Description

Holding handle assembly for a motor vehicle

The present invention generally relates to a holding handle assembly, and more particularly to a holding handle assembly for a motor vehicle.

Vehicle grab handles are well known in the art. Usually, these systems are placed above a passenger seat of the motor vehicle to bring more comfort to a passenger. Reference can be made to US 6 643 897 which discloses a vehicle holding handle. Such a holding handle is attached to a wall of the vehicle body by means of two hooks located in two separate locations on said wall.

A conventional motor vehicle may also include a reading lamp for providing light to a passenger to enable him to perform several actions, such as reading, while the vehicle is traveling at night. These reading lamps are generally placed above a passenger seat, together with a switch assembly that allows the passenger to turn on or turn off the reading light. In addition, a reading light is generally placed in the wall of a vehicle body to emit light in a specific direction, usually where a passenger seated in the passenger seat holds an object and, as a book, a computer, etc.

In view of the foregoing, the establishment of a holding handle and a reading lamp above a seat of a motor vehicle involves the fixing of a large number of parts on the wall of the vehicle. a vehicle body, in particular several hooks for attaching the holding handle, a housing for the reading lamp and a housing for the reading lamp switch. These pieces must be put in place in a small space. Therefore, it is usually considered difficult to implement a holding handle and a reading lamp over a passenger seat of a motor vehicle.

In addition, the fixing of a large number of parts is an operation that requires time and qualified manpower. The number of parts to be fixed is even more important if a holding handle and a reading lamp must be fitted above each passenger seat of the vehicle. Therefore, the current configuration of grab handles and reading lamps for motor vehicles increases the overall cost of the vehicle.

In addition, because of the limited space available for placing the grab handle assembly and the reading lamp, the switch assembly is quite difficult to reach for the passenger, which results in difficulty for the passenger. passenger to turn on or off the reading light or to use the grip.

The object of the invention is to propose a solution to the aforementioned drawbacks.

More specifically, an object of the invention is to provide an assembly comprising a holding handle and a reading lamp, which is able to give a passenger maximum comfort, while making it easier to attach to a wall of a vehicle body, saving space and making the order easier for a passenger seated in a passenger seat.

According to a first aspect of the invention, a carrier grip assembly for a motor vehicle comprises a main handle portion and at least one attachment means, said main handle portion being adapted to be secured with said fastening means. to a vehicle wall, said holding handle assembly including a light source adapted to at least partially illuminate the environment of the handle assembly.

The handle assembly further includes a cylindrical portion rotatable about its own axis relative to the main handle portion, rotating the cylindrical portion about its own axis to control the emission of light produced. by the light source. With such an assembly, the holding handle and the reading lamp are provided in one piece. In addition, since the light source is controlled by the rotation of the cylindrical portion, there is no longer a need to add a switch assembly to control the light source. This gives an assembly that is easier to install, easier to control and saves space.

According to one embodiment, the light source is mounted on the cylindrical portion.

With this arrangement, the cylindrical portion may be adapted to turn on the light when the light source is directed to a passenger seat of the vehicle, and to turn off the light when the light source is directed toward the vehicle wall. In addition, such an arrangement makes it possible to adjust the orientation of the light so that the passenger can optimize the lighting when he performs different actions, such as reading and applying makeup, which require lighting in different places.

In another embodiment, said light source comprises at least one light-emitting diode, said light-emitting diode being preferably a Type 1 or smaller LED light-emitting lamp. A type 1 94 diode is a type of diode well known to those skilled in the art, under the corresponding English name "194 led bulb".

The use of such a small light source saves more space in order to reduce the overall size of the assembly, increase the mechanical strength of the holding handle or place more light - emitting diodes in only one set.

Advantageously, the holding handle assembly further comprises a conductive path, said light source being electrically connected to said conductive path, said holding handle assembly further comprising a switch assembly adapted to prevent current flow. in said conductive path, said switch assembly being controlled by rotating the cylindrical portion relative to the main handle portion.

With this switch assembly, the light source can be turned on and off easily by the passenger despite the presence of a holding handle. In particular, the passenger can turn on and off the light source while holding the grip, with one hand.

Preferably, said switch assembly includes a first conductive surface and a second conductive surface, said conductive path including a first conductive wire that is in direct contact with said first conductive surface, and a second conductive wire that is in direct contact with said first conductive surface; second conductive surface, the cylindrical portion having a conductive circuit which is arranged to be in direct contact with said first conductive surface and said second conductive surface when an angle of rotation of said cylindrical portion with respect to said main handle portion reaches a first value, and so as not to be in contact with at least one of said first conductive surface and second conductive surface when said rotation angle reaches a second value, different from the first value.

In a particular embodiment, said main handle portion is divided into a first sub-portion and a second sub-portion, said first sub-portion being positioned at a first longitudinal end of said cylindrical portion, said second sub-portion being placed at a second longitudinal end of said cylindrical portion, said first conductive surface and said first conductive wire being located in said first sub-portion, said second conductive surface and said second conductive wire being located in said second sub-portion.

In another embodiment, said main handle portion has an upper shell and a lower shell, said upper shell and said lower shell separated by a separation plane, said light source being connected. electrically to a conductive path included in said separation plane.

With such an arrangement, it is proposed a set of holding handle easier to manufacture, which results in a reduction in the overall cost of the vehicle.

Advantageously, the separation plane also contains the longitudinal axis of the cylindrical portion.

It can also be provided a locking means adapted to prevent rotation of the cylindrical portion relative to the main handle portion.

Such locking means makes the holding handle assembly even easier to use, since it prevents a passenger grasping the handle from turning on or off the light source accidentally or unintentionally.

In a particular embodiment, said locking means comprises a projecting rod extending from a longitudinal end of said cylindrical portion, along the longitudinal axis of the cylindrical portion, and a corresponding region provided on the main handle portion. , said projecting rod extending towards said corresponding region, the locking means further comprising a spring adapted to move the cylindrical portion in translation about its longitudinal axis in order to bring the projecting rod to the corresponding region, said projecting rod being adapted to cooperate positively with said corresponding region.

According to another embodiment, said locking means comprises a mobile ring placed in said corresponding region, and which is rotatably fixed on the main handle part, said locking means comprising a second spring able to move said mobile ring in translation. around the longitudinal axis of the cylindrical portion, the projecting rod being adapted to cooperate positively with an inner surface of said movable ring, said movable ring comprising at least one radial finger which allows a user to move the movable ring by translation with respect to the main handle part. Additional objects and advantages and other features of this invention will be given in the description which follows.

Examples of nonlimiting embodiments will now be described, with reference to the accompanying drawings, in which:

- Figure 1 is a perspective view of a holding handle assembly according to one embodiment of the invention,

FIG. 2 is another perspective view of the holding handle assembly of FIG. 1,

FIG. 3 is an exploded perspective view of the parts of the holding handle assembly of FIGS. 1 and 2, and

- Figure 4 is an axial view of a portion of the holding handle assembly of Figures 1 to 3.

Referring to Figures 1, 2 and 3, a handle assembly 2 is shown. The handle assembly 2 is intended to be attached to a wall (not shown) of a motor vehicle body. More specifically, the handle assembly 2 is intended to be fixed above a passenger seat of the motor vehicle, such as a front passenger seat or a rear passenger seat. The purpose of the handle assembly 2 is to provide more comfort to the passengers.

The handle assembly 2 consists mainly of a main handle portion 4 and a cylindrical portion 6. The main handle portion 4 is adapted to connect the handle assembly 2 to the wall of the handle. body.

An orthonormal base 7 is defined with respect to the main handle portion 4. The orthonormal base 7 comprises a vector X, a vector Y and a vector Z perpendicular to the vectors X and Y.

The cylindrical portion 6 has the shape of a circular cylinder extending along a longitudinal axis Δ (not shown) parallel to the vector Y. The cylindrical portion 6 has a diameter d ₆ . The cylindrical portion 6 has a first axial longitudinal end 8 and an opposite axial longitudinal end 10. The main handle part 4 consists of a first sub-part 12 and a second sub-part 14. As can be seen in Figures 1 and 2, the first and second sub-parts 12 and 14 are arranged so as to surround the cylindrical portion 6. For this purpose, the first subpart 12 and the second subpart are respectively placed near the first end 8 and the second end 10. The sub-parts 12 and 14 are form substantially symmetrical with respect to a plane of symmetry (not shown) perpendicular to the vector Y. Having substantially symmetrical sub-parts 12 and 14 is particularly advantageous since it makes the design and manufacture of the main handle part 4 easier, and then reduces the overall cost of the holding handle assembly 2 .

With reference to FIG. 1, the sub-portion 12 comprises a proximal end 16 and a distal end 1 8. The proximal end 16 is relatively close to the cylindrical portion 6, while the distal end 18 is relatively far from the cylindrical portion 6. More specifically, the proximal end 16 is opposite the first end 8 of the cylindrical portion 6. The proximal end 16 has the shape of a disk perpendicular to the vector Y, having a diameter di ₆ substantially equal to the diameter d ₆ . The distal end 18 is of substantially rectangular shape, perpendicular to the vector X, and having rounded corners. The above description of subpart 12 also applies to subpart 14, the proximal end 16 of which is opposite the second end 10 of the cylindrical portion 6.

The distal end 18 of each sub-portion 12, 14 includes securing means 20. The securing means 20 is provided to secure the corresponding sub-portion 12, 14 to the wall of the body. In the embodiment shown, the fastening means 20 comprises a male connector 22, which may also be called a plug, and a through hole 24. The male connector 22 is intended to cooperate with a corresponding female connector (not shown) placed in the wall of the bodywork. The through hole 24 is intended to receive a screw (not shown) cooperating with a corresponding nut (not shown) of the wall of the body. The fastening means 20 may, however, be of any kind without departing from the scope of the invention, such as a bolt or pair of connectors engaging by pressure.

More specifically, as can best be seen in FIG. 1, the male connector of subpart 12 has a shape slightly different from that of the male connector of subpart 14: the cross section in the plane perpendicular to the vector X of the male connector of the subpart 12 is circular while the same cross section of the male connector of the subpart 14 is rectangular. This is another advantageous feature of the described embodiment which prevents the operator from mounting the holding handle assembly 2 with the wrong side upward.

As can be seen in FIG. 3, the sub-portion 14 includes an upper shell 26 and a lower shell 28. The following description of the upper and lower shells 26 and 28 of the subpart 14 also applies to the hulls which constitute the sub-portion 12. The upper shell 26 has a flat bottom surface (not visible in Figure 3). The lower shell 28 has a flat upper surface 30. When the shells 26 and 28 are assembled to form the sub-portion 14, the lower surface of the upper shell 26 is in contact with the upper surface 30 and the two surfaces form a plane separation plane (not shown) of subpart 14. The separation plane is perpendicular to a vector Z. The upper shell 26 and the lower shell 28 may be connected by any kind of joining means (not shown), such as a press-fit connector, a screw-nut assembly, or a screw and tapped hole assembly.

The lower shell 28 has a curved groove 32 in its upper surface 30. The curved groove 32 extends from the distal end 18 to the proximal end 16. The groove 32 of the lower shell 28 of the subpart 12 contains a first electroconductive wire 34. In addition, the groove 32 of the lower shell 28 of subpart 14 contains a second electroconductive wire 35. The electrical leads 34 and 35 are respectively intended to be electrically connected to the terminals of an electrical power distribution device (not shown), such as an accumulator battery. electric motor vehicle. In the embodiment shown, the wire 34 is electrically connected to a negative terminal of the motor vehicle battery and the wire 35 is electrically connected to a positive terminal of the vehicle battery.

The use of an upper shell and a lower shell to make subparts 12 and 14 is advantageous since it facilitates the manufacture of these subparts by injection molding. In addition, the fact that the shells are connected by a separation plane which contains the wires 34 and 35 facilitates the introduction of a conductive path in the sub-portions 12 and 14.

Subpart 12 has a blind hole 36 which extends inwardly from the proximal end 16. More specifically, the blind hole 36 is in the form of a circular cylinder extending along the axis Δ and having a diameter d ₃₆ . Within the blind hole 36, a lug 38 extends from a bottom surface of the hole 36 to the proximal end 16. The lug 38 has the shape of a circular cylinder extending along the Δ axis and having a diameter d ₃ 8. The lug 38 has a head 40. The head 40 extends radially outwardly relative to the lug 38. The head 40 is delimited radially by a radial outer surface (not referenced) with axial outer splines (not referenced). The head 40 has a circular cylindrical shape and has a diameter d ₄ o which is between the diameters d ₃ s and d ₃₆ . In the embodiment shown, the diameter d ₄ o is substantially equal to half the diameter d ₆ .

The upper shell 26 of the sub-portion 12 has a first sliding slot 42. Similarly, the lower shell 28 of the sub-portion 12 has a second sliding slot 44. The sliding slots 42 and 44 extend towards the interior from the proximal end 16, parallel to the axis Δ. The length longitudinal extent of the sliding slots 42 and 44 does not exceed the longitudinal length of the blind hole 36. The sliding slots 42 and 44 extend radially from an outer surface of the sub-portion 12 to the blind hole 36.

Subpart 14 has a blind hole 45 which extends inwardly from the proximal end 16 and is in the form of a circular cylinder extending along the axis Δ and having a diameter of _{45 mm.} . The diameter d ₄₅ is substantially equal to the diameter d ₃₆ . Within the blind hole 45, a lug 46 extends from a bottom surface of the hole 45 to the proximal end 16. The lug 46 has the shape of a circular cylinder extending along the length of the hole 46. Δ axis and having a diameter d ₄₆ which is substantially equal to the diameter d ₄ o.

As can be seen in Figure 3, the main handle portion 4 has four electrical conductor half-disks 47, 48, 50 and 52. The half-disks 47, 48, 50 and 52 are substantially identical. The half-disks 47, 48, 50 and 52 have a diameter d _h substantially equal to the diameter d ₁₆ . The half-disks 47, 48, 50 and 52 are delimited radially inwardly by a circular cylindrical surface 53. The diameter d ₅₃ of the circular cylindrical surface 53 is between the diameters d ₃₆ and d ₄ o.

The half-disks 47 and 48 are attached to the proximal end 16 of the first sub-portion 12. The half-disks 50 and 52 are attached to the proximal end 16 of the second sub-portion 14. By this arrangement , the half-disc 48 is in direct contact with the electroconductive wire 34 and is electrically connected to the negative terminal of the battery. The half-disk 52 is in direct contact with the electroconductive wire 35 and is electrically connected to the positive terminal of the battery. An electrically insulating material (not shown) is placed so as to avoid the electrical connection between the half-disks 47 and 48, and between the half-disks 50 and 52. As a variant, the half-disks 47 and 50 may be made of an electrically insulating material. The cylindrical portion 6 comprises a first piece 54 and a second piece 56. The pieces 54 and 56 are assembled together along the axis Δ in order to form the cylindrical part 6.

The first piece 54 has the shape of a semi-circular cylinder along the axis Δ. The first piece 54 has a cylindrical outer surface 58 and a flat surface 60. The flat surface 60 is provided with a straight rib 62.

The second piece 56 has the shape of a semi-circular cylinder along the axis Δ, and has a cylindrical outer surface 64 and a flat surface 70. The flat surface 70 has a straight groove 71 whose shape is complementary to that of the straight rib 62. The straight groove 71 and the straight rib 62 cooperate positively to form a pressure engagement connection. As a result, the first piece 54 and the second piece 56 can be mechanically assembled to form the cylindrical portion 6.

The second piece 56 comprises three conical holes 66. The conical holes 66 are placed on the cylindrical surface 64, in a recessed portion 68. In a radially inner position, each conical hole 66 has a through hole (not shown) which receives a diode 72. The LEDs 72 are provided as a light source to provide a passenger with a light such as a reading light. In the embodiment shown, there are three LED bulbs of type 194. These LEDs are advantageous because they are relatively small and relatively bright, so that it is possible to place a large number of LEDs without increasing the size of the LED. In addition, the reduction of the volume proportion of the part 56 taken by the light source makes it possible to increase the volume proportion taken by the material constituting the part 56, in order to increase the resistance. However, the LEDs 72 may be replaced by any other type of light source without departing from the scope of the invention, such as a neon tube or conventional light bulbs. The cylindrical portion 6 further includes a protective glass cover 73 for covering the conical holes 66 and the LEDs 72. The protective cover 73 is substantially rectangular in shape and is fitted into the recessed portion 68.

The LEDs 72 are mounted on a printed circuit (not shown). The second part 56 comprises a housing (not shown) intended to receive the printed circuit. This housing can be placed near a bottom surface of the rectilinear groove 71. The printed circuit includes an electrically conductive path to which the LEDs 72 are electrically connected.

The first piece 54 comprises an electroconductive wire 74 placed at the first end 8 of the cylindrical portion 6. The electroconductive wire 74 comprises two ends 75 electrically connected to a negative terminal (not shown) of the printed circuit. The electroconductive wire 74 has a central portion 77 (not visible in FIG. 3) protruding axially outwardly from the end 8 of the cylindrical portion 6 so as to be in direct contact with at least one of the half In terms practical, the wire 74 passes through two orifices which extend from the end 8 to the flat surface 60, the central portion 77 extending between said two orifices.

Similarly, an electroconductive wire 76 is placed at the second end 1 0 of the cylindrical portion 6. The electroconductive wire 76 is identical to the electroconductive wire 74. The wire 76 has in particular two ends 75 electrically connected to a positive terminal (not shown) of the printed circuit, and a central portion 77 protruding axially outwardly from the end 10 of the cylindrical portion 6 so as to be in direct contact with at least one of the half-disks 50 and 52.

The wires 74 and 76 form with the printed circuit a conductive circuit on which the LEDs 72 are mounted. The scope of the invention is not limited to this particular conductive circuit. It is indeed possible, without departing from the scope of the invention, to replace the son 74 and 76 and the printed circuit by another circuit conductor, as a wire circuit on which are mounted the LEDs 72, connecting the longitudinal ends 8 and 1 0.

With reference to FIG. 4, the central portion 77 of the wire 76 is shown, projecting axially outwardly from the end 10 of the cylindrical portion. The angular range on which extends the central portion 77 is defined by the angles β and γ. These angles correspond to the angles formed between the plane of the flat surface 60 and the respective ends of the angular range on which extends the central portion 77. As shown in Figure 4, in this embodiment, the angles β and γ are defined as follows:

β = γ = 15 °

The first piece 54 further comprises a first projecting rod 78. The rod 78 extends axially outwards from the second axial end 10 of the cylindrical portion 6. The rod 78 has the shape of a circular cylinder whose diameter d ₇ 8 is substantially equal to the diameter d ₄₆ . The diameter d ₇ s is smaller than the diameter d ₅ 3 - The electroconductive wire 76 is arranged to partially encircle the rod 78.

The first piece 54 comprises a second projecting rod 80 which extends radially outwardly from the first axial end 8 of the cylindrical part 6. The rod 80 has the shape of a circular cylinder having substantially the same diameter dso as the diameter d ₇ s. The axial length of the rod 80 is greater than the axial length of the rod 78. The rod 80 comprises external axial grooves (not referenced) substantially identical to those of the head 40.

When the cylindrical portion 6 is mounted on the main handle portion 4, the rod 78 is inserted into the hole 45 and the rod 80 is inserted into the hole 36. To do this, the rod 78 is slid between the half-disks. 50 and 52 and the rod 80 is slid between the half-discs 47 and 48. With this arrangement, the cylindrical portion 6 is held between the sub-portions 12 and 14 of the main handle portion 4, as shown in these figures, the cylindrical portion 6 is able to rotate around its its own axis Δ with respect to the main handle part 4. The cylindrical part 6 is furthermore able to move in translation along its own axis Δ with respect to the main handle portion 4, between a first end position in which the axial end of the rod 80 touches the head 40 of the lug 38, and a second end position in which the axial end of the rod 78 touches the lug 46.

The handle assembly 2 further includes a first spring 82. The diameter d ₂ of the spring 82 is larger than the diameter d ₄₆ and smaller than the diameter d ₅₃ . The spring 82 is inserted into the hole 45 so as to bear against a bottom surface of the hole 45. The opposite end of the spring 82 is supported on the axial end 10 of the cylindrical portion 6. When the cylindrical portion 6 is mounted on the main handle part 4 as shown in Figures 1 and 2, the spring 82 works in compression so that the cylindrical portion 6 is pushed by the spring 82 to the first subpart 12.

The handle assembly 2 comprises a movable ring 84. The ring 84 is delimited radially outwardly by an outer surface having a diameter ds ₄₀ smaller than the diameter d ₃₆ . The ring 84 has two radial fingers 86 that extend outward radially from its outer surface. The radial fingers 86 are arranged opposite each other. The ring 84 is delimited radially inward by an inner surface having a diameter ds 4i slightly larger than the diameter d ₄ o and having internal axial grooves corresponding to the outer axial splines of the head 40 and the outer axial splines of the rod 80. When the cylindrical portion 6 is mounted on the main handle portion 4 as shown in Figures 1 and 2, the ring 84 is inserted into the blind hole 36, the radial fingers 86 being inserted into the sliding slots. 42 and 44. With this arrangement, the ring 84 is rotatably attached to the first subpart 12 and is able to move in translation along the axis Δ relative to the first subpart 12. A second spring 88 is placed inside the hole 36. The diameter dss of the spring 88 is larger than the diameter d ₃ s. The spring 88 is supported on a bottom surface of the hole 36. The opposite end of the spring 88 is supported on a front axial surface of the ring 84. When the cylindrical portion 6 is mounted on the main handle portion 4 as shown in FIGS. 1 and 2, the spring 88 operates in compression, so that the ring 84 is pushed by the spring 88 towards the cylindrical portion 6.

During normal operation of the holding handle assembly 2, the cylindrical portion 6 is pushed toward the first subpart 12, so that the rod 80 bears on the lug 40. In addition, the ring 84 is pushed to the cylindrical portion 6 so that it encircles the rod 80. The outer splines of the rod 80 cooperate with the inner splines of the ring 84. As a result, the cylindrical portion 6 is rotatably secured to the portion of main handle 4.

If the cylindrical portion 6 is moved in translation towards the sub-portion 14, for example following an action performed by a passenger, which compresses the spring 82, the rod 80 approaches the half-disks 47 and 48. At this time the outer splines of the rod 80 further cooperate with the inner splines of the ring 84. In the meantime, the ring 84 is moved towards the sub-portion 12, which compresses the spring 88, the ring 84 is moved away from half-discs 47 and 48. In this configuration, the outer grooves of the rod 80 emerge from the inner grooves of the ring 84. Under these conditions, the cylindrical portion 6 is free to rotate about its own axis Δ with respect to the main handle part 4.

If the aforementioned actions are interrupted, the spring 82 pushes the cylindrical portion 6 towards the sub-portion 12 while the compressed spring 88 pushes the ring 84 towards the cylindrical portion 6. Under these conditions, the outer grooves of the rod 80 is again engage the inner splines of the ring 84 so that the cylindrical portion is rotatably attached to the main handle portion 4. Note that in this particular embodiment, a first spring, a movable ring and a second spring are provided to ensure optimum safety. Indeed, a passenger can seize the cylindrical portion 6 during the taking of a sudden turn by the motor vehicle, which can result in a displacement movement involuntary invoice of the cylindrical portion 6, which causes the disengagement of the flutes The spring 82, on the one hand, and the ring 84 with the spring 88, on the other hand, provide a double locking means for securing the rod 80 from the inner splines of the ring 84. avoid at best any involuntary rotation of the cylindrical part 6.

Nevertheless, one can imagine a different means of locking without departing from the scope of the invention. Possible locking means may for example implement the first spring 82, the ring 84 being fixed. With such a locking means, the second spring 88 may be omitted and / or the ring 84 may be replaced by internal axial splines on the inner surface of the blind hole 36. Another possible locking means may involve only the 84 and the second spring 88, the cylindrical portion 6 being immobilized in translation relative to the main handle portion 4. With such a locking means, the first spring 82 can be omitted.

As can be deduced from FIG. 3, the electric current flowing in the LEDs 72 depends on the angle of rotation α of the cylindrical part 6 with respect to the main handle part 4. More specifically, the angle The rotation angle is the angle between the vector X and a vector n (see Figures 1 and 2). The vector n is oriented along the axis of one of the conical holes 66, outwardly of the cylindrical portion 6.

Referring to Figure 1, in which the cylindrical portion 6 has been rotated so that the LEDs 72 are oriented to illuminate in the direction of the locking means 20, the rotation angle a is zero. Under these conditions, the central portion 77 of the son 74 and 76 touches the half-discs 47 and 50 only. Since the half-disks 47 and 50 are not electrically connected to the battery, the diodes 72 are not supplied with electricity. Under these conditions, the diodes 72 are off.

With reference to FIG. 2, in which the cylindrical portion 6 has been rotated so that the LEDs 72 are oriented in the opposite direction to the fastening means 20, the rotation angle α is 1 80 °. Under these conditions, the central portion 77 of the wires 74 and 76 is in direct contact with the half-disks 48 and 52. Since the half-disks 48 and 52 are electrically connected to the battery via the wires 34 and 35, the LEDs 72 receive an electric current. Under these conditions, they are illuminated and illuminate the environment of the handle assembly.

To ensure the power supply of the LEDs 72, only a portion of the central part of the wires 74 and 76 directly touches the half-disks 47 and 50, respectively. In the embodiment shown, the LEDs 72 receive a power supply as long as the angle of rotation remains between 15 ° and 345 °. The scope of the invention is however not limited to this range of values given by way of example. To modify this range, it is possible to reduce or increase the angles β and / or γ. For example, by choosing an angle β = 25 ° and an angle γ = 35 °, the diodes receive electric current as long as the angle of rotation remains between 35 ° and 325 °.

In view of the above, the assembly 2 provides both a holding handle and a light source to give the passenger of a motor vehicle maximum comfort, while saving space, which makes it more easy to design and assemble with the body.

The switching on and off of the LEDs 72 can easily be achieved by turning the cylindrical portion 6. In addition, the light can be oriented to provide optimum passenger comfort.

With the blocking means shown, it avoids at best the forward switching of the LEDs. In addition, deactivation of the locking means can be easily performed even with one hand. For this, the user can move the palm of the hand the part cylindrical 6 in translation towards the subpart 14, while moving the thumb ring 84 in translation towards the subpart 12.
