A device (10) for regulating cooling air on a motor vehicle has a roller blind (12) that can be moved across an air inlet opening of the motor vehicle. The device (10) has a horizontally aligned sealing frame (18) for guiding the roller blind (12) across the air inlet opening. The device (10) comprises a supporting frame arranged within the sealing frame (18) for supporting the roller blind (12) against the cooling air.

An extension of a grille extends rearward and in a left-right direction of a vehicle. The extension is located rearward from a grille body and below a ventilation hole. An extension rear edge is arranged above a structure front upper edge. An extension front edge at which the grille body and the extension are connected to each other is arranged below the structure front upper edge. The extension is inclined from the extension front edge toward the extension rear edge. The extension includes weak portions that divide the extension into a plurality of sections in the left-right direction.

An exemplary vehicular duct system includes, among other things, a duct wall of a first material composition, and a skeleton of a different, second material composition that is at least partially embedded within the duct wall. The skeleton is more compliant to an amount of force applied in a first direction than to the amount of force applied in a second direction that is perpendicular to the first direction. An exemplary duct support method includes, among other things, supporting a duct wall having a first material composition with a skeleton having a different, second material composition. At least a portion of the skeleton is embedded within the duct wall. The skeleton is more compliant to an amount of force applied in a first direction than a second direction perpendicular to the first direction.

An air inlet device for a coding device of an electric vehicle, having an air inlet duct with a duct wall delimiting a duct volume and at least one duct opening for the admission of ambient air for guiding to the cooling device. An acoustic, device for pedestrian protection is arranged in the duct wall in a flow-neutral manner with respect to the flow of ambient air, with a speaker device for generating a protective noise.

A flow straightener of a vehicle provided with a bumper and a cab disposed above the bumper includes a first opening section provided in the bumper and/or the cab and opened toward a front of the vehicle, and a second opening section connected to the first opening section via a connecting path and opened toward an outer side in a vehicle width direction from a location further on an inner side in the vehicle width direction than front wheels of the vehicle such that traveling wind led into the first opening section passes through a front wheel forward region defined as being behind the first opening section in a lower region of the cab and in front of the front wheels.

A heat exchanger including a first tank having a first inlet through which coolant flows into the first tank. A core has a plurality of coolant conduits that receive coolant from the first tank. A second tank receives coolant from the plurality of coolant conduits. The second tank has a first outlet through which coolant flows out from within the second tank. A flow guide is within the first tank or the second tank, and is movable to vary how much coolant flows through different ones of the plurality of coolant conduits.

An automotive vehicle includes a body with a front portion, an underbody portion, a wheelhouse disposed in the underbody portion, and a front fascia disposed at the front portion. The wheelhouse is provided with a liner. A movable member is disposed between the wheelhouse liner and the front fascia. The movable member has a venting position and a barrier position. In the barrier position the front fascia, movable member, and wheelhouse liner define a generally contiguous surface, and in the venting position the movable member is displaced at least partly away from the body relative to the barrier position. An actuator is coupled to the movable member and configured to actuate the movable member between the venting position and the barrier position. A controller is configured to control the actuator to move the movable member to the barrier position in response to a first operating condition being satisfied.

A vehicle includes a grille assembly, a radiator, and a bumper reinforcement beam. In addition, the vehicle includes an air deflector assembly that further includes an air deflector body portion that extends away from the radiator in the vehicle longitudinal direction over the bumper reinforcement beam and toward the grille assembly. The air deflector body portion includes an upper wall portion and an intermediate wall portion. The intermediate wall portion intersects the upper wall portion at an angle. The air deflector body portion includes a lower wall portion that is offset from the upper wall portion in the vehicle lateral direction by the upper wall portion. The intermediate wall portion intersects the lower wall portion at an angle so to facilitate collapsing of the air deflector body portion upon a vertical impact by a leg impactor during a pedestrian leg impact test.

A grill shutter device for vehicle includes a grill, a shutter, and a drive source. The grill is provided with an opening penetrating the grill in the front/rear direction. The shutter includes fins opening and closing the opening, lining up in a vehicular width direction, and curving so as to fit into a curved configuration of the grill. The drive source drives the shutter so that the fins open and close the opening. The fins include a body plate, and a support shaft fixed to the body plate, extending in a direction linearly linking between vehicular-width-direction opposite ends of a corresponding site in the opening, and supported to the grill so as to rotate when actuated by the drive source. Moreover, a universal joint joins between the support shafts of two of the fins neighboring one another in the vehicular width direction.
