Abstract:
A motor vehicle seat, comprising:(a) a backrest foldable between an erected seating position and a folded sleeping position;(b) a seat cushion movable between a retracted seating position and an extended sleeping position, said seat cushion having opposite front and rear ends and a pair of opposite sides extending between said front and rear ends; and(c) a coupling mechanism mechanically supporting said seat cushion and coupling said seat cushion to said backrest such that folding of said backrest from said erected seating position to said folded sleeping position causes displacement of said seat cushion from said retracted seating position to said extended sleeping position such that in said extended sleeping position said seat cushion is substantially aligned with said backrest in said folded sleeping position, said coupling mechanism including(i) a pair of rigid coupling elements disposed adjacent to said opposite sides and at said rear end of said seat cushion and pivotally mounted at a folding axis extending transverse to said backrest, said coupling elements also mounted at said lower end of said backrest to undergo movement about said folding axis such that movement of said backrest between said erected seating position and said folded sleeping position causes movement of said coupling elements about said folding axis of said backrest and displacement of said seat cushion between said retracted seating position and said extended sleeping position, and(ii) a pair of lever elements disposed adjacent to and fixedly attached at said opposite sides of said seat cushion adjacent to said rear end thereof, said lever elements being respectively pivotally connected to said coupling elements.
