Description

[Detailed Description of the Invention] The present invention relates to a passive seat belt device for an automobile.

In order to improve passenger safety in automobiles, when a passenger gets in the vehicle, the seat belt automatically fits the passenger's body regardless of the passenger's will, and when the passenger opens the door and attempts to exit the vehicle, the seat belt automatically closes the seat belt. A so-called passive seat belt device has already been developed in which the belt is separated from the occupant's body, allowing the occupant to freely exit the vehicle.

As a seat belt, a so-called shoulder belt that is worn across the passenger from one shoulder to the other's waist is effective, but when such a shoulder belt is of the automatic fastening type as described above, In the past, one end of the seatbelt had to be attached to the sight rail on the upper side of the vehicle body, so conventionally a guide mechanism and its drive were used to guide the seatbelt back and forth along the sight rail as the door was opened and closed. Generally, complex mechanisms are required, and not only are they quite expensive as a whole, but there are also problems in terms of installation space for the various mechanisms.

The present invention provides a passive seatbelt device that does not require any conventional complicated mechanisms such as guide mechanisms and drive devices for automobiles with satsuri-less doors as described above, and also reduces the load applied to the seatbelt in the event of a vehicle collision, etc. The system is designed to provide reliable support and improve the safety of the occupants, and will be explained in detail below with reference to the accompanying drawings.

In FIG. 1, 1 is a seat belt, one end of which is attached to a vehicle body member (floor or a member fixed to the floor, etc.) at the rear lower part of the center side of the seat 9 via a retractor 2, and the other end is attached to the seat belt. 9 is coupled to a door pole 4 which is provided on the inch side of the rear window layer portion of the door 3 so as to protrude upward by a predetermined height.

The details of the four parts of the door pole are as shown in FIG.

That is, the door pole 4 is made of, for example, synthetic resin, and has an engaging member 5 made of, for example, metal fixed to the upper inward side thereof with a screw or the like, and the engaging member 5 is provided with a seat belt. The outer ends of the engagement member 5 are connected to each other, and the engagement member 5 is provided with an engagement hole 5a and an engagement portion 5b.

On the other hand, as shown in FIG. 3, a locking member 7 made of metal or the like is fixed to the vehicle body side such as the center pillar 6 facing the door pole 4 together with a cover 8 made of synthetic resin or the like that covers it. The locking member 7 is provided with a locking hole 7a and a locking portion 7b, and when the door 3 is closed, the locking portion 5b of the locking member 5 on the door pole 4 side locks the locking member 7 on the vehicle body side. Hole 7
a, and the locking portion 7 of the vehicle body side locking member 7
b is adapted to fit into and engage with the engagement hole 5a of the door pole side engagement member 5.

In the above structure, when the door 3 is closed, the door pole 4 is provided at the rear part of the window layer of the door 3 to protrude upward by a predetermined height, so that the upper part of the door pole 4 is located at the side of the shoulder of the seated occupant. Located at the rear, the seat belt 1 is automatically retracted by a retractor 2 and fitted across the occupant from one shoulder to the other waist, thereby restraining the occupant's body.

In this state, the retaining member 5 provided on the door pole 4 and the locking member 7 on the vehicle body side are tightly engaged with each other as shown in FIG. 3, so the impact load applied to the seat belt 1 is ,
These engaging members5. Center pillar 6 via locking member 7
The force of the seat belt 1 to hold the occupant in the event of a collision is extremely strong, and the door pole 4, door 3, etc. will not be damaged or deformed by the impact load.

When the door is opened when exiting the vehicle, as the door 3 rotates, the door pole 4 pulls out the seatbelt 1 from the retractor 2 and moves from the outside to the front, releasing the occupant's restraint and allowing the occupant to get on and off the vehicle freely. Become.

Also, when the passenger gets in the car and closes the door 3, the door pole 4
returns to its original state, and the seatbelt 1 is retracted by the retractor 2, resulting in the seatbelt fastening state.

As described above, according to the present invention, it is possible to automatically fasten and release the seat belt in an automobile with a lockless door with an extremely simple configuration, and when the seat belt is fastened, the seat belt connecting part on the door side and the center pillar The engaging members and locking members provided on both sides of the car body, such as the Therefore, the safety of the seat belt can be significantly improved, and the modified shape of the door can completely prevent damage.
