  • Publication number: 20240117825
    Abstract: An assembly for a fluid-filled piston-cylinder unit comprises a main body having an assembly longitudinal axis (24), a valve unit integrated in the main body and having an overflow channel, which valve unit seals the overflow channel when the assembly is moved along the assembly longitudinal axis in a first direction and releases the overflow channel, in dependence on the fluid pressure, when the assembly is moved along the assembly longitudinal axis in a second direction. Furthermore, the assembly comprises an outer seal element that is arranged on the main body so as to be moved along the assembly longitudinal axis, for abutting in a sealing manner against an inner surface of the housing, and at least one undercut element formed on the main body for engaging in an interlocking manner behind a mating element of the piston-cylinder unit.

  • Patent number: 9309943
    Abstract: A pendulum support is particularly suited for supporting an engine unit. The support has two mutually spaced-apart fixing elements for connecting two bodies that can be displaced in relation to one another. The fixing elements are elastically interconnected. The object is to provide a pendulum support with a high degree of deflection that is cost-effective to produce. The base body has two base body elements, which are interconnected by at least one elastic shear element. At least one of the base body elements is formed with a cavity, wherein one area of the other base body element is contained with a degree of deflection.

  • Patent number: 8398174
    Abstract: A seat cushion has a plurality of foamed-in fastening elements, in particular for utilization in vehicle seats, wherein the fastening element is formed by a flat retainer element having a fastening web connected thereto and serving as a counter-retainer. The retainer element is foamed into the foam body of the seat cushion, wherein the counter-retainer is not covered by the foam body of the seat cushion. A stitching wire fastened at the cushion cover can thus be connected to the counter-retainer in a load-transmitting manner.

  • Patent number: 8348250
    Abstract: A pneumatically damping mount, in particular an engine mount for motor vehicles, includes a bearing spring of elastomeric material for supporting a mount core and delimiting a working chamber. The working chamber is filled with a gas, in particular air, and communicates with the ambient atmosphere through a nozzle opening. A progression element of elastomeric material is disposed opposite the bearing spring and delimits the working chamber together with the bearing spring, to enable further deformation of the mount after closing of the working chamber.

  • Patent number: 8342607
    Abstract: A seat cushion for the production of a vehicle seat has a foam body and a carrier element. The carrier element is disposed on the back side of the foam body and provides mechanical support to the foam body on the back side thereof. At least one bubble element is disposed between the foam body and the carrier element and can be supplied with compressed air via an air inlet. The carrier element features an air-impermeable barrier layer on the side facing towards the foam body. The bubble element is composed of two bubble halves that are connected to one another by means of an airtight sealing joint, and wherein the bubble half facing away from the foam body is formed by a surface section of the barrier layer of the carrier element, and wherein the second bubble half facing towards the foam body is fastened at the assigned surface section of the barrier layer while forming the airtight sealing joint.
