Definitions

• the invention relates to a method for mounting an air conditioning module on a structural cross member, a system for implementing this method, a dashboard of a vehicle incorporating an air conditioning module thus mounted and a vehicle thus equipped.
• a vehicle dashboard here relates to a unitary structure comprising the control and functionality means, which can also be designated by "cockpit", and located under the vehicle windshield and extending over the entire width of the vehicle .
• the invention applies in particular in the field of motor vehicles.
• the air conditioning modules are fixed either on the vehicle body or on the structural cross member of the dashboard. This fixing is carried out by means of screws, bolts, rivets or staples of which the number is suitable.
• the invention proposes to dispense with added fixing means by performing a pivoting assembly.
• the subject of the invention is a method for mounting an air conditioning module on a structural cross member consisting, in a first step, in assembling the module on the cross member by rotation, then rotating the module and, in a second step, detachably hooking a pivoting part of the module on the crosspiece.
• a system for mounting a longitudinal air conditioning module is also proposed on a cross member of a vehicle dashboard structure, comprising at least one spar integral with the air conditioning module perpendicular to its longitudinal direction, a support of the crossmember of complementary structure to receive said spar over a sufficient amplitude of pivoting, and of additional removable hooking means fixed on the module to be mounted and on the crossmember of structure.
• the longitudinal members of the module are two cylindrical elements symmetrical with respect to the longitudinal direction
• the support is semi-cylindrical and extends at the bottom of a groove disposed parallel to the cross member
• the hooking means are of the clipping type consisting of a male hook-shaped part, having a portion with elastic double blade terminated by a flared portion, as well as a female part whose opening allows forceful insertion of the hook.
• the hook can tilt against a restoring force and return to a locking position by the exercise of this force.
• the hook heads are made of elastomeric or rubber material, absorbing vibrations and parasitic noise.
• the invention also relates to a dashboard incorporating a structural cross member and the air conditioning module mounted on the cross member according to the system of the invention, as well as to the vehicle equipped with such a dash board.
• Figure 4 a side perspective view of the previous assembly after connection of the hooking means.
• Figure 1 illustrates the positioning of an air conditioning module 1 facing a cross 2 of dashboard before mounting the module.
• the air conditioning module 1 extends generally along a longitudinal direction D and comprises, according to the nonlimiting example illustrated, two coaxial cylindrical beams 10, arranged orthogonally and symmetrically with respect to this direction. These beams 10 spring outside the lateral flanks F of the module 1, so as to allow their insertion into a structure complementary to the cross member 2 whose overall direction is parallel to the side members.
• This insertion is provided, in the structural cross member 2, in a groove 20 with a semi-cylindrical bottom, for the first spar 10, and in a cylindrical bore 21 (drawn in dotted lines in the figure) for the second spar, the grooves and bores being formed in transverse arms 2a of the cross member 2.
• the plate 23 which is used for the final mounting by pivoting of the part 1 a of the module 1.
• FIG. 2 illustrates a first stage of assembly in which the module 1 is assembled by rotational connection on the cross member 2.
• the longitudinal members 10 are inserted in the cylindrical receiving supports, such as the groove 20 formed in the support arm 2a of the cross member 2.
• the groove is deep enough to prevent the side member from detaching during the pivoting of the part 1a produced by the operator once the first assembly has been carried out.
• the illustrated front view shows an example of removable hooking means of the module on the cross-member, capable of carrying out the second mounting step according to the invention.
• additional means are of the clipping type.
• these means consist of a male hook-shaped part 12 fixed to part 1 a of module 1 and of a female part formed by an orifice 22 cut from a plate 23 integral with the cross-member 2.
• the hook 12 has a portion with an elastic double blade
• the head 12b of the hook 12 terminated by a head 12b.
• the dimensions of the orifice 22 are adjusted to allow a forceful insertion of the hook thanks to the elasticity of its blades.
• the stiffness characteristics of the material of the blades are however chosen, as well as the shape of the heads adapted, to achieve a firm clipping. After insertion, the head 12b of the hook 12 rests on the plate 23.
• FIG. 4 shows the assembly of the cross member 2 and of the module 1 after connection between the hooking means of the part 1a of the module.
• the distance between the hooking means and the rotational connection means is determined so that the longitudinal members 0 are held tight in the groove 20 by locking the hook 12 in the plate 23.
• To dismantle the module it suffices to undo the removable hooking by bringing the blades closer to the hooks, the hook heads then passing through the orifice.
• the invention is not limited to the embodiments described and illustrated. It is for example possible to provide several clipping means, to reverse the male and female clipping or connection means in rotation on the cross member and the air conditioning module.
• the invention can be applied to any type of vehicle having a dashboard: private plane, outboard canoe, etc.
