Abstract

The application relates to a radiator grill for motor vehicles which comprises a plurality of lamellae oriented parallel and arranged at mutual intervals, the free interstices between the lamellae being able to be closed by pressurizable flexible hose(s) as a function of the cooling water temperature of an internal combustion engine, with each of the pressurized adjacent hose(s) being braced mutually in the closed position. The invention provides that such a radiator grill can be developed so that no particularly high pressure needs to be exerted to deform the hose(s), since the hose(s) flex into a closing position and no particularly high strength requirements need be imposed for the resilient properties of the hose material as the hose(s) flex outwardly and do not inflate. Additionally, a simple clip mechanism is provided to attach the hose(s) to the lamellae.
