ABSTRACT:
An adjustable thigh support for an automotive vehicle seat wherein the tilting angle may be adjusted with reduced operational force. The adjusting mechanism comprises a rotatable shaft cooperative with a manually operative lever and lever structure for lifting up the thigh support in response to rotation of the rotatable shaft. The lever structure includes a member converting the rotational force applied to the rotatable shaft into a substantially horizontal reciprocating force and a member for converting the horizontal reciprocating force into a substantially vertical reciprocating force. The vertical force is applied to the thigh support for lifting up the latter. The member converting the horizontal force to vertical force is associated with a means for receiving and absorbing a vertical and downwards force working as reacting force against the operational force.
