[0001]

[Industrial applications]

 The present invention relates to an automobile seat for an infant, which is placed on a seat of an automobile to ensure the safety of the infant when the automobile collides.

[0002]

[Prior art]

 A conventional car seat for infants of this type is shown in FIG. The infant seat has a seat 2 on which an infant sits on a synthetic resin seat body 1, and a bicycle saddle-shaped support plate 3 into which the thighs of a baby are inserted on both left and right sides. is there.

A lower end of the support plate 3 is attached to a front portion of the seat 2, and an upper portion of the other support plate 3 is inserted through a belt 5 into a belt insertion hole 4 formed in a back support portion of the seat body 1. It is inserted and supported by the seat body 1.

Then, the thighs are extended forward from both sides of the support plate 3 so that the thighs are seated on the seat 2 and the neck is extended between the parallel belts 5 to prevent the infant from jumping forward. It is the one.

This infant car seat is a waist belt portion of a three-point seat belt 6 as shown in FIG. 7 when it is attached to a car seat by a three-point seat belt installed in the car. 6a and the shoulder belt portion 6b are bundled and supported by a clip 7.

As shown in FIG. 8, the bundled belt 6 is inserted into a belt insertion hole 8 provided in a lower rear portion of the seat body 1, and a tongue 9 provided on the seat belt 6 is fixed to a buckle of an automobile. Then, the seat body 1 is attached to the original seat 10 of the automobile.

As a seat belt device for ensuring the safety of an infant riding in a car, a seat belt device disclosed in Japanese Utility Model Laid-Open No. 61-154144 is known.

[0008]

[Problems to be solved by the device]

 However, at present, three-point seat belts are widely used in general passenger cars, and when such an infant car seat is attached to the seat 10 of an automobile by the three-point seat belt, As described above, the clip 7 for bundling the waist belt portion 6a and the shoulder belt portion 6b of the seat belt 6 is required as described above, and the labor for bundling the clip 7 as described above is required.

Further, when the tongue 9 of the thus bundled seat belt 6 is inserted into the belt insertion hole 8 of the seat body 1 and is fastened to the buckle, the seat belt 6 is loosened to the bundled seat belt 6. And the length of the tongue 9 must be adjusted so that it can be attached to the buckle.

In order to make this adjustment, it is necessary to remove the clip 7 from the seat belt 6, and the length adjustment of the seat belt 6 and the attachment / detachment of the clip 7 are repeated to adjust the seat belt 6 to an appropriate length. Adjustment work was required, which was very troublesome.

The present invention is to solve the above-mentioned problems of the conventional car seat for infants. Even a car provided with a three-point seat belt does not need a clip for binding the seat belt and is troublesome. It is an object of the present invention to provide an automobile seat for infants, which does not require a special seat belt adjustment work and is easily removable.

[0012]

[Means for Solving the Problems]

 The present invention is characterized in that a predetermined gap is provided at the rear of a seat body for an infant, and a seat belt engagement / disengagement portion having a shape similar to that of an adult upper limb is integrally provided.

[0013]

In the infant car seat of the present invention, the seat belt engagement / disengagement portion having the same shape as the upper limbs of a large person, to which the three-point seat belt is fastened, is located between the seat body for the infant. Since a three-point type seat belt is inserted in this gap because it is provided on the back of the seat body, the shoulder belt part of this seat belt is attached to the latching part of the seat belt disengagement part, The belt portion locks near the lower end of the seat belt engagement / disengagement portion.

Therefore, the three-point type seat belt becomes a state in which the engaging / disengaging portion of the infant car seat can be held, similarly to the case where an adult person is usually worn, and by attaching / detaching a normal seat belt, Car seats for infants can be installed and removed.

[0015]

【Example】

 An embodiment of the present invention will be described below with reference to FIG. 1 and FIG.

A seat belt engaging / disengaging portion 12 is integrally formed on the back surface of the infant seat body 1 with a predetermined gap 11 provided between the seat body 1 and the seat body 1, for example, a width such that a hand can be inserted. Be done. The seat body 1 and the seat belt engagement / disengagement portion 12 are formed of a synthetic resin such as an acrylic / butadiene / styrene copolymer (ABS resin).

The seat belt engaging / disengaging portion 12 has a shape similar to that of an adult upper limb, and the width of the left and right is narrowed near the upper end thereof, and the hooking portion 13 is formed in the same size and shape as a shoulder. The shoulder belt portion 6b of the seat belt 6 is hooked on the hooking portion 13.

The lower portion of the seat belt engaging / disengaging portion 12 is formed to have the same size and shape as the waist, and the waist belt portion 6a of the seat belt 6 is hooked on this portion. .

As shown in FIG. 3, the hooking portion 13 has a hooking groove 14 having claw-shaped portions protruding from both sides, and the shoulder belt portion 6 b of the seat belt 6 is placed in the hooking groove 14. It is preferable that the shoulder belt portion 6b can be inserted and prevented from moving.

Further, the seat belt engagement / disengagement portion 12 does not need to be provided with meat on the entire surface, and as shown in FIG. 4, the inside is lightened and only the frame has meat, or both left and right sides as shown in FIG. There is no problem even if the meat is removed and only the upper and lower frames have meat. In this way, the weight of the seat body 1 is reduced and the material thereof is saved.

By inserting the three-point type seat belt 6 into the predetermined gap 11 between the seat belt engaging / disengaging portion 12 and the seat body 1 and attaching the tongue 9 to the buckle, the shoulder of the seat belt 6 The belt portion 6b can hook the hooking portion 13 of the seat belt engaging / disengaging portion 12 as described above.

At the same time, the waist belt portion 6a of the seat belt 6 latches around the lower end of the seat belt engaging / disengaging portion 12, and the latch portion 13 or the latch groove 14 of the shoulder belt portion 6b is latched. In combination, the infant car seat can be securely fixed to the car seat 10.

As described above, since the clip 7 is not used for the three-point seat belt 6 unlike the conventional automobile seat for infants, a part of the seat belt 6 by the clip 7 is stretchable. The length adjustment of the seat belt 6 due to the loss of the seat belt, and a lot of trouble and trouble associated therewith are eliminated.

[0024]

[Effect of device]

 As described above, the present invention eliminates the need to use a clip for bundling seat belts when attaching to a vehicle seat with a three-point seat belt that is widely used as a vehicle seat belt.

Therefore, since the elasticity of the seat belt is maintained, it is not necessary to adjust the length of the bundled seat belt by repeating the actual matching, and the attachment / detachment of the vehicle seat for infants is conventionally performed. It is as easy as

[0026] In this infant car seat, even the upper hooking portion of the seat belt engaging / disengaging portion is hooked by the shoulder belt portion of the seat belt, so that the infant car seat is in the forward leaning state. There is no danger of becoming.
