摘要： The safety belt retractor of this invention has a belt-sensitive mechanism and a vehicle-sensitive mechanism, both mounted on an actuating mechanism. The actuating mechanism includes a mounting plate slidably mounted on the reel shaft for limited rotation and a flywheel having ratchet teeth. The vehicle-sensitive mechanism includes a pendulum assembly and an actuating pawl. When the pendulum assembly oscillates, it lifts the actuating pawl which engages the ratchet flywheel, causing the mounting plate to rotate and actuate a locking pawl. The belt-sensitive mechanism includes a pinion gear and a spur gear which is driven by the reel shaft. When withdrawal of the safety belt exceeds a predetermined level of acceleration, the flywheel lags in rotation and causes the pinion gear to move along an arc of the spur gear, causing the mounting plate to rotate and actuate the locking pawl. Rotation of the ratchet flywheel may be synchronized with rotation of a ratchet locking wheel to facilitate immediate engagement of the locking pawl with the ratchet locking wheel.

摘要： A vehicle sensitive safety belt retractor is provided with actuating means responsive to acceleration of the vehicle for directly engaging with ratchet means mounted for interaction with a belt strap reel of the retractor, and thereby preventing protraction of the belt. The actuating means includes a unitary tipping inertia and locking member which is tippable from its position of rest so as to engage the ratchet means. The center of gravity of the unitary member passes over its pivot point on tipping of the member into locked position, so that it can only be returned to its stable, non-tipped position on movement of the ratchet means which it has engaged in a belt retraction direction. In one embodiment, a plurality of such unitary members are used in association with the single ratchet.

摘要： A seat belt retractor of the inertia type comprises a rotatable shaft with a cam-surface driven thereby. A locking element movable on the cam surface is positively displaced by a control element fitted in a recess thereof and acting from an inertia element. The locking element, when driven by the inertia member, engages with the teeth on an annular locking ring to stop retraction of the seat belt attached to the shaft. The inertia element may be spring preloaded and a locking wheel may be provided to provide alternative locking torque for the inertia element when the car assumes a roll-over condition in which the seat belt would not ordinarily retract quickly.
