Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a seat belt buckle mounting device in which a seat belt buckle can be stored in a seat buck.

[Conventional technology]

Conventionally, as a seat belt buckle attachment device, there has been proposed a structure in which the buckle is rotatable in the vehicle front-rear direction and moves from a state of being stored in the seat buck to a side projecting position of an occupant during use. (Actual public Sho 55-49080
Issue). Further, it has been proposed that a stopper is formed on the bag and is positioned in an elongated hole formed in a bracket on the vehicle body side to regulate the swinging angle of the bag (Japanese Utility Model Laid-Open No. 62-38753).

However, in these seatbelt buckle attachment devices, when the buckle is in the projecting position, when the passenger moves in the vehicle compartment, the bug hits the occupant and the movement of the occupant is hindered, and the latter In the above, there is a possibility that the positioning device at the swing angle may be deformed when an external force is forced on the bag from above.

[Problems to be solved by the device]

In consideration of the above facts, the present invention prevents the movement of the occupant from being hindered when the occupant moves in the vehicle compartment while the occupant is in the projecting position, and a device for positioning the swing angle of the occupant is provided. It is an object of the present invention to provide a seat belt buckle attachment device capable of preventing deformation of the seat belt.

[Means for Solving the Problems]

The present invention is directed to a vehicle supporting member for supporting a vehicle, an extension plate on which the vehicle supporting member is swingably supported, and the vehicle provided between the extension plate and the vehicle supporting member for supporting the vehicle on the passenger side. And a seat rocking angle adjusting means for selectively arranging the seat rocking position and the seat back storing position, and the bag supporting member is movable from the projecting position to a retracting position below the seat cushion. And an elastic body interposed between the anchor plate and the extension plate for urging the bag from the retracted position toward the projected position.

[Action]

In the present invention having the above configuration, when an occupant operates the bag,
The bag swing angle adjusting means selectively arranges the bag at two positions, a protruding position and a storage position. Therefore, when the occupant is not in the vehicle, the bag is stored in the seat back, and the occupant can easily get on and off and move inside the vehicle.
Further, the occupant puts on the webbing after sitting down with the bag as the protruding position. Also, if the occupant moves by a switch operation or the like and hits the bag while the vehicle is in the projecting position, the extension plate moves against the elastic body and the vehicle supporting member moves from the projecting position to the retracted position. Since it moves to, there is little discomfort and the swinging angle adjusting means of the bag does not deform.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS.

As shown in FIGS. 1 and 2, the bag attachment device 10
An anchor plate 14 is arranged at an end portion of the vehicle floor 12 side (hereinafter, referred to as a lower side). The anchor plate 14 is arranged below the seat back 16. An extension plate 22 is pivotally supported by a rivet 24 on an outer piece 14A and an inner piece 14B of the anchor plate 14 which are parallel to each other. The rear upper end portion of the outer piece 14A and the rear upper end portion of the inner piece 14B are connected by a connecting portion 14C, and the lower end portions of the outer piece 14A and the inner piece 14B are bent at right angles to be overlapped with each other, and with a washer. It is integrally fixed to the floor 12 by bolts 20.

A rubber bush 2 is attached to the outer periphery of the rivet 24 between the extension plate 22 and the inner piece 14B of the anchor plate 14.
6 is inserted, and a torsion coil spring 28 is wound around the outer circumference of the rubber bush 26.

One end of the torsion coil spring 28 is hooked on the inner piece 14B of the anchor plate 14, and the other end is hooked on the extension plate 22.
In addition, the extension plate 22 has a protrusion 22 on a part thereof.
A is provided so as to contact the upper end of the connecting portion 14C of the anchor plate 14.

Therefore, the extension plate 22 is moved by the urging force of the torsion coil spring 28 in the torsional direction to cause the rivet 24 to move.
Rotate backward (in the direction of arrow A in Fig. 1) about
Is in contact with the rear edge portion 14C of the anchor plate 14, but rotates forward (in the direction of arrow F) against the urging force of the torsion coil spring 28, and can move downwardly of the seat cushion 15. Has become.

Further, as shown in FIG. 2, the extension plate 22 includes a torsion coil spring 28 and a rubber bush 26.
The urging force in the axial direction of the rivet 24 pushes the rivet 24 in the vehicle outer direction (direction of arrow G in FIG. 2) along the axial direction, and the extension plate 22 is anchored to the anchor plate
Is in contact with the outer piece 14A. For this reason,
The extension plate 22 is a torsion coil spring.
The extension plate 22 can be displaced in the vehicle width direction by deforming 28 and the rubber push-up 26. Further, the rubber bush 26 holds the torsion coil spring 28 so as not to be displaced in the radial direction, and the end face thereof is pressed against the extension plate 22 by surface contact, so that the extension plate 22 is always in the vehicle width direction. Tries not to incline carelessly. An intermediate portion of the extension plate 22 is wrapped with a cover 23 so that an occupant does not touch the operating portion.

At the other end of the extension plate 22, the intermediate portion of the bag supporting member 30 is pivotally supported by the rivet 34, and the bush 32 is inserted into the rivet 34. An upper portion of the bag supporting member 30 is curved toward the front of the vehicle, and a bag 36 is fixed to an upper end portion thereof.

At the middle of the extension plate 22, a rivet 34
An elongated hole 22C is formed as a part of the vehicle swing angle adjusting means concentrically with the axis of the vehicle, and the rivet 40 fixed to the lower end of the vehicle supporting member 30 is inserted into the elongated hole 22C. Has been done. The bush 38 is inserted into the rivet 40. A rivet 42 is fixed by caulking near the midpoint of the elongated hole 2C of the extension plate 22,
One end of a click spring 44 as a part of the bag swing angle adjusting means is wound. The other end of the click spring 44 is wound around the rivet 40, and receives a biasing force in a direction in which the rivet 40 and the rivet 42 separate from each other.

Therefore, the rivet 40 is stopped by the biasing force of the click spring 44 at a position where the rivet 40 selectively abuts either one of both ends of the slot 22C with the longitudinal midpoint of the slot 22C as a boundary point. It has become. That is, when the rivet 40 moves forward past the intermediate boundary point of the slot 22C, the bag 36 and the bag supporting member 30 are moved to the rivet 40.
Is rotated to the rear of the vehicle until it hits the front end of the slot 22C, and becomes the position B (retracted position) 1B on the side of the seat back 16, and the rivet 40 moves rearward past the intermediate boundary point of the slot 22C. Then, the vehicle 36 and the vehicle support member 30 are rotated forward of the vehicle until the rivet 40 hits the rear end of the elongated hole 22C, and are rotated 35 ° forward (in the direction of arrow D) from the retracted position B to the position C (projected position). ).

In this case, when the bag 36 moves from the retracted position B to the projecting position C, the torsion coil spring 28 does not bend, and the click spring 44 bends so that the bag 36 moves in the direction of arrow D. The biasing force of the spring 28 is adjusted to be larger than the biasing force of the click spring 44. However, when the bag 36 is further pressed from the projecting position C toward the seat cushion 15, the buckle 36 bends the torsion coil spring 28 to enter below the seat cushion 15 and reach the retracted position.

The bag support member 30 is covered with a cover 46.

Next, the operation of this embodiment will be described.

Before the occupant is seated, the bag 36 is in the storage position B, and the occupant can easily get on and off. When an occupant sits on the seat cushion 15 and moves the bag 36 from the storage position B toward the projecting position C, the bag supporting member 30 rotates around the rivet 34 in the direction of arrow D. The bag support member 30 has an arrow D.
Is rotated in the direction, and the rivet 40 is clip spring.
When passing through the intermediate boundary point along the long hole 22C against the urging force of the 44, the urging force of the clip spring 44 is reversed and the bag supporting member 30 is urged in the direction of the arrow E, so that the backside of the long hole 22C is urged. It reaches the end and stops. This allows the backpack 36
The bag support member 30 is at the protruding position C.

Next, when the occupant pulls out the webbing and inserts the tongue plate into the bag, the occupant is in a restrained state. Also,
If the occupant hits the bag 36 when the occupant moves in the vehicle compartment by a switch operation or the like with the projecting position C at the protruding position C, the bag 36 and the bag supporting member 30 are further rotated in the direction of arrow D. At this time, the bag support member 30
Is unrotatable in the direction of arrow D, the bag support member 30 rotates in the direction of arrow F together with the extension plate 22 in the direction of arrow F against the biasing force of the torsion coil spring 28 around the rivet 24. Since the occupant is moved to the retreat position below the seat 15, the occupant is not hindered from moving and the bag swing angle adjusting means is not deformed. Further, when the occupant is separated from the bag 36, the extension plate 22 is rotated about the rivet 24 by the urging force of the torsion coil spring 28 in the direction of the arrow A.
The projection 22A is rotated in the direction
4C is contacted, and the bag 36 and the bag support member 30 return to the projecting position C.

When the occupant contacts the vehicle 36 and the vehicle 36 and the vehicle supporting member 30 are pressed in the vehicle width direction, the extension plate 22 is displaced in the vehicle width direction due to the deformation of the torsion coil spring 28 and the rubber bush 26. To do.

[Effect of device]

Since the present invention has the above-mentioned configuration, when the occupant moves in the vehicle interior with the bag in the protruding position, the movement of the occupant is not hindered and the positioning device for the swinging angle of the bag is modified. It has an excellent effect that it can be prevented.
