Abstract: A front lid for a vehicle, especially a motor vehicle, which front lid includes an outer panel, where, in a predetermined region or in the entire area of the front lid below the outer panel, at least one inertia mass is arranged, and the inertia mass is formed of a flexible heavy layer.

Abstract: Method of controlling the conveying speed of a grate cooler as a function of the state of the bed of material to be cooled in the initial region of the cooler while taking into account the flow resistance of said bed of material. According to the invention, the conveying speed, in addition to being controlled as a function of the flow resistance, is also controlled as a function of the height of the bed of material to be cooled.

Abstract: A passenger-restraining system, in particular for children and wheelchair occupants in motor vehicles. The restraining system includes at least one safety-belt arrangement with a lap belt and an associated cushion element. The cushion element has a body made of at least one cushion material which can be deformed, absorbing energy in the process, and has a guide slit for the lap belt. The element also has an insert which is embedded in the deformable cushion material and surrounds the guide slit. In order to convert a large amount of kinetic energy into deformation work in the cushion element, and thus to dissipate said kinetic energy, without there being any risk of injury to the individual secured by the restraining system, the insert includes, a plurality of layers of a thin, flexible foil, sheet material and/or fabric which are separated from one another by a layer of the cushion material.
