Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle seat having a back cushion capable of being customized,

The present invention relates to a vehicle seat provided with a back cushion that can be customized. More particularly, the present invention relates to a vehicle seat provided with a back cushion which is easily detachable and attachable and can be replaced with various designs according to the driver's or passenger's taste.

In the case of a vehicle seat, it has basically a function of supporting passengers safely and comfortably within a limited space and weight range, and is mainly composed of a back seat (backrest) supporting the driver or a passenger's back, 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. Plastics are known to be advantageous not only because they are 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 a sheet having various aesthetics (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. This trend is not an exception in the automotive field, for example, U.S. Patent No. 7,377,589 discloses a technique for constructing a bottom frame so that the bottom cushion can be replaced with another size.

Therefore, even in a back sheet using a plastic-based frame, there is a demand for a technique capable of reinforcing a customizing element so as to meet such a market tendency.

In the present invention, a back cushion is provided on a plastic-based backsheet frame in order to give various aesthetics (for example, shape, color, pattern and material texture) to the entire backsheet of a vehicle and to meet customization demands of related markets And the back cushion is fixed to the back sheet frame while maintaining proper tightening strength or tightening force, and is easily replaceable, and a vehicle seat including the same.
