摘要： An actuator is adapted to selectively extend and retract a bumper member, the actuator is mounted at least partially within a tubular frame rail member of the motor vehicle. The main frame rail member may be of a standard length or of a shortened length. By mounting the actuator inside the tubular frame rail member, the bending stiffness is more effectively impacted by the outer tube of the actuator. An additional tubular frame rail member is optionally attached to the main tubular frame rail member. The actuator is mounted at least partially within the tubular frame rail member and at least partially within the additional tubular frame rail member. The wall thickness and cross-sectional shape of the additional tubular frame rail members may be adjusted to obtain a desired bending stiffness including the effect of the outer tube of the actuator.

摘要： A pre-impact mode of a bumper system is provided by extending a bumper member outwardly and extending a stiffener member downwardly. Both the bumper member and the stiffener member are separately adapted to engage an object. The bumper system includes a bumper member movable between a retracted position and a laterally extended position. A stiffener member is movable between a retracted position and a downwardly extended position. An actuator mechanism is adapted to move the bumper member between the retracted and laterally extended positions and to cause the stiffener member to move between the retracted and downwardly extended positions as a result of moving the bumper member.

摘要： If an impact occurs with an impact energy which exceeds an elastic limit of a bumper while a shock-absorbing member is in a projected position, a bumper stay is forced to move rearward along a first actuating chamber to cause the shock-absorbing member to pivot to a received position. The impact energy is primarily absorbed by an elastic force of a first spring which biases the shock-absorbing member toward the projected position. When the impact energy is not thoroughly absorbed by the first spring, the shock-absorbing member fully pivots into its received position by the bumper stay which is continuously moved rearward. At this time, a second spring which biases the shock-absorbing member forward and is prevented from being stretched forward by the shock-absorbing member, is contacted with the bumper stay via a support plate. Accordingly, the second spring secondarily absorbs the impact energy while being more compressed by the bumper stay which continuously moves rearward after causing the shock-absorbing member to fully pivot to its received position.
摘要翻译： 如果当冲击吸收构件处于突出位置时碰撞能量超过保险杠的弹性极限的冲击能力发生冲击时，缓冲器撑杆被迫沿第一致动腔向后移动，以使缓冲构件枢转 到接收的位置。 冲击能量主要被第一弹簧的弹力吸收，该第一弹簧将冲击吸收构件偏压到突出位置。 当冲击能量不被第一弹簧充分吸收时，减震构件通过连续向后移动的保险杠撑杆完全枢转到其接收位置。 此时，使缓冲构件向前方偏置并被防震构件向前方拉伸的第二弹簧经由支撑板与保险杠座抵接。 因此，第二弹簧二次吸收冲击能量，同时在使缓冲构件完全枢转到其接收位置之后，通过保持架支撑而连续地向后移动而被更大的压缩。
