Problems solved by technology

However, this solution locally affects the properties of the beam and degrades the force intrusion properties
Furthermore, this necessitates a separate drilling step and a separate step for applying the rivets, which increases cost and process length

Embodiment Construction

[0034] refer to figure 1 , provides a perspective view of a bumper system according to the invention. The bumper system (100) comprises a bumper beam (10) and two attachment means (20) for mounting said bumper beam to a longitudinal beam (not illustrated) of a vehicle. The bumper beam includes a front wall (11) and a rear wall (12) spaced apart by the wing walls. Each attachment means is formed by a hollow section profile (21) having a first end (22) to be fixed to said longitudinal beam of the vehicle structure and a second end (23), the first end (23) The two ends are designed to be attached to said bumper beam (10). A flange (41) extends substantially beyond said vertical front wall (11) of the bumper beam (10), which flange can be used to secure a component in front of the front wall.

[0035] refer to figure 2 , provides a detailed perspective view of one embodiment of the second end of the attachment device (20) according to the invention, showing flanges (41) and (...

Abstract

The invention concerns an attachment means (20) for mounting a bumper cross-beam (10) having a vertical front wall (11) and a vertical rear wall (12) spaced apart by at least one transverse wall (13) onto a vehicle structure, the said attachment means having a first end (22) to be fixed to the said vehicle structure and a second end (23) designed to be attached to the said bumper cross-beam, the said attachment means being made from a hollow section profile (21), the periphery of which comprises opposite side walls (24 and 25) and substantially parallel opposite outer walls (26 and 27), characterised in that the said second end (23) comprises at least one flange (41), which can extend substantially beyond said vertical front wall (11) after mounting said bumper cross beam (10), and on which a component (50) is attached to the flange (41) in front of said vertical front wall (11). The invention is useful in particular for assembling additional parts in the front part of the cross-beam, without affecting the properties of the cross-beam and deteriorating the force intrusion properties.

Description

technical field [0001] The present invention relates to an attachment device for mounting a bumper beam to a vehicle structure. More specifically, the invention relates to the design of the end of said attachment device to be fixed to the bumper beam. Such attachment means are advantageously deformation elements, also known as "crash-boxes" or "C-boxes", which are designed to absorb by plastic deformation in the event of a vehicle crash As much kinetic energy as possible. Background technique [0002] The bumper beam includes generally vertical front and rear walls which act as compression struts and tension struts, respectively, in the event of an impact and which are Spaced apart by flanking walls. These flanking walls are usually horizontal upper and lower walls. The bumper beam is often an extruded profile, advantageously in aluminum alloy, comprising a hollow section member having at least one chamber delimited by said vertical front and rear walls and horizontal up...
