Description

The present invention relates generally to the locking of a movable part to a fixed part on board a vehicle.

A motor vehicle normally includes a glove box with a receptacle having an opening and a flap for closing the opening. The flap is locked in relation to the container by means of a bolt which can be moved via an operating element. A return element brings the bolt back into its locking position of the flap. This return member is normally a helical metal spring.

The locking system may include a foam block positioned alongside the coil spring, provided to prevent noise and vibration generated by the coil spring when it is actuated.

There is also a stop made of elastomer, e.g. B. EPDM (ethylene propylene diene monomer). It makes it possible to dampen the movement of the bolt when it returns to the locked position due to the force exerted by the return member.

The locking system thus comprises a significant number of parts. Because of this, it is complex and involves significant manufacturing costs. Assembly is also complex, with multiple parts having to be assembled on board the vehicle.

In this context, the object of the invention is to propose a locking system of a moving part on a fixed part of a vehicle that is simpler in construction.

Thus, it is the return member itself that provides the damping function when the bolt returns to its initial position due to the force exerted by the return member. This simplifies the design of the locking system.

The locking system includes a smaller number of elements and its manufacturing cost is lower.

Installation on board the vehicle is also easier.

Other characteristics and advantages of the invention will appear from the following detailed description, given by way of indication and in no way limiting, with reference to the attached figures, including:

• is 1 a simplified schematic representation of a vehicle equipped with a glove box;
• is 2 a simplified schematic representation of the glove compartment of FIG 1 ;
• is 3 a perspective view of a part of the glove box of FIG 2 12 showing the latch of the invention;

• is 5 a view similar to that of 4 when the return member is deformed, ie when the bolt is in its release position.

This in 1 vehicle shown schematically is normally a motor vehicle, e.g. B. a passenger car, a truck, a bus, etc.

Alternatively, this vehicle is a train, airplane, or other suitable vehicle.

The motor vehicle 1 comprises a fixed part 3, a part 5 movable with respect to the fixed part 3, and a locking system 7 of the movable part 5 on the fixed part 3.

The fixed part 3 is z. B. the container of a glove box, as in 1 is illustrated schematically.

This container has an opening 9 through which a user can put objects inside the container 3 or remove them ( 2 ).

In this case, the movable part 5 is normally a flap which closes the opening 9.

The movable part 5 is connected to the fixed part 3 via a linkage 11 configured to allow the movable part 5 to be slidable between a position in which it closes the opening 9 and a position in which it uncovers the opening 9 is ( 1 ).

The connection 11 is, for example, a swivel connection.

In another variant, the fixed part is not the compartment of a glove box, but another compartment in the vehicle. the mobile part in this case being a flap allowing to close or unblock an opening of access to the receptacle.

According to another variant, the moving part is not a flap. The moving part is z. B. a screen, or a submersible structure, or any other suitable part.

In this case, the fixed part is a structural element of the interior of the vehicle.

• - ein Bedienorgan 13;
• - einen Riegel 15, der eine Verriegelungsposition, in der das bewegliche Teil 5 in seiner Position in Bezug auf das feststehende Teil 3 verriegelt ist, und eine Freigabeposition, in der das bewegliche Teil 5 in Bezug auf das feststehende Teil 3 verschiebbar ist, aufweist;
• - eine kinematische Kette 17, die die Verschiebung des oder jedes Riegels 15 in eine von der Verriegelungspositionen oder der Freigabeposition ermöglicht;

Normalerweise umfasst das Verriegelungssystem 7 ein Bedienorgan 13.like it in 2 and partly in 3 As illustrated, the locking system 7 includes:

• - an operating member 13;
• - a latch 15 having a locking position in which the mobile part 5 is locked in position with respect to the fixed part 3, and a release position in which the movable part 5 is slidable with respect to fixed part 3;
• a kinematic chain 17 allowing the or each latch 15 to be displaced into one of the locked or unlocked positions;

Normally, the locking system 7 comprises an operating element 13.

The kinematic chain 17 transmits a displacement of the operating member 13 to the bolt 15, the displacement of the operating member 13 driving the bolt 15 to one of the locking position or the release position.

In the example shown, the locking system 7 is mounted on the moving part 5 .

As a variant, the locking system 7 is mounted on the mobile part 3.

The operating member 13 is slidable with respect to the moving part 5 .

For example, it is provided to be manually moved by an occupant of the vehicle. It is mounted on an outer surface of the moving part.

The control member 13 is in this case a lever rotatable with respect to the mobile part 5, or a button rotatable with respect to the mobile part 5, or any other type of control organ.

Alternatively, the control element 13 is moved by an electric motor.

In the example shown, the locking system 7 comprises two latches 15 located transversally on two opposite sides of the moving part 5 . The kinematic chain 17 transmits the displacement of the control element 13 to the two bolts 15.

Alternatively, the locking system 7 comprises a single bolt 15.

The fixed part 3 comprises a receptacle 19 for the or each bolt 15, in which the bolt 15 engages in the locking position. The kinematic chain 17 moves the or each bolt 15 with respect to the moving part 5 in the example shown.

This shift is essentially transverse here.

For example, the kinematic chain 17 comprises an arm 21 for the or each bolt 15, the bolt 15 forming one end of the arm 21.

The arm 21 is oriented substantially transversely.

The kinematic chain 17 also includes a rotating element 23 which is set in rotation by the operating element 13 .

The rotary member 23 is mounted on the inner surface 24 of the mobile part 5 and is connected to the end of the arm 21 opposite the bolt 15. The connection between the rotary member 23 and the arm 21 is configured so that the rotation of the member 23 with respect to the mobile part 5 causes a displacement of the arm 21 with respect to the mobile part 5 substantially transversely in the direction of extracting the bolt 15 from the Recording 19 causes.

The connection can be any type of connection: connection by cam and counter-cam, by an eccentric, by a gear cooperating with a rack, etc.

Thus, the displacement of the operating member 13 drives the or each bolt 15 in its release position.

For the or each bolt 15, the locking system 7 also includes a retrieval element 25, which brings the bolt 15 back into its locking position.

The return organs are all the same.

As can be seen in the figures, the or each return member 25 has a first point 27 fixed to the moving part 5 . The return member 25 also has a second point 29 fixed to an element of the kinematic chain 17.

In the example shown, the first point 27 is fixed to the inner surface 24 of the moving part 5 .

The second point 29 is attached to the arm 21 .

The return member 25 also includes an elastically deformable portion 31 connecting the first point 27 to the second point 29 .

The element of the kinematic chain 17, to which the second point 29 is attached, carries except the one stop 35, which in 3 until 5 you can see.

The return member 25 comprises at least one damping area 37 made of a deformable material which bears against the stop 35 when the bolt 15 is in its locking position ( 3 and 4 ), the cushioning portion 37 being spaced from the stop 35 when the latch 15 is in the release position (see 5 ).

In the example shown, the at least one damping zone comprises two damping zones 37, 39 made of a deformable material, which clamp the stop 35 between them when the bolt 15 is in its locking position.

The cushioning area 37 is spaced from the stop 35 when the latch 15 is in its release position ( 5 ).

The damping area 39, on the other hand, is constantly in contact with the stop 35.

like it in 3 As can be seen, stop 35 is a transverse rib formed on arm 21 .

Advantageously, the deformable portion 31 of the return member has a closed contour. It extends in a plane containing the transverse direction.

The stop 35 is housed inside the deformable portion 31 with a closed contour.

In 4 1 shows the shape of the closed contour deformable portion 31 when the bolt 15 is in its locking position, ie at rest. The closed contour deformable portion 31 has a geometric center C . It can be seen that the two damping areas 37, 39 are located at opposite points of the deformable portion 31 with respect to the geometric center C.

The two damping areas 37, 39 are aligned along the direction D of displacement of the second point 29 with respect to the first point 27 when the bolt 15 passes from its locked position to its released position and vice versa.

This displacement direction D is essentially transverse in the example shown.

The first point 27 is a block that is connected to the damping area 37 via a material bridge 41 . like it in 3 As can be seen, the bridge of material 41 engages in a recessed relief 43 formed in a rib 45 formed on the mobile 5 or fixed part. The rib 45 extends in a plane substantially perpendicular to the displacement direction D and is engaged between the first attachment point 27 and the deformable portion 31 .

The second point 29 is also a block that is connected to the damping area 39 via a material bridge 43 . The block forming the second point 29 is housed in an opening 49 in a rib 51 formed on the arm 21. FIG. The block is rigidly attached to the rib 51 by any suitable means.

The deformable material constituting the cushioning areas 37 and 39 is selected from the following list: EPDM, natural rubber (NR), polyisoprenoids, synthetic rubbers such as styrene butadiene (BSR) or hydrogenated nitriles (HNBR) or fluoroelastomer (FKM), silicone .

Preferably, the entire deformable portion 31 is made of the deformable material. Advantageously, the return member 25 is made entirely of deformable material. The functioning of the locking system 7 will now be described in detail.

in the in 2 and 3 position shown is the or each bolt 15 in its locking position.

It is engaged in the corresponding seat 19.

It is brought back into this locked position by the corresponding return element 25 .

In this situation, the return element 25 has the in 3 and 4 shown shape. In particular, the two damping areas 37 and 39 are in contact at the stop 35.

The movable part 5 is then locked in position with respect to the fixed part 3 .

In order to move the moving part 5 with respect to the fixed part 3, a user moves the operating member 13 or activates an automatic control.

The kinematic chain 17 transmits the movement of the control element 13 to the or each bolt 15.

The kinematic chain 17 moves the or each bolt 15 from the locked position to the released position.

More precisely, the movement of the control member 13 causes the rotating part 23 to rotate, thereby moving the or each lever 21 transversely.

Due to the displacement of the arm 21, the bolt 15 is displaced out of the receptacle 19.

By moving the arm 21, the second point 29 in the 4 shown displacement direction D in relation to the first point 27 shifted. It is shifted in the direction of a spread, ie the distance between points 27 and 29 is increased along the direction of shift D.

As a result, the deformable section 31 deforms by stretching along the displacement direction D.

In the example shown, in the rest state, ie in the locking position of the bolt 15, the deformable portion 31 has a so-called race track shape, which is stretched perpendicularly to the displacement direction D. When the latch 15 is in its release position, the deformable portion 31 has the shape of a television screen stretched along the direction of displacement D, as shown in FIG 5 you can see.

Due to the displacement of the second point 29, the damping area 37 is moved away from the stop 35. On the contrary, the cushioning portion 39 remains in contact with the stop 35, due to the fact that this stop is formed on the arm 21 and is displaced together with the arm 21.

The user can then slide the movable part 5 in relation to the fixed part 3, e.g. B. open the glove compartment of the vehicle by sliding the flap.

When the user releases the control element 13 , the kinematic chain 17 no longer exerts a pretension in order to space the second attachment point 29 from the first attachment point 27 . The return member 25 forces the bolt 15 into its locked position.

To do this, the deformable portion 31 of the retractor, which has a shape memory, returns to its original shape, which is shown in 4 is shown. This tends to bring the first and second attachment points 27, 29 closer together. More specifically, the first attachment point 27 is located on the rib 45 and can be different in the representation of FIG 3 do not move to the right along the displacement direction D. As a result, it is the second attachment point 29 that is shifted in the direction of the first attachment point 27 and takes the arm 21 with it. The movement is interrupted when the stopper 35 comes into contact with the cushioning area 37 .

The bolt 15 then reaches its locking position.

Because the cushioning portion 37 is made of a deformable material, the impact of the stopper 35 on the cushioning portion is silent.

Since the areas of the return member 25 that are in contact with the stop 35, i. H. moreover, since the damping areas 37 and 39 are made of deformable materials, the vibrations and relative movements of the return member 25 with respect to the stop 35 do not cause any disturbing noises or vibrations.

The invention can have a large number of variants, some of which are described below.

The kinematic chain is alternatively different than that described above. It can include various deflection elements between the control element and the bolt. For example, the one-piece arm 21 can be replaced by several arms connected by connecting rods or deflections. In this case, the second attachment point is connected to one of the arms or to the connecting rod or to another suitable element of the kinematic chain.

The stop 35 is not necessarily formed on the element of the kinematic chain to which the second attachment point 29 is connected. Alternatively, the stop 35 is carried by the movable part 5. In this case it is the cushioning area 39 which is spaced from the stop 35 when the bolt 15 is in its release position.

According to another variant, the return member 25 has only a single damping zone in contact with the stop 35 when the bolt is in the locked position. In the embodiment in FIG 3 with a stop 35 carried by the element of the kinematic chain to which the second attachment point 29 is attached, only the damping area 37 would be in contact with the stop 35. Area 39 would be permanently spaced from stop 35 . When the stop 35 is formed on the movable part 5, the area 37 is permanently spaced from the stop 35 and the cushioning area 39 comes into contact with the stop 35 in the locking position of the bolt.

In another alternative embodiment, the kinematic chain 17 moves the bolt 15 from the released position to the locked position and the return member 25 returns the bolt to its released position. The cushioning area is in contact with the release position of the latch and is spaced from the stop in the latched position.

According to another variant, the locking system 7 is mounted on the fixed part 3 and not on the moving part 5. In this case, the bolt 15 moves with respect to the fixed part 3 between its locked position and its released position. The control element 13 is then normally mounted on the fixed part 3. The stop 35 is formed either on the fixed part 3 or on the element of the kinematic chain 17 to which the second attachment point 29 is connected. The first attachment point 27 is connected to the fixed part. In this embodiment, the seat 19 is carried by the movable part.

The deformable section 31 of the return member does not necessarily have to have a closed contour. For example, this section alternatively has a U-shape that is open at the bottom or at the top.

The return member 25 need not necessarily be made entirely of deformable material. For example, only the deformable portion 31 is made of the deformable material, while the first and second attachment points 27, 29 are made of a rigid material.

The different variants described above can be implemented individually or in combination with one another.

The invention presents numerous advantages.

If the return member has two damping zones which are in contact with the stop when the bolt is in the locked position or in the released position, the position of the bolt is particularly stable. Disturbing noises caused by possible vibrations are reduced to a minimum.

If the entire deformable section is made of the deformable material, the manufacture of the deformable section is particularly simple.

If the return member is made entirely of deformable material, this return member is particularly easy to manufacture.

When the deformable material is selected from the following list - EPDM, natural rubber (NR) referred to as polyisoprenoids, synthetic rubbers such as e.g. B. styrene butadiene (BSR) or hydrogenated nitrile (HNBK) or fluoroelastomer (FKM), silicone - the damping of the movement of the bolt is achieved particularly effectively, and annoying noises are reduced to a particularly low level.

When the deformable portion of the return member has a closed contour, the transmission of forces in the deformable portion is balanced and the deformation of the return member is uniform. The contacting of the cushioning zone(s) with the stop is easier to control.

The fact that the two damping areas are located at opposite points of the deformable portion with respect to the geometric center also contributes to allowing satisfactory control over the contacting of the damping zone(s) with the stop.

The invention is particularly well suited in the event that the fixed part is a container with an opening and the movable part is a flap for closing the opening.

The invention is particularly easy to adapt to the case where the kinematic chain comprises an arm, one end of which defines the bolt, the first point of the return member being fixed to the flap, while the second point of the return member is fixed to the arm.
