Abstract: A vehicle seat arrangement in a vehicle is disclosed. The vehicle seat arrangement comprises a vehicle seat with a back portion and a seat portion, said seat portion comprises a front section, adapted to support legs and knees of a user, and a rear section adapted to support the user's weight. The rear section of the vehicle seat comprises a deformation unit adapted to reduce the force exerted on the user during a crash, the force being absorbed through plastic deformation of a deformation portion. The deformation portion is adapted to deform with a linear deformation property of the energy absorption, after a force threshold is exceeded. A vehicle comprising such a vehicle seat arrangement, and a method used in said vehicle seat arrangement are also disclosed.

Abstract: The present invention relates to a vehicle seat system for reduction of vertical peak acceleration of a person seated in a vehicle seat during impact. The vehicle seat system comprises a seating structure and a trim at least partially enclosing the seating structure. The trim is releasably fastened to the seating structure by means of interconnected trim fastening means comprising at least two parts adapted to release from each other when the vertical peak acceleration exceeds a predetermined limit value, subsequently reducing the vertical peak acceleration. The present invention further relates to a vehicle comprising the vehicle seat system.

Abstract: A purge ejector assembly for an engine has a first fluid passage with a nozzle device therein that raises flow velocity of air and a first valve therein between an engine manifold port and the nozzle and permitting flow from the engine manifold port toward the nozzle device while restricting reverse flow. A second fluid passage has a second valve therein between the engine manifold port and a purge flow port, and permitting flow from the purge flow port toward the engine manifold port while restricting reverse flow. A third fluid passage extends from a second passage position located between the purge flow port and the second valve to a first passage position located between the nozzle device and an air inlet channel port. A third valve in the third passage permits flow from the purge flow port toward the air inlet channel port, while restricting reverse flow.
