Abstract: The device serves to suspend heating elements in the interior of a receptacle drum of a drier. The drier is provided with a rotary drive for the drum, and the heating elements exhibit a tubular conformation. The heating elements are guided in a support comprising a basic element and a clamping element positionable relative to the basic element. Both the basic element and the clamping element are provided with guidance recesses for the heating elements. The heating elements extend through the guidance recesses. The clamping element is arranged adjustable in a radial direction with respect to the longitudinal axis of the drum.

Abstract: A motor vehicle includes a motor vehicle body having side frames which support a roof area, the roof area including at least two roof panels which lie flat and parallel in the closed position and can be moved to an open position. The roof panels are constructed so that they can be moved by a guiding mechanism from the flat, parallel closed position into a packed open position completely in the interior of the vehicle body at a distance from the roof region and disposed essentially vertically and parallel to one another.
