1. In a safety device for vehicular electrical openers having an electrical motor with an electrical supply circuit, said electrical motor controlled by a switch forming part of said electrical supply for said motor, a movable member driven by a cable, a kinematic chain for driving said cable, and electromechanical coupling and load-detecting means for coupling and detecting a load between a driving element of said kinematic chain and a driven element of said kinematic chain, said driven element fixed to said movable member, said coupling and detecting means effective to automatically uncouple said driving and driven elements from each other in the event said load exceeds a predetermined value, the improvement comprising:

  • a driving slide fixedly attached to said cable, a driven slide fixedly attached to said movable member, said electromechanical coupling and load-detecting means provided between said driving slide and said driven slide and being arranged so as to automatically uncouple said driving slide and said driven slide from each other in the event said load exceeds said predetermined value.
