Description

COVER OPENING CONTROL OF A MOTOR VEHICLE AND VEHICLE

EQUIPPED WITH SUCH AN ORDER

The present invention relates to a hood opening control of a motor vehicle and a motor vehicle equipped with such a control.

The opening control of the hood of a vehicle comprises in known manner a gripping member such as a lever connected to a cable to unlock the cover lock. An example of such a command is given by document FR2376455, according to which the command fulfills only this first function of opening control.

It is known to use the hood opening control bracket to attach the front foot trim or electrical harness. For this purpose, the control will present at its support passage holes for staples. However, because modern vehicles are carrying more and more electronic and electrical equipment, the diameter of the electrical harnesses connected to this equipment is becoming more and more important. Some beams can reach diameters of 30 to 45 mm becoming too important for fastening by staple.

To remedy this, it has been proposed to make the bonnet opening controls ducts for the passage and maintenance of at least one bundle of electrical son. A control whose support has such a chute is described in WO201 1095723.

This solution is nevertheless not entirely satisfactory because it lacks adaptability. Indeed, the diameter of the electrical harnesses that it will maintain is different from one model of vehicle to another. Said diameter can also vary on the same model depending on the options installed on the vehicle, so that it is necessary to anticipate the choice of vehicle options at the time the hood opening control is installed.

Indeed, the beam (s) may be too big for a given chute size and it will be necessary to switch to a larger model. On the contrary, the beams may be too small and present a clearance with the chute. When driving the vehicle, this game will cause vibration and therefore noise.

There is therefore a need for more adaptability of this type of control fulfilling the dual function of control of hood opening and support of electrical harnesses. In particular, there is a need for a hood opening control having means for maintaining electrical harnesses which are able to handle different beam diameters satisfactorily.

The invention aims to meet at least one of the disadvantages presented by the prior art by proposing a new hood opening control whose support has means for holding in position at least one electrical harness, which generates no noise when driving the vehicle and does not require to anticipate its diameter so far.

The invention also relates to a remarkable vehicle in that it comprises a hood opening control as defined above.

As will be understood from reading the definition that has just been given, the invention consists in proposing a new hood opening control whose support comprises means for managing the maintenance of at least one beam on the one hand able to receive beams of different diameters, but also able to maintain them in position regardless of the diameter presented by these beams so as not to generate noise. Preferably, the invention proposes to individually manage the different electrical beams, each being received individually in a chute or clamp.

The invention will be well understood and other aspects and advantages will become clear from reading the description which follows, given by way of example, with reference to the accompanying drawing plates in which:

- Figure 1 is a perspective view of a hood opening control of a motor vehicle according to the invention.

- Figure 2 is a sectional view along a horizontal plane having the support of a hood opening control according to the invention and the arrangement of the beams in the support.

Figures 3 to 5 illustrate the installation kinematics of the opening control in the vehicle.

In the following description, the term "understand" is synonymous with "include" and is not limiting in that it allows the presence of other elements in the device, the arrangement or the vehicle to which it refers. It is understood that the term "understand" includes the words "consist of".

Similarly, the terms "lower", "upper", "forward", "rear", "longitudinal" and "transverse" will be used in relation to the general orientation of the vehicle. For example, "Inferior" will mean a greater ground proximity than "higher" along the vertical axis.

Reference will firstly be made to FIG. 1 showing an opening control 1 of the hood of a motor vehicle comprising a gripping member 3, for example a lever, pivotally mounted along an axis 5 on a support 7, the support 7 including means for securing it to the vehicle body. The gripping lever 3 is intended to be actuated manually, for example by the driver of the vehicle. It is intended to be connected to a cable (not shown) which is itself connected to the hood lock. As such, the support 7 comprises a tubular nozzle 9 for the passage of the cable.

The support 7 further comprises at least one chute 1 1 for passing and holding one or more electrical harnesses and / or at least one clamp 27 for holding one or more electrical harnesses 25.

In the embodiment of the invention illustrated in Figures 1 to 5, the support 7 has a chute 1 1 and a clamp 27 in the form of a fastening clip. Nevertheless, the person skilled in the art can envisage making a support comprising one or more chutes but no clamp, or a support comprising one or more clamps. without chute. Similarly, the clamp may be in a form other than a fastening clip, with at least two articulated branches and elastic pressure means formed by a spring arranged to exert a force on the branches to bring them closer together. the other. Nevertheless, according to a preferred embodiment of the invention the support 7 comprises at least one chute 1 1. The chute 1 1 is sized to receive and maintain one or more electrical beams, but preferably it is sized and configured to receive only one of a diameter of the order of 30 to 35 mm. According to the invention, the channel or chutes 1 1 comprise elastic pressure means 15 configured to press the electrical bundle or bundles against the inner wall of said choke or chutes 1 January. Advantageously, the elastic pressure means 15 are supported on the wall of the chute to exert pressure on the electrical beam or beams passing through it.

According to a preferred embodiment of the invention, the elastic pressure means 15 consist of at least one resilient tongue 15 connected by one of its ends to the body of the chute 1 1, the other end being free. Preferably, they comprise a plurality of elastic tongues 15 regularly distributed according to the height of the chute. For example, they comprise two resilient tongues each placed at one end of the chute so that an upper and a lower tongue can be distinguished. Referring now to Figure 2, it can be seen that the tongue or tabs 15 are arranged to extend inside the chute 1 1 and dimensioned to present at rest a maximum distance with the wall against which is intended to the electrical harness 13 which is smaller than the diameter of the electric harness 13 of smaller diameter than it is intended to maintain is plated. In this way, when the beam 13 is placed in the chute 1 1 it is pressed against the wall of the chute 1 1 regardless of its diameter. It will be understood that the elastic means 15 serve to compensate any play between the harness 13 received in the chute 1 1 and the chute 1 1. By exerting a constant pressure on the electrical harness 13, the latter is held in position against the wall of the chute 1 1 and will not generate noise during the rolling of the vehicle. Thanks to the invention, it is therefore possible to effectively maintain electrical beams of different sizes within a chute of the support of an opening control.

The chute 1 1 preferably has a substantially tubular shape and is dimensioned to have a diameter greater than or equal to the diameter of larger beam diameter 13 that it is intended to maintain by this means. Preferably, the chute 1 1 receives a single electrical harness 13 and has a substantially circular section so as to match the shape of the harness 13 it receives.

Preferably, the elastic tab or tabs 15 are integral with the chute 1 1. More preferably, the elastic tongue (s) 15 are placed facing the apertures formed in the wall of the chute 1 1 and allowing the tongue to escape through the light when the size of the electric harness 13 requires it.

According to a preferred embodiment of the invention, the support 7 of the hood opening control 1 comprises two parts (17, 19), a fixed part 17 intended to be fixed on the body 21 of the vehicle and a moving part. 19 to be fixed on the fixed part 17. Preferably, the movable part 19 is fixed on the fixed part 17 by snap-fastening means 33. The movable part 19 is fixed on the fixed part 17 by at least two points. fixing 33.

Figure 3 shows the fixed portion 17 of the support in place on the body 21 of the vehicle. It therefore has for this purpose means 23 for fixing the order to the vehicle body. In our example, these means comprise holes for the passage of fixing screws 23 intended to cooperate each with a nut on the vehicle body. Nevertheless, other attachment methods may be envisaged by those skilled in the art such as snap-fastening means. The fixed part may also have positioning pins and / or holding adapted to be able to engage each in a hole presented by the body. These pins temporarily fix the opening control according to the invention before its final fixing by means of a screw.

According to a preferred embodiment of the invention, the support 7 will ensure the maintenance of at least two electrical bundles (13, 25) and at least one of these bundles is not maintained by a chute but by a clamp 27 , preferably being in the form of a fastening clip 27. Preferably the clip comprises at least two branches (29, 31) for retaining the beam 25. Advantageously, the largest diameter electrical beam 25 is retained by the clip 27.

Preferably when the support 7 is in two parts and has at least one chute 1 1, each portion (17, 19) of the support comprises at least one gutter, the gutters being arranged to be placed facing one of the other when fixing the movable portion 19 on the fixed portion 17 of the support so that at least one chute 1 1 is formed by the assembly of the two parts (17, 19).

Similarly, and preferably, when the support 7 is in two parts and that it has at least one clamp 27, each part of the support carries at least one branch (29, 31) intended to form a clamp, the branches being arranged to be placed facing each other during the attachment of the movable part 19 to the fixed part 17 of the support so that at least one clamp is formed by the assembly of the two parts.

Thus, as illustrated in FIG. 3, the fixing of the fixed part 17 of the support on the box 21, offers to the person skilled in the art a half-chute formed by a gutter and a half-clamp ready to receive the electrical bundles intended to be held in the hood opening control bracket.

The skilled person will therefore implement the electrical harnesses as shown in Figure 4 before closing the support of the hood opening control by fixing, for example by snapping, the movable part 19 on the fixed part as shown in Figure 5.

Preferably, and to facilitate the holding in position of the beams in the troughs 1 1 before closing the support 7 by assembling its two parts (17, 19), the elastic means 15 of the chute 1 1 are carried by the part mobile 19 of the support. More preferably, and so that the difference in diameter of the electrical bundle or bundles maintained in position by the clamp (s) 27 does not modify the bulkiness presented by the door opening control 1, and the elastic means are formed on the the branches 29 carried by the fixed part 17 of the support. As illustrated, the branch 31 carried by the movable portion 19 of the support has a stiffness greater than that carried by the fixed portion 17 of the support. If necessary, this rigidity of the branch 31 of the movable part 19 is such that this branch is dimensionally stable and has for this purpose stiffening ribs.

The adjustment of the clamp 27 to the diameter of the beam 25 will be obtained by the elasticity presented by the branch or branches 29 carried by the movable portion 17 of the support. For this purpose the branch 29 constituting an elastic pressure means will be less thick and / or less high than the other branch 31.

Also any modification of the diameter of the harness 25 maintained in the clamp 27 will be between the support 7 and the vehicle body, which allows to maintain a constant size of the door opening control 1.

According to a preferred implementation of the invention, the gripping member 3 is carried by the movable portion 19 of the support so as not to interfere during the introduction of the electrical harnesses (13, 25).

More preferably, the fixed 17 and movable parts 19 are molded of plastic material, preferably the plastic material is a polypropylene resin, polyamide, polyphthalamide, polyetheretherketone, phenylene polysulfide, polyamideimide, polyetherimide, polyarylamide, polyepoxide, unsaturated polyester, vinylester or polyestervinyl ester.
