摘要： In a vehicle seat assembly having a backrest member pivotally movable with respect to a seat member, there is disclosed a device for controlled adjustment of the inclination of the backrest member with respect to the seat member, which device includes a redundant locking mechanism which is activated upon failure of the primary locking mechanism so as to prevent uncontrolled rearward pivoting of the backrest member over the seat member. Moreover, the activation of the secondary locking structure is signalled to the seat occupant by a change in the operation of the device, which change in operation prevents the seat occupant from attempting to re-adjust the inclination of the backrest member without servicing of the device by qualified personnel.

摘要： This invention provides an improved adjustable latching device for use with a vehicle seat assembly having a first and a second seat member pivotally foldable relative to one another about a pivot axis between folded and unfolded operative configurations. The device accommodates both the well-known "dumping" and "reclining" features and is comprised of a latch pin rigidly mounted on the first seat member so as to define a first concentric arc of movement upon said pivotal folding of the first seat member about the pivot axis and an idler plate having a generally arcuate gear sector and being mounted for rotation about the pivot axis. A locking arm is rotatably mounted on the idler plate and presents a detent portion position adjacent one end in spaced relation from the point of rotational movement of the arm so as to be adapted to lockingly engage the latch pin, which locking engagement in turn causes rotation of the idler plate with the first seat member in at least one rotational direction upon pivotal folding of the first seat member. A first rotational control means for selectively rotating the locking arm into and out of the aforementioned locking engagement is also provided. A pawl means having a head and a tail portion is pivotally mounted on the second seat member intermediate its head and tail portions for pivotal movement between a first rotational position at which the head portion lockingly engages the gear sector to prevent rotation of the idler plate and the second rotational position at which the head portion is disengaged from the gear sector to allow for rotation of the idler plate about the pivot axis. A second rotational control means for selectively rotating the pawl means between the aforementioned first and second rotational positions is also provided. The device disclosed is considerably simpler to manufacture and assemble than previously known devices having the same features.

摘要： A seatback latching mechanism for use in a vehicle seat assembly having a backrest member pivotally tiltable over a seat member. The mechanism has a first latch means fixed relative to the seat member and a second latch means pivotally mounted on the backrest member for pivotal movement thereof between an unlatched and a latched position in which tilting movement of the backrest member over the seat member is restrained. Pendulum means are pivotally mounted on the backrest member for pivotal movement independently of the pivotal movement of the second latch means between first and second pendulum limit positions at which limit positions the pendulum means impinges upon the second latch means.In the normal upright position of the backrest member, the pendulum means is gravity biased to the first limit position in which the composite center of gravity of the pendulum means and the second latch means is positioned eccentrically of the pivot axis thereby urging the second latch means towards the unlatched position. Upon the occurrence of a first vehicular deceleration force sufficient to overcome the gravity biasing of the pendulum means to the first limit position, the pendulum means pivotally moves to the second pendulum limit position thereby increasing the sensitivity of the mechanism to latching, such that, upon the attainment of a second greater vehicular deceleration force, the second latch means moves rapidly to the latched position thereof.
摘要翻译：一种用于车辆座椅组件的座椅靠背闩锁机构，其具有可枢转地在座椅构件上倾斜的靠背构件。该机构具有相对于座椅构件固定的第一闩锁装置和枢转地安装在靠背构件上的第二闩锁装置，用于在解锁位置和闩锁位置之间枢转运动，在该位置中，靠背构件在座椅构件上的倾斜运动被限制。摆臂装置可枢转地安装在靠背构件上用于枢转运动，而与第二锁定装置在第一和第二摆位置极限位置之间的枢转运动无关，摆动装置将摆锤装置撞击在第二闩锁装置上的极限位置。在靠背构件的正常直立位置，摆锤装置被重力偏压到第一极限位置，在第一极限位置，摆锤装置的复合重心与第二闩锁装置偏心于枢转轴线，从而推动第二闩锁装置朝向未锁定的位置。在发生足以克服摆锤装置的重力偏压到第一极限位置的第一车辆减速力时，摆锤装置枢转地移动到第二摆极限位置，从而增加机构锁定的灵敏度，使得在达到第二较大的车辆减速力，第二闩锁装置快速移动到其锁定位置。
