DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a reclining mechanism between a seat cushion and a seat back on a side of a seat frame, and a connector for a child seat is inserted and engaged from a slit provided on a seat surface near a rear portion of the seat cushion. The present invention relates to an improvement in a reclining seat for a child seat equipped with a stopper which is provided on the rear side of a seat cushion frame.

[0002]

2. Description of the Related Art In general, a reclining seat provided with a reclining mechanism between a seat cushion and a seat back on a side portion of a seat frame is mounted as a rear seat of a wagon vehicle or the like. As shown in FIG. 6, a pair of left and right slits 3 and 3 for inserting the connector 2 of the child seat 1 is provided on the seat surface near the rear of the seat cushion 4, and the child seat 1 is mounted on the seat surface portion.

[0003] In the child seat equipped seat,
A pair of left and right stoppers are provided on the rear side of the seat cushion frame so that the connector of the child seat is inserted into and engaged with a slit provided on a seat surface near the rear of the seat cushion. The stopper is formed by bending a metal shaft into a predetermined axial shape, and is fixed to the seat cushion frame by welding and fixing the base of the shaft to the rear portion of the seat cushion frame.

[0004] In the child seat equipped seat,
When an impact force is applied, the stopper must be rigid enough to withstand the impact load so that the catch is not pulled forward and bent. However, there is a concern that simply bending the metal shaft into a predetermined axial shape and fixing the shaft root to the rear portion of the seat cushion frame will provide rigidity that can withstand an impact load.

Further, in order to provide the stopper, if the slit for inserting the connector of the child seat is set near the seat side end of the main seat cushion according to the specification of the main seat, the reclining mechanism is required. The clasp on the side of the frame to be provided requires a contrivance in the mounting structure because the reclining mechanism is in the way.

[0006]

SUMMARY OF THE INVENTION The present invention provides a reclining mechanism extending between a seat cushion and a seat back on a side of a seat frame, wherein a slit for inserting a connector of a child seat is provided on a side of a seat surface of the seat cushion. It is an object of the present invention to provide a reclining seat for a child seat equipped with a structure in which a stopper can be provided even if it is set near the end and improved so that the stopper can have rigidity to withstand a tensile load.

[0007]

In a reclining seat for a child seat according to the present invention, a downwardly U-shaped frame receiving metal is mounted and fixed on a rear axis of a seat cushion frame, and a frame side having a reclining mechanism is provided. As a stopper of the portion, a laterally U-shaped stopper which is fitted and fixed behind the frame receiver is provided so as to protrude to the upper side of the reclining mechanism.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 to 5, a preferred embodiment of the present invention is similar to that shown in FIG. It is configured so that two sets of slits are provided on the seat surface near the rear of the seat cushion.

The seat cushion is assembled on the basis of a seat cushion frame 10 as shown in FIG. The seat cushion frame 10 is formed mainly by bending a metal pipe material into a substantially quadrangular frame shape.

On the rear axis of the seat cushion frame 10, stoppers 11a and 11b near the center, which are formed by bending a metal shaft into a predetermined axial shape, and stoppers 12a and 12b near both sides, connect a child seat connector. It is provided as an anchor. Each stopper 11a, 1
1b, 12a, and 12b are formed by bending a metal shaft having a diameter of about 10 mm into a predetermined axial shape.

Among them, the stoppers 11a, 11 near the center
As shown in FIG. 2B, a metal shaft is bent in a substantially downward U-shape as shown in FIG. 2, and is attached by welding and fixing the lower ends of the shafts of both legs to the rear side surface of the seat cushion frame 10.

In addition, the stoppers 11a and 11b
Both legs are fixed by welding to the backs of the frame receivers 13a and 13b, and the upper shaft side for latching the connector of the child seat is protruded from the frame receivers 13a and 13b so that the frame receivers 13a and 13b (see FIG. 1). Is fixed to

As shown in FIG. 3, the stoppers 12a and 12b closer to both sides are formed by bending into a laterally U-shaped axial line shape. These stoppers 12a, 12b are applied by welding both legs to the backs of the frame receivers 14a, 14b, and the upper shaft side portions are laterally arranged from the frame receivers 14a, 14b as axis portions for latching the connector of the child seat. It is attached to project outward.

Each of the catches 11a, 11b, 12a,
Frame receivers 13a, 13b, 1 for applying and fixing 12b
Reference numerals 4a and 14b denote rigid metal fittings formed by press-forming a flat steel material in a downward U-shape, and are attached by welding and fixing both legs to the axis of the seat cushion frame 10.

In the child seat equipped seat having the base of the seat cushion frame constructed as described above, the catches 11a, 11b, 12a, 12b are applied to and fixed to the frame receiving members 13a, 13b, 14a, 14b. Since the stiffness can withstand, even if an impact force is applied, the stoppers 11a, 11b, 12
The movement amount of the child seat can be suppressed by reliably preventing the a and 12b from falling forward.

Since the stoppers 12a and 12b are provided so as to protrude above the reclining mechanisms 15a and 15b (see FIG. 1), a slit for inserting a connector of the child seat is provided near the seat cushion side end of the seat cushion. , The reclining mechanisms 15a, 15
b is attached so as not to interfere.

The stoppers 11a, 11b, 12a, 12
4, the bearing metal 16 having a substantially U-shape facing downward is raised to support the front side of the seat cushion from below as shown in FIG.
The seat cushion frame 10 may be attached and fixed on the front axis by welding and fixing on the axis. The bearing 16 can also be formed of a metal shaft having a diameter of about 10 mm.

In the illustrated embodiment, the bearing metal 16 is fixed to a corner (see FIG. 1) of the seat cushion frame 10 extending from the front axis to the side axis. In addition, the seat cushion frame 10 is also provided on the front central axis of the seat cushion frame 10 as needed to stably support the front side of the child seat.

When the bearing metal 16 is provided, the front side of the child seat can be stably supported, and even if an impact force is applied, as shown in FIG.
Due to the load, the cushion pad is flexed and deformed, so that the seat cushion 4 is prevented from sinking greatly, and the movement amount of the child seat 1 can be suppressed.

[0020]

As described above, according to the reclining seat for child seat equipment according to the present invention, the downwardly U-shaped frame receiving metal is fixedly mounted on the rear axis of the seat cushion frame, and the reclining mechanism is provided. By providing a laterally U-shaped stopper that is fitted and fixed behind the frame receiver as a stopper on the side of the frame, and protruding from the upper side of the reclining mechanism, a slit for inserting the connector of the child seat is provided on the seat surface of the seat cushion. Even if it is set near the side end, the reclining mechanism can be attached without obstruction.

In addition, by fixing the catch to the back of the frame receiving metal which is mounted and fixed on the rear axis of the seat cushion frame, it provides rigidity that can withstand a tensile load. In addition, it is possible to reliably prevent the stopper from falling forward, thereby suppressing the amount of movement of the child seat.
