A swivel joint system for pivotally connecting a mirror to a vehicle includes a first arm, a second arm, a locking pin, a spring element and a centering element. The first arm has first and second bearing shells. The second arm has a first counter bearing shell and a second counter bearing shell. The counter bearing shells are disposed between the first bearing shell and the second bearing shell. A first latching surface of the first counter bearing shell contacts and presses against a second latching surface of the first bearing shell. The locking pin passes through the first bearing shell, the second bearing shell and a hole in the centering element. The second arm swivels relative to the first arm about a joint axis that is oriented co-axially to the locking pin. The spring element pushes the locking pin away from the first counter bearing shell.

1. A swivel joint system for supporting an indirect imaging device on a vehicle, comprising: a first arm with a first bearing shell, a second bearing shell and a locking shell;a second arm with a bush bearing, wherein the bush bearing has a first counter bearing shell and a second counter bearing shell, wherein the bush bearing is disposed between the first bearing shell and the second bearing shell, wherein a first latching surface of the first counter bearing shell contacts a second latching surface of the first bearing shell;a locking pin that passes through the second bearing shell, the bush bearing and the first bearing shell, wherein the locking pin has a ring collar disposed towards a proximal end of the locking pin, wherein the locking pin is oriented co-axially to a joint axis, and wherein the second arm swivels relative to the first arm about the joint axis; anda coil spring disposed between the ring collar and the first counter bearing shell, wherein the locking pin passes through the coil spring, and wherein the coil spring presses the first counter bearing shell up into the first bearing shell by pushing down against the ring collar such that catches disposed on the second latching surface engage in latching recesses of the first latching surface, wherein bayonet extensions are disposed at a proximal end of the locking pin, wherein bayonet collar segments are disposed in the first bearing shell, and wherein the locking pin is locked to the first arm by the bayonet extensions being slid through the bayonet collar segments and undercuts of the bayonet extensions engaging the bayonet collar segments. 2. The swivel joint system of claim 1, wherein the coil spring pushes the locking pin away from the first counter bearing shell. 3. The swivel joint system of claim 1, further comprising: a centering element with an opening through which the locking pin passes, wherein a peripheral exterior surface of the centering element presses against a bearing of the second counter bearing shell so as to center the locking pin radially with respect to the second counter bearing shell. 4. The swivel joint system of claim 1, further comprising: a centering element with an opening through which the locking pin passes, wherein the locking pin has a pin shaft, wherein the ring collar is conical, wherein a lower side of the centering element is adjacent to the conical ring collar, and wherein the lower side slants down and away from the pin shaft at an inclination angle that corresponds to a cone angle of the conical ring collar. 5. A swivel joint system for supporting an indirect imaging device on a vehicle, comprising: a first arm with a first bearing shell, a second bearing shell and a locking shell:a second arm with a bush bearing, wherein the bush bearing has a first counter bearing shell and a second counter bearing shell, wherein the bush bearing is disposed between the first bearing shell and the second bearing shell, wherein a first latching surface of the first counter bearing shell contacts a second latching surface of the first bearing shell;a locking pin that passes through the second bearing shell, the bush bearing and the first bearing shell, wherein the locking pin has a ring collar disposed towards a proximal end of the locking pin, wherein the locking pin is oriented co-axially to a joint axis, and wherein the second arm swivels relative to the first arm about the joint axis;a coil spring disposed between the ring collar and the first counter bearing shell, wherein the locking pin passes through the coil spring, and wherein the coil spring presses the first counter bearing shell up into the first bearing shell by pushing down against the ring collar such that catches disposed on the second latching surface engage in latching recesses of the first latching surface; anda centering element with a contact surface, wherein the coil spring is compressed between the first counter bearing shell and the contact surface, wherein the ring collar is conical, wherein the centering element is disposed between the coil spring and the conical ring collar, and wherein the centering element spreads out radially when pressed by the coil spring onto the conical ring collar. 6. The swivel joint system of claim 5, further comprising: a mirror attached to the second arm. 7. The swivel joint system of claim 5, wherein the first arm is attached to an exterior of a vehicle. 8. The swivel joint system of claim 5, wherein the first bearing shell has a first bearing, wherein a locking pin girthed surface shell is disposed at a distal end of the locking pin, and wherein the locking pin is locked to the first arm by the locking pin girthed surface shell sliding through the first bearing. 9. The swivel joint system of claim 5, wherein the second bearing shell has a second bearing, wherein a locking pin girthed surface shell is disposed at a proximal end of the locking pin, and wherein the locking pin is coaxially centered in the second bearing by the locking pin girthed surface shell fitting into the second bearing. 10. The swivel joint system of claim 5, wherein a locking pin girthed surface of the locking pin slides inside a hole in the first counter bearing shell as the second arm rotates about the joint axis with respect to the first arm. 11. The swivel joint system of claim 5, wherein a locking pin girthed surface towards a proximal end of the locking pin slides inside a hole in the second counter bearing shell as the second arm rotates about the joint axis with respect to the first arm. 12. The swivel joint system of claim 5, wherein the contact surface of the centering element is divided into a plurality of tongues that extend radially outwards, wherein each of the tongues has an associated outer cylindrical wall segment that extends from its associated tongue in an axial direction, and wherein each outer cylindrical wall segment has a peripheral exterior surface that presses against a bearing of the second counter bearing shell.
