Definitions

• the invention relates to devices which are responsible for locking / unlocking the rotation of the folding backs of certain motor vehicle seats.
• Some motor vehicles are equipped with a seat provided with a seat (or bench) to receive several passengers and two neighboring folders, foldable independently and frame.
• the relative dimensions of the backs of this type of seat can be 1 / 3-2 / 3 or 60% -40% or 1 / 2-1 / 2, for example.
• These folding folders are intended to allow modularity of the storage space of a motor vehicle.
• Each file is generally associated with a locking / unlocking device which is responsible for securing it to an element of its vehicle, such as the rear shelf cross member, to prevent it from being rotated forwards. or to separate it from this element in order to allow it to be rotated forward and thus folded against the upper face of the seat.
• a locking / unlocking device which is responsible for securing it to an element of its vehicle, such as the rear shelf cross member, to prevent it from being rotated forwards. or to separate it from this element in order to allow it to be rotated forward and thus folded against the upper face of the seat.
