Problems solved by technology

[0007] However, since the ALR function and the BO function are realized by using different components, the ALR function and the BO function cannot be simultaneously realized in one retracting device
[0008] Also, even if two functions are simultaneously performed in one retraction device, it may increase the number of steps to manufacture the retraction device
Also, when both functions are implemented, the number of parts may increase compared to the case where only one function is implemented

Abstract

Disclosed is a retractor for a seat belt including a spool around which a webbing is wound, a frame rotatably coupled with the spool, a flywheel gear provided at a central portion thereof with a driving gear, having one-directional gear teeth formed along an outer circumferential surface thereof, and mounted on one end of the spool, a vehicle sensor locked with the one-directional gear teeth if the frame is inclined at a predetermined angle or more, a lever locked with the one-directional gear teeth if the webbing is withdrawn by a predetermined first length, and separated from the one-directional teeth if the webbing is introduced again so that the webbing is withdrawn by the second length, and an integrated plate including a driven gear, a first plate to adjust the lever according to a withdrawn length of the webbing, and a second plate integrated with the first plate.

Description

technical field [0001] The invention relates to a retractor for a seat belt. More specifically, the present invention relates to a retracting device for a seat belt capable of realizing both an ALR (automatic locking retractor) function and a BO (block out) function. Background technique [0002] In order to prevent occupants of a vehicle or machine from being ejected from the vehicle or machine due to a collision between the vehicles or a collision with another object, the vehicle or machine is provided with various safety devices therein. [0003] Among these devices, a seat belt is a typical device. The seat belt securely secures the lower abdomen or chest of occupants in a vehicle or machine. However, if the collision between vehicles or with another object is severe, the seat belts may not be effective. As a result, the safety of occupants in the vehicle or machine may be compromised. [0004] Therefore, various technologies have been developed so that the seat belt...
