Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle seat having a mesh type string member,

The present invention relates to a vehicle seat provided with a mesh type string member. More particularly, the present invention relates to a back sheet having a mesh-type string member capable of being customized on a plastic-based back sheet frame, and a vehicle seat comprising the back sheet.

In the case of a vehicle seat, it has basically a function to securely and comfortably support a passenger within a limited space and weight range, and is largely composed of a seat back supporting a driver or a passenger, A headrest that reduces the impact on the passengers' head, and a cushion that rests on the buttocks. Normally, a seat cover or a trim cover which covers the surface of the sheet and serves as a package, a surface, and an outer shape is provided.

In this connection, it is known that the body of the vehicle occupies about 20% of the weight of the vehicle, about 11% for the interior, and about 7% for the exterior and glass, and about 60 to 180 kg per seat for the interior of the vehicle . At this time, in the case of a sheet frame corresponding to a skeleton of a sheet, a material such as steel (or steel) has been used in the past. Steel can provide the stiffness and impact strength required of the sheet, but the sheet made of steel is composed of several discrete parts, which increases the cost of sheet manufacture.

Particularly, since the weight ratio of the seat to the entire vehicle is the next member of the car body, there is a growing demand for weight reduction of the seat for improving fuel economy. On the other hand, in recent years, a sheet frame technique using a magnesium sheet has been utilized, which can significantly reduce the weight as compared with steel used in the past, but there is a limit depending on the metal material.

Under these technical backgrounds, attempts have been actively made to manufacture vehicle seats from lightweight materials such as plastics. Typically, plastic is known to be advantageous not only because it is much lighter than steel, but also because the features of the sheet can be incorporated into the plastic frame. In particular, plastic-based sheets have the advantage that they can be produced through a single injection molding process.

In the main sheet companies, a composite material composed of a thermoplastic matrix and a reinforcing material (glass fiber, carbon fiber, etc.) is formed into a single piece, a sheet-back frame and a sheet-back cover manufactured from the composite material are combined, Although the plastic frame is joined to the frame to reduce the weight of the sheet, it is not applied to the entirety of the back sheet made of plastic (U.S. Patent No. 6,679,558, U.S. Patent Application Nos. 2009/0058166 and 2008/180783 Etc).

Further, it is also known to combine reinforcing members in addition to plastic frames in order to compensate for the fact that plastic-based frames have lower mechanical properties or strength than metal-based frames (WO2013 / 021485, WO2013 / 021484, WO2013 / 021482, etc.).

In recent years, BASF has developed a plastic sheet frame material (trade name: Ultramid) based on a polyamide-based resin having improved mechanical properties with high rigidity, and has been applied to an electric vehicle.

In this way, the plastic-based seat frame having improved mechanical properties can be significantly reduced in weight as compared with a conventional metal (steel) -based back sheet frame, and at the same time, It is possible to reduce the space occupied by the existing seat to a considerable extent and to exert a favorable influence on the expansion of the space inside the vehicle.

In the above-described plastic-based technology, in order to utilize the advantage of making the entire sheet thinner than the prior art and widening the space inside the vehicle, it is necessary to use a sheet cover , It may be advantageous not to use leather or various fabric materials). However, when the plastic frame itself is manufactured in such a manner that it is exposed to the outside, there is a limit in constructing the back sheet having a variety of aesthetic (color, etc.) in a manner suited to the driver's preference.

Furthermore, recently, in the field of electronic products such as smart phones, customizing trends have been established in which accessories having various colors and / or shapes are manufactured and replaced according to consumers' individuality and preferences, and the size of related market is also increasing.

On the other hand, in the conventional backsheet for a vehicle, the back portion of the driver or the passenger comes into contact with the back sheet surface made of leather or fabric, causing sweating in the summer season, and it is difficult to maintain the comfort during operation. In this regard, in the field of office or domestic chairs, there is also known a technique of improving the comfort by forming the back sheet surface in the form of a mesh (Korean Patent Laid-open No. 2010-95548, etc.), but generally a leather or fabric cover sheet It is difficult to find examples applied in the field of backsheets for automobiles covered with trim sheets. At most, there is only an example in which a cloth in mesh form is interposed between the back sheet and the driver or passenger.

In particular, no technology has been found that incorporates a mesh type member that can be customized to give various aesthetics in a plastic-based back sheet frame.

In the present invention, a mesh type member capable of imparting various aesthetic feelings (for example, shape, color, pattern and material texture) to the entire backsheet while improving comfort can meet the customization demand of a related market, (Integrated) in a seat frame and a vehicle seat including the same.
