Description

Title of the invention: Vehicle with a modular seat that converts into a bed technical field

[0001] The present invention relates to the automotive field. In particular, the invention relates to a vehicle comprising a seat that can be converted into a bed. Technological background

[0002] For sleeping in a vehicle whose primary use is passenger transport, i.e., other than a motorhome or campervan, it is known to place a box above the trunk floor and rear seats on which a mattress can be placed. This solution, however, is relatively bulky and occupies a large part of the trunk space.

[0003] It is also known to position a mattress on the floor of the trunk and the back of the seat. Summary of the invention

[0004] There is a need for a vehicle that allows for modulation into a bed function, minimizing the loss of space while ensuring comfort for the user.

[0005] The present invention addresses this need by means of, according to one of its aspects, a vehicle comprising: - a chest including a floor; - a modular seat that converts into a bed, including: • a base; • a movable backrest relative to the seat between an upright position and a folded-down position, a front surface of the backrest being opposite a surface of the seat when the backrest is in the folded-down position, a rear surface of the backrest being opposite the trunk when the backrest is in the upright position, the front surface of the backrest and the surface of the seat being respectively intended to receive the back and buttocks of a user in a seated position on the seat; - a housing mounted movable relative to the trunk between a rear position, in which a bearing surface of the housing faces an upper surface of the trunk floor, and at least one front position, in which a contact surface of the housing, opposite the bearing surface of the housing, faces the rear surface of the backrest arranged in the folded position, - a movable support mounted on the housing between a folded position, in which a bearing surface of the support faces the bearing surface of the housing, and a position deployed, in which the support surface of the support extends in continuity with the support surface of the housing; the support surface of the support and the support surface of the housing forming a support frame to accommodate a user in a lying or semi-sitting position when the backrest is in the folded position, the housing is in the forward position and the support is in the deployed position.

[0006] Thanks to the use of the mobile support in relation to the backrest and the mobile-mounted housing in relation to the trunk, the vehicle seat according to the invention can be easily and quickly modulated into a bed function, while limiting the space occupied by the support and the mobile-mounted housing in relation to the trunk.

[0007] By "the support surface of the backrest extends in continuity with the rear surface of the backrest," it is meant that the junction between the two surfaces is continuous, without any break. In other words, when the backrest is in the deployed position, the two surfaces form a seamless surface.

[0008] The rear surface of the backrest can form a non-zero angle α with the horizontal when the backrest is in the folded position, in particular an angle α between 5° and 25°.

[0009] The bearing surface of the housing and the contact surface of the housing can form an angle substantially equal to the angle a so that the bearing surface of the housing extends in a substantially horizontal plane when the backrest is in the folded position and the housing is in the forward position.

[0010] The box may include a lower part and an upper part, the casing being mobile in rotation between the rear position and the front position around an axis of rotation of the casing in the lower part of the box.

[0011] The housing may include a proximal part and a distal part.

[0012] The support can be mobile in rotation between the folded position and the position deployed around a rotation axis of the support in the distal part of the housing.

[0013] The axis of rotation of the housing can be in the proximal part of the housing.

[0014] The housing can be mounted movably on two side walls of the box.

[0015] The trunk floor can be moved between a low position and a high position.

[0016] The bearing surface of the housing can face the upper surface of the floor when the case is in the rear position and the floor is in the lower position.

[0017] The upper surface of the floor can be configured to be in continuity with the support surface of the case when the backrest is in the folded position, the case is in the forward position and the floor is in the high position.

[0018] The support may include sleeves allowing the insertion of rods for a vehicle seat headrest.

[0019] The housing may include an open cavity in an upper part of the housing, in particular at the contact surface of the housing, preferably a plurality of open cavities at the contact surface of the housing, the open cavity forming a storage space when the housing is in the rear position.

[0020] The vehicle may include at least two seats, in particular at least one single seat and one two-seater seat.

[0021] The vehicle may include a mattress configured to be positioned at least on the support surface of the stand and on the support surface of the case when the backrest is in the folded position, the case is in the forward position and the stand is in the deployed position. Brief description of the figures

[0022] The following description, with reference to the accompanying drawings, given by way of non-limiting examples, will clearly explain what the invention consists of and how it can be implemented. In the accompanying figures:

[0023] [Fig-1] Fig. 1 illustrates, in side view, schematically, an example of vehicle according to the invention, in which the backrest is in the raised position, the housing is in the rear position, and the support is in the folded position;

[0024] [Fig.2] Fig.2 is a view similar to Fig.1 in which the file is in position folded down, that the case is in the forward position and that the support is in the deployed position. Description of method(s) of implementation

[0025] In the following description, identical elements or elements with identical functions bear the same reference numeral. For the sake of brevity, they are not described opposite each figure; only the differences between the embodiments are described.

[0026] In the figures, the actual proportions have not always been respected, for the sake of clarity.

[0027] Figures 1 and 2 illustrate an example of vehicle 1 according to the invention.

[0028] The vehicle 1 includes a passenger compartment 2 forming, in a rear part, a trunk 3.

[0029] The chest 3 includes a movable floor 4 between a low position ([Fig.1]), and a high position ([Fig.2]).

[0030] Vehicle 1 also includes front seats 5 and rear seats 6.

[0031] For example, one of the seats 6 comprises a single seat, the other comprises two seats.

[0032] Each seat 6 includes a seat 7 comprising a seating surface 8 configured to receive the buttocks of a user of the seat 6.

[0033] Each seat 6 also includes a backrest 9 comprising a front surface 10 intended to receive the back of a user.

[0034] The backrest 9 is mobile relative to the seat 7 between an upright position ([Fig.1]) and a folded-down position ([Fig.2]).

[0035] When the backrest 9 is in the folded position, the front surface 10 of the backrest 9 is opposite the seating surface 8, the two surfaces 8 and 10 forming an angle substantially zero between them.

[0036] When the backrest 9 is in the raised position, the front surface 10 of the backrest 9 and the seat surface 8 form an angle between 60° and 120°. In addition, a rear surface 11 of the backrest 9 is opposite the storage compartment 3.

[0037] The vehicle 1 also includes a housing 12 mounted movable relative to the trunk 3 between a rear position ([Fig. 1]), in which a bearing surface of the housing 13 faces an upper surface 14 of the floor 4, and a front position ([Fig. 2]), in which a contact surface of the housing 15, opposite the bearing surface of the housing 13, faces the rear surface 11 of the seat back 9 in the folded-down position. The fact that a part A "faces" a part B means that said part A may face part B directly or indirectly, that is, with or without an intermediate part between parts A and B. Thus, the bearing surface of the housing 13 faces the upper surface 14 of the floor 4, with the support 25 positioned between this bearing surface 14 and the support surface of the housing 13.

[0038] The housing 12 is mounted to rotate about an axis B extending between two lateral walls of the chest 3. The axis B is at the level of a lower part of the chest 3 and a proximal part 20 of the housing 12, opposite a distal part 21 of the housing 12. In the present invention, the distinction between the distal part 21 and the proximal part 20 is appreciated according to the proximity of the backrest 9 when the housing 12 is in the rear position.

[0039] The housing 12 is open at the contact surface of the housing 15. These openings 18 form storage compartments 19 which are accessible from the trunk 3 when the housing 12 is in the rear position. This can limit the loss of available volume in the trunk 3 when the housing 12 is in the rear position.

[0040] In addition, the bearing surface of the housing 13 and the contact surface of the housing 15 extend in planes forming between them a non-zero angle α, in particular an angle α between 5° and 25°.

[0041] This angle a is advantageously equal to the angle formed by the rear surface 11 and the horizontal when the backrest 9 is in the folded position. In this way, when the housing 12 is in the forward position, the support surface 13 forms a substantially zero angle with the horizontal.

[0042] The housing 12 preferably has a substantially triangular shape, when viewed in a plane perpendicular to the axis B, with the contact surface of the housing 15 complementary to the angle of inclination with respect to the horizontal of the rear surface 11 of the backrest 9. The housing 12 is preferably arranged so that the bearing surface of the housing 13 is substantially horizontal when the housing 12 is in the forward position.

[0043] The vehicle 1 also includes a support 25 movably mounted on the housing 12 between a folded position ([Fig.1]), in which a bearing surface of the support 26 faces the bearing surface of the housing 13, and a deployed position ([Fig.2]), in which the bearing surface of the support 26 extends in continuity with the bearing surface of the housing 13.

[0044] The support 25 is mounted for rotation on the housing 12 around an axis S in the distal part 21 of the housing 12.

[0045] The rotation axis S of the support 25 is advantageously parallel to the rotation axis B of the housing 12.

[0046] Thus, as illustrated on [Fig.2], when the backrest 9 is in the folded position, the housing 12 is in the forward position and the support 25 is in the deployed position, the bearing surface of the support 26 and the bearing surface of the housing 13 form a support frame to receive a user H in a lying or semi-seated position.

[0047] Advantageously, the floor 4 can be positioned in the high position when the backrest 9 is in the folded position, the housing 12 is in the forward position and the support 25 is in the deployed position.

[0048] The housing 12 may include, in the proximal part 20 at the level of the bearing surface of the housing 13, a notch 40 allowing to receive an edge 41 of the floor 4. This may allow the upper surface 14 of the floor 4 to be in continuity with the bearing surface of the housing 13.

[0049] When the support 25 is in the deployed position and the housing 12 is in the forward position, a portion 27 of the support can be in contact with the seating surface 8. This portion 27 allows the user's weight H to be supported at a distance from the axis S, which allows the use of an axis S having limited resistance to stress.

[0050] Furthermore, the support 25 may include sleeves 30 in a part opposite to the axis S. The sleeves 30 allow the insertion of rods 31 of a headrest 32 of one of the seats 5 and 6 of vehicle 1. The headrest 32 can thus be used as a support for the head of the user H.
