Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a seat belt device for an automobile.

(Prior Art) Generally, a seat belt device including a shoulder portion is installed in the front seat of a driver's seat or a passenger seat of an automobile to prevent the upper and lower body parts of an occupant from moving forward in the event of a collision.

A seat belt device with such a shoulder part is
Normally, one end (upper end) of the webbing of the shoulder section is inserted and locked into an intermediate hanger (sash guide plate) that is locked to the upper part of the center pillar, and the extended end is also connected to the vehicle body quarter trim below the center pillar. Seatbelt retractor (e.g. E L
R type) (see, for example, Japanese Utility Model Application No. 61-37055).

However, with such a configuration, in the case of a center pillarless vehicle such as a hard top vehicle, the intermediate hanger cannot be locked. Therefore, the intermediate hanger is sometimes locked using the roof sight rail on the side of the roof, but in that case, the seat belt is exposed as it is in the window area where there is no center pillar. This has the disadvantage that it becomes very unattractive.

For this reason, recently, a structure has been proposed in which the seat belt retractor and the intermediate hanger are both installed below the window section, so that the seat belt is completely invisible from the outside. (See, for example, Japanese Utility Model Application Publication No. 165527/1983).

(Problems to be Solved by the Invention) However, when the seat belt retractor, a portion of the intermediate hanger, etc. are installed below the window portion as described above, the following problems occur.

In other words, in general, the vertical wall of the vehicle body below the window, especially the inside of the door panel, has various mechanisms such as a door lock device, and inevitably requires a certain amount of space for raising and lowering the window glass, which is a constraint due to space factors. is large. Therefore, if you try to install a box-shaped seatbelt retractor that has a size that corresponds to the maximum webbing retracted state, you will inevitably have to adopt a structure in which the door panel part bulges considerably inward into the passenger compartment. do not have. However, forming such a bulge in the door panel part
Not only does it look unsightly, it requires complicated processing steps, and it also becomes an obstacle when getting on and off, which is undesirable.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above problems, and is an automobile comprising a shoulder portion and a seat belt retractor on one end side of the webbing of the shoulder portion. In the seatbelt device, the seatbelt retractor is provided in an arm and a strut that is a part of the vertical wall of the vehicle interior.

(Function) According to the above means, the seatbelt retractor is installed in the armrest that is originally provided on the vertical wall of the vehicle body below the window so as to protrude into the interior of the vehicle, so that the seatbelt is attached to the window. Not only can the door panel be hidden from view, but there is no need to form a bulge specifically for the retractor on the door panel, and the appearance is improved.

(Example) FIGS. 1 to 3 show an automobile seat belt device according to an example of the present invention.

In FIGS. 1 and 2, reference numeral 1 designates a three-point seatbelt provided, for example, corresponding to a driver's seat S, respectively.

The above-mentioned seat bell) 1 has a wrap part 2 that extends between the left and right ends of the waist part of the driver's seat S and is locked, and a first and second intermediate guide member 3 A on one end side of the webbing W.
A shoulder portion 5 that is wound so as to be pulled out or retracted into a seat belt retractor 4 (described later) via 3 B, and the other end side of the webbing W is continuous with one end side of the wrap portion 2, and the wrap portion 2 A first hook interposed at one end continuous with the shoulder portion 5 is a metal fitting (sash guide plate) 6, and the first hook engages with the metal fitting 6 to connect the wrap portion 2 and the shoulder portion. 5 at one end of the driver's seat S, a second hook provided at the other end of the wrap section 2 is a metal fitting 8, and the second hook is a metal fitting 8. 8 at the other end of the seat.

As shown in detail in FIG.
It is incorporated into the armrest 11 formed in 0A as described below.

That is, in FIG. 2, numeral 13 is the rear door!
0 is the door outer panel, and I4 is the door inner panel. The door panel section 10A is constructed by integrally bonding the door outer panel 13 and the door inner panel 14, and the door window glass 15 is mounted on the upper part of the door panel section 10A. It is fitted so as to be slidable in the vertical direction via the weather strip 16.16.

A door trim (trim board) 17 for interior use is integrally joined to the interior side wall portion of the door inner panel 14, and a portion of the door trim 17 is attached to the substantially middle portion of the door trim 17. The above-mentioned armrest 11 is formed by bulging toward the room.

A predetermined space 19 is formed inside this armrest ll between it and the door inner panel 14, and the above-mentioned seat belt retractor 4 is housed in the space 19, and upper and lower parts formed around the periphery of the space 19 are provided. It is fastened and fixed to the door inner panel 14 by bolt members 21.21 using the flange portions 20.20.

Further, an opening 22 for extending the seat belt webbing W pulled out from the upper part of the seat belt retractor 4 is formed at a position above the seat belt retractor 4 at the upper edge of the door trim 17; The opening 22 is provided with the second intermediate guide member (lid member) 3B in which a slit 23 corresponding to the cross-sectional shape of the seat belt webbing W is formed. Then, the seat belt webbing W pulled out from the seat belt retractor 4 passes through the guide hole 24 of the first intermediate guide member 3A from the second intermediate guide member 3B and continues to the shoulder portion 5 described above. are doing.

The first intermediate guide member 3A has a cross-sectional structure in which a guide hole 24 is formed as shown in FIG. 3, for example, and is attached to the right shoulder portion of the backrest portion 25 of the driver's seat S.

Therefore, when the webbing W of the seat belt l is not in use, it is wound and stored in the seat belt retractor 4 inside the armrest 11, while the second hook on the tip side pulls the metal fitting 8. By pulling out the webbing W, first attach the metal fitting 8 to the second hook.
When the first hook 6 is engaged with the first buckle part 9 and the first buckle part 7, the webbing W
As shown in FIG. 1, they are stretched at three points to form the above-mentioned wrap portion 2 and shoulder portion 5.

In this state, the shoulder portion 5 extends in the vertical direction at the position of the backrest portion 25 of the driver's seat. Therefore, unlike the case where the shoulder belt is located close to the window glass portion, it is not very visible from the outside, and the appearance is further improved.

Moreover, since the seat belt retractor 4 is installed in the armrest 11, which is originally provided on the vertical wall of the vehicle body below the window so as to protrude inward into the vehicle interior, a bulge specifically for the retractor is provided in the door panel 10A. It is no longer necessary to form the parts, and the appearance is also improved.

Note that the first intermediate guide member 3A is attached to the backrest portion 25 of the driver seat (or passenger seat) S.
The webbing W itself is not limited to the endless cross-sectional structure as shown in FIG. 3 above, but also has a cross-sectional structure that can be opened and closed as shown in FIGS. 4 and 5 as other embodiments, and the webbing W itself can be removed. Of course, it is also possible to do so.
