Fixing device for automobile wiper system support piece comprises damper unit with central bore for passage of tubular fixing elements having deformable upper part with axial tongues able to be subjected to deformations

摘要

The fixing device (100) for a support piece (200) for a wiper system on an automobile structure element (300) comprises a cylindrical damper unit (1) with a central bore (13) for the passage of fixings to the structure element. The fixings comprise a first tubular element (21) in the bore and a mounting threaded rod (31) partly inserted in the tubular element. A pin (2) comprises the first tubular element and a second tubular element (22) in two adjacent parts (22A,22B). In the upper deformable part (22A) are two axial tongues (220,221,222) able to be subjected to two successive types of deformation. The tongues deform against the lower transverse outer face of the damper unit during clamping, and under the effect of an impact load applied from the outside of the vehicle
