Abstract: A damper system for damping vibrations of an assembly unit of a vehicle comprises one or more main vibration dampers and one or more acoustic bushings. The respective main vibration damper is tuned to vibrations from a lower frequency range. The respective acoustic bushing is tuned to vibrations from a higher frequency range which lies above and does not overlap with the lower frequency range.

Abstract: A vibration absorber for absorbing a vibration of a vibrating component is provided and includes: a spring system and an absorber mass arranged on the spring system. The spring system includes: a first spring element with a first core, and a second spring element with a second core. The first spring element is arranged on the second spring element such that the second core borders the first core, and the vibration absorber can be fastened using a fixing element to the vibrating component in which the vibration is to be absorbed. Furthermore, a method of producing the vibration absorber is further provided.

Abstract: An oscillation damper is provided and includes: a holder for mounting the oscillation damper on an object to be damped; a damping mass; and a coupling device designed to mount the damping mass on the holder. The coupling device includes: a damping mass mounting element rigidly connectable to the damping mass; a holder mounting element rigidly connectable to the holder; and a spring element resiliently mechanically coupling the damping mass mounting element to the holder mounting element. A method for manufacturing an oscillation damper is further provided.

Abstract: A vibration absorber (1) with radially acting hydraulic damping has a bearing core (2). A bearing cage (4) radially surrounding the bearing core (2) and an elastomer body (18) resiliently connects the bearing core (2) and the bearing cage (4). An outer sleeve (24) radially surrounds the elastomer body (18) for connection to an absorber mass (40). At least two working chambers (28) to be filled with a damping fluid are formed in the elastomer body (18). The working chambers (28) are connected fluidically to one another by means of a dimensionally stable fluid duct (26).

Abstract: For an elastic coupling member for a three (or more) point connection of a vibration absorber mass, like a gas generator for an airbag, to a motor vehicle part exposed to vibrations or oscillations, like a steering wheel structure, comprising a sleeve-shaped spring body firmly connectable to the vibration absorber mass and the motor vehicle part and having an axial direction, it is provided that the spring body has a different shape in its first radial sectional plane, in particular a vertical radial sectional plane, compared to a second, in particular horizontal radial section plane circumferentially offset from the first one.

Abstract: An elastic coupling device for elastically connecting a damping mass like a gas generator to a motor vehicle part exposed to oscillations and/or vibrations, in particular an airbag module, in one embodiment comprising a rigid support ring facing the vehicle, at least one fixation piece like a rivet head, the fixation piece facing the damping mass and being made of a rigid material, and a spring body coupling the support ring and the fixation piece. The support ring and/or the fixation piece, respectively made of a plastic material, as well as the spring body, which may be made of an elastomer material, may be produced in a single manufacturing step by means of a two-component process, in particular by two-component injection molding.
