Embodiment Construction

[0042] figure 1 A side view of a vehicle seat with a seat belt retractor is schematically shown. The vehicle may be a passenger car or a truck, in particular a partially autonomous or fully autonomous motor vehicle. The vehicle seat has a seat portion 5 and a backrest 4 which can be figure 1 The substantially upright initial position depicted in solid lines is adjusted forward and backward. The initial position may be optimized for occupant seating and maneuvering the vehicle. The backrest 4 can be folded forward on the seat 5 in order to free up space. The backrest 4 can be adjusted backwards to a position close to the horizontal maximum inclination angle, at which the occupant can rest. With reference to the heading direction of the vehicle, the position of maximum inclination may correspond to an inclination close to 180°, for example approximately 170°. The backrest 4 can be adjusted to any intermediate position between the predetermined initial position and the posit...

Abstract

The invention relates to a safety belt retractor for a vehicle seat. The safety belt retractor comprises a vehicle sensing device, wherein the vehicle sensing device comprises a rotatable sensitive seat having a first rotation axis. The safety belt retractor further comprises a rotatable transmission pulley, wherein the transmission pulley is provided with a second rotation axis; the first rotation axis and the second rotation axis have an intersection point; the transmission pulley is provided with a push rod; the push rod is offset relative to the second rotation axis and extends out of thebody of the transmission pulley; the push rod and the sensitive seat are provided with a contact point; a connecting line is formed between the intersection point and the contact point; and the connecting line and the first rotation axis form an included angle larger than 60 degrees. The invention also relates to complete equipment for the vehicle seat. The complete equipment comprises two safetybelt retractors. The safety belt retractor is simple in structure, compact in size, small in the number of parts and easy to manufacture and install.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle safety, and more particularly, to a seat belt retractor for a vehicle seat and a kit including two such seat belt retractors. Background technique [0002] In the technical field of vehicle safety, a vehicle safety belt can be a safety protection device used to protect the occupant when an emergency occurs in the vehicle, such as emergency braking, collision or overturning, wherein the occupant can be restrained by a belt-shaped webbing, and the webbing can pass through the safety belt. The mandrel with retractor retracts and can be fixed to the vehicle with a deadbolt. Vehicle seat belts can be an important component in a vehicle's passive safety system. A vehicle may be, for example, a passenger car, a truck or another means of transportation. [0003] With the development of vehicle technology, users have higher and higher requirements for vehicle comfort, and the same is true for th...
