Description

Buckle Support Structure of Automobile Seat Belt

The present invention relates to a structure in which a buckle (buckle) of a vehicle seat belt is supported on a vehicle body, and thus, a predetermined width can be stretched by improving a support structure of a lower end of a buckle, thereby improving convenience in use and improving wearing comfort.

In general, the interior of the vehicle, as shown in Figure 1 and 2, the cushion 10 for seating the occupant is installed on the top of the floor panel 30 to form a floor, the rear end of the cushion 10 The backrest 20 is rotatably connected, and the buckle 40 is formed in one side of the cushion 10, the receiving fastening portion is fixed, the other side of the cushion 10 by the insertion plate to the storage fastening of the buckle 40 The belt 60 to be attached to and detached from the part is provided to be pulled out so that the length is variable.

In the conventional vehicle configured as described above, when the occupant seated on the cushion 10 and the backrest 20 pulls the belt 60 to fasten the insertion plate to the buckle 40, the belt 60 is elastically attached to a part of the body. It is in close contact, so that the belt 60 to suppress the crew is to be bounced toward the front of the vehicle due to an accident, such as a collision while driving, thereby protecting the crew.

Here, the belt 60 has one end wound on a winding machine which is elastically drawn out and wound, the other end is supported by the vehicle body on the side of the upper end side of the backrest 20, and the middle part is buckle by the insertion plate which is supported to be movable. It is attached to and detached by 40.

When the belt 60 is pulled together with the insertion plate, the portion wound on the winder is drawn out elastically, and when the pulling force is removed, the belt 60 is wound again by the elastic force of the winder, and the one end and the other end supported on the vehicle body side. And the insertion plate is inserted into the buckle 40 is supported to form a triangular support point to support the lower abdomen and the chest of the crew.

On the other hand, the buckle 40 is formed in the upper end of the receiving fastening portion and the lower end of the elastic deformation is possible the upper end of the wire 42 is coupled, the lower end of the wire 42 is fixed to the floor panel 30 by the fixing bolt 41 It is intended to be fixed.

The buckle 40 is inserted into the inserting portion of the belt 60 to support the intermediate portion of the belt 60, the wire 42 when the load acts on the belt 60 due to the collision of the vehicle, etc. And to be dispersed in the floor panel 30 through the fixing bolt (41).

The seat belt installation structure of the conventional vehicle, when the crew moves forward, one end of the belt is slipped by the winder, at which time the top of the crew is slipped by one belt, so that the other side of the top is wound and worn There was an uncomfortable problem.

The present invention improves the support structure of the buckle to allow the insertion plate of the belt detachable, so that the buckle support can also be stretched by a predetermined width when the occupant wearing the seat belt moves forward, so that the convenience and comfort of use is improved. There is this.

First, the present invention also has a cushion is installed on the top of the floor panel to form a floor seating, the back end is pivotally connected to the rear end of the cushion, the buckle is formed on one side of the cushion buckle is formed It is fixed, and the other side of the cushion is installed to be pulled out so that the belt is detachable to the storage fastening portion of the buckle by the insertion plate is variable.

3 and 4, the wire 42 of the buckle 40 mounted to the floor panel 30 moves inside the cylinder 50 to which the return spring 53 is mounted. Possibly supported by its technical construction.

According to the present invention configured as described above, when a tension load is applied to the buckle 40, the wire 42 presses the return spring 53 inside the cylinder 50 and is drawn outward, and when the tension load is removed, the return spring is removed. The elastic force of the 53 is accommodated into the cylinder 50, so that the buckle 40 and the wire 42 are stretched as the crew moves.

Here, the cylinder 50 has a coil type return spring 53 mounted therein, a slider 51 supported by the return spring 53 is movably mounted therein, and a roller 52 rotates at the front end thereof. It is mounted so that the middle portion of the wire 42 of the buckle 40 is in close contact with the outer circumferential surface of the roller 52, the end of the wire 42 is penetrated into the cylinder 50 to be integrally moved to the slider 51 do. Further, a valve 54 is formed at the upper end of the cylinder 50, and an air hole is formed at the rear end.

The cylinder 50 presses the return spring 53 when the tension force is applied to the wire 42 by the buckle 40 and the slider 51 is moved toward the distal end. When the tension force is removed, the cylinder of the return spring 53 is removed. The slider 51 moves with the wire 42 toward the rear end by the force. On the other hand, when the slider 51 is moved toward the front end, air is sucked into the rear air hole, and at the same time, the valve 54 is opened to exhaust the air inside the cylinder 50, and the slider 51 moves toward the rear end of the rear end of the ear canal. The air in the cylinder 50 is discharged to the air hole and the air is sucked through the valve 54.

On the other hand, the valve 54 of the cylinder 50, as shown in Figure 4, the valve operating space is formed in communication with the operating space of the cylinder, the air hole through the outside is formed in the upper end of the valve operating space is formed A separate air passage 55 is formed at one side of the valve operating space to communicate with the inside of the cylinder working space, and a coil spring 56 is mounted inside the valve operating space, and a lower end of the coil spring 56 is provided. The piston 57 being supported is moveably mounted, and a valve formed integrally movable at the upper end side of the piston 57 is mounted to be openable and openable in the upper air hole.

In this case, the valve 54 of the cylinder is inhaled or exhausted through a separate air passage 55 and an upper air hole in accordance with the forward and backward movement of the slider 51 in a normal case in which the crew moves for driving operation. When a certain impact load is applied to the buckle 40 due to an accident or the like, the piston 57 is operated by the cross-sectional area difference (F = PA) between the slider 51 and the piston 57 according to Pascal's principle. Thus, the valve closes the air hole at the top so that the movement of the slider 51 is suppressed, so that the stretching of the wire 42 and the buckle 40 is prevented.

The present invention constructed and operated in this way, the wire of the buckle to allow the insertion plate of the seat belt detachable is elastically supported, the expansion and contraction is suppressed when the impact load is applied, the crew wearing the seat belt is moving forward The buckle support also allows a predetermined width to be stretched, and in case of emergency, the stretch is prevented, thereby improving convenience and wearing comfort.
