Abstract

For the purpose of a visually appealing design of a folding table (20) for a motor vehicle (1) having a carriage (30) and a with a decorative cover (25) provided on the carriage (30) slidably mounted carrier plate (35) is provided in that the carriage (30) and / or the carrier plate (35) and / or the decorative cover (25) are or are formed from a carbon fiber-reinforced plastic.

Description

The present invention relates to a folding table for a motor vehicle according to claim 1, a vehicle seat equipped therewith according to claim 7 and a vehicle equipped with such a folding table according to claim 8.

From practice folding tables for motor vehicles are known which can be fastened by means of a frame to a motor vehicle seat or another component of a vehicle interior. In this case, a carriage is attached to the frame, on which a support plate is slidably mounted in each case. On the support plate itself, a decorative cover is arranged, which serves as a storage area for a user of the folding table. These known folding tables sometimes seem bulky, which is not always desired.

It is an object of the present invention to overcome this disadvantage.

This object is achieved by a folding table for a motor vehicle, which has a carriage and provided with a decorative cover, slidably mounted on the carriage carrier plate, characterized in that the carriage and / or the carrier plate and / or the decorative cover is formed of a carbon fiber reinforced plastic or are. The solution according to the invention is characterized on the one hand by the fact that the folding table is easy due to its geometric and material design. In addition, due to the carbon fiber material, it also looks optically light and is perceived as such by a viewer.

In principle, the carbon fiber composite material provided according to the invention may be any suitable form of carbon fiber composite material. Thus, the carbon fibers provided therein as high-strength (HT), as so-called intermediate (IM), highly rigid (HM), with high modulus (UM), ultra high modulus (UHM), as so-called Ultra Modulus Strength (UMS) or be designed as high-strength / high-strength (HMS) fibers, which are present as short fibers, long fibers or continuous fibers. According to the invention, the carbon fibers can be arranged in particular in the form of woven fabrics and / or braids and / or layers (in particular multi-axial layers).

According to a preferred embodiment, the carriage and / or the carrier plate and / or the decorative cover are formed from a carbon fiber reinforced plastic containing molding compound. The molding compound may advantageously be formed from a bulk molding compound (BMC) or sheet molding compound (SMC), since this can already be integrated during the manufacture of a folding table according to the invention any kinematics and connection elements for its adjustment or support.

Preferably, the inventively provided carbon fiber composite material consists at least partially of recycled carbon fibers.

According to a preferred embodiment, the carbon fibers are formed from a precursor fiber based on a renewable raw material, preferably lignin, since this further improves the sustainability of the motor vehicle according to the invention. It should be noted that the precursor fiber may advantageously comprise polyacrylonitrile and at least one polymer selected from the group consisting of lignin, lignin derivatives, glucans, cellulose and any mixtures of two or more of the aforementioned compounds.

Also, a suitable matrix material can be chosen freely and in particular consist of a thermosetting material, for example an epoxy resin, a polyester, a vinyl ester or bismaleimide (BMI). Alternatively it can be provided to form the matrix of an elastomer, preferably polyurethane (PUR).

The carbon fibers may be embedded in a matrix, which is formed in particular from a thermosetting material. In a particularly preferred manner, however, the carbon fibers are embedded in a thermoplastic matrix, so that the advantages described above are supplemented by facilitated recyclability of the motor vehicle according to the invention. The thermoplastic matrix may in particular consist of a polypropylene (PP), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyamide (PA), in particular a PA 6 or PA 6.6, polyethersulfone (PES), polybisphenylsulfone (PSF), polyethyleneimine (PEI), Polyphenylene sulfide (PPS) or polyetheretherketone (PEEK) exist.

In order to further improve the optical lightness of the folding table according to the invention in an advantageous manner, the carbon fiber reinforced plastic decorative cover is formed as a fabric with a plain weave, body weave or satin weave.

The optical lightness of the folding table according to the invention is additionally improved in an advantageous manner when the decorative cover contains glass fibers and / or aramid fibers and / or colored plastic fibers.

The aforementioned object is also achieved by a motor vehicle seat having a folding table of the type previously disclosed. The advantages mentioned above apply adequately.

In addition, it is advantageously possible to attach the folding table according to the invention also on any other components in a motor vehicle, particularly preferably a center tunnel, a vehicle floor, a vehicle pillar, in particular a B-pillar, a vehicle roof, a vehicle roof or a rear seat. Again, the benefits mentioned above are adequate.

The aforementioned object is further achieved by a motor vehicle having a folding table and / or a motor vehicle seat of the type previously disclosed. The corresponding benefits apply adequately.

The following is a brief description of figures of the present invention:

1 shows - in a perspective side view from above - a symbolically illustrated inventive motor vehicle having a symbolically illustrated inventive motor vehicle seat on which a folding table according to the invention is attached.

2 shows details of a carriage and a support plate of the folding table according to the invention in exploded view.

The following is with reference to the non-scale 1 and 2 a detailed, non-prejudicial, in particular limiting, description of embodiments of the present invention. Identical elements are provided with identical reference numerals, unless stated otherwise.

In a motor vehicle 1 there is a motor vehicle seat 5 , on which in turn a known per se frame 10 is attached. The frame has an arm 15 on, which is adjustable, in particular height-adjustable and adjustable in length, is formed and at its the motor vehicle seat 5 far away a folding table 20 wearing. At his a user of the folding table, not shown here 20 facing surface is a decorative cover 25 intended. The decor cover 25 is formed of a carbon fiber reinforced plastic. In the embodiment shown here, the corresponding carbon fiber is based on lignin embedded in a thermoplastic matrix. This affects the folding table 20 not only valuable and visually light, but also follows a resource-saving approach.

As 2 The folding table can be removed 20 a sled 30 , with the arm not shown here 15 is connected, and a carrier plate 35 on. The carrier plate 35 is on the one hand on the sled 30 on tracks 40 slidably attached, on the other hand, it takes the decorative cover only partially shown 25 on. Both the sled 30 as well as the carrier plate 35 are formed in the embodiment shown here from a carbon fiber reinforced plastic, wherein the corresponding carbon fibers are based on lignin, which are embedded in a thermoplastic matrix.

It should be noted that the decor cover 25 , the sled 30 and the carrier plate 35 not only have to have the same orientation of each provided carbon fibers, but that different layer structures can be provided. Thus, for cost reasons, it is particularly advantageous if the carriage is not or not substantially located in a viewing area of a user (not shown) 30 and the carrier plate 35 are formed of a carbon fiber structure with undirected carbon fibers, while the decorative cover 25 with a visually appealing surface, for example as a fabric with an atlas binding.

In addition, it is possible to use the folding table 20 Also to arrange at any other suitable location, which is located in the environment of the user, not shown, and can be reached by this.
