Definitions

  • the present invention relates to a locking mechanism which allows positioning the backrest frame of a sleeper seat in at least three positions, i.e. a lying, relaxing or seat, relative to the seat frame of the sleeper seat connected by articulation with it, the mechanism comprising a pawl which can be pivoted relative to the seat frame under the influence of a spring, and being able to penetrate in at least two notches at the end of a profile belonging to the file-frame.
  • Such a mechanism is known and is often used to position the backrest frame of a sleeper seat in three positions.
  • three positions we mean a sitting position in which the backrest frame is vertically or substantially vertically, a relaxed position, i.e. a position between the usual sitting position and the position lying down, and finally a lying position in which the two profiles belonging to the two executives of the furniture and connected to each other by articulation are in mutual extension.
  • the ratchet mounted on the end of the seat frame of the sleeper seat so as to pivot, pivot easily, under the influence of a spring, in corresponding notches provided on the end of the profiles belonging to the file-frame and connected by articulation to the seat frame.
  • a profile change of the profile in which said notches are located is provided beyond said notches, considered in the direction in which the pawl moves by above these notches when the backrest frame is brought to the lying position, which change of profile having the shape of a recess whose depth is sufficient to prevent the pawl from falling still in contact with said profile belonging to frame-folder.
  • Figure 1 is a side view of the mechanism locking in a position in which a blockage may occur.
  • Figure 2 shows, on an enlarged scale by compared to FIG. 1, the position of the parts which cause said blockage.
  • Figure 3 shows the mechanism of locking according to the invention.
  • Figure 4 shows, on an enlarged scale by compared to figure 3, the parts of the mechanism lock according to the invention in which said blockage is prevented.
  • the locking mechanism according to the invention belongs to the types of locking mechanisms in which a profile 1, belonging to the seat frame is articulated at the height of point 2 with a profile 3 belonging to the file frame.
  • a swivel ratchet 4 with point hinge 5 is provided on the end of profile 1.
  • Said pawl has the shape of a square including one end is connected, at point 6, by a spring traction 7 at a point 8 of the same profile 1.
  • the pawl 4 is easy installation in and out of notches 9 and 10 by which position relaxes, respectively position seated, can be established.
  • tip shaped tip of the ratchet 4 is housed most of the time in its correct position.
