Description

[Detailed explanation of the idea] This invention relates to a movable through ring.

As a conventional sheet through ring, there is one shown in FIG. 1, for example. In the figure, 1 is the through ring body for passing the seat belt 2 through.
Fixed to the upper end of the arm plate 3, which is a rigid body,
The base end of the arm plate 3 is fixed to a seat frame 4b, which is a part of the seat 4, by welding or the like. (Refer to Japanese Utility Model Application Publication No. 53-24034) However, in the case of such a conventional seat through ring, the through ring body 1 is higher than the upper surface of the seat cushion 4a of the seat 4 due to its relationship with the anchor point. Because of its protruding shape, there was a problem in that the slew ring body 1 would hit the hands or body of the passenger and cause discomfort when changing seats, getting on and off, etc.

This idea was created by focusing on these conventional problems. Under normal conditions, the through-ring body is held so that the seat belt is in the normal attachment path, and when pressed from above, the spring By attaching it to the seat or floor in a movable manner so as to be able to move downward against the pressure, even if an occupant hits the through-ring body when changing seats, the through-ring body will be displaced downward, reducing pain for the occupant. It was designed to do so.

This invention will be explained below based on the drawings.

FIGS. 2 and 3 are diagrams showing an embodiment of this invention.

Note that the same members as those in the prior art are designated by the same reference numerals and their explanations will be omitted.

First, to explain the structure, the through ring main body 1 is fixed to the free end of a holding plate 5, and the base end of this holding plate 5 is fixed to a base plate 6 fixed to the seat frame 4b, which is a part of the seat 4. is rotatably supported via a support pin 7. An arcuate guide hole 8 centered around the support pin 7 is formed in the holding plate 5, and a stopper pin 9 implanted in the base plate 6 engages with this guide hole 8, so that the side portion of the stopper pin 9 engages with the guide hole 8. When the through ring main body 1 comes into contact with the lower end 8a of the guide hole 8, the through ring main body 1 is in a position where the seat belt 2 is placed on the normal mounting path. A doglegged spring 10 is attached to the support pin 7,
One end of this spring 10 is locked to a locking piece 11 formed on the base plate 6, and the other end is locked to the upper end 8b of the guide hole 8. Under normal conditions, the through ring main body 1 is held so that the seat belt 2 is in the normal attachment path, and is designed to rotate downward against the spring 10 only when pressed from above. .

Next, the action will be explained.

When the passenger's body hits the through ring main body 1, a downward force is applied to the through ring main body 1, and the through ring main body 1 is rotated downward about the support pin 7 against the spring 10. As a result, discomfort such as pain for the occupant can be reduced. When the occupant's body separates from the through-ring main body 1, the through-ring main body 1 returns to its old position again by the elastic force of the spring 10, and in this normal state, the seat belt 2 is held in the normal attachment path.

FIG. 4 shows another embodiment.

In this embodiment, the through ring main body 1 is fixed to the upper end of the holding shaft 12, and the holding shaft 1
2 is slidably held by an outer cylinder 13 fixed to the seat frame 4b, and a compression spring 14 is installed between the outer cylinder 13 and the through ring main body 1.
is inserted, the through ring main body 1 is urged upward, and a stopper flange 15 is formed at the end of the holding shaft 12, and the stopper flange 15 is in a normal state in contact with the lower end surface of the outer cylinder 13. Normally, the through ring body 1 is held so that the seat belt 2 is properly attached, and when pressed from above as shown by the arrow in FIG. 5, it is displaced downward against the spring 14. It's summery. Even if the occupant hits this through ring body 1, he or she will not feel any pain. It should be noted that the stopper flange 15 is formed so as to be able to abut and hold the lower end of the outer cylinder 13 against the tension applied when the seat belt is worn.

FIGS. 6 and 7 show still another embodiment of the present invention. In this embodiment, the through ring main body 1 is fixed to the upper end of the holding stay 16, and the holding stay 1
The lower end of the through ring body 1 is slidably held by a guide portion 17 fixed to the seat frame 4b, and a compression spring 18 housed in the guide portion 17 causes the through ring body 1 to hold the seat belt 2 in a normal state. The through-ring body 1 is held in a normal mounting path, and is displaced downward against a spring 18 when the through-ring body 1 is pressed from above. Even if the occupant hits the through ring body 1, he or she will not feel any pain.

In the figure, 16a is a flange provided at the lower end of the holding stay 16, and 17a is a stopper for preventing the flange 16a from coming off upward. Further, 16b is a convex portion provided on the holding stay 16 and has the same function as a flange.

In each of the above embodiments, the seat 4 is of a sliding type, but the present invention is not limited to this, and the seat 4 may be of a fixed type. In this case, the base plate 6 and the outer The tube 13 and the guide portion 17 are fixed to a floor (not shown).

As explained above, according to this idea,
Its structure is such that the main body of the through ring is movably attached to the seat or floor so that the seat belt is held in the normal attachment path under normal conditions, and is displaced downward against the spring when pressed from above. Therefore, even if the occupant's body hits the through-ring body when changing seats or getting on and off, the through-ring body is displaced downward, thereby alleviating pain and discomfort.
