverse axis (B-Bâ€²) in the supports ( 30 ) between a substantially horizontal position disposed so as to bear on the supports ( 30 ) and an inclined limit of travel position; a mechanism ( 34 ) for articulation of the shelf ( 32 ) relative to the supports ( 30 ) comprising, for each support ( 30 ), at least one abutment surface ( 76 ) delimited by the shelf ( 32 ) and a complementary abutment surface ( 90 ) delimited by the support ( 30 ), the abutment surface ( 76 ) and the complementary abutment surface ( 90 ) being intended to slide on each other during the pivoting of the shelf ( 32 ) about its transverse axis (B-Bâ€²) in order to prevent radial movement of the shelf ( 32 ) in a forward direction with respect to the transverse axis (B-Bâ€²), the abutment surface ( 76 ) and the complementary abutment surface ( 90 ) being located radially at a first distance from the transverse axis (B-Bâ€²), the mechanism ( 34 ) for articulation of the shelf ( 32 ) comprising a retaining surface ( 82 ) integral with the shelf ( 32 ) and a complementary retaining surface ( 96 ) defined by each support ( 30 ), the retaining surface ( 82 ) and the complementary retaining surface ( 96 ) being located radially at a second distance from the transverse axis (B-Bâ€²) which is greater than the first distance, wherein the retaining surface ( 82 ) and the complementary retaining surface ( 96 ) co-operate for each inclined position of the shelf ( 32 ) between its substantially horizontal position and its inclined limit of travel position in order to prevent radial movement of the shelf ( 32 ) towards the rear with respect to the transverse axis (B-Bâ€²), and in the substantially horizontal position, the retaining surface ( 82 ) is disposed away from the complementary retaining surface ( 96 ) in order to permit radial movement of the shelf ( 32 ) towards the rear between a position engaged in each support ( 30 ) and a disengaged position away from the supports ( 30 ).
