Coupling member and multiple point connection

摘要

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.

1. An elastic coupling member for a three or more point connection of a vibration absorber mass, the vibration absorber mass being a gas generator for an airbag, to a motor vehicle part exposed to vibrations or oscillations, the motor vehicle part being a steering wheel structure, the coupling member comprising a sleeve-shaped spring body firmly connectable to the vibration absorber mass and the motor vehicle part and having an axial direction, wherein the spring body has a different shape in its first radial sectional plane compared to a second radial sectional plane circumferentially offset from the first radial sectional plane, wherein the spring body has an inner circumferential side and an outer circumferential side, wherein the inner circumferential side of the spring body is shaped cylindrically, wherein the outer circumferential side of the spring body is to its largest part formed by a truncated cone-shaped surface, wherein an angle of inclination of the truncated cone-shaped surface decreases in both circumferential directions around the axial direction from a maximum according to the first radial section plane, disappearing towards a cylindrical section to increase again towards the maximum.
