Car seat adjuster rail system employs two-legged spring to exert constant tension on rails off base and side supports using metal spring.

摘要

The tensioner spring (1a) exerts constant pressure in its effective range which should match at least rail (5a,6a) dimensional fluctuations over the spring path (s). The spring has a degressive characteristic and is curved in form and supported at right angles to the spring path (s) by means of a base (3a) whence the free legs (2a) to tension the rails thrust off the rails. The leg is additionally supported normal to the spring path (s) and the two free legs bear against one another at their ends and are also joined over the base area (3a). In a variant, the spring comes in two parts each with leg and the two legs joined via an adapter. The base (3a) uses its fixing sector (4a) to fit the spring in a rail (5a) recess (52a).
