Description

[Detailed Description of the Invention] The present invention relates to a back garnish for a vehicle seat, and more specifically, it is attached to the back side of the seat back and serves as a cover and decoration for the back side of the seat back. Concerning Bakuganitshu.

Conventionally, various bag garnishes have been used to cover the back side of the seat bag of a seat and for decorative purposes. These back garnishes are formed by vacuum forming or stamping molding a sheet of synthetic resin material with a certain wall thickness. Therefore, in order to obtain the necessary strength and rigidity, a relatively thick sheet of synthetic resin material is used to obtain the necessary strength and rigidity. Synthetic resin materials were required. In addition, as a measure for rigidity, beads are used within the allowable range for modeling, but this is not a sufficient measure and it is necessary to use synthetic resin materials with a wall thickness that corresponds to the required rigidity, which increases material costs. However, it also has the disadvantage of increasing molding time and processing costs.Also, when a rear seat occupant collides with the part of the back garnish that faces the seat back frame, it is difficult to prevent the back garnish from colliding directly with the seat back frame. There was a risk that the impact force would be applied and the occupants in the rear seats would be injured.

The purpose of this invention is to make the parts that require relatively rigidity double-layered, and to make the wall thickness of other parts sufficiently thin, which can reduce material costs and improve work efficiency. In addition, we provide a back garnish for a vehicle seat that is highly safe and can act as a buffer and prevent injury to the rear seat occupant in the event that the rear seat occupant collides with the portion facing the seat back frame. This will become clear from the detailed description below with reference to the drawings.

1, 2 and 3 schematically show an embodiment of a back garnish for a vehicle seat according to the present invention.
is a base material 2 formed by blow molding a synthetic resin material.
, a cushioning material 3 made of foamed synthetic resin or the like bonded to the outer circumferential surface of the base material 2, and a skin material 4 made of synthetic resin, woven fabric, etc. bonded to the outer circumference of the cushioning material 3. ing. As shown in FIG. 1, on the front side of the bag garnish 1, a recess 11 is formed near the center, and newspapers, newspapers, etc.
A storage section 12 for storing magazines and the like is formed of the same material as the cover material 4 or of a net-like material.

A seat back frame 2 is provided on the back side of the base material 2.
A semi-circular groove 13 is formed in the abutting portion of 1 along the vertical direction of both sides, and the portion where the groove 13 is formed is respectively formed as a space 14 as shown in FIG. In this embodiment, this space 1
4 is not formed continuously in the vertical direction on both sides of the base material 2, but a concave part 15 is formed in the middle part when viewed from the back side, and a plurality of spaces 14 are formed. However, the space portion 14 may be formed continuously in the vertical direction. The space portion 14 can be easily formed during blow molding of the base material 2. In this embodiment, the hollow part 14 is not formed in the upper part of the base material 2, but the hollow part 14 is formed along the upper edge.
It is also possible to form.

Furthermore, in this embodiment, the bag garnish 1 is shown to be attached to correspond to the shape of the back side of the seat bag so as to cover almost the entire surface of the back side of the seat bag. It will be obvious that the present invention can be similarly applied to a back garnish that covers the upper part.

The above is the configuration of the back garnish for a vehicle seat according to the present invention. According to this configuration, the portion of the back garnish that requires relatively rigidity is formed of a double-layered base material. However, the wall thickness of other parts can be made thinner than when vacuum forming or stamping molding a sheet-like synthetic resin material, which reduces the amount of synthetic resin material used and improves work efficiency. Furthermore, in the event that an occupant collides with the space in the back garnish facing the seat back frame, the space in the base material acts as a buffer, and the back seat occupant Since there is no direct collision with the seat back frame, it is possible to obtain a back garnish for a vehicle seat with excellent safety without the risk of injury.
