Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to improvements in seat belt devices for automobiles.

(Prior Art) Seat belts for automobiles are provided, for example, to protect occupants in the event of a collision and to prevent occupants from being ejected from the vehicle.

In order to fulfill these protective functions, the seatbelt must be properly fastened.

It is said that it is best to pass the hook from the shoulder to the chest and waist of the passenger.

Also, depending on the car model, for example, the height of the backrest of an oven-body type car such as an open off-road vehicle may be different from that of a general passenger car in order to have the function of folding the backrest forward to make more use of the interior of the car. It is lower than that.

Therefore, unlike ordinary passenger cars, this type of car requires a special seatbelt hook layout, and also requires that the backrest of the rear seat can be folded down. Ru.

In the conventional seat belt device, in the notchback type rear seats of general passenger cars shown in FIGS. 6 and 7, the retractor 5 is attached to or stored in the rubber cell 12 corresponding to the shoulder area of the passenger. , the seat belt 1 is laid out so that the belt can be stretched in an optimal manner. In addition, 7 is a waist buckle, 3 is a wearable tongue plate, and 4 is a rear seat.

Further, as shown in FIG. 8 (Japanese Utility Model Publication No. 61-24346), some rear seats 4 with a low backrest are provided with a shoulder anchor 13 fixed to a center villa or the like. The retractor 5 is fixed to a side panel of the vehicle body.

In addition, Japanese Utility Model Publication No. 55-30756 discloses a device for fastening the seat belt of a front seat with a high backrest, in which a retractor is built into the seat at a portion corresponding to the height of the passenger's shoulders. something is disclosed.

(Problems to be Solved by the Invention) In the conventional seat belt device described above, FIGS.
What is shown in the figure is a general passenger car seat.
The ideal seatbelt layout has a high seatback, but if the backrest of the rear seat is folded forward to utilize the space inside the vehicle, as in an oven-body vehicle, the seatbelt would be retractor 5. There is a problem in that it is stretched between the attached rear parcel 12 and the outer waist anchor plate (not shown), which obstructs the interior space of the vehicle.

Next, since the seat belt device shown in FIG. 8 is hung from the shoulder anchor 13 fixed to the center wing of the vehicle body onto the shoulder of the occupant, the distance from the shoulder anchor 13 to the shoulder of the occupant becomes long. There is a problem in that the seat belt easily comes off from the shoulder, making it difficult to attach the seat belt in an ideal manner.

For example, when driving off-road in an oven-body vehicle, the vehicle body shakes so much that the seatbelt comes off the occupant's shoulders and hangs around their neck or arm, keeping the occupant safe. You may become unable to do so.

Next, the seat belt device disclosed in Japanese Utility Model Publication No. 55-30756 has a retractor built into the backrest of the front seat, so that the impact force at the time of a collision is received by the backrest of the seat.

However, with seats such as those in oven-body cars, where the backrest of the rear seat is tilted forward, there is a problem in that the backrest cannot absorb the impact force during a collision and cannot fully function as a seatbelt. There is.

The present invention has a sufficient seatbelt function to withstand the impact force at the time of a collision, and provides ideal seatbelt hooking that prevents the seatbelt from coming off the shoulder. It is an object of the present invention to provide a seat belt device that can effectively utilize the interior space of a vehicle.

(Means for Solving the Problems) That is, in the present invention, a retractor is fixed to a side panel of a vehicle body, a shoulder buckle is provided on the shoulder portion of the rear seat, and a waist buckle is provided on the seat portion of the rear seat.

The seat belt is characterized by being equipped with two Kung plates that latch onto the shoulder buckle and waist buckle.

(Function) With this configuration, the seat belt is hung on the shoulder of the occupant via the shoulder tongue plate, thereby providing an ideal seat belt hook. Furthermore, the distance between the shoulder tongue plate and the occupant's shoulder is short, making it difficult for the seat belt to come off the occupant's shoulder. Further, the impact force at the time of a collision is received by a vehicle fixed to a side panel of the vehicle body or by a tractor, and the force does not act on the rear seat.

When folding the rear seat forward, do so by releasing the latch with the shoulder tongue plate. This release causes the seat belt to be held along the side panel of the vehicle body.

(Example) An example of the present invention will be described in detail below. In FIG. 1, a retractor 5 is fixed to a vehicle body side panel 10. As shown in FIG. A shoulder buckle 6 is fixed to the shoulder 4' of the seat 4. This shoulder buckle 6 is the fourth
As shown in the figure, the seat 4 is attached by expanding its shoulder 4', and can be operated from the front using an operating button 6'.

In FIG. 1, reference numeral 7 denotes a waist buckle, and as shown in FIG. 3, it is fixed to the floor or the like by an anchor 14. 11
is an original anchor plate fixed to the vehicle body side panel 10. Two tongue plates, a shoulder tongue plate 2 and a waist tongue plate 3, are attached to the seat belt 1.

As a result, the seat belt 1 is passed from the retractor 5 to the shoulder ring plate 2 latched to the shoulder buckle 6, the waist plate 3 latched to the waist buckle 7, and the primary anchor plate 11. It will be done.

Reference numeral 9 is a clock striker fixed to the side panel 10 of the vehicle body, and is formed in a U-shape as shown in FIG.

8 is a palm pad clock device attached to the side of the seat 4, as shown in FIG.

The operation of this embodiment configured as above will be explained next.

First, as shown in FIG. 5, the seat 1 is fixed to a side panel 10 of a vehicle body or pulled out from a tractor 5, passed through a shoulder tongue plate 2, and hung over the shoulders of an occupant.

Since the shoulder tongue plate 2 is slightly bent and located at the position closest to the shoulder of the seated occupant, the degree of freedom of the seat belt l is reduced and it becomes difficult to come off the shoulder of the occupant. Therefore, the seat belt 1 is an ideal seat belt extending from the shoulder to the chest and waist of the occupant.

In a normal state in which the glossy seat 4 is not tilted forward, the seat belt 1 is handled by operating only the waist tongue plate 3 without removing the shoulder tongue plate 2 from the shoulder buckle 6 (FIG. 1).

In this case, when the lumbar tongue plate 3 is removed from the lumbar buckle 7, the seat belt 1 is stretched from the shoulder tongue plate 2 to the primary anchor plate ll, and the seat belt 1 is tightened when the seat is hooked. It becomes easier to pick up.

Next, when folding the seat 4 forward as shown in FIG. 3, press the operating lever 6' of the shoulder buckle 6 shown in FIG. 4 to release the latch of the shoulder tongue plate 2, and Unlock the rear seat back lock device 8 shown.

Thereby, the seat belt 1 is stretched between the retractor 5 and the primary anchor plate 11, and the seat belt 1 is stretched between the retractor 5 and the primary anchor plate 11, and
It is held along O. Therefore, it does not interfere with the interior space of the vehicle and does not stain the seat belt 1.

Next, the impact force at the time of collision (tensile force of seat belt 1) is:
Fixed to the vehicle side panel 10 or received by a tractor,
The impact force does not act on the rear seat 4.

Therefore, the functions of cushioning the impact force and restraining the occupant are sufficiently maintained.

(Effects of the Invention) As detailed above, according to the present invention, the retractor is fixed to the vehicle body panel, and two tongue plates, a shoulder tongue plate and a waist tongue plate, are provided, and the seat belt is hung at a cross section. This makes it difficult for the seat belt to come off the occupant's shoulders, making it possible to ideally hang the seat.

In addition, the impact force at the time of a collision is fixed to the side panel of the vehicle body or is received by a tractor, so that the force does not act on the seat, so it can be applied to vehicle models that fold the seat forward. This has excellent effects such as bringing the space forward so that it does not interfere with the use of the interior space of the vehicle.
