Abstract: A seat belt retractor (10) has an actuator (14) for unlocking and locking the seat belt retractor (10) An inertial sensor (18) detects changes in vehicle acceleration and interacts with the actuator (14) to lock and unlock the seat belt retractor (10). The inertial sensor (18) has one inertial sensor mass, each mass (26, 27, 29, 30, 32, 33) has a wide portion (70) and a narrow portion (72). Preferably each inertial sensor mass (26, 27, 29, 30, 32, 33) has a high density body (31) embedded in the wide portion (70) of the elastomeric material (34). The inertial sensor mass (26, 27, 29, 36, 32, 33) has a greater density than the elastomeric material (34) Moreover, the elastomeric material (34) at least partially surrounds an exterior circumferential surface (38) of the inertial sensor mass (26, 27, 29, 30, 32, 33).

Abstract: A seat belt buckle assembly including a seat belt buckle, the buckle including: a frame (26) defining a tongue-receiving slot (40); a latch plate (34) operably positioned in relation to the tongue-receiving slot and movable between an unlocked position and a locked position; a latch spring (64) for biasing the latch plate toward the locked position; an ejector mechanism (28) located behind the tongue-receiving slot and rearwardly movable in response to inward movement of a tongue; the ejector including a first portion engageable by the tongue and rearwardly movable to a position beyond the location of the latch plate and a second portion (80) slidably receiving and supporting the latch plate, the second portion remaining in contact with the latch plate, preventing the latch plate from moving to its locked position even when the first portion has moved beyond the latch plate.

Abstract: A web guide (20) having a load absorbing core (30), a hinge and an integral cover (170). The core is covered by a synthetic resin that also forms the integral cover and hinge. The cover is locked into place by tabs integrally formed by the coating material.
