Abstract (en)
[origin: WO0016999A1] An air plunger (11) to be used in an air cushioning device in a vehicle has the shape of a straight, circular cylinder, which is closed at one end by means of a first end wall (12) and which at the other end has a second end wall (13) with a centre opening (14). The air plunger (11) has an inner supporting element (16) with a first portion (17), which has the shape of a hollow, truncated, straight, circular cone. The smaller end of the truncated cone abuts against the first end wall (12), and the outer diameter of the larger cone end is essentially equal to the inner diameter of the cylinder. The inner supporting element (16) is connected to the cylinder to provide transfer of forces from the jacket of the cylinder to a centre area, defined by the smaller cone surface, of the first end wall (12).
