Description

Child Seat {CHILD SEAT}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a child seat, and relates to a child seat that is appropriately attached to a seat of a vehicle or the like so as to safely restrain the infant's body in the vehicle.

Background Art [0002] Heretofore, a child seat has been used to safely restrain the body of infants and children on board a vehicle. The child seat is determined by the standard of attachment to the seat according to the weight of the infant and the approximate age of the infant.

In the current standard (eg European Community standards), the child seat is attached to the car seat backwards for a weight of less than 13 kg (approximately 9 months for newborn infants) Kg), it is stipulated to be attached to the front. For this reason, in a child seat assumed to be used up to about four years old from a newborn child, various studies have been conducted so that the child seat can be stably attached to the seat of a vehicle in each attachment form.

For example, in a high-specification child seat, the child seat body is held on the relatively large base closely attached to the seat surface through the reclining mechanism. In this kind of child seat, the child seat body is fixed by changing the direction toward the seat of the vehicle and setting a suitable clining angle in accordance with the attachment form such as forward or rearward orientation using the reclining mechanism on the loaded base And it is possible to secure the appropriate restraint posture for infants and young children.

In the above-described child seat, the number of parts constituting the reclining mechanism is increased, and manufacturing costs are increased. In addition, the weight of the child seat is heavy due to the provision of the stable large base which is not affected by the attachment direction. In response thereto, various proposals have been made for stably attaching the child car seat as a supply to the seat of a vehicle.

The development point of the child car seat, which is an item of supply, is that the bottom of the child car seat is widely secured at each attachment position. As a child seat focused on this point, proposals have been made in which detachable block-shaped legs are rotated around the pivot axis along the attachment direction to change their positions (Patent Document 1).

In addition, it is possible to effectively prevent the child seat from rotating forward about the fixed point front end due to the frontal collision caused when the child is directed forward, and also to secure the bottom surface of the child seat even when the child- A child seat has also been proposed (Patent Document 2).

In the auxiliary sheet which changes the orientation of the two block-shaped legs disclosed in Patent Document 1 and corresponds to the change of the attachment position of the child seat, the end surface of the ribs 43 is located on the opposed surface 53 of the leg portion 51, 55 in order to have the flat portions 45, 46 and to have a reinforced structure. Since the leg portions 51 are independently provided at predetermined positions of the respective ribs 43, it is necessary to sufficiently reinforce the periphery of the two notches 47 at which the engaging projections 56 of the legs are fitted have.

In this way, in the child seat disclosed in Patent Document 1, it is necessary to secure sufficient rigidity to the ribs 43. As a result, the internal structure of the ribs 43 becomes complicated and the molding operation becomes difficult.

On the other hand, in the child seat disclosed in Patent Document 2, the support leg 6 has sufficient rigidity to improve the stability of the bottom front surface of the child seat. However, since the upper surface is exposed as a part of the product, A recessed portion for finishing the continuous smooth shape and for operating the center reclining mechanism, and the like are formed. In order to mount the child seat backward, as shown in Figs. 2 and 4, the upper face is inverted to be the bottom face, and together with the second contact portion 4b, forms the bottom face of the child seat. Therefore, in the state where this member is inverted, the contact surface on the seat can be ensured as shown in Fig. 2, but the flatness of the bottom surface of the child seat can not be ensured.

For this reason, stability in fixing the child sheet is lacking. In addition, there is a problem in use that the inverted member on the base overlaps the seat surface of the child seat so that it is difficult to burn and unload the child.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve the problems of the above-described conventional techniques, to make it possible to use the configuration of the arm-shaped ribs formed on the conventional child seat substantially and to secure a stable installation state A child seat is provided.

The bottom surface 12a of the base 12 has a substantially planar shape as shown in Fig. 1B, so that the child seat 1 can be stably mounted on the seat surface of the seat of the vehicle. The base stand 20 is pivotally supported on the inner surface plate 11b of the arm 11 at the intermediate portion 13 via a pivot pin 23. The base stand 20 is formed such that one side of the leg portion (which will be described later) forms a substantially flat surface with the bottom surface 12a of the base 12 at the lower end of the arm 11 , And functions as a part of the bottom surface of the child seat 1.

Here, the configuration of the base stand 20 will be described with reference to the respective figures of Fig. Fig. 2B is a side view of the base stand 20, Fig. 2C is a rear view of the base stand 20, Fig. 2D is a sectional view taken along line IId-IId of the base stand 20, Fig. The base stand 20 is composed of a stand body 21 and leg portions 22 formed integrally on both sides of the stand body 21. The stand main body 21 and the leg portions 22 are all made of a synthetic resin molded part integrally formed with outer plates 21a and 22a and lattice-shaped reinforcing ribs 21b and 22b formed therein. As the resin, polypropylene or the like is preferable. However, various resin materials can be used as long as the base stand satisfies the strength, durability, and the like, and is suitable for molding workability and cost.

As shown in Figs. 2A and 2B, the stand main body 21 is made of a flat box-shaped body having a substantially trapezoidal shape when viewed from the IIb-IIb line, and the width thereof is two And is substantially the same as that between the inner surface plate 11b of the arm 11.
