Folding rearview mirror for motor vehicles

Abstract

It comprises a base member (105) fixed to a vehicle, a housing (110) with a rearview mirror (115), a motor component (120) to rotate the rearview housing (110) relative to the base (105), two sets of ramps (10, 20) independent of each other, capable of sliding on corresponding fixed ramps (11, 21) of the base element (105) and first and second resilient means (140, 150). The ramps of the first and second sets (10, 20) have different inclinations and the resilient means (140, 150) have different spring rates from one another, depending on whether the drive housing (110) is manually or motor driven.

Description

technical field [0001] The present disclosure relates to rearview mirror arrangements for motor vehicles and, in particular, to a type of exterior rearview mirror that can be folded from an operating position substantially transverse to the The folding position is aligned with the longitudinal direction of the vehicle body, and can be folded from the folding position substantially aligned with the longitudinal direction of the vehicle body to an operating position substantially transverse to the vehicle body. Background technique [0002] Currently, foldable mirrors mounted on the exterior of motor vehicles often use electric drives for setting the mirror from an operating position to a folded position and vice versa. Thus, the housing accommodating the mirror assembly can be driven in rotation by electric means or by manual means to set it from the operative position to the folded position and vice versa, as circumstances or needs require. [0003] In fact, one of the main...

Problems solved by technology

This arrangement is complex and energy-intensive because the force exerted by a single compression spring of high spring rate, which is provided to hold the assembly in a predetermined position, should be exceeded

Furthermore, this leads to the fact that the motor has to work very hard to overcome the resistance produced by the elastic elements, which has a detrimental effect on the consumption and service life of the motor
