Description

Seat cushion module Technical Field The present invention relates to a seat cushion module. Background In the manufacture of motor vehicle seats, mats made of PU foam or similar materials are generally used. The cushion material is proportioned to the largest volume in terms of volume of the vehicle seat. However, such mat materials are generally not sustainable due to their poor recyclability. Furthermore, the final assembly is relatively complex, since in modern vehicle seats further seat components must be mounted under, in or on the cushion material in addition to the cushion material. Because such assembly is typically done in high wage countries near the vehicle manufacturer, each individual assembly step results in relatively high costs. Disclosure of Invention The object of the present invention is therefore to simplify the production of a vehicle seat in this respect and in particular also to take account of sustainability factors. This object is achieved by a seat cushion module having the features of claim 1. Advantageous embodiments are given by the dependent claims. According to the invention, a seat cushion module is provided for installation on a motor vehicle seat. The modular design has the advantage that the seat cushion and possibly further components fastened thereto can be assembled on time in only one operation without great assembly effort. According to the invention, the seat cushion module has a front side and a back side and comprises a compressible, breathable cushion material. Compressible means here primarily that the volume of the pad material can be compressed preferably elastically by the action of a force. The pad material is surrounded by a cover. By enclosing it is meant that the mat material does not have to be forced completely enclosed by the casing. Rather, a complete enclosure is conceivable, but it is likewise conceivable for the housing to enclose only a portion of the mat material. That is, the housing can have a recess not only on the front side but also on the rear side. The housing is formed according to the invention at least on the front side of the seat cushion module from a nonwoven and/or at least partially airtight material and on the rear side of the seat cushion module I) Constituted by non-woven and/or at least partly airtight material, and/or Ii) by means of a carrier. Preferably, the housing has at least one air outlet opening, preferably a plurality of air outlet openings, on the front side, and at least one air inlet opening on the rear side. The seat cushion module according to the invention, which is suitable for both the backrest and the cushion of the seat part, is designed as a modular component by means of a cushion material which is embodied as a cover, which can be simply assembled in the target position. Furthermore, the seat cushion module according to the invention provides the possibility of enabling air penetration through the seat cushion module and the possibility of mounting further components on the seat cushion module, for example on the housing. For this purpose, the housing is a nonwoven material, and the housing can also be made of a plurality of materials, for example, the rear side can be formed as a carrier from a material (for example, plastic) that is harder or stiffer than the front side of the housing. The carrier may alternatively or additionally be a module carrier or a preferably elastic suspension element, for example in the form of a pad. The housing does not have to completely surround the pad material. It is conceivable that the housing is composed entirely of nonwoven material, or that one part is composed of nonwoven material and the other part, preferably on the rear side, is composed of a carrier, preferably a module carrier, a plastic carrier, a foam layer, a felt layer, or another preferably elastic suspension element, or comprises a corresponding structure. Alternatively or additionally, the entire seat cushion module can be fastened to a module carrier, a plastic carrier or an elastic suspension element. As nonwoven and/or at least partially airtight material, for example, felt material or in principle another at least airtight or at least partially gas-barrier material may be used. For example, the nonwoven and/or at least partially airtight material may have a membrane, coating or film of a material that is impermeable to air or inhibits air flow. Woven materials having at least partially gas impermeable layers or coatings or impregnations are also contemplated. Airtight or airtight in this context means that there is absolute breathability, but this is not mandatory and is sufficient as long as breathability is sufficiently strongly damped. If an air inlet opening or an air outlet opening is present in the housing, through which a major proportion of the air can flow in or out, a sufficiently strong damping is present. Preferably, such a proportion is important in the case that more than 90% of the air l
