Definitions

• the invention relates to a projector support for a motor vehicle and in particular a halogen-type projector support bi-function.
• Some luminous projectors especially dual-function halogen projectors, are incompressible to impact and pose a risk of injury in the event of impact with a pedestrian, especially in the area of the femur-hip pedestrian.
• damping means capable of absorbing part of the energy of a shock.
• damping means may be elastically deformable, or cause the projector to tilt, so that they are relatively complex and expensive to manufacture and assemble.
• a motor vehicle headlight fusible support characterized in that it comprises: a support leg of the headlamp, the support leg having a longitudinal shape and being designed to withstand longitudinally a calibrated weight,
• At least one rupture zone calibrated to rupture under a predetermined force.
• the support according to the invention can thus support a projector without altering the geometric position of the latter because of the relative adjustment of its support bracket and its fixing base relative to each other.
• the longitudinal shape of the support leg allows vertical positioning of the fuse holder between the projector and the vehicle structural element, to provide effective support to the projector via the structural element.
• this support leg is arranged to withstand a calibrated weight, for example 30 kg, which may correspond to a person resting on the projector.
• the fuse carrier also does not change the ability of the projector to fade, due to the presence of at least one calibrated breaking zone.
