Patent number: 6800032Abstract: A steering shaft double joint for motor vehicles includes two shaft ends each connected nonrotatably in a respective first and second joint. The first and second joints are operatively arranged in a housing to movably mount the two shaft ends. A ball joint is arranged between the first and second joints, wherein the ball joint includes a ball arranged on one of the shaft ends and a receptacle arranged on the other shaft end. The ball is arranged in the receptacle, and is rotatable around the midpoint of the ball and slidably movable in a direction of a shaft axis of the other shaft end. A plastic sliding guide is disposed between the receptacle and the ball, and a spring surrounds radially the plastic sliding guide and is disposed radially between the plastic sliding guide and the receptacle.Type: GrantFiled: June 20, 2003Date of Patent: October 5, 2004Assignee: Krupp Presta AGInventors: Gerhard Heutschi, Christian Lutz

Patent number: 6585294Abstract: A steering spindle (1) has a thin-walled container (5) which is filled by an incompressible flowable material (7). In the event of a crash, the container (5) is opened up by means of a, for example, pyrotechnic device (13). As a result, the flowable material (7) emerges and the container (5) deforms, whereby the forward vehicle intrusion is uncoupled from the behavior of the steering column.Type: GrantFiled: July 3, 2001Date of Patent: July 1, 2003Assignees: Bayerische Motoren Werke Aktiengesellschaft, Krupp Presta AGInventors: Hans-Joachim Faulstroh, Frank Schroeter, Christoph Klukowski, Elmar Moch, Matthias Renker, Matthias Hell

Patent number: 6530600Abstract: The invention relates to a steering device for motor vehicles, comprising a steering shaft that is guided by a guide box (3) which is connected to a retaining console and, for example, clamped. The console has at least one sliding surface (8) along the axis of the shaft (1) which allows for a displacement path (20) with respect to the chassis (18) in the case of a collision. Clamping means (17) are provided for axial retention of the console (6) in an initial position of said displacement path (20). Spacers (26, 27) are provided inbetween the sliding surfaces (8, 12) at a distance from the clamping means (17). When clamping occurs, said spacers cause flexural warping of the retaining device and increase the stability of the device.Type: GrantFiled: January 8, 2001Date of Patent: March 11, 2003Assignee: Krupp Presta AGInventors: Kurt Marxer, Markus Marxer, Christian Lutz
