Definitions

• the invention relates to a motor vehicle accessory, which, when in position mounted in an opening in a given support, has a surface having an outer face oriented towards the passenger compartment of the vehicle and an inner face. bearing a technical function of the accessory.
• Publication GB-A-2264173 discloses an element for receiving an instrument fixed on a support by a bayonet type mounting.
• this type of attachment has drawbacks.
• the accessibility to this support varies from one vehicle to another.
• the fixing means as there are mounting types, which would considerably increase the mounting, manufacturing, or even logistics.
• the invention relates to an accessory compatible with two types of mounting.
• the invention also relates to an accessory whose assembly is simple and quick.
• the invention also relates to an accessory whose assembly is inexpensive.
• the subject of the invention is also an accessory, the attachment of which is possible in two mounting directions while keeping the same functional orientation.
• the invention provides an accessory of the type mentioned above, characterized in that the accessory comprises two fixing means of different type, one of the fixing means being used when the direction of introduction of the accessory in the given support is directed towards the passenger compartment and the other fixing means being used when the direction of introduction of the accessory into the given support is directed from the passenger compartment.
• the first attachment means is provided for bayonet mounting of the accessory.
• the first attachment means consists of two tabs, located in the extension of the surface, which: • in a first step, are inserted in the direction of the passenger compartment, along an X axis perpendicular to the plane of the support, in notches complementary formed in an edge of the opening until an external face of the legs rests on retaining elements carried by the support, • and in a second step, perform a rotational movement around the axis X, an internal face of the legs cooperating with an external part of the edge of the opening of the support, and the external face of the accessory cooperating with the retaining elements, until the legs are locked, in the mounted position, by at least one stop.
• the coding means consists of a difference in size between the two legs.
• the second fixing means is provided for snap-on mounting of the accessory.
• the second attachment means is formed of at least two blades perpendicular to the surface which, when inserting, from the passenger compartment, the accessory into the opening along an axis X perpendicular to the plane of the support, elastically deform, under the action of the edge of the opening until said edge is retained in a notch.
• the blades are carried by the internal face of the legs and in that the notch is formed between the blade and the internal face of the legs.
• FIG. 1 is a schematic side view of an accessory according to the invention.
• Figure 2 is a schematic top view of the accessory of Figure 1.
• FIG. 3 is a schematic view from below of the accessory of Figure 1.
• FIG. 4 is a schematic view from above of the accessory, fixed on a support according to a first mounting method, the accessory being in a first position.
• FIG. 5 is a schematic top view of the accessory, fixed according to the assembly mode of Figure 4, the accessory being in a second position.
• FIG. 6 is a schematic side view of the accessory, fixed on a support according to a second mounting method.
• an accessory 10 such as a loudspeaker, for example, has a substantially flat surface 12 comprising two faces 14 and 16.
• the other face 16 of the accessory 10 carries a means 20 for receiving a technical function of the accessory.
• the accessory 10 has a first fastening means 22 consisting of two tabs 24 which extend opposite one another and which extend the surface 12 of the accessory 10 .
• a second fastening means 26 consists of at least one elastic blade 28 oriented perpendicular to the surface 12 of the accessory 10, which is carried by a face 30 called “internal" legs 24.
• two elastic blades are shown distributed on either side of the accessory. The thickness of each blade 28 increases from its free end 32, so as to form a ramp 34, then decreases by forming an inclined face 35 so as to provide a notch 36 between the tab 24 and said ramp 34.
• the accessory 10 can be fixed on a support 38, such as a dashboard or a covering element, for example.
• the mounting method of the accessory 10 is different depending on the support 38 on which the accessory 10 must be mounted, in particular, depending on the way of accessing the support 38 or according to the configuration of the support which differs from a vehicle. to the other.
• the accessory 10 is fixed on the support 38 according to a first bayonet type assembly method using the first means of mounting 22.
• the bayonet mounting is then carried out in two stages.
• the tabs 24 are inserted in the direction of the axis X, in the direction of the passenger compartment 18, in complementary notches 44 formed in an edge 46 of the opening 40, until a external face 48 of the tabs 24 comes into contact with retaining means 50 carried by the support 38.
• the accessory 10 includes polarizing means.
• the tabs 24 are of different widths, which makes it easy to blindly insert the accessory 10 inside the opening 40, without risk of error.
• a pivoting of the accessory is applied around the axis X, the internal face 30 of the tabs 24 sliding along the external part 52 of the edge 46 of the opening 40 and the outer face 14 of the accessory 10 cooperating with the retaining means 50.
• Stops 54 are produced in the support 38.
• the notch 36 is shaped so that the edge 46 slides inside said notch 36 so that the accessory 10 can pivot without difficulty inside the opening 40.
• a non-return means (not shown) can be provided preventing the accessory 10 from turning in the other direction and come off.
• the accessory 10 is fixed according to a second snap-on mounting mode, using the second fixing means.
• the configuration of the opening 40 is then different from that described above.
• the edge 46 of the opening 40 is continuous and does not have the notches 44.
• the support 38 does not include the retaining means 50.
• the accessory 10 is inserted along the axis X inside the opening 40, from the passenger compartment 18.
• the elastic blades 28 are deformed under the effect of contact between the ramp 34 and the edge 46 of the opening 40, until, after the passage of the inclined face 35, the edge 46 of the opening 40 is retained in the notch 36.
• Guide means 56 of the accessory 10 can be provided along the edge 46 so as to facilitate the insertion of the accessory 10 into the opening 40.
• the second fastening means is carried by the tabs 24, which simplifies the part 10. Notches (not shown) can be made in the blades 28 on either side of the fasteners 26 to increase their flexibility.
• one or other of the mounting methods can be used without difficulty depending on the support given.
• the accessory 10 according to the invention thus has the advantage of being able to be compatible with different supports, which can lead to a reduction in costs since a single piece is produced for several different supports. In addition, it also simplifies assembly and logistics.
