Description

[0001] The invention relates to a lying device for a commercial vehicle cabin, a commercial vehicle cabin with such a lying device and a commercial vehicle with such a commercial vehicle cabin.

[0002] Commercial vehicles typically have a sleeping platform in their cab where a person can lie down, for example, to rest or sleep. Such a sleeping platform usually consists of a mattress and a mattress support, in particular a slatted frame with a wooden frame and aluminum cladding. To ensure a high level of comfort, the slatted frame often has additional springs. A relatively thick cold foam mattress made of a thermosetting plastic is often used as the mattress. The sleeping platform thus has a relatively high mass. Since commercial vehicles are used by different people, a topper is usually placed on the cold foam mattress, assigned to a specific person and removed from the cab after use.Over time, cold foam mattresses can absorb moisture, which can lead to pest infestations, particularly mite infestations. These infestations can trigger or exacerbate allergies, causing discomfort for those using the commercial vehicle. Such a sleeping platform can be made of various materials, such as plywood, synthetic fibers, aluminum, polyurethane foam, steel, and paint. If such a sleeping platform becomes worn or damaged, it must be disassembled, a complex process. Recycling such a platform is also complex and time-consuming. Due to the diverse materials used, the economical use of recycled materials is currently not feasible.

[0003] German patent DE 10 2015 004 217 A1 discloses a sleeping device arranged in the driver's cab of a commercial vehicle. Its sleeping surface for one person consists of a mattress resting on a mattress base with an integrated climate control system for active climate control of the sleeping surface. The mattress base comprises a mattress frame with a slatted base, beneath which three fans are arranged. The fans are connected to the vehicle's air conditioning system via a line.

[0004] Furthermore, DE 10 2006 044 410 B4 also shows a sleeping device in the cabin of a commercial vehicle. The sleeping device is foldable, and its lying surface, when unfolded, can be placed with one edge on the dashboard.

[0005] Finally, DE 102 37 783 A1 describes a foldable commercial vehicle bed with a removable mattress, wherein the bed is held in the unfolded state by means of two straps attached to the free longitudinal side of the bed, which are attached with their other ends to the cabin roof of the commercial vehicle and thereby hold the bed in a horizontal position.

[0006] The invention is therefore based on the objective of creating a lying device for a commercial vehicle cabin, a commercial vehicle cabin with such a lying device and a commercial vehicle with such a commercial vehicle cabin, wherein the aforementioned disadvantages are reduced, preferably do not occur.
