The at least one vision device (10) is positioned in or at an outer housing (7) and pointing to an outside of the outer housing (7). The outer housing (7) is defined by a housing cover (8) and a housing base (9). A housing (20) of the vision device (10) has a first spherical outer contour (21) and a second spherical outer contour (22). The first spherical outer contour (21) and the second spherical outer contour (22) provide in cooperation with the housing base (9) and in cooperation with a mounting element (40) a form and force fitting mount of the vision device (10) in the housing outer (7). ## Claims ### Claim 1 A driver monitoring system, comprising, at least one vision device positioned in or at an outer housing and pointing to an outside of the outer housing, wherein the outer housing is defined by a housing cover and a housing base wherein the housing base has at least one receptacle which defines a spherical portion, a vision device housing having a first spherical outer contour and a second spherical outer contour, wherein the first spherical outer contour and the second spherical outer contour cooperate with the housing base and with a mounting element to provide a form and force fitting mount of the vision device in the outer housing, wherein the second spherical outer contour of the vison device is in a form fitting contact with the spherical portion of the least one receptacle and wherein the least one receptacle has a central pin which reaches into a channel provided at the second spherical outer contour of the vision device housing. ### Claim 2 (depends on 1) The driver monitoring system as claimed in claim 1, wherein the first spherical outer contour and the second spherical outer contour of the vision device housing are smooth or have an array of shallow grooves formed on at least one of the first spherical outer contour and the second spherical outer contour. ### Claim 3 (depends on 1) The driver monitoring system as claimed in claim 1, wherein the vision device is a vision camera or an infrared module. ### Claim 4 (depends on 1) The driver monitoring system as claimed in claim 1, wherein the mounting element of the driver monitoring system is in a form and force fitting contact with the first spherical outer contour of the vision device housing. ### Claim 5 A driver monitoring system comprising, at least one vision device positioned in or at an outer housing and pointing to an outside of the outer housing, wherein the outer housing is defined by a housing cover and a housing base, a vision device housing having a first spherical outer contour and a second spherical outer contour, wherein the first spherical outer contour and the second spherical outer contour cooperate with the housing base and with a mounting element to provide a form and force fitting mount of the vision device in the outer housing, wherein the mounting element is in a form and force fitting contact with the first spherical outer contour of the vision device housing, and wherein the mounting element is a flange of the housing cover having a flexible area with a topology mating with the first spherical outer contour of the vision device when the housing cover and the housing base are joined. ### Claim 6 (depends on 5) The driver monitoring system as claimed in claim 5, wherein the housing base has at least one receptacle which defines a spherical portion, wherein the second spherical outer contour of the vison device is in form fitting contact with the spherical portion of the least one receptacle. ### Claim 7 (depends on 5) The driver monitoring system as claimed in claim 5, wherein the least one receptacle has a central pin which reaches into a channel provided at the second spherical outer contour of the vision device housing. ### Claim 8 (depends on 5) The driver monitoring system as claimed in claim 5, wherein the topology mating the first spherical outer contour of the vision device is present when an elongation of the flexible area is joined with a clinching dome of the housing base. ### Claim 9 (depends on 5) The driver monitoring system as claimed in claim 5, wherein the mounting element has a plurality of flexible fingers having a tip portion, wherein the tip portions are in form and force fitting contact with at least one shallow groove on the first spherical outer contour of the vision device when the housing cover is joined with the housing base. ### Claim 10 (depends on 5) The driver monitoring system as claimed in claim 5, wherein the mounting element has oppositely arranged claw flanges, wherein the claw flanges are in form and force fitting contact with the first spherical outer contour of the vision device when the housing cover is joined with the housing base. ### Claim 11 (depends on 9) The driver monitoring system as claimed in claim 9, wherein the mounting element is attached via a first flexible strip to the housing cover, and a second flexible strip of the mounting element is attached to a fixing which is mounted to the housing base. ### Claim 12 (depends on 5) The driver monitoring system as claimed in claim 5, wherein the mounting element is a hair pin spring with a spherical contact area which is in a form and force fitting contact with the first spherical outer contour of the vision device when the hair pin spring is mounted to the housing base. ### Claim 13 (depends on 5) The driver monitoring system as claimed in claim 5, wherein the mounting element is a sheet spring with an outer half ring and two inner quarter rings, wherein the inner quarter rings embrace the first spherical outer contour of the vision device when the sheet spring is pushed down to the housing base. ### Claim 14 (depends on 5) The driver monitoring system as claimed in claim 5, wherein the vision device is an infrared module which is mounted in a form and force fitting manner in the outer housing or outside the outer housing. ### Claim 15 (depends on 14) The driver monitoring system as claimed in claim 14, wherein an upper part and a lower part of a pincer have a spherical topology, which are in form and force fitting contact with the first spherical outer contour and the second spherical outer contour of the infrared module.
