Description

s À r "Arrangement of the rear part of a motor vehicle comprising

  a box for storing a spare wheel "The invention relates to an arrangement of the rear part of a motor vehicle for storing a spare wheel

vehicle rescue.

  The invention relates more particularly to an arrangement of the rear part of the passenger compartment of a motor vehicle which is delimited by at least one opening disposed transversely and vertically at the rear of the passenger compartment, and which comprises, close to the rear end of the passenger compartment, a box which delimits a confined closed volume designed to receive a spare tire of the vehicle in transverse and vertical position and at least one wall of which is formed by an internal face of the opening

closed position of the latter.

  Current vehicles of the "all-terrain" or "4 x 4" type are designed both for urban use and for use on rough roads. On many vehicles of this type, the spare wheel is fixed on a support

outside the vehicle.

  This arrangement makes it possible to make the spare wheel more accessible in the event of a puncture and to free up the space inside the vehicle in which the rear luggage compartment, capable of receiving the spare wheel, is a rear part: s the cockpit. However, according to this conception, the spare tire is exposed to external aggressions coming from

  bad weather, but also acts of vandalism.

  To protect the spare wheel, it has been proposed in document FR-A2.806.057 to fix the spare wheel on a support which is carried by the frame of the leaf, and to cover

  the whole by covering panels of the vehicle.

  Although this arrangement makes it possible to protect the spare tire from the outside, it does not allow easy access to the spare tire. Indeed, for the dismantling of the spare wheel, I F must first dismantle an access hatch to the fixing screws of the spare wheel with the support, then it is necessary to dismount a

  second panel to be able to remove the spare wheel.

  11 has also been proposed to accommodate the spare wheel inside a luggage compartment of the vehicle, along the

  floor or along a side wall of the compartment.

  However, for certain vehicles, the depth of the compartment is less than the outside diameter of the wheel, by

  so this solution is not feasible.

  o To remedy these drawbacks, the invention aims to propose an arrangement of the type described in the introduction, characterized in that it comprises a flange which is mounted articulated between a closed position in which the box is closed, and a open position allowing access to the interior volume of the box, for the introduction or extraction of the spare wheel. According to other characteristics of the invention: the housing belongs to the opening; - the flights provide access to the interior volume of the box or by opening an opening formed in a transverse rear face of the box; - The box is fitted inside the passenger compartment, and in that the flaps are formed by a portion of the opening; - The box is delimited by a lower partition formed by the floor and it comprises two vertical lateral partitions, a horizontal upper partition, and a vertical and transverse front partition; - The box is made in the form of a removable soul-assembly which is capable of being dismantled when the vehicle so does not carry a spare wheel; - The floor and / or at least one side wall of the passenger compartment include a housing in which the partitions of the box can be stored when the vehicle is not transporting the spare wheel; - The front transverse partition comprises at least two transverse panels which are hinged together and which can be arranged, in particular by superimposing one on the other, inside a housing; - the spare wheel is carried by the door. Other features and advantages of the invention

  o FIGS. 1 and 2 show a motor vehicle of the "all terrain" type which comprises a luggage compartment 22, or trunk, which forms the rear part of the passenger compartment of the vehicle 20. The luggage compartment 22 is delimited by a horizontal floor 24, two opposite longitudinal side walls 26d right and 26g left, and an opening 27 arranged transversely and vertically at the rear of the compartment a

luggage 22.

  The opening 27 comprises a door 28 which is mounted articulated with respect to the body structure of the vehicle 20 o around a vertical axis A arranged at the rear end of the wall

  left 26g of the luggage compartment 22.

  The door 28 is surmounted by a window 30 which is slidably mounted vertically, relative to the door 28, between a high position in which the rear face 62 of the luggage compartment 22 is entirely closed by the door 28 and the window 30, and a low position (not shown) in which the window 30 is retracted inside the door 28 so that the door 28 only closes part of the rear face 62 of the luggage compartment 22 is closed when the door 28 is in the closed position. Thus, when the window 30 is in the low position, it is possible to access the interior volume of the luggage compartment 22, without having to manipulate the door 28 which is often

heavy and bulky.

  As shown in Figures 3 and 4, the lower part of the door 28 comprises a box 32 which delimits a closed volume 34 con, cu to accommodate a spare wheel 36 of the

motor vehicle 20.

  When it is stored in the box 32, the spare wheel 36 is in a transverse and vertical position, that is to say with its axis of rotation B parallel to the general longitudinal axis

vehicle 20.

  The spare wheel 36 is fixed on an internal wall 38 of the door 28, which constitutes a wall of the box 32, and it is fixed on this internal wall 38 by means of means similar to those used for fixing it on a hub of an axle (not shown) of vehicle 20, which here consist of

screw 40.

  s In accordance with the invention, the box 32 comprises a flies 42 which is mounted articulated with respect to the upper end 29 of the internal wall 38 around a transverse axis C, and which allows access to the internal volume 34 of the box 32. The flights 42 is movable between a low closed position in which the box 32 is completely closed, and a high open position, shown in silhouette in FIG. 3, in which it allows access to the interior volume 34 of the box, for

  ['introduction or extraction of the spare wheel 36.

  In vertical longitudinal section, the voles 42 has the shape s of an "L" returns whose horizontal branch 44 forms the horizontal upper wall of the box 32, and its free end 46 is articulated relative to the upper end 29 of the internal wall 38 around the axis C. The vertical branch 48 of the flights 42 extends transversely towards the teas from the horizontal branch 44, and its free lower end 50 comprises locking means not shown on the flights 42 in the basset position The voles 42 is disposed at the rear of the spare wheel 36, so that it releases an opening formed in a rear transverse face of the box 32 when it is in the high opening position. Thus, the opening of the box 32 is independent of the opening of the luggage compartment 22, which is particularly advantageous since it is not necessary to manipulate the door 28 to access the interior volume 34 of the

  box when you want to access the spare tire 36.

  In addition, when the spare wheel 36 is absent, the box 32 offers a storage space which can receive o objects and which protects them from the outside, even when the window 30 is in the basset position. According to another embodiment of the invention represented in FIGS. 5 to 12, the box 32 is fitted inside the luggage compartment 22, so that it stetends vertically upwards from the rear end 52 of the floor 24, which then constitutes the partition lower which delimits

box 32.

  The box 32 also has two opposite longitudinal side partitions 54d, 54g, an upper partition

  o horizontal 56, and a vertical transverse bulkhead 58.

  In accordance with the invention, the rear vertical transverse face 60 of the box 32 is closed by a movable flight constitutes

through a portion of door 28.

  According to this embodiment of the invention, the spare wheel is also in a vertical transverse position in the

interior volume 34 of box 32.

  The vehicle 20 is of the "all terrain" type, which generally implies that the outside diameter of the spare wheel 36 is relatively large. As a result, the box 32 obstructs a large part of the rear face 62 of the compartment a

luggage 22.

  So that it is possible to access the baggage compartment 22 by its rear face 62, the box 32 is attached to the left side wall 26g of the baggage compartment 22, so that the left side wall 54g is formed by a portion from the left side wall 26g of the baggage compartment 22. As shown in FIGS. 5 and 6, a narrow space is thus cleared between the right side wall 54d of the box 32 and the right side wall 26d of the baggage compartment 22 , which gives access to the interior volume of the

luggage compartment 22.

  The spare wheel 36 is fixed to an internal face 64 of the door 28 by means of screws 40. For this purpose, as shown in FIG. 7, the internal face 64 of the door 28 comprises a metal plate 66 which is carried by the internal frame (not shown) of the door 28, and which includes tap holes 68, here four in number, which re-paste the screws

  spare wheel attachment 36.

  The box 32 thus makes it possible to isolate the various objects placed inside the luggage compartment 22 of the spare wheel 36 which is sometimes dirty, in particular when used

"all-terrain" vehicle 20.

  In addition, as in the case of the first embodiment, and when the door 28 is in the closed position, the interior volume 34 of the box 32 is always closed, even when the window 30 is in the low position, so as to isolate the spare tire from the outside, or the various objects that the box 32 can contain. s When the vehicle 20 does not carry the spare wheel 36, the box 32 is sometimes unused and it can even be inconvenient when it is desired to load bulky objects at

  inside the luggage compartment 22.

  To this end, and according to another aspect of the invention, the box 32 is produced in the form of a removable element which is capable of being removed in the absence of the spare wheel 36. In addition, the floor 24 and the left side wall 26g each have a housing 72, 74 in which the demounted partitions of the box can be stored. The bottom 80 of the housing 72 of the floor then constitutes the lower partition of the box 32, and the bottom 82 of the housing 74 of the side wall

  left 26g constitutes ia left side wall 54g of the box.

  For the dismantling of the box 32, the right side partition 54d, the upper partition 56 and the front transverse partition 58 are demountably interconnected, here by means of pins 70, and they are articulated with respect to

  to the floor 24 and the left side wall 26g.

  o Thus, the left end 76 of the upper wall 56 is articulated with respect to the upper end 74s of the housing 74 of the left side wall 26g around a longitudinal axis D, and the upper wall 56 is movable between a position deployed in which it extends horizontally to form the box s 32, and a low position, represented in FIGS. 9 and 10, in

  which it extends vertically in the housing 74.

  The right lateral partition 54d is articulated at its lower end 78 relative to the right end 72d of the housing 72 around a longitudinal axis E, and it is movable between a deployed position in which it extends vertically towards the high from the floor 24 to form the box 32, and a low position, represented in FIGS. 9 and, in which it extends horizontally in the housing

72 from floor 24.

  The front transverse partition 58 is articulated at its lower end 84 relative to the front longitudinal end 80a of the bottom 80 of the housing 72, around a transverse axis F. between a deployed position in which it extends vertically towards the top from the bottom 80 of the housing 72 to form the box 32, and a low position represented in FIG. 9, in which it extends horizontally in the

floor 72 housing 24.

  The box 32 has the shape of a parallelepiped, the height "h" and the transverse width of which is substantially equal to the diameter of the spare wheel 36, and the longitudinal depth "p" of which is equal to the thickness of the spare wheel 36, and therefore less than the height "h" and the width, e, '

box 32.

  s As a result, the bottoms 80 and 82 of the housings 72 and 74, the upper partition 56 and the right lateral partition 54d, wind rectangles of length equal to the height "h" and to the width, e ,, of the box 32 , and of width equal to the depth "p" of the box 32. o The transverse front partition 58 is a square whose length of the sides is equal to the height "h" and to the width ', e,' of the box 32. Thus, when it is folded in the housing 72, it extends longitudinally towards the rear beyond the end

rear of bottom 80 of housing 72.

  This is why the front transverse partition 58 comprises several panels 86, here four in number, which are articulated between them and whose height "m" of each panel 86 is

  substantially equal to the depth "p" of the box 32.

  As shown in FIG. 9, when the front transverse partition 58 is folded, the panels 86 are superimposed on one another so as to be stored at

  the interior of the housing 72 of the floor 24.

  For the dismantling of the box 32, as shown in FIG. 8, the partitions are first of all separated from one another by removing the pins 70. Next, the upper partition 56 is folded back into the housing 74 of the wall 26g left side, and the 86 wind panels folded over each other

  others in the housing 72 of the floor 24.

  When the panels 86 wind in the housing 72, as shown in FIG. 9, the right lateral partition 54d is provided for being folded back in the housing 72 by covering the

panels 86.

  As shown in Figure 10 the right side wall 54d is folded over the panels 86 so that its upper face 88 is flush with the upper face 24s of the floor 24. Likewise, the upper face 56s of the upper partition 56

  is flush with the internal face 90 of the right side wall 26d.

  Thus, when the box 32 is dismounted, it is possible to use the maximum loading capacity of the luggage compartment 22, without the partitions of the box 32, nor the housings 72 and 74 interfering with the loading or unloading.

luggage compartment 22.

  Since the housing 72 of the floor 24 receives the right lateral partition 54d and the panels 86, the bottom 80 of the housing 72 is situated at a height lower than that of the upper face 24s of the floor 24. When the vehicle 20 transports the spare wheel 36, as shown in FIG. 5, the lower portion

  of the spare wheel 36 is located below the floor 24.

  The fact of lowering the height of the spare wheel 36 makes it possible to improve the visibility towards the rear from the driving posse, which is particularly advantageous during maneuvers. According to a variant of the invention, represented in FIG. 11, the box 32 is centered transversely in the luggage compartment 22, and therefore the spare wheel 36 is also centered transversely, ie its axis of rotation C extends in the median longitudinal plane of the vehicle 20. The left side wall 54g of the box 32 is then no longer formed by the left side wall 26g of the compartment

  baggage 22, and then it stretches away from behind.

  Therefore, when the box 32 is removed, the left side wall 54g and the upper wall 56 are re cues in the housing 72 of the floor 24 and the left side wall 26g

  therefore has no accommodation to receive them.

  Whether it is one or the other of the two embodiments

  of the invention, it is possible to arrange the box 32 so that the wheel is centered transversely relative to the motor vehicle 20. This configuration makes it possible to have a particular shape of the door 28 shown in FIGS. 1 and 2 in which the lower corners 94 of the window 30 descend more teas

  than the central part of the lower bard 96 thereof.

  This makes it possible to improve the field of vision at the rear of the vehicle 20, which is particularly appreciated during maneuvers.
