Ball arrest device for road vehicle door fitting - has guide bush for slide guiding the arresting means in which screw pressure spring is coaxially arranged

摘要

The lateral outward bending of the screw pressure spring is limited by the guide bush and the bush (5) in the length area of the greatest outward bending of the screw pressure spring (8) has a radial, elastic, pliable guide and support area. The guide and support area is formed by a support ring (12) which encloses with virtual lack of clearance the winding of the screw pressure spring (8). The guide bush (5) is of bendable elastic material, and a narrowed longitudinal section of it itself acts as support ring (12). USE/ADVANTAGE - A road vehicle door fitting ball arrest device with which the occurrence of crack noises via the spring windings is adequately prevented.
