DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inner belt constituting a vehicle seat belt.

[0002]

2. Description of the Related Art A buckle-type seat belt (inner belt) used for a bench-type rear seat has the following structure. In the first structure, as shown in FIG. 6, the inner belt 80 is composed of a webbing 81 and a buckle 82 provided at one end thereof, the other end of the webbing 81 is fixed to a seat cushion support member, and the buckle 82 is attached to the seat cushion. The seat cushion 95 is pulled out from the through hole 95 to the front side of the seat cushion 95 and placed on the seat cushion. In the second structure, as shown in FIG. 7, the inner belt 90 is composed of a metal bracket 96 and a buckle 91 provided at one end thereof, and the other end of the metal bracket 96 is fixed to the seat cushion support member 97. Belt 9 for holding buckle 91 in through hole 951 of seat cushion 95
0 structure.

[0003]

However, the first and second inner belt structures have the following problems.
In the first structure, since the length of the webbing 81 of the inner belt 80 is a minimum length so as not to cause slack (slack), the buckle 82 provided at one end of the webbing 81 is connected to the through hole of the seat cushion. It is not easy to pull out to the front side of the seat cushion.

In the second structure, a bracket 96 provided with a buckle 91 at one end is erected on a seat cushion support member 97, and the seat cushion 95 is moved so that a through hole 951 of the seat cushion 95 coincides with the buckle 91. The assembling workability is good because it is assembled to the cushion support member 97, but when the body is laid down using the seat cushion 95 as a bed, the buckle 91 held by the bracket 96 hits the body and gives a foreign body feeling.

The present invention has been made in view of such a conventional problem, and does not give a rough foreign body feeling when a body is laid or sat on a seat cushion, and facilitates an assembling operation. It is intended to provide a simple inner belt structure.

[0006]

The present invention has an inner belt structure in which one end of a webbing is fixed to a support member of a seat cushion, and a buckle provided at the other end of the webbing is held by a holding member in a through hole formed in the seat cushion. And a vertically elastically deformable leg having a holding portion capable of holding the buckle, and an opening for projecting one end of the webbing laterally below the holding portion. The holding member has a buckle held by the holding portion, and one end of the webbing protruding from the opening of the leg portion is fixed to the support member of the seat cushion, so that the holding member is mounted on the seat cushion support member. An inner belt structure characterized in that it is configured to be positioned at a fixed position.

[0007] In addition to the holding member that holds one inner belt, there is a holding member that holds a plurality of inner belts at the same time. In this case, openings are formed on both sides of the leg from which the webbing of each inner belt projects. The webbing provided and projecting from the opening is fixed to the seat cushion support member on both sides of the holding member.

[0008]

In the inner belt according to the present invention, one end of the webbing protruding from the opening of the leg is fixed to the supporting member of the seat cushion in a state where the buckle is held in the holding portion of the holding member. Is positioned at a fixed position on the seat cushion support member. Further, since the legs can be elastically deformed in the vertical direction, when a pressing force acts on the buckle (or the holding portion) from above, the legs are elastically deformed and the buckle (and the holding portion) sink downward.

Therefore, it is not necessary to fix the holding member for holding the buckle in the through hole of the seat cushion to another component. In addition, when the body is laid on the seat cushion, the buckle (holding portion) similarly sinks with the sinking of the seat cushion, and it is less likely that the buckle (holding portion) hits the person's body and gives a foreign body feeling. . As described above, according to the present invention, it is possible to provide an inner belt structure which does not give a rough foreign body feeling even when the body is laid or sits on a seat cushion and which is easy to assemble. Can be.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An inner belt 10 of this embodiment has a webbing 11 fixed at one end to a support member 21 of a seat cushion as shown in FIG. 2, and a buckle 12 provided at the other end of the webbing 11 is shown in FIG. Is held by the holding member 25 in the through hole 31 formed in the seat cushion 30 as described above. The holding member 25 is, as shown in FIGS.
Holder 27 that is arranged above 6 and holds buckle 12
And a leg 26 located below the holding portion 27 and capable of being elastically deformed in the vertical direction.
1 can be independent.

The holding portion 27 of the holding member 25 is, as shown in FIG. The leg 26 has a substantially U-shape that opens upward, and upper ends on both sides thereof are connected to the holding portion 27 to form openings on both sides, and has an elastic portion 261 that curves inward near the connection. ing.

As shown in FIGS. 2 and 3, each of the inner belts 10 on the left and right seats of the bench seat is disposed at the center of the seat, and both buckles 12 have their lower ends extended and retracted by leg portions 26. It is held by the holding portion 27 while being in contact with the portion 261. The webbings 11 of the buckles 12 are pulled out from the openings 28 on both sides of the leg 26 so as to cross each other, and are fixed to the seat cushion support member 21 at a position close to the holding member 25. The holding member 25 is positioned at a predetermined position on the seat cushion support member 21 by fixing the webbing 11 as described above.

The seat cushion 30 is mounted on a bottom plate 35 (FIG. 3) as shown in FIG. That is, the trim 32 provided on the seat cushion 30 is engaged with the end of the bottom plate 35 and attached to the bottom plate 35. Further, as shown in FIG. 3, the support member 21 is fixed on the seat track 22. In FIG. 3, reference numeral 41 denotes a support frame for the rear seat.

After the inner belt 10 is erected on the support member 21, the seat cushion 30 mounted on the bottom plate 35 is mounted from above as shown in FIG. At this time, the inner belt 10 is
Is inserted into.

Since the holding member 25 is positioned at a predetermined position on the seat cushion support member 21 by fixing the webbing 11, no special operation is required for fixing the holding member 25 to another component, and the inner member is not required. Belt 11
After standing on the support member 21, the seat cushion is placed from above and assembled, so that the assembling work is easy. Further, since the leg 26 of the holding member 25 is vertically deformed, the inner belt 10 does not give a rough foreign body feeling when a person sits on the seat cushion 30 or lays down on the body.

Since the leg 26 is vertically expandable and contractible, the inner belt 10 can be easily assembled and fixed so that the webbing 11 is not loosened. As described above, according to the present embodiment, the inner belt can be easily stored in the seat without giving a rough foreign body feeling even when the body is laid or sitting on the seat cushion 30. Can be obtained.
