  • the lock in accordance with FIG. 4 makes it possible to obtain a disengagement making the action of the assistance motor means cease, which avoids damage that is difficult to repair.
  • the pin 40 crosses the angular range corresponding to the flange 49.
  • the forces developed are greater than the triggering threshold of the declutching pin 40 and its spring 41 so that the head 43 will come out of the recess 45.
  • the end 50 can no longer act on the rim 49, assistance continues and the bolt 1 a continues to be driven in rotation by the pawl 20, while the arm 46 and the keeper 2 are stopped.
  • the torque is transmitted from the bolt 1 has the arm 46 by said boss 36. A closing force is therefore transmitted by arm 46 to the latch 2.
  • the assembly is preferably arranged, in particular as regards the force of the spring 41 and the inclination of the faces 45, so that the disengagement occurs for a force, at the level of the keeper 2, of approximately 10 daN, while the closing force, at the end of closing, is of the order of 50 daN.
  • the declutching range 52 corresponds substantially to the first half of the closing stroke, while the range 53 corresponds to the second half.
  • range 54 corresponds for example to 5 mm, while range 52 corresponds to 10 mm and range 53 also to 10 mm.
  • a lock according to the invention is of a simple and robust embodiment, in a small space due to the housing of the freewheel in the bolt. It is clear that other types of freewheel than that described in the particular embodiment may be suitable.
  • Such a lock is applicable to any system for closing a motor vehicle door, side doors, trunk door, tailgate. Protection in the event of an obstacle during closing can be provided in a simple and space-saving manner.
