Description

The invention relates to a seat part with the features of the preamble of claim 1 or 2 and a vehicle seat, in particular a motor vehicle seat with the features of the preamble of claim 25. Prior art Vehicle seats known from the prior art have a seat part and /or a backrest. DE 102007017001 A1 discloses a seat cushion shell for a seat part of a vehicle seat, which includes a cushion shell section that has a cushion receiving surface and a side protection section that is in one piece with the cushion shell section, the cushion shell section and the integrated side protection section being made of plastic. DE 202011105603 U1 discloses a backrest structure for a backrest of a vehicle seat, with two backrest side rails, an upper crossbar and a lower crossbar, which connect the two backrest side rails with one another, with at least one of the backrest side rails having a profile cross-section in the form of a C-profile, at least in sections a web, a first flange, a second flange, a first edge flange and a second edge flange. OBJECT The invention is based on the object of improving a seat part of the type mentioned at the outset and a vehicle seat of the type mentioned at the outset, in particular a seat part or to provide a vehicle seat for an optimized assembly of components or assemblies on the seat part or on the vehicle seat. Solution This object is achieved according to the invention by a seat part having the features of claim 1 or 2 and by a vehicle seat, in particular a motor vehicle seat, having the features of claim 25. Advantageous configurations which can be used individually or in combination with one another are the subject matter of the dependent claims . A seat part according to the invention for a vehicle seat, in particular a motor vehicle seat, has at least one seat cushion shell, which is designed as a module carrier or component carrier for carrying different modules and/or components, in particular different functional modules and/or structural modules, and has a large number of integrated fastening areas, which are each designed universally for the positive and/or non-positive connection of the seat cushion shell with the various modules and/or components (also called equipment components). Another seat part according to the invention for a vehicle seat, in particular a motor vehicle seat, has at least one seat cushion shell designed as a module carrier or component carrier, the module carrier having an integrated interface designed to carry a module designed as a spring mat section. The advantages achieved with the invention are, in particular, that the integration of fastening areas for carrying various modules and/or components and/or the integration of an interface for carrying a kinematics of a module designed as a seat cushion depth adjuster provides a seat part for a vehicle seat which manufactured in an optimized manner, in particular assembled in a particularly cost-efficient and time-efficient manner, in particular pre-assembled can be and has few components. In particular, various modules and/or components, in particular functional modules and/or structural modules, can be mounted directly on the seat part without additional separate fastening means. Such a seat part pre-assembled with modules and/or components can be easily attached to a metal structure as a pre-assembled unit. Thus, an assembly on a main assembly line is simplified and corresponding stations can be omitted due to fewer parts. A so-called just-in-time process is thus significantly relieved and has improved cycle times due to fewer parts and direct assembly on the integrated fastening areas of the seat part. Due to the reduction in parts, tool costs, transport costs and assembly costs are also reduced. The seat part is designed to be more compact and lighter. In addition, testing effort and quality control are optimized and less expensive. Furthermore, the reduction in components also improves the recyclability. In one possible embodiment, the seat cushion shell with the integrated fastening areas, in particular the module carrier, is formed from at least one base material by pressure forming and/or injection molding. For example, the seat cushion shell is made from a thermoplastic material, for example by an injection molding process or by a pressure forming process. In addition, the seat cushion shell, in particular the module carrier, can be reinforced by means of an insert and/or an element made of a fiber-reinforced plastic (organic sheet) or other means. The seat cushion shell, in particular the module carrier, can be formed as a one-component part or a two-component part made from at least two different materials, in particular at least two different plastic materials and/or from a plastic material and a metal material. For example, the integrated fastening areas are formed on an upper side, a lower side and/or in the area of longitudinal sides and/or transverse sides of the seat cushion shells. In particular, the fastening areas are introduced into the seat cushion shell, for example moulded, moulded, injected, embossed, pressed in, pressed in and/or reshaped. A further aspect of the invention provides that the seat cushion shell is designed as at least one further module, at least one seat part upholstery, a damping element, a spring element, a seat cushion depth adjuster, a side bolster adjuster, a side skirt, a lamp, a control panel, a switch, a to carry fans and/or a ventilation system. The integrated fastening areas are designed, for example, as integrated assembly sections for the various modules and/or components. The integrated attachment areas, in particular the integrated assembly sections, include, for example, a number of integrated coupling interfaces, integrated attachment interfaces, integrated holding interfaces and/or integrated module interfaces. At least one node element and/or one coupling element, such as a rotary joint, for example, is or is provided as an integrated coupling interface. Channels, grooves, molded beads, shaped pieces, profile indentations, embossing, molded and/or traversing bushings, through-openings and/or recesses or other similar means are provided as integrated holding interfaces, for example. For example, fastening channels, fastening hooks, latching elements, wedge elements, nut elements, threaded elements, clip elements, eyelets and/or fixing elements or other similar means are provided as integrated fastening interfaces.

The fan can have a round shape. The ventilator can have several eyelets, which are distributed evenly around the circumference of the ventilator. The fan can be clipped into the mounting opening by means of the eyelets and the projections. In this way, the fan can be fixed to the seat cushion shell without screws. A buffer can be arranged between the fan and the mounting opening of the seat cushion shell. The buffer can serve to reduce vibrations. The buffer may have a round shape. The buffer can have a number of eyelets which are distributed evenly around the circumference of the buffer. The buffer can be produced as one component together with the seat cushion shell by means of a two-component injection molding process or multi-component injection molding process. The buffer can be produced together with the fan as one component by means of a two-component injection molding process or multi-component injection molding process. The seat cushion shell can have distribution channels extending from the assembly opening. The distribution channels may be disposed in a surface of the seat cushion pan and integrally formed in the seat cushion pan. By means of the distribution ducts, the air that can be conveyed by the fan can be distributed behind a foam part of the seat part upholstery of the seat part or be directed to specific areas. The seat cushion shell preferably has at least one opening which serves to receive a cover fastening element. The cover fastening element can be fixed to the seat cushion shell by inserting it into the opening and then rotating it by 90° using the principle of a so-called bayonet lock. To secure the cover fastening element in the fixed position, the seat cushion shell can have two wedges in the region of the opening, which secure the cover fastening element on a side (underside) of the seat cushion shell opposite the cover fastening element. The trim cover fastener may include hooked portions protruding from a top surface of the seat cushion pan. Corresponding counter-elements connected to a cover of the seat cushion can be connected in the hook-shaped sections. The seat cushion shell can have integrally formed support sections which serve to form side bolsters or on which provided side bolsters of the seat part can be supported. In the area of the support sections of the seat cushion shell, side bolster adjusters can be provided for individual adjustment of the side bolsters of the seat part. For fastening the side bolster adjusters, the seat cushion shell can have two projections on a lateral edge as a third integrated assembly section. The side bolster adjuster can be fixed to the seat cushion shell by means of a holding element.

Mounting sections in the form of holding means can be provided on an underside of the seat cushion shell in order to fix various lines. The holding means can be a so-called omega clip, for example. Routing channels can be provided on the underside of the seat cushion shell in order to route various lines. The laying channels can be formed by means of ribs protruding from the seat cushion shell. The lines can be electrical lines of a cable harness. The lines can be pneumatic lines. The seat cushion shell can additionally have fixing elements, by means of which connecting means of sensor housings or valve housings that are designed to cooperate accordingly can be fastened. A reinforcement section can be used for local reinforcement of the seat cushion shell. The reinforcement section can have a rib structure formed in the seat cushion shell. The reinforcement section can be a reinforcement made of a fiber composite plastic, in particular a glass fiber reinforced plastic, applied locally to the underside or top of the seat cushion shell. The seat cushion shell can have an overmoulded carrier body, in particular made of metal, in the reinforcement section. Hollow reinforcement sections in the seat cushion shell can be produced by means of internal pressure injection molding. An alternative embodiment of a side skirt preferably has no control panel arranged on the side of the seat part. To reinforce the side skirt, a rib structure can be arranged between the side skirt and a seat kinematic mechanism that can be concealed by the side skirt or other devices for providing further seat functions. The side skirt may also have hook portions which engage in the seat cushion shell retaining apertures are fixable. A control panel for actuating seat functions can be arranged on an upper side of an outer edge portion of the seat cushion shell. The control panel can be a touch-sensitive control panel. A vehicle seat according to the invention comprises at least the seat part described above and/or a backrest. The backrest can be arranged statically or movably, in particular pivotably, on the seat part. Advantages of the vehicle seat described above can be that the vehicle seat according to the invention can be manufactured with a reduced number of components. At the same time, the weight of the vehicle seat can be reduced compared to a conventionally manufactured vehicle seat with an identical range of functions. Due to a reduced number of components to be assembled, the number of work steps and/or tools required to assemble the vehicle seat is also advantageously reduced, which further affects assembly time and quality control and thus also the manufacturing costs of the vehicle seat. In summary and to put it in other words, a component carrier for a seat surface and/or a backrest can be introduced as the seat cushion shell. The component carrier can be made of a thermoplastic material, for example by an injection molding process. The component support can be a structural support element of the seat. The component carrier can be reinforced in sections by means of an insert, an element made of a fiber-reinforced plastic (organic sheet) or other means. The component carrier can be a one-component component or a two-component component. In the case of a two-component part, an additional soft component can be provided in order to enable a higher degree of functional integration. For example, vibrations can be better decoupled and/or the flexibility of individual areas can be adjusted more individually.
