DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

[0015] In describing the embodiments, technical details that are well known in the technical field to which the present invention pertains and are not directly related to the present invention will be omitted in order to more clearly convey the gist of the present invention without obscuring it.

[0016] For the same reason, some components in the accompanying drawings are exaggerated, omitted, or illustrated in a schematic manner. Also, the size of each component does not entirely reflect the actual size. The same reference numerals are given to the same or corresponding components in each drawing.

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A chest seat belt for a vehicle passenger according to a preferred embodiment of the present invention will now be described with reference to FIGS.

[0018] FIG. 1 is a perspective view of a chest seat belt for a vehicle passenger according to a preferred embodiment of the present invention.

[0019] Referring to FIG. 1, a chest seat belt (100) according to a preferred embodiment of the present invention includes a belt portion including a buckle (55) that wraps around a portion of a person's torso and can be fastened by adjusting the circumference, and a wire portion (90) made of a flexible material and connected to the belt portion at one end and to the ceiling of the vehicle or near the ceiling at the other end. The wire portion (90) is hollow, and when an impact occurs due to an accident or a sudden change in acceleration greater than a preset value occurs, an airbag installed at the inner end of the hollow portion bursts and air is charged at a high pressure, thereby supporting the wearer in a state where its flexibility is greatly reduced.

[0020] Here, the belt portion includes the front left engraving (50), the buckle (55), the rear left engraving (60), the rear right engraving (65) and the front right engraving (70), and functions to wrap a part of the wearer's torso. The belt portion is usually made of a flexible fabric, and is made so that the wearer does not feel uncomfortable while it is wrapped around the human body.

[0021] In addition, one end of the wire portion (90) is connected to the belt portion, and a wire length adjustment portion (80) is provided, and the wire length adjustment portion (80) includes at least one elastic member and operates so that the length of the wire included in the wire portion (90) is appropriately adjusted by the action of an external force through the action of the elastic member.

[0022] Also, the other end of the wire portion (90) is connected to the ceiling of the vehicle or its vicinity. Referring to FIG. 2, the device includes an electromagnetic head (96) that is attached to the ceiling of the vehicle by magnetic force, a spherical rotating ball (98) that is surrounded by the electromagnetic head (96) and has a part of its upper portion protruding outside the electromagnetic head (96) and rolls and contacts the ceiling of the vehicle, an airbag impactor (95) that is spaced a certain distance from the lower end of the rotating ball (98) and has a pointed protruding impact portion formed on the outer surface opposite to the surface facing the rotating ball (98), and an airbag (94) that is installed at the upper end of the hollow of the wire portion (90) to face the airbag impactor (95) at a certain distance. When an impact occurs due to an accident or a sudden change in acceleration occurs that is greater than a preset value, the airbag impactor (95) descends due to the interaction between the electromagnetic head (96) and the rotating ball (98) to explode the airbag (94).

[0023] As described above, when a sudden change in acceleration occurs due to an accident or other circumstances, if the airbag (94) explodes due to the interaction between the electromagnetic head (96) and the rotating ball (98), the air inside the wire portion (90) is charged with high pressure as shown in Figures 3(a), (b), and (c), and the wire portion (90) becomes unable to be flexible and is therefore able to support the wearer.

[0024] In addition, Figures 4 to 9 show, in numerical order, a front view, rear view, left side view, right side view, top view, and bottom view of a chest seat belt (100) according to a preferred embodiment of the present invention (directions are indicated based on the drawing direction).

[0025] Referring to each of Figures 4 to 9, the front right engraving (70) and the front left engraving (50) cover the wearer's chest, the rear right engraving (65) and the rear left engraving (60) cover the wearer's back, and after adjusting the degree to which the front left engraving (50) and the rear left engraving (60) overlap, the belt can be fastened to the wearer's body by adjusting the degree to which the belt presses against the wearer's body and fastening it with a buckle (55).

[0026] In addition, to connect the belt portion to the vehicle, a flexible wire portion (90) is used, and as described above, one end of the wire portion (90) is connected to the belt portion and the other end is connected to the ceiling of the vehicle or near the ceiling.

[0027] At this time, the other end of the wire portion (90) moves while attached to the ceiling of the vehicle according to the wearer's movements. This is made possible by the magnetic force and rolling contact of the rotating ball (98) and the electromagnetic head (96) contained in the head portion (97) at the other end of the wire portion (90).

[0028] FIG. 10 is a view showing an example of a vehicle occupant wearing a chest seat belt according to a preferred embodiment of the present invention.

[0029] Referring to FIG. 10, it can be seen that a person in a vehicle is wearing the chest seat belt (100) of the present invention, and the wire portion (90) is attached to the vehicle ceiling (222) by the head portion (97) installed at the other end.

[0030] Meanwhile, the present specification and drawings disclose preferred embodiments of the present invention, and although specific terms are used, these are used in a general sense to simply explain the technical contents of the present invention and to aid in the understanding of the invention, and are not intended to limit the scope of the present invention. It is obvious to those skilled in the art to which the present invention pertains that, in addition to the embodiments disclosed herein, other modifications based on the technical ideas of the present invention can be implemented. [Industrial Applicability]
