Vehicle seat with belt locking mechanism controlled by seat back orientation

摘要

The apparatus comprises a vehicle seat with an upper frame supported to tilt on a lower frame, an emergency locking mechanism on the upper frame and an orientation device for maintaining a predetermined orientation of the emergency locking mechanism relative to the lower frame independently of the force of gravity when the upper frame tilts on the lower frame. The orientation device includes an elongated flexible driving member extending between the upper and lower frames. The orientation device moves the driving member longitudinally in one direction in response to tilting of the upper frame, and moves the driving member longitudinally in an opposite direction in response to opposite tilting of the upper frame. The orientation device tilts the emergency locking mechanism a controlled amount relative to the upper frame in response to the longitudinal movement of the driving member.
