DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety belt used for a child safety seat for an automobile, and more particularly, to a safety belt used for a child safety seat for an automobile which enhances the safety of a child in a collision. About the belt.

[0002]

2. Description of the Related Art In recent years, there has been an increasing awareness of improving the safety of automobiles, and newborn babies, babies, infants, and school children (hereinafter, collectively referred to as young children). Various types of child safety seats for automobiles have been developed as devices for ensuring safety in children's automobiles when the vehicle is mounted on a car.

[0003] The Japanese Industrial Standards stipulates a detailed standard for this automobile safety child safety seat in [Automobile Supplies-Child Protection System: JIS-D 0401-1996].

According to the types and classifications of the child protection devices of Japanese Industrial Standards, the types of child protection devices are "beds for infants (including newborn babies)", "sheets for infants (for both front and rear)" and It is divided into "children's seats".

[0005] This category depends on the weight range of the young,
W1 (less than 10 kg), W2 (9 kg or more and 18 kg or less), W3 (15 kg or more and 25 kg or less), W4 (22 kg or less)
kg to 36 kg). Also, W
1. In order to satisfy the safety standards in the category of W2, when the seat is used as a rearward facing infant seat, the maximum tilt angle of the backrest portion is determined in consideration of the rebound of the infant seat at the time of collision. A mechanism is required so that the angle formed between the surface of the surface and the vertical plane does not exceed 60 °.

Here, a child protection apparatus generally called W1 is fixed to a vehicle seat so that the target age is 0 to 10 months, and is directed sideways or backward with respect to the traveling direction of the vehicle. A device. In addition, a child protection device called W2 has a target age of about 6 months to 3, 4 years old,
A device that is fixed to a vehicle seat so as to face forward or backward with respect to the traveling direction of the vehicle (generally, it is commercially available as a child seat). Furthermore, a child protection device called W3 has a target age of 3,
4 to 6 years old, a device that raises the seat of school children (generally,
It is commercially available as a booster). W1 and W2 of such a child protection device for an automobile, respectively.
Various products have been developed for the device applied to W3.

On the other hand, the mounting rate of such a child protection device in today's Japanese car society is extremely low as compared with Europe and the United States. The first cause of this is considered to be insufficient recognition of the degree of danger to the parent's car. Second, when a child refuses to sit on such a child protection device, the child may not be seated on the child protection device. This leads to the aforementioned lack of awareness of the risk of the parent's car.

Therefore, as a method for solving these problems, first, it is necessary to reform the recognition of the degree of danger to the parent's car. In this regard, active public relations activities by the government are expected. It is also considered important to enact mandatory child protection devices when driving young people in cars.

[0009] In addition, when a child hates sitting on a child protection device, the child protection device is always mounted on a child protection device from the time of a newborn baby or an infant who is unreliable. Consciousness can be developed in a car, regardless of likes or dislikes when riding a car.
This is extremely important in a social sense.
So, when you ride a car like this for young people,
In order to develop a consciousness that the child must always be seated in a child protection device, a child protection device that can be used consistently from a newborn / infant to a school child is desired. In other words, it suffices if one child protection device can be used for both the above-described use as W1 and use as W3.

Here, when a five-point safety belt disclosed in Japanese Patent Application Laid-Open No. 7-69109 is applied to a child protection device that can use W1 to W3, there are the following problems.

When the child protection device is used as W1,
In a child protection device, a bed surface is formed. The child protection device having the bed surface is mounted laterally to the traveling direction of the vehicle. Therefore, when a vehicle collides, an impact is applied to the child in the lateral direction. However, in the five-point safety belt disclosed in Japanese Patent Application Laid-Open No. 7-69109, the structure is considered only for the impact applied to the body of the young person in the forward or rearward direction. Therefore, when an impact is applied in the lateral direction, there is a problem that the shoulder belt comes off the shoulder of the young person.

Accordingly, an object of the present invention relates to a safety belt used for a child safety seat for an automobile, and can safely protect against a lateral impact force when the child safety seat for an automobile is used in a bed state. An object of the present invention is to provide a safety belt used for a child safety seat for an automobile capable of holding a child.

[0013]

A safety belt used in a child safety seat for an automobile according to the present invention comprises:
A safety belt for a child safety seat for a vehicle, which is fixed to the above-mentioned vehicle seat using a seat belt attached to the vehicle seat and supports the child with a seat portion and a backrest portion, the one end being provided. Is fixed to a substantially central portion of the seat portion, has a first connecting member at the other end, and a crotch belt attached to the crotch portion of the child, and on one side of the seat portion, one end is the seat portion. A first waist belt fixed to a side portion and having a second connecting member detachably connected to the first connecting member at the other end, and a first waist belt attached to the waist of the child;
On the other side of the seat portion, one end is fixed to a side portion of the seat portion, and the other end has a third connecting member detachably connected to the first connecting member, and is mounted on the waist of the child. A second waist belt, a first shoulder belt having one end fixed to the backrest portion, and the other end connected to the second connection member, so that the second waist belt can be worn on one shoulder of the child; A second end, one end of which is fixed to the backrest portion and the other end of which is connected to the third connection member, so that the second connection member can be attached to the other shoulder of the second member.
A shoulder belt, a first shoulder belt pad made of a flexible member attached to the first shoulder belt, a second shoulder belt pad made of a flexible member attached to the second shoulder belt, and the first shoulder belt pad And a shoulder belt connecting member having a connecting member that can be connected to and separated from the second shoulder belt pad.

As described above, by providing the shoulder belt connecting member for connecting the first shoulder belt and the second shoulder belt, even when the child safety seat for a vehicle is in a bed state and the child is supported, Also, the lateral force applied at the time of the collision makes it possible to hold the child safely in the child safety seat for an automobile without the shoulder belt coming off the child.

Preferably, a first auxiliary belt for connecting the first shoulder belt pad and the first waist belt,
The second for connecting the shoulder belt pad and the second waist belt
And an auxiliary belt. Thus, the first shoulder belt pad and the second shoulder belt pad can be prevented from being shifted, and the young person can be reliably supported.
