  • Patent number: 10934758
    Abstract: An adjustable bumper assembly includes a bumper assembly insert having a bumper head, a threaded portion connected to the bumper head and a ratchet portion extending from the threaded portion. A coupling ring is threadably connected to the threaded portion. The coupling ring has a ratchet device with a tooth biased into contact with the ratchet portion. A base member includes multiple retention arms homogeneously connected to the base member extending away from a face of the base member. The coupling ring when slidably received in a through passage created in the face of the base member contacts the retention arms. The coupling ring is non-rotatably engaged to the base member such that axial rotation of the bumper assembly insert with respect to the coupling ring axially extends or retracts the bumper assembly insert with respect to the base member.

  • Patent number: 7296766
    Abstract: A structural damping assembly includes a bonding plate, a stiffener layer, an elastomeric layer, and a constraining layer. The elastomeric layer is boned between the stiffener layer and the constraining layer. The bonding plate and the stiffener layer extend between, and are preferably in contact with, webs which form a pocket on a substrate such as a transmission support beam. The structural damping assembly uses the energy dissipating properties of the elastomeric layer that is sandwiched between the vibrating stiffener layer and the constraining layer to combat noise due to resonant response while operating as a stiffener that increases the frequency of resonance to a range where coincidental placement with an excitation frequency is reduced.

  • Patent number: 5735511
    Abstract: The present invention relates to a self-adjusting stopper for dampening movable parts, in particular for lids, hoods or the like in automotive vehicles, and comprises a stop element, a casing, a clamping element and a coupling element in cooperative relationship. Initially the stop element projects a maximum distance out of the casing. By closing the part which has to be dampened, for example the hood of an automotive vehicle, the stop element becomes displaced into the casing. After opening the lid, the clamping element is locked to the stop element by rotating the coupling element to axially adjust the stop element within the casing. A further adjustment is not required. According to the invention, the stop element will be automatically adjusted in a proper axial position by just closing and opening the lid.

  • Patent number: 4371141
    Abstract: A vibration isolation system includes a seismic restraint assembly that attenuates forces above a chosen magnitude transmitted to a unit from a support during a seismic event. Vertical friction elements on a vertical frame engage and support a vertical damper element. Horizontal friction elements on a horizontal frame engage and retain a horizontal damper element. One frame is connected to the unit, the other to the support. The vertical and horizontal damper elements interconnect, but lost motion spacing between these elements ordinarily prevents low level vibrations being communicated therethrough. Each of the vertical and horizontal friction elements is spring biased into a predetermined frictional engagement with its associated damper element. The force of the engagement is adjustable to adjust the level at which higher than ordinary forces that are being transmitted through the assembly will begin to be attenuated by slippage of the frictionally engaged elements.

  • Patent number: 4266630
    Abstract: In a forward engine compartment of a vehicle a power unit is suspended so as to have a controlled rearward movement in the engine compartment when exposed to excessive forces in the lengthwise direction of the vehicle during a collision. There is at least one rear mounting having a resilient body separating two members secured to the power unit and to structural portions of the vehicle body, respectively. Said rear mounting allows one of the members a limited movement relative to the other while absorbing deformation work. As the power unit travels further back the attachment of the rear mounting is gradually destroyed, but it holds long enough to allow the power unit to hit a cowl panel at the rear of the engine compartment, thus controlling the travel of the power unit.

Resiliently displaceable energy absorbing means are positioned on either side of the head portion to resist displacement in either the fore or aft direction. The head is dimensioned to prevent removal from the containment housing and is surrounded by a rubber-like member, which resiliently resists displacement in combination with compression springs. The rubber member also resists displacement in directions transversed to the permitted fore and aft displacment. The resilient spring force applied to the head of the mounting element can be adjusted to vary the energy absorption characteristics of the motor mount assembly.
