Problems solved by technology

[0002] Currently, these references, i.e. the parts that make the bumper in place on the vehicle structure as reference and fixation, are built very early in the installation block diagram and in different assembly steps, which creates geometrical deviations between them
[0003] However, once the frame is set on the structure, usually the bumper needs to meet certain size constraints, such as its position relative to surrounding body members

Embodiment Construction

[0025] To simplify the description below, these figures are oriented along the X, Y, Z system axes that generally define the orientation of the car:

[0026] -X axis is the longitudinal axis of the car, facing from back to front;

[0027] - The Y axis is the horizontal axis of the car, and its orientation is from right to left;

[0028] -Z axis is the vertical axis of the car, and its orientation is from low to high;

[0029] The position and orientation terms used below are clearly relative to the system axis.

[0030] figure 1 and 2 A part of the front bumper 10 intended to be mounted on a vehicle structure 12 is shown in a simplified manner.

[0031] The bumper 10 includes a bumper frame 14 that extends substantially transversely with respect to the vehicle and includes a first lower portion 16 and a second upper portion 18 .

[0032] On both sides of the frame 14 , the lower part 16 is provided with compensating workpieces 20 adjustably mounted on the frame 14 .

Abstract

The method of the invention, where the bumper (10) includes a bumper armature (14) and the structure (22) includes an understructure (22) comprising a cross beam (26), rails (24) and fastening brackets (28) carried by the rails (24), comprises positioning and securing the armature (14) onto the structure (12) relative to predetermined geometrical references, some of which are connected to the fastening brackets (28) while others are connected to the beam (26). More precisely, a first portion (16) of the armature (14) is fitted with compensation parts (20) adjustably mounted on the armature (14), a second portion (18) of the armature (14) is attached on the fastening brackets (28), the position of the compensation parts (20) being such that they are spaced from the beam (26) when said attachment is done; the placing of the armature (14) onto the structure (12) is completed by moving the compensation parts (20) so as to bring them in contact with the beam (26).

Description

technical field [0001] The present invention relates to a method of mounting a bumper on a motor vehicle structure, the bumper comprising a bumper frame, and the structure comprising a base consisting of cross members, longitudinal members and fixed brackets supported by the longitudinal members, according to the invention In the method, the frame is positioned and fixed to the structure with reference to predetermined geometric references (références géométriques), some of which are connected to the fixing brackets and the other part of which are connected to the beams. Background technique [0002] Currently these references, i.e. the parts that make the bumper in place on the vehicle structure as a reference and fixation, are built very early in the installation block diagram and in different assembly steps, which creates geometrical deviations between them . [0003] However, once the frame is set on the structure, usually the bumper needs to meet certain size constrain...
