Description

Technical Field

[0001] This utility model mainly relates to the field of seat belt adjustment technology, specifically to a knob-type seat belt height adjustment component. Background Technology

[0002] Rotary seat belts are typically used in racing cars such as bucket seats. Bucket seats and rotary seat belts usually need to be matched according to the driver's height. When different drivers use this type of seat belt, the shoulder strap of the seat belt may not be able to restrain the shoulders of shorter drivers or may put pressure on the shoulders of taller drivers.

[0003] The inventor proposes a knob-type seat belt height adjustment component. Compared with the smaller shoulder strap opening in existing bucket seats, when drivers of different heights use five-point seat belts on such products, the shoulder strap cannot effectively fit the shoulders of shorter drivers or puts pressure on the shoulders of taller drivers. This product can effectively match the shoulder fixation needs of drivers of different heights by changing the fulcrum height of the shoulder strap. Utility Model Content
