Description

[Detailed explanation of the idea] The present invention relates to an automobile rear seat device.

2. Description of the Related Art Conventionally, some rear seats of automobiles have a side cushion for a backrest that is juxtaposed to the side of a reclining seat back and protrudes from the side wall of the vehicle body toward the seat back. However, when the seatback is tilted backwards, a step is created between the seatback and the side cushion, which loses the sense of unity between the seatback and the side cushion, spoiling the aesthetics of the interior of the vehicle, and impairing the passenger's safety. There is a problem in that the back hits the stepped portion, resulting in poor riding comfort.

On the other hand, as disclosed in Japanese Utility Model Application Publication No. 151028/1983, a tilting angle adjusting means is attached to the vehicle body on the side of the seat back to improve the riding comfort of the rear seat. Although there are devices that engage with the adjustment means to adjust the tilt angle in stages, no countermeasures have been taken for the problem of the level difference that occurs in the side cushion portion.

In view of the above, the present invention engages a seat back and a side cushion, and elastically deforms the side cushion as the seat back tilts rearward, thereby deforming the side edge of the side cushion on the seat back side. An object of the present invention is to provide a rear seat device for an automobile in which the rear seat is tilted together with the seat back, thereby improving the aesthetic appearance of the interior of the vehicle and the riding comfort for the occupants.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings.

Reference numeral 1 designates a rear seat of an automobile, which is composed of a seat bottom 2 fixed to the floor of the vehicle body, and a seat back 3 attached to the floor or the seat bottom 2 so as to be tiltable back and forth. , the side trim 5 is stretched. Further, at the rear end of the side trim 5, a side cushion 6 for a backrest corresponding to the seat back 3 is provided to protrude toward the seat back side.

The seat bag 3 and the side cushion 6 are arranged side by side with their front and upper surfaces flush with the road surface, and their upper ends are engaged by an engaging means 7. Shion 6
is configured such that it can be twisted and deformed rearward by using side portions 6a and lower side portions 6b connected to the side trim 5 as fixed sides.

That is, in the structure of the side trim 5 and the side cushion 6 shown in FIG. 2, 8 is a vertical core bar provided at the end of the side cushion 6 on the seat back side, and is made of a vertically elongated rectangular frame made of spring steel wire. The lower end is fixed to the vehicle body floor (not shown) with bolts 9. This vertical core bar 8
An upper core bar 10 and a lower core bar 11, which extend from the side trim side by bending the corner formed by the side trim 5 and the side cushion 6, are fixed to the upper and lower end parts. The upper core bar 10 is 1
A spring steel wire is bent into a U-shape and run vertically in parallel, and the bent U-shaped end 10a slightly protrudes from the vertical core bar 8 toward the seat back side. Then, a zigzag spring 12 is stretched around the frame of the vertical core bar 8, and a zigzag spring 13 similar to the above is also installed between the upper core bar 10 and the lower core bar 11 of the side cushion 6. The zigzag spring 13 is stretched along its outer shape, and a skin 15 is stretched on the outside of the zigzag spring 13 via a sponge material 14. The end portion 10a of the upper core bar 10 that protrudes from the vertical core bar 8 constitutes a convex portion 16 that protrudes from the side surface of the side cushion 6 on the seat back side, as shown in FIG. Therefore, when a rearward pressing force is applied to the upper end of the side cushion 6 on the side of the seat back 3, the vertical core bar 8 tilts rearward using the lower end fixed with the bolt 9 as a fulcrum, and the upper core bar 10 moves toward the side. The corner formed by the trim 5 and the side cushion 6 is used as a fulcrum to rotate and deform rearward, and as a result, the side cushion 6 is elastically deformed (torsionally deformed), and when the pressing force is released, the vertical core bar 8 and The spring force of the upper core metal 10 returns it to its original position.

On the other hand, the seat bag 3, as shown in FIG.
A back plate 17 is layered with a urethane material 18 and a sponge material 19 and covered with a skin 20, and a recess 21 corresponding to the projection 16 of the side cushion 6 is formed at the upper end of the back surface. part 16 and recess 2
1 constitutes the engagement means 7.

In addition, in FIG. 2, 22 is a board of the side trim 5.

In the above structure, when the seat back 3 is tilted rearward, the side cushion 6 is elastically deformed (torsionally deformed) by the rearward pressing force at the convex portion 16 engaged with the seat back 3, and the seat back of the side cushion 6 is tilted backward. The side edge portion 6c is tilted rearward together with the seat back 3 at approximately the same angle. Therefore, there is no difference in level between the seat back 3 and the side cushion 6. Further, when the seat back 3 is returned to its original position, the side cushion 6 is also returned to its original position by the spring force of the vertical core bar 8 and the upper core bar 10.

As described above, according to the present invention, the seat back and the side cushion are engaged, and when the seat back is tilted backwards, the side edges of the side cushion are tilted together with the seat back. It is possible to always form a gentle seat surface with the front surface of the cushion, which has the excellent effect of improving the aesthetics of the vehicle interior and improving the ride comfort.
