    • A windshield wiper assembly provides variable contact pressure between the wiper blade and the windshield by utilization of a lever arm variably movable within a cam slot as the windshield wiper reciprocates across the windshield. A spring provides a bias force between the wiper arm and the lever arm of the assembly. The spring force acts through a moment arm to urge the wiper blade into contact with the windshield. The magnitude of the moment arm through which the spring bias force acts to urge the wiper blade into contact with the windshield is adjusted in accordance with the position of the wiper blade on the windshield as a result of the predetermined configuration of the cam slot which acts on the lever arm to which one end of the spring is attached. In this manner, the contact pressure between the wiper blade and the windshield is reduced at the extreme ends of the windshield wiper throw so as to reduce the noise typically associated with the windshield wiper reversing direction on the windshield.
    • 挡风玻璃刮水器组件通过利用当挡风玻璃刮水器往复运动穿过挡风玻璃时可在凸轮槽内可变地移动的杠杆臂来在刮片和挡风玻璃之间提供可变的接触压力。 弹簧在组件的刮水器臂和杠杆臂之间提供偏压力。 弹簧力通过力臂作用,以促使刮水片与挡风玻璃接触。 根据作用于凸轮槽的预定构造的结果,根据刮水片在挡风玻璃上的位置来调节弹簧偏置力作用以推动刮水片与挡风玻璃接触的力臂的大小, 在连接弹簧的一端的杠杆臂上。 以这种方式,刮水器叶片和挡风玻璃之间的接触压力在挡风玻璃刮水器突出部的最末端被减小,以便减少通常与挡风玻璃刮水器反向方向相关联的噪音。

    • A windshield wiper includes a first pin connected to a drive mechanism, a primary lever supported by the first pin, a second pin mounted to the primary pin, a wiper arm fixedly mounted to the second pin, the primary lever being rotated about the second pin by the drive mechanism to cause reciprocating motion of the wiper arm in an arcuate path, a first cam member rotatable about the first pin, a second cam member rotatable about the second pin, and a secondary lever for connecting the first cam member and the second cam member together. The second cam member is so rotated as to allow a center of the first cam member to move relative to a center of the first pin, thereby changing the effective length of the primary lever such that the arcuate path of the wiper arm is changed. A wheel gear is used to rotate the second cam member through a predetermined angle. The second cam member is rotatably supported by a stationary member. A gear portion is meshed with the wheel gear and rotated by the motor. The wheel gear and the gear portion are both housed in a casing which is, in turn, fixed to the stationary member.
    • 挡风玻璃刮水器包括连接到驱动机构的第一销,由第一销支撑的主杆,安装到主销的第二销,固定地安装到第二销的刮水器臂,主杆围绕第二销旋转 通过所述驱动机构使得所述刮水器臂在弓形路径中的往复运动,可围绕所述第一销旋转的第一凸轮构件,可围绕所述第二销旋转的第二凸轮构件,以及用于将所述第一凸轮构件和所述第二凸轮 凸轮成员在一起 第二凸轮构件被旋转以允许第一凸轮构件的中心相对于第一销的中心移动,从而改变主杆的有效长度,使得刮水臂的弧形路径改变。 使用轮齿轮使第二凸轮构件旋转预定角度。 第二凸轮构件由固定构件可旋转地支撑。 齿轮部分与齿轮啮合并由马达旋转。 轮齿轮和齿轮部分都被容纳在壳体中,壳体又固定到固定构件。

    • A vehicle door opening-closing device which enables a reduction in the time for releasing a fully closed condition of the vehicle door without changing the driving force and the driving speed of the actuator when operating a vehicle door from a half closed condition to the fully closed condition and when releasing the fully closed condition. A latch mechanism includes a latch engageable with a striker and an engagement member for maintaining the latch at a condition for operating the vehicle door to the half closed condition and the fully closed condition. An operation mechanism operated by a motor operates the latch by way of a closing lever and operates the engagement member by way of an opening lever based on operation of an operation member. The opening lever possess a smaller lever ratio than the lever ratio of the closing lever.
    • 一种车门打开关闭装置,其能够在将车辆门从半关闭状态操作到完全关闭的同时减少用于释放车门的完全关闭状态的时间而不改变致动器的驱动力和驱动速度 当释放完全关闭状态时。 闩锁机构包括可与撞针接合的闩锁和用于将闩锁保持在用于将车门操作到半闭合状态和完全关闭状态的状态的接合构件。 由电动机操作的操作机构通过关闭杆操作闩锁,并且通过基于操作构件的操作的开启杆操作接合构件。 开启杆具有比关闭杆的杠杆比小的杠杆比。
