Abstract: The invention discussed above provides a reinforcing element for a lower impact region of a front bumper of a motor vehicle for the protection of pedestrians during the impact of a lower leg section against the lower impact region of the front bumper. The reinforcing element is thus connected behind, in direction of travel, the lower front bumper region to the latter. The reinforcing element has a base plate with reinforcing ribs attached thereto. It extends essentially in horizontal direction, approximately over the width of the front bumper. It is thus proposed for the first time that the reinforcing element is designed as a separate plate which can be integrated in the lower bumper region. The above invention also discusses a front bumper equipped therewith for a motor vehicle.

Abstract: A plastic fender has an upper first edge area and a second edge area extending at an approximately 90° angle thereto. The fender is fixed to the vehicle body in the second edge area by a screw. Furthermore, along the first and second edge areas, a plurality of spaced-apart elongated holes is provided, which admit a mounting section of a guide element which in turn is mounted to the vehicle body with a mounting screw. On the mounting sections of the guide elements, a guide edge covering, respectively, the opposite longitudinal edges of an elongated hole is provided such that, during thermal expansion, the fender can elongate unhindered. For this purpose, the longitudinal extent of the mounting section of the guide elements is shorter than the corresponding longitudinal extent of the elongated hole.

Abstract: A fastening device on a plastic attachment for a motor vehicle, especially on a bumper, with a receptacle formed in one piece on the attachment for a part to be fastened to the attachment by means of snap fastening, which, like the receptacle, has no resiliently deformable snap fastening element, and a plug-in element having resiliently deformable snap fastening elements for position-setting snap fastening on the one hand to the part to be fastened and on the other hand to the socket on the attachment, is to be made susceptible of rational and simple manufacture. For this purpose such a fastening device provides for the engagement of at least one of the snap fastening means of the plug-in element, the receiver of the attachment has substantially oppositely lying arms of limited circumference with at least one opening each with respect to the direction of insertion of the plug-in element for the achievement of the position-fixing snap fastening in question.

Abstract: The present invention relates to a cover for closing an opening which is formed in a wall, especially in a trim part of a motor vehicle. The wall has on its inside in the area of the opening a supporting shape for the cover which makes it possible to turn the cover inserted in the opening between a closed position, wherein the cover closes the opening, and a tilted position around a tilt axis in which the cover is tilted from its closed position and is removable from the opening at the outside of the wall and/or insertable into the opening. On the cover a first ramp is formed which, when the cover is turned from its tilted position to the closed position, cooperates with a wall-mounted first guide such that the cover when in the closed position assumes a predetermined relative position.

Abstract: The invention relates to a motor vehicle bumper with an inside bumper unit which can be fastened to a vehicle body and a bumper outside unit which is fastened section-wise to the bumper inside part. According to the invention the inside bumper unit supports the outside bumper unit solely in the area of its sill portion which is to be arranged under a vehicle trunk lid. Use for lightweight bumpers for motor vehicles.

Abstract: A sonotrode for an ultrasonic welding device has an ultrasound generator that supplies high-frequency electrical energy to a converter that converts this energy into mechanical vibrations and conveys the latter, optionally via a booster, to a sonotrode (2). The sonotrode (2) is formed with a contact surface (3). In order to avoid troublesome sink marks, pegs (1) are arranged on the contact surface (3).

Abstract: A separable, form-fitting joint (5) is proposed in which one plastic component is designed as a base component (6) and another component, a cover (7), is designed as a component to be mounted on the base component (6), and the cover (7) is equipped, as viewed from the mounting direction (10), with opposing pocket-shaped receptacles (13, 14, 20, 21) which are formed on cover (7) by tongues (16, 17, 22, 23) on the cover (7) and which accommodate the insertion of flange-shaped edge sections (9, 12) of the base component (6).

Abstract: The bumpers of motor vehicles nowadays are being used to an increasing extent to carry components of small size in which their position on a bumper is especially advantageous for their operation due to its exposed location. For example, it is known to build into the bumpers of vehicles flashers, parking lights and especially distance sensors (parktronic sensors, abbreviated PTS) which detect the distance from other vehicles or obstructions and are designed as parking aids. The components must be mounted such that when the bumpers are affected, especially by mechanical shock, any loosening or dropping out will be impossible. At the same time the mountings must be able to be made simply and inexpensively. It is therefore proposed according to the invention that the tongues be affixed by feet to the bumper, or in case of a bumper of modular design, to one of its modules, and be positioned opposite the opening.

Abstract: The invention relates to a vehicle with an energy-absorbent structure (1) and with a spoiler (2) made in one piece with the bumper or fastened thereto. To improve protection of pedestrians, it is proposed that spoiler (2) be limited in its deflection lengthwise of the vehicle by a support (3) mounted on the vehicle, with support (3) being located a radial distance behind spoiler (2).

Abstract: A front or rear bumper (1) for a motor vehicle has a main part which is disposed transversely to the vehicle and side parts which extend approximately in the longitudinal direction of the vehicle. The bumper (1) so secured at points on the vehicle. To prevent the side parts of the bumper (1) from permanently deforming the sheet metal bodywork or mudguard (5) in the event of an accident, the system for securing the side parts, in particular at their ends, is designed so as to be detachable.

Abstract: A bolt-on part, especially a front or rear bumper, of a motor vehicle, that can be exposed especially in its outer wall to impact energy and is mounted pointwise on a structural member of a motor vehicle, with the connection between the structural member and the bolt-on part consisting of pin-shaped fastening devices on one of the two parts to be connected and recesses in the other of the two parts, is intended to dissipate as much deformation energy as possible by coming loose from the structural member under the influence of an impact in the lengthwise direction of the bolt-on part. For this purpose, at least one of the recesses in each case is closed circumferentially and is located at the end furthest away in the direction of action from the point where the impact energy is applied. The other recesses are open circumferentially and are in the form of grooves inclined at less than .alpha.=90.degree.
