Abstract: System for rotatably mounting a covering panel (2) for a motor vehicle luggage compartment on a trim (3), said system comprising two devices (4) for rotatably slotting said panel, each of said devices comprising: a finger (5) and a receiver (6) for slotting said finger, said finger having a recess (7) provided with a first opening (8), the system further comprising a cavity (9), said receiver being mounted in said cavity, said first opening leading into a second opening (10) provided in said cavity and having an upper wall (11), a bottom wall (12) and a middle wall (13), a decoupling means (14) made of elastically compressible material extending between said receiver and said upper and lower walls, an air gap (15) being provided between said receiver and said middle wall.

Abstract: The invention relates to a headrest (1) for a motor vehicle seat, said headrest comprising a rigid structure for mounting said headrest at the top of the backrest of said seat, said structure being provided with at least one sound transmission plate (6), said plate being provided with an electrodynamic transducer (7) and being connected to said structure via an acoustic decoupling means (8) made of elastically deformable material, so as to prevent transmission of vibrations from said plate to said structure.

Abstract: The invention relates to a system for mounting a transducer on an interior trim panel of a motor vehicle. The system includes a base with a thread, and a peripheral receiving track and an interface attached to the transducer having a part for attaching to base. The interface has a reciprocal thread and a flexible collar forming a reciprocal track. The receiving track has a substantially flattened frusto-conical shape. Before screwing the receiving and reciprocal tracks together, the tracks are placed in contact along a circular peripheral line and, once the screwing has been carried out, the reciprocal track deforms in order to bear by its surface on the receiving track.

Abstract: A motor vehicle inner trim panel having a molded core and: a base which is overmolded by the core in an attachment zone, the base being provided with forked ties which project from the core; a ring which is provided with receiving means interlocking with the forked ties, the ring further being provided with two electric connectors, the central opening of the ring being provided with a thread; a transducer which is provided with a generally cylindrical attachment portion (12) which is threaded and screwed into the opening, the free end of the attachment portion abutting in the zone so as to ensure gripping contact between the forked ties and the receiving means, the transducer further being provided with two reciprocal electric connectors on which each of the connectors abut, respectively.

Abstract: The invention relates to a system (1) for rotatably mounting and electrically connecting a covering panel (2) for a motor vehicle boot to a side interior trim (3) of the boot, the system comprising a front zone (4) of the interior trim provided with a pin (5) and a front corner (6) of the panel provided with a means (7) for receiving the pin by interlocking, the means being provided with at least one pair of electrical connectors (10) and the pin being provided with at least one pair of reciprocal connectors (12) which define two non-contiguous strips which follow on from each other and, when viewed in longitudinal vertical cross-section, fall within two opposite angular sectors of the same circle, so as to ensure a connection between the connectors and reciprocal connectors in all the positions occupied by the panel between its covering and access positions.

Abstract: The invention relates to a panel with a porous shell and a spring layer, part of which enters the shell and produces an integrated sealed barrier. The foam of the shell is an integral skinned foam and the shell has a core with a substantially homogenous density and a porous skin. The overall density of the shell is between 150 and 350 kg/m3. The skin thickness is between 0.3 and 2 mm and has a permeability such that a 2 mm thick foam strip cut into the shell and integrating the skin exhibits air flow resistance of between 250 and 2000 N.s.m?3.

Abstract: The invention is a trim panel having a moulded structural core. The core has two edges connected to each other along a joint, the joint is convex and radiated. The edges are connected to each other gradually, and the core has a back face and a front face.
