Abstract: The present disclosure relates to a backrest for a vehicle seat comprising a backrest frame and a upper backrest adjustment device comprising a support member intended to receive, bearing against a front face, the upper back of an occupant of the seat, pivotably mounted on the backrest frame; at least one first connecting rod pivotably articulated relative to the backrest frame; an intermediate part between the support member and the first connecting rod, pivotably articulated relative to the support member and relative to the first connecting rod, an actuator for adjusting the position of the support member between a retracted position and an advanced position, the actuator comprising a pivotably articulated connecting part relative to the intermediate part.

Abstract: A process for the preparation of freeze dried liposome encapsulated amphiphilic drug compositions, which process comprises preparing a liposomal suspension of multilamellar vesicles (MLVs) which encapsulate an amphiphilic drug compsition, adding sorbitol to the liposomal suspension and lyophilisation of the suspension.

Abstract: A process for the entrapment of amphiphilic compounds as uncharged or ionic with different mole ratios of phospholipid to the amphiphilic compound. Preparations of ionic species of amphiphilic compounds in the absence of crystals can be prepared, while preparations of uncharged amphiphilic compounds can be prepared with the compound exclusively entrapped inside the liposomes, or partly entrapped inside the liposomes with extraliposomal crystals.
