摘要： A pretensioner (40) is connected with a seat belt buckle (32) and is operable to move the buckle through a pretensioning stroke to remove slack from a seat belt. Movement of an actuator member (36) from an unactuated position to an actuated position under the influence of its own inertia at the end of a pretensioning stroke is resisted by a pair of counterbalance assemblies (162, 164) disposed in the buckle (32). The counterbalance assemblies (162, 164) include masses (168, 176) having inertia which results in the application of force against counterbalance cams (212, 232) connected with the actuator member (36). This force resists movement of the actuator member (36) to an actuated position at the end of the pretensioning stroke. Upon the application of manual force against an outer end portion of the actuator member (36) to release the buckle, the masses (168, 176) are pivoted by the counterbalance cams (232, 212). Cam followers (196) connected with the masses then slide along longitudinally extending side surfaces (216, 240) of the counterbalance cams (212, 232). The counterbalance masses (168, 176) are mounted between elongated sections (132, 134, 148 and 150) of the actuator member (36).
摘要翻译：预紧器（40）与安全带扣（32）连接，并且可操作以使带扣通过预张紧行程移动以从安全带去除松弛。致动器构件（36）在预紧力行程结束时在其自身惯性的影响下从未致动位置到致动位置的移动被设置在带扣（32）中的一对平衡组件（162,164）抵抗，。平衡组件（162,164）包括具有惯性的质量块（168,176），其导致对与致动器构件（36）连接的平衡凸轮（212,232）施加力。该力抵抗致动器构件（36）在预张紧行程结束时的致动位置的运动。当对致动器构件（36）的外端部施加手动力以释放带扣时，质量块（168,176）由平衡凸轮（232,212）枢转。与质量块连接的凸轮随动件（196）然后沿平衡凸轮（212,232）的纵向延伸的侧表面216,240滑动。平衡块（168,176）安装在致动器构件（36）的细长部分（132,134,148和150）之间。

摘要： A slider bar for use with two-door style motor vehicles for anchoring the lap belt for front seat occupants. The slider bar allows the lower anchorage point of the lap belt to freely move in the fore and aft direction to enhance rear seat compartment passenger ingress and egress. The slider bar further incorporates a pyrotechnic lap pretensioner (PLP) function for exerting pretensioning motion of the lap belt in response to a vehicle impact. The slider bar incorporates an internal piston which acts on the belt webbing position on the outside of the slider bar tube. Various embodiments are described incorporating alternate means of mounting the lap belt lower end to the slider bar, as well as various configurations for transferring the motion of the internal piston to the lap belt lower anchorage.

摘要： A linear seat belt pretensioner (10, 110, 210) has a frame (12; 112, 113; 212, 213) and an axial cavity (24, 60; 124, 160; 232) rigidly connected to the frame (12; 112, 113; 212, 213), a gas generator (20, 120, 220) in fluid communication with the axial cavity (24, 60; 124, 160, 232), and a piston (40, 140, 240) movably arranged in the axial cavity (24, 60; 124, 160; 232). An actuating profile (42, 142, 242) movable with the piston (40, 140) pulls a length of seat belt webbing (38, 238) into the frame (12; 112, 113; 212, 213) that corresponds to twice the piston stroke (D). The pretensioner device having a locking ramp arrangement (66, 70; 266, 290, 292) configured to form a one-way clutch allowing an increase and resisting a reduction of the length of belt webbing (38, 238) received by the pretensioner (10, 110, 210).

摘要： A seat belt buckle (16) for use with a seat belt pretensioner (30) has an inertia locking mechanism (52). A latch member (64) in the buckle (16) has a locking position for engaging a seat belt locking tongue (14) to block removal of the tongue (14) from the buckle (16). A pushbutton (22) moves the latch member (64) out of the locking position against a bias of a spring (70). The inertia locking mechanism (52) includes a blocking structure (82) which moves into blocking contact with the latch member (64) in response to a predetermined amount of deceleration which occurs when the buckle (16) decelerates and stops moving under the influence of the pretensioner (30).
