Description

Technology Field

[0001] The present invention relates to a seat belt height adjustment device, and more specifically, to a seat belt height adjustment device provided in a vehicle seat to adjust the height of a guide ring to which the seat belt is connected, thereby allowing the height of the seat belt and guide ring to be adjusted to suit the physique of the occupant, and in particular, to a seat belt height adjustment device that allows a child who is relatively shorter than an adult to wear the seat belt without a separate child seat. Background Technology

[0003] Generally, seat belts are installed in vehicle seats to ensure the safety of the occupants. One end of the seat belt is fixed to the body and the other end is connected to a retractor, while the middle section is inserted into an anchor fixed to the body. The seat belt is also equipped with a fastening device that engages with a buckle installed on the seat.

[0004] In other words, while the seat belt is pulled by the retractor, it remains fixed to the body around the anchor.

[0005] However, although conventional seat belts are shipped from car manufacturers with fixed lengths and heights, people with relatively large or very small physiques find it uncomfortable to wear them because body types vary.

[0006] In addition, for children, the high height of the seatbelt creates the persistent inconvenience of having to provide a separate dedicated seat.

[0007] The aforementioned invention refers to background technology in the technical field to which the present invention belongs, and does not refer to prior art. Prior art literature

[0031] As illustrated in the drawing, the present invention is a height adjustment device (10) (hereinafter referred to as a height adjustment device for convenience of explanation) which is a height adjustment device (10) configured to adjust the height of a safety belt. Accordingly, such a height adjustment device (10) is composed of a guide cap body (20), a guide seat member (30), a control rail body (40), and a guide ring unit (50).

[0033] The above guide cap body (20) is composed of a front panel (21) and a guide frame member (22) that is integrally formed or attached and fixed to the back surface of the front panel (21).

[0034] A guide hole (211) is formed in the front panel (21) to communicate with the guide frame member (22).

[0035] The above guide cap body (20) is formed from a synthetic resin material, and it is also possible to form it from a metal material.

[0037] The guide sheet member (30) is placed on the inner surface of the front panel (21) while closing the guide hole (211), and a guide slit hole (31) is formed.

[0038] The above guide sheet member (30) is formed from a synthetic fiber material or an elastic synthetic resin material.

[0039] The guide sheet member (30) may be attached to the back surface of the front panel (21) or fixed by screw fastening, and it is also possible to fix the connecting bracket (72) by pressing the support bar (60).

[0040] The above guide sheet member (30) prevents foreign substances from entering the inside of the guide cap body (20) and prevents the inside from being visible, thereby improving the aesthetics.

[0042] The above control rail body (40) is placed inside the guide frame member (22) of the above guide cap body (20).

[0043] The above control rail body (40) is composed of a guide control panel (41), a pair of hanging angle rails (42) formed integrally on both sides of the guide control panel (41), and hanging support holes (43) formed in the guide control panel (41).

[0058] The above detachable support member (70) is composed of a pair of fastening caps (711) that are integrally formed or attached and fixed to the inner surface of the front panel (21) of the guide cap body (20), and a fastening bracket (72) that is detachably fastened to the fastening member (71).

[0059] The above-mentioned fastening portion (71) is formed on the front panel (21) while maintaining a certain spacing as shown in the drawing.

[0060] The above-mentioned connecting bracket (72) is formed in a "U" shape and supports the above-mentioned control rail body (40) while connecting and fitting a pair of the above-mentioned connecting caps (711) to secure them.

[0061] The above-mentioned fastening brackets (72) prevent the control rail body (40) from moving or separating from the guide cap body (20), and improve the fixing and supporting forces.

[0063] The above guide cap body (20) is further provided with a driving support guide means (80) to transport and support the above guide ring unit (50).

[0064] The above drive support guide means (80) comprises a fixed bracket member (81) that is fixed by screwing it to the inner surface of the guide protection tube of the guide cap body (20), a transfer support cylinder (82) that has one end screwed to the fixed bracket member (81) that is fixed to the guide protection tube, a transfer bracket member (83) that is fixed by screwing it to the transfer axis of the transfer support cylinder (82) that is fixed to the fixed bracket member (81) and is transferred by the drive of the transfer support cylinder (82), an elastic cushioning support member (84) that is connected and fixed to the transfer bracket member (83) that is connected to the transfer support cylinder (82), and a connection guide member (85) that is connected and fixed to the elastic cushioning support member (84) that is connected to the transfer bracket member (83), and the elastic cushioning support member (84) is the one connected to the transfer support cylinder (82). A cushioning support coil spring (841) with one end screw-fastened and fixed to a transfer bracket member (83), a cushioning bracket (842) with the other end screw-fastened and fixed to the transfer bracket member (83), and the connecting guide member (85) is composed of a guide shaft (851) with one end screw-fastened and fixed to the cushioning bracket (842) which is connected to the cushioning support coil spring (841), and a support structure member (852) with the back side connected and fixed by screw-fastening to the other end of the guide shaft (851) connected to the cushioning bracket (842), and the front side screw-fastened and fixed to the guide ring unit (50).

[0065] The above support structure member (852) is formed as a bar structure and is fixed by being screw-fastened or attached to the guide neck portion of the guide ring unit (50).

[0066] At this time, the guide ring unit (50) is supported by the elasticity of the buffer support coil spring (841), thereby cushioning the transmission of impact.

[0067] In addition, by moving the guide ring unit (50) by driving the transfer cylinder, the position where the safety belt is fastened can be easily adjusted.

[0069] It is preferable to further form inner bearing grooves in the guide hole (211) and to rotatably insert ball bearings into the bearing grooves while also arranging a portion of them to protrude outward, thereby guiding the guide neck portion of the guide ring unit (50) moving along the guide hole (211) so that the ball bearings guide the guide neck portion of the guide ring unit (50) and prevent the guide neck portion from getting caught or rubbing against the inner surface of the guide hole (211).

[0071] It is preferable to further fix a vibrator, which is a vibrator, to the outer surface of the control rail body (40) by screwing it in, so that the guide panel of the guide ring unit (50) is prevented from getting caught on the inner surface and the inner surface of the catch angle rail (42) formed on the control rail body (40) during the movement process inside the control rail body (40).

[0073] It is preferable to further attach and fix an elastic cushioning support panel made of a synthetic resin material having elasticity to the inner surface that contacts the control rail body (40) to the above-mentioned fastening bracket (72), thereby supporting the control rail body (40) by the elasticity of the elastic cushioning support panel, preventing friction, and cushioning the impact transmitted from the outside.
