Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a vehicle seat.

[Prior art]

As shown in FIG. 5, one type of vehicle seat is a seat bag in which both sides of the seat bag protrude forward and the front end side is formed into a side part that can be rotated inwardly or outwardly or can be extended and retracted, and the back of the seat bag is a back board. There are vehicle seats that are covered.

This type of seat holds both sides of the seated person according to their physique by adjusting the amount of protrusion of each side portion in the left-right direction.

[The problem that the idea attempts to solve]

By the way, in this type of seat, the back board 1 is formed of a hard plate, and is fixed to the back frame 2 at its center to cover the entire back of the seat back 3. If the side portions 3a, 3b are extended inward, gaps will be created between each end portion 1a, 1b of the backboard 1 and each side portion 3a, 3b, detracting from the appearance.

Therefore, an object of the present invention is to prevent the above-mentioned gaps from occurring by fixing each end portion and each side portion of the backboard.

[Means to solve the problem]

The present invention provides a vehicle seat of the type described above, in which at least a portion of the backboard corresponding to the side portions is formed to be flexible, and each of the left and right ends of the backboard is fixed to the outside of each of the side portions. It is characterized by the fact that

[Functions and effects of the idea]

According to this configuration, when each side portion is extended inwardly and outwardly, the backboard bends at a portion corresponding to the side portion and follows each side portion. Therefore, there is no gap between each end of the backboard and each side, and the appearance is not impaired as in the conventional case.

[Embodiment] An embodiment of the present invention will be described below based on the drawings. FIGS. 1 and 2 show the main parts of the seat according to the present invention. The seat is a vehicle seat as shown in FIG.
0b, the back of which is covered with a back board 10c.

As shown in FIGS. 1 to 3, the seat back 10 is composed of a back frame 11, a back plate 12 fixed to the back frame 11, and a cushion pad 13 integrated with an outer skin placed on the plate 12 and fixed to the back frame 11. , each side portion 10 of the plate 12
An airbag 20 is fixed to a portion corresponding to b. The resin plate 21 constituting the outer shell of the airbag 20 is bent, and one plate portion 21a is fixed to the back plate 12, and the other plate portion 21b abuts against the rear surface of the end of the cushion pad 13, and the back plate 21 is bent. plate 12
It is hung on the edge of the Each plate portion 21a,
A bag 22 is stretched between the bags 21b, and air is supplied and discharged to and from the bag 22 through an air pipe 23.

As shown in FIG. 3, the back board 10c is formed into a curved shape that roughly follows the back of the seat back, and the curved portions 14 on both sides are connected to the main body 1.
5, it can be bent in the inward and outward directions. In such a backboard 10c, each hook 16
a to the bag frame 11, and each end thereof is fixed to the ends of the cushion pad 13 and the air bag plate 21 with clips 16b.

In the vehicle seat having such a configuration, the air bag 20 is inflated by supplying and discharging air to and from the air bag 20, and each side portion 10b of the seat bag changes from the state shown in FIG. 1 to the state shown in FIG. The air bag 20 can be expanded inward, and the air bag 20 can be deflated to open each side portion 10.
b can be retracted outward from the state shown in FIG. 2 as shown in FIG. Each side part 10b
When the backboard 10c expands and retreats, each curved portion 14 of the backboard 10c bends in the outward and outward directions, and each side portion 10b
follows the deformation of For this reason, each side portion 10b
There is no possibility that gaps will be formed at each end of the backboard 10c, which will spoil the appearance.

In addition, in the above embodiment, each side portion 10
An example was shown in which the air bag 20 was used as a means for extending and retracting b in the inward and outward directions, but instead, known mechanical, hydraulic, and electrical means for rotating each side part in the inward and outward directions were adopted. can do. Furthermore, the entire backboard may be flexible.
