Description

Title of the invention: arrangement of a device for assisting 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 backs 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 which is mounted a glazed panel, the upper transverse strip of the frame being rotatably mounted around a rear edge of a roof of the vehicle and a lower part of which a lower edge comes to rest in the vicinity of the floor in the closed position.

[0002] It is often difficult for users loading their trunk to visually estimate whether the door will close easily without being hindered by the contents, such as luggage for example. The user must then place the luggage in the trunk, close the door to check that it closes, then reopen it if necessary and modify the arrangement of the luggage. The user must then repeat these operations as many times as necessary until satisfactory loading is obtained.

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

[0004] To this end, the invention proposes an arrangement of the type cited above, characterized in that the opening comprises at least two lighting means each capable of emitting 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 part and the lower part of the opening in the closed position.

[0005] According to other characteristics of the invention:

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

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

[0008] First and second lighting means are carried by a trim element of the edge of the roof.

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

[0010] The lighting means are laser pointers capable of being received in orifices 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 covering element.

[0012] The orientation of the beam 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 orifices provided in the cladding elements.

[0014] The light source is a laser generator arranged on the back of the covering element, the fibers are glued to the back of the covering element and open into supports arranged in orifices.

[0015] Other characteristics and advantages of the invention will appear on reading the description of exemplary embodiments of a conduit with reference to the appended drawings in which:

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

[0025] [Fig. 10] [Fig. 10] is a schematic sectional view of a detail of the embodiment of [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 similar elements are designated by the same reference numerals.

[0028] With the exception of the specific elements of the driving position, the vehicle has a general symmetry with respect to a median longitudinal plane.

[0029] As described in Figures 1 to 10, a vehicle 10 comprises 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 comprises a threshold 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 which is arranged a glazed panel 28. The frame 26 has an upper horizontal strip 260, a lower strip 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 zone 27.

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

[0034] Thus the opening 22 is mounted to rotate around a closed position in which it closes the loading zone 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, luggage 30 is arranged inside the trunk 12.

[0036] In order to prevent this luggage from preventing the opening 22 from closing, a device 32 is provided to assist in loading the trunk.

[0037] The loading assistance device 32 comprises at least two lighting means E1 and E2 each emitting a light beam F1 and F2 in the visible light spectrum.

[0038] In the first embodiment described in [Fig.2], the first lighting means E1 is carried by an interior trim element 34 of the upper strip 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 F1 emitted by the first lighting means E1 is directed downwards and towards the outside of the vehicle, out of the trunk 12, while the beam F2 of the second lighting means E2 is directed downwards and towards the inside of the trunk 12. Thus, the beams F1 and F2 intersect at a point A, located in space at a point corresponding to the junction zone 27 of the opening 22 when the opening 22 is closed.

[0040] Thus, when a user places luggage inside the trunk 12, if he observes the projection of a first point PI and the projection of a second point P2 on the luggage, this means that the intersection point A is located at the location of the luggage. The user can therefore quickly realize that the luggage is incorrectly positioned and risks preventing the correct closing of the opening 22. The user can then also estimate the extent of the luggage overhang.

[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 allowing a suitcase located above to protrude backwards relative to a suitcase located below.

[0042] As shown in [Fig. 3], the first and second lighting means E1 and E2 are located on the covering element 34 of the upper strip 260. They are then each located at one end of the strip 260, their beams F1 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 the parts by modifying only one covering element.

[0044] As shown in [Fig.4], according to a third embodiment, the first and second lighting means E1 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 roof, their beams F1 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 assistance 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 zone of the threshold bar 21, in the vicinity of a lock element, for example. The lighting means E3 emits a beam F3 directed vertically upwards.

[0047] The three beams F1, F2 and F3 then converge at the intersection point 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 E1, E2 and E3 are laser pointers formed from a cylindrical end piece 40, containing a light source 42. A first end 44 of the end piece 40 is connected to electrical power supply means 46 while the light beams F1, F2, F3 are emitted by the opposite end 48 of the end piece 40.

[0050] The end piece 40 is arranged in an orifice 50 formed in the covering element 34, 36, 37 by means of a cylindrical ring 52 comprising a central hole 54 capable of receiving the end piece 40 and a peripheral groove 56 capable of receiving the edges of the orifice 50.

[0051] In order to allow the beam F1, 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 end piece 40 is inclined once inserted into the central hole 54.

[0052] It may also be provided, as shown in a second variant of [Fig.8], that the plane of the area of ​​the covering element in which the orifice 50 is provided is inclined so that the ring 52 is inclined once arranged in the orifice 50. Thus, the end piece 40, once inserted in the ring 52, is also inclined.

[0053] As shown in Figures 9 and 10, the lighting means E1, E2 and E3 may 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 making it possible to diffuse the light emitted by the light source 58. A Y-shaped connector 66 makes it possible to divide the fiber 64 into two secondary fibers 64A and 64B.

[0054] In the case where there are several lighting means E1, E2, E3 there would be a connection allowing three secondary fibers to be connected.

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

[0056] The covering element 34, 36, 37 has an orifice 69A, 69B capable of receiving a rubber cap 70A, 70B of truncated cone shape 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 in which is inserted a rubber ring 76A, 76B capable of receiving the end piece 68A, 68B.

[0057] The arrangement according to the invention thus makes it possible to simply facilitate the filling of a trunk by making it possible to visually estimate very quickly whether a piece of luggage risks hindering the closing of the trunk door.
