Definitions

  • the invention relates to a lock for opening a motor vehicle.
  • EP 1 030 014 comprises a catch bolt of a striker subjected to a return spring mounted on the axis of rotation of the bolt, one end of this spring bearing against a bearing surface of the bolt and the other end of the spring coming insert into a fixed part of the lock.
  • This spring working in torsion or in compression ensures the automatic return of the bolt in fully open position, its closure being achieved against the force of this spring, by the thrust of the striker on one of its lever arms, when a slam of the opening, for example.
  • the part, which constitutes the spring, must be stored and mounted during the manufacture of a lock, which entails a cost of management and manufacturing.
  • this spring return arrangement causes a relatively high impact energy and therefore a relatively large noise.
  • the invention solves these problems by proposing a lock for a motor vehicle opening which provides this recall of the bolt, and its holding in the open position without a specific part to mount and with a reduction of noise.
  • the invention provides a lock for a motor vehicle door having in a housing a catch bolt of a striker, rotatable about an axis and subjected to a biasing element to the fully open position.
  • Said bolt and said lock being arranged in such a way that the striker pulls a lever arm from the bolt to an intermediate opening position, during an opening, characterized in that said return element in the fully open position consists of an elastic element having a boss shaped so that the bearing force on the boss is offset from said axis of rotation of the bolt and induces a return of the bolt to the fully open position and in that said intermediate opening position corresponds to a crossing said boss until the boss is able to exert a torque of rotation of the bolt to its fully open position.
  • the invention may further comprise one or more of the following features, taken alone or in combination:
  • the return element is disposed on a portion of the housing and cooperates with an element arranged on the bolt; - The return element is molded into the housing part;
  • the cooperation element is overmolded on the bolt
  • the return element also cooperates with a wedge bolt disposed on the housing part; - The return element is disposed on the bolt and cooperates with a portion of the housing;
  • the return element is overmolded on the bolt.
  • Figure 1 is a longitudinal sectional view of a lock according to the invention, in the closed position.
  • Figure 2 is a longitudinal sectional view of a lock according to the invention according to a first embodiment, in the intermediate open position.
  • Figure 3 is a longitudinal sectional view of a lock according to the invention, in the fully open position.
  • Figure 4 is a perspective view of a housing portion of a lock according to the invention.
  • Figure 5 is a longitudinal sectional view of a lock according to the invention according to a second embodiment, in the intermediate open position.
  • Figure 6 is a longitudinal sectional view of a lock according to the invention according to a third embodiment, in the intermediate position of opening.
  • Figure 7 is a longitudinal sectional view of a lock according to the invention according to a fourth embodiment, in the intermediate open position.
  • a lock for a motor vehicle door comprises in a housing a catch bolt 1 of a keeper 2, rotatable about an axis 3 and subjected to a return element 4 totally open position.
  • the bolt 1 and the keeper 2 are arranged and shaped so that the striker 2 pulls a second lever arm 1B of the bolt and drives the latter in rotation, to an intermediate opening position, corresponding to the loss of contact with the striker and shown in Figure 2, during an opening.
  • the bolt 1 is then driven and then held in the fully open position shown in FIG. 3 by the return element 4.
  • this return element 4 is a resilient element integrated in a plastic housing part 6, close to the bolt and cooperating with a cooperating element 1C arranged on the bolt.
  • the return element can be made by any elastic element integrated in a fixed element of the lock near the bolt.
  • the return element 4 is molded in the housing part 6.
  • the cooperation element 1C is overmolded on the bolt.
  • this return element 4 consists of an elastic tongue comprising a boss 4A and shaped in a recess in the housing part 6 situated in a plane parallel to the front surface of the bolt 1.
  • This boss is preferably formed by a semicircular rounded shape of the tongue 4.
  • the cooperation element 1C carried by the bolt is non-limiting in the form of a pin which extends in a plane perpendicular to the front surface of the bolt 1.
  • This element of cooperation is arranged on the front surface of the second lever arm 1B of the bolt and is introduced between a wall of the hollow of the housing portion 6 and the tongue 4, the side of the boss 4 A.
  • the boss 4A is directed towards the axis of rotation 3 of the bolt 1 and shaped so that the support force of the cooperation element 1C on this boss is shifted below the axis of rotation 3 of the bolt in the intermediate opening position shown in Figure 2 to form a torque to the fully open position shown in Figure 3.
  • the lock is subsequently closed in the conventional manner by pushing the striker against the first lever arm 1A of the bolt and raising the engagement element 1C above the boss 4A towards the upper part of the tongue 4. as shown in Figure 1.
  • the cooperation element 1C carried by the bolt 1 is disposed on the front surface of the first lever arm 1B of the bolt, the elastic tongue 4 being shaped in a suitable hollow of the housing portion 6 located in a plane parallel to the front surface of the bolt 1.
  • the cooperation element 1C is carried by an outgrowth of the bolt 1 opposite to the lever arms 1A and 1B, the elastic tongue 4 being shaped in a suitable hollow of the housing portion 6 located in a plane parallel to the front surface of the bolt 1.
  • the lock also comprises a wedge 7. It is commonly used for an elastically deformable element used to dampen bolt movements. of the invention, the elastic tongue 4 is disposed against the wedge bolt. In this way, the element 1C cooperation in the form of a protrusion disposed on the back of the bolt 1 will push the tongue 4, which will itself compress the hold bolt 7. Moreover, by arranging a recess 8 on the wedge bolt we can better adapt the effort. As soon as the protrusion of bolt 1 has crossed the boss 4A of tongue 4, then the block bolt 1 will restore the energy by pushing the tongue 4 and thus cause the torque on the bolt 1. Thus, the wedge bolt 7 will bring a stability of the function in the time and whatever the temperature.
