DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment A child seat 1 according to a first embodiment of the present invention will be described below with reference to FIG.
0 will be described.

As shown in FIG. 1, the child seat 10 includes a base 12 and a vest 14 which is detachable from the base 12.

The base 12 is composed of a high-strength frame 16 composed of a pipe and functioning as a frame member, a cushion material (not shown) for covering the seat cushion portion 16A and the seat back portion 16B of the frame 16, and an upper end portion of the frame 16. And a headrest 18 to be mounted.

More specifically, a straight bar-shaped front cross bar 20 is stretched between both sides of the front end of the seat cushion portion 16A of the frame 16. At the center of the front crossbar 20, a buckle device 24 for a crotch belt is disposed via a belt 22.

A lap-side webbing 28A of a three-point seat belt device 26 mounted on a vehicle seat (not shown) is locked at a corner where the seat cushion portion 16A and the seat back portion 16B of the frame 16 intersect. A hook-shaped webbing locking portion 30 for causing the webbing to lock is attached. The seat belt device 26 is provided with a webbing 28 for restraining the occupant, an anchor plate 29 erected from the vehicle body floor to lock one end of the webbing 28, and a webbing provided near the lower end of the center pillar. A webbing take-up device for winding the other end of the webbing 28, a shoulder anchor disposed above the center pillar and through which an intermediate portion of the webbing 28 is inserted, and an upright standing on the opposite side to the anchor plate across the vehicle seat Buckle device 32
And a tongue plate 34 that is inserted into the intermediate portion of the webbing 28 and is engaged with the buckle device 32.

The seat back portion 16 of the frame 16
A lower buckle device 36 is provided near both lower ends of B, and an upper buckle device 38 is further provided near both upper ends of B. Also, the upper buckle device 3
A clamping device 40 for holding the webbing 28B on the shoulder side of the seat belt device 26
Are arranged.

The seat back portion 16 of the frame 16
A straight bar-shaped rear cross bar 42 is stretched between both side portions of the upper end of B. The upper ends of a pair of carry belts 44 are locked to the rear crossbar 42, and the lower ends of the carry belts 44 are connected to a lateral rear pipe 45 connecting the rear ends of the front crossbar 20. Locked.

On the other hand, the vest 14 is sized to be worn by a child occupant. A child restraint belt 46 for restraining a child occupant is attached to the vest 14 by sewing. This child restraint belt 4

The webbing 28B on the shoulder side is connected to one of the clamping devices 4.
0, and the webbing 28A on the lap side is locked by the left and right webbing locking portions 30. At this time, since the fixed state of the base 12 to the vehicle seat can be sufficiently checked visually, a stable fixed state of the base 12 can be easily obtained.

On the other hand, the occupant of the child wears the vest 14 and then sits on the base 12. Next, the lower tongue plate 48, the upper tongue plate 50, and the crotch belt tongue plate 52 are engaged with the lower buckle device 36, the upper buckle device 38, and the crotch belt buckle device 24, respectively. This allows
The vest 14 is connected to the base 12 and the child
4. Via the child restraint belt 46 and the connecting means (lower tongue plate 48, upper tongue plate 50, crotch belt tongue plate 52, lower buckle device 36, upper buckle device 38, crotch belt buckle device 24) It is stably restrained by the base 12 firmly fixed on the vehicle seat. As a result, the occupant restraint performance of the best-type child seat 10 can be improved.

In the present embodiment, since the pair of carry belts 44 are provided on the base 12 in advance, the tongue plate 34 is detached from the buckle device 32,
If the fixed state of the base 12 to the vehicle seat is released,
The child seat 10 can be used as a carry. Therefore, in this sense, the child seat 10 of the present embodiment is excellent in convenience.

Further, in the present embodiment, the seat cushion 16A and the seat back 16B constituting the frame 16 of the base 12 are made of pipe material, so that the weight of the base 12 can be reduced.

In addition, in the present embodiment, the buckle device 24 for the crotch belt is set at the center of the front end of the seat cushion portion 16A of the base 12, and the lower buckle devices 36 are provided at a total of four places on the left, right, top and bottom of the seat back portion 16B.
And the upper buckle device 38 is set, and the crotch belt 46C of the child restraint belt 46 is attached to the crotch belt tongue plate 52 and the waist restraint belt 46 correspondingly.
A, lower tongue plate 4 on chest restraint belt 46B
8. Since the upper tongue plate 50 is set, the child restraint belt 46 and the base 12 are restrained at at least one position in each of the seat cushion portion 16A and the seat back portion 16B.
Therefore, according to the present embodiment, the restraint performance of the child can be improved.

[Second Embodiment] Next, a child seat 60 according to a second embodiment of the present invention will be described with reference to FIG. Note that the same components as those in the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

As shown in FIG. 2, this embodiment is characterized in that a method of fixing the base 12 to a vehicle seat using a dedicated connector 62 and a tether belt 70 is employed. More specifically, a long connector 62 protrudes from both sides of the rear end of the seat cushion portion 16A of the base 12. An engagement groove 66 is formed at a distal end of the connector 62. When the engagement groove 66 is inserted into an engagement fitting (not shown) provided on the vehicle seat, the distal end of the connector 62 is moved to the vehicle seat. Are engaged with the engaging fittings.

A locking member 68 formed by bending a bar into a substantially U-shape is fixed to a middle portion of the base 12 in the longitudinal direction of the rear cross bar 42. One end of the tether belt 70 is locked to the locking member 68. The other end of the tether belt 70 is provided with an engagement fitting 72.
Are engaged, and the engaging fitting 72 is engaged with an engaged portion (not shown) provided on the vehicle seat. As described above, the base 54 is fixed to the vehicle seat at two points above and below.

The outer diameter of the distal end 82A of the connecting pin 82 is set slightly smaller than the inner diameter of the circular hole 84A of the engagement hole 84, so that the distal end 82A can be inserted through the circular hole 84A. The width dimension of the straight portion 84B of the engagement hole 84 is the tip portion 82.
Since the outer diameter is smaller than the outer diameter of A, when the distal end portion 82A is lowered to the lower end of the straight portion 84B, the connection state is established. In order to further increase the restraining force on the occupant of the child, the connection pins 82 and the connection fittings 86 may be set at two or more positions above and below the seat back portion 16B of the frame 16.

Since the basic concept of the child seat 80 according to the present embodiment is the same as that of the first embodiment described above, the occupant restraint performance of the best-type child seat 80 can be improved and the convenience is excellent. I have. In addition, the effect of reducing the weight of the base 12 and improving the restraint performance of the child based on the set number of the connecting means can be similarly obtained.

Further, in the present embodiment, a total of eight buckle devices and tongue plates can be omitted, so that the cost can be reduced even if the number of newly provided connecting pins 82 and connecting hardware 86 is increased. .

[Fourth Embodiment] Next, a child seat 90 according to a fourth embodiment of the present invention will be described with reference to FIG. Note that the same components as those in the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.
