A device holder assembly for use in a vehicle includes a compartment having a top side opening, a device holder attached to the compartment for holding a mobile electronics device, and a closure attached to the compartment. The gas generator carrier has first projections and the covering cap has second projections each associated to one of the first projections. The clamping slot is configured to hold or clamp within the clamping slot a bottom portion of a valence so that the bottom portion tracks the first shape. Further, the single sheet handling device has a separating device with separating elements for the sheet-by-sheet removal of single sheets of the stack from the container.
