A seat belt webbing guide height adjuster (10) includes a base (50) having a column (80) of openings (84, 86, 88) spaced along an axis (61). A carriage (120) is supported on the base (50) for movement along the axis (61) relative to the base. A seat belt webbing guide (24) is supported on the carriage (120). First and second latch parts (160, 180) on the carriage (120) are independently movable between a first condition not located in any one of the openings (84-88) and a second condition located in one of the openings to block axial movement of the carriage relative to the base (50). The first and second latch parts (160, 180) are configured and disposed on the carriage (120) so as to be capable of locating in the same opening (84-88) simultaneously. The height adjuster (10) also includes biasing means (210) for biasing the first and second latch parts (160, 180) into the second condition, and actuatable release means (200) for moving the first and second latch parts to the first condition. The first and second latch parts (160, 180) are movable from the second condition into the first condition in response to upward movement of the carriage (120) relative to the base (50) when the release means (200) is unactuated.

A buckle assembly (36) includes a latch member (50) which is movable between an engaged position and a release position. A pushbutton (88) is manually actuatable from a first position to a second position to move the latch member from the engaged position to the release position. The latch member is movable from the engaged position to the release position against force provided by only a latch spring (64) upon insertion of a tongue (38, 40) into the buckle assembly. The pushbutton is manually actuatable from the first position to the second position against a combined force provided by the latch spring and a coil spring (92). A one-piece plastic locator member (112) is mounted on a base (44) of the buckle assembly. The locator member extends into a belt receiving opening (46) in the base to protect the belt (32) against abrasion by the metal base. The locator member has a first recess (118) which receives an end portion of the coil spring and a second recess (122) which receives an end portion ( 82) of the latch spring. The coil spring extends from the recess in the locator member, through an opening (95) in the latch member, into engagement with the pushbutton.

A locking tongue has a base part, a webbing slot in the base part and a locking cam. The locking cam is movable between a rest position and a clamping position. A biasing means biases the locking cam towards the rest position. The locking cam can assume the rest position in which the belt webbing can pass freely through the webbing slot, a clamping position in which the locking cam presses the belt webbing against the clamping edge of the webbing slot, the biasing means being able to return the locking cam from the clamping position into the rest position, and a locking position in which the locking cam locks the belt webbing in the webbing slot, the biasing means not being able to return the locking cam from the locking position towards the rest position.

A head restraint (14) for helping to protect an occupant (60) of a vehicle seat (20) includes a base frame (150) connected to the vehicle seat. A cushion carrier (350) is supported on the base frame (150) by a track assembly (440) that facilitates movement of the cushion carrier (350) relative to the base frame (150) along a deployment axis (18) from a non-deployed condition to a deployed condition. The track assembly (440) includes a fixed track member (182) that forms a portion of the base frame (150). The fixed track member (182) includes spaced axially extending beam portions (190) with opposing surfaces (200) that define a channel (184) between the beam portions (190). The track assembly (440) also includes a sliding track member (370) that forms a portion of the cushion carrier (350). The sliding track member (370) includes a sliding frame (372) positioned in the channel (184) and having portions (442) positioned in sliding contact with portions (444) on the opposing surfaces (200) defining the channel (184).

A seat belt system (10) for restraining a vehicle occupant includes a retractor (18), a first locking tongue (40), a second locking tongue (46) and a buckle (20). The retractor (18) includes a spool (60) which is rotatable in a webbing winding direction and a webbing unwinding direction. The retractor (18) further includes a lock bar (70) which blocks rotation of the spool (60) in the webbing unwinding direction when the lock bar (70) is in a locking position. The first locking tongue (40) is connected with one length (26) of seat belt webbing (16). The second locking tongue (46) is connected with another length (28) of seat belt webbing (16). The buckle (20) has a locking mechanism (82, 90) for locking the first and second tongues (40) and (46) in a buckle (20). The seat belt system (10) further includes an actuator (130) for moving the lock bar (70 ) in the retractor (20) into the locking position in response to locking of the first and second tongues (40) and (46) in the buckle (20). The actuator (130) moves the lock bar (70) into the locking position only in response to locking of both the first and second tongues (40) and (46) in the buckle.

A tongue assembly (10) is movable along seat belt webbing (16) and includes a latch plate sub-assembly (74) for engaging a buckle (26). A cinch bar (130) is carried by the latch plate sub-assembly (74) for pivotal movement relative to the latch plate sub-assembly between a disengaged position enabling the seat belt webbing and the latch plate sub-assembly to move relative to one another and an engaged position clamping the seat belt webbing against the latch plate sub-assembly. A method of assembling the tongue assembly (10) comprises the step of inserting a first end (138) of the cinch bar (130) into a first opening (128) in the latch plate sub-assembly (74) by movement of the cinch bar in a first direction (C). A second end (139) of the cinch bar (130) is inserted into a second opening (129) spaced away from the first opening (128) in the latch plate sub-assembly (74) by movement of the cinch bar in a second direction (E) opposite the first direction (C). The first end (138) of the cinch bar (130) is maintained in the first opening (128) while the second end (139) of the cinch bar is inserted in the second opening (129).
摘要:
A buckle for receiving a locking tongue connected to a seat belt has a passage into which the tongue is movable and a locking member movable in the passage. The locking member is movable into and out of locking engagement with the tongue when the tongue is received in the passage. The buckle also has an unlocking member and a lever arm. The unlocking member is movable relative to the locking member, and moves the locking member out of engagement with the tongue when the unlocking member is moving relative to the locking member. The lever are has a handle portion and a cam surface. The cam surface is pivotally movable in sliding contact with the unlocking member to move the unlocking member relative to the locking member upon pivotal movement of the handle portion in a first direction away from the passage.
