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. The plug-in element is provided with pockets for the engagement of the arms of the receiver of the attachment, in which the arms, with their freely terminating end portions, are fixed in position on all sides in a plane perpendicular to the direction of insertion of the plug-in element.

Fastening device on a plastic attachment for motor vehicles

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. Alternatively or additionally a second ramp is formed on the cover, which cooperates with a wall-mounted second guide when the cover is turned from the closed position to the tilted position, such that the cover when in the tilted position assumes a predetermined position relative to the wall.

Cover for closing an opening in a wall

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.

Motor vehicle bumper and motor vehicle

A motor vehicle bumper has an internal bumper part mountable on a motor vehicle body. An external bumper part is fastened to the internal bumper part. The internal bumper part includes a base body fastened to the motor vehicle body and a holding bar fastened by a releasable fastener to the base body. An edge of the external bumper part is releasably fastened thereto. The holding bar is unfastened from the base body by the application of force to the external bumper part on the lengthwise direction of a motor vehicle and to the vehicle body.

A front or rear bumper ( ) 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 ( ) so secured at points on the vehicle. To prevent the side parts of the bumper ( ) from permanently deforming the sheet metal bodywork or mudguard ( ) 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.

Securing system for integrally shaped bumper

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. to the acting direction of the impact energy in such fashion that the bolt-on part that deforms under the impact energy can come loose from the structural member without deformation of the structural member, at the recesses that are formed as grooves.
