- the wedge comprises a concave portion 52, 52 ', 52 "intended to come into contact with the pivoting lever 32 in the event of an impact F.
- the outer opening control 30, in particular its lever 32 is brought closer to the inner panel 12. More specifically, the lever 32 has collided with the wedge which prevents the lever from pivoting in the S direction during and / or after this impact.
- the concave portion is toothed and / or notched, as illustrated in Figures 6 to 11.
- the pivoting lever 32 comprises a convex portion 321.
- this convex portion 321 is toothed and / or notched.

- the first curvature 33 and the second curvature 53 may have identical or substantially identical radius values and centers coincident or substantially coincident when the door 10 is not pushed in or impacted.
- the concave portion of the wedge extends over a thickness E by example greater than the thickness of the pivoting lever 32 in the longitudinal or substantially longitudinal direction of the vehicle, as illustrated in FIG. 1.
- the concave shape 52 then extends longitudinally on either side of the lever 32, for example over a distance of about fifteen mm on each side relative to the longitudinal overall overall of the pivoting lever 32.
- the convex portion of the pivoting lever 32 then extends, for example, over this thickness value E or substantially over this value, in the longitudinal or substantially longitudinal direction.
- the convex portion 321 extends over a value less than or greater than this value E.
- the door 10 comprises a window guide 70 that prevents the door from opening in a crash or accident.
- the external opening control 30 placed on the external face is brought closer to the lock 20 during the crushing phase of the door 10. Thanks to the wedge arranged on the window guide 70, this crushing does not lead to untimely and unintentional opening of the lock 20, the external opening control, more precisely its pivoting lever 32, being blocked in pivoting by the wedge. Indeed, the convex portion of the pivoting lever comes into contact with the concave portion of the wedge due to the proximity of the outer panel 1 1 towards the inner panel 12. Thus, even in the case of a transmission system 40 by rod, the lock 20 of the impacted door does not open and the door 10 remains closed following the impact.
- the wedge can transmit this compression to the inner door casing or panel 12.
- the wedge fixed to the window guide can be arranged at the level of the lock and at a small distance in the transverse direction thereof, so that the wedge can come to rest on the lock 20 in the event of an impact.
- the lock being fixed to the inner panel 12, the inner panel 12 then reinforces the outer panel 1 1 and limits the deformation of the outer panel 1 1 upon impact.
- the wedge is arranged with a clearance J in the transverse direction with respect to the lock. The play J is reduced to avoid any inertia.
- the wedge is fixed at least partially on the lock 20 or a part 21 of the lock.
- the lock being fixed on the inner panel 12, the inner panel 12 then reinforces the outer panel 1 1 and limits the deformation of the outer panel 1 1 upon impact.
- the locking means blocks the inadvertent movement of the external opening control 30 by immobilizing its pivoting lever 32 in the event of an impact. Indeed, the pivoting lever 32 comes into contact with the wedge on which the external opening control comes crashing down during the crash.
- the distance D, illustrated in FIG. 8, between the convex portion of the lever and the concave portion of the wedge is between 3 mm and 9 mm, preferably of the order of 6 mm.
- a reconciliation between the external opening control and the lock in the transverse direction, or substantially, of a value at least equal to the value of distance D generates contact between teeth 54, 54 ”and shim 51, 51”.
- the wedge extends over the entire height of the convex portion 321 of the pivoting lever. So if the approximation of the external opening control and the lock takes place without any pivoting of the lever 32, the concave portion of the wedge comes into contact with the convex portion of the lever and stops any subsequent pivoting.
- the convex portion 321 when the external opening control is not requested and the door not impacted, extends above, in the vertical direction, the portion. concave.
- the concave portion of the wedge does not come into contact with the convex portion of the lever, the convex portion then moving at the same time. above the hold. Note that this still results in a blocking of the pivoting of the lever due to a recess 35 provided in the lever abutting against a slope 55 ’formed above the concave portion, as illustrated in Figure 8.
- a pivoting of the pivoting lever causing a downward travel of a linkage fixing point 36 to a level NO generates the opening of the lock and therefore the opening of the door.
- NO level the distance in the vertical direction between the fixing point 36 at rest with the door closed and not impacted, NC level, and the fixing point 36 allowing the door to be opened, NO level, is between 9 mm and 1 1 mm.
- the volume of the wedge 51 is advantageously integrated into a part near the pivoting lever 32, namely the window guide 70 and / or the lock 20.
- the pressure stress applied. on the wedge 51 is preferably reflected, at least partially, on the lock 20.
- the fixings of the window guide, for example example on the inner panel 12, are then not or little stressed during this compression.
- the window guide 70 comprises one, two or even more legs 73 are provided to span the lock 20.
- the legs 73 allow the lock to be stepped over because it is preferable not to attach to the lock.
- the lock is a standard part for various types of vehicles.
- the window guide is a part specific to each type of vehicle so a modification to accommodate particular functions has no effect on other vehicles.
- the legs ensure that the cleat is positioned in the right place.
- the legs 73 do not take up stress to relieve the lock which is crushed upon impact.
- the space or clearance J between the locking means 50, in particular the wedge of the window guide 70, and the lock is compensated so as to attenuate, or even eliminate, any vibration and vibratory noises.
- a damping element in particular foam, is arranged between the locking means and the lock.
- the wedge 51, 51 has a shape, or concave portion in the form of a curved ramp, intended to easily interfere with the pivoting of the lever 32 in the event of the lever being moved closer to interior panel 12.
- the wedge 51 ' may have a volume substantially equal to half of volume of the wedge 51, and substantially have the shape of a "slide".
- a gap B in the vertical direction between the bottom 32B of the convex portion 321 and the top 52'B of the concave portion 52 'of the wedge is provided.
- This distance B, illustrated in FIG. 9, is for example between 3 mm and 7 mm, for example 5 mm.
- teeth 54, 54 'of small dimension that is to say of height H ranging for example between 0.3 mm and 1 mm (embodiment in figures 6 and 7 and first variant illustrated in figures 8 and 9) are advantageously provided on the concave portion 52, 52 '.
- the teeth are for example arranged next to each other in the manner of a gear pinion, for example.
- the shape of the section of each tooth along a vertical and transverse plane is for example triangular or substantially identical to the shape of a pinion tooth.
- Teeth 54 "of large dimension, that is to say of height H" between 1 mm and 3 mm (second variant illustrated in Figures 10 and 11) are advantageously provided on the concave portion 52 ".
- the teeth 54 ” are for example spaced from each other by spaces e.
- the shape of the section of each tooth 54 ”along a vertical and transverse plane is for example square or rectangular.
- the spaces e between teeth extend for example radially over an angle A2 greater than the angle A1 over which each tooth extends radially (illustrated in Figure 1 1).
- the pivoting lever may comprise notches or teeth capable of interlocking between the teeth 54, 54 ', 54 ”so as to limit or even avoid any sliding between the wedge and the lever during the pivoting locking.
- the part receiving the locking means is the lock.
- the modifications linked to this new function of the lock are compatible with the constraints of implantation of the lock.
- the wedge or wedging zone is attached to the window guide.
- the window guide then comprises, or not, a predisposition or reception interface of the wedge, in particular so as to facilitate the manufacture and / or the assembly / assembly process.
- the wedge 51 can be mounted on the lock and / or on the window guide 70, for example beforehand, it is easy to install within the door. Indeed, we can do without fixing points for the wedge on the inner panel 12 or on the outer panel 1 1, for example on the sheet metal. In this case, mounting the wedge does not require screwing in screws in areas that are visible and / or too complex and / or difficult to access from the door. If the wedge is integral with the window guide, the absence of screws to provide and to screw to ensure the fixation of the wedge saves time and money.
- the wedge can be assembled directly on the window guide by screwing using the fixing interfaces of the window guide on the box, which advantageously avoids the creation of other holes directly through the box 12.
- the wedge As the wedge is integrated and / or fixed and / or assembled to a part having another function, it is easier to position it within the door. This also makes it possible to dispense with a step of fixing the wedge on the body of the door which would be complex, for example on the interior panel.
- the convex portion 321 of the pivoting lever 32 comes into contact with the concave portion 52, that is to say complementary or substantially complementary, of the wedge 51. Thanks to the teeth and / or notches which increase the grip and consequently the stopping capacity, the pivoting lever 32 is prevented from pivoting in the S direction.
- the transmission system 40 cannot then transmit movement to the lock 20.
- the lock 20 is then locked closed, in particular from the external opening control 30.
- the door 10, after a side impact F therefore remains closed and protects the occupants in the vehicle 1.
- the solution therefore achieves the desired objective of stopping the pivoting of the external opening control lever following an impact and has the following advantages:
Landscapes
- Lock And Its Accessories (AREA)
