The present disclosure relates to an apparatus that has a conduit and an impact absorber assembly. The impact absorber assembly includes a core and a frame, where the core has an aperture configured to receive the conduit and the frame includes a cavity sized and shaped to receive the core. The frame also has a first side wall and a second side wall that are spaced apart to define, at least in part, a cavity. The first and second side walls also include an intermediate portion that includes a waveform shape. The waveform shape includes at least a pair of ridges and a trough between the ridges.

A dampener assembly dampens vibrations between a first member and a second member. The bumper comprises a cellular material defining a plurality of cells. The bumper has a mounting surface wherein a portion of the plurality of cells are open at the mounting surface. The dampener assembly also includes an overmolded bracket comprising a polymeric material. The overmolded bracket has a body portion extending between a first bracket end and a second bracket end. The body portion has an attachment surface configured to couple to the first member. The body portion also has a bonding surface opposite the attachment surface with the bonding surface coupled to the bumper. The polymeric material of the overmolded bracket is disposed within the open cells at the mounting surface of the bumper for bonding the overmolded bracket and the bumper to one another.

The invention concerns a suspension thrust bearing for use with a suspension spring in an automotive suspension strut. The suspension thrust bearing provides a bearing with an annular upper part and a annular lower part in relative rotation one to the other, a lower support surface being provided by the lower part that axially supports an upper end of a suspension spring by the intermediate of a damping device made from resilient material. The resilient material of the damping device is molten in its preformed state with gas. After being molded, the molten material of the damping device provides an outer skinny layer and an inner foam body, the density of the outer skinny layer being strictly greater than the density of the inner foam body.

A spacer (1) for vibration-damped fastening of a mounting part (2) to a carrier part (3), wherein the spacer has a base body (4) with a first flange region (5) and a second flange region (6) which is opposite viewed in the longitudinal direction (L) of the base body and with a passage (7) in which a fastener (8) which is connected to the carrier part, can be received at least sectionally. The base body has an at least two-part design with a first body part (9) and at least a further, second body part (10), wherein the body parts can be detachable connected to one another to create the base body and wherein, in the connected state, a gap region (11) is provided between the first and second flange region, by which the border of a fastening hole (18) configured in the mounting part can be received.

To provide a vibration control bush that ensures improved durability of a rubber elastic body. An inner pipe film portion of the vibration control has an inclined surface whose inclination angle θ with respect to an axis O direction is set to one degree or more and less than three degrees, and the inner pipe film portion has an end portion in the axis O direction whose thickness dimension is set to a quarter or less of a dimension in an axis O perpendicular direction from an outer peripheral surface of an inner pipe to an apex of the protruding portion. This ensures reducing a rubber elastic body to deform so as to bend (close contact) between the inner pipe film portion and the outer pipe film portion when a load in a wrenching direction is input. Accordingly, a durability of the rubber elastic body can be improved.
