[0007] The invention also relates to a passenger compartment element comprising at least one device according to the invention, the device being fixed to the passenger compartment element or made of material with the passenger compartment element.

[0008] The invention further relates to an accessory designed to form an assembly with a device according to the invention or with a cabin element according to the invention, the accessory comprising a complementary interface projecting from the accessory and designed to be introduced by complementary shape into the opening of the housing of a fastening device along an introduction axis and to form a bayonet fastening of the accessory with the device by rotation of the complementary interface in the housing around the introduction axis.

[0009] The invention also relates to an assembly comprising at least one fastening device according to the invention or one cabin element according to the invention and at least one accessory according to the invention, each complementary interface being introduced into a fastening interface of a device.

[0010] The invention finally relates to a motor vehicle having at least one assembly according to the invention and / or at least one fastening device according to the invention.

[0011] Thus, the device according to the invention and the accessory, thanks to the mounting and complementary interfaces, allow for a reliable and easy-to-implement bayonet attachment. In the absence of an accessory attached to the device, the mounting interface, housed in a recess, prevents the risk of injury in the event of an impact. Finally, as explained below, a possible feature of the device allows for an electrical connection to be established between the accessory and the device to power the accessory without the need for an external cable.

[0012] According to one embodiment of the device according to the invention, the housing includes connection means designed to allow the transmission of electrical energy to a complementary interface introduced into the fixing interface.

[0013] Advantageously, the connection means comprise a plurality of electrical contacts.

[0014] According to one possibility, the device includes a plate mounted movable in the housing between a closed position in which the plate closes the housing and a retracted position in which the plate allows the introduction of a complementary interface into the opening.

[0015] Advantageously, the plate moves from its closed position to its retracted position by a translation along the insertion axis.

[0016] According to one possibility of the accessory, the complementary interface comprises a plurality of electrical contacts.

[0017] The invention will be better understood upon reading the following detailed description, given solely by way of non-limiting example and made with reference to the accompanying drawings in which:

[0018] [Fig-1] [Fig.1] represents an exploded view of a device according to the invention and of a accessory according to the invention designed to form an assembly according to the invention;

[0019] [Fig.2] [Fig.2] represents a partial view of the housing of the device;

[0020] In these figures, the same reference numerals are used to designate the same elements.

[0021] A fastening device 1 according to the invention, illustrated in exploded view in Figure 1, is designed for use in a motor vehicle. The device 1 is designed to allow the attachment of an accessory 2 according to the invention, illustrated in Figure 1, to a vehicle interior component (not shown), forming an assembly according to the invention. The interior component is, for example, a dashboard or a seat back.

[0022] The device 1 is designed to be attached to the passenger compartment component. To this end, the device 1 includes fastening means designed to attach the device 1 to the passenger compartment component. Such fastening means are, for example, an adhesive surface and / or at least one clip tab. Alternatively, the device 1 is formed from the material of the passenger compartment component.

[0023] The device 1 comprises a fixing interface 3 forming a housing 4 having an opening 5 delimited by a predetermined contour 6. In the example illustrated in [Fig. 1], the contour 6 forms a chevron.

[0024] As illustrated in [Fig. 2], the housing 4 is designed to allow the introduction of a complementary interface 7 of the accessory 2, having a shape complementary to the contour 6, along an insertion axis AI and to allow rotation of the complementary interface 7, introduced into the opening 5, around the axis The introduction AI is used to form, when the complementary interface 7 is inserted into the fixing interface 3, an assembly with a bayonet fixing of the accessory 2 with the device 1. As illustrated in [Fig. 1], the fixing interface 3 forms two chevrons inscribed in the contour 6. To form the bayonet fixing, the complementary interface 7 must be rotated around the introduction axis AI in the housing 4.

[0025] To form the bayonet fitting, the housing 4 has a space 8, illustrated in [Fig. 2], shaped to accommodate at least part of the complementary interface 7 inserted into the opening 5 and rotated about the insertion axis AI. As illustrated in [Fig. 2], the device 1 includes in the housing 4 a stop 9 designed to prevent the rotation of the complementary interface 7 about the insertion axis AI.

[0026] As illustrated in [Fig. 1], the device 1 comprises a plate 10 movably mounted in the housing 4 between a closed position, in which the plate closes the housing 4, and a retracted position, in which the plate 10 allows the insertion of a complementary interface 7 into the opening 5. In the example described, in the closed position, the plate 10 bears against an internal wall 11, illustrated in [Fig. 2], of the housing 4 in which the opening 5 is provided. The plate 10 is advantageously held in the closed position by elastic return means such as at least one spring 12. The plate 10 moves, for example, from its closed position to its retracted position by a translation along the insertion axis AI.Thus, when the complementary interface 7 is introduced into the opening 5 along the introduction axis AI, the complementary interface 7 exerts pressure on the plate 10, allowing it to move into its retracted position.

[0027] In the embodiment illustrated in the figures, the housing 4 includes connection means, not shown, designed to allow the transmission of electrical energy to the complementary interface 7 inserted into the mounting interface 3. Advantageously, the connection means comprise a plurality of electrical contacts, not shown. The accessory 2 advantageously comprises, on its complementary interface 7, a plurality of electrical contacts, also not shown. The electrical contacts of the complementary interface 7 are, for example, each arranged on a surface located between the two chevrons so as to prevent unintentional contact with a user's finger.

[0028] Thus, the device 1 and the accessory 2, thanks to the fastening interfaces 3 and complementary interface 7, make it possible to form a reliable and easy-to-implement bayonet fastening. In the absence of accessory 2 fixed to the device 1, the fastening interface 3, Positioned in housing 4, it helps prevent injury in case of impact. Finally, device 1 creates an electrical connection between accessory 2 and device 1 to power accessory 2 without the need for an external cable.

[0029] The invention is not limited to the embodiments of the device or accessory described above, only by way of example, but other embodiments may be designed by a person skilled in the art without departing from the scope and extent of the present invention.
