Description Title of the invention: Device for fixing a passenger compartment accessory.
[0001] The present invention claims priority from French application 2408548 filed on August 1, 2024, the content of which (text, drawings, and claims) is incorporated herein by reference. The technical field relates to fastening devices designed to allow the attachment of an accessory to a passenger compartment component, passenger compartment components comprising at least one such device, assemblies comprising such a device and an accessory attached to the device, and finally, motor vehicles having such assemblies and / or such passenger compartment components.
[0002] Car manufacturers take great care in developing their vehicles to offer customers vehicles with impeccable build quality. This build quality is primarily reflected in the quality of the assembly and materials used in the vehicle. However, the perceived quality is also influenced by the quality of the accessories supplied with the vehicle and the available mounting options. Car manufacturers therefore offer mounting solutions for accessories fitted at the factory or available through aftermarket services. However, these solutions often offer limited mounting options, are unreliable, and / or pose a risk of injury in the event of a head collision with a vehicle passenger.Furthermore, attaching an accessory to an interior component such as a dashboard and / or seat back often requires an external electrical connection cable to power the accessory. These external electrical cables clutter the interior and detract from its aesthetics.
[0003] Finally, car manufacturers are particularly attentive to the safety of drivers and passengers in their vehicles. In this context, it is important that the solutions implemented for attaching accessories do not contain any features that could cause injury in the event of a collision with the head of the driver or a passenger.
[0004] Therefore, there is a need for a solution that allows for the simple and reliable attachment of accessories to a passenger compartment component while preserving the aesthetics and safety of the passenger compartment. There is also a need for a A solution that allows an accessory to be powered without the need for an external power cable.
[0005] The present invention aims to overcome the problems described above. In this technical context, one objective of the present invention is to provide a fastening device for reliably and easily attaching an accessory. Another objective of the invention is to provide an accessory compatible with the device. Finally, another objective of the invention is to provide a power supply to the accessory when it is attached to the device.
[0006] To this end, the present invention relates to a fastening device for a motor vehicle, designed to allow the attachment of an accessory to a passenger compartment element of the vehicle, the device being designed to be secured to the passenger compartment element, the device comprising a fastening interface forming a housing having an opening delimited by a predetermined contour, the housing being designed to allow the introduction of a complementary interface of the accessory having a shape complementary to the contour along an axis of introduction and to allow a rotation of the complementary interface introduced into the opening around the axis of introduction to form, when the complementary interface is introduced into the fastening interface, an assembly having a bayonet fastening of the accessory with the device.
[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 interior component according to the invention and at least one accessory according to the invention, each complementary interface being introduced into a device attachment interface.
[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 case of impact. Finally, as explained below, a 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 means of connection include 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] Depending on one possibility of the accessory, the additional interface includes a plurality of electrical contacts.
[0017] The invention will be better understood upon reading the detailed description that follows, given solely by way of non-limiting example and made with reference to the accompanying drawings in which:
[0018] [Fig. 1] Figure 1 represents an exploded view of a device according to the invention and an accessory according to the invention designed to form an assembly according to the invention;
[0019] [Fig. 2] Figure 2 represents a partial view of the device housing;
[0020] In these figures, the same references are used to designate the same elements.
[0021] A fastening device 1 according to the invention, illustrated in the exploded view shown 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] Device 1 is designed to be attached to the passenger compartment component. To this end, device 1 includes fastening means designed to attach device 1 to the passenger compartment component. Such fastening means are, for example, an adhesive surface and / or at least one clip tab. Alternatively, 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 Figure 1, the contour 6 forms a chevron.
[0024] As illustrated in Figure 2, the housing 4 is designed to allow the insertion of a complementary interface 7 of the accessory 2, having a shape complementary to the contour 6, along an insertion axis A1, and to allow rotation of the complementary interface 7, inserted into the opening 5, around the insertion axis A1 to form, when the complementary interface 7 is inserted into the fastening interface 3, an assembly providing a bayonet fastening of the accessory 2 with the device 1. As illustrated in Figure 1, the fastening interface 3 forms two chevrons inscribed in the contour 6. To form the bayonet fastening, the complementary interface 7 must be rotated around the insertion axis A1 of the housing 4.
[0025] To form the bayonet fitting, the housing 4 has a space 8, illustrated in Figure 2, shaped to accommodate at least part of the complementary interface 7 inserted into the opening 5 and rotated about the insertion axis A1. As illustrated in Figure 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 A1. For example, the housing 4 and the stop 9 allow the complementary interface 7 to rotate a quarter turn within the housing 4.
[0026] As illustrated in Figure 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 Figure 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 A1.Thus, when the complementary interface 7 is introduced into the opening 5 along the introduction axis Al, the complementary interface 7 exerts pressure on the plate 10, allowing it to move to 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, device 1 and accessory 2, thanks to the mounting interfaces 3 and complementary interface 7, allow for a reliable and easy-to-use bayonet attachment. In the absence of accessory 2 attached to device 1, the mounting interface, located in housing 4, prevents the risk of injury in case of impact. Finally, device 1 allows for 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 devised by a person skilled in the art without departing from the scope and extent of the present invention.
