摘要： A passive seat belt system including a movable rod connected to a seat belt and a hook member connected to the rod. The rod is driven by an electric motor actuated in response to opening and closing of a vehicle door. The rod is moved to a forward position when the door is opened, with the hook member being moved into contact with a rear portion of the belt so as to prevent interference of the belt with ingress to or egress from the vehicle. The rod is moved to a rearward position when the door is closed, with the hook member being moved out of contact with the belt.

摘要： An improved tension-relieving apparatus for a shoulder belt of a vehicle safety belt system includes: a housing, a shoulder belt support, a locking means, a force transmitting means and an actuating means. The housing has an approximately U-shape including a back wall and two sidewalls. The shoulder belt support extends between the sidewalls of the housing. The shoulder belt moves partially around the shoulder belt support as the shoulder belt is unwound from the retractor and rewound into the retractor. The locking means is disposed adjacent to the shoulder belt support. The locking means includes a clamp pivotably disposed within the housing and extending between the sidewalls of the housing. The clamp, in its locking position, prevents movement of the shoulder belt around the shoulder belt support. The force transmitting means is mounted in the housing adjacent to the locking means and moves the clamp between its locking position and its unlocking position. The clamp in its locking position removes tension on the shoulder belt produced by the rewind mechanism of the retractor. The actuating means is located in the vehicle and actuates the force transmitting means.
摘要翻译：用于车辆安全带系统的肩带的改进的张力释放装置包括：壳体，肩带支撑件，锁定装置，力传递装置和致动装置。壳体具有大致U形，包括后壁和两个侧壁。肩带支撑件在壳体的侧壁之间延伸。当肩带从牵开器解卷并重绕到牵开器中时，肩带部分地围绕肩带支撑件移动。锁定装置邻近肩带支架设置。锁定装置包括可枢转地设置在壳体内并在壳体的侧壁之间延伸的夹具。夹具处于其锁定位置，防止肩带在肩带支撑件周围运动。力传递装置安装在邻近锁定装置的壳体中，并使夹具在其锁定位置和其解锁位置之间移动。夹具处于其锁定位置可以消除由牵开器的倒带机构产生的肩带上的张力。致动装置位于车辆中并致动力传递装置。

摘要： A safety belt retractor comprises a housing containing first and second tandem spools for storing, respectively, lap and shoulder belts in helical wrap. Each of the spools is secured to a ratchet wheel engageable by a pawl located in the housing between the spools. Pawl support openings formed in opposite sidewalls of the housing enable the pawl to float while pivoting. In an equilibrium position, clearance between one end of the floating pawl and the first ratchet wheel is less than the clearance between the opposite end of the pawl and the second ratchet wheel. In response to acceleration of the vehicle carrying the retractor housing, a pendulum-type inertia device pivots the pawl from equilibrium into engagement with the first ratchet wheel. During pay out of the belts, with one end pivoting on the first ratchet wheel, the floating pawl is guided into contact with the second ratchet wheel by a cam surface defining one of the sidewall openings to positively lock the two spools. The pawl is supported by a plastic support member. The entire assembly is formed of interlocking parts.
摘要翻译：安全带卷收器包括容纳第一和第二串联卷轴的壳体，用于分别在螺旋卷绕中存放卷边和肩带。每个卷轴被固定到棘轮，棘轮可由位于壳体中的棘爪之间的棘爪啮合。形成在壳体的相对侧壁中的爪支撑孔允许棘爪在枢转时浮动。在平衡位置中，浮动棘爪的一端与第一棘轮之间的间隙小于棘爪的相对端和第二棘轮之间的间隙。响应于承载牵开器壳体的车辆的加速度，摆式惯性装置将棘爪从平衡枢转到与第一棘轮接合。在带状物的付出期间，一端在第一棘轮上枢转，浮动棘爪通过限定一个侧壁开口的凸轮表面被引导与第二棘轮接触，以正向锁定两个卷轴。棘爪由塑料支撑构件支撑。整个组件由互锁部件形成。
