The central base member comprising two guide elements (4,5) arranged on opposite lateral side portions of the central base member (2), relative to each other. The headrest further comprising two lateral support members (6,7), which are connected to and guided by the guide elements, wherein the lateral support members are displaceable relative to the central base member. The headrest further comprising a cushioning element (9) covering a head supporting side (8) of the central base member and the pair of lateral support members, and having a thickness T from the head supporting side, and comprising a cover (11) upholstered over the at least one cushioning element and at least parts of the central base member and the pair of lateral support members. Each guide element is curved so that each lateral support member is rotatable around an axis A, B arranged in front of and within a distance between T/2 and 3T/2 from the head supporting side of the central base member and the pair of lateral support members. The headrest reduces or eliminates unintentional drift of lateral support adjustment and reduces or eliminates chafing to the headrest cover.

The invention relates to an evaporator (130; 230; 330; 430; 530) comprising a first core (331; 401; 501); and a second core (332; 402; 502), the first core (331; 401; 501) being arranged downstream of and overlapping the second core (332; 402; 502) in an air flow direction through the evaporator. Each core comprises an upper tank (503; 505) at a first end of the evaporator and a lower tank (504; 506) at a second end of the evaporator. Multiple conduits are arranged to allow fluid communication between the upper and lower tanks. Refrigerant supplied through the refrigerant inlet (410; 510) is directed from the first upper tank (503) to the first lower tank (504) a first path (P1). A split second path (P2, P2') is directed from the first lower tank (504) to the first upper tank (503) on either side of the first path (P1). Refrigerant is then directed from the second upper tank (505) to the second lower tank (506) in a split third path (P3, P3') on either side of a fourth path (P4). The fourth path (P4) is directed from the second lower tank (506) to an outlet (420; 520) at the second upper tank (505).

The present disclosure relates to a corner element (38, 40) for attachment of a cargo protection device (14) to an interior (10) of a vehicle (12). The corner element comprises a holding portion (42), adapted to be located at least partly in or at an upper corner (24, 26) of the cargo protection device, and an attachment portion (44) for attachment of the corner element to the interior of the vehicle. The holding portion comprises a first leg (46) and a second leg (48) connected by a central portion (50), the first leg extending from the central portion in a first direction (D 1 ) and the second leg extending from the central portion (50) in a second direction (D 2 ), such that the first and second directions in an untensioned state of the holding portion form an angle ± with each other with 90° < ± < 110°. The attachment portion extends from the central portion in a third direction (D 3 ), which has a first component in a direction opposite to the first direction and a second component in a direction opposite to the second direction. The disclosure further relates to a cargo protection device, comprising a foldable and/or rollable fabric portion (20) and at least one such corner element, and a method of attaching such a cargo protection device to the interior of the vehicle.

The present invention relates to a twin scroll turbocharger device for an internal combustion engine having at least one combustion chamber. The twin scroll turbocharger device comprises a turbine portion comprising a turbine wheel; a first turbine scroll and a second turbine scroll; and a first turbine scroll valve for allowing control of a flow of the exhaust gas through the first turbine scroll; a compressor portion comprising a compressor inlet; a compressor outlet; and a compressor wheel for pressurizing air received from the compressor inlet and providing pressurized air to the at least one combustion chamber via the compressor outlet. The twin scroll turbocharger device further comprises a container for storing pressurized gas; a container conduit fluid flow connecting the container and the turbine portion for controllably providing pressurized air from the container to a first container inlet located between the first turbine scroll valve and the turbine wheel.

The present invention relates to an air supply arrangement (3) for a vehicle (1). The air supply arrangement (3) comprising - a housing (15) comprising an air inlet (19) adapted to receive an air stream from outside of the vehicle (1) and an outlet (21) adapted to convey the air stream to a vehicle climate control system, and - a cowl (17, 17') provided within the housing (15), wherein the cowl (17, 17') is arranged such that the air stream is split into at least two air stream portions, whereof a first air stream portion (25) passes between the cowl (17, 17') and a top portion (55) of the housing (15), and a second air stream portion (27) passes below the cowl (17, 17'). The invention also relates to a vehicle (1) comprising such an air supply arrangement (3).
