Description

Title of the invention: Assembly comprising a vehicle part and a support for the vehicle part on a vehicle chassis TECHNICAL FIELD OF THE INVENTION

[0001] The field of the invention is that of the support, and in particular of the suspension, of vehicle components, parts or subassemblies of vehicle parts on a vehicle chassis.

[0002] More specifically, the invention relates to an assembly comprising a vehicle part and a support for the vehicle part on a vehicle chassis.

[0003] The invention finds applications in particular in the field of vehicles for fixing and suspending vehicle parts on a chassis. The invention finds a particular application in the field of land vehicles and more specifically motor vehicles, in particular for supporting parts that may be replaced during the life of a motor vehicle, and in particular such as heat exchanger frames, which may include in particular the engine cooling radiator, the air conditioning condenser, the oil cooler, the air cooler, etc. The invention can also find applications in the field of trucks, coaches, buses, two-wheeled vehicles, agricultural machinery, construction machinery, or even robotic vehicles, in particular of the autonomous type. STATE OF THE ART

[0004] Techniques for suspending vehicle components, parts or subassemblies of vehicle parts, hereinafter referred to by the generic term "vehicle part", on vehicle chassis are known from the prior art.

[0005] In particular, in the field of motor vehicles and in related fields, support elements are known, commonly called support "pads", generally used to fix a vehicle part such as a heat exchanger frame at a lower point of a chassis.

[0006] When attaching the vehicle part to the vehicle frame, such "pads" are generally first attached to the frame, before the part is placed on the pad and then attached to the pad.

[0007] A “plot” designed in this way involves significant constraints in terms of logistics, the final assembly of the part and the “plot” on the chassis can only be done simultaneously, by the final assembler of the vehicle.

[0008] Thus, the part and its support must be treated, in terms of logistics, as spare parts until the final assembly of the vehicle.

[0009] This is particularly restrictive and costly, and inconvenient due to the management of a high number of spare parts on an assembly line and the resulting difficulty for an operator on the assembly line.

[0010] Additionally, once the vehicle is produced, it may be necessary to remove the part from the chassis when servicing the vehicle.

[0011] Known techniques, in particular “plot” type support elements, require in particular having suitable tools to be able to completely dismantle the part from the support, then to dismantle the support from the chassis.

[0012] Thus, none of the current techniques makes it possible to simultaneously meet all the required needs, namely to propose a technique for supporting a vehicle part on a vehicle chassis, which allows faster, simpler and easier assembly and disassembly of the part on the chassis. Statement of the invention

[0013] The present invention aims to remedy all or part of the drawbacks of the state of the art cited above.

[0014] To this end, the invention relates to an assembly comprising a vehicle part and a support configured to suspend said part on a vehicle chassis, said part comprising a pin for fitting the support, and the support comprising a main body configured to be able to be fitted onto said pin, as well as to be able to be fixed to said chassis, the support further comprising an element for locking said main body on said pin and which can take a locking position and an unlocking position; the assembly being able to take: - at least a first configuration, in which the locking element is in its locking position and the main body is fitted and retained on the pin of said part; and - at least a second configuration, in which the locking element is in its unlocked position, and the pin of said part can be removed from the main body; whereby in the first configuration the support can be pre-mounted on said part before mounting the assembly on the chassis, and whereby in the second configuration said part can be dismantled from said chassis independently of the support.

[0015] Thus, it is possible to pre-mount one or more supports on a vehicle part prior to mounting the assembly on a vehicle chassis, by providing the assembly in its first configuration.

[0016] This makes it possible to improve the logistical management of spare parts for a vehicle, the assembly can be treated as a single element by the supplier and the final vehicle manufacturer. In addition, the number of parts that need to be assembled at the edge of the vehicle assembly line is thus reduced.

[0017] Furthermore, this makes it possible to speed up and make more convenient the mounting of the assembly on a chassis, since it is possible to fix the support directly on the chassis without an intermediate step of mounting the support.

[0018] In the second configuration of the assembly, it is possible to easily replace the vehicle part without requiring significant disassembly and reassembly steps.

[0019] Indeed, the vehicle part can be removed from the chassis by simply manipulating the locking element towards its unlocked position, without tools.

[0020] The main body of the support can remain on the chassis, in order to support a new replacement part, which can be fixed to the chassis by manipulating the locking element towards its locking position, always without tools. The assembly is then returned to its first configuration.

[0021] In summary, thanks to these provisions, the operations of mounting, dismounting and remounting a vehicle part on a vehicle chassis are greatly facilitated, made more convenient and faster.

[0022] Other particularly simple and convenient characteristics of the assembly according to the invention are described below.

[0023] Preferably, the locking element is configured to be able to move from one of its locking and unlocking positions to the other by relative rotation around the pin.

[0024] Preferably, the locking element is configured to be able to move from the locking position to the unlocking position, and vice versa, by relative rotation of a quarter turn around the pin.

[0025] It may also be a rotation of an angle other than a quarter turn, for example a half turn, a third turn, a fifth turn, a sixth turn, an eighth turn, etc.

[0026] Preferably, the pin comprises a rod and an end head, and the locking element is configured to be able to be fitted onto the pin so that the rod passes through the main body and the locking element, the locking element being configured to be able to be removed from the pin when it is in its unlocked position, and to be retained on the pin in abutment against the head in its locked position, so as to also retain the main body on the pin.

[0027] Preferably, the locking element comprises a through opening, the head of the pin and the opening being of complementary shape, the locking element being configured so as to allow the passage of the head through the opening when the locking element is in its unlocked position, and so as to retain the locking element against the head when the locking element is in its locking position.

[0028] Preferably, the head of the pin is substantially T-shaped, and the opening of the locking element is substantially slot-shaped, so as to jointly form a bayonet-type lock.

[0029] The lock can also be of any other type, with the head of the pin and the opening of the locking element cooperating.

[0030] Preferably, the assembly comprises at least one means for holding the locking element in the locking position.

[0031] This allows any untimely change of configuration of the assembly.

[0032] For example, in the assembly, one of the main body and the locking element includes at least one notch, and one of the main body and the locking element includes at least one stop lug configured to be retained in said notch in the locking position of the locking element.

[0033] For example, the locking element comprises at least one ramp configured to cooperate with said pin to retain the locking element in its locking position.

[0034] Preferably, the main body is configured to be fixed to the chassis by snap-fastening.

[0035] The main body may also be attached to the chassis by any means other than elastic fitting.

[0036] Preferably, the elastic casing is reversible here.

[0037] Preferably, the main body comprises fixing members configured to cooperate with the chassis to form an elastic fit, the fixing members being opposite on the main body so as to be able to be manipulated by pinching, and preferably by pinching between two fingers of an individual's hand, to detach the main body from the chassis.

[0038] Thus, if necessary, the main body can be removed from the chassis in a particularly simple and convenient manner, in particular with one hand.

[0039] Preferably, the main body comprises a central part made of a substantially elastic material and which is configured to be fitted onto the pin, and a peripheral part made of a substantially rigid material, intended to be fixed to the chassis.

[0040] Thus, the support performs a shock absorption and suspension function.

[0041] According to a second aspect, the invention also relates to a vehicle, preferably terrestrial, comprising an assembly as described above.

[0042] Preferably, the vehicle is one of a motor vehicle, a truck, a coach, a bus, a two-wheeled vehicle, an agricultural machine, a construction machine, or a robotic vehicle, in particular of the autonomous type. BRIEF DESCRIPTION OF THE FIGURES

[0053] The present description is given without limitation, each characteristic of an embodiment being able to be combined with any other characteristic of any other embodiment in an advantageous manner.

[0054] [Fig.l] schematically and partially represents an automobile chassis 20 on which is mounted an automobile part 10 (shown partially), which is here an automobile radiator frame. Here, the part of the chassis 20 illustrated is a front crossmember of a motor vehicle.

[0055] It is recalled from now on that the invention is not limited to motor vehicles, and that it can be implemented for any type of vehicle, in particular any type of land vehicle. The automobile part 10 and the automobile chassis 20 can thus be other than automobiles.

[0056] The automotive part 10 is mounted on the chassis 20 by means of a plurality of fastening elements.

[0057] The upper part (along the Z axis conventionally used in automotive technology in connection with an XYZ reference as shown in [Fig.l]) of the automotive part 10 is fixed to the chassis 20 by means of an upper support (not shown).

[0058] The lower part of the automotive part 10 is fixed to the chassis 20 by means of supports 100. In the illustrated example, two supports 100 are used.

[0059] Figures 2 to 5 partially represent an assembly comprising the automobile part 10 (partially represented in Figures 2 to 5) and at least one support 100 (a single support 100 is represented in Figures 2 to 5), the assembly here comprising in particular two supports 100 without this number being limiting, in different states of attachment and separation relative to a chassis 20.

[0060] The support 100 comprises a main body 110, intended to be fixed to the chassis 20, and a locking element 120 of the main body 110 on the automobile part 10.

[0061] [Fig. 2] represents the assembly formed by the automotive part 10 (partially shown) and the support 100 in a state separated from the chassis 20 which is not visible in [Fig. 2],

[0062] This state corresponds in particular to a state of the assembly before a first assembly and fixing on the chassis 20, that is to say in a pre-assembly state on the chassis 20.

[0063] In [Fig.2], the support 100 is in a first configuration of the assembly, in which the support 100 is held on the automotive part 10, and locked thereon by means of the locking element 120 which is in a locking position.

[0064] In particular, the automotive part 10 with the pre-assembled support 100 as shown in [Fig.2] can be directly attached to the chassis 20 without requiring disassembly of the support 100 from the automotive part 10.

[0065] [Fig. 3] shows the automotive part 10 (partially shown) attached to the automotive chassis 20 (partially shown) by means of the support 100.

[0066] This state corresponds in particular to a state of the assembly when it is mounted in a vehicle ready for use, or in use.

[0067] The support 100 is also in the first configuration of the assembly in this state. Indeed, here too the support 100 is held on the automobile part 10, and locked onto the latter, with the difference that the support 100 is further fixed to the chassis 20.

[0068] [Fig.4] shows the assembly mounted on the chassis 20, this time in a state in which the automotive part 10 can be removed from the chassis.

[0069] For this purpose, the support 100 is in a second configuration of the assembly, in which the automotive part 10 is no longer retained or locked on the support 100, but simply rests on the latter, the locking element 120 being in an unlocked position.

[0070] Thus, the automotive part 10, when it has been previously mounted on the chassis 20, can be removed from the chassis 20 independently of the support 100 when the assembly is in the second configuration.

[0071] This state corresponds in particular to a state in which the automobile part 10 must be removed from the vehicle on which it is mounted, in order to be replaced.

[0072] L a [Fig.5] represents the chassis 20 (partially shown) on which the main body 110 is fixed, the automotive part 10 having been removed from the latter, and therefore from the chassis 20. The locking element (not shown in [Fig.5]) is also removed from the automotive part 10 in this state.

[0073] A new automotive part, without support, can then be mounted on the main body 110 which remains fixed to the chassis 20, then locked there by means of the locking element 120.

[0074] It should be noted that the locking element 120 may have several locking positions and / or several unlocking positions.

[0075] With reference to Figures 6 to 12, the assembly formed by the automotive part 10 and the support 100 will now be described in more detail.

[0076] Figures 6 and 7 show a portion of the automotive part 10, which may be an automotive heat exchanger frame, also commonly referred to as a radiator frame.

[0077] The automotive part 10 comprises a mounting tab 11, here projecting longitudinally from the automotive part 10, that is to say along the X axis of the vehicle when the automotive part 10 is mounted on a motor vehicle, without such an extension direction being limiting. According to an alternative, the mounting tab may not project from the automotive part 10 but be formed directly in it.

[0078] The mounting tab 11 comprises a bearing face 12 and a pin 13 extending from the bearing face 12.

[0079] In the example illustrated, when the automotive part 10 is mounted in a motor vehicle, the pin 13 extends substantially along the Z axis, downwards from the bearing face 12.

[0080] The pin 13 comprises a rod 14 attached to the bearing face 12, and an end head 15.

[0081] Here, the head 15 is T-shaped, but without being limited to this shape.

[0082] The head 15 is configured to retain the locking element 120 on the pin 13, when the locking element 120 is in the locking position.

[0083] .

[0084] Figures 8 and 9 show the main body 110 of the support 100.

[0085] In the example illustrated, the main body 110 is substantially rectangular parallelepiped without this shape being limiting, and comprises an upper face 111, a lower face 112 opposite the upper face 111, and a plurality of walls 113 connecting the upper face 111 and the lower face 112.

[0086] As can be seen in [Fig. 3], the automotive part 10 is intended, via its bearing face 12, to rest on the upper face 111 of the main body 110.

[0087] The upper face 111 is substantially widened relative to the rest of the main body 110, thus forming a peripheral rim 115 extending from the walls 113.

[0088] Thus, the lower face 112 has dimensions that are substantially smaller than those of the upper face 111.

[0089] In addition, preferably, the main body 110 flares substantially from the lower face 112 towards the upper face 111, being wider at the upper face 111.

[0090] In other words, the walls 113 together form a funnel shape, or a substantially truncated cone shape. Such a shape allows for easy introduction and guidance of the main body 110 into the support portion 21 described below.

[0091] [Fig. 10] shows the chassis 20 which comprises a support part 21 comprising an opening 22 for fixing the main body 110. Here, the support part 21 has the form of a plate projecting from the chassis 20. The support part 21 can be attached to the chassis 20, or be in one piece with the latter.

[0092] The opening 22 is of substantially rectangular shape, without this shape being limiting, complementary to the section, here substantially rectangular, of the main body 110 under the rim 115.

[0093] In this way, the main body 110 can be introduced into the opening 22 by its lower face 112, until it abuts against the rim 115. Thus, the main body 110 can rest along the Z axis on the chassis 20.

[0094] In order to fix the main body 110 to the chassis 20, the main body 110 comprises a member for fixing the support 100 to the chassis 20, here on each of two opposite walls 113. However, any other number and / or arrangement of fixing members is possible.

[0095] The fixing member is here a tab 116, or clip, for example substantially rectangular, extending by one of its sides which is proximal to the lower face 112 from a wall 113, its distal side of the lower face 112 being free. The tab 116 projects slightly towards the outside of the main body 110, from the wall 113 from which it extends, and has a capacity for elastic deformation at the level of its side by which it is attached to the wall 113.

[0096] Preferably, the distance between the side of the tongue 116 which is distal from the lower face 112, and the rim 115, corresponds substantially to a thickness of the plate forming the support part 21 of the chassis 20.

[0097] Thus, the tab 116 forms a fixing member by elastic fitting, also called snap-fastening, in the opening 22 of the support part 21, the tab 116 being able to deform elastically during insertion through the lower face 112, then return to its initial position.

[0098] It should be noted that this snap-on attachment is not necessarily definitive, and can be reversible by manipulating the tab 116.

[0099] It should also be specified that any other type of fixing can be envisaged, and that this can in particular be adapted according to the fixing point provided on the chassis 20 which must be equipped with the assembly.

[0100] Furthermore, the main body 110 comprises an opening, called the first opening 117, which is here a through opening, configured for the insertion of the pin 13. The first opening 117 extends substantially along the Z axis when the automobile part 10 is mounted in a motor vehicle, and is here substantially centered on the main body 110.

[0101] When the pin 13 is fully inserted into the main body 110, the bearing face 12 of the automotive part 10 and the upper face 111 of the main body 110 are in contact.

[0102] The pin 13 has a length substantially greater than the height of the main body 110 along the Z axis, that is to say the distance separating the ends of the upper face 111 and lower face 112.

[0103] Thus, the pin 13 passes through the main body 110 when it is inserted into the latter, and protrudes from it on the side of the lower face 112, as can be seen in FIGS. 2 and 3 in particular.

[0104] According to an alternative, the first opening 117 may not be a through opening and / or the pin 13 may not pass through the main body 110 when it is inserted into the latter, in particular in a case where the pin 13 is of a height less than the height of the main body 110.

[0105] [Fig. 11] and [Fig. 12] show the locking element 120 of the support 100.

[0106] The locking element 120 has the general shape of a rectangular plate, however without being limited to this shape, with dimensions corresponding substantially to those of the lower face 112 of the main body 110.

[0107] The locking element 120 has an upper face 121 and a lower face 122, the upper face 121 being intended to come into contact with the lower face 112 of the main body 110, and the lower face 122 being intended to come into contact with the head 15 of the pin 13 in the locking position of the locking element 120.

[0108] In its locking position, the locking element 120 is substantially aligned with the lower face 112, and is in the extension thereof, as shown in [Fig.2] and in [Fig.3]. Thus, when the locking element 120 is mounted with the main body 110 on the pin 13, the entire support 100 can be inserted into the opening 22 of the chassis 20, to be fixed there.

[0109] The locking element 120 comprises an opening, called the second opening 123, which is here central and through, substantially aligned with the first opening 117 of the main body 110 when the two elements are mounted on the pin 13.

[0110] The second opening 123 is substantially in the form of a slot, with dimensions corresponding in the example illustrated to those of the upper branch of the T-shape of the head 15, without this shape being limiting.

[0111] In this way, the second opening 123 and the head 15 here jointly form a bayonet-type lock, lockable and unlockable by relative rotation of the locking element 120 relative to the pin 13.

[0112] In the locking position, the upper branch of the T shape of the head 15 forms a stop with the lower face 122 of the locking element 120, and the locking element 120 is taken between the upper branch and the main body 110. The locking element 120 and the main body 110 are thus retained on the pin 13, and the automobile part is thus mechanically secured to the chassis 20.

[0113] In the illustrated example, the slot formed by the second opening 123 and the upper branch of the T-shape of the head 15 are orthogonal to each other in the locking position of the locking element 120.

[0114] Thus, the lock formed by the second opening 123 and the head 15 is here of the quarter-turn bayonet type, the relative rotation for the passage from a locking position to an unlocking position being a quarter turn.

[0115] However, any other orientation of these elements can be chosen, as long as the orientation of the upper branch of the T-shape of the head 15 and the orientation of the slot of the second opening 123 differ from each other in the locking position of the locking element 120.

[0116] In summary, in the first configuration of the assembly, the main body 110 is in abutment against the bearing face 12, the locking element 120 is in abutment against the lower face 112, and the head 15 is in abutment against the locking element 120 which is in the locking position, that is to say with the slot of the second opening 123 and the upper branch of the T-shape of the head 15 which are substantially orthogonal to each other.

[0117] In the first configuration of the assembly, the support 100 can thus be pre-mounted on the automobile part 10 by means of the locking element 120, and can be fixed on the chassis 20 by means of the fixing members formed for example by tabs 116, without requiring manipulation of the locking element 120 or dismantling of the support 100 from the automotive part 10.

[0118] In the second configuration of the assembly, unlike the first configuration, the locking element 120 is in the unlocked position, that is to say that the slot of the second opening 123 and the upper branch of the T-shape of the head 15 are substantially aligned, and the lower face 122 of the locking element 120 is no longer in abutment against the head 15. The pin 13 can thus be freely removed from the main body 110, and the automobile part 10 can be dismantled from the chassis 20.

[0119] In the second configuration of the assembly, the main body 110 therefore does not have to be removed from the chassis 20 in order to be able to remove the automobile part 10 from the chassis 20. In particular for this reason, a fixing of the main body 110 by snap-fastening onto the chassis 20, which is particularly practical when mounting the assembly on the chassis, can be envisaged.

[0120] It should be noted that the support 100 can be fully reused when changing the automobile part 10, the main body 110 being able to remain in place on the chassis, and the locking element 120 being temporarily removed before being used again to lock the pin 13 of the new automobile part 10 on the main body 110.

[0121] It should be specified that any other embodiment, in particular of the locking element 120 and of the pin 13, in particular by means of any other shape and / or material of these elements, can be envisaged to perform the function of locking and unlocking the main body 110 on the pin 13.

[0122] When such a function is performed by a relative rotation of the locking element 120 and the pin 13, any other structural design than that described, making it possible to perform the function of locking and unlocking the main body 110 on the pin 13 by relative rotation, can be envisaged.

[0123] Now, other particularly advantageous characteristics of the assembly will also be described below.

[0124] - The assembly may comprise at least one means for holding the worm element 120 rust in lock position.

[0125] For example, the lower face 112 of the main body 110 may include one or more stop lugs 118 projecting from the lower face 112. For example, the lower face 112 may include two stop lugs 118 disposed at opposite sides of the lower face 112, for example at the edge of the first opening 117 of the main body 110.

[0126] The locking element 120 may comprise one or more notches 125 of a shape complementary to the stop lugs 118, made in the upper face 121.

[0127] Thus, in the locking position of the locking element 120, the stop lug(s) 118 are housed in the notch(s) 125 and limit the risk of unexpected rotation of the locking element 120.

[0128] When moving the locking element 120 into the unlocking position, and vice versa, a slight axial play on the pin 13 and / or a slight elastic deformation of the stop lugs 118 may be exerted to dislodge the stop lugs 118 from the notches 125, and move the locking element 120 into the unlocking position.

[0129] It should be noted that the arrangement of the stop lugs 118 and the notches 125 may be reversed, i.e. the locking element 120 may comprise lugs and the main body 110 may comprise notches.

[0130] Furthermore, as an alternative or in addition, the locking element 120 may also comprise at least one ramp 126 configured to cooperate with the pin 13, to retain the locking element 120 in its locking position.

[0131] For example, each ramp 126 may be formed by a central track 127 formed on the lower face 122, and which is substantially concave towards the lower face 122, defining a groove in which a branch of the T shape of the head 15 can be housed.

[0132] The ramp 126 may comprise, at one of its ends, a protrusion 128 projecting from the lower face 122, and forming a stop for the head 15 limiting its relative rotation with respect to the locking element.

[0133] For example, the ramp 126 is located on the lower face 122 so that a portion of the upper branch of the T-shape of the head 15 is housed in the ramp 126 when the locking element 120 is in its locking position, at the end of the locking movement.

[0134] In the illustrated example, the locking element 120 comprises two ramps 126 located at opposite sides of the locking element 120, each ramp 126 being intended to receive an opposite portion of the upper branch of the T-shape of the head 15.

[0135] Here also, the transition from a locking position to an unlocking position, and vice versa, is made possible by a slight elastic deformation of the main body 110 and / or of the ramp 126.

[0136] It should be noted that a preferred unlocking direction can be defined using the means for holding the locking element 120 in the locking position.

[0137] Other embodiment variants, freely combinable with each other and with the example described above, are described below.

[0138] - The pin 13 may have a head 15 different from an upper branch of a T, and may for example comprise a head 15 having the shape of a polygonal plate formed at the end of the rod 14, being substantially orthogonal to the latter. second opening 123 of the locking element 120 is then of a shape substantially complementary to the shape of the polygonal plate, so as to form a lock by complementarity of shape of the head 15 and the second opening 123.

[0139] - For example, the polygonal plate shape of the head 15 and the shape of the second opening 123 can be: triangular, square, pentagonal, hexagonal, etc. The shape can also be a non-regular polygonal shape.

[0140] - When the assembly comprises two supports 100, the automotive part 10 can comprise two pins 13 each of a substantially different shape, making it possible to compensate for any expansion of the automobile part 10 and / or a dispersion of manufacturing tolerances.

[0141] - The locking element 120 may have one or more, for example two, gripping fins 124, in order to facilitate its passage from a locking position to a locking position, and vice versa.

[0142] For example, the fins 124 may protrude from the general plate shape of the locking element 120, from the lower face 122.

[0143] For example, the fins 124 may each have an outer edge inclined relative to the lower face 122, towards the center of the locking element 120, for example substantially at the same angle as that defining the flared shape of the main body 110, the fins 124 thus extending in the extension of the latter. This also makes it easier to insert the support 100 into the opening 22 of the support part 21.

[0144] - The main body 110 of the support 100 may be in one piece. For example, it may be made of substantially elastic material, suitable for damping vibrations exerted on the automotive part 10.

[0145] - Alternatively, the main body 110 can be made from several added parts.

[0146] For example, the main body 110 may comprise a central part configured to be fitted onto the pin, comprising in particular the upper face 111, the lower face 112 as well as the first opening 117, and a peripheral part, intended to be fixed to the automobile chassis, comprising in particular the walls 113 and the fixing members, formed for example by tabs 116. The two parts may be assembled to each other for example by force fitting, or snap-fastening or elastic fitting, or overmolding or other method.

[0147] Furthermore, the central portion may be made of a substantially elastic material, for example rubber, suitable for damping vibrations exerted on the automotive part 10, and the peripheral portion may be made of a substantially rigid material, for example polyamide. Thus, the support 100 may form a support for suspending the automotive part 10 on the chassis 20.

[0148] - According to a variant, the locking element 120 is configured to be able to pass from the locked position to the unlocked position, and vice versa, by translation.

[0149] - For example, the second opening 123 of the locking element 120 has a first wider portion, through which the head 15 can pass, and a narrower portion, through which the head 15 cannot pass. In the locking position, the locking element 120 is positioned with the narrower portion of the second opening 123 facing the head 15, which then abuts against the locking element 120, and in the unlocking position, the locking element is moved by translation with the wider portion of the second opening 123 which is facing the head 15, which can then pass through the second opening 123.

[0150] It is recalled that the present invention is not limited to the examples described and illustrated.
