Abstract:
1. A ventilation arm component comprising a first element, a second element, the second element having a diameter larger than that of the first element so that the first element can be inserted into the second element and the two elements can be displaced relative to each other in a telescopic manner, a glide sleeve that is arranged between the first element and the second element, the glide sleeve including a first part that retains the glide sleeve at the second element, the glide sleeve including a second part that makes contact with the first element under a force that can be adjusted and that is united with the first part, and wherein the second part is located in front of a first end of the second element, a circumferentially continuous circular part that lies in contact with the glide sleeve and is arranged for the transfer of the force against the second part of the glide sleeve that is held in contact with the first element, and a tensioner for increasing or decreasing the circumference of the circumferentially continuous circular part by circumferentially de-tensioning or tensioning the circumferentially continuous circular part, respectively, wherein the tensioner is located in a compartment in the glide sleeve, and the glide sleeve has at least one opening that allows access to the tensioner from outside the glide sleeve by an adjustment tool that can be inserted through the at least one opening for adjusting the tensioner to increase or decrease the circumference of the circumferentially continuous circular part and then removed after the tensioner has been adjusted.
