Abstract

PURPOSE:To disperse tension acting upon a pillar in to a door frame by moving a connecting member disposed at the pillar interlockingly with a rotating seat belt inserting anchor plate pivotally fixed at the pillar so as to fit the connecting member into the connecting hole of the door frame. CONSTITUTION:When tension acts upon a seat belt 6, an anchor plate 4, a pin 14 and a lever 15 are respectively rotated clockwise. A connecting member 18 is thereby pushed at one end 18a thereof by the lever 15 so as to be moved to the left against a spring 20, and thereby the other end 18b is fitted into the connecting hole 19 of a door frame 7. That is, a rear pillar 3b and the door frame 7 are placed in the connected state through the connecting member 18. As a result, even if large tension is applied to the seat belt 6, the tension acting upon the rear pillar 3b is partially born by the door frame 7 through the connecting member 18. The rear pillar 3b is therefore prevented from being pulled inward to the front to be deformed.

Description

DETAILED DESCRIPTION OF THE INVENTION E-INDUSTRIAL APPLICATION FIELD The present invention relates to an automobile door frame holding device.

[Prior Art] Details of the upper anchor portion 2 of the automobile seat belt device 1 shown in FIG. 5 are shown in FIGS. 6 and 7.
3, the sea lion plate 4 is attached to the pin 5 on the inch panel 3a.
A seat belt 6 is movably inserted through the slit 4a of the sea lion plate 4.

In the seat belt device 1 described above, when tension is applied to the seat belt 6, it is desirable from the viewpoint of reducing the weight of the vehicle that the tension is shared not only by the rear villa 3 but also by the door frame 7.

However, when tension is applied to the seat belt 6, the rear villa 3 is pulled inward and forward as shown by arrow A in FIG. Remove the tension from the door frame 7
The only thing I can do is to have them share the burden.

Therefore, as shown in FIG. 7, in the past, the rear villa was fixed to the inch panel b of the rear villa 3, or the thickness of the inner panel 3a and the outer panel 3b was increased, so that even if tension was applied to the seat belt 6, the rear villa 3 to prevent it from coming off the door frame 7.

In the figure, 9 is a hack panel, 10 is a weather strip, and 11 is a window glass fitted into the door frame 7.

[Problems to be Solved by the Invention] However, in order to ensure the strength and rigidity of the rear villa 3, the reinforcing member 8 extends from the vicinity of the attachment portion of the anchor plate 4 of the inner panel 3a to the roof panel, resulting in a large size. Increasing the thickness of the outer panel 3b has the problem of increasing the weight of the vehicle.

In view of the above-mentioned circumstances, the present invention makes it possible to share the tension acting on the seat belt with the door frame without increasing the size of the reinforcing material or the thickness of the capillary, and also aims to reduce the weight of the vehicle. This was done for that purpose.

[Means for Solving the Problems] The present invention is capable of moving forward and backward in conjunction with the rotation of an anchor plate for inserting a seat belt that is pivotally connected to a pillar, and that when moving forward, the tip portion is inserted into a connecting hole provided in a door frame. A fittable connecting member is installed on the pillar.

[Function] The rotation of the anchor plate causes the connecting member to move forward, and its tip end is fitted into the connecting hole provided in the door frame. Therefore, the pillar and door frame are integrated, and the pillar will not deform even if tension is applied to the seat belt. Therefore, the tension acting on the seat belt is supported by the pillar and is also shared by the door frame.

[Implementation Example 1] Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show one embodiment of the present invention, and the parts designated by the same reference numerals as in FIGS. 5 to 7 represent the same parts.

A hollow cylindrical bearing 13 is installed in a hole 12 drilled in the inner panel 3a of the rear biller 3, a pin 14 is rotatably fitted into the bearing 13, and an anchor plate 4 is attached to one end of the bin 14.
and the lever 15 is fixed to the other end.

A hollow casing 16 is attached to the inner surface of the door frame 7 side of the outer panel 3b forming the rear biller 3, and a piston 17 is fitted into the casing 16 so as to be slidable in the axial direction of the casing 16. A connecting member 18 that penetrates the piston 17 and extends back and forth in the axial direction is fixed, the connecting member 18 is made to protrude outward from the front and rear of the casing 16, respectively, and one end 18a of the connecting member 18 is brought into contact with the lever 15, etc. When a large tension is not applied to the seat belt 6, the end portion 18b is attached to the door frame 7.
The connecting member 18 is inserted into the casing 16 so that it stops at a position away from the connecting hole 19 provided on the side of the piston 17.
A spring 20 that biases toward the lever 15 via the spring 20 is housed. The casing 16, the piston 17, the connecting member 18, and the spring 20 hold the door frame holding device 2.
form 1.

In addition, 3C is a hole bored in the outer panel 3b so that the other end 18b side of the connecting member 18 is inserted; 22 is a nut;
4 is a cap.

When no tension is applied to the seat belt 6, the anchor plate 4 and lever 15 are in the position shown in FIG.
The connecting member 18 of the door frame holding device 21 does not fit into the connecting hole 19 provided in the door frame 7, but is in a state where it is removed from the connecting hole 19.

When tension is applied to the seat belt 6, the anchor plate 4
Then, the pin 14 and the lever 15 are rotated clockwise in FIG.
Overcoming the drag force of 0, it moves to the left in Figure 1, and the other end 1
8b is fitted into a connecting hole 19 provided in the door frame 7. Therefore, the rear villa 3 and the door frame 7 are connected to the connecting member 1.
8, even if a large tension is applied to the seat belt 6, the rear villa 3 will not be pulled inward and forward and deformed as shown by arrow A in FIG. The tension acting on the door frame 7 is shared not only by the door frame 3 but also by the door frame 7.

Further, since there is no need to provide a large reinforcing plate or increase the plate thickness of the rear villa as in the conventional case to prevent deformation of the rear villa 3, the weight of the vehicle is reduced and the cost is also reduced.

When the tension on the seat belt 8 is released, the anchor plate 4 and the lever 15 return to their original positions due to their own weight and the weight of the seat belt 6, and the connecting member 18 is also returned to its original position due to the spring 20.

FIG. 4 shows another embodiment of the present invention, in which the pin 14 is
The striker 25 is fixed to the position detector 26 such as a limit switch by rotating the anchor plate 4.
When activated, a detection signal 27 is given to the control device 28,
A command signal 29 is given from the control device 28 to a solenoid 30, and a connecting member 31 that can be moved forward and backward by the solenoid 30 can be fitted into a connecting hole 19 provided in the door frame 7.

In this way, the sea lion plate 4 and the connecting member 31 can be electrically interlocked, rather than mechanically interlocked as in the previous embodiment.

In addition, in the embodiment of the present invention, the case where a contact type position detector is used to electrically detect the rotation of the anchor plate has been described, but it is also possible to use a non-contact type detector, and other matters may be explained. Of course, various changes can be made without departing from the gist of the invention.

[Effects of the Invention] As explained above, according to the automobile door frame holding device of the present invention, the tension acting on the seat belt can be shared with the door frame, and a large reinforcing member is not required. Furthermore, since there is no need to increase the thickness of the pillar, the vehicle weight can be reduced, the cost can be reduced, and various other excellent effects can be achieved.
