Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement on the buckle side of a seat belt installed in the seats of vehicles such as automobiles and aircraft. More specifically, the present invention relates to a retractable seat belt buckle suitable for opening onto a vehicle seat.

(Prior Art) Seat belt buckles conventionally used in automobile seats are, for example, as shown in Fig. 4.
A configuration in which the buckle 4 attached to the end of the belt 5 is simply left on the seat cushion 3 of the seat 1 is commonly used, but this is unsightly and also tends to move due to vehicle vibrations and collide with the occupant. Otherwise, sitting on it may cause discomfort.

Therefore, in order to improve this drawback, the
No. 146750 proposes a retractable seat belt buckle having the structure shown in FIG.

This buckle is provided with a recess 6 at an appropriate position of the seat cushion 3. When the seat belt is not in use, the buckle 4 and the belt 5 are stored in the recess 6, and the recess 6 is covered with a lid 7. When the seat belt is in use, the buckle 4 and the belt 5 are stored in the recess 6.
There is a configuration in which the buckle 4 is pulled out and used by opening the buckle.

(Problems to be Solved by the Present Invention) However, this buckle storage mechanism has a structure in which when the buckle 4 is not in use, it is stored in the recess 6 and then the recess 6 is covered with the lid 7. Therefore, the buckle 4 does not move and looks good, but a problem arises when the buckle 4 is used. That is, when using the buckle 4, the tower rider must first open the lid 7, then insert his hand into the narrow space 6 and pull out the buckle 4, making the operation complicated. Also, storing the Buckle 4 will not work if you don't fold the belt properly, as the lid will pop up.

The object of the present invention is to provide a retractable seat belt buckle that looks good and is very easy to handle.

(Means for Solving the Problems) In order to achieve the above object, the retractable seat belt buckle of the present invention has a lid that is formed into an L shape and swings around its corner, and a seat of the seat. A storage case that is embedded and fixed at an appropriate position in a cushion, and the lid is attached to be swingable in the vertical direction, and a cylindrical surface substantially parallel to the rocking locus of the lid extends from the bottom to the opening. and a buckle stored in the case and placed on the lower side of the lid, so that when the lid is closed, the outer surface of the lid and the seat cushion form the same surface and when the lid is opened. At times, the buckle is configured to appear on the seat cushion.

(Example) Hereinafter, the configuration of the present invention will be described in detail based on an example shown in the drawings.

FIG. 1 illustrates the stored state of the retractable buckle according to the present invention using a central vertical sectional view. This retractable buckle includes a lid 10 formed into an L-shape by a plate-like member, a buckle 4 placed on the lower side 10a of the lid 10, and the lid 10 swingably attached. It consists of a storage case 11 embedded in a seat cushion 3.

The lid 10 having the notch 12 is formed of a member having a predetermined strength, such as a steel plate bent into an L shape, a casting, or a plastic molding. The molded member of the lid 10 is not particularly limited as long as it is not deformed or damaged by the impact force at the time of a collision or rear-end collision, but plastics, aluminum alloys, etc. are preferred. In addition, a mounting hole is drilled in the corner of the lid 10 to allow the lid 10 to vibrate freely in the storage case 11. is attached to the storage case 11.

The buckle 4 has a latch function that can grip and fix a belt tongue (not shown) attached to a belt (not shown), and in this embodiment, it is fixed to the lower side 10a of the lid 10. .

The storage case 11 is embedded in the rear part of the seat cushion 3, and is configured to swingably support and store the lid 10. The bottom portion 11a of the storage case 11 has a curved cylindrical surface so as not to hinder the swinging of the lid 10 and to form no gap between the lid 10 and the lid 10. The lid 10 is attached to the storage case 11 using the screws 13 as described above.
It is carried out by.

In a buckle with this configuration, when storing the lid
By rotating the seat cushion 3 downward, the outer surfaces of the seat cushion 3 and the lid 10 form the same surface, and when in use, by inserting a finger into the notch 12 and rotating the lid 10 upward, the seat cushion 3 and the outer surface of the lid 10 are rotated upward. 4 appears on seat cushion 3. Furthermore, if a stopper mechanism using a spring member or the like is provided at an appropriate position on the lid 10 or the storage case 11, the storage state and the use state can be reliably maintained.

In this embodiment, the shape of the retractable case 11 is
Although only a case in which 1a is curved has been described, the storage case is not limited to this shape, and any shape may be used as long as it does not prevent the lid 5 from rotating. Furthermore, it is preferable that the strength for fixing the storage case 11 in the embedding and the strength for attaching the storage case 11 and the lid 10 to each other are such that they do not come off due to impact during a collision or a rear-end collision.

(Effects) As is clear from the above description, the retractable seat belt buckle of the present invention has a lid that is formed into an L shape and swings around its corner, and a lid that is attached to an appropriate position on the seat cushion of the seat. A storage case in which the lid is installed to be buried and fixed so as to be swingable in the vertical direction, and a cylindrical surface substantially parallel to the rocking locus of the lid is provided with a cylindrical surface extending from the bottom to the opening; and a buckle placed on the lower side of the lid, so that when the lid is closed, the outer surface of the lid and the seat cushion form the same surface, and when the lid is opened, the buckle is placed on the seat cushion. Since the buckle is configured so that it appears on the cushion, it can be stored in the storage case when not in use, giving it a very good appearance and preventing the buckle from moving due to vibration etc. will not cause any discomfort. Furthermore, when in use, simply by rotating the lid upward, the buckle simultaneously appears on the seat cushion, making it ready for use.
In other words, it is possible to improve usage efficiency.
