Title:
SEAT BACK ANGLE COMPENSATION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2023/221585
Kind Code:
A1
Abstract:
A seat back angle compensation mechanism, comprising: a retractor (100), a sensor compensation mechanism (200), a seat cushion angle sensing inhaul cable (710), a base (720) fixed on a seat cushion framework (500), a first connecting rod hingedly connected to the base (720), and a first spring (740). When the seat cushion framework (500) is subjected to angle adjustment, an angle change of the seat cushion framework (500) is converted into a linear distance change by means of a mechanical angle mechanism on the seat cushion framework (500), the linear distance change is converted into an angle change by means of the seat cushion angle sensing inhaul cable (710), and then the position of the sensor compensation mechanism (200) is adjusted by means of a mechanical mechanism, so as to ensure that a gravity sensing block on the retractor (100) is located at a working position. When the backrest is adjusted, the seat back angle compensation mechanism does not affect the compensation function of the sensor compensation mechanism of the retractor.
