Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a seat cushion used as a seating portion of a seat in an automobile or the like, and particularly to a seat cushion in which a slit is formed and a webbing is inserted through the slit.

[Prior Art] Automobiles are equipped with seatbelt devices equipped with occupant restraint webbing for the purpose of protecting occupants. A buckle device or tongue plate is attached to one end of the webbing, and the other end is fixed to a heavy structure by passing around the side of the seat or passing between a seat cushion and a seat back. In this case, in order to prevent the webbing from slipping off the seat cushion due to vibrations of the vehicle body, movement of the occupant, etc., a loop-shaped seatbelt holding device has been proposed that is provided at the side or rear part of the seat cushion, or at the lower end of the seat back. Utsukai Showa 51-1064
No. 21, see Utility Model Publication No. 58-20439).

However, in the mounting structure of this seat belt device, -
Since it can only be installed on a required seat or a structure where the seat back and seat cushion are separated, that is, a structure where there is a gap between the two, it cannot be installed on a seat with a structure where the seat cushion and the seat back are integrally continuous, especially There is a problem in that it cannot be applied to bench seats used in the rear seats of vehicles. In addition, in the mounting structure of these seat belt devices, the webbing is left on the seat cushion even when the seat belt device is not in use, resulting in a poor appearance, and furthermore, the location of the buckle device and tongue plate is uncertain. It was inconvenient to wear.

For this reason, a seat cushion has been devised in which a slit is formed and an intermediate portion of the webbing is inserted into the slit. With this seat cushion, the middle part of the webbing is inserted into the slit, and only the buckle device and tongue plate can be placed at the slit opening position, which is convenient when attaching the webbing, and does not interfere with the occupant's appearance. It has the advantage of being good.

However, due to the structure of the seat cushion, which is made of a flexible material, there is a possibility that the buckle device or the tongue plate may slip down into the slit due to vibrations of the vehicle body or deflection caused by the occupant sitting on the seat. Furthermore, if the slit is made smaller in order to prevent this, the work of passing the buckle device etc. through during assembly becomes complicated.

[Problems to be Solved by the Invention] Taking the above-mentioned main points into consideration, the present invention provides a seat cushion in which the buckle device and tongue plate attached to the webbing do not slip off from the slit and can always be placed in a predetermined position. That is the purpose.

[Means for Solving the Problems] In the seat cushion according to the present invention, a flexible holder is attached near the slit for passage of the webbing, buckle device, etc. This flexible holder can be made of a cloth material used as webbing, a more flexible cloth material, a string, etc., and has a size that allows the webbing and the seat belt engaging means for attaching the webbing to be inserted therethrough. Further, the flexible holder may be an elastic body that can be expanded and contracted, such as a rubber band or a belt-like rubber band.The seatbelt engagement means is a buckle or a tongue plate that engages with the buckle, and is attached to the tip of the webbing. .

[Operation] In the seat cushion configured as described above, the webbing is inserted through the slit from below to above, guided by the buckle device and the tongue plate. Additionally, the webbing is threaded through the flexible holder.

After the webbing is inserted, the flexible holder flexes and bends to hold the seat back, so the buckle device and tongue plate are held by the flexible holder and do not slip down into the slit.

[Example] FIG. 1 shows a rear seat of an automobile to which a seat cushion 10 according to the present invention is applied.

In this seat, a seat back 11 is erected at the rear end of a seat cushion 10, and a slit 12 is formed in the rear part of the seat cushion 10 so as to pass through the seat cushion 10 in the vertical direction. The slits are provided on both sides of the seated position of each occupant, and the webbing 14 is inserted through them from below to above.

One end of the webbing 14 is an anchor play) 15 and pol)
It is fixed to the vehicle body via 16. A buckle device 18 or a tongue plate 20 is attached to the other end, and the buckle device 18 and the tongue plate 20 engage with each other so that the pair of webbings 14 can be attached to the occupant.

A flexible holder 22 is provided near the vehicle rear side of each slit 12.
are arranged respectively. The flexible holder 22 is made of flexible cloth and has an annular shape, and both ends thereof are fixed to the seat cushion 10 as shown in FIG. That is, both ends are sandwiched between the overlapping parts of the outer skin 10A and IOB of the seat cushion 10, and then sewn to these overlapping parts. The flexible holder 22 is attached to the buckle device 1 when its diameter is expanded.
The webbing 14 inserted through the slit 12 is inserted into the flexible holder 22, the length of which is determined to be slightly larger than the maximum cross-sectional area of the tongue plate (8 and tongue play) 20.
A buckle device 18 or a tongue plate 20 is inserted therethrough.

In this case, the material and mounting method of the flexible holder 22 are not limited to the above-described configuration, but any material that can securely hold the webbing 14 and does not cause discomfort even if it interferes with the passenger may be used. Often, the elastic body 1 may be made of a flexible material such as a synthetic resin such as rubber, or may be attached using adhesive or the like.

Next, the operation of this embodiment will be explained.

Before assembling the seat cushion 10 to the vehicle body, a flexible holder 22 is sewn in advance, and the webbing 14, whose one end is fixed to the vehicle body with a port 16, is inserted from below the slit 12, and the webbing 14 is inserted through the slit 12 as shown in FIG. Buckle attachment 3118 as shown in
and the tongue plate 20 are inserted into the flexible holder 22, respectively. In this case, the opening 24 formed by the flexible holder 22 is slightly larger than the buckle device 18 and the tongue plate 20 so that the flexible holder 22
By enlarging the diameter to the maximum, these can be easily inserted.

Although it may be used in this state, if the webbing 4 is pulled back a small amount into the slit 12 as shown in FIG.
The flexible holder 22 is bent and bent toward the slit 12 to hold the buckle device 18 or the tongue plate 20 vertically.

Furthermore, after that, the seat cushion 10 is bent due to seating of the first occupant, vibration of the vehicle body, etc., and the webbing 1 is inserted into the slit 12.
When a force is applied to pull back 4, the flexible holder 22
Because it is bent and bent, the area of the opening 24 is reduced, and the ear part 26 is buckled (W18 or tongue play) 2
Therefore, the buckle device 18 (or tongue plate) 20 will not slip down into the slit 12, and therefore the buckle device 18 will always remain in place.
Alternatively, the tongue plate 20 can be placed near the slit 12. On the other hand, insert webbing 14 into slit 1.
When pulling out from the flexible holder 2, use the flexible holder 2 as necessary.
2 to the state shown in FIG. 3, the area of the opening 24 of the flexible holder 22 increases again and the engagement is released, so that the flexible holder 22 can be easily pulled out. In particular, since the buckle device 18 and tongue plate 20 are always placed near the slit 12, the occupant can easily install the buckle device N18. Tongue plate 2
Can grasp 0.

As shown in FIG. 4, the flexible holder 22 preferably has a length such that the buckle device 18 does not enter into the slit 12, or even if it does, the entire buckle device 18 is not buried within the slit 12.

In the above embodiment, the buckle device 18 and the webbing 14 to which the tongue plate 20 is attached are both inserted through the slit 12 of the seat cushion 10.
The webbing 14 to which the webbing 14 is attached may be inserted into the slit 12. For example, the tongue plate 20 may be made movable to the middle of the long webbing 14, and both ends of the webbing 14 may be locked to the vehicle body. According to this, the webbing to which the tongue plate 20 is attached becomes a continuous formation of shoulder webbing and lap webbing. Further, one end of this continuous webbing may be wound up with a winding device.

[Effects of the Invention] As explained above, the seat cushion according to the present invention has the following effects:
A seat cushion in which a slit is formed through which a middle portion of webbing is inserted, one end of which is fixed to the vehicle body and a buckle device or a tongue plate that engages with the buckle device is attached to the other end, the webbing is inserted into the vicinity of the slit. Since a flexible holder is provided to hold the webbing, it is easy to insert the webbing, and after insertion, the buckle device or tongue plate is prevented from slipping into the slit. This has an excellent effect in that the tongue plate can be erected and held in a predetermined position.
