A support element for positioning a first element, in particular a cover, on a second element, in particular a housing, includes an annular disk-shaped base body that can be positioned on a support rod fastened on the second element, the base body having on a first end face a support surface for making supporting contact with the first element, where the support element has, on the first end face, a plastically deformable projection forming the support surface.

A deflection assembly for a vehicle including a vehicle component to be fastened or connected to a vehicle body. A connecting member extends through the vehicle component in an axial direction and is used for fastening the vehicle component to the vehicle body. A fastener is arranged on the connecting member axially in front of the vehicle component. To optimize a deformation zone of the motor vehicle a deflection element is arranged on the connecting rod axially in front of the nut. The deflection element having, in one disclosed example, a cross-section that increases at least in sections in axial direction towards the vehicle component. In addition, the deflection element may include an outer surface extending obliquely to the axial direction of the connecting member.

A pneumatic brake booster includes a drive piston actuating a master cylinder by a push rod while being returned to rest position by a return spring. The brake booster has a vibration damper having a part made of an elastic material working compressively, of overall parallelepipedic shape, with a length greater than the spacing of two coils of the spring prior to its installation in the brake booster and whose front and back faces are equipped with a longitudinal slit penetrating the material mass of the damper for engagement by way of those slits on the two coils of the return spring.

A brake actuation sensor device is described for a brake system of a vehicle having a strain and/or compression gage which is reversibly variable in its extension, whereby at least one electrical property is able to be changed, and an evaluation device, by which at least one electrical variable is able to be ascertained with respect to the changeable electrical property, and, taking into account the at least one ascertained electrical variable, an evaluation variable is able to be determined with respect to a brake actuating force, the strain and/or compression gage being additionally developed so that the strain and/or compression gage is able to be situated in direct or indirect contact with a brake booster housing device in such a way that a force exerted on the brake booster housing device causes a mechanical stress in the strain and/or compression gage. Furthermore, a method is described for mounting a brake actuation sensor device of a brake system of a vehicle.

A vacuum operated brake booster, comprises a casing including a base defining at least one hole, and at least one tube extending through the casing and configured to receive a screw for fastening the brake booster to a wall of a passenger compartment of a vehicle. The tube defines a rear end with a peripheral fold forming a rear groove, and an extension extending beyond the rear groove, the extension defining a first outer edge and being configured to be folded toward an outer side of the tube to form a crimping lip. The at least one hole is bordered by a recessed ring having a form complementary to that of the rear groove of the rear end of the at least one tube. The extension is configured to be folded above a second outer edge of the recessed ring and blocked in the groove.
