A safety device for a motor vehicle including a front-end structure, a front bulkhead, which separates the front-end structure from an interior, and a brake apparatus fixed to the front bulkhead and including a brake cylinder, the brake cylinder includes a device for pivoting the brake apparatus, which device, in the event of a vehicle crash, interacts with structural elements disposed in the front-end structure. The safety of a driver present in the motor vehicle may be increased. The device for pivoting the brake apparatus includes a fastening portion and a slide portion with a slide plane.

Safety device for a motor vehicle including a front-end structure

A front end of a motor vehicle, e.g., a passenger vehicle, having two longitudinal members, extending essentially parallel to the longitudinal direction of the vehicle, and an integral member on which a drive unit of the motor vehicle is mounted. The integral member has, on each side of the vehicle, a base member which extends essentially parallel to the longitudinal direction of the vehicle and is fastened in each case by a front supporting pillar and by a rear supporting pillar to one of the longitudinal members. Each longitudinal member being of deformable configuration in the longitudinal direction of the vehicle at least between the supporting pillars. In order to improve the deformation behavior of the front end, each base member is fastened exclusively via its front supporting pillar and its rear supporting pillar at the bottom to associated longitudinal members. Each base member is configured such that it has greater stiffness in the longitudinal direction of the vehicle than the respectively associated longitudinal member. The supporting pillars are configured and connected to the associated longitudinal member and/or to the associated base member such that they pivot about pivot axes extending essentially transversely with respect to the longitudinal direction of the vehicle, during a relative displacement between the base member and longitudinal member in the longitudinal direction of the vehicle.

Front end of a motor vehicle

A front-end structure for a passenger motor vehicle has a front end region, in the direction of travel, of the brake servo unit which is assigned at least one mechanical forced guidance apparatus. The latter is fixed on at least one body-shell part. In a vehicle impact, the apparatus engages with at least one movement component in the vertical direction of the vehicle, from bottom to top, on the end region of the brake servo unit.

Front-end structure for a motor vehicle

A steering column for a motor vehicle comprises struts as a support of the steering column tube on vehicle parts. At least one of these struts extends in the transverse direction of the vehicle. On at least one transversely extending strut, at least one separating point is constructed by way of which, in the event of a crash load, the strut can be divided into mutually separated strut parts. During a crash, an unfavorable movement of the steering column tube is therefore prevented.

Motor vehicle steering column which is divisible into mutually separable

A safety arrangement in the leg room of a motor vehicle has a strut of a suspension for the tube of a safety steering column hanging down from a cross member into the leg room. A crash-caused bending of the strut is connected with a raising of the forward steering column tube end. A pedal assembly is arranged laterally next to the strut on a front wall of the vehicle body bounding the leg room in the front. In order to prevent an erection of the steering column tube caused by a shock impulse in the event of a crash of the motor vehicle with a rearward displacement of the pedal assembly, at least one laterally supporting deflecting device is arranged on the pedal assembly and/or on the strut, by way of which the pedal assembly is guided past the strut.

Safety arrangement for motor vehicle leg room

A forward structure of a motor vehicle has a cross member which connects the two A-columns with one another and which is used for fixing a steering column and a knee restraint. A strut is fixed on the forward structure and extends from the cross member to a transmission tunnel extending in the longitudinal direction of the vehicle. At least two mutually overlapping strut sections of the strut have a connection area which, under a load during a crash and after overcoming a force threshold, can be elongated in a longitudinal direction while absorbing energy. A force limiting device is provided in the connection area of the strut sections in the force transmission path. Consequently, after the force threshold is exceeded, an energy reduction is achieved during a predetermined lengthening path of the connecting strut and at a constant force level so that a yielding of the impact-loaded knee restraint together with the cross member takes place with a force-limited resistance along a predetermined path distance.
