Ski Suspension
US Patent:
4979761, Dec 25, 1990
Filed:
Sep 14, 1989
Appl. No.:
7/407292
Inventors:
William F. Rohlin - Jackson MI
International Classification:
A63C 500
US Classification:
280607
Abstract:
A suspension for skis including a pair of vertically spaced plates, the lower plate being mounted to the ski and the upper plate having a boot attached thereon. Compression springs interposed between the suspension plates absorb shock and impact, and the suspension includes lateral alignment stabilizers and pivoted links interconnecting the plates which permit vertical movement but restrain the plates against lateral angular variations whereby the pressure applied to the ski edges is maintained during vibration absorbing. A foam material between the plates damps the suspension action and protects the interior components.
