Abstract: An assembly for a first backrest and a second backrest, the assembly comprising a first suspension system for attachment to a first frame and a second suspension system for attachment to a second frame, wherein: the first suspension system comprises a first main support, a first ancillary support and a first structural core to which the first main support and the first ancillary support are attached, the second suspension system comprises a second main support, a second ancillary support and a second structural core to which the second main support and the second ancillary support are attached, the second main support is geometrically identical to the first main support, and the second ancillary support geometrically differs from the first ancillary support.

Abstract: The present disclosure relates to a modular squab cushion, configured to be attached to a squab structure having a squab structure, the squab structure being configured to removably attach the modular squab cushion, the modular squab cushion comprises, in the assembled state: a main (or central) base having a lower surface configured to be attached to the squab structure, a central padding resting on an upper surface of the main base and forming a central portion, a central trim covering that covers the central padding, at least one modular lateral bolster removably attached to the main base.

Abstract: The present disclosure relates to a modular seat bottom cushion, configured to be attached to a seat structure having a seat bottom structure comprising two lateral flanges spaced apart by a front transverse tube and a rear transverse tube, the modular seat bottom cushion comprising, in the assembled state: a base comprising a mechanical interface system for attachment to the seat bottom structure, padding resting on an upper surface of the base a covering which covers the padding.

Abstract: A suspension system for a backrest of a vehicle seat, wherein the suspension system comprises: a main support, the main support has a main plate, an ancillary support, the ancillary support has an ancillary plate, the ancillary plate has a central portion extending along the extension of the main plate in an elevation direction, and a structural core extending in the elevation direction between an upper structural end and a lower structural end, the upper structural end and the lower structural end are intended to be attached to a frame, the main support and the ancillary support are attached to the structural core.

Abstract: A ventilated system for a vehicle seat. The ventilated system includes a ventilator fan, a fan housing and a fixing member. The fan housing covers the ventilator fan, and the fixing member is adapted to be secured in or on a trim part of the vehicle seat. The fan housing or the fixing member includes a concentric ring element having a wall portion and an engaging element. The fixing member or the fan housing has an engaging portion adapted to engage with the engaging element of the concentric ring element. While engaging, the wall portion of the concentric ring element forms a wall around the airflow to avoid any air leakage from/in-between the engaging portion of the fixing member and fan housing.
