Seatbelt retractor and seatbelt assembly

A seatbelt retractor for installation in a seat, the seatbelt retractor comprising an adaptive vehicle sensing device actuated by its own gravity and a vehicle sensing adaptive suppression device for suppressing the adaptive vehicle sensing device, wherein the vehicle sensing adaptive suppression device includes a suppression component having a stopping portion, and the adaptive vehicle sensing device has a corresponding stopping portion cooperating with the stopping portion, the stopping portion being capable of being combined with the corresponding stopping portion to lock the adaptive vehicle sensing device, wherein

• the seatbelt retractor further includes an engagement control device for controlling the engagement state between the vehicle sensing adaptive suppression device and the adaptive vehicle sensing device,
• wherein when the engagement control device receives an activation signal, the engagement control device is activated and applies a driving force to the suppression component of the vehicle sensing adaptive suppression device to prevent the stopping portion of the suppression component from engaging with the corresponding stopping portion of the adaptive vehicle sensing device, thereby preventing the adaptive vehicle sensing device from being locked;
• wherein when the engagement control device receives a deactivation signal, the engagement control device is deactivated and cancels the driving force applied to the suppression component of the adaptive vehicle sensing device to prompt the suppression component not to move.
