Abstract: An assembly for a vehicle seat that includes: a support element defining a through opening, a padding element attached at least in part to the support element, and a ventilation system assembled to the support element in fluidic communication with the through opening. An inner surface of the support element and/or an inner surface of the padding element define at least one groove. An inner surface of the groove, the inner surface of the support element, and an inner surface of the padding element define an internal volume there between in fluidic communication with the through opening.

Abstract: A vehicle seat element lining comprises a cushioning comprising at least one first face intended to be oriented towards an occupant of the vehicle seat and a second face, opposite the first face, the cushioning having at least one hole opening on the first and/or the second face of the cushioning; at least one vibrating device disposed in a hole, each vibrating device comprising at least two first snap-fit reliefs; a plurality of distinct vibrating device brackets, each comprising a base, overmolded by the cushioning, and a second snap-fit relief, each vibrating device being fastened to at least two respective brackets, by snap-fitting the first and second snap-fit reliefs.

Abstract: A backrest of a vehicle seat comprises a backrest frame, a support plate fixed to the backrest frame, and at least one vibrating device. Each vibrating device is fixed to the support plate by means of at least one damping element. Preferably, each vibrating device is fixed on a face of the support plate opposite to the face intended to be oriented towards an occupant of the seat, at least a portion of each vibrating device being received in a respective through-hole in the support plate.
