Description

Title of the invention: arrangement of a device to assist in loading the trunk of a motor vehicle.

[0001] The invention relates to an arrangement of a loading aid device in a motor vehicle trunk delimited by a floor, side walls, a front wall formed by the backrests of a row of seats and a rear opening movable between an open position and a closed position, the opening having an upper part formed by a frame, inside of which is mounted a glazed panel, the upper transverse band of the frame being mounted to rotate around a rear edge of a roof of the vehicle and a lower part whose lower edge comes to rest near the floor in the closed position.

[0002] It is often difficult for users loading their trunk to visually assess whether the door will close easily without being obstructed by the contents, such as luggage. The user must then place the luggage in the trunk, close the door to check that it closes, and then reopen it if necessary and rearrange the luggage. The user must then repeat these operations as many times as necessary until a satisfactory load is achieved.

[0003] In order to overcome these drawbacks, the invention relates to an arrangement of a device to aid in loading a trunk which is practical, efficient and of simple design.

[0004] To this end, the invention proposes an arrangement of the type mentioned above, characterized in that the opening comprises at least two lighting means capable of emitting each a light beam when the opening is in the open position, the beams being oriented so that their intersection corresponds to a point included in the connection zone of the upper and lower parts of the opening in the closed position.

[0005] According to other features of the invention:

[0006] A first lighting means is carried by an interior trim element of the upper band of the opening frame and a second lighting means is carried by an interior trim element of the lower part of the opening.

[0007] The first and second lighting means are carried by the ends of an interior trim element of the upper band of the opening frame.

[0008] The first and second lighting means are carried by a trim element on the edge of the pavilion.

[0009] The first and second lighting means are carried by a trim element on the edge of the pavilion and a third lighting means is carried by a threshold bar located on the floor.

[0010] The lighting means are laser pointers suitable for being received in holes provided in the cladding elements.

[0011] The orientation of the beam of the lighting means is achieved by means of a shape provided in the cladding element.

[0012] The beam orientation of the lighting means is achieved by means of an asymmetrical ring allowing the axis of the pointer to be oriented.

[0013] The lighting means comprise a single light source illuminating a network of optical fibers opening into holes provided in the cladding elements.

[0014] The light source is a laser generator located on the reverse side of the covering element, the fibers are glued to the reverse side of the covering element and open into supports located in holes.

[0015] Other features and advantages of the invention will become apparent from the description of examples of duct embodiments with reference to the accompanying drawings in which:

[0024] [Fig.9] The [Fig.9] is a schematic cross-sectional view of a second embodiment of the lighting means of an arrangement of a loading aid device according to the invention.

[0025] [Fig. 10] The [Fig. 10] is a schematic cross-sectional view of a detail of the embodiment of the [Fig.9].

[0026] In the following description, we will take, without limitation, a longitudinal, vertical and transverse orientation indicated by the trihedron L,V,T of figures 1 to 5.

[0027] Identical or analogous elements are designated by the same reference numerals.

[0028] With the exception of the specific elements of the driver's seat, the vehicle exhibits general symmetry with respect to a median longitudinal plane.

[0029] As described in figures 1 to 10, a vehicle 10 includes a loading area 12, also called a trunk, delimited by a roof 14, side walls (not shown), backrests 16 of a row of seats 18, a floor 20 of which a rear transverse edge includes a sill bar 21 and a rear opening 22.

[0030] The opening 22 comprises an upper part 24 and a lower part 25.

[0031] The upper part 24 has a frame 26, forming the structure of the opening 22, inside of which is arranged a glazed panel 28. The frame 26 has an upper horizontal band 260, a lower band 262 and two lateral uprights 264.

[0032] The lower part 25 is a solid panel whose plane forms an acute angle with the plane of the upper part 24, the acute angle being directed towards the interior of the vehicle 10. The upper part 24 and the lower part 25 are joined by a connecting area 27.

[0033] A transverse end edge 266 of the upper band 260 of the frame 26 is mounted to rotate by means of a hinge 29 around an axis X carried by a rear transverse edge 140 of the pavilion 14.

[0034] Thus the opening 22 is mounted to rotate around a closed position in which it closes the loading area 12, a lower edge 250 of the lower part 25 then being in contact with the threshold bar 21 and an open position in which the opening 22 is raised so that its lower part 25 is above the plane of the roof 14.

[0035] In the example described here, 30 pieces of luggage are arranged inside the trunk 12.

[0036] In order to prevent these bags from preventing the closure of the opening 22, a device 32 is provided to assist in loading the trunk.

[0037] The loading aid device 32 comprises at least two lighting means El and E2 each emitting a light beam Fl and F2 in the visible light spectrum.

[0038] In the first embodiment described in [Fig.2], the first lighting means El is carried by an interior trim element 34 of the upper band 260 of the frame 26 and the second lighting means E2 is carried by an interior trim element 36 of the lower part 25 of the opening 22.

[0039] When the opening 22 is in the open position, the beam Fl emitted by the first lighting means El is directed downwards and outwards from the vehicle, out of the trunk 12, while the beam F2 of the second lighting means E2 is directed downwards and into the trunk 12. Thus, the beams Fl and F2 intersect at a point A, located in the space at a point corresponding to the junction area 27 of the opening 22 when the opening 22 is closed.

[0040] Thus, when a user places luggage inside the trunk 12, if they observe the projection of a first point PI and the projection of a second point P2 onto the luggage, this means that the point of intersection A is located at the position of the luggage. The user can therefore quickly realize that the luggage is poorly positioned and may prevent the proper closure of the opening 22. The user can then also estimate the extent to which the luggage protrudes.

[0041] The calculation of the location of point A is calculated according to the shape of the opening 22, the lower part 25 being able to be inclined outwards and thus allow a suitcase located above to overhang towards the rear in relation to a suitcase located below.

[0042] As shown in [Fig.3], the first and second lighting means El and E2 are located on the trim element 34 of the upper band 260. They are then each located at one end of the band 260, their beams Fl and F2 then converging towards each other downwards, so as to intersect at the point of intersection A.

[0043] This second embodiment makes it possible to limit the diversity of parts by modifying only one element of the covering.

[0044] As shown in [Fig.4], according to a third embodiment, the first and second lighting means El and E2 are located on a trim element 37 of the rear edge 140 of the roof 14.

[0045] As in the second embodiment, they are then each located at one end of the rear edge 140 of the pavilion, their beams Fl and F2 then converging towards each other downwards, so as to intersect at the point of intersection A.

[0046] As shown in [Fig. 5], according to a fourth embodiment, the loading aid device 32 comprises the first and second lighting means E1 and E2 carried by the roof trim element 37 as described in the second embodiment, but also a third lighting means E3 carried by a central area of ​​the threshold bar 21, near a lock element, for example. The lighting means E3 emits a beam F3 directed vertically upwards.

[0047] The three beams Fl, F2 and F3 then converge at the point of intersection A.

[0048] As shown in [Fig. 6] to 8, the lighting means E1, E2 and E3 are described in more detail.

[0049] According to a first embodiment, the lighting means El, E2 and E3 are laser pointers formed of a cylindrical tip 40, containing a light source 42. A first end 44 of the tip 40 is connected to electrical power supply means 46 while the light beams Fl, F2, F3 are emitted by the opposite end 48 of the tip 40.

[0050] The tip 40 is disposed in an orifice 50 provided in the trim element 34, 36, 37 by means of a cylindrical ring 52 having a central hole 54 suitable for receiving the tip 40 and a peripheral groove 56 suitable for receiving the edges of the orifice 50.

[0051] In order to allow the beam Fl, F2, F3 to be oriented according to the desired angle, it may be provided, as shown in a first variant of [Fig.7], that the ring 52 is asymmetrical and has an inclined axis so that the tip 40 is inclined once inserted into the central hole 54.

[0052] It can also be provided, as shown in a second variant of [Fig.8], that the plane of the area of ​​the trim element in which the orifice 50 is provided is inclined so that the ring 52 is inclined once it is placed in the orifice 50. Thus, the tip 40, once inserted into the ring 52, is also inclined.

[0053] As shown in figures 9 and 10, the lighting means El, E2 and E3 can be, according to a second embodiment, a single light source 58, glued by means of a base 60, on a non-visible reverse face 62 of the covering element 34, 36, 37 and connected to an optical fiber 64 allowing the light emitted by the light source 58 to be diffused. A Y-connector 66 allows the fiber 64 to be divided into two secondary fibers 64A and 64B.

[0054] In the case where there are several means of lighting El, E2, E3 there would be a connection allowing to connect three secondary fibers.

[0055] The ends 640A and 640B of the fibers 64A and 64B each have an end fitting 68A and 68B.

[0056] The cover element 34, 36, 37 has an opening 69A, 69B suitable for receiving a frustoconical rubber cap 70A, 70B fixed by clipping by means of a support element 72A, 72B. The rubber cap 70A, 70B has on one of its lateral faces an opening 74A, 74B into which is inserted a rubber ring 76A, 76B suitable for receiving the end piece 68A, 68B.

[0057] The arrangement according to the invention thus makes it easy to fill a trunk by allowing a very quick visual assessment of whether luggage is likely to obstruct the closing of the trunk door.
