Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention relates to a child seat that is used by being attached to a vehicle seat.

<Prior Art> As shown in Fig. 4, a child seat has conventionally been developed by pulling out a pair of webbing c from the backrest b and the shoulders of the child seat main body a, which is generally sized to fit an infant. A tongue e provided at the lower end of the auxiliary pad d is connected to a buckle g provided at the front of the seat f to connect in a Y-shape to restrain the crotch and both shoulders.

<<Problems to be solved by the invention>> However, in the child seat with the structure described above, the auxiliary pad d concentrates the load caused by the forward movement of the child restrained in the child seat due to the impact force at the time of a collision. Due to this, the tongue e and buckle g, which are the attachment parts h between the auxiliary pad d and the seating part f, were subjected to overload and were sometimes deformed or damaged.

For this reason, it is conceivable to improve the plate thickness and material in order to increase the strength of the mounting portion h, but doing so poses problems such as an increase in weight and an increase in price.

Therefore, an object of this invention is to provide a lightweight and inexpensive child seat that can increase the load capacity of the auxiliary pad attachment portion against impact force.

<Means for Solving the Problems> In order to achieve this purpose, the child seat of this invention has a buckle provided in a recessed step at the front of the seating section, which is attached to a hanging part of a roughly L-shaped buckle mounting bracket. At the same time, the horizontal part of this bracket is fixed to the upper surface of the concave step, and a space is provided between the back of the buckle and the wall of the concave step opposite to it to allow deformation of the bracket. The present invention is characterized in that when an impact force is applied to the buckle through the buckle, the hanging part of the buckle mounting bracket can be deformed until it comes into contact with the wall surface of the recessed step part.

<<Operation>> The impact force applied to the buckle through the tongue of the auxiliary pad during a collision is absorbed by bending the bracket hanging portion of the buckle.

<<Example>> Hereinafter, an example of this invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the child seat of this invention consists of a hollow bucket-type child seat main body 3 in which a backrest 1 and a seating portion 2 are integrally formed, and a pair of seats pulled out from the front surface of the backrest 1. The seat includes a webbing 4 and an auxiliary pad 5 which is connected to the tip of the webbing 4 and holds the infant on the seat 2.

The auxiliary pad 5 has a tongue 6 which is integrally fixed to the lower end of the auxiliary pad 5, and is inserted into a buckle 8 which is attached to a recessed step 7 at the front of the seating part 2 via a buckle attachment bracket 11. It is fixed to the child seat main body 3.

Further, one end of the webbing 4 is pulled out from a pair of slits 9 among a plurality of slits 9 provided vertically in the backrest 1, and is connected to the upper end of the auxiliary pad 5, and the other end is pulled out from a pair of slits 9 provided vertically in the backrest 1, and the other end is connected to the upper end of the auxiliary pad 5. Retractor 1 with emergency locking device provided on the bottom surface of the step 7
0, it is always biased in the winding direction.

The child seat main body 3 is made of a synthetic resin material, and the surface is covered with a skin 3a that is soft to the touch.
covered with.

Mounting bracket 1 with buckle 8 fixed together
1 is formed of a metal plate into a substantially L-shape, a buckle 8 is fixed to the hanging part 11a, and a horizontal part 11
b is fixed to the upper surface 7a of the recessed step portion 7.

A bolt hole is formed approximately in the center of this horizontal portion 11b, while bolt holes are also formed in the recessed step upper surface 7a of the seating portion 2 and the bracket 10a of the retractor 10, and bolts 13 are inserted into these bolt holes. The buckle 8 is fixed in the recessed step 7 by tightening and fixing them together with the nut 14.

Wall surface 7b facing the back surface of the buckle 8 of the recessed step portion 7
is formed diagonally downward and toward the rear, and has an angle θ between it and the hanging portion 11a of the buckle mounting bracket 11.
A space 15 is formed which spreads out downwardly. A cushioning material 16 having elasticity, such as rubber, is also adhered to this wall surface 7b.

As shown in FIG. 3, when a child seat configured in this manner receives an impact during a collision, even if the auxiliary pad 5 receives a concentrated load from the forward movement of the infant on the seating section 2, The load causes the hanging portion 11a of the buckle mounting bracket 11 to bend within the angle θ of the rear space 15, so that the impact is absorbed by the energy spent in this bending. Therefore, this shock absorption prevents the tongue 6 from coming off the buckle 8 and preventing the buckle 8 from being damaged. Further, in this embodiment, when the hanging portion 11a of the bracket 11 tries to bend by an angle of θ or more, the force is absorbed by the cushioning material 16 attached to the wall surface 7b of the recessed step.

<<Effects of the invention>> As explained above, in the child seat of this invention, when the impact force at the time of a collision is received by the auxiliary pad, the impact is absorbed by bending the bracket of the buckle, so it is easy to attach the auxiliary pad. In addition, the strength of the bracket can be designed in anticipation of energy absorption due to bending of the bracket, making it possible to realize a child seat that is cheaper, lighter, and more reliable than conventional ones.

Furthermore, this invention has the advantage that when an impact force is applied to the buckle through the tongue of the auxiliary pad, the buckle is attached to the horizontal part of the approximately L-shaped buckle mounting bracket.
The hanging part rotates and deforms along with the buckle to absorb the impact, and after the hanging part comes into contact with the wall of the recessed part, the deformation is stopped to prevent further elongation of the webbing and auxiliary pad. Therefore, the child can be effectively assisted, and special equipment such as a retractor is not required, and from this point of view as well, an inexpensive and lightweight child can be provided.
