Abstract

A seat belt retractor of the present invention is provided with a stopper (16). When a cam follower (16a) of the stopper (16) is located in an arcuate retraction groove portion (22a) or a linear groove portion (22b) of a cam groove (22), a seat belt (4) is withdrawn by an amount exceeding a predetermined amount for the normal belt wearing. A stopper portion (16b) of the stopper (16) is located at an engagement allowing position (B) so as to allow engagement between ratchet teeth (27) of a locking gear (26) and an engaging pawl (24d) of a vehicle sensor (24). When the cam follower (16a) is located in an arcuate protraction groove portion (22c) of the cam groove (22), the maximum amount of the seat belt (4) is wound. The stopper portion (16b) of the stopper (16) is located at an engagement preventing position (A) so as to prevent the engagement between the ratchet teeth (27) and the engaging pawl (24d), thereby preventing end lock.

Description

technical field [0001] The present invention relates to the technical field of a seat belt retractor and a seat belt device using the seat belt retractor. For the occupant, the above-mentioned seat belt retractor is capable of preventing end locking and at least has an emergency locking function. Background technique [0002] The existing seat belt device attached to a vehicle seat such as an automobile prevents the occupant from flying out of the seat by restraining the occupant with the seat belt during an emergency such as a collision with a large deceleration effect on the vehicle. [0003] Generally, such seat belt arrangements have seat belt retractors. As the seatbelt retractor, Japanese Patent Application Laid-Open No. 2001-213275 discloses a seatbelt retractor having the function of an emergency locking type seatbelt retractor (ELR) and a function of an automatic locking type seatbelt retractor (ALR). Seat belt retractor, the function of the above-mentioned emerge...
