摘要

1. Anti-skid device for vehicle wheels provided with treads, especially tires for surfaces covered with ice or snow, consisting of a support disk attachable to the wheel disk or rim with a number of slip arms which dicurren radially equally spaced with a previously curved profile bears on its outer side at their free ends a profile gripping or tips for tires and overlapping the tread of the tire, with such a profile of plastic material or other suitable material, wherein the device (100) comprises a support (120) disc attached to the wheel disk or rim (11) which carries a number of slip spleens (140) with a previously curved profile, which overlaps the surface tread (14) of the tire, rotatable about axes (141) running parallel to the supporting axis of the wheel disk or rim (117) and in that each arm s slip (140) is provided with an accumulation of material (148) in the bent portion (143b) to increase the weight to counteract the centrifugal force. 2. Device according to claim 1 antideslizane, wherein each slip arm (140) is made of a synthetic elastically yielding material and is provided outside of a reinforcing rib (149) extending in the longitudinal direction of the arm anti-slip. 3.
