Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to improvement of a seat belt device for an automobile.

(Prior art) In the case of an automobile seat belt device that supports the shoulder and lumbar regions of an occupant seated in a seat, the seat belt is usually pulled out from a retractor attached to the lower side of the vehicle body, and is pulled out from the upper side of the vehicle body. After passing through a guide member attached to the guide member (after being folded back by the guide member), the tip end thereof is attached to the lower side of the vehicle body near the retractor (see Japanese Utility Model Publication No. 57-124457). Then, the tongue plate provided in the support belt part of the seat belt between the guide member and the seat belt tip fixing part is engaged with the buckle attached to the lower part of the vehicle body at approximately the center in the vehicle width direction. The shoulder portion of the occupant is supported in a cross-over manner by the support belt portion on the guide member side side of the tongue plate, while the support belt portion on the tip fixing portion side side of the tongue plate supports the shoulder portion of the occupant in a cross-over manner. It is designed to support the passenger's waist.

In the case of such a seat belt device for a car, the support belt part is attached to the seat belt so that the seat belt, especially the support belt part, can be easily pulled when the occupant seated on the seat puts on the seat belt. It is preferable to set the positions of the guide member and the distal end fixing portion so that the guide member and the distal end fixing portion do not move further backward than the seat back.

However, when used for a seat that has a large amount of longitudinal sliding, such as an intermediate seat located in the middle of a so-called one-box car in the longitudinal direction of the vehicle, depending on the sliding position,
The above-mentioned support belt is located far back than the seat, and as a result, in order to pull the seatbelt on, you have to turn half your body and extend your hand far backwards, making it difficult to put on the seatbelt. The problem arises that it becomes extremely troublesome. In particular, the retractor, the guide member, and the seatbelt end fixing part are attached to the strong pillar part of the vehicle body, and the seatbelt is generally straight in the vertical direction when not in use. Therefore, the above-mentioned problems occur.

(Purpose of the invention) The present invention was developed in consideration of the above-mentioned circumstances, and does not significantly change the mounting position of the seatbelt device, that is, the position of the part that takes charge of the tensile force applied to the seatbelt, from the conventional one. ,
To provide a seat belt device for an automobile, which allows the seat belt to be easily tightened.

(Structure of the invention) In order to achieve the above-mentioned object, in the present invention, a flexible wire is used to position the distal end fixing portion of the seat belt on the side of the seat.

Specifically, one end of the flexible wire is
The flexible wire is attached to the lower side of the vehicle body near the retractor, and the other end of the flexible wire is extended forward in the direction of the seating posture of the seat as a free end. It is designed to be attached to the free end.

With this configuration, the portion of the seat belt that is attached to the free end of the flexible wire is located on the side of the seat, so that the occupant can easily pull the seat belt toward his or her hand.

(Example) In Fig. 1 and Fig. 2, 1 is a one-box type car, and the side of the car is marked with X, Y, Z.
It is said to have three side windows. This automobile 1 includes three rows of seats: a front seat 2, an intermediate seat 3, and a rear seat 4. The front seat 2 includes a driver's seat side seat 2A and a passenger seat side seat 2B.
The middle seat 3 and the rear seat 4 are each designed to seat three people. The intermediate seat 2 is of a so-called rotating type, with the occupant seated in a forward-facing position facing the front of the vehicle body (the position shown by the dashed line in FIG. 1 and FIG. The position indicated by the solid line in Figure 1) can be selectively taken.

As described above, although the automobile 1 is designed to seat nine people, a seat belt device is attached to each occupant. That is, among sheets 2 and 3,
The seat belt device A for a total of five passengers, two passengers seated in the center in the vehicle width direction and three passengers seated in the rear seat 4, is of a type that supports only the waist of each passenger. The seat belt devices for the other four passengers are of a type that supports both the shoulder and lumbar regions of the occupants. The seat belt device for the intermediate seat 3 is provided separately for the forward-facing position and the rear-facing position, and in this embodiment, as shown in FIG. The seat belt device B is according to the present invention, and the seat belt device C is for the intermediate seat 3 in the rear facing position.
The seat belt device D for two people located at the end of the front seat 2 in the vehicle width direction is the same as the conventional one.

To explain the seat belt device B for the intermediate seat 3 in the forward-facing position, the side window Y
On the side of the vehicle body between and Z, that is, the pillar part 5,
A retractor 7 is rotatably attached to the lower part of the retractor 7 by an anchor bolt 6, and a guide member 9 is rotatably attached to the upper part thereof by an anchor bolt 8. Further, near the retractor 7, one end portion of the flexible wire 10 is rotatably attached (co-tightened) by an anchor bolt 6 for attaching the retractor. The other end of this flexible wire 10 is a free end 10a.
, extending forward in the direction of the seating posture relative to the front of the vehicle body, that is, the intermediate seat 3 in the forward-facing position,
A ring-shaped bracket 16 is rotatably attached to the free end 10a with a pin or the like. When the intermediate sheet 3 is at its forward and backward sliding position, the free end portion 10a of the flexible wire 10 is positioned on the side of the intermediate sheet.

As is known, the retractor 7 is equipped with a winding roller inside and has a function of winding up the seatbelt 11.The seatbelt 11 pulled out from the retractor 7 extends upward at one end and is attached to a guide member. It passes through the guide ring 9a of No. 9 and extends downward after being folded back, and its tip is attached to the bracket 16 with bolts, nuts, etc. Of course, the anchor bolts 6 and 8 are attached to the pillar portion 5, which has excellent strength, and in particular, the anchor bolt 6 is installed at or near the connecting portion between the pillar portion 5 and the side sill portion or the frame. Sufficient mounting strength is ensured.

The portion of the seat belt 11 between the guide member 9 and the bracket 16 (free end portion 10a of the flexible wire 10) serving as its tip fixing portion constitutes a support belt 11a that supports the occupant. A tongue plate 12 is slidably attached to the support belt portion 11a. This tongue plate 12 is attached to and detached from a buckle 13, and this buckle 13 is attached to a rotating base 15 of an intermediate seat 3 attached to a lower part of the vehicle body (in the embodiment, a floor panel 14) at an intermediate portion in the vehicle width direction. ) is installed. Of course, when this tongue plate 12 is engaged with the buckle 13,
For an occupant seated on the intermediate seat 3 in the forward-facing position, the guide member 9 is moved from the tongue plate 12.
The support belt 11a on the side supports the shoulder part of the passenger in a cross-over manner, and the support belt part 11a from the tongue plate 12 to the bracket 16 as the tip fixing part supports the waist part of the passenger. I support it.

Therefore, when the occupant seated on the intermediate seat 3 in the forward-facing position wears the seat belt 11, the occupant must first fasten the seat belt 11 (support belt portion 11a) near the free end 10a of the flexible wire 10 nearby. By pulling, the support belt portion 11a of the seat belt 11 is pulled closer, and after this, the pulled support belt portion 11a
The tongue plate 12 provided on the buckle 1
3 should be engaged. When this seat belt 11 is worn, the flexible wire 10
is easily curved along the tension direction of the seat belt 11, providing good wearability and preventing undue twisting force from acting on it.

Although the embodiments have been described above, the present invention is not limited to this. For example, the seat belt device C for the intermediate seat 3 in the rear facing position or the seat belt device D for the front seat 2 may be used as a seat belt device according to the present invention. It may also be B. Further, the present invention is not limited to one-box cars, but can be similarly applied to general passenger cars. Furthermore, the retractor 7 and one end of the flexible wire 10 may not be fastened together, but may be fixed separately.

(Effects of the invention) As is clear from the above, the invention has the following effects:
Even if the attachment part to the vehicle body that handles the strong tensile force that acts on the seatbelt in the event of a collision is located far away from the rear of the seat (seat bag), the seatbelt can be easily pulled close to the seatbelt. This eliminates the hassle of wearing a seatbelt.

Further, since it is only necessary to newly attach only the flexible wire portion, that is, the existing seat belt device can be used as is without major design changes, so it can be easily implemented.

Furthermore, since a flexible wire is used, it is easy to wear, and situations such as unreasonable twisting force are prevented.
