The window balance arm (7) has a first end (8) pivotally journalled in a first mounting bracket (9) and a second end (11) connected to a second mounting bracket (12) by means of a pivot pin (17) releasably journalled in a boring (31) of a bearing block (16). A ramp section (34) comprises an insertion channel allowing radial insertion of the pivot pin into the boring from the insertion side. An elastic plate element (37) covers the ramp section at least partially, so that the head section of the pivot pin may be inserted between the elastic plate element and the ramp section and may lift the elastic plate element away from the ramp section as the head section slides along the ramp section, and so that the pivot pin after insertion may be retained in the boring by means of the elastic plate element. |
