Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the buckle support device 10 of the present embodiment has a webbing 12 for restraining a passenger on a seat 1.
4 to protect the seated occupant 16.

One end of this webbing 12 is locked to an anchor plate 20 fixed to a side wall 18 of the vehicle body, and the middle portion is wound up into a webbing take-up device 28 through a tongue plate 24 and a through ring 26. This winding device 28 is attached to the side wall 18 of the vehicle body and winds up the webbing 12 with a biasing force, but has a built-in inertia lock mechanism that stops unwinding the webbing 12 in case of a vehicle emergency.

The through ring 26 is attached to the upper part of the side wall 18 of the vehicle body so that the webbing 12 can be folded back smoothly. Further, the elongated hole 30 provided in the tongue plate 24 also allows the middle portion of the webbing 12 to be freely inserted therethrough.

As shown in FIGS. 2 and 3, the buckle supporting device 10 is constructed by inserting a thin webbing 38, which is a tensile material, into a long hole 36 provided in a flange 34 of a buckle 32, folding it back, and then sewing it. The other end of the narrow webbing 38 is folded back at the elongated hole 42 of the anchor plate 40 and then sewn, thereby connecting the buckle 32 and the anchor plate 40. The narrow webbing 38 has a large tensile strength like the occupant restraint webbing 12, and is designed to reliably support the external force applied to the buckle 32 in the event of a vehicle emergency.

The tongue plate 24 can be engaged with the buckle 32, and after the passenger 16 is seated on the seat 14, the tongue plate 24 and the buckle 32 are engaged with each other, so that the webbing 12 can be attached. Furthermore, by pressing the release button 44 of the buckle 32, the tongue plate 24 can be easily disengaged and the webbing can be released (the internal structure of the buckle 32 is not shown).

A mounting bolt 46 passes through the anchor plate 40 , and by screwing the mounting bolt 46 into a tunnel portion 48 provided approximately at the center of the vehicle body, the anchor plate 40 is securely attached to the vehicle body, and the narrow webbing 38 It is designed to support the tension of

This anchor plate 40 is the anchor cover 5
It is inserted into the anchor plate recess 52 of No. 0. As shown in FIG. 4, the anchor cover 50 has a thick plate shape and is made of synthetic resin, and the anchor plate recess 52 has a shape into which the semicircular portion 40A of the anchor plate 40 is inserted. A pair of protrusions 54 protrude from near the entrance of the anchor plate recess 52 in a direction that reduces the width of the anchor plate 40.
It is adapted to be inserted into the recess 56 of the.

Therefore, when inserting the semicircular portion 40A into the anchor plate recess 52, the anchor plate 40 is inserted by bending the anchor cover 50 due to its elasticity and pushing the pair of protrusions 54 apart from each other. After insertion, the protrusion 54 of the anchor cover enters into the recess 56 of the anchor plate 40 to prevent the anchor plate 40 from falling off. Therefore, the protrusion 54 and the recess 56 constitute a holding means, and after inserting the anchor plate 40 into the anchor cover 50, the anchor plate 40 is prevented from falling off carelessly and the assembly operation is not hindered. It's summery. Note that the holding means can also be constructed by partially increasing the width of the anchor plate 40 to provide a protrusion, and forming a recess in the anchor cover 50 into which the protrusion enters.

The anchor cover 50 is provided with bolt insertion holes 58 coaxially with the mounting bolts 46 of the anchor plate 40 to be assembled.
A mounting bolt 46 can be passed through the anchor plate 40 inserted into the anchor plate 40. A spacer 60 is inserted from the distal end of the inserted mounting bolt 46 as shown in FIG.

Anchor cover 50 has anchor plate recess 5
A pair of protrusions 62 protruding along the anchor plate 40 are provided in parallel to each other near the inlet portion of the anchor plate 40 . These protrusions 62 are attached to the narrow webbing 3
It is inserted into one end of the tube 64 covering the tube 8 and forms a uniform surface with no irregularities together with the outer periphery of the tube 64. The other end of this tube 64 is
As shown in the figure, it is inserted into a cylindrical portion 66 provided at the end of the buckle 32.

The tube 64 is a cylindrical body having a rectangular cross section as shown in FIG. 5, and is made of synthetic resin by extrusion molding. A thick wall portion 6 is provided at the corner of this tube 64.
8 is provided to integrally encapsulate the mild steel wire rod 70. This mild steel wire rod 70 is arranged in the longitudinal direction of the tube 64 and has the role of maintaining the shape of the tube 64. Therefore, the crew member
When the tube 64 is deformed in order to arrange the tube 2 at an arbitrary position, this deformed state can be maintained.

This embodiment configured in this way has a tube 64.
Since the tube is cylindrical, it is only necessary to cut the length of the tube 64 according to the specific car model and assemble it, and the same tube can be used for all car models. There is no need to make many copies each time. Further, the length of the narrow webbing 38 can be easily changed by cutting the longitudinal dimension to an appropriate length.

In the buckle support device 10 of this embodiment manufactured in this manner, when the occupant 16 sits on the seat 14 and engages the tongue plate 24 with the buckle 32, the webbing 12 becomes a three-point seat belt and is attached to the occupant. It will be installed.

In this case, since one end of the tube 64 is inserted into the protrusion 62 of the anchor cover 50, the tube 64 is securely erected from the anchor cover 50, which is fixed to the vehicle body with the mounting bolt 46, and the buckle 32 is placed near the waist of the occupant. This allows the crew to perform the buckle-up operation extremely easily. Furthermore, if it becomes necessary to change the arrangement of the buckle 32 due to the physical difference between the occupants or the adjustment of the seat 14 in the longitudinal direction of the vehicle, this can be easily done by deforming the tube 62.

Further, in the event of a vehicle emergency, a large tension is generated in the webbing 12, but this tension is reliably supported to the vehicle body via the buckle 32, the narrow webbing 38, the anchor plate 40, and the mounting bolt 46, so that the safety of the occupants can be ensured.

Next, FIGS. 6 to 8 show other embodiments in which a mild steel wire rod 70 is enclosed within the tube 64. 6th
In the figure, thick portions 68 are shown at both ends of the tube 64 in the width direction.
In FIG. 7, thick portions 68 protrude outward from both ends of the tube 64 in the width direction, and the mild steel wire 70 is enclosed therein. In addition, in the tube 64 shown in FIG. 8, a mild steel wire 70 is enclosed near the center in the width direction of the tube 64, and the middle portion in the width direction of the tube 64 is made into a thick wall portion 68. The arrangement of the mild steel wire rod 70 is not limited to the above-mentioned modification example, but various modifications are possible.
