Pivot joint system and rear view device therewith

A pivot joint system of a rear view device, comprising:

• a base to be fixed to a vehicle;
• a head rotatable relative to the base;
• two components that rotate with respect to one another around an axis to control rotation of the pivot joint system from a first set position to at least one second set position, each of said two components comprising a cylindrical section and a resilient means being arranged within a cylindrical space between the cylindrical sections to act between said two components, the first component being part of or fixedly connected to the head, the second component being part of or fixedly connected to the base, and the resilient means comprising a torsion spring arranged concentrically around the pivot axis,
• a detent means for securing the first set position of the first component relative to the second component until a predetermined torsional load is applied rotating the first component relative the second component;
• and
• a bolt that has a longitudinal axis falling together with the pivot axis, the bolt providing a support extension for a first end of the spring, and a second end of the spring abuts against a shoulder of the second component cylindrical section,
• wherein the torsion spring has a first tail at a first end which is attached to the first component, and a second tail at the second end which is attached to the second component so that a torsional load applied onto the spring when rotating the first component out of the first set position relative to the second component into the at least one second set position relative to the second component forces the first component back into the first set position relative to the second component with the first set position being defined by a driving position of the head and the at least one second set position comprising a knocked out position of the head,
• wherein the detent means lifts the first component relative to the second component when rotating in the at least one second set position resulting in a compression of the spring so that relaxation of the spring assists in forcing the first component back into the first set position relative to the second component, and
• wherein at least one of
• the first component cylindrical section is provided with a step against which the second component cylindrical section is forced by the spring, or
• the pivot joint system further comprises a washer that is arranged between the support extension and the spring as well as the first component cylindrical section with the first component cylindrical section being concentrically arranged around the bolt, the spring being concentrically arranged around the first component cylindrical section, and the second component cylindrical section being concentrically arranged around the spring.
