Description

[Detailed Description of the Invention] The present invention relates to a seat belt for protecting an occupant in an automobile, and in particular to a seat belt of the type that is automatically attached and released in mechanical conjunction with the opening and closing of a door.

The upper end of the shoulder belt of this type of seat belt is
Because it is linked to the door, it is moored to the door sash, but in the event of a sudden deceleration such as a collision, the door sash may become deformed or damaged due to the large load applied to the seatbelt, and there is a risk that the seatbelt will lose its ability to restrain the occupant.

Therefore, it is known that the large load applied to the seatbelt is transferred to the vehicle body to reinforce the door sash and securely restrain the occupant.

This project also provides a mooring device for the end of the seat belt based on the above-mentioned concept, and when the door is closed, the seat belt mooring member of the door sash is caught on the latching member on the vehicle body side, which is subject to a heavy load. To provide a vehicle with a shoulder belt that can be worn by passengers, and to always stretch the shoulder belt diagonally from behind the seat so that it fits well with the shoulders of the occupant.

An embodiment of the present invention will be described below with reference to the drawings.
Reference numeral 1 denotes a vehicle body, 2 a door, and 3 a door sash. A bracket 4 protrudes from a vertical frame 31 of the door sash 3 toward the interior of the vehicle close to the wall surface of the vehicle body.

A shaft pin 5 is provided at the tip of the bracket 4, that is, at the end on the vehicle interior side, approximately parallel to the vertical frame 31, and the upper end of the shoulder belt 6 is attached to it, or a mooring member 7 such as a hanging ring through which the shoulder belt 6 is passed is attached. It is supported by the shaft pin 5 so as to be freely rotatable in the inward and outward directions. The mooring member 7 and the shaft pin 5
so that they can swing as one.

A hook 8 protrudes from the end of the vehicle body 1 toward a position facing the shaft pin 5 of the bracket 4 when the door 2 is closed.

The hook 8 is fixed to the inner surface of the vehicle body 1 with a bolt 9, and its tip is bent outward so as to hold the shaft pin 5. Further, an escape groove 10 into which the shoulder belt anchoring member 7 enters is formed approximately at the center of the bent portion.

The hook 8 is covered by a bracket 11 which hides its mounting bolt 9.

In Figure 3, the door 2 is about to close, and when the door 2 is completely closed, the shaft pin 5 supporting the mooring member 7 of the shoulder belt 6 is attached to the hook 8 on the vehicle body side, as shown in Figure 2. The shoulder belt 6 and waist belt 12 are automatically installed.

When a large load is applied to the seat belts 6 and 12 due to sudden deceleration, the load is transferred to the mooring member 7, shaft pin 5,
The load acts on the vertical frame 31 of the door sash via the bracket 4, but since the shaft pin 5 engages with the hook 8, the load is transmitted to the vehicle body 1 via the hook 8, and the door sash 31 is prevented from being deformed or damaged.

Therefore, the effect of restraining the occupant by the seat belt is reliable.

As described above, in this case, the load is transmitted from the seat belts 6 and 12 to the vehicle body 1 using the shaft pin 5 and the hook 8, which are substantially parallel to the door sash vertical frame 31 facing each other when the door is closed.
Since this is done by engaging the members 5 and 8, by making the shaft pin 5 longer and molding the hook 8 wider to match it, the engagement surface pressure between the two members 5 and 8 can be lowered. Even if the hook 8 is made of a thin plate, it is robust.

Therefore, the molding of the bracket 4, shaft pin 5, and hook 8 is easy.

In addition, in this case, the bracket 4 for mooring the upper end of the shoulder belt 6 is made to protrude from the door sash vertical frame 31 toward the interior of the vehicle near the wall surface of the vehicle interior, so that the shoulder belt 6 can be attached to the occupant's shoulder from diagonally behind the seat. It is installed deeply and is installed correctly regardless of the sitting height and shoulder width of the occupant.

Furthermore, the mooring part of the shoulder belt 6 can be rotated inward and outward around the shaft pin 5, so even if the occupant moves from side to side while the belt is attached, there is no risk of it coming off the shoulder, and there is no resistance to wearing it. Seat belts are available.

In the embodiment shown in FIGS. 1 to 3, the shoulder belt 6 is passed through the ring of the mooring member 7 and connected to an automatic winder (not shown) built into the door 2, but as shown in FIG. The upper end of the belt 6 may be fastened to a mooring member 7.

A torsion coil spring 1 is attached to the shaft pin 5 as shown in Figure 5.
3 can prevent the mooring member 7 from wobbling.

FIG. 6 shows a modification in which the mooring member 7 and the shaft pin 5' are integrally molded.
