Problems solved by technology

[0006] However, when the electric motor is driven by the occupant pulling out the seat belt as described above, since the spool and the electric motor are directly connected through the reduction mechanism, when the occupant pulls out the seat belt, the occupant will temporarily feel the pulling out of the seat belt. discomfort caused by heavy feeling
Therefore, the occupant cannot comfortably perform the wearing action of the seat belt.

Abstract

An electric motor-driven seat belt retractor is provided, which can reduce the temporary heavy feeling of pulling out the seat belt and suppress discomfort when pulling out the seat belt. When the safety belt (6) is not worn, the protruding part (21) of the internal gear (17) is set on the central position of the circumferential direction between the adjacent protruding parts (25) by the elastic force of the two springs (26, 27) . Due to the rotation of the spool (13) to the pull-out direction of the safety belt, the internal gear (17) is also rotated to the pull-out direction of the safety belt, thereby the reduction mechanism (15) cannot carry out power transmission, and the spool (13) and the sun gear (13) are connected to the sun gear ( The direct connection between the electric motors on the 16) is disconnected, reducing the temporary heaviness of pulling out the seat belt. When the internal gear (17) rotates by a predetermined angle, the protruding part (21) abuts against the protruding part (25) to stop the internal gear (17) from rotating. Thus, the reduction mechanism (15) cannot perform power transmission, and the reel (13) and the electric motor are directly connected through the reduction mechanism (15).

Description

technical field [0001] The present invention relates to the technical field of a seat belt retractor and a seat belt device having the seat belt retractor. The seat belt retractor is used for seat belts equipped on vehicles such as automobiles and using seat belt restraints to protect occupants. The device rotates the reel through the driving force of the motor, so as to wind up and pull out the seat belt. Background technique [0002] In the past, the seat belt device equipped on automobiles and other vehicles, in the event of a large deceleration of the vehicle in the event of a vehicle collision, restrains the occupant with the seat belt to prevent the occupant from inertial movement from the seat, thereby protecting crew. The safety belt device is provided with a safety belt retractor, which uses a reel to wind up and pull out the safety belt, and prevents the safety belt from being pulled out in an emergency. [0003] Among such seatbelt retractors, conventionally, a ...
