VARIABLE GEOMETRY SEAT, IN PARTICULAR FOR MOTOR VEHICLE, WITH ROTARY ANTI-SUBMARINING PROTUBERANCES

摘要

The invention concerns a variable geometry seat, in particular for a motor vehicle, comprising at least a substantially rigid rectangular seating platform (17, 17') covered with a cushion and mounted pivoting on a seat frame (7) between first and second positions wherein, respectively, first and second adjacent edges of the seating platform extend in front of the seat, and wherein at least an anti-submarining protuberance extends along the front edge of said seat. Said seat is characterised in that the anti-submarining protuberance is substantially rectilinear and mounted in rotation relative to the seating platform about an axis substantially perpendicular thereto, so as to be selectively adjustable by rotation along the front edge of the seat.
