    摘要： Retractable safety belt apparatus in which a strap is extended from a reel to a selected length and in which the apparatus is thereafter locked automatically to prevent further extension of the strap. Disclosed are: various mechanisms for controlling the operation of the extension-preventing device, including mechanisms driven by the reel and mechanisms responsive to strap tension; different types of strap clamps which open automatically during retraction of the strap and close automatically after desired extension of the strap; mechanisms which facilitate retraction of the strap; a mechanism which temporarily disables the extension-preventing device to permit the user to lengthen the belt after it has been fastened; and a belt fastener which ensures that the extended strap will always retract a bit after the belt is fastened.

    摘要： A seat belt reel urged into wound position is prevented from unwinding by a lock bar engaging ratchet teeth formed on the reel. A reset cam on a speed reducing gear mechanism driven by the reel holds the lock bar away from the ratchet teeth when the belt is fully wound to permit initial unwinding of the belt. A pair of disks rotating with the reel are viscously connected to a disk pivotally mounted on the reel shaft, so that the pivotal disk is urged to rotate with the reel. A finger on the pivotal disk holds the lock bar out of engagement with the ratchet teeth during initial unwinding of the belt. Upon interruption of the unwinding movement, a spring urges the pivotal disk to pivot to release the lock bar and to cause the lock bar to engage the ratchet teeth so that further unwinding of the reel is prevented. The reset gear mechanism includes an inner gear eccentrically mounted on the reel shaft and restrained from rotation so that it moves in an orbital path. An outer gear is provided with a ring of teeth surrounding the teeth of the inner gear and which are dimensioned to mesh with the teeth of the inner gear so that as the inner gear moves in its orbital path, the outer gear rotates one tooth for each cycle of the inner gear. The outer gear has more teeth than the inner, with the result that the outer gear rotates. The reset cam which is formed on the outer gear is angularly oriented and the speed reducing gears are so arranged to only hold the lock bar out of engagement with the ratchet teeth when the belt is near its fully wound position.

    摘要： A seat belt retractor having a rotatable reel; a clutch including a first member manipulative for blocking locking action of a pawl with a ratchet wheel on initial protraction of the belt, a land portion which permits locking action of the pawl with the ratchet wheel on partial rewind of the belt and a second member manipulative to hold the pawl away from the ratchet wheel during retraction of the belt.

    摘要： An automatic locking seatbelt retractor includes a rotatable reel biased in a belt retracting direction and having its end plates provided by circular peripherally toothed like ratchet members engageable by a rotatable spring biased pawl to block movement of the reel in an extending direction. A rotatable cam plate frictionally driven by the reel between two limit positions includes two spaced peripheral shoulders. Each shoulder is engageable with the pawl in alternate limit positions to hold the pawl out of engagement with the teeth of the ratchet members. A pivoted blocking lever is movable between blocking and unblocking positions with respect to the pawl. A pivoted control lever is linked to the blocking lever and biased to either of two positions by an overcenter torsion spring. A reel-driven ring gear includes peripherally spaced abutments engageable with the control lever. When the reel is in a fully belt-retracted position, the cam plate is in one limit position and the blocking lever is in blocking position. One of the cam plate abutments and the blocking lever engage the pawl to hold the pawl out of engagement with the teeth of the ratchet members. When the reel is rotated in a belt-extending direction and a predetermined length of belt is extended, the cam plate is frictionally driven to the other limit position and the other abutment of the cam plate engages the pawl. An abutment of the ring gear engages and then passes the control lever to move the control lever from one position to the other and in turn move the blocking member from blocking to unblocking position. Upon slight retraction and then extension of the belt after buckled to another belt to form a belt assembly, the cam plate is rotated toward the one limit position and the other abutment of the cam plate thereupon moves out of engagement with the pawl. The pawl is then spring biased into engagement with like teeth of the ratchet members and prevents further extension of the belt. As the belt is retracted, the cam plate is moved to the one limit position and the one plate abutment engages the pawl to hold it out of engagement with the ratchet members. The one abutment of the ring gear passes the control lever, and the other abutment of the ring gear engages the control lever immediately adjacent the fully retracted position of the belt to move the control lever to the one position and move the blocking lever to blocking position.
