Abstract
This seat includes a guard-rail able to occupy a lowered first extreme position and a raised second extreme position, and means for locking the guard rail when it is in a lowered position. The locking means include a bistable electromagnet provided with a rod that is able to move between a stable first position in which the rod allows the guard rail to lock in the lowered position by interposing an obstacle in the upward path described by a guard rail element to pass from the lowered position to the raised position, and a stable second position in which the rod allows the guard rail to unlock so that it can be moved into the raised position by moving the obstacle away from the upward path described by the guard rail element.
