[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a view showing a state in which a child supporter 1 of the present invention is attached to a normal adult seat belt, a child is seated on a car seat, and a seat belt 2 is worn. FIG. 2 is an overall view of the child supporter 1.

When the child supporter 1 is attached to the seat belt 2 and worn, the horizontal support portion 3 for loosely pressing the abdomen of the human body against the seat, the inclined support portion 4 for loosely pressing the human chest to the seat, and the horizontal support portion described above. It comprises a connecting member 5 for connecting the portion 3 and the inclined support portion 4 to maintain the mounting angle of the inclined support portion 4 with respect to the horizontal support portion 3. The horizontal support portion 3 and the inclined support portion 4 use hard rubber plate members 3a and 4a on the side in contact with the seat belt 2. Also, sponge-like urethanes 3b and 4b covered with cloth are used on the side that comes into contact with the human body. The hard rubber plates 3a, 4a and the sponge-like urethanes 3b, 4b are joined with an adhesive or the like.

The connecting member 5 is made of hard rubber and is connected to the two plate members 3a and 4a with an adhesive, a screw, or the like, or is formed integrally with the two plate members 3a and 4a. At this time, it has been experimentally determined that the inclination angle of the inclined support portion 4 with respect to the horizontal support portion 3 is preferably set to 20 °. However, it can be changed according to the age and height of the child. Note that the connecting member 5 may be made of cloth so that the horizontal support portion 3 and the inclined support portion 4 can be freely adapted to the human body.

The horizontal support portion 3 is formed to be long in order to support the child's abdomen over a wide area, and has an arc shape along the abdomen as shown in FIG. 3 in order to hold the child in a predetermined position when the automobile rolls. Is formed. The inclined support portion 4 is formed shorter than the horizontal support portion 3 so that the child can move both hands freely.

A mechanism 6 for attaching and detaching to and from the seat belt 2 is provided near both ends of the plate 3a of the horizontal support 3 and the plate 4a of the inclined support 4. It has been experimentally determined that the attachment / detachment mechanism 6 is preferably inclined by 45 ° with respect to the upper and lower sides of the plate member 4a only with respect to the attachment / detachment mechanism 6A on the right side of FIG. As an example of this attachment / detachment mechanism, a so-called patch lock will be described with reference to FIGS.

FIG. 4 is an enlarged view of the patchin tablet, and FIG. 5 is a cross-sectional view taken along the line BB of FIG. On the upper sides of the plate members 3a and 4a, a downwardly engaging L-shaped stopper 7 is attached by a set screw 11 and a nut 12, and the lower end 7a has a hook shape. On the lower sides of the plate members 3a and 4a, a stopper 8 having an L-shaped cross section is mounted at a position facing the stopper 7 by a set screw 11 and a nut 12. A predetermined space is provided between the lower end of the stopper 7 and the upper end of the stopper 8 so that the seat belt 2 can be inserted between the two stoppers 7 and 8.

A boss 8a protrudes outward near the upper end of the stopper 8, and a manually operated lever 9 is pivotally supported on the boss 8a. When the lever 9 rotates counterclockwise in FIG. 5 and turns downward in FIG. 5 at a position slightly deviated from the pivot point, the locking bracket is located at a position below and to the right of the pivot point of the lever 9. 10 is pivoted. The locking member 10 is formed so as to be lockable on a lower end hook 7 a of the stopper 7. When the lever 9 is rotated clockwise upward by manual operation, the tip of the latch 10 is hooked on the hook portion 7a, and the lever 9 is rotated counterclockwise downward, the tip of the latch 10 is rotated. Is engaged with the bottom of the hook portion 7a by dropping, so that the hooking state is maintained and the hook portion 7a does not fall off the hook portion 7a. Then, by closing the patch lock, a predetermined interval between the two stoppers 7 and 8 is closed so that the seat belt 2 does not separate from the child supporter 1.

When tension is applied to the seat belt 2 inserted between the two fasteners 7 and 8 at the time of wearing, one of the two fasteners 7 and 8 is pulled by the seat belt 2. . However, since a closed loop is formed by the plate material 3a (4a) and the stopper 10, the pulled force is supported by each of the loop-shaped members, so that it is not easily broken. The stoppers 7, 8 may be made of hard rubber and formed integrally with the plate members 3a, 4a.

In FIG. 1, of the four attachment / detachment mechanisms 6 shown in FIG. 1, the attachment / detachment mechanism 6A on the right side of the inclined support portion 4 has a seat belt inside a stopper 7 provided on the upper side as shown in FIG. An arc-shaped member 13 that guides 2 smoothly to the inclined support portion 4 is attached. As a result, the angle of the seat belt 2 does not suddenly change, and it is possible to prevent an impact force from being applied to one place at the bent portion of the side of the seat belt 2, so that the strength of the seat belt is not deteriorated and the life of the seat belt can be extended. It becomes possible. As a method for preventing the concentration of the impact force on the sheet belt 2, as shown in FIG. 7, a semi-conical member 14 is replaced with the arc-shaped member 13 at the mounting position of the arc-shaped member 13 with the large diameter side up and the pointed end down. When the seat belt 2 is attached, the upper side end of the seat belt 2 floats from the plate 4a, and the lower side end comes into contact with the plate 4a, so that the seat belt 2 can smoothly change the angle. .

As a mechanism for attaching and detaching the child supporter 1 to and from the seat belt 2, a mechanism shown in FIGS. 8 and 9 can be used other than the packing lock. In this embodiment, the tongue pieces 3c, 4c, 3d, 4d are integrally formed on the plate members 3a, 4a by changing the phase of the mounting position from the upper and lower sides. The tongue pieces 3c, 4c are formed so as to extend downward from the upper sides of the plate members 3a, 4a in an L-shaped cross section to have a length of about 2/3 or more of the plate width of the plate members 3a, 4a. The tongue pieces 3d, 4d are formed in a state of rising from the lower side to the upper side of the plate members 3a, 4a in an L-shaped cross section with a length of about 2/3 or more of the plate width of the plate members 3a, 4a. The tongue pieces 3c, 4c and the tongue pieces 3d, 4d have a gap larger than the thickness of the seat belt 2. The sheet 3a of the horizontal support portion 3 is further formed with one tongue piece from the lower side, and the inclined support portion 4 is further formed with one tongue piece from the upper side. It is also possible to distribute the force received from the belt 2 between the two tongue pieces.

Also, as shown in FIGS. 10 and 11, the mounting positions of the tongues provided on the upper and lower sides of each support portion are the same, and one tongue, for example, 3c, 4c is seated on the tongues 3d, 4d. It is also possible to have a gap larger than the thickness of the belt 2 and to be located farther than the plate members 3a and 4a. In the child supporter 1, there are provided several types of connecting members 5 having different dimensions and inclination angles to correspond to the age and height of the child. In the above description, all the descriptions have been made for children. However, it is needless to say that the present invention can be applied to short adults and elderly people.
