AI Technical Summary
Existing seat belt retractors fail to properly detect vehicle acceleration and inclination when installed at angles other than horizontal, leading to improper locking operations due to sensitive sensor lever interactions and restricted spool rotation.
A vehicle sensor device with a rotatable sensor housing and ball mechanism that allows the sensor lever to linearly reciprocate the pilot lever, maintaining normal operation across a wide range of backrest angles by using a ball and sensor housing to sense changes in inclination and acceleration.
The solution ensures consistent locking and unlocking of the seat belt webbing regardless of the backrest's angle, allowing normal operation from 10° forward to 90° rearward, enhancing the seat belt retractor's adaptability and functionality.
