Title:
SEATBELT RETRACTOR AND SEATBELT DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/005957
Kind Code:
A1
Abstract:
This seatbelt retractor is provided with: a spool for winding a seatbelt; a lock mechanism that allows rotation of the spool during non-operation and prohibits rotation of the spool in the pulling-out direction of the seatbelt during operation; a first energy-absorbing mechanism that deforms due to the rotation of the spool in the pulling-out direction and the rotation prohibition by the lock mechanism; a power transmission mechanism that adds a second load produced by the power of a motor to a first load produced by the deformation of the first energy-absorbing mechanism; and a second energy-absorbing mechanism that reduces the limit load, which is increased by the addition of the second load to the first load, by undergoing deformation.
