Problems solved by technology

[0003] However, at this time, due to inertia, the human body will continue to maintain the original state of motion and move forward. In this case, the body parts bound by the webbing may be caused, such as shoulders, collarbone, neck, chest, etc., will be affected by the large webbing. Extrusion force, causing injury to the human body, such as shoulder strangulation, etc.

Abstract

The invention relates to a safety belt retractor and a safety belt device. The safety belt retractor comprises a fixing seat (1), a reel (2) used for reeling a woven belt, a first locking piece (3) connected with the reel (2) and rotating along with the reel (2), a second locking piece (4) used for being matched with the first locking piece (3) so as to lock the reel (2), and buffer devices (5) connected between the second locking piece (4) and the fixing seat (1) so as to allow the second locking piece (4) to rotate within a preset angle range relative to the fixing seat (1). The safety beltretractor can allow the woven belt to be continuously pulled out at the preset length when the pull-out accelerated speed of the woven belt exceeds a preset value, so that the squeezing force appliedby the woven belt to the human body is buffered, and the human body is prevented from being harmed by the woven belt.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a seat belt retractor and a seat belt device. Background technique [0002] The vehicle seat belt device plays an important role in protecting the safety of passengers as a passenger protection device together with the airbag. The safety belt device can protect the passenger from leaving the seat or being thrown out of the vehicle when the vehicle collides or rolls over, preventing the passenger from being injured again. In the existing safety belt device, when the vehicle is suddenly impacted by a large external force or the vehicle is braked in an emergency, and the acceleration of the webbing pull out is too large and exceeds the preset value, the retractor will be locked immediately to prevent the webbing from being pulled out. Pull out to secure the passenger on the seat and prevent the passenger from being thrown out. [0003] However, at this time, due to inertia, the h...
