Abstract: This type of rollover protection system typically comprises a roll bar body that is either firmly anchored to the vehicle, or is displaceably guided in a guide element that is fixed to the vehicle, in conjunction with a locking device that serves as a retraction blocking mechanism to lock the deployed roll bar body against any unintended retraction. To structurally control high peak loads that occur in a rollover without a total failure of the protective system, particularly of the locking device in deployable systems, the invention provides that the roll bar body, possibly the associated guide element and its fixation on the vehicle as well as the retraction blocking mechanism be configured as a rigid system relative to the maximum load that occurs in a rollover. A cross-member-type support element terminating the roll bar body on the end face is configured as a predetermined deformation point for a limited defined deformation path in load direction for energy degradation.

In order to ensure small assembly dimensions while at the same time offering a low-cost connection method, the invention provides a connection of the guide block (11) to the U-shaped lateral parts (8, 9) in the shape of a form-fit connection (8a, 11a).

Abstract: A birdcage assembly for a high performance vehicle includes a birdcage having an opening defined by an inner periphery. The birdcage is secured to a rear suspension of the vehicle and is maintained in a substantially vertical position. The opening is intended to receive a vehicle axle therethough. The opening has a bearing located therein, which includes an inner race, an outer race, and a plurality of rollers disposed between the inner race and the outer race. The inner race of the bearing is in communication and rotates with the vehicle rear axle. Further, the bearing is moveable with respect to the birdcage such that as the axle deviates from an orientation parallel to ground, the bearing can move with respect to the birdcage away from a vertical position. The floating aspect of the bearing with respect to the birdcage minimizes side loads on the birdcage are thus prolongs the life of the bearing.

Abstract: A method for activating a passenger safety application in a vehicle involves a rotational acceleration sensor device which is used to obtain a measurement of the rotational acceleration &agr;x of the vehicle, e.g., about an axis of rotation x parallel to the longitudinal axis of the vehicle.
