A motor vehicle bumper has a crossmember fixed to the body and an impact-confronting collision part. Non-regenerable deformation members are arranged between the collision part and the crossmember, at least in the region of support points, and the impact-confronting collision part is secured to the crossmember via fastening bolts passing through the deformation members. During a deformation of the non-regenerable deformation members, the collision part is displaceable in the longitudinal direction of the vehicle in order to increase the deformation capacity, while preserving the indicator effect of the support points. The collision part is designed as a trim part encasing, at least in the region of the support points, a core consisting of elastically deformable foam. With the exception of the region of the support points, the bumper has a gap on the energy-absorber side. Each fastening bolt is surrounded by a spacer sleeve supported, at one end, on the head underside if the sleeve and, at the other end, on the crossmember fixed to the body.

Motor vehicle bumper

A bumper for a motor vehicle with a support part which, supports and separates an impact-near and an impact-remote layer of energy-absorbing form. The supporting part is held by resilient holders on a support fixed to the vehicle. A panelling covers the impact-near layer towards the front and is fixed to the support part. A skirt adjoins toward the bottom. In order to increase the absorbency and retain a pedestrain-protective configuration, the support part is designed as a stiff load distributing support and the panelling is fastened to it and merges integrally with the skirt.

Bumper for a motor vehicle

A bumper arrangement for an automotive vehicle is disclosed which includes a bending-resistant bumper support resting on parts affixed to the vehicle, an undulating leaf spring extending over the length of the bumper arranged in front of this bumper support, and a cover which can be locked to the bumper support and which serves to hide the leaf spring from view. The leaf spring is fashioned integrally with the bumper support, and is preferably made of a reinforced synthetic resin. The wavy windings of the leaf spring are aligned in the support zone extending transversely with respect to the automotive vehicle, in the longitudinal vehicle direction, and, in the laterally wrapped-around end zones of the support, approximately in the transverse vehicle direction. Energy absorbing elements and impact buffers are interposed between the undulations of the leaf spring and between the bearing support and the adjacent section of the leaf spring.

Bumper for an automotive vehicle

A bumper arrangement for a motor vehicle, especially an automobile, with the bumper arrangement including a bending-resistant support mounted on a part integrally secured with the motor vehicle. A front of the support accommodates a preferably replacable energy absorber composed of at least one component. The energy absorber itself is partially surrounded by a shell made of a viscoelastic material. The shell is connected to a covering part of viscoelastic material having a downwardly projecting skirt segment and an upwardly extending segment which is extended in a direction toward adjoining body portions of the motor vehicle. A front side of the support is made essentially flat and is adapted to receive a middle segment of the covering part. For attachment of the shell to the covering part locally discontinuous guide grooves are provided in an area of the upper segment and skirt segment, the guide grooves being adapted to lockingly accommodate the appropriate projections or ends of the shell.

Bumper for motor vehicles

A side guard or lateral protection arrangement for motor vehicles, wherein at least one reinforcement, extending substantially in the longitudinal direction of the vehicle, is arranged within each of the side doors. The reinforcements are braced in case of a force effective in the longitudinal direction of the vehicle, with each end directly or indirectly against a component fixedly mounted to the vehicle or against a further reinforcement associated with an adjacent door. This bracing takes place in the longitudinal direction of the vehicle. The reinforcements are axially adjustable in their lengths so as to bridge a space between an end of the reinforcement means and the component fixedly mounted to the vehicle or further reinforcement, which space results from manufacturing tolerances in the construction of the motor vehicle.

Side guard for motor vehicle

A bearer, especially a longitudinal bearer of a motor vehicle frame, which is constructed as hollow profile and includes a deformable section dissipating impact energy; the walls of the longitudinal bearer have different strength characteristics as a result of a treatment of these areas changing the strength of the wall material compared to non-treated areas; a greater strength thereby exists in the treated wall areas than in the untreated areas.

Hollow bearer for vehicles and method for its manufacture

A motor vehicle bumper consisting of an approximately U-shaped relatively elastic base body, of an apron made of elastic plastic material which covers the forwardly disposed web of the base body and is drawn around up to the flanges adjoining the web on both sides, and of a cover constructed as decorative strip and covering at least the remaining visible part of the upwardly disposed flange; the cover is thereby pivotally connected with the base body exclusively by fastening elements disposed substantially in the axial direction of the two bumper supports while the upper flange is surrounded at the end face by clamps formed out of the cover within the area of the bumper supports and possibly also within areas displaced outwardly with respect thereto.

A bumper support member for motor vehicles which consists of glass-fiber-reinforced synthetic resinous material, is profiled approximately U-shaped and is additionally strengthened by giving the support member a wall thickness that is essentially matched over its length to a bending moment curve calculated from the critical load cases and by providing the support member with fastening elements that are formed-on and/or formed-in for mounting and support thereon of parts such as shock absorbers and towing eyes or hooks.

Hollow bearer for vehicles

A longitudinal bearer support for a forward longitudinal bearer supported under angular bending at the end wall of a self-supporting motor vehicle body, whereby the end wall is locally bulged out in the direction of the vehicle end within the connecting area of each forward longitudinal bearer in such a manner that a form-rigid body results; each forward longitudinal bearer is forked in its approach at the form-rigid body and the resulting arms at least partially surround the form-rigid body; two arms are created by the forking which, extending either parallelly to one another or at an angle to one another, lead to the subfloor.

Forward longitudinal bearer supported at the vehicle end wall of a

A forward longitudinal bearer of a motor vehicle constructed as closed, hollow bearer with an impact-near energy-absorbing part which is so composed section-wise that three series-connected zones result, of which the center zone is located within the area of aggregate support points and exceeds the two adjoining zones as regards their rigidity by the use of materials of increased strength and/or greater wall thickness.

Forward longitudinal bearer constructed as closed hollow bearer

A bumper for a motor vehicle having a support member that extends over the vehicle width and is supported at fixed vehicle parts; a preferably surface-finished cover is provided in the upper area of the support member which is adjoined by a covering member that covers off at least the remaining visible area of the support member; the cover is thereby drawn forwardly up to the end face of the support member and its end-face end area is supported at the support member and is covered off by the covering member.

A longitudinal bearer constructed as hollow profile of a motor vehicle frame, which is equipped with introduction places for introducing chassis forces into the frame and into the longitudinal bearer and with a longitudinal deformable bearer section arranged outside of the introduction places and dissipating impact energy; the longitudinal bearer section which by reason of different wall thicknesses has a resistance to buckling that increases in the direction toward the vehicle center, is transversely subdivided over its length at least into two bearer pieces connected with each other by circumferential seams; the wall thickness of a respective bearer piece becomes greater and/or the wall quality thereof becomes better in the direction toward the vehicle center from bearer piece to bearer piece than the wall thickness and/or the wall quality of the bearer piece disposed in front thereof.

Longitudinal bearer and method of constructing same

A vehicle bumper formed by a rearwardly opening U-shaped profile member having arranged therein reinforcements fashioned as vertically arranged ribs extending in the longitudinal direction of the vehicle. The ribs are formed of a metallic material and are individually secured with the bumper which is fashioned from sheet steel.

Vehicle bumper

A longitudinal bearer of a motor vehicle frame, constructed as hollow profile which is provided with places for the introduction of chassis forces into the frame and into the longitudinal bearer and which includes a longitudinal bearer section arranged outside of the introduction places and dissipating deformable impact energy; this longitudinal bearer section, by reason of a differing wall thickness progress, has a resistance to buckling that increases in the direction toward the vehicle center; to that end at least the longitudinal bearer section located outside of the force introduction places is longitudinally subdivided over its length at least into two bearer parts consisting of sheet-metal profile members which are connected with each other along longitudinal seams, whereby the sheet-metal members have different wall thickness while the longitudinal seams extend obliquely to the longitudinal axis of the longitudinal bearer section such that the sheet-metal bearer member with greater wall thickness has a greater share in the circumference of the longitudinal bearer section in areas thereof located nearer the vehicle center than in areas thereof located nearer the end of the vehicle.
