The buckle additionally includes a latch plate (,), having portions (,) movable within the latch plate slots between a locked position in engagement with an opening within the tongue and with the first latch opening (,), the latch plate moveable between a latched position within the latch opening (,) in the frame and within the latch opening (,) of the tongue to an unlatched position out of the latch openings. The weight (,) as it pivots generates a force upon the latch plate during operation of the pretensioner tending to keep the latch plate in the first opening and a button (,) operatively received upon the frame having ramp means (,) for lifting the latch plate to its unlatched position.

Buckle for use with a pretensioner

A seat belt buckle (100) operable with a pretensioner (330) comprising: a frame (102) having a first latch opening (126a) therein, and opposing frame sides (108a,b), each side including a latch plate slot (110) arranged generally perpendicular to the direction of movement of a tongue into the buckle and pivoted weight mechanism (112, 200, 220). The buckle additionally includes a latch plate (180), having portions (186) movable within the latch plate slots between a locked position in engagement with an opening within the tongue and with the first latch opening (126a), the latch plate moveable between a latched position within the latch opening (126a) in the frame and within the latch opening (173) of the tongue to an unlatched position out of the latch openings. The weight (200) as it pivots generates a force upon the latch plate during operation of the pretensioner tending to keep the latch plate in the first opening and a button (250) operatively received upon the frame having ramp means (260) for lifting the latch plate to its unlatched position.

A pretensioning apparatus for a vehicular safety restraint, which includes a housing; a tube extending from the housing and defining an inner surface; a piston disposed within the tube in close proximity to the inner surface of the tube; a linkage connected at a first end to the piston and having a second end which is adapted for connection to a safety restraint; and a lock member having at least a portion thereof disposed between the piston and the inner surface of the tube, the lock member being configured and dimensioned such that upon application of a force to the piston in a first direction, the lock member permits free movement of the piston in the first direction and upon application of a force to the piston in a second direction being reverse to the first direction, the lock member biases against the inner wall of the tube to prevent movement of the piston in the second direction.

Apparatus for pretensioning a vehicular seat belt

An apparatus (20, 400) comprising: first driven gear (402) operatively linked a spool of a retractor (20) to rotate the spool (24) in a direction of retraction to cause a seat belt (31) wound thereabout to retract; flexible first driving member (430, 432) having a front end (435) initially maintained out of engagement with the driven gear and pushed into engagement with the first driving member to cause same to rotate; second driving member (420) operatively linked to a rear end of the first driving member for pushing the first driving member into engagement with the driven gear thereby causing the driven gear to rotate.

Chain driven pretensioner and retractor

A seat belt buckle (100) comprising: a frame (102) having a tongue receiving opening (170) to receive a tongue (173) as the tongue is moved in a first direction, a latch member (180) arranged to move from a latched position to an unlatched position, an ejector to eject the tongue which the latch member is in its unlatched position, an electronic sensor assembly (400) located upon the frame (102) comprising a magnetic sensor and a spaced magnet, a metal bar (260) supported on one of the latch member (180), the ejector (131) or a pivot member (500) and movable into position between the sensor and the magnet.

Seat belt buckle

An energy absorbing seat belt retractor comprises a frame, a spool rotatably mounted relative to the frame for protracting and retracting a seat belt wound thereabout, and a driving member (e.g., a rotatable and slidable nut) operatively coupled to the spool. A deformable energy absorbing member is disposed within a bore of the spool and functions to receive a driving force supplied by the driving member responsive to an occupant load, and to deform when the driving force exceeds a predetermined threshold to thereby absorb energy and permit a controlled rotation of the spool and a corresponding controlled protraction of the belt as the belt is loaded by the occupant. At least one stop ring is disposed in proximity to the deformable member and functions to contact the deformable member in a deformed state and control further deformation thereof to thereby limit the protraction of the seat belt.

Retractor with load limiting spool

An energy absorbing seat belt retractor (10) for controlling protraction of seat belt webbing (24) during a collision is provided. The seat belt retractor (10) includes a frame (12), a spool (20) rotatably supported on the frame (12) having webbing (24) wound thereabout, a bifurcated spool shaft (22) having a first portion (52) and a second independently rotatable portion (54), a locking mechanism (90, 91) associated with each portion of the spool shaft (22), and a load limiting mechanism (41, 43) interconnecting each shaft portion to the spool (20). The locking mechanisms (90, 91) are independently and simultaneously actuable by vehicle sensors (86, 87) to selectively engage and prevent rotation of either one or both of the first and second shaft portions (52, 54) to initiate operation of either one or both of the load limiting mechanisms (41, 43) to effectively control the threshold input force level required to permit controlled protraction of the seat belt webbing (24).

Dual level retractor for oblique or offset impacts

An apparatus (20, 500) comprising: first driven gear (502) operatively linked to a spool of a retractor (20) to rotate the spool (24) in a direction of retraction to cause a seat belt (31) wound thereabout to retract; a helically shaped first driving member (530) having a front end (536) initially maintained out of engagement with the driven gear and pushed into engagement with the first driving member to cause same to rotate; second driving member (520) operatively linked to a rear end of the first driving member for pushing the first driving member into engagement with the driven gear thereby causing the driven gear to rotate.
