Definitions

• the present invention relates to the locking devices of the safety belt bolts.
• locking devices comprising two striker bodies adapted to receive safety belt bolts, the device being arranged for example in the rear seat of a motor vehicle.
• FIG 1 is a perspective view of a rear seat 1 of a motor vehicle with three safety belts 5, 6 and 7 adapted to cooperate with locking devices.
• Each of the locking devices of the seat belts is provided with at least one striker body 81 to 84 adapted to receive latches 50, 60, 61 and 70 respectively belts 5, 6 and 7 of safety.
• the rear seat 1 comprises a seat 2 which is fixed permanently, or mounted foldable against the back of the front seat, on the floor 3 of a motor vehicle in a manner known to those skilled in the art.
• the rear seat 1 also comprises a backrest 4 which is fixed permanently on the walls of a trunk, or mounted pivotally on the walls of the trunk or on the seat 2.
• the seat 2 has three seats 9 to 10 able to accommodate three passengers.
• the two lateral places are referenced by 9, the central square is referenced by 10.
• the straps of the lateral safety belts 5 and 7 are fixed by their ends respectively to the frame of the backrest and to the seat frame and comprise for example the two bolts 50 and 70 respectively.
• the bolt 50 is adapted to cooperate with the striker body 81 and the bolt 70 with the body 84.
• the ends of the straps can also be fixed to the body structure or the floor structure.
• the strap of the central safety belt 6 is fixed at one end to the backrest frame and comprises for example two bolts 60 and 61.
• the bolts 60 and 61 cooperate with the striker bodies 83 and 82 respectively.
• the striker bodies 82 and 83 are distributed on either side of the central square 10 to put in position the central belt 6 and to retain the central passenger.
• Figure 1 shows that the striker bodies 81 to 84 are arranged substantially side by side along a longitudinal axis A relative to the seat and which is perpendicular to a receiving axis of the bolts in the striker body.
• the longitudinal axis A corresponds to a transverse axis of the vehicle as a whole.
• the point of attachment of a striker body is then either too far forward or too far back along the axis A depending on the number of passengers on the seat or their build.
• This longitudinal misalignment risks degrading the quality of the restraint of at least one of the passengers, and consequently the safety of said passenger.
• the striker bodies occupy a significant position that affects the comfort of the passengers, both on the side seats 9 and the central square 10. The passengers are generally partially seated on the striker bodies 81 to 84 when the three places 9 to 10 are occupied.
• the invention proposes to overcome at least one of these disadvantages.
• the invention proposes a device comprising two striker bodies adapted to receive safety belt bolts, a first striker body being retractable relative to a second striker body, characterized in that it comprises means movable to automatically move the second body of striker during the retraction of the first strike body.
• the displacement means are able to move the second striker body from a first stable position to a second stable position in which it substantially takes a first position of the first striker body before its retraction;
• - Retraction means for moving the first striker body from a first stable position to a second retracted stable position;
• - Retaining means are adapted to retain the keeper bodies relative to each other a first stable position
• the retaining means further comprise means able to automatically move the first striker body from its second retracted position to its first position when the second striker body is moved from its second position to its first position;
• the striker bodies are, in their first position, arranged substantially side by side along a longitudinal axis perpendicular to a bolt receiving axis;
• the retraction means allow the first striker body to move in a plane perpendicular to a longitudinal axis perpendicular to a bolt receiving axis;
• the second striker body is movably mounted in translation on a rod whose extension axis is parallel to a longitudinal axis perpendicular to a bolt receiving axis;
• the retaining means comprise a lug fixed to a lug for fixing the first keeper body to the retraction means;
• a protection part of the displacement means is fixed to the second keeper body.
• the invention has many advantages.
• At least one of the striker bodies can be retracted under the seat back to make it inaccessible for locking the belt.
• the other body of strike is automatically positioned at a locking position corresponding to a good retention of the seat belt side.
• This retracted position also corresponds to a better accessibility of the striker body for locking the bolt of the belt for the side seat.
• this position corresponds to an area where the average passenger is not sitting on the striker body, which also improves its comfort.
• the two strike bodies are placed side by side.
• the striker body of the side seat is then no longer retracted under the seat back.
• This position is at the expense of a little comfort of the passengers, they can possibly be partially seated on the body of waste.

• the movement of the second striker body 82 from its first position to its second position is a translation parallel to the longitudinal axis A.
• the striker bodies 81 and 82 are respectively mounted on a bracket 811 and 821.
• the shape and length of the fastening tabs 81 1 and 821 depend on the motor vehicle on which the device is intended to be mounted. Note however that the tabs 811 and 821 are preferably of bent shape.
• the tab 81 1 further allows the first keeper body 81 to be further away from the floor 3 than the second keeper body 82, in order to facilitate the locking of a bolt corresponding to a lateral belt on the first striker body 81 and facilitating the locking of a bolt of a central belt on the second striker body 82.
• the fixing lug 81 1 has at its end opposite to the striker body 81 a plate 812 rotatably mounted on the fin 32 of the support 30. The rotation of the lug 81 1 takes place around a rod 34, the plate 812 being held against the fin 32 by means of a head 35.

• a lug 813 is attached to the plate 812.
• the lug 813 may be integral on the plate 812 or be attached to said plate.
• the lug 813 extends perpendicularly to the plate 812, to the lug 821 of the second striker body 82.

• the length of the lug 813 is such that the keeper bodies 81 and 82 of the device are held in their first position of use, corresponding to the Figure 5B and Figure 3A. We will now describe the transition of the bodies 81 and 82 from their first position to their second position.
• the first striker body 81 When a user biases the first striker body 81 according to the arrow 201 shown in FIG. 3B, the first striker body 81 then moves into its retracted position by rotation and begins to enter the location 40 visible in FIG. 5B.

If from the position of FIG. 3C, the second striker body 82 is urged against the spring means 38 in a direction opposite to the arrow 202 of FIG. 3B, when the leg 812 has finished moving along the side wall of the pin 813, the spring means 37 will urge the first striker body 81 in a direction opposite to that represented by the arrow 201. The two striker bodies 81 and 82 are then automatically found in their first position shown in Figure 3A, the end of the pin 813 then coming into abutment against the tab 821.

• the piece of fabric 101 is fixed on the one hand to the upper part of the striker body 82 and on the other hand to the upper part of the housing 100, so that when the second striker body 82 is in its second position, the housing 100 is covered by the piece of fabric 101.
• the piece of fabric is folded between the striker body 82 and the inner walls of the housing 100. This improves the aesthetic qualities. of the seat when the striker bodies are in their second position.
• the part 101 prevents an object from being placed in the housing 100 when the second 82 keeper body is in its second position, which would hinder the operation of the device.
• a passenger for example a child, is also prevented from pinching his fingers in the spring means 38.
• the keeper body 81 When the keeper body 81 is in the retracted position, it can be partially or completely hidden by the base of the seat back, thus prohibiting its use.
