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 an An acoustic protection system for a motor vehicle has two walls extending opposite each other; an elastically compressible acoustic decoupling layer arranged in compression at least along its periphery between the walls, the layer having two opposing faces pressed respectively against each of the walls, the faces being connected to each other by an edge, the layer being enclosed in a bag made from plastic film closed so as to form a sealed barrier on the edge, at least one air passage hole being provided in the bag opposite at least one of the faces, the hole being arranged at a distance from the edge so as to provide, around the hole, a seal created by the bag bearing on the corresponding wall.

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: A method for producing an automotive equipment part includes the following steps: arranging a porous layer in a foaming mold; injection, on one side of the porous layer, of a foam precursor; expansion of the precursor material to form a foam base layer bonded to the porous layer; and extraction from the mold of the equipment part including the porous layer and the foam base layer bonded to the porous layer. The method further includes a step for injecting a pressurized fluid on a second side of the porous layer to form a counter-pressure to the expansion of the precursor material.

Abstract: An object holder assembly in a vehicle that includes a floor having a metal layer and an upper face intended to support at least one object. The vehicle includes at least one trunk separator having a base able to be applied on the floor and a separating partition. The separator includes a fastening device having an active configuration in which the fastening device is able to fasten the base on the floor when a lower face of the base is in contact with the upper face of the floor and a released configuration of the separator. The separator has a control member for the fastening device, able to be actuated between a locking position, in which the control member activates the fastening device, and an unlocking position. The fastening device has a movable magnet able to cooperate with the floor in the active configuration.
