ABSTRACT:
An inertia latch for a vehicle seat backrest 16 is disclosed. The inertia latch includes a wheel 26 having a pinion gear 34 which engages a sector plate 24 by gear teeth 32 which engage sector plate teeth 36. As the backrest 16 is shifted on rapid deceleration, the wheel 26 rapidly drives a locking tooth 38 into engagement with a locking pawl 40 at the lower end of the inertia pendulum 28. Inertia pendulum 28 is rotated upon application of an inertial load into an interlocking relationship with locking tooth 38. A tilt control pinion gear 47 engages a tilt sector plate 48 to adjust the orientation of the seat back relative to the seat bottom.
