The legrest comprises a release control device comprising at least two locking pins (30, 30') intended to cooperate with a lock chip element (20) provided with a series of holes (21, 21') corresponding to the different desired slope positions of the legrest. Said locking pins (30, 30') are mounted on a raise chip element (90) provided with at least one tilt angle surface (97, 97') designed to cooperate with at least one tilt angle gliding surface (67, 67') of a turn chip element (60). A torsion spring (70) cooperates with both the turn chip element (60) and the raise chip element (90), the whole being arranged to have the raise chip element always returned to its original position. A compression spring (80) acts between the raise chip element (90) and the turn chip element (60) to secure that the locking pins (30, 30') lock into the lock chip element (20). |
